RESUMEN

Variant anatomy in the axillary region is of great clinical significance. It is one of the most frequently accessed regions for radical dissection surgery. During routine dissection of embalmed cadavers, we found a rare case of two accessory muscular slips emerging from the lateral border of latissimus dorsi (LD) and the inferolateral border of pectoralis major (PM), crossing the neurovascular structures in the axilla and merging distally together to the brachial fascia at the upper end of humerus below the bicipital groove. The accessory slip from LD is commonly referred to as the "axillary arch" in literature. We identified the accessory slip from the PM crossing over the axilla as pectoralis quartus. These aberrant slips can cause neurovascular compression in the axilla and can have clinical implications. Prior knowledge of the variant anatomy is the key to successful surgery in the axilla, thereby avoiding inadvertent injuries and post-operative complications.

RESUMEN

INTRODUCTION: With 60,000 cases per year, breast cancer is the most frequent type of cancer in France, and a quarter of these cases require mastectomy. Following the surgery, breast reconstruction can be indicated. Two of the available techniques are breast implants (BIs) and muscle-sparing latissimus dorsi (MSLD). The aim of this study was to compare postoperative complications of each approach and thus help the surgeon and the patient in making an informed decision before surgery. MATERIALS AND METHODS: This descriptive, retrospective and single-centre study was conducted in the Croix Rousse hospital in Lyon (France) between 1 July 2018 and 1 July 2023. It included women aged ≥18 years who underwent mastectomy followed by (immediate or delayed) breast reconstruction with MSLD or BI. Complications were recorded and evaluated using the Clavien-Dindo classification. RESULTS: Over the course of the study, 92 patients were managed with MSLD reconstruction and 63 patients with BI. We observed a complication rate of 62% in the BI group and 39% in the MSLD group (odds ratio [OR]=0.16; p < 0.005). Body mass index (BMI) significantly impacted this rate (OR=1.11; p = 0.01), whereas smoking status and diabetes did not. No complication occurred more predominantly than others. A second surgery was required more often in the BI group (p < 0.005). There were no severe complications (>Grade 4). CONCLUSION: MSLD predicted fewer complications and was associated with a shorter hospital stay compared with implants, suggesting that it may be a preferable option for breast reconstruction.

RESUMEN

Aims: Favourable short-term outcomes have been reported following latissimus dorsi tendon transfer for patients with an irreparable subscapularis (SSC) tendon tear. The aim of this study was to investigate the long-term outcomes of this transfer in these patients. Methods: This was a retrospective study involving 30 patients with an irreparable SSC tear and those with a SSC tear combined with a reparable supraspinatus tear, who underwent a latissimus dorsi tendon transfer. Clinical scores and active range of motion (aROM), SSC-specific physical examination and the rate of return to work were assessed. Radiological assessment included recording the acromiohumeral distance (AHD), the Hamada grade of cuff tear arthropathy and the integrity of the transferred tendon. Statistical analysis compared preoperative, short-term (two years), and final follow-up at a mean of 8.7 years (7 to 10). Results: There were significant improvements in clinical scores, in the range and strength of internal rotation and aROM compared with the preoperative values in the 26 patients (87%) who were available for long-term follow-up. These improvements were maintained between short- and long-term follow-ups. Although there was a decreased mean AHD of 7.3 mm (SD 1.5) and an increased mean Hamada grade of 1.7 (SD 0.5) at final follow-up, the rate of progression of cuff tear arthropathy remained low-grade. Comparison between the isolated SSC and combined SSC and reparable supraspinatus tear groups showed no significant differences. At final follow-up, one patient (3.8%) had undergone revision surgery to a reverse shoulder arthroplasty (RSA). No neurological complications were associated with the procedure. Conclusion: Latissimus dorsi transfer for an irreparable SSC tendon tear resulted in a significant clinical improvement, particularly in pain, range and strength of internal rotation and aROM, which were maintained over a mean of 8.7 years following surgery. Given that this was a long-term outcome study, there was a low-grade progression in the rate of cuff tear arthropathy. Thus, the long-term clinical efficacy of latissimus dorsi tendon transfer in patients with irreparable SSC was confirmed as a joint-preserving procedure for these patients, suggesting it as an effective alternative to RSA in young, active patients without degenerative changes of the glenohumeral joint.

RESUMEN

PURPOSE: To investigate the feasibility and effect of free latissimus dorsi myocutaneous flap in the reconstruction of giant head and neck defects. METHODS: Free latissimus dorsi myocutaneous flap on the cadaver was simulated dissected, and measured by Image-Pro Plus 6.0 to assess the feasibility of repairing giant head and neck defects. Between May 2011 and September 2022, seven patients with giant head and neck defects of different causes repaired with the latissimus dorsi myocutaneous flap were retrospectively analyzed. RESULTS: The diameter of the initiating thoracodorsal artery was (4.03±0.56) mm, and the mean lengths of the arteriolar and venous pedicles of the latissimus dorsi myocutaneous flaps obtained from human specimens were (85.5±10.5) mm and (104±4.2) mm, respectively. Among 7 patients, 5 cases had scalp defects, the remaining 2 cases had neck defects. There were no substantial postoperative problems in the donor site, and all seven latissimus dorsi myocutaneous flaps were successfully transplanted. CONCLUSIONS: For the treatment of considerable head and neck deformities, the latissimus dorsi myocutaneous flap is an optimal muscle flap due to its abundance of tissue, enough length of vascular pedicles, and sufficient venous drainage.

RESUMEN

BACKGROUND: Latissimus Dorsi (LD) flap is at present among the best techniques for autologous breast reconstruction. A reliable pre-operatory estimation of flap volume would enhance surgical planning, thus improving the aesthetic outcomes of the reconstruction and reducing the need of secondary revision procedures. The study was aimed at providing a simple and reproducible formula to predict LD flap volume pre-operatively. METHODS: 61 patients (66 flaps) who underwent breast reconstruction with LD flap at Policlinico Tor Vergata were prospectively enroled in the study. Anthropometric data and flap measurements were collected pre-operatively. LD flap volume was determined intraoperatively utilising a water displacement technique. A multivariate regression analysis was performed to analyse the collected data and to obtain the mathematical model that most accurately predicts flap volume. RESULTS: The mean actual LD flap volume calculated through water displacement was 213.14 cc (SD 64.56). Performing a multivariate regression analysis BMI and skin paddle width emerged as the most accurate predictors of Latissimus Dorsi flap volume. The mean predicted LD flap volume (LD-V) using the LD-V formula was 213.19 cc (SD 54.59), with a strong Pearson correlation (r = 0.845; R2 =0.715) with the volume calculated through the water displacement technique. CONCLUSIONS: The LD-V formula is an easy and reliable tool for LD flap volume assessment, available as 3.0 WebApp at www.braflap.com, that can be used as a valuable adjunct to surgeon's subjective evaluation to optimise breast reconstruction with the LD flap. LEVEL OF EVIDENCE: II.

RESUMEN

Objective: To investigate the benefits and drawbacks of breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer and treatment experience of postoperative operation-related complications. Methods: A retrospective analysis was performed on clinical data of 26 female patients with breast cancer who met the selection criteria between September 2021 and March 2023 aging 48.7 years (range, 26-69 years). All tumors were unilateral, with 17 on the left side and 9 on the right side. The tumor size ranged from 1.0 to 7.0 cm, with an average of 2.7 cm. The pathological staging included T 1 in 11 cases, T 2 in 14 cases, and T 3 in 1 case; N 0 in 10 cases, N 1 in 11 cases, N 2 in 2 cases, and N 3 in 3 cases; no distant metastasis (M 0) occurred when first diagnosed. Among them, 10 cases underwent breast conserving surgery, and 16 cases underwent nipple-sparing mastectomy. All patients underwent breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap. The operation time, incision length, and postoperative drainage volume in 3 days were recorded. Breast-Q "Satisfaction with back" scale was conducted to evaluate patients' satisfaction with back at 6 months after operation. Results: The operation time was 280-480 minutes (mean, 376.7 minutes), the incision length was 10-15 cm (mean, 12.2 cm), the postoperative drainage volume in 3 days was 500-1 600 mL (mean, 930.2 mL). There were 4 cases of postoperative seroma, 1 case of incision rupture, 1 case of paresthesia of the thoracic wall, and 1 case of edema of the ipsilateral upper limb. All patients were followed up 12-30 months (mean, 20.1 months). No latissimus dorsi muscle flap necrosis, latissimus dorsi muscle atrophy, or shoulder joint dysfunction occurred during follow-up; 2 patients had recurrence of lymph nodes in the ipsilateral axilla after operation, but no distant metastasis occurred. Breast-Q score at 6 months after operation was 64-100 (mean, 79.5). The average score was 78.6 (range, 64-100) in patients underwent nipple-sparing mastectomy and 81.0 (range, 78-100) in patients underwent breast conserving surgery. Conclusion: Breast reconstruction with endoscopic-assisted harvesting of the latissimus dorsi muscle flap for breast cancer is proven to be a surgical approach with safety and cosmetic effects with mild postoperative operation-related complications and considerable patient satisfaction.

RESUMEN

Breast reconstruction is an integral part of breast cancer management. Conventional techniques of flap harvesting for autologous breast reconstruction are associated with considerable complications. Robotic surgery has enabled a new spectrum of minimally invasive breast surgeries. The current systematic review and meta-analysis study was designed to retrieve the surgical and clinical outcomes of robotic versus conventional techniques for autologous breast reconstruction. An extensive systematic literature review was performed from inception to 25 April 2023. All clinical studies comparing the outcomes of robotic and conventional autologous breast reconstruction were included for meta-analysis. The present meta-analysis included seven articles consisting of 783 patients. Of them, 263 patients received robotic breast reconstruction, while 520 patients received conventional technique. Of note, 477 patients received latissimus dorsi flap (LDF) and 306 were subjected to deep inferior epigastric artery perforator (DIEP) flap. There was a significantly prolonged duration of surgery (MD 58.36;95% CI 32.05,84.67;P < 0.001) and duration of anaesthesia (MD 47;95% CI 16.23,77.77;P = 0.003) among patients who underwent robotic surgery. There was a similar risk of complications between robotic and conventional surgeries. The mean level of pain intensity was significantly lower among patients who received robotic breast surgery (MD- 0.28;95% CI - 0.73,0.17; P = 0.22). There was prolonged length of hospitalization among patients with conventional DIEP flap surgery (MD- 0.59;95% CI - 1.13,- 0.05;P = 0.03). The present meta-analysis highlighted the feasibility, safety, and effectiveness of robotic autologous breast reconstruction. This included the successful harvesting of LDF and DIEP flap with acceptable surgical and functional outcomes.

RESUMEN

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

RESUMEN

BACKGROUND: Chest-wall sarcomas are treated with extensive resections and complex defect reconstruction to restore chest-wall integrity. It is a difficult surgical procedure that incorporates a multidisciplinary approach for the best outcome, preventing paradoxical chest movement issues and reducing complications. OBJECTIVE: We aimed to describe our experience of chest-wall reconstruction using polypropylene mesh (Marlex® Mesh) combined with methyl-methacrylate and soft-tissue coverage with a latissimus dorsi flap following sarcoma resection. PATIENTS AND METHODS: Among the 53 patients treated for primary chest-wall sarcomas at the European Institute of Oncology (IEO) in Milan, Italy, from 1998 to 2020, 14 cases underwent chest-wall resection and reconstruction using polypropylene mesh, methyl-methacrylate and the latissimus dorsi flap. Patients with locally advanced breast cancers, locally advanced lung cancers, squamous cell carcinomas, and other secondary chest-wall malignancies were excluded from the study, as were the patients with different types of chest-wall reconstruction. RESULTS: In this study, 14 patients (6 men and 8 women) with various primary chest-wall sarcomas were enrolled. On an average, 2 ribs (range: 1-5) were removed during the surgeries, and the chest-wall defects ranged from 20 to 150 cm2 with an average size of 73 cm2. The mean follow-up period for these patients was approximately 63.80 months CONCLUSION: The combination of Marlex® mesh filled with methyl-methacrylate and covered using latissimus dorsi myocutaneous flap provides safe, low-cost and effective single-stage chest-wall reconstruction after surgery for primary sarcomas.

RESUMEN

BACKGROUND: About 30% to 50% of women with breast cancer undergo mastectomy, and approximately 50% of them will receive adjuvant radiotherapy (ART). This study evaluates the medium- and long-term impact of ART after immediate breast reconstruction (IBR) with latissimus dorsi myocutaneous (LDM) flap and silicone implants. METHODS: Clinical, surgical, and oncological data were retrospectively collected and analyzed based on the medical records of 176 patients who had undergone IBR with LDM flap and silicone implants. RESULTS: The data showed that 7.4% of patients had a history of previous radiotherapy, 56.3% received ART, 31.8% developed capsular contracture with a mean follow-up of 58.1 months, and 14.2% of surgeries were categorized as procedures with a prolonged operating time, lasting above 1 SD of the observed mean. Those who experienced prolonged operating time (odds ratio, 4.72; 95% confidence interval, 1.72-12.93; P = 0.003) and those who received ART (odds ratio, 7.38; 95% confidence interval, 3.18-17.10; P < 0.001) were more likely to develop capsular contracture. Thirty-two patients (18%) underwent capsulectomy with implant replacement, and 7 patients (4%) had the implant removed. The mean time between IBR and reoperation was 29.1 months. Patients who received ART were 2.84 times more likely to experience reconstruction failure or undergo implant-related reoperation ( P = 0.002). CONCLUSIONS: The results indicated that IBR with LDM flap and silicone implant followed by ART is a safe procedure, resulting in low rates of reconstruction failure. However, ART increased the likelihood of capsular contracture development and implant-related reoperation, having a negative effect on reconstructed breasts.

RESUMEN

BACKGROUND: This study presents preliminary results of robot-assisted nipple-sparing immediate breast reconstruction (R-NSMIBR) with gel implant combined with latissimus dorsi muscle flap without island flap and validation of the safety and utility of this novel surgical modality. METHODS: Records pertinent to R-NSMIBR with gel implants combined with latissimus dorsi muscle flap surgery for breast reconstruction between September 2022 and May 2023 were examined. A total of 13 patients who underwent R-NSMIBR were analyzed, nine of which were performed without skin island. RESULTS: We divided the patients with and without skin islands into two groups and recorded the operation time and bleeding respectively. The mean total operative time for R-NSMIBR was 436.5±56.88 minutes and 355.75±69.68 minutes. As experience in learning increased, time required to create the operating space and position the robotic arm decreased significantly. Not creating an island of skin also saves a great deal of surgical time. Average total blood loss was 37.5±6.45 mL and 26.25±7.5 mL. No cases of nipple-areolar complex necrosis or perioperative complications or no local recurrences were reported. There were no local recurrences or deaths that occurred during a mean follow-up period of 3±1 months. CONCLUSIONS: All the patients expressed satisfaction with the aesthetic outcome following surgery. There were no significant differences between two groups. This surgical method shows promise for future promotion in the field.

RESUMEN

INTRODUCTION: Immediate breast reconstruction following mastectomy reduces perceptions of mutilation and femininity issues in oncological patients, but surgical complications should not delay chemotherapy. This study evaluated postsurgical complications in patients who underwent radical breast surgery followed by immediate reconstruction with latissimus dorsi myocutaneous flaps and silicone implants, along with resulting impacts in delaying chemotherapy. MATERIALS AND METHODS: This retrospective study utilized a prospectively maintained database. Clinical, surgical, and oncological data from 196 women were collected according to the operated side. Patients were grouped according to the time elapsed between surgery and the first cycle of adjuvant chemotherapy: ≤ 60 days (group 1), 61 to 90 days (group 2), or > 90 days (group 3). RESULTS: A total of 198 immediate reconstructions were performed on 196 patients between August 1, 2010 and March 31, 2020; after surgery, 47.4% had minor complications and 7.1% had major complications. Ninety-six patients (48.5%) received adjuvant chemotherapy. The mean time elapsed between surgery and the first chemotherapy cycle was 65.4 days (median: 59), with 52.7% of the patients assigned to group 1, 37.4% to group 2, and 9.9% to group 3. The occurrence of major postoperative complications significantly affected the start of chemotherapy (64.0 vs. 94.5 days; P = .044). Additionally, patients with 2 or more comorbidities were more likely to experience major complications (OR: 3.35; 95% CI: 1.03-10.95; P = .045) than those with 1 or 0. CONCLUSION: Major postoperative complications significantly delayed initiation of adjuvant chemotherapy in oncological patients who underwent radical breast surgery followed by immediate reconstruction with a latissimus dorsi myocutaneous flap and silicone implants.

RESUMEN

BACKGROUND: Although numerous treatments exist for the management of rectovaginal fistula, none has demonstrated its superiority. The role of diverting stoma remains controversial. A few series include Martius flap in the armamentarium. OBJECTIVE: Determine the role of gracilis muscle interposition and Martius flap in the surgical management of rectovaginal fistula. DESIGN: Retrospective cohort study of a pooled prospectively maintained database from 3 centers. PATIENTS: All consecutive eligible patients with rectovaginal fistula undergoing Martius flap and gracilis muscle interposition were included from 2001 to 2022. MAIN OUTCOME MEASURES: Success was defined by the absence of stoma and rectovaginal fistula. RESULTS: Sixty-two patients were included with 55 Martius flap and 24 gracilis muscle interposition performed after failures of 164 initial procedures. Total length of stay was longer for gracilis muscle interposition by 2 days ( p = 0.01) without a significant difference in severe morbidity (20% vs 12%, p = 0.53). Twenty-seven percent of the Martius flap interpositions were performed without a stoma, which did not have an impact on overall morbidity ( p = 0.763). Per patient immediate success rates were not significantly different between groups (35% vs 31%, p > 0.99). The success of gracilis muscle interposition after the failure of the Martius flap was not significantly different from an initial gracilis muscle interposition ( p > 0.99). After simple perineal procedures, the immediate success rate rose to 49.4% (49% vs 50%, p > 0.99). After a median follow-up of 23 months, no significant difference was detected in success rate between the 2 procedures (69% vs 69%, p > 0.99). Smoking was the only negative predictive factor ( p = 0.02). LIMITATIONS: By its retrospective nature, this study is limited in its comparison. CONCLUSIONS: This novel comparison between Martius flap and gracilis muscle interposition suggests that Martius flap presents several advantages, including shorter length of stay, similar morbidity, and similar success rate. Proximal diversion via a stoma for Martius flap does not appear mandatory. Gracilis muscle interposition could be reserved as a salvage procedure after Martius flap failure. See Video Abstract . FSTULA RECTOVAGINAL CUL ES EL ROL DEL COLGAJO DE MARTIUS Y LA INTERPOSICIN DEL MSCULO GRACILIS EN LA ESTRATEGIA TERAPUTICA: ANTECEDENTES:Si bien existen numerosos tratamientos para el manejo de la fistula rectovaginal, ninguno ha demostrado su superioridad. El papel del estoma de derivación sigue siendo controvertido. Pocas series incluyen colgajo de Martius en el armamento.OBJETIVO:Determinar el rol de la interposición del músculo gracilis y del colgajo de Martius, en el manejo quirúrgico de la fístula rectovaginal.DISEÑO:Estudio de cohorte retrospectivo de una base de datos mantenida prospectivamente en 3 centros.AJUSTES/PACIENTES:Se incluyeron todos los pacientes elegibles consecutivos con fistula rectovaginal sometidos a colgajo de Martius y la interposición del músculo gracilis desde 2001 hasta 2022.RESULTADOS PRINCIPALES:El éxito se definió por la ausencia de estoma y fistula rectovaginal.RESULTADOS:Se incluyeron 62 pacientes con 55 colgajo de Martius y 24 con interposición del músculo gracilis realizados después de fracasos de 164 procedimientos iniciales. La duración total de la estancia hospitalaria fue dos días más larga para la interposición del músculo gracilis ( p = 0,01) sin una diferencia significativa en la morbilidad grave (20% frente a 12%, p = 0,53). El 27% de los colgajos de Martius se realizaron sin estoma, sin impacto en la morbilidad global ( p = 0,763). Las tasas de éxito inmediato por paciente no fueron significativamente diferentes entre los grupos (35% vs. 31%, p = 1,0). El éxito de la interposición del músculo gracilis después del fracaso del colgajo de Martius no fue significativamente diferente de una interposición del músculo gracilis inicial (p = 1,0). La tasa de éxito inmediato aumentó al 49,4% (49% frente a 50%, p = 1,0) después de procedimientos perineales simples. Después de una mediana de seguimiento de 23 meses, no se detectaron diferencias significativas en la tasa de éxito entre los dos procedimientos (69 % frente a 69 %, p = 1,0). El tabaquismo fue el único factor predictivo negativo ( p = 0,02).LIMITACIONES:Por su naturaleza retrospectiva, este estudio tiene limitaciones en su comparación.CONCLUSIÓN:Esta novedosa comparación entre colgajo de Martius y la interposición del músculo gracilis sugiere que el colgajo de Martius presenta varias ventajas, incluida una estancia prolongada más corta, una morbilidad similar y un éxito. La derivación proximal a través de un estoma para el colgajo de Martius no parece obligatoria. La interposición del músculo gracilis podría reservarse como procedimiento de rescate después de una falla de colgajo de Martius. (Traducción-Dr. Aurian Garcia Gonzalez ).

RESUMEN

BACKGROUND: Reverse shoulder arthroplasty (RSA) with concurrent latissimus dorsi transfer (LDT) is a potential treatment option for restoration of external rotation (ER). Biomechanical studies have emphasized the importance of the insertion site location for achieving optimal outcomes. In this systematic review and meta-analysis, we aimed to describe what insertion sites for LDT are utilized during concomitant RSA and their associated clinical outcomes. METHODS: A systematic review and meta-analysis were performed per PRISMA guidelines. We queried PubMed/MEDLINE, Embase, Web of Science, and Cochrane databases to identify articles reporting on patients who received RSA with LDT to restore ER and specified the site of tendon transfer insertion on the humerus. We first describe reported insertion sites in the literature. Secondarily, we present preoperative and postoperative range of motion and Constant score for different insertion sites as well as reported complications. RESULTS: Sixteen studies, analyzed as 19 separate cohorts (by insertion site and tendon-transfer), reporting on 264 RSAs with LDT (weighted mean age 66 years, follow-up 39 months, 61% female) were evaluated. Of these, 143 (54%) included a concomitant teres major transfer (LDT/TMT) and 121 (46%) were LDT-only. Fourteen cohorts (14/19, 74%) reported insertion at the posterolateral aspect of the greater tuberosity, four cohorts (4/19, 21%) reported insertion site at the lateral bicipital groove, and one cohort (1/19, 5%) reported separate LDT and TMT with insertion of the TMT to the posterolateral aspect of the greater tuberosity and LDT to the lateral bicipital groove. Meta-analysis revealed no differences in range of motion or Constant score based on humeral insertion site or whether the LDT was transferred alone or with TMT. Leading complications included dislocation, followed by infection and neuropraxia. No discernible correlation was observed between postoperative outcomes and the strategies employed for tendon transfer, prosthesis design, or subscapularis management. CONCLUSION: The posterolateral aspect of the greater tuberosity was the most-utilized insertion site for LDT performed with RSA. However, in the current clinical literature, LDT with or without concomitant TMT result in similar postoperative ROM and Constant score regardless of insertion site. Analysis of various proposed transfer sites reinforce the ability of LDT with RSA to restore both FE and ER in patients with preoperative active elevation and external rotation loss. Meta-analysis revealed significant improvements in range of motion and Constant score regardless of humeral insertion site or whether the LDT was transferred alone or with TMT, although future studies are needed to determine whether an ideal tendon transfer technique exists. LEVEL OF EVIDENCE: IV.

RESUMEN

BACKGROUND: Superior capsular reconstruction (SCR) and lower trapezius tendon transfer (LTT) have recently been used to manage irreparable posterosuperior rotator cuff tears (PSRCTs). There has been a paucity of comparative biomechanical considerations between the 2 procedures. PURPOSE: To compare the glenohumeral stability and biomechanical properties between SCR and LTT in PSRCTs involving the entire infraspinatus tendon region. STUDY DESIGN: Controlled laboratory study. METHODS: Eight fresh-frozen cadaveric shoulders were tested at 0°, 20°, and 40° of shoulder abduction. Maximum internal, external, and total humeral range of motion (ROM), superior translation of the humeral head, and subacromial contact characteristics were compared among 4 conditions: (1) intact rotator cuff, (2) PSRCTs involving the entire infraspinatus tendon region, (3) LTT using Achilles allograft (12 N and 24 N of loading), and (4) SCR using fascia lata allograft. RESULTS: Although a decrease in total ROM was noted in LTT with 12 N compared with the tear condition, LTT with both 12 N and 24 N as well as SCR did not restrict total rotational ROM compared with the intact condition. LTT had decreased total ROM compared with tear condition at 20° of abduction (P = .042), while no significant decrease was confirmed at all abduction angles after SCR. SCR and LTT with 24 N decreased superior translation compared with the PSRCT condition at 0° and 20° of abduction (P < .037) but not significantly at 40° of abduction, whereas LTT with a 24-N load decreased glenohumeral superior translation at all abduction angles (P < .039). Both SCR and LTT decreased subacromial contact pressure compared with the tear condition (P < .014) at all abduction angles. SCR decreased subacromial contact pressure at 0° and 40° of abduction (P = .019 and P = .048, respectively) compared with LTT with 12 N of loading, while there was no difference between SCR and LTT with 24 N of loading in all abduction angles. SCR increased the contact area compared with the PSRCT condition at all abduction angles (P < .023), whereas LTT did not increase the contact area. CONCLUSION: SCR and LTT decreased glenohumeral superior translation and contact pressure compared with PSRCT conditions. The LTT was superior to SCR in terms of superior translation of the humeral head at a higher shoulder abduction angle, whereas the SCR showed more advantageous subacromial contact characteristics compared with LTT. CLINICAL RELEVANCE: These biomechanical findings provide insights into these 2 fundamentally different procedures for the treatment of young and active patients with PSRCTs involving the entire infraspinatus tendon region.

RESUMEN

BACKGROUND: Partial or total laryngopharyngectomy defects have traditionally been reconstructed using the radial forearm, anterolateral thigh, or jejunal free flaps. The latissimus dorsi myocutaneous free flap (LDMFF) is an option for high-risk patients with complex laryngopharyngeal ± cutaneous neck defects. METHODS: Retrospective single-surgeon case series from 2017 to 2022. Outcomes were assessed at both the back donor site and head and neck. RESULTS: Twenty-four patients were identified. Flap survival was 100%. There was 1 (4.2%) pharyngocutaneous fistula and 2 (8.3%) tracheo-esophageal peristomal fistulas. At last follow-up, 17 (71%) were sustaining weight on oral intake, and 7 (29%) were G-tube dependent with 4 of these able to do some type of oral intake. Seven (29.2%) had post-operative stricture/stenosis requiring dilation. There were only minor donor site complications, all managed conservatively. CONCLUSIONS: The LDMFF can be a robust reconstructive option, particularly for radiated high-risk patients with complex pharyngeal defects, including skin.

RESUMEN

A desmoid tumour, also known as aggressive fibrous tumour or desmoid fibromatosis, is a rare, benign tumour originating from connective tissue cells. Desmoid tumours account for approximately 0.03+% of all neoplasms and less than 3+% of all soft tissue tumours. The estimated incidence in the general population is 2 to 4 cases per million people per year [1]. Desmoid tumours are characterised by aggressive growth but typically do not metastasize. They often occur in young adults and preferably affect specific body regions such as the abdomen, shoulder, chest, or extremities. The exact cause of the condition is not fully understood, but genetic changes and hormonal factors may play a role. Symptoms of a desmoid tumour depend on its location and size, with pain, swelling, or restricted movement commonly occurring. A diagnosis is typically made through a tissue sample (biopsy) and imaging techniques such as MRI or CT [2]. To our knowledge, this is the first documented case of recurrence of a desmoid tumour in the scar at the donor site of a latissimus dorsi flap previously used for the reconstruction of desmoid resection in the lower leg.

RESUMEN

BACKGROUND: The fat-augmented latissimus dorsi (FALD) flap is an evolution of the traditional latissimus dorsi (LD) flap, which allows to obtain a total autologous breast reconstruction (BR) avoiding the use of breast implants. The aim of this study was to develop a predictive preoperative formula in order to estimate and optimize the amount of fat to be transferred during FALD flap BR, using only anthropometric measurements. METHODS: We conducted a prospective clinical study between September 2020 and April 2023. All patients underwent back pre-operative ultrasound scan to assess the subcutaneous skin paddle thickness (SPT) and a regression analysis was performed to evaluate which anthropometric variable had a better correlation with this thickness. RESULTS: Data from 66 FALD flaps were collected. The mean SPT was 11.95 mm (SD 4.56). A significant correlation between SPT and body mass index (BMI) was found (r = 0.640, p < 0.0001). Using the fat-to-capacity ratio (113%), the following formula (the FALD-V) was developed to predict the needed fat transfer into FALD flap: [-509 + 12.32 × BMI + 11.71 × skin paddle width + 17.43 × skin paddle height] × 1.13. The considered variables (BMI, skin paddle width and skin paddle height) were statistically significant (p < 0.001, p = 0.0483, p = 0.0154, respectively). The cross-validation confirmed the accuracy of the formula (r = 0.810). CONCLUSION: The FALD-V can be used as an innovative complimentary device in the planning of FALD flap one-stage total autologous BR. To enhance its application, a 3.0 WebApp at www.braflap.com (and www.breast-v.com) is available free of charge for both iOS and Android devices. LEVEL OF EVIDENCE: II.
