RESUMEN

The purpose of this study was to report early complications for anatomic total shoulder arthroplasty (aTSA) performed for instability arthropathy after a prior coracoid transfer procedure and compare them with those of a control group of patients following aTSA for primary osteoarthritis. A retrospective review was performed of 14 patients after aTSA with a prior coracoid transfer procedure. A control group of 42 patients with an aTSA for primary osteoarthritis were matched 3:1 according to age, sex, body mass index, comorbidities, and dominant shoulder. Chart reviews identified any complications within 1 year, in addition to blood loss and operative time in both groups. Preoperative computed tomography scans were used to determine Walch glenoid classification and Goutallier classification of the subscapularis. The mean operative time was not significantly different between the coracoid transfer cohort and the control group, and the mean estimated blood loss was only 6.9 mL greater in the coracoid transfer group. The coracoid transfer group had 2 (14.3%) patients with complications, with 1 early revision for an acute deep infection. The control group had 4 (9.5%) complications in 3 (7.1%) patients, with no early revisions. There was no statistical difference in complications between the groups (P=.618). Anatomic TSA for instability arthropathy after coracoid transfer had similar operative time, blood loss, and 1-year complication rates as those of the control group. These results provide some evidence to support the continued use of aTSA in select patients with instability arthropathy after prior coracoid transfer procedure.

RESUMEN

Most arthroscopic techniques provide easy invasive access and subsequent inspection of the lateral segments of the hip joint. However, it is a challenge to visualize medial segments of the hip joint using arthroscopic techniques. Hip arthroscopy offers minimally invasive access to the hip joint as compared to the standard open arthrotomy procedure. Yet, visualization of both the femoral head and acetabulum is difficult. The use of arthroscopic techniques in the diagnosis and treatment of hip-related disorders is still evolving, including great benefits for the postoperative healing and complications. The author describes a case of removing two loose bodies stuck in the superior basicervical rim of the femoral head of a 53-year-old man. The use of the inferomedial arthroscopic technique proved advantageous in preventing the shortcomings associated with standard arthrotomy and other arthroscopic mechanisms. Such shortcomings include the need for traction, alternate portals, and damage to the acetabular labrum and articular cartilage. Through this case report, the author establishes the effective use of hip arthroscopy in the removal of two loose bodies from the hip joint.

RESUMEN

Transfusion-related acute lung injury (TRALI) is a clinical syndrome characterized by acute respiratory distress following blood transfusion. This case-based technical report documents a case on the management of a multi-level forearm microsurgical reconstruction and the following TRALI syndrome that developed shortly after blood transfusion in a 29-year-old male. Multilevel microsurgical revascularization was performed via saphenous vein autograft arterial reconstruction from the proximal 1/3 ulnar artery to the ulnar side of the deep superficial palmar arterial arch. TRALI was resolved with intensive care unit monitoring and treatment. There are several reports of TRALI in literature, as well as proposed mechanisms of pathogenesis, however, no case on the management of a multilevel forearm arterial reconstruction via a long saphenous vein autograft and associated TRALI syndrome have been reported.

RESUMEN

OBJECTIVE: This study aimed to determine, pre-correction, the potential change in the osteotomy-site bony contact surface area that would occur during standard metatarsal diaphyseal procedures with the Baran-Unal modification of Mau osteotomy and then to compare it, post-correction, with the actual osteotomy-site bony contact surface area changes for a standard degree of deformity correction. METHODS: A total of 30 standard, same sized, biomechanically equivalent, left first metatarsal sawbones were included in this experimental study. They were divided equally into five groups for each of the planned osteotomy techniques: Myerson's modification of Ludloff, Mau, scarf, Offset V, and Baran-Unal modification of Mau osteotomy. The normal osteotomy for each sample was considered as the control, while the corrective osteotomy was the test. Computerized tomography scans and three-dimensional (3D) reconstruction imaging were performed for objective and accurate measurements. The techniques of the osteotomy and post-corrective osteotomy bony contact surface areas were investigated by the two independent research assistants. RESULTS: There was a statistically significant difference between the contact surface area changes of all pre- and post-corrective osteotomy groups (P<0.05). When the pre- and post-correction contact surface areas of any one group were compared with the other groups, the differences were or were not statistically significant. Mean differences between pre-correction and post-correction areas for Ludloff, Mau, scarf, Offset V, and Baran-Unal osteotomies were 180.7, 122.3, 226.2, 191.9, and 68.9 mm2, and the percentages of area loss were 22.9%, 15.5%, 28.6%, 24.3%, and 8.7%, respectively. The most bony contact area was found in the scarf osteotomy group (mean pre-correction area: 490.5 mm2 and mean post-correction area: 264.3 mm2), but the Baran-Unal modification group has significantly the highest post-correction bony contact area among the all other groups (mean pre-correction area: 413.3 mm2 and mean post-correction area: 344.4 mm2). CONCLUSION: Metatarsal diaphyseal osteotomies for hallux valgus deformity have the potential not only for deformity correction, but also for contact surface area preservation. This study reaffirms the considerable potential of this new Baran-Unal modification to confer outstanding contact surface area values, even with the operative correction of hallux valgus deformity.

RESUMEN

AIM: The aim of this study was to derive a pure, unbiased, reliable and accurate objective relationship between the local knee axis measurements through a short knee anteroposterior roentgenogram and the lower limb axis measurement through an orthoroentgenogram. PATIENTS AND METHODS: Radiographs of 114 patients (114 knees) were evaluated by two independent raters for measurement of lower limb axis on an orthoroentgenogram and the local knee axis on short knee anteroposterior X-ray, which was derived by cropping the orthoroentgenogram by a blinded radiology assistant. The raters measured at two different time-points separated by an interval of 30-day period. Intra-rater and inter-rater reliabilities were calculated by intra-class correlation coefficients and three models were built to establish the relationships of X-ray anatomical axis with orthoroentgenogram anatomical axis, orthoroentgenogram anatomical axis with orthoroentgenogram mechanical axis and X-ray anatomical axis with orthoroentgenogram mechanical axis. RESULTS: For three different measurements, intra-class correlation coefficients of Rater 2 were higher than 0.90 which shows perfect reliability, while that for Rater 1 was low. Furthermore, first measurements were more consistent than the second measurement. There was a strong positive correlation in all the three models except for varus cases in the last. CONCLUSION: The standardized correlation derived between the two different techniques for measuring knee alignment is fairly comparable with the studies in the past and would serve as a reliable template for future studies concerning relationships between the two, in addition to helping knee surgeons make more reliable and accurate interpretations through local knee axis measurements.

RESUMEN

BACKGROUND: Many surgeons are concerned about reports of increased complications, worse outcomes, and early failures in patients undergoing anatomic total shoulder arthroplasty after coracoid transfer. The purpose of this study was to evaluate minimum 2-year outcomes following anatomic total shoulder arthroplasty for instability arthropathy with a prior coracoid transfer procedure and compare them with a matched cohort of patients undergoing total shoulder arthroplasty for primary osteoarthritis. METHODS: We identified 11 primary anatomic total shoulder arthroplasties performed by a single surgeon for instability arthropathy with a prior coracoid transfer procedure with a minimum of 2 years' follow-up (mean, 58 ± 35 months). A matched cohort of 33 patients with a total shoulder arthroplasty for primary osteoarthritis served as the control group. The American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numeric Evaluation (SANE) score, patient satisfaction, complications, and revisions were evaluated in both cohorts. RESULTS: The coracoid transfer cohort showed no difference in the final ASES score (88 vs. 82, P = .166) or SANE score (85 vs. 67, P = .120) vs. the matched cohort. The postoperative ASES pain score (45 vs. 41, P = .004) was higher in the coracoid transfer cohort, but the mean improvement from preoperative to postoperative values for the ASES score (P = .954), ASES pain score (P = .183), and SANE score (P = .293) was no different between cohorts. Both cohorts had high patient satisfaction without a statistically significant difference (P = .784). CONCLUSION: At early- to mid-term follow-up, total shoulder arthroplasty performed after a coracoid transfer demonstrated similar results to total shoulder arthroplasty performed for primary osteoarthritis. Longer follow-up and larger patient cohorts will provide further insights and highlight any potential differences in outcomes or revision rates.

RESUMEN

STUDY DESIGN: Retrospective cohort study. INTRODUCTION: A new method of accurately assessing the compromised elbow's proprioception was developed for this postsurgical population using information from previous neurophysiologic proprioception studies of healthy elbows. HYPOTHESIS: This retrospective cohort study investigated the patterns and the degree of proprioceptive impairment and recovery following arthroscopic surgery for chronic lateral epicondylitis. MATERIAL AND METHODS: Participants had undergone arthroscopic elbow surgery two years prior to this study (n=15). Healthy, non-injured volunteers with similar demographics (n=15) served as controls. Both groups were evaluated using quantitative measures of joint position sense for proprioceptive functioning. In order to obtain the most accurate proprioceptive measurements, interindividual interaction and visual input biases were eliminated. Retrospective chart reviews were performed to compare qualitative self-reported measures of proprioceptive function in arthroscopic surgery patients before surgery and two years post-surgery. RESULTS: Active and passive joint repositioning outcome measurements were similar between groups (p>0.05). No significant differences were found among any angles except one: passive joint position sense at 120° of flexion (p<0.05). At this angle, the arthroscopy group showed greater deviation from target angles than the control group. The novel proprioceptive testing method we developed was found to be accurate and reliable. DISCUSSION: Outcomes of arthroscopic treatment of chronic lateral epicondylitis with no decortication yielded outcomes measure similar to those of healthy controls. The sole significant difference was at 120° flexion passive joint repositioning, with a higher negative angular deviation from the target point. We propose that our study results and specific proprioception method may have implications for improving accuracy of future elbow arthroscopy and proprioceptive recovery in this population. LEVEL OF EVIDENCE: II, low-powered prospective randomized trial.

RESUMEN

Residual foreign bodies are usually observed inside the body after foreign body penetration injuries. However, foreign bodies inside or near the joints are rarely encountered. In the case study included in this report, the case of a foreign body in the posterior ankle region of a 10-year-old child is presented, along with a new study highlighting the technique of its excision with hindfoot endoscopy. The visualization and capture of a foreign body within this region, and its relation to endoscopic excision, has been reported as being a support for hindfoot endoscopy. The aim of this article is to highlight the need for the provision of a low threshold arthroscopic hindfoot surgery in children who display the appropriate symptoms. The purpose of this surgery is to efficiently remove intra-articular hindfoot loose bodies and to gain functionally improved results, when compared with open techniques.

RESUMEN

BACKGROUND: Few studies have investigated clinical and structural outcomes after transosseous (TO) repair. The purpose of this study was to compare structural and clinical outcomes of rotator cuff tear, repaired arthroscopically, with a single row (SR) or transossoeus (TO) anchorless technique. METHODS: 96 patients who underwent an arthroscopic repair for superior or posterosuperior rotator cuff tear using TO (n:54) or a SR (n:42) were retrospectively enrolled in this study after evaluation of clinical and surgical notes. Functional evaluation was performed with the adjusted Constant score, and American Shoulder and Elbow Surgeons (ASES) score. Postoperative cuff integrity was determined through MRI study. RESULTS: Patients were recalled after a minimum follow-up of two years. All the patients were available for the study. In the SR group the Constant rating system showed a significant improvement from a preoperative average rating of 44.8 to an average of 85.7. In the group of TO repair the Constant rating system showed a significant improvement from a preoperative average of 46.1 to an average of 87.6 postoperatively. According to ASES index scores, the average total score improved from 42.8 to 92.0 in the anchor group and from 40.4 to 94.6 in the TO group. There was no statistical difference between the two groups about clinical outcomes. Postoperative MRI revealed no differences in term of complete re-tears between the two techniques. In the SR group at MRI we observe significant more cases of rotator cuff with a Sugaya type III healing. CONCLUSIONS: Arthroscopic rotator cuff repair yielded successful clinical outcomes using SR and TO technique. However using the TO technique we saw less type 3 Sugaya readings on MRI suggesting a possible benefit with TO repair. LEVEL OF EVIDENCE II: Retrospective study.

RESUMEN

Objectives Bursitis of the olecranon and the patella are not rare disorders, and conservative management is successful in most cases. However, when patients do not respond to conservative treatment, open excisional surgery or, recently, endoscopic bursectomy, can be used. The aim of this study was to evaluate the results of open and endoscopic treatments of olecranon and prepatellar bursitis. Patients and methods Forty-nine patients (37 male and 12 female), who were treated with endoscopic bursectomy (25 patients) or open bursectomy (24 patients) were included in this study. Thirty patients had olecranon bursitis, while 19 patients had prepatellar bursitis. The patients' average age was 61.1 ± 12.3 (range 33-81) years. All of the patients' hospitalization and surgery times were recorded. The satisfaction of the patients was evaluated with a satisfaction scoring system, as well as by evaluating residual pain, the range of joint movement, and the cosmetic results of the procedure. Results The average follow-up time was 16 ± 9 months (range 12-27). The median operation time was 23.2 ± 3.5 minutes for the endoscopic bursectomy group and 26.4 ± 6.8 minutes for the open bursectomy group. The median hospitalization time was 0.56 ± 0.5 days (range 0-1 day) for the endoscopic group and 1 ± 0 days for the open bursectomy group (P<0.01). According to the patient satisfaction questionnaire, the endoscopic bursectomy group's score was 8.5 ± 1.3 (range 5-10), and the open bursectomy group's score was 5.29 ± 1.8 (range 1-9) (P<0.01). Conclusion Endoscopic bursectomy is a time-saving and efficient surgical treatment option for patients with prepatellar and olecranon bursitis.

RESUMEN

Compartment syndrome (CS) is a threatening condition characterized by excessive tissue pressure accumulation associated with acute trauma. Compartment syndrome causes a significant reduction in blood flow with subsequent muscle and nerve ischemic necrosis. Recently, reports have described the importance of intramuscular pressure measurements as a basis for CS diagnosis. Unfortunately, the measuring devices that were utilized produced results with unsatisfactory reliability, making a diagnosis and subsequent treatment challenging. Here, we report the use of an anesthesia pressure monitoring device with greater precision for pressure measurements, as well as real-time monitoring of intraoperative compartment pressure decompression efficacy. This device enabled the accurate diagnosis and rapid treatment of a thenar compartment syndrome (TCS) in the left hand of a diabetic female in an emergency setting. She presented extreme pain in the thumb flexion-extension (FE). Her condition was complicated by diabetic cellulitis, primarily of Staphylococcus aureus. Consequently, successful microsurgery in the thenar space, together with debridement, resulted in remarkable pain relief during FE of the thumb metacarpophalangeal (MCP) and interphalangeal (IP) joints, as well as the disappearance of the infection by Day 10. Subsequent one- to two-year follow-up assessments revealed marked recovery.

RESUMEN

INTRODUCTION: Previously, the majority of wars were fought on remote battlefields between opposing armies due to conflicts preventing civilians from sustaining war-related burn injuries (WRBI). In recent years, WRBI has had a tremendous harmful impact on the pediatric population. This study aimed to investigate the demographics, causes, mechanisms of burns, surgical procedures, the major and minor risk factors affecting mortality, and outcomes of pediatric WRBI amidst the Syrian refugees and the Turkey neighborhood population, treated at our Burn Center. METHODS: Out of the 852 filled records, the retrospective cohort was performed with inclusion of 707 pediatric burn patients, 469 Turkey, and 238 Syrian participants, with age 0-17 years. Included in the study were patients admitted to our institution from December 2013 to May 2016, with at least 12 months of consistent follow-up. Independent variables of each patient collected data included age, gender, weight, ethnicity, locations patients coming from, season and reason of burn, type of burn, grade of burn, burnt body regions, total body surface area (TBSA), body surface area (BSA), burnt surface area (BuSA), time delay until admission, and presence of infection at time of admission. The dependent variables were hospitalization periods, surgical procedures of escharotomy, fasciotomy, and grafting, recorded final patient status, and mortality. RESULTS: Syrian children with WRBI (direct-blastic, indirect-unintentional) suffered from higher BSA (mean=0.91m2, p=0.001) than the Turkish children with non-intentional burns (0.89m2, p=0.001), P=0.001. There was a significant relationship between causes of burns, such as hot liquids, fire/flames and blastic injuries among the Syrian (52.9%, 27.3%, p=0.000) and the Turkish (86.4%, 7.6% P=0.000) populations, respectively. Although most of the Turkey residents suffered more from hot liquid burns than the Syrians (86.4% vs 52.9%), the majority of mortality occurred with fire/flames and blastic injuries, which was higher among the Syrians (10.10%, p=0.001) than the Turkish (2.80% p=0.001). Mortality corresponded with complex and third-degree burns, ranking higher in the Syrian (100%) than in the Turkish (23.3%), which, in turn, related to hospital length of stay (Syrian mean: 9.79, p=0.001; Turkish mean: 7.83, p=0.839). CONCLUSION: Our analysis showed that flame/fire and blast burns were severe and fatal in more pediatric Syrian victims than the Turkey residents due to the severity of war inflicted burned wounds, the living conditions at the refugee camps, and the tent cities. Our present study is significant as our data would alert authorities to predict pediatric WRBI risk factors, burn survivals and casualties, and thus plan strategies to promote training programs for burn management of two distinct populations to reduce risk factors of burn mortality. Burnt surface area (BuSA) is a new parameter we derived to predict mortality risk factors in WRBI.

RESUMEN

INTRODUCTION: The purpose of this study was to perform a mid-long-term clinical and radiographic evaluation of the results obtained in patients older than 75 years treated with minimally invasive unicompartmental knee arthroplasty (UKA). The hypothesis was that UKA is a viable solution for the definitive treatment of localized disease in this age group, with good results and a low failure rate. METHODS: An all-poly tibial component UKA was applied with a minimally invasive technique. Sixty-seven knees in patients with a minimum age of 75 years were evaluated at mean 9 years' follow-up. The Oxford knee score, Knee Society Score, WOMAC score, Visual Analogue Scale (VAS) for pain self-assessment and range of motion (ROM) were determined, as well as weight-bearing antero-posterior and laterolateral radiographs. RESULTS: All clinical scores, as well as VAS and ROM, improved significantly at 9-year follow-up, and the outcome was considered good or excellent in 92.6% of the patients. Radiographic results showed that both tibial plateau angle and posterior tibial slope angles were maintained, whereas femoro-tibial angle was significantly changed at follow-up. Further analysis showed no significant correlation between clinical scores and body mass index, whereas the clinical outcome was correlated with the ROM obtained. Only two failures and one major post-operative complication were observed. CONCLUSIONS: UKA is a viable option for treating unicompartmental knee osteoarthritis. With the proper indications and an accurate technique UKA may be indicated also in very elderly patients with reduced complications and morbidity, and excellent survivorship.

RESUMEN

OBJECTIVE: Intramedullary nailing is the preferred surgical treatment of humerus shaft fractures. The purpose of this study was to investigate the relationship between the bicipital groove and specific anatomical landmarks in achieving correct alignment of the humerus during intramedullary nailing, and to describe these anatomical landmarks. METHODS: Thirty (15 right; 15 left) total upper cadaver extremities were used in this study. After the anatomical landmarks were identified and marked, humeral head axis, transepicondylar axis, ulnar shaft axis, bicipital groove axis, and angular measurements of these were obtained. RESULTS: The mean angle between the bicipital groove axis and transepicondylar axis was 48.17°±12.35º (range: 20.10º to 74.6º). The mean angle between the bicipital groove axis and ulna diaphysis axis was 41.82º±11.56 º (range: 17.91º to 68.27º). The mean angle between the humeral head axis and bicipital groove axis was 20.53°±3.90º (range: 11.85º to 31.81º). The mean retroversion angle between the humeral head axis and transepicondylar axis was 27.52±11.37º (range: 4.26º to 49.36º). The mean angle between the humeral head axis and ulna diaphysis axis was 61.73º±12.08º (range: 33.97º to 86.37º). The mean torsion angle was 62.58º±11.28 º (range: 40.74º to 85.74º). CONCLUSION: Measurement and utilization of the relationship between the bicipital groove, ulna diaphysis and transepicondylar axes may be used for restoring humeral rotation.

RESUMEN

BACKGROUND: The aim of this study was to evaluate the biomechanical behavior of anterior inferior tibiofibularis ligament (AITFL) deficient human ankle under axial loading of ankle at stance phase of gait. In order to investigate the contribution of AITFL to ankle stability, an in vitro sequential experimental setup was simulated. METHODS: The measurement of posterior displacement of distal tibia and anterior displacement of the foot, in neutral position, secondary to axial compression, was performed by two non-contact video extensometers. Eight freshly frozen, anatomically intact, cadaveric human ankle specimens were included and tested. An axial compression test machine was utilized from 0 to 800 Newtonswith a loading speed of 5 mm/min in order to simulate the axial weight-bearing sequence of the ankle at stance phase of human gait. RESULTS: There was a statistically significant difference between anteroposterior displacement values for AITFL-Intact and AITFL-Dissected specimens (p≤0.05). Mean AITFL-Intact and mean AITFL-Dissected ankle anteroposterior displacement was 1.28±0.47 mm and 2.06±0.7 mm, respectively. CONCLUSION: This study determined some numerical and quantitative data about the biomechanical properties of AITFL in neutral foot position. In the emergency department, diagnosis and treatment of AITFL injury, due to ankle distortion, is important. In AITFL injuries, ankle biomechanics is affected, and ankle instability occurs.
