RESUMEN
Pure vascularized periosteal transplants have been shown to be extremely effective at achieving rapid bone healing in children with biologically complex non-union. Free tibial and fibular periosteal transplants are generally indicated when large periosteal flaps are necessary. We report using a vascularized femoral myo-periosteal graft (VFMPG) to treat distal tibial osteotomy non-union in a six-year-old boy with congenital pseudarthrosis of the tibia. The graft consisted of a 9 cm myo-periosteal flap (after 50% of elastic retraction) that incorporated the vastus intermedius muscle and diaphyseal femoral periosteum nourished by the descending branch of the lateral circumflex femoral vessels. Plantaris medialis was used as a recipient vessel. Healing occurred 10 weeks after surgery. The patient resumed gait and sports activity without orthosis. No donor or recipient site complications occurred 17 months after surgery. Employing a VFMPG might be an alternative to other free or large vascularized periosteal flaps currently in use for complex pediatric non-unions.

Recurrent posterior shoulder instability after primary repair is uncommon, but presents a challenging clinical scenario. Most revisions in failed labral repair were associated with glenoid bone morphology related to critical bone loss, retroversion, or dysplasia. A variety of treatment options exist which include revision labral repair with or without capsular plication, glenoid osteotomy, humeral rotational osteotomy, or glenoid bone augmentation. No single technique has been shown to be superior and each technique has strengths and limitations. Therefore, thoughtful evaluation and planning is critical to address each patient's individual pathology to maximize success after revision surgery.

A 7 yr old castrated male domestic shorthair presented for assessment of a chronic left head tilt, losses of balance, and positional nystagmus. A computed tomographic scan of the head revealed several fragments of a metallic foreign body in the left tympanic cavity. The foreign material was removed under endoscopic assistance through a minimally invasive ventral bulla osteotomy. No complications were noted during the immediate postoperative period. Follow-up 5 mo after surgery revealed complete resolution of the neurological signs with no evidence of recurrence. Foreign bodies associated with middle ear infection have not been previously reported in the cat. They should now be included in the differential diagnosis of vestibular disease. Endoscopic-assisted foreign body removal in the middle ear seems to be a safe and efficient way to retrieve small foreign bodies in bullae in cats.

The use of a filling block can improve the initial stability of the fixation plate in the open wedge high tibial osteotomy (OWHTO), and promote bone healing. However, the biomechanical effects of filling block structures and materials on OWHTO remain unclear. OWHTO anatomical filling block model was designed and built. The finite element analysis method was adopted to study the influence of six filling block structure designs and four different materials on the stress of the fixed plate, tibia, screw, and filling block, and the micro-displacement at the wedge gap of the OWHTO fixation system. After the filling block was introduced in the OWHTO, the maximum von Mises stress of the fixation plate was reduced by more than 30%, the maximum von Mises stress of the tibia decreased by more than 15%, and the lateral hinge decreased by 81%. When the filling block was designed to be filled in the posterior position of the wedge gap, the maximum von Mises stress of the fixation system was 97.8 MPa, which was smaller than other filling methods. The minimum micro-displacement of osteotomy space was -2.9 µm, which was larger than that of other filling methods. Compared with titanium alloy and tantalum metal materials, porous hydroxyapatite material could obtain larger micro-displacement in the osteotomy cavity, which is conducive to stimulating bone healing. The results demonstrate that OWHTO with a filling block can better balance the stress distribution of the fixation system, and a better fixation effect can be obtained by using a filling block filled in the posterior position. Porous HA used as the material of the filling block can obtain a better bone healing effect.

Structural deformities of the acetabulum secondary to developmental dysplasia of the hip (DDH) are one of the most common causes requiring total hip arthroplasty (THA), whether in conjunction with femoral osteotomy in cases of Crowe dislocation 4. Several techniques have been described, studied, and compared, but there is no superiority of one technique over another. Currently, most hip surgeons perform a subtrochanteric osteotomy. With a follow-up of 10 years, good results have been obtained, so there is a need to present a therapeutic alternative with potential benefits, mainly in restoring the center of rotation of the hip, preserving the proximal bone component, and reducing complications. Therefore, this study aims to describe the surgical technique of CTA in conjunction with supracondylar shortening osteotomy in a 29-year-old female patient, using an uncemented acetabular cup, a short uncemented stem with ceramic-polyethylene bearing, and distal fixation with a 4-hole plate LC-LCP, with the goal of restoring the natural biomechanics of the hip.
Las deformidades estructurales del acetábulo como secuelas de displasia en el desarrollo de la cadera es una de las patologías más frecuentes que ameritan como tratamiento la cirugía de artroplastía total de cadera (ATC) asociada o no a osteotomía femoral en casos de luxación inveterada clasificada como Crowe 4. Múltiples técnicas han sido descritas, estudiadas y comparadas; sin embargo, no existe superioridad de una sobre otra. Actualmente, la osteotomía realizada por la mayoría de los cirujanos de cadera es subtrocantérica, se han reportado buenos resultados a 10 años de seguimiento. La necesidad de presentar una alternativa terapéutica con posibles beneficios, principalmente en la restitución del centro de rotación de la cadera, preservación de componente óseo proximal y disminución de las complicaciones, es meritoria en el campo quirúrgico. Por lo tanto, este estudio se propone describir la técnica quirúrgica de ATC asociada a osteotomía de acortamiento supracondílea en un paciente femenino de 29 años, con uso de copa acetabular no cementada, vástago corto no cementado con par de fricción cerámica-polietileno y fijación distal con placa LC-LCP de cuatro orificios, con el objetivo de restaurar la biomecánica natural de la cadera.

Currently, a new non-subtractive drilling technique, called osseodensification (OD), has been developed. It involves using specially designed drills with large negative cutting angles that rotate counterclockwise, causing expansion through plastic bone deformation, thus compacting the autologous bone to the osteotomy walls, which improves the primary stability of the implant.The present systematic review aimed to determine whether the OD technique can increase the primary stability of dental implants in the posterior maxilla region as compared to the conventional drilling (CD) technique.Five databases were searched up to June 30, 2022. The inclusion criteria embraced observational clinical studies, randomized and non-randomized controlled trials, human studies in vivo, comparing OD and CD, with the measurement of the primary stability of implants in the posterior maxilla region by means of the implant stability quotient (ISQ). The tools used to assess the risk of bias were RoB 2 and the NewcastleOttawa Scale (NOS).Seven articles met the inclusion criteria, with 4 classified as having a low risk of bias and 3 with a moderate risk of bias. The OD technique consistently demonstrated an average ISQ value of 73 KHz across all studies, whereas CD yielded an average value of 58.49 kHz (p < 0.001 for 5 articles).It can be concluded that in comparison with CD, OD improves primary stability at baseline in low-density bone, such as the maxilla.

Previous studies have compared the use of the Slocum- jig to the deformity reduction device (DRD) jig for the correction of distal femoral deformities of varying degrees in the frontal plane. The objective of the current study is to further investigate the use of the mini DRD jig in comparison to the Slocum jig for correction of varying degrees of torsional deformities of the distal femur. Femoral models (n = 60) were developed based on a CT scan of an approximately 16.5 kg normal canine femur. Models were created with a standard varus deformity of 15 degrees, and external torsional deformities of 15, 20, or 30 degrees. Using center of rotation of angulation (CORA) methodology, corrective osteotomies were planned and performed on each of the 3D printed models based on the group assigned. Modeling clay was applied the proximal femur to mimic visualization of a routine lateral surgical approach, while retaining the ability to palpate surgical landmarks. Post-correction anatomic lateral distal femoral angle (aLDFA) and femoral torsion angle (FTA) were measured and recorded. The mean post-correction FTA of groups using the DRD jig for correction were consistently closer to the ideal value compared to those using the Slocum jig, although these differences were not always statistically significant. Correction of external torsion between the DRD jig and the Slocum jig was significantly different in groups 1 and 2 (P = 0.026 and P = 0.046), but not in group 3. For the correction of varus deformity, no significant difference was found between the two jig types in any group. Results of this study suggest jig selection during distal femoral osteotomy for correction of torsional deformity may result in varying precision of post-correction alignment. Clinical significance of this variance remains unclear, and intra-operative visual assessment of alignment should be implemented to guide corrections.

BACKGROUND: Various fixation devices are available for bunion osteotomy. In this study, we evaluated the radiographic outcomes, postoperative complications, and recurrence rate in a series of hallux valgus deformities treated with various osteotomy procedures using a pin for the fixation of the osteotomy. METHODS: Two-hundred forty-seven patients with hallux valgus deformity managed with a Simple, Effective, Rapid and Inexpensive (SERI) osteotomy, distal chevron osteotomy, or proximal crescentic osteotomy and K-wire fixation were included. The mean follow-up of the patients was 53.9 ± 8.9 months. Radiographic evaluations included the assessment of the Hallux valgus angle (HVA), intermetatarsal angle (IMA), and union. Clinical evaluations included the assessment of the range of motion, pain in the first metatarsophalangeal joint, and patient satisfaction. RESULTS: In the last visit, the mean improvement of HVA was 23.9 ± 9.1º (P < 0.001). The mean IMA improvement was 6.1 ± 6º (P < 0.001). The mean metatarsophalangeal flexion and extension were 33 ± 10.7º and 34.6 ± 9.2º, respectively. Postoperative complications included pin tract infection in eight (3.2%) patients, deep infection in five (2%) patients, and early pin complication in four (1.6%) patients. Recurrence was observed in five (2%) patients. Twenty-three (9.3%) patients had slight pain in the last follow-up. The mean surgical time was smaller in the SERI osteotomy (P < 0.001). The mean hospitalization period was longer in the proximal osteotomy group (P = 0.039). The mean metatarsophalangeal flexion and extension were significantly smaller in the distal chevron osteotomy (P = 0.046 and P = 0.037, respectively). 90% of patients were satisfied or very satisfied with the surgical outcomes. CONCLUSION: K-wire fixation is a safe and effective device for the fixation of bunion osteotomy, and this effectiveness is even higher with SERI and proximal crescentic osteotomy.

OBJECTIVE: This study aimed to evaluate the safety and efficacy of skull-femoral traction followed by osteotomy correction in patients with severe spinal scoliosis and split cord malformation. METHODS: We retrospectively analyzed ten cases of severe spinal scoliosis with Pang I type split cord malformation treated between August 2012 and August 2023. Patients underwent skull-femoral traction prior to osteotomy correction. We assessed changes in height, weight, coronal and sagittal Cobb's angles, and physiological indicators such as vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in one second (FEV1), and blood gas levels before, during, and after treatment. RESULTS: Traction duration ranged from 9 to 19 days, with height and weight showing significant increases post-treatment. The coronal Cobb's angle improved from pre-treatment to post-corrective surgery and remained stable at the final follow-up. Similar improvements were observed in the sagittal plane. Physiological indicators such as VC, FVC, and FEV1, as well as blood gas levels, normalized after treatment. Nutritional status, indicated by triceps skinfold thickness, albumin, and transferrin concentrations, also improved. No neurological complications or device-related complications occurred during or after treatment. CONCLUSION: Skull-femoral traction followed by osteotomy correction is a safe and effective treatment for severe spinal scoliosis with split cord malformation, offering an alternative to high-risk procedures.

CASE: We report a 17-year-old boy with Klippel-Trénaunay syndrome (KTS) who underwent total hip arthroplasty with subtrochanteric shortening osteotomy through an extensile direct anterior approach (DAA) in the setting of Crowe IV hip dysplasia. The patient was transitioned from toe-touch weight-bearing to a progressive weight-bearing protocol at 6 weeks postoperatively and was ambulating painlessly at 3 months. CONCLUSION: Patients with KTS undergoing orthopaedic surgical intervention necessitate a multidisciplinary approach to care. This case demonstrates that THA in Crowe IV hip dysplasia with an associated subtrochanteric shortening osteotomy can be safely and successfully performed through an extensile DAA in this population.

BACKGROUND: the clubfoot is one of the most common pathologies in pediatric orthopedics. There are few studies of physical self-concept and perception of health in these patients. MATERIAL AND METHODS: observational, descriptive, and cross-sectional study. Population aged 16 to 18 years with the diagnosis of clubfoot. Being a sample of 55 patients, who underwent the SF-36, Laaveg-Ponseti Health Questionnaire, and the Physical Self-Concept Questionnaire. Evaluating physical abilities, physical condition, physical attractiveness. Presence of pain, general health, total function, emotional role, mental health, and satisfaction after treatment.There were 3 groups, according to the treatment received. Group 1, made up of 16 patients, treated only with the Ponseti method. Group 2 with 13 patients who received treatment with the Ponseti method, postero-medial release and osteotomies in the midfoot and/or hindfoot. And group 3 with 26 patients, who received postero-medial release and midfoot and/or hindfoot osteotomies. RESULTS: for the Laaveg-Ponseti questionnaire, comparing the score between the three groups, a statistically significant difference was found in group 1, with a higher score. In the Physical Self-Concept questionnaire and the SF-36 health questionnaire, no significant difference was found between the groups. CONCLUSION: the quality of life of patients with clubfoot are from excellent to good, no matter of the group to which they belonged. The state of physical and mental health by the SF-36 scale were fined. And physical self-concept evaluated was higher than the average. With these studies, we can expose a more comprehensive management. We find that the satisfaction of these patients will be fine in the future.

BACKGROUND: Severe kyphosis is a common condition in patients with advanced ankylosing spondylitis (AS). Although two-level osteotomy may serve as a potential alternative, it is often associated with increased blood loss and elevated surgical risks. To date, the optimal treatment for the challenging condition remains unclear. This study aims to introduce an effective strategy for the treatment of severe kyphosis secondary to AS, using one-level modified osteotomy combined with shoulders lifting correction method. METHODS: Seventy AS kyphosis who were treated with the strategy from 2012 to 2022, were reviewed retrospectively. All patients were followed up for a minimum duration of 2 years. Spinal and pelvic parameters were measured, including pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), lumber lordosis (LL), PI and LL mismatch (PI-LL), thoracic kyphosis, global kyphosis (GK), T1 pelvic angle (TPA), sagittal vertical axis (SVA), osteotomized vertebral angle (OVA), and chin-brow vertical angle (CBVA). Parameters of local osteotomized complex were measured and calculated, including the height of osteotomized complex and the length of spinal cord shortening. Clinical outcome was evaluated using Scoliosis Research Society-22 and Oswestry Disability Index scores. RESULTS: Seventy patients with average age of 39.8 years were followed-up for 29.3 months. Average operation time was 373.5 min, and average blood loss was 751.0 ml. Postoperatively, sagittal balance was successfully restored. GK decreased from 90.6° to 35.6°, LL decreased from 8.0° to -35.1°, TPA decreased from 56.8° to 27.8°, and SVA decreased from 24.4 cm to 8.7 cm (P < 0.05). A harmonious and matched spinopelvic alignment was achieved. PT decreased from 37.2° to 26.3°, PI-LL decreased from 54.1° to 10.2°, and SS increased from 9.2° to 19.7°(P < 0.05). Horizontal vision was obtained with postoperative CBVA of 8.8°. Average OVA correction was up to 47.3°, and the spinal cord was shortened by 24.3 mm, with a shortening rate of 36.0%. All patients demonstrated a favorable clinical outcome. No permanent nerve damage, screw loosening, rod breakage and main vascular injury were observed. One case required revision surgery due to screw cap loosening and delayed union. Solid bone fusion was achieved in all other patients. CONCLUSIONS: One-level modified osteotomy combined with shoulders lifting correction method is a safe and effective strategy for the treatment of severe AS kyphosis. This strategy offers a promising alternative for managing severe AS kyphosis, and may be particularly well-suited for individuals with concurrent osteoporosis. LEVEL OF EVIDENCE: Level IV, therapeutic study.

BACKGROUND: This systematic review and meta-analysis aimed to investigate the differences in hallux valgus angle (HVA), intermetatarsal angle (IMA), American Orthopedic Foot and Ankle Society (AOFAS) scores, and complication rates between chevron osteotomy and scarf osteotomy for correcting hallux valgus. METHODS: Two investigators independently searched for randomized controlled trials (RCTs) published from 2007 to 2018 on PubMed, Web of Science, and Cochrane Library databases. Next, chevron and scarf osteotomies were compared for their postoperative outcomes using HVA, IMA, and AOFAS scores and their complication rates. Meta-analysis was performed using Review Manager (version 5.3). RESULTS: Six RCTs-comprising 507 feet, of which 261 and 246 underwent chevron and scarf osteotomies, respectively-were included. The meta-analysis revealed that chevron osteotomy led to significantly smaller postoperative HVAs than scarf osteotomy (weighted mean difference [WMD] = -1.94, 95% CI = - 2.65 to - 1.29, P < .00001). However, the differences in postoperative IMA (WMD = - 0.44, 95% CI = - 1.10 to 0.22, P = .19), postoperative AOFAS scores (WMD = 0.75; 95% CI = - 5.32 to 6.82; P = .81), and complication rates (risk ratio = 1.22, 95% CI = 0.65-2.27, P = .53) between feet that underwent chevron and scarf osteotomies were nonsignificant. CONCLUSIONS: Compared with scarf osteotomy, chevron osteotomy had significantly more favorable postoperative outcomes in terms of HVA correction, but not in terms of IMA, AOFAS scores, or complication rates. LEVEL OF EVIDENCE: Level I, systemic review and meta-analysis.

BACKGROUND: An isolated medial patellofemoral ligament (MPFL) reconstruction (MPFLR) has been demonstrated to be an effective treatment option in the prevention of patellar instability, but there is growing support for performing a tibial tubercle osteotomy (TTO) in patients with an elevated tibial tubercle-trochlear groove distance. The purpose of this study was to evaluate the impact of adding a TTO to MPFLR on patient reported outcomes. METHODS: A retrospective review of patients who underwent MPFLR with or without TTO with a minimum of 12-month follow-up was performed. Patients in both groups were matched based on age, sex, and follow-up time. Recurrent instability (including re-dislocation and subluxation), visual analog scale (VAS) for pain score, Kujala score, and satisfaction were evaluated. RESULTS: There were 59 patients who underwent MPFLR with concomitant TTO performed at our institution and met our inclusion and exclusion criteria. These patients were then matched to patients undergoing isolated MPFLR based on demographics and follow-up time. The mean age was 25.0, 76.3% were female, and the mean follow-up time was 49 months. There was a significant difference in mean tibial tubercle-trochlear groove distance (19.8 ± 3.9 vs. 14.1 ± 2.8) between groups. There was no significant difference in VAS (1.48 ± 2.0 vs. 1.49 ± 2.1, p = 0.972), satisfaction (86.1% ± 24.2% vs. 81.2% ± 27.9, p = 0.311), or revision surgeries (10.2% vs. 10.2%) between groups. CONCLUSION: There was a low complication rate, excellent patient reported outcomes, and a low rate of recurrent patellar instability following TTO and MPFLR with allograft.

BACKGROUND: The periacetabular osteotomy (PAO) was developed to treat acetabular dysplasia and avoid the progression of osteoarthritis. Prior research has correlated demographic and radiographic variables with postoperative patient outcomes but with limited focus on patient expectations and correlation with satisfaction. The purpose of this study was to determine whether any such associations exist with the PAO. METHODS: An anonymous, de-identified satisfaction survey was applied to patients undergoing a PAO between April 2017 and April 2019. Forty patients (26 females) who underwent PAOs were included in the final analysis. The average age of the cohort was 22.0 ± 5.1 years of age. All patients had a minimum of 12 months of follow-up from the date of surgery. Patient demographics, diagnosis, and complications were recorded. Radiographs were then analyzed to determine pre- and postoperative lateral center edge angle (LCEA) and Tönnis roof angle, and correlations between satisfaction and radiographic analyses were performed. Statistical analysis included non-parametric Spearman's correlation and receiver operator characteristic. Statistical significance was set at p < 0.05. RESULTS: Thirty (75%) patients were satisfied with their outcome. There were no statistically significant associations between patient age or sex and postoperative satisfaction (p > 0.05). The average LCEA was 10.9° ± 6.9° preoperatively and 26.0° ± 4.2° postoperatively with an average change of 15.1° ± 5.6°. The average Tönnis angle was 18.8° ± 3.3° preoperatively, decreasing to 11.6° ± 3.2° postoperatively with an average change of -7.2° ± 3.2°. Interobserver reliability was high, ranging from r = 0.782, p < 0.001 for postoperative Tönnis angle to r = 0.958, p < 0.001 for preoperative LCEA. Preoperative LCEA correlated positively with satisfaction, r = 0.351, p = 0.027. Logistic regression demonstrated that for every increasing degree of preoperative LCEA, odds of postoperative satisfaction increased by 1.13 (95% CI: 1.01 to 1.27), p = 0.034. CONCLUSION: This study suggests that postoperative patient satisfaction after PAO may be associated with preoperative patient demographics such as LCEA. It also suggests that more dysplastic hips may have lower rates of postoperative satisfaction than patients with less severe deformity. These associations warrant further study, which may yield prognostic value for future surgery.

BACKGROUND: Surgical treatment of insertional Achilles tendinopathy (IAT) historically consists of Achilles tendon debridement with reattachment and excision of the posterosuperior calcaneal prominence with or without a gastrocnemius recession. Zadek osteotomy (ZO) is an alternative to an open midline splitting approach. The purpose of this study was to analyze patient-reported outcomes and complications after percutaneously performed ZO with minimum 2 years' follow-up. METHODS: One hundred eight cases treated with percutaneous ZO with a minimum 2-year follow-up were retrospectively reviewed. Postoperative complications and patient satisfaction were evaluated. Foot Function Index (FFI) and visual analog scale (VAS) scores were recorded at preoperative and follow-up appointments to measure patients' functional outcomes and pain, respectively. RESULTS: Mean follow-up was 41.2 months (range, 24-65). Mean age was 51.8 years (range, 28-81). The mean FFI score improved from 56.1 (range, 47-88) to 11.0 (range, 7-59) postoperatively (P < .001). The mean VAS score improved from 7.7 (range, 5-10) to 0.4 (range, 0-7) postoperatively (P < .001). The overall complication rate was 3.8% (n = 4). Of 104 cases, 98.1% of patients said they were satisfied with their procedure (n = 102) when asked if they were satisfied with their ZO and recovery. CONCLUSION: We found the percutaneous ZO to be a safe and effective intervention for treatment of IAT. At a minimum of 2-year follow-up, this intervention is associated with minimal complications, improved function, reduced pain, and a high rate of patient satisfaction.

BACKGROUND AND PURPOSE: Hip dysplasia can present challenges for total hip arthroplasty (THA) due to anatomic abnormalities. We aimed to assess the association of age, sex, osteotomies prior to THA, and fixation method on 5- and 10-year revision-free implant survival and patient-reported outcome measures (PROMs) of THAs in patients with hip dysplasia. METHODS: Using Dutch Arthroplasty Register data, we studied hip dysplasia patients receiving primary THAs in 2007-2021 (n = 7,465). THAs were categorized by age, pelvic osteotomy prior to THA (yes/no), and fixation (cemented, uncemented, hybrid, reverse hybrid). Kaplan-Meier and multivariable Cox models were used to determine 5- and 10-year revision-free implant survival and adjusted hazard ratios including 95% confidence intervals (CIs). Reasons for revision and PROMs were compared within the categories. RESULTS: We found a 10-year revision-free implant survival of 94.9% (CI 94.3-95.5). Patients younger than 50 years had a 10-year implant survival of 93.3% (CI 91.9-94.7), Patients with prior pelvic osteotomy had a 10-year implant survival of 92.0% (CI 89.8-94.2). Fixation method and sex were not associated with implant survival. Patients with a prior pelvic osteotomy had more revisions due to cup loosening and reported lower PROM scores than patients without earlier osteotomy. CONCLUSION: 5- and 10-year revision-free implant survival rates of THA for hip dysplasia are 96.4% and 94.9%. Age and prior osteotomies were associated with decreased implant survival rates in patients with hip dysplasia, while fixation method was not. Prior osteotomies were also associated with reduced PROM scores.

AIMS: Primary malignant bone tumor of the pelvis is an uncommon lesion, the resection of which via freehand osteotomy is subject to inaccuracy due to its three-dimensional anatomy. Patient-Specific Guides (PSG), also called Patient-Specific Instruments (PSI) are essential to ensure surgical planning and resection adequacy. Our aim was to assess their use and effectiveness. METHODS: A monocentric retrospective study was conducted on 42 adult patients who underwent PSG-based resection of a primary malignant bone tumor of the pelvis. The primary outcome was the proportion of R0 bone margins. The secondary outcomes were the proportion of overall R0 margins, considering soft-tissue resection, the cumulative incidence of local recurrence, and the time of production for the guides. A comparison to a previous series at our institution was performed regarding histological margins. RESULTS: Using PSGs, 100% R0 safe bone margin was achieved, and 88% overall R0 margin due to soft-tissue resection being contaminated, while the comparison to the previous series showed only 80% of R0 safe bone margin. The cumulative incidences of local recurrence were 10% (95% CI: 4-20%) at one year, 15% (95% CI: 6-27%) at two years, and 19% (95% CI: 8-33%) at five years. The median overall duration of the fabrication process of the guide was 35 days (Q1-Q3: 26-47) from the first contact to the surgery date. CONCLUSIONS: Patient-Specific Guides can provide a reproducible safe bony margin.

The aim of this study was to develop a novel surgical technique for stifle arthrodesis in dogs using a semicircular saw for tibial and femoral ostectomies through a medial approach. Ten pelvic limbs from five canine cadavers underwent stifle arthrodesis. Prior to the surgical procedure, the limbs were radiographed to rule out musculoskeletal abnormalities. Additionally, the radiographs were used for surgical planning. For the tibial ostectomy, the center of the intercondylar eminences, the cranial limit of the tibial plateau, and the caudal cortex of the tibia were used as landmarks. In the femur, the groove of the insertion of the long digital extensor tendon and the caudal portion of the femoral cortex served as references. The most significant iatrogenic injury during the surgical procedures was the complete rupture of the long digital extensor tendon during the tibial cut in one of the stifles. Dome ostectomies facilitated interfragmentary contact, allowing for adjustment of the angulation between the fragments without the need for additional ostectomies or osteotomies. The medial approach provided a clear view of intra-articular structures without causing extensive damage to surrounding tissues. After the procedures, the limbs were radiographed to calculate angular measurements, and the final angulation (mean) of the knee joints was 134.7 ± 11°.
