Solitary medial proximal tibial osteochondromas cause pes anserinus syndrome in adolescents.

Objective: Osteochondromas are common bone tumors with hyaline cartilage-covered heads, arising from cortical and medullary bone. Solitary medial proximal tibial osteochondromas (MPTOs) can cause pes anserinus syndrome via compression. However, the literature lacks comprehensive studies on MPTO-related pes anserinus syndrome and its surgical outcomes. Material and Method: The study reviewed 227 patients diagnosed with osteochondroma between January 2018 and January 2022, with 21 patients meeting inclusion criteria: under 19 years, MPTO, surgical excision, histological diagnosis, ≥1-year follow-up. Cases with irregular follow-ups and multiple hereditary exostoses were excluded. Different surgical techniques were employed based on lesion characteristics. Postoperative weight bearing was allowed, and follow-ups involved postoperative complications assessment, clinical data collection, imaging, and functional evaluations using the International Knee Documentation Committee (IKDC) and Hospital for Special Surgery Pediatric Functional Activity Brief Scale scoring systems. Results: The study involved 21 adolescents (15 ± 2 years). Lesion types were predominantly pedunculated (86%) and surgical interventions involved pes anserinus split (76%) or tenoplasty (24%). No significant correlations were observed between lesion dimensions and IKDC scores. Split intervention led to a significant improvement in IKDC scores (p < 0.01), while tenoplasty showed similar results (p < 0.05). Athlete status did not affect IKDC scores significantly, but both athletes and non-athletes demonstrated improvements (p < 0.05). Conclusion: The negative impact of MPTOs causing pes anserinus tendinitis on the patient's quality of life and activity can be completely corrected with surgical treatment. Complete pes anserinus tendon cutting and subsequent repair are recommended if they facilitate surgery. The study underscores the importance of surgical management for MPTO-related pes anserinus syndrome and provides insights into the effectiveness of different surgical techniques.

Spinal Melorheostosis: A Rare Presentation.

CASE: A 22-year-old female patient was referred to the orthopaedic department for further examination after a radiopaque area was observed in the T6 vertebra in her chest radiograph. Computed Tomography (CT) showed a sclerotic mass with smooth borders, involving the entire body of the T6 vertebra, left posterior elements, posterior of the rib past the left zygapophyseal joint, and a "flowing candle wax" image toward the T7 vertebra. Spinal melorheostosis was considered radiologically in the patient, but malignancy could not be completely excluded. Thereupon, open biopsy was performed under general anesthesia. CONCLUSION: Spinal melorheostosis is a rare condition. Histological examination should be considered in cases where the diagnosis remains suspicious after clinical and radiological evaluations.

Floating phalanx; simultaneous double dislocation of the interphalangeal joint in a finger: A case report and literature review.

Isolated proximal and distal interphalangeal joint (DIPJ) dislocations are widely seen as a result of sporting injuries and major trauma. The combination of dorsal dislocation of the DIPJ in the same finger concomitant to traumatic dorsal dislocation of the proximal interphalangeal joint (PIPJ) is a rarely seen injury. The case is, here, presented of a 65-year-old female patient with proximal and DIPJ dislocation of the right-hand ring finger accompanied by volar and dorsal plate injuries in the proximal and distal joints. With this case, it was aimed to introduce a new term of 'floating phalanx' into medical literature. The treatment was applied to the patient of closed reduction under peripheral block and the application of an aluminium finger splint in semiflexion. In a 24-month follow-up period, the 4th finger of the patient was observed to be stable and has pain-free range of movement. This case is an uncommon case of volar and dorsal plate avulsion fractures with PIPJ and DIPJ dorsal dislocation treated successfully with closed reduction and conservative treat-ment with excellent functional results.

Implant survival and functional results of endoprosthetic reconstruction for proximal femoral metastases with pathological fractures.

BACKGROUND: This study aimed to evaluate the patient and implant survival, clinical and functional outcomes, and the rate of complications resulting in reconstruction failure following endoprosthetic reconstruction (EPR) of extensive proximal femoral metastases associated with actual or impending pathological fractures. METHODS: A total of 111 patients with actual or impending pathological fractures due to metastatic disease of the proximal femur were treated with EPR between 2003 and 2018. Staged surgery, bilateral EPR, was performed in 3 cases. The patients comprised 51 females and 60 males with a mean age of 52.1 ± 12.3 years. The patient and implant survival were recorded. Clinical and functional outcomes were assessed by using the visual analogue scale (VAS), Musculoskeletal Tumour Society (MSTS) functional scoring, and Karnofsky Performance Scale (KPS). The different types of abductor mechanism repair were evaluated by functional tests and existence of Trendelenburg gait at postoperative follow-ups. The complications resulting in reconstruction failure were investigated. RESULTS: The mean follow-up was 23.1 ± 17.9 months. The overall survival of patients after EPR was 89% at 6 months, 72% at 1 year and 10% at 5 years. The estimated 1- and 5-year overall implant survival was 100% and 97.3% (95% CI, 0.95-0.98), respectively, as the endpoint was defined as complete removal of the prosthesis. Median VAS score before endoprosthetic replacement was 8 and after 3 months 4. Before surgery, the median MSTS score was 40 (30-56.6%) and the median KPS score was 40 (30-50). Postoperative third month, the median MSTS score was 56.6 (53.3-86.6%) and the median KPS score was 60 (40-70). Functional scores were superior in trochanter major split osteotomized group compared to trochanter major removed group. Trendelenburg gait was seen in 20 (17.5%) patients postoperatively. There were 10 (8.7%) complications resulting in reconstruction failure. CONCLUSION: Endoprosthetic replacement can provide a durable fixation with high implant survival rate and good clinical and functional results in extensive proximal femoral metastases associated with a pathological fracture.

Prediction of soft tissue coverage following distal femur bone sarcoma resection: A preliminary report.

We aimed to examine the predictability of the need for soft tissue reconstruction during limb-sparing surgery through preoperative magnetic resonance (MR) imaging in patients diagnosed with a malignant bone tumor in the distal femur. The study included 42 patients who were operated for a bone sarcoma of the distal femur at our clinic between 2016 and 2018. The recorded parameters included the demographic characteristics of the patients, tumor diagnosis, tumor side, total tumor volume, tumor soft tissue component volume, tumor soft tissue component volume-to-total tumor volume ratio, tumor localization by MR imaging, the need for soft tissue reconstruction, the muscles used for soft tissue reconstruction, the biopsy site, and the biopsy type. Tumor volume was calculated on MR imaging of the distal femur region performed before surgery. Our study established cut-off values for soft tissue reconstruction need following resection as a total tumor volume of 96.4 cm3 , a tumor soft tissue component volume of 22 cm3 , a tumor soft tissue component volume-to-total tumor volume ratio of 48.9%, and tumor localization in two different regions on axial distal femoral MR images. Considering these cut-off values, by calculating tumor volume values preoperatively we can predict the need for rotational muscle flaps for soft tissue coverage following distal femur bone sarcoma resection and endoprosthesis reconstruction. Anticipating the need for soft tissue reconstruction may affect the duration and success of the operation.

Is bipolar hemiarthroplasty an appropriate type of hip articulation following proximal femoral or total femoral resections for musculoskeletal malignancies?

BACKGROUND: Different approaches are applied for reconstruction in patients with a musculoskeletal malignancy which require a proximal femoral or total femoral resection. We aimed to evaluate the treatment outcomes of patients who underwent a proximal femoral or total femoral resection due to bone and soft tissue tumors and had an endoprosthetic reconstruction by a bipolar hemiarthroplasty type of hip articulation. METHODS: We retrospectively identified 133 patients who underwent a proximal femoral or total femoral endoprosthetic replacement after resection of a bone or soft tissue malignancy. There were 74 male and 59 female patients, with a mean age of 55.02 ± 16.92 years (range 11-84 years) and a median follow-up of 24.47 ± 24.45 months (range 6-164 months). Patient demographics, surgical, and oncological data were recorded. Acetabular wear was measured using the classification proposed by Baker. Functional assessment was performed using the Musculoskeletal Tumor Society (MSTS) functional score. RESULTS: There was no statistically significant difference among primary diagnostic groups in terms of gender, prosthesis type, trochanter major resection, local recurrence, complication/revision rate, and MSTS Score (p > 0.05, for each parameter). On the other hand, a statistically significant difference was detected in terms of degree of acetabular erosion among diagnostic groups (p < 0.001); the acetabular erosion rate (AER) was found to be lower in patients with metastatic carcinoma than in patients with a diagnosis of primary bone or soft tissue sarcoma. The univariable analysis revealed that the effect of age, primary diagnosis, localization, follow-up time, and presence and number of distant organ metastasis variables on AER were found to be statistically significant (p = 0.018, p = 0.035, p = 0.002, p = 0.007, p = 0.031, p = 0.040, respectively). CONCLUSION: In patients who undergo a proximal femoral or a total femoral resection due to a musculoskeletal tumor, bipolar hemiarthroplasty is an adequate type of hip articulation method, since it does not affect the revision requirements and functional outcomes of patients with acetabular erosion.

Is physical examination as effective as magnetic resonance imaging in the diagnosis of suspected pediatric scaphoid fractures?

OBJECTIVE: The aim of this study was to evaluate whether careful physical examination is as effective in diagnosis as magnetic resonance imaging (MRI) in pediatric patients with suspected scaphoid fractures and whether radiography is sufficient in the follow-up of these patients. METHODS: This prospective study included patients with tenderness of the anatomic snuffbox on physical examination and no fracture on radiography between 2015 and 2019, and the data were evaluated retrospectively. A short-arm thumb spica casting was applied for an initial diagnosis of suspected scaphoid fracture. MRI was performed within 1 week after initial trauma. Physical examination and X-rays at 2-week intervals were applied during the follow-up period. The functional outcomes were evaluated using the Modified Mayo Wrist score. RESULTS: A total of 92 patients (28 girls and 64 boys; mean age: 12.32±2.22 years) were diagnosed with suspected scaphoid fracture on physical examination and MRI was performed. The MRI confirmed the suspected scaphoid fracture at the rate of 77.2% (n=71). The sensitivity obtained for the radiograph was 14.08%, specificity was 100%, positive predictive value was 100%, and negative predictive value was 25.61%. The mean Modified Mayo Wrist score was 92.43±2.64 (range, 85-98). CONCLUSION: Detection of tenderness on the anatomic snuffbox without determination of fracture radiographically should be evaluated and treated in favor of a scaphoid fracture. These fractures are mostly treated successfully with conservative treatment.

The impact of pathological fractures on surgery, morbidity, functional and oncological outcomes in patients with primary bone sarcomas.

Background Although rare, pathological fractures may occur in primary bone sarcomas. There have been studies reporting that such patients have a poorer prognosis than those without a pathological fracture. This study investigates the impact of pathological fractures on surgery, morbidity, functional and oncological outcomes in patients with primary bone sarcomas. Patients and methods A retrospective analysis of 568 patients with primary bone sarcomas, treated between 2005 and 2019, was performed. The study included 41 patients with a pathological fracture and 51 control patients who did not have a pathological fracture. A multivariate Cox regression analysis was used to investigate the impact of pathological fractures and further independent variables on amount of intraoperative bleeding, duration of surgery, number of muscles and major neurovascular structures included in resection, tumor volume, surgical volume, Musculoskeletal Tumor Society (MSTS) functional score, postoperative complication rate, and local recurrence, distant metastasis, and survival rates. Results There were 36 (39%) female and 56 (61%) male patients. No statistically significant difference was noted in tumor volume, tumor/surgical volume percentage, number of major neurovascular structures included in resection, postoperative complication rate, and local recurrence, distant metastasis, and survival rates between the two groups (p > 0.05). A significantly higher amount of intraoperative bleeding and number of transfused blood components, a longer duration of surgery, and a higher amount surgical volume and number of resected muscles were detected in Group 1 compared to Group 2 (p=0.001, p=0.002, p=0.007, p=0.007, p < 0.001, respectively). The MSTS functional scores were lower in patients with a pathological fracture than in those without a pathological fracture (p=0.001). Conclusion We conclude that a pathological fracture through a primary bone sarcoma has no adverse effect on prognostic factors such as local recurrence, distant metastasis, and survival. However, pathological fractures increase the amount of intraoperative bleeding and surgical volume and result in a longer surgery, in addition to decreased functional outcomes.

Indications of amputation after limb-salvage surgery of patients with extremity-located bone and soft-tissue sarcomas: A retrospective clinical study.

OBJECTIVE: This study aimed to investigate amputation-related factors after limb-salvage surgery (LSS) in patients with extremity-located bone and soft-tissue sarcomas and determine the relationship between these factors and patient survival. METHODS: In this retrospective study at our institution, patients in whom LSS was first performed because of an extremity-located musculoskeletal sarcoma, and subsequently amputation was carried out for various indications were included. Patient and tumor characteristics, details of surgical procedures, indications of amputation, number of operations, presence of metastasis before amputation, and post-amputation patient survival rates were analyzed. RESULTS: A total of 25 patients (10 men, 15 women; mean age=41.96±21.88 years), in whom amputation was performed after LSS as initial resection of an extremity sarcoma or re-resection(s) of a local recurrence, were included in the study. The leading oncological indication for amputation was local recurrence that occurred in 18 (72%) patients. Non-oncological indications included prosthetic infection in 5 (20%), mechanical failure in 1 (4%), and skin necrosis in 1 (4%) patient. The patients underwent a median of 2 (range, 1-4) limb-salvage procedures before amputation. Distant organ metastasis was detected in 22 (88%) patients during follow-up; in 13 (52%) of these patients, metastasis was present before amputation. A total of 11 (44%) patients were alive at the time of study with no evidence of the disease (n=3) or with disease (n=8), and 14 (56%) patients died of disease. The mean overall and post-amputation survival were 47±20.519 (range, 11-204) months and 22±4.303 (range, 2-78) months, respectively. The median follow-up was 27 (range, 6-125) months. CONCLUSION: The most common causes of amputation after LSS were local recurrence and prosthetic infection. Patients who underwent amputation after LSS developed a high rate of distant organ metastasis during follow-up and had reduced survival. LEVEL OF EVIDENCE: Level IV, Therapeutic Study.

Pelvic Ring Reconstruction After Iliac or Iliosacral Resection of Pediatric Pelvic Ewing Sarcoma: Use of a Double-Barreled Free Vascularized Fibular Graft and Minimal Spinal Instrumentation.

BACKGROUND: In patients undergoing iliosacral resections, pelvic ring reconstruction can maintain stability of the pelvis and spinal column, which is expected to achieve good functional outcomes. However, no optimal reconstruction method has been established. We aimed to analyze the outcome of pelvic ring reconstruction using double-barreled free vascularized fibular graft (FVFG) and internal fixation after iliosacral resections in children. METHODS: We retrospectively reviewed 16 children with pelvic Ewing sarcoma who underwent pelvic ring reconstruction using double-barreled FVFG after iliosacral resection. The fibular graft was placed between the supraacetabular region distally and the remaining ilium or sacrum proximally. The stability of the remaining pelvis and spinal column was provided by minimal spinal instrumentation. RESULTS: Eleven Type-I and 5 Type-I+IV resections were performed for 10 boys and 6 girls, who had a mean age of 13.4 years (range, 10 to 18 years). The mean follow-up was 49.8 months (range, 28 to 96 months). At the time of the final follow-up, 14 patients were alive and 2 patients had died of disease. The mean time for bone union was 9 months (range, 6 to 12 months). Graft hypertrophy was evident in all patients at 12 months. The median Musculoskeletal Tumor Society (MSTS) score at the time of the final follow-up was 80% (range, 60% to 96.6%). Seven patients had complications. Three complications required reoperation: 1 deep infection, 1 hematoma, and 1 wound dehiscence. Three patients had disease relapse in terms of lung metastases. CONCLUSIONS: This reconstruction method can achieve a high rate of bone union and can provide good functional outcomes following resection of pediatric pelvic Ewing sarcomas with iliosacral involvement. Complications are usually manageable without a need for revision surgical procedures. LEVEL OF EVIDENCE: Therapeutic Level IV.

Are Cemented Endoprosthetic Reconstructions Superior to Uncemented Endoprostheses in Terms of Postoperative Outcomes and Complications in Patients with Extremity-Located Bone Metastasis Scheduled for Adjuvant Radiotherapy?

BACKGROUND: Adjuvant radiotherapy frequently is used for prevention of recurrence following resection and endoprosthetic reconstruction of bone metastases. Besides this positive effect, radiotherapy can negatively affect both cemented and uncemented endoprostheses. METHODS: We retrospectively analyzed 130 extremities of 115 patients who underwent resection and cemented or uncemented endoprosthetic reconstruction for bone metastasis, followed by postoperative radiation therapy. The functional improvement was assessed by Karnofsky Performance Scale and Musculoskeletal Tumor Society (MSTS) scoring. The radiological evaluation mainly included analysis of "loosening areas" which were defined as the regions of osteolysis between the stem of the endoprostheses and the cement or cortex. The complications resulting in reconstruction failure and patient survival were recorded. RESULTS: A survival analysis revealed that 21 (18.3%) patients were alive with disease and 94 (81.7%) died of disease at the time of study. The mean last follow-up Karnofsky Performance Scale and MSTS scores of the whole study cohort were 78.69 ± 8.66 and 82.15 ± 9.06, respectively. There were 8 (6.15%) complications resulting in reconstruction failure, including aseptic loosening (2), femoral stem breakage (2), periprosthetic fracture (2), and infection (2). The number and time of complications did not show a significant difference between the cemented and uncemented groups (P > .05). CONCLUSION: This study demonstrated that there was no significant difference in complication rates of cemented or uncemented endoprosthetic reconstructions in patients with extremity-located bone metastases scheduled for adjuvant radiotherapy. The only result in favor of cemented prostheses was significantly higher MSTS functional scores at last follow-up.

Reconstruction after periacetabular tumor resection with Lumic® endoprosthesis: What are the midterm results?

INTRODUCTION: This study aimed to analyze the midterm outcomes of LUMiC® endoprosthetic reconstruction following periacetabular resection of primary bone sarcomas and carcinoma metastases. PATIENTS AND METHODS: We retrospectively reviewed the charts of 21 patients (11 male [52.3%], 10 female [47.6%]; mean age 47 ± 16 years) for whom a LUMiC® endoprosthesis (Implantcast) was used to reconstruct a periacetabular defect after internal hemipelvectomy. The tumor was pathologically diagnosed as Ewing's sarcoma in six (28.5%), chondrosarcoma in 10 (47.6%), and bone metastasis from carcinoma in five (23.8%) patients. RESULTS: The median follow-up of patients was 57.8 months (95% confidence interval: 51.9-63.7). The implant survival rate at 1, 2, and 5 years were 95.2%, 85.7%, and 80.9%, respectively. The overall complication rate was 33.3% (n = 7). Four (19%) complications resulted in reconstruction failure. Total reoperation rate was 28.5% (n = 6). The complications were soft tissue failure/dislocation in two patients, aseptic loosening in one, infection in two, and local recurrence in two. At the time of study, seven patients were alive with no evidence of disease, seven were alive with disease, and seven died of disease. The 5-year overall survival rate and local recurrence-free survival rates were 67% and 76%, respectively. The median Musculoskeletal Tumor Society score at final follow-up was 70% (range: 50%-86.6%). CONCLUSION: We conclude that LUMiC® endoprosthesis provides good functional outcomes and a durable reconstruct. Even though this reconstruction method presents some complications, it provides a stable pelvis in the management of periacetabular malignant tumors.

Factors affecting postmusculoskeletal tumour surgery wound problem treatment with negative pressure wound therapy.

The aim of the study is to investigate the risk factors identified in literature that have been associated with prolonged Negative Pressure Wound Therapy (NPWT). Our study included patients who developed local wound problems after bone or soft tissue sarcoma surgery with negative margin at our clinic between 2012 and 2018 and treated with NPWT. All patients were followed up of at least 6 months. Sex, albumin level, skin infiltration, type of wound problem, postoperative intensive care unit (ICU) requirement, and intraoperative blood loss were found to be influential factors on NPWT > 10 sessions. We conclude that treatment may be prolonged and the necessary precautions need to be taken in patients with an impaired preoperative nutritional condition, with intraoperative high amount of blood loss, and with long postoperative stays in the ICU as well as if the underlying cause for wound problem is an infection.

Locked Traumatic Pisiform Dislocation: A Case Report.

CASE: A 32-year-old man presented to the emergency department with several carpal bone fractures and a locked distal pisiform dislocation after trauma. Treatment consisted of open surgical and reduction, osteosynthesis with a single Kirschner wire, and ligament repair. The patient's functional outcome was excellent, and his Mayo wrist score was 90 at 36 months after injury. CONCLUSIONS: Pisiform dislocations may be difficult to diagnose because anteroposterior and lateral radiographs may not be sufficient to visualize the injury. A 30° semisupinated wrist x-ray and computed tomography can be helpful. A satisfactory clinical result may be achieved if distal pisiform dislocations are detected early and managed surgically with open reduction and ligament repair.

Surgical treatment of type III acromioclavicular dislocation: Bosworth technique versus hook plating.

OBJECTIVE: In this study, it was compared the clinical results of the Bosworth technique and hook plating in acromioclavicular (AC) dislocations. METHODS: 44 patients are retrospectively evaluated in this study whom diagnosed as type III AC dislocations and treated by two different surgical methods in two different clinics. The patients were 30 males and 14 females with a mean age of 44 years (range, 18-80 years). The patients were divided into 2 groups according to the applied surgical technique. Group I comprised 25 patients to whom coracoclavicular fixation was applied by using the Bosworth technique. Group II comprised 19 patients to whom acromioclavicular fixation was applied by using hook plate. All patients are evaulated by The University of California at Los Angeles Shoulder Score (UCLA) and The disabilities of the arm, shoulder and hand (DASH) scoring system. RESULTS: The mean follow-up period was 23 months (range, 12-42 months). A statistically significant diffference was determined between the surgical groups in respect of the modified UCLA scale (p=0.012) and Quick DASH score (p=0.008). Hook plating group had better clinical results according to Bosworth group in terms of both UCLA and DASH score. A statistically highly significant negative correlation was determined between the UCLA and DASH scores (r=0.677, p=0.000). CONCLUSION: Although hook plating had better clinic outcomes compared to Bosworth technique, there is not seen difference between two groups in terms of the time of return to work. Treatment of the AC dislocation should perform early reconstruction for better reduction, fewer complications and higher levels of patient satisfaction.

Surgical treatment of distal tibia fractures: open versus MIPO.

BACKGROUND: Treatment of the distal tibial fractures are challenging due to the limited soft tissue, subcutaneous location and poor vascularity. In this control-matched study, it was aimed to compare the traditional open reduction and internal fixation with minimal invasive plating (MIPO). We hypothesized that superior results may be achieved with MIPO technique. METHODS: 22 patients treated with traditional open reduction and internal fixation were matched with 22 patients treated with closed reduction and MIPO on the basis of age (±3), gender, and fracture pattern (AO classification). Evaluation was assed according to the wound problems, the American Orthopaedic Foot and Ankle surgery (AOFAS) scoring, radiological union, malunion, delayed union, hospitalisation time, time from injury to surgery, and operation time. RESULTS: There was no significant difference in the distribution of AO/OTA classification, age, gender, AOFAS score, time from injury to operation, follow-up, bone union time, delayed union, malunion and infection (p>0.05). The operation time was significantly longer in the open group than in the MIPO group: 69.59±7.21 min. for the ORIF, and 61.14±5.61 for the MIPO group (p<0.01).The hospitalisation time was significantly longer in the open group than in the MIPO group: 7.64±4.71 days for the MIPO, and 10.18±4.32 days for the ORIF group (p<0.05). CONCLUSION: MIPO technique can be beneficial for the treatment of distal tibia AO/OTA A and B type fractures with reduced hospital stay, cost-effectiveness, and infection rate.

Does the anteromedial portal provide clinical superiority compared to the transtibial portal in anterior cruciate ligament reconstruction in nonprofessional athletes in short-term follow-up?

OBJECTIVE: Two drilling techniques of the femoral tunnel are commonly used in anterior cruciate ligament (ACL) reconstruction: through the transtibial (TT) portal or through the anteromedial (AM) portal. The aim of the present study is to investigate the radiological and clinical outcomes of arthroscopic single-bundle ACL reconstruction using AM and TT portal techniques for drilling the femoral tunnel in nonprofessional athletes. METHODS: A retrospective review was made of 44 nonprofessional athletes undergoing ACL reconstruction using AM and TT techniques between 2011-2013. The femoral tunnel clock position on axial magnetic resonance imaging (MRI) and the anterior-posterior position of the tibial tunnel on sagittal-cut MRI scan were measured. Radiological femoral tunnel and tibial tunnel anterior-posterior inclination angles were assessed. At final follow-up, the Lachman test and pivot-shift test were used in the evaluation of the anterior-posterior stability of the knee and the rotational stability of the knee. For clinical and functional evaluation, the modified Cincinnati knee grading system, Lysholm knee scoring scale, and International Knee Documentation Committee (IKDC) form were used. RESULTS: No statistically significant difference was determined between the groups in terms of patient age, follow-up period, gender, and affected side distribution. There were 6 outliers in the TT group due to the clock face position. The mean femoral tunnel inclination angle was 31.07°±8.44° in the AM group and 19.02°±8.93° in the TT group. The tibial tunnel inclination angle was 21.08°±5.42° in the TT group and 16.58°±7.02° in the AM group. A statistically significant difference was determined between the 2 groups. No statistically significant difference was observed between the 2 groups in terms of Lachman test, pivot-shift test, Lysholm score, IKDC score, and modified Cincinnati score results. CONCLUSION: The AM technique has no clinical superiority compared to the TT technique in ACL reconstruction in nonprofessional athletes.

One-stage surgical treatment of neglected simultaneous bilateral locked posterior dislocation of shoulder: a case report and literature review.

Simultaneous bilateral locked posterior dislocation of the shoulder is a rare injury. Herein, we present a 59-year-old male case with a three-month history of an irreducible locked bilateral posterior dislocation of the shoulders with an associated large impression fracture on the anteromedial aspect of both humeral heads after a grand mal type epileptic seizure. Plain X-ray and computed tomograph revealed a defect on the right side more than 40% of the articular surface, and on the left side, 30%. He was treated with a one-stage operation with a reconstruction of femoral head osteochondral allograft on the right side and transfer of the osteotomized tuberculum minus with its attached subscapularis tendon into the defect (modified McLaughlin technique) on the left side. At 14 months during follow-up, the patient was pain-free with stable shoulder joints and satisfactory functionality.

Chronic wrist pain in a goalkeeper; bilateral scaphoid stress fracture: A case report.

INTRODUCTION: Bilateral scaphoid stress fractures are uncommon, and rarely presented with chronic wrist pain. Most fractures of the scaphoid heal with immobilization. Presentation of case The case presented here is of a bilateral stress fractures of the carpal scaphoid in a 19-year-old male.The patient had been playing as a goalkeeper and presented with a 4-year history of chronic pain in both wrists. We had a successful result in the treatment of these stress fractures with long- arm thumb plaster cast.Discussion Most fractures of the scaphoid in the immature skeleton heal with immobilization. Approximately 88-95% of acute scaphoid fractures are said to heal with conservative treatment using cast immobilisation. Non-surgical treatment is successful for scaphoid fractures in children and for those fractures which are non-displaced, stable, and where there is no damage to other bones or ligaments. In stable fractures, union is achieved within 8-12 weeks.Conclusion Bilateral stress fractures of the scaphoid can be considered for the wrist pain, especially for the patients that had repetitive minor wrist trauma, and in spite of developments in surgical techniques and materials used, treatment by plaster casting should still be considered initially for non-displaced, stable scaphoid stress fractures.

Using fibula as a reference can be beneficial for the tibial component alignment after total knee arthroplasty, a retrospective study.

PURPOSE: One of the important factors in a successful arthroplasty is component alignment. The primary objective of this study was to determine whether the fibular shaft reference technique is beneficial for the tibial component position on the postoperative plain radiograph after total knee arthroplasty. METHODS: A total of 42 patients between 2009 and 2011 were analysed retrospectively. The surgeon prepared the tibia using an extramedullary cutting guide and set the posterior tibial slope with respect to the fibular reference rod. In the postoperative radiographic measurements, a true anteroposterior and lateral radiograph of the lower leg covering the whole length of the tibia was used. RESULTS: Five patients were excluded as they did not meet the inclusion criteria, four patients were excluded due to improper radiographs and the study group was reduced to 33 patients and 35 knees. The mean preoperative tibiofibular angle was 2.1° ± 0.8°. The mean postoperative tibial sagittal angle measurements were 83.3° ± 1.4° (81°-86°). 33 (94 %) Knees gained the desired tibial sagittal angle within the desired alignment (5° ± 3°). The mean postoperative tibial coronal angle was 89.3° ± 1.5°. The tibial component coronal angle of two knees was more than 3 alignment from the neutral mechanical axis. CONCLUSION: The major clinical relevance of the technique described in the present study is cost-effectiveness, and it does not require any extra time or surgical equipment. This method can be used as an alternative choice for bulky extremities which is a cause of malalignment of the components. LEVEL OF EVIDENCE: Retrospective case series, Level IV.
