Methods: The SACSwas translated into Turkish according to Beaton's recommendations.

Reliability of RUST and modified RUST scores for evaluation of union in pediatric and adult femoral shaft fractures.

Objective: This study aimed to determine the reliability levels of the radiographic union scale for tibial fractures (RUST) and the modified version of the system, mRUST, for femoral shaft fractures in pediatric and adult patients and to evaluate the value of the scores for total and each cortex in the decision making on fracture union.

Methods: A total of 15 orthopedic surgeons scored the radiographs of 24 pediatric and 24 adult patients with femoral shaft fractures that were obtained at 0, 4, 8, 12, and 16 postoperative weeks treated with elastic stable intramedullary nail in pediatric patients and locked intramedullary nail in adult patients using the RUST and mRUST scores. Intra-class correlation coefficient (ICC) was used in the evaluation of reliability of the RUST and mRUST scores.

The effect of soft tissue interposition of the Endobutton on clinical results and on its postoperative migration after single-bundle anterior cruciate ligament reconstruction.

Can Breast Asymmetry Following the Treatment of Juvenile Idiopathic Scoliosis with Growing Rod Be Prevented? : A Preliminary Analysis.

Objective: It can be assumed that the progression of scoliosis in the juvenile period will increase the asymmetry in the rib cage, and thus will contribute to an increase in the breast asymmetry (BA) in the future. We are looking for answers to the questions; "How will the breasts look with respect to each other and what is the possibility of developing BA in the early follow-up period following the early surgical treatment and final fusion surgery of juvenile idiopathic scoliosis (JIS)?" For this reason, in this study, we aimed to evaluate the breast asymmetries of patients in the period after the final fusion.

Methods: Following growing rod treatment, final fusion was achieved in 12 females with JIS.

Few studies have evaluated the long-term functional and radiological outcomes of tarsal coalition resections. This study aimed to report and compare the functional and radiological outcomes after talocalcaneal (TC) and calcaneonavicular (CN) coalition resections. Thirty-three patients between 12 and 35 years old with symptomatic tarsal coalitions participated, each undergoing tarsal coalition resections (24 TC and 9 CN).

Comparison of clinical characteristics and 10-year survival rates of revision hip arthroplasties among revision time groups.

Introduction: No significant regression has been reported in revision total hip arthroplasty (THA) rates despite substantial progress in implant technologies and surgical techniques. It is critical to investigate how patient demographics, THA indications, surgical techniques, types of implants, and other factors influence the frequency of early and late revision surgery. The main purpose of the present study was to evaluate the clinical characteristics and 10-year survival rates of revision hip arthroplasties among revision time groups.

Methods: Twelve patients were operated using dual MCGR technique in one center, while 15 patients were operated using dual TGR technique for EOS in another center. Patients' demographic characteristics, complications and radiological measurements such as cobb angle, thoracic kyphosis, lumbar lordosis, T1-S1 range (mm), proximal junctional angle, distal junctional angle, sagittal balance, coronal balance, pelvic incidence, sacral slope and pelvic tilt were assessed and compared in preoperative, postoperative and last follow-up period.

Effectiveness of Using Photographs of the Change in Standing Posture on Postoperative Patient-Reported Satisfaction and Quality of Life.

Dissatisfaction is still an important problem in a small but important group of patients who undergo total knee arthroplasty. This study was designed to evaluate the effectiveness of showing patients the change in their standing posture, before and after total knee replacement, using standing photographs (anterior, posterior, and lateral view), on improving self-reported quality of life and satisfaction. Full-length lower extremity radiographs and standing photographs were obtained prior to total knee replacement and 6 months after surgery in the study group.
