OBJECTIVES Despite the developments in chemotherapy protocols, improvement in the survival rates of osteosarcoma has been limited. We evaluated the effect of certain prognosis-related proteins on survival of patients with osteosarcoma. METHODS Data from 45 patients (24 males, 21 females) who were treated and followed-up for osteosarcoma were reviewed.(More)
BACKGROUND Osteosarcoma is a rare malignancy, and patients with this disease benefit from adjuvant chemotherapy. While cisplatin, anthracyclines and ifosfamide are the most commonly used agents in the treatment of osteosarcoma, a search for the best combination with higher efficacy and minimal toxicity continues. We planned to evaluate the efficacy of(More)
There are many drawbacks to using conventional approaches to the treatment of complex foot deformities, like the increased risk of neurovascular injury, soft-tissue injury, and the shortening of the foot. An alternative approach that can eliminate these problems is the Ilizarov method. In the current study, a total of 23 deformed feet in 22 patients were(More)
OBJECTIVES We investigated the agreement between the Blumensaat method and patellar height ratios and evaluated the reliability of the method in patellar height measurements. METHODS We retrospectively evaluated 105 digital knee x-rays of 77 patients (23 males, 54 females; mean age 32 years; range 21 to 62 years), whose radiographs were obtained at 30(More)
We reviewed 17 patients with distal intraarticular humeral type C fractures, treated by open reduction and internal fixation, followed by an early rehabilitation programme. The results, as judged by the criteria of Jupiter, were excellent in ten, good in five and fair in two. Non-union of the olecranon osteotomy occurred in one patient. Nous avons revu 17(More)
OBJECTIVES To compare 3 different fixation methods for the treatment of humeral shaft nonunions in terms of union time, functional outcome, and complications. DESIGN Retrospective case series. SETTING University hospital. PATIENTS Between 1996 and 2004, 80 patients (mean age, 49; range, 15 to 86; 30 women and 50 men) with nonunions of the humeral(More)
We compared time-dependent changes in the biomechanical properties of single-and double-row repair of a simulated acute tear of the rotator cuff in rabbits to determine the effect of the fixation techniques on the healing process. A tear of the supraspinatus tendon was created in 80 rabbits which were separated into two equal groups. A single-row repair(More)
BACKGROUND Transfer of the latissimus dorsi tendon to the posterosuperior part of the rotator cuff is an option in active patients with massive rotator cuff tears to restore shoulder elevation and external rotation. However, it is unknown whether this treatment prevents progression of cuff tear arthropathy. QUESTIONS/PURPOSES The purpose of this study was(More)
OBJECTIVES Although conventional suture techniques yield satisfactory results in the treatment of meniscal ruptures, they are inherent with long operative time and high complication rates. The purpose of this study was to evaluate the results of meniscal repair with the use of the RapidLoc device. METHODS The study included 57 consecutive patients (all(More)
The American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form (ASES) is a standard shoulder assessment form, which is comprised of objective and subjective sections and prepared by shoulder and elbow surgeons. The purpose of this study was to translate the subjective part of the ASES into Turkish and establish its cultural adaptiveness and(More)
