    Isokinetic Evaluation of Shoulder Strength and Endurance after Reverse Shoulder Arthroplasty: A Comparative Study
    (TURKISH ASSOC ORTHOPAEDICS TRAUMATOLOGY, 2019-01-01) Ersen, Ali; Birisik, Fevzi; Bayram, Serkan; Sahinkaya, Turker; Demirel, Mehmet; Atalar, Ata Can; Demirhan, Mehmet
    Objective: The present study aimed to compare the isometric strength and endurance of shoulder abduction and internal and external rotation between operated shoulders and nonoperated, contralateral shoulders of patients who underwent reverse shoulder replacement due to unilateral rotator cuff tear arthropathy. Patients and methods: With a diagnosis of cuff tear arthropathy, 41 consecutive patients (mean age of 70.8 years

    Autologous segmental tibia bone transfer in the treatment of distal tibia Gustilo-Anderson type-III open fracture: A case report
    (ELSEVIER SCI LTD, 2016-01-01) Demirel, Mehmet; Akgul, Turgut; Polat, Gokhan; Cakmak, Mehmet Fevzi; Dikici, Fatih
    INTRODUCTION: We present the results of a two-stage reconstruction performed with autologous segmental tibia bone transfer on a distal tibia Gustilo-Anderson type-IIIC open fracture in this paper. Our aim is to discuss the results of this surgery, potential failures and complications in our procedures, and ways to protect against osteolysis. PRESENTATION OF CASE: A 20-year-old male who has undergone surgery in our clinic for a Gustilo-Anderson type-III open fracture of the left tibia using autologous tibia segmental bone transfer. The first operation consisted of removing the exposed bony fragment and placing it in the abdominal wall. Fifty days after the first operation, an intramedullary nailing operation was performed using the autologous bone fragment kept in the abdominal wall. Before the final procedure, we assessed the viability of the bone fragment using scintigraphy as well as the paprika sign was observed on the fragment during operation. Patient was seen in follow-up every three weeks to evaluate for successful osteosynthesis

    Posterior Approach Alone Versus Combined Anterior and Posterior Approach in the Management of Vertebral Tuberculosis
    (TURKISH NEUROSURGICAL SOC, 2019-01-01) Demirel, Mehmet; Akgul, Turgut; Pehlivanoglu, Tuna; Karademir, Gokhan; Bayram, Serkan; Dikici, Fatih; Sar, Cuneyt
    AIM: To compare posterior surgery alone versus combined anterior and posterior surgery for the management of spinal tuberculosis. MATERIAL and METHODS: Data from 31 consecutive patients who underwent surgery for spinal tuberculosis were analyzed retrospectively. Patients were divided into two groups as group A (posterior surgery alone) or group B (combined anterior and posterior surgery), and groups were compared in terms of invasiveness of the procedure, spinal deformity, fusion, neurological status, and postoperative complications. RESULTS: Group A included 16 patients (mean age: 56 years, range: 29-75) with a mean follow-up period of 29 months (range 12-60) while group B included 15 patients (mean age: 60 years, range: 35-73) with a mean follow-up period of 28 months (range 12-60). Procedurally, average operation time and mean length of hospitalization were shorter, and mean blood loss was lower in group A (p<0.05) compared to group B. Postoperative bone fusion took significantly (p<0.05) longer time in group A (10.5 +/- 2.1 months)than in group B (9.3 +/- 3.1 months), and all patients with a neurological deficit recovered completely during the postoperative period. No significant differences were observed between two groups with respect to postoperative complications (p>0.05). CONCLUSION: Combined anterior-posterior surgery may not be required for treating vertebral tuberculosis as posterior surgery alone appears to be sufficient.
