Publication Metadata only Comparison of 3 Cell-Free Matrix Scaffolds Used to Treat Osteochondral Lesions in a Rabbit Model.(2022-03-30T00:00:00Z) Ucan, Vahdet; Pulatkan, Anil; Yilmaz, Bengi; Tahmasebifar, Aydin; Tok, Olgu Enis; Tuncay, Ibrahim; Elmali, Nurzat; Ozturk, Burak Yagmur; Uzer, GÖKÇER; UÇAN, VAHDET; TUNCAY, İBRAHİM; UZER, GÖKÇERPublication Metadata only Biomechanical Comparison of 2 Different Femoral Stems in the Shortening Osteotomy of the High-Riding Hip(2016-06-01) Tuncay, Ibrahim; Yildiz, FATİH; Bilsel, Kerem; Uzer, GÖKÇER; Elmadag, Mehmet; Erden, TUNAY; Bozdag, Ergun; TUNCAY, İBRAHİM; YILDIZ, FATİH; BİLSEL, İSMAIL KEREM; UZER, GÖKÇER; ELMADAĞ, NUH MEHMET; ERDEN, TUNAYBackground: We hypothesized that a rectangular cross-sectional femoral stem may produce more initial stability of the transverse subtrochanteric femoral shortening osteotomy rather than a circular cross-sectional stem.Publication Metadata only Reliability of magnetic resonance imaging versus arthroscopy for the diagnosis and classification of superior glenoid labrum anterior to posterior lesions(2017-02-01) Yildiz, FATİH; Bilsel, Kerem; PULATKAN, Anil; Uzer, GÖKÇER; Aralasmak, AYŞE; ATAY, Musa; YILDIZ, FATİH; BİLSEL, İSMAIL KEREM; UZER, GÖKÇER; ARALAŞMAK, AYŞEThe physical examination of the shoulder is usually not reliable for the true diagnosis of superior glenoid labrum anterior to posterior (SLAP) lesions. Magnetic resonance imaging (MRI) has been routinely used for the diagnosis. This prospective study investigates the radiological diagnosis of the SLAP lesions and compares accuracy of arthroscopic and MRI classifications.Publication Open Access Comparison of two types of proximal femoral hails in the treatment of intertrochanteric femur fractures(2015-09-01) Uzer, GÖKÇER; Elmadag, NUH MEHMET; Yildiz, FATİH; Bilsel, Kerem; Erden, TUNAY; Toprak, HÜSEYİN; UZER, GÖKÇER; ELMADAĞ, NUH MEHMET; YILDIZ, FATİH; BİLSEL, İSMAIL KEREM; ERDEN, TUNAY; TOPRAK, HÜSEYİNBackground: Hip nailing is frequently used to treat unstable intertrochanteric femoral fractures (ITF) in elderly patients. In this retrospective study, we compared the functional and radiological results, and the complications, of patients treated using proximal femoral nails (PFN) with an integrated, interlocking, compression lag screw, or two separate lag screws, which allow linear compression at the fracture site. Methods: A total of one hundred and eighteen patients were operated on for AO/OTA 31-A2 ITF between May 2010 and April 2012, and eighty-two of these patients, for whom sufficient follow-up data and documentation were available, were included into the study. PFNs with interlocking, integrated lag screws (Group I) were used in forty-four patients, and PFNs with two separate lag screws (Group II) in thirty-eight. Outcome parameters were the extent of varus collapse and leg length discrepancy on radiographs, and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) and Harris hip scores (HHS) as functional results. Results: Mean follow-up duration was 20 months (range, 12-36 months); fractures healed in all patients. Mean varus collapse values were 2.03±5.68° and 5.21±5.27° (p=0.01), Harris hip scores 73.2±11.65 and 74.72±11.15 (p=0.54), and WOMAC scores 70.78±11.41 and 71.78±11.19 (p=0.69) in Groups I and II, respectively. No difference was detected between the groups in terms of outcome parameters or complication rate. Conclusion: In the treatment of ITF, PFNs with an integrated, interlocking, compression lag screw, or two separate lag screws did not differ in terms of functional and radiological results or complication rate.Publication Metadata only Evaluation of postural control in children with increased femoral anteversion.(2022-04-16T00:00:00Z) Tuncer, Deniz; Gurses, Hulya Nilgun; Senaran, Hakan; Uzer, GÖKÇER; Tuncay, Ibrahim; TUNCER, DENİZ; GÜRSES, HÜLYA NILGÜN; ŞENARAN, HAKAN; UZER, GÖKÇER; TUNCAY, İBRAHİMPublication Metadata only Comparison of four different techniques for performing an osteotomy A BIOMECHANICAL, RADIOLOGICAL AND HISTOLOGICAL STUDY ON RABBITS TIBIAS(2015-12-01) Elmadag, M.; Uzer, GÖKÇER; Yildiz, FATİH; ERDEN, TUNAY; Bilsel, K.; Buyukpinarbasili, NUR; USUMEZ, A.; BOZDAG, E.; SEN, C.; ELMADAĞ, NUH MEHMET; UZER, GÖKÇER; YILDIZ, FATİH; ERDEN, TUNAY; BİLSEL, İSMAIL KEREM; BÜYÜKPINARBAŞILI, NURThis animal study compares different methods of performing an osteotomy, including using an Erbium-doped Yttrium Aluminum Garnet laser, histologically, radiologically and biomechanically. A total of 24 New Zealand rabbits were divided into four groups (Group I: multihole-drilling; Group II: Gigli saw; Group III: electrical saw blade and Group IV: laser). A proximal transverse diaphyseal osteotomy was performed on the right tibias of the rabbits after the application of a circular external fixator. The rabbits were killed six weeks after the procedure, the operated tibias were resected and radiographs taken.Publication Open Access Safety of modified Stoppa approach for Ganz periacetabular osteotomy: A preliminary cadaveric study(2016-08-01T00:00:00Z) Elmadag, Mehmet; Uzer, GÖKÇER; Yildiz, FATİH; CEYLAN, Hasan H.; Acar, Mehmet A.; ELMADAĞ, NUH MEHMET; UZER, GÖKÇER; YILDIZ, FATİHObjective: The aim of this cadaveric study was to investigate the efficacy of the modified Stoppa approach in Ganz periacetabular osteotomy (PAO). Methods: The Ganz PAO was performed on 10 hemipelvises with normal hips, from 5 cadavers using the modified Stoppa approach through the Pfannenstiel incision. All of the osteotomies were performed under fluoroscopic control and direct visualizing the osteotomy site from the same incision. After the osteotomy, the acetabulum was medialized and redirected anterolaterally, and fixed with 2 screws. The neurovascular structures and the joints were examined by dissecting the soft tissues after fixation of the osteotomies. Outcome parameters were center-edge (CE) angle, the distances between the osteotomy and anterior superior iliac spine (ASIS), and between the osteotomy and the sciatic notch, neurovascular and joint penetrations. Results: After the osteotomy, the mean CE angle was improved from 19.8 degrees to 25.2 degrees, mean distance between the osteotomy and ASIS was 3.1 cm, and the mean distance between the osteotomy and the sciatic notch was 10.2 mm. The neurovascular structures and the joints were examined by dissecting the soft tissues after fixation of the osteotomies. No damage to the joint, surrounding arteries, veins or nerves was detected in any of the cadavers. Conclusions: Bilateral dysplastic hips can be treated with a 10 cm, cosmetically more acceptable incision in the same session using this approach. Quadrilateral surface of the acetabulum can be directly seen using this approach and the osteotomy can be safely performed. (C) 2016 Turkish Association of Orthopaedics and Traumatology.
