Patients and methods Between January 2012 and June 2013, eight patients (mean age 62.6; range 48–84 years) with comminuted proximal humeral fractures extending to the humeral head and one-third proximal diaphysis were treated with CREF using hybrid-type EFs. Functional results were evaluated in terms of shoulder ranges of movement, Constant, DASH, and VAS scores, and radiological results were evaluated using antero-posterior and lateral radiograms of the treated humerus. Results The mean follow-up was 16.6 (range 12–28) months. The mean fixator time was 84 (range 63–118) days. The mean range of forward flexion, internal rotation, external rotation, and abduction were 145°, 61.2°, 65°, and 115°, respectively. The mean Constant, DASH, and VAS scores were 79.8, 10, and 1.75, respectively. Seven of the eight patients (87.5 %) healed radiologically. Two complications were observed in two patients: non-union and superficial pin site infection. Conclusions In the treatment of unusual, comminuted proximal diaphyseal humeral fractures, CREF using a hybrid-type EF is a minimally invasive, advantageous procedure with acceptable rates of healing, low risk of surgical site infection, and early range of motion. Level of evidence Level IV, case series.Publication Metadata only HUMERUS ÜSTUÇ KIRIĞI NEDENİYLE OTOGREFT KULLANILARAK VEYA KULLANILMADAN TERS OMUZPROTEZİ YAPILAN HASTALARININ SONUÇLARI(2017-01-10) UZER, GÖKÇER; YILDIZ, FATİH; BİNLAKSAR, RUWAİS; ELMADAĞ, NUH MEHMET; KUŞ, GAMZE; BİLSEL, İSMAİL KEREM; UZER, GÖKÇER; YILDIZ, FATİH; ELMADAĞ, NUH MEHMET; BİLSEL, İSMAIL KEREMPublication Metadata only Süperior kapsül rekonstrüksiyonunda hücresiz insan dermal grefti ve tensor fasya lata otogreftinin karşılaştırılması: Tavşan modelinde histolojik ve biyomekanik çalışma(2018-03-24) YILDIZ, FATİH; BİLSEL, İSMAİL KEREM; PULATKAN, MEHMET ANIL; KAPICIOĞLU, MEHMET; UZER, GÖKÇER; ÇETİNDAMAR, TOLGA; SÖNMEZ, CAVİDE; BOZDAĞ, SÜREYYA ERGÜN; SÜNBÜLOĞLU, EMİN; YILDIZ, FATİH; BİLSEL, İSMAIL KEREM; KAPICIOĞLU, MEHMET; 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 Metadata only All-arthroscopic, Guideless Single Suture-button Fixation of Acute Acromioclavicular Joint Dislocation: A Description of the Technique and Early Treatment Results(2017-06-01) ALTINTAŞ, BURAK; YILDIZ, FATİH; UZER, GÖKÇER; KAPICIOĞLU, MEHMET; BİLSEL, İSMAİL KEREM; YILDIZ, FATİH; UZER, GÖKÇER; KAPICIOĞLU, MEHMET; BİLSEL, İSMAIL KEREMPublication 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 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.
