OBJECTIVE The aim of this study was to evaluate the outcome of patients undergoing limb lengthening using motorized intramedullary nails. METHODS This study included eleven femora and 4 tibiae from 14 patients (9 male, 5 female; mean age: 26.9 years; range: 14 to 51 years) who underwent limb lengthening using motorized intramedullary femoral nails(More)
OBJECTIVE The aim of this study was to analyze the results and complications of simultaneous bilateral femoral and tibial lengthening in achondroplastic patients. METHODS The study included the 44 femora and 44 tibiae of 22 achondroplastic patients (16 females, 6 males; mean age: 6.36 years, range: 3 to 11 years) that underwent simultaneous lengthening.(More)
OBJECTIVE The aim of this study was to investigate the effects of demineralized bone matrix (DBM) on tendon-bone healing. METHODS The extensor digitorum longus tendon was fixed with pegged suture technique in a tunnel at the proximal tibia in both legs of 12 New Zealand rabbits. Rabbit DBM was applied in the tunnel on the right limbs before fixation(More)
OBJECTIVE The aim of the study was to assess the early outcomes of the arthroscopic treatment of femoroacetabular impingement. METHODS Forty-two femoroacetabular impingement (FAI) patients (mean age: 35.1 years, range: 16 to 52 years) treated arthroscopically between 2006 and 2011 in our clinic were retrospectively analyzed. Twenty-five patients had Cam,(More)
To investigate anatomic relation of standard and coaxial ankle arthroscopy portals with neurovascular structures during different degrees of ankle motion. Twenty posterior ankles of ten fresh cadavers were assessed. Posteromedial, posterolateral and coaxial (transmalleolar) portals were created using 4-mm Steinmann pins in accordance with the defined(More)
OBJECTIVE The purpose of this study was to summarize our clinical results with distraction osteogenesis for the treatment of infected tibial nonunion around the ankle joint. METHODS Between 1994 and 2009, 13 patients with a mean age of 50 years (range: 27-79 years) underwent tibial reconstruction for the treatment of infected nonunion of the distal tibia,(More)
Oxidized zirconium (Oxinium™; Smith & Nephew, Memphis, TN, USA) articulated with polyethylene in total hip arthroplasty (THA) appeared to have the potential to reduce wear dramatically. The thermally oxidized metal zirconium surface is transformed into ceramic-like hard surface that is resistant to abrasion. The exposure of soft zirconium metal under hard(More)
BACKGROUND The results of cementless stems in total hip arthroplasty (THA) done because of congenital dislocation with step-cut osteotomy is not well known, particularly the influence of the design and the role of extent of porous coating. Therefore we performed a retrospective study to evaluate the mid to long-term results THA performed with a single type(More)
OBJECTIVE To investigate the relationship between injury patterns, complications, and the functional outcomes of patients with proximal-ulna fracture-dislocations. METHODS Retrospective analysis of 15 patients (10 men, 5 women; mean age, 49.1 years; mean follow-up 49 months) with 6 anterior and 9 posterior fracture-dislocations of the proximal ulna. The(More)
BACKGROUND Various types of shortening osteotomies and prosthesis are used for femoral reconstruction in total hip arthroplasty of the high hip dislocation. This biomechanical study investigates whether step-cut osteotomies result in better stability than oblique osteotomies and cylindrical femoral stems enhance stability of the osteotomy more than conical(More)
