AIM To investigate whether nerve regeneration can be induced in the tubular bone between distal and proximal cut nerve ends. MATERIAL AND METHODS Twenty adult Wistar rats were used for the study. Rats were divided into three groups; femoral bone conduit group, nerve transection group, sham group. The sciatic nerve was surgically cut and from both ends inserted into the adjacent femoral bone t...

OBJECTIVES This study aims to investigate discrepancy between posterior condylar axis (PCA)+3 degree external rotation (ER) line and clinical transepicondylar axis (cTEA) line and consistency between the both techniques in primary total knee arthroplasty. PATIENTS AND METHODS Thirty-six knees [Bilateral knees were operated simultaneously in 12 patients (50%)] in 24 patients [3 men (12.5%), 21...

Introduction The following question is often asked: why does the measured resection technique result in a balanced total knee replacement despite measuring from an eburnated joint surface distally and a cartilage-covered condyle posteriorly. The presented hypothesis is that the distal femoral bone-cut is distalised on average by 2 mm when measured relative to the medial condyle. This is due to ...

The fixation of distal femoral fractures (Vancouver type-C fractures) following a well-fixed hip arthroplasty femoral stem has become a challenging issue for orthopedic surgeons due to the inter-prosthetic biomechanical effects such as negative, positive, and torsional strain. Surgeons have applied a range of constructs to overcome these difficulties. To minimize the risk of inter-prosthetic fr...

this study planned for finding the agreement dxa and quantitative ultrasound (qus) of phalanx in osteoporosis diagnosis and cut off point of qus for osteoporosis diagnosis in postmenopausal women. in 180 postmenopausal women, bmd of axial regions with dxa (dpx-md, ge, lunar, usa) and phalanx with qus (dbm-sonic 1200) measured. agreement of methods and cut off for qus in defining osteoporosis ob...

BACKGROUND Unstable proximal femoral fractures are common and challenging for the orthopaedic surgeon. Often, these are treated with intramedullary nails. The most common mode of failure of any device to treat these fractures is cut-out. The Synthes proximal femoral nail antirotation (PFNA) is unique because it is the only proximal femoral intramedullary nail which employs a helical blade in li...

Background:   To compare the results of two different ways of distal femoral osteotomy stabilization in patients suffering from genuvalgum: internal fixation with plate, and casting. Methods:   In a non-randomized prospective study, after distal femoral osteotomy with the zigzag method, patients were divided into two groups: long leg casting, and internal fixation with blade plate. For all pati...
