Aims. The aim of this randomized trial was to compare the functional outcome of two different surgical approaches to the hip in patients with a femoral neck fracture treated with a hemiarthroplasty. Patients and Methods. A total of 150 patients who were treated between February 2014 and July 2017 were included. Patients were allocated to undergo hemiarthroplasty using either an

Background. Cartilage lesions in chronic lateral ligament deficiency are common with the incidence rates mentioned in the previous literature up to 30%. However, other intra-articular pathologies in the unstable ankle have received little attention.

Introduction. Most Japanese patients who receive total hip arthroplasty (THA) are osteoarthritic and 70% have development dysplasia of the hip. Their stature is shorter than average and their sizes (acetabular cup and femoral stem) are smaller. The Taperloc Microplasty (BIOMET) is a short femoral stem. It was launched on July 2012 in Japan (extended on January 2013). It is essentially a shortened version of the Taperloc stem (35mm shorter than the standard stem). Objectives. We aimed to evaluate the outcomes of minimally invasive
Introduction. In the setting of periprosthetic joint infection, the complete removal of implants and cement can be challenging with well-fixed, cemented implants about the knee. This can get especially complex in the setting of long cemented femoral stems. Osteotomies are well described in the proximal femur and tibia for removal of implants and cement. There is little information available on distal femoral osteotomies to facilitate knee implant and retained cement removal. Methods. We describe a novel
Introduction. Since2007, we have used CT-based fluoroscopy-matching navigation system (Vector Vision Hip Ver.3.5.2, BrainLAB, Germany) in Total hip arthroplasty. This system completes the registration procedure semi-automatically by matching the contours of fluoroscopic images and touching 3 adequate points to the contours of 3D bone model created in the computer. Registration procedure using fluoroscopic figures has finished before making surgical incision. It needs no elongation time during the operation. The accuracy of navigation system depends on the techniques of registration used for the navigation and secure fixation of the dynamic reference markers. These could be affected by the different type of approaches. The objective of this study was to evaluate the accuracy of CT-based fluoroscopy-matching navigation system in THA and compare the cup position by
Background: In order to achieve a minimized need for tissue dissection resulting in a faster rehabilitation, minimally invasive surgery (MIS) in Total Hip Arthroplasty (THA) was developed. In this small incision technique the skin and musle dissection has been reduced with respect to the classical approach. Literature shows ambiguous results comparing the posterolateral minimally incisive with the classical approach. As the
Purpose: The purpose of our retrospective analysis was to describe results of arthroscopic treatment of painful ankle instability without clinical or radiological laxity. Material and methods: Eighteen patients, mean age 27 years (seven men and nine women) were operated on by the same surgeon between 1999 and 2000. Sixteen patients (90%) were reviewed by an independent investigator at 20±4 months. Fifteen patients were athletes, ten at the competition level, and five had amateur sports activities. The accident caused forced inversion in 15/16 cases, during sports activities in 85.5% of the cases. Mean age at injury was 17±6 years. Mean time between the accident and arthroscopy was eight years. All patients had pain in the
