BACKGROUND Angle-stable locking plates have improved the surgical management of fractures. However, locking implants are costly and removal can be difficult. The aim of this in vitro study was to evaluate the biomechanical performance of a newly proposed crossed-screw concept ("Fence") utilizing conventional (non-locked) implants in comparison to(More)
BACKGROUND Bone density is an important factor in the management of fractures of the distal radius. OBJECTIVES The aim of this study was to establish whether standard anteroposterior (AP) radiographs would provide the attending physician with a prediction of bone density. PATIENTS AND METHODS Six pairs of human cadaveric radii were harvested. The mean(More)
Fusion of the first tarsometatarsal joint is a widely used procedure for the correction of hallux valgus deformity. Although dorsomedial H-shaped plating systems are being increasingly used, fusion can also be achieved by plantar plating. The goal of the present study was to compare these 2 operative techniques based on the anatomic considerations and show(More)
BACKGROUND Volar locking plate fixation has become the gold standard in the treatment of unstable distal radius fractures. Juxta-articular screws should be placed as close as possible to the subchondral zone, in an optimized length to buttress the articular surface and address the contralateral cortical bone. On the other hand, intra-articular screw(More)
INTRODUCTION Distal comminuted femoral fractures with joint involvement are highly challenging for the surgeon. We present a potential therapeutic concept that aims especially at the treatment of posttraumatic leg length discrepancy. CASE PRESENTATION This case report describes a polytraumatized 19-year-old German woman. Among other injuries she had a(More)
BACKGROUND Screw fixation of pelvic ring fractures is a common, but demanding procedure and navigation techniques were introduced to increase the precision of screw placement. The purpose of this case series was the evaluation of screw misplacement rate and functional outcome of percutaneous screw fixation of pelvic ring disruptions using a 2D navigation(More)
Tibiocalcaneal arthrodesis may be the only means of obtaining a painless and stable limb when there is loss of the talus. We present the early results of a prospective study on tibiocalcaneal arthrodesis using a latest-generation retrograde intramedullary nail. In the period 2006-2007, nine patients underwent tibiocalcaneal arthrodesis with retrograde(More)
INTRODUCTION The ilio-inguinal approach has come to be used routinely in the management of acetabular fractures involving the anterior wall. Thrombotic complications following surgery via this route are a serious, but rare, complication. CASE PRESENTATION We report the case of a 66-year-old male patient who slipped on an icy pavement and fell on his left(More)
INTRODUCTION Many different techniques have been proposed for tibiotalocalcaneal fusion (TTCF). Fixation may be obtained with screw constructs , plates, external fixators and in-tramedullary (IM) nails [1,2]. The compression , stable fixation, correct hindfoot alignment , and apposition of well-vascularized bony surfaces resulting in sound bony union and a(More)
m Implantation of posterior ch.unber lenses (intmcalar lens = IOL) is an established method to replace opaque lenses. Prefered positioning of implanted lenses is in the capsular bag. either with or without touching the posterior capsule. Purpose of the present study is to determine the real position of the implanted lens in relation to the posterior capsule(More)
