BACKGROUND Poor reduction or neglect of an unstable carpal scaphoid fracture may lead to scaphoid nonunion or avascular necrosis. When pre-operative suggestion of avascular necrosis of the proximal pole is confirmed by intra-operative evaluation, conventional bone graft is not enough and a vascularized bone graft is strongly recommended. METHODS Five patients with nonunion of scaphoid fractur...

The purpose of this study was to review clinical and radiographic outcomes of perilunate dislocations and fracture dislocations treated with external fixation and K-wire fixation. Twenty patients (18 males and two females) with a mean age of 38 years (range 18-59) who had an acute dorsal perilunate dislocation or fracture dislocation were treated with the use of wrist external fixator and K-wir...

BACKGROUND Vascularized bone-grafting pedicled on 1,2 intercompartmental supraretinacular artery (1,2 ICSRA) has been recommended as a treatment alternative for established scaphoid nonunion complicated with proximal pole avascular necrosis (AVN). Previous reports focused the studies on the union rate and the revascularization of the transferred graft. However, the postoperative wrist stiffness...

The purpose of this study was to accurately quantify contralateral differences of the scaphoid in three-dimensional space to evaluate the feasibility of using the healthy contralateral bone as a reconstruction template in the preoperative planning of complex mal- or nonunions. Three-dimensional surface models of the left and right scaphoids were reconstructed from computed tomography images and...

conclusions although external fixation in open pediatric fractures and severe injuries is recommended, intramedullary nailing is also an effective method with low complications. combining pins and flexible intramedullary nails is effective in developing more stability and is not associated with more complications. background tibial fractures are the third most common pediatric long-bone fractur...

Abstract Background Treatment for distal diaphyseal or metaphyseal tibia fractures is challenging and the optimal surgical strategy remains a matter of debate. The purpose this study was to compare plate fixation with nailing in terms operation time, non-union, time-to-union, mal-union, infection, subsequent re-interventions functional outcomes (quality life scores, knee- ankle scores). Methods...

Background Scaphoid fractures are common carpal fractures that are often misdiagnosed as wrist sprains and may go on to nonunion. The location of the fracture site may influence the stability of scaphoid nonunions. Purpose To determine whether the stability of a scaphoid nonunion depends upon the fracture's location, we tested the hypothesis that a simulated fracture distal to the apex of the s...
