Abstract For the percutaneous fixation of scaphoid fractures, navigated approaches have been proposed to facilitate screw placement. Based on ultrasound imaging, navigation can be carried out in a cost-effective and fast manner, furthermore avoiding harmful radiation. this purpose, efficient architecture for automated segmentation bone volume images is needed. Methods: 2D scaphoid, two architec...

PURPOSE The purpose of this study was to simulate and calculate the probability of iatrogenic perforation of the scaphoid cortical bone when internal fixation appeared to be safe on radiographs. The results will assist surgeons in determining proper screw placement. METHODS Thirty scaphoids were reconstructed using computed tomography data and image-processing software. Different central axes...

Patients with wrist pain commonly present with an acute injury or spontaneous onset of pain without a definite traumatic event. A fall onto an outstretched hand can lead to a scaphoid fracture, which is the most commonly fractured carpal bone. Conventional radiography alone can miss up to 30 percent of scaphoid fractures. Specialized views (e.g., posteroanterior in ulnar deviation, pronated obl...

PURPOSE The present study is a review of patients with scaphoid non-unions treated with a dorsal vascularized bone graft. The study highlights a subset of patients incorrectly diagnosed as graft failures. METHODS A retrospective review of patients who received vascularized grafts for scaphoid nonunions was performed over a four-year period. The vascularized graft of choice for this group was ...

A study was performed to analyse the morphometry and morphological variants of adult scaphoid bone in Sikkimese population of North Eastern India. The study included 100 dry human scaphoid bones. The bones which had previous signs of fracture were excluded. The morphometric parameters were measured with vernier caliper of 0.02 mm accuracy; the circumferences were measured by placing a thread ar...

Introduction Scaphoid fractures are the most common type of hand fracture. Traditionally, non-displaced fractures of the scaphoid have been treated conservatively, with the immobilisation of the hand with a cast; hence, surgical fixation of the fracture has become increasingly popular because of quicker re-mobilisation and return to its original function. However, this was balanced against the ...

PURPOSE To assess the results of a hybrid Russe procedure using a corticocancellous strut, cancellous autologous nonvascularized bone graft, and cannulated headless compression screw to reduce the deformity reliably from a collapsed scaphoid nonunion, provide osteoinductive stimulus, and stabilize the fracture for predictable union. METHODS A hybrid Russe procedure was performed for scaphoid ...

Scaphoid fractures as frequently overseen injuries often result in scaphoid non-unions, that need to be treated to prevent carpal collapse and secondary cartilage damage. Vital bone tissue and compression of fracture and bone graft ends seem to be crucial in for ossification and final bone healing. In the present study we compare our results using a high compression screw (HCS Synthes(®)) to re...
