When undertaking surgery for nonunion of scaphoid fractures, appreciation of the three dimensional (3D) anatomy and hence accurate restoration of the original shape of the bone is difficult. Computerised tomography (CT) is regularly used to evaluate scaphoid nonunions slice by slice before surgery. As a potential aid for surgical planning, we have developed a method for producing 3D printed ana...

Fusion between the os centrale and the scaphoid has played a central role in many functional and phylogenetic interpretations of hominoid evolution. In particular, scaphoid-centrale fusion shared among African apes and humans has been interpreted as an adaptation in knuckle-walkers, an exaptation in hominins, and has been offered as evidence for a knuckle-walking origin of bipedalism. However, ...

BACKGROUND The medial and lateral femur provide a source of convex osteochondral vascularized bone. The medial trochlea has been demonstrated to have similar contour to the proximal scaphoid, lunate, and capitate. Other sites of osteochondral harvest such as the posteromedial femur and the lateral trochlea are similar in morphology to the humeral capitellum and medial talus, respectively. These...

this study was performed to evaluate the results of 14 years of application of ilizarov method in treatment of infected non-:union:s of tibia and femur in patients with severe trauma and battlefield wounds. seventeen patients with long bone non:union: (14 were with infected non:union: of tibia out of whom two were associated with tibial bone defects and 3 with infected non-:union: of femur) wer...

The authors compare the functional outcome of 8 patients treated by distal scaphoid resection arthroplasty for scaphoid nonunion with symptomatic wrist arthritis before surgery and after a minimum follow-up of 6 months. There was a significantly better range of radial deviation and grip strength at the time of re-examination. Significantly fewer patients complained of resting pain. By contrast ...

Introduction: Internal fixation used as treatment for scaphoid fractures has increased with advances in surgical techniques [1]. Proximal pole scaphoid fractures present a clinical challenge due to their lower success rate when cast immobilization and internal fixation are utilized [2]. Screws maximizing length have been shown to impact wrist motion for fixed scaphoid waist fractures [3]. Addit...

UNLABELLED Trans-scaphoid perilunate fracture-dislocation is the most common variety of fracture-dislocations of the wrist. Because of the carpal scaphoid fracture association, post-reduction stability is poor, often requiring surgery. Of the several surgical techniques used over time, percutaneous screw fixation for scaphoid fracture is currently preferred. MATERIAL AND METHODS Six cases of ...

BACKGROUND Our aim is to study the accuracy of emergency medicine (EM) physician-performed, bedside ultrasonography (BUS) in patients with clinical suspicion of scaphoid fracture and normal radiographs. METHODS From January to December 2011, an EM physician used BUS to prospectively evaluate patients presenting to the emergency department (ED) with clinical suspicion of scaphoid fracture and ...
