BACKGROUND *Equal contributors.Planar bone scintigraphy (PBS) is often advocated for diagnosing occult scaphoid fractures. PBS is a sensitive diagnostic modality, but lacks specificity, which may result in over-diagnosis. PURPOSE To examine, in a pilot study, the potential additional value of single photon emission computed tomography (SPECT) combined with low dose computed tomography (CT) fo...

We have assessed the value of using a simple apparatus,the Carpal Box, in patients with suspected scaphoid fracture, to produce elongated and magnified radiographs of the carpus. The interobserver agreement between 60 observers of standard scaphoid radiographs and longitudinal and transverse Carpal Box radiographs (X-CB) was compared in 11 patients. Three-phase bone scanning was used as a compa...

background scaphoid fractures are the most common type of carpal fractures. objectives the aim of the study was to compare the diagnostic value of panoramic and conventional radiographs of the wrist in scaphoid fractures. patients and methods the panoramic and conventional radiographs of 122 patients with acute and chronic wrist trauma were studied. the radiographs were analyzed and examined by...

INTRODUCTION Scaphoid fractures are rare in childhood. Diagnosis is very difficult to establish because carpal bones are not fully ossified. In suspected cases comparative or delayed radiography is used, as well as computerized tomography, magnetic resonance imaging, ultrasound and bone scintigraphy. Majority of scaphoid fractures are treated conservatively with good results. In case of delayed...

The aim of this study was to evaluate the number and distribution of fractures around the wrist found on bone scintigraphy in patients with a clinically suspected scaphoid fracture and negative initial radiographs. We retrospectively included 445 consecutive patients with a suspected scaphoid fracture who underwent routine bone scintigraphy. None of the radiographs showed evidence of a fracture...

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...

BACKGROUND Negative ulnar variance can be a risk factor in Kienböck's disease, wrist instability, and scaphoid bone fracture. This study focused on the ulnar variance in wrists with scaphoid bone nonunion. METHODS We retrospectively reviewed posteroanterior wrist radiographs of 65 patients who were diagnosed as established scaphoid nonunion and underwent open reduction and bone grafting betwe...

Scaphoid, the boat-shaped carpal bone, is largely covered by articular cartilage. It has a much more complex arterial supply than previously reported, moreover, this pattern been hypothesized to lead avascular necrosis after fracturesScaphoid blood long documented as scarce; it arises from radial artery giving palmar and dorsal branches. There high-grade evidence reporting two main arteries ent...

Internal fixation of scaphoid fractures avoids the problems associated with prolonged plaster immobilization and, at the same time, allows an early return to activity for these mostly young patients.Internal fixation of the scaphoid is greatly facilitated by the use of specially designed headless bone screws, such as the Herbert bone screw, originally developed specifically for internal fixatio...

The scaphoid is the second largest of the carpal bones and is named due to its boat-like shape (derived from the Greek word scaphon). It is situated laterally in the proximal carpal row, articulating with the distal radius proximally and forms joints with the lunate, capitate, trapezoid and trapezium. The scaphoid can be divided into proximal, mid and distal thirds for ease of description. The ...
