The scaphoid is the most commonly fractured bone in the carpus. Although greater than 90% of scaphoid fractures unite with cast immobilization, failure to heal remains a clinical reality, particularly when the fracture is displaced or associated with intracarpal instability [1–3]. Dabezies [4] reported a 55% incidence of nonunion and a 50% rate of proximal pole avascular necrosis (AVN) in scaph...
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...
The nutrient vascular foramina of scaphoid bone were observed and clinical interpretations were discussed. The 220 dry scaphoid bones of adult age group were studied. The vascular foramina distal to mid of waist were 1 to 2 in 17.72 % specimen and rest of 82.28% bones had more then 2 foramina. There was no scaphoid without vascular foramina distal to mid of waist of scaphoid. But the proximal p...
The aim of this review was to present currently available evidence on the management of acute scaphoid fractures. Acute scaphoid fractures are usually diagnosed by a combination of history, physical examination, and radiography. However, in many patients scaphoid fractures are still missed. Thus, the general trend is to over-treat patients with a suspicion of scaphoid fracture. Many aspects of ...
Fractures of the scaphoid bone mainly occur in young adults and constitute 2-7% of all fractures. The specific blood supply in combination with the demanding functional requirements can easily lead to disturbed fracture healing. Displaced scaphoid fractures are seen on radiographs. The diagnostic strategy of suspected scaphoid fractures, however, is surrounded by controversy. Bone scintigraphy,...
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...
PURPOSE To examine the effects of scaphoid retention, inclusion, and excision on wrist motion and radiolunate contact characteristics in a cadaveric model after simulated 4-corner fusion with rigid internal fixation. METHODS Seven fresh-frozen cadaveric upper extremities were examined. For all surgical manipulations the motion was measured and contact characteristics were assessed using ultra...
Operative management of nonunion scaphoid fracture in children: a case report and literature review.
Scaphoid fractures are uncommon in children, but if maltreated, they can result in nonunion. The authors report a case of left scaphoid nonunion in an 11-year-old boy. The operative management of this pseudarthrosis was performed (K-wire fixation and bone grafting of scaphoid). After a 10-month follow-up period, the left wrist regained a full range of motion with no impairment. The roentgenogra...
SCAPHOID FRACTURES account for 71% of carpal bone fractures, and between 2% and 7% of all orthopaedic fractures (Nishihara 2000). This type of injury also accounts for one in every 10,000 attendances annually in UK emergency departments (EDs) (Tai and Ramachandran 2005). Between 5% and 12% of scaphoid fractures are related to other fractures (Malik et al 2010). The scaphoid is one of the eight ...
Stress fracture of the carpal scaphoid is very rare. We present stress fracture of the scaphoid in an adolescent gymnast who was treated with internal fixation. Key pointsThere is a risk of stress fracture of the scaphoid in gymnast.Internal fixation with a screw is one of the good options for stress fracture of the scaphoid.
