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...

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.

The movements of the carpal bones during the scaphoid shift test were evaluated radiographically in 60 wrists. The clinical results were graded according to the degree of subluxation of the scaphoid and pain on the dorsum of the wrist. Lateral radiographs at rest and under stress were taken and the relative movements of the scaphoid with respect to the radius and lunate, and the rotation of the...

CONTEXT The scaphoid is the most commonly fractured bone in the wrist and can often be difficult to treat and manage, making healing of this fracture problematic. EVIDENCE ACQUISITION A search of the entire PubMed (MEDLINE) database using the terms scaphoid fracture management and scaphoid fracture evaluation returned several relevant anatomic and imaging references. RESULTS Wrist fractures...

Scaphoid stress fractures are rare and can be a cause of wrist pain in sportspersons. All the cases reported in the literature have been sportspersons. Missing a scaphoid stress fracture could lead to non-union of the scaphoid and early degenerative arthritis of the radio-carpal joint. This can cause chronic wrist pain and can reduce the career span of a sportsperson. We report a case of non un...

In an earlier study we have proposed a scaphoid decision-protocol in order to improve diagnostic accuracy in case of suspected scaphoid fractures. This pilot study evaluated this protocol. In this pilot study (n = 31) most cases with clinical suspicion of scaphoid fractures reached a positive test result on the combined 7 clinical tests (93.5%). Using this test combination, no scaphoid fracture...

We report up-to-date one-year prospective data on the incidence of scaphoid fracture in skeletally immature patients managed in a Fracture Clinic of a Level I Trauma Centre in a University Hospital in the UK. All scaphoid fractures were immobilised until union was achieved. One hundred twenty one skeletally immature patients were referred for a suspected fracture of the scaphoid. Fourteen patie...

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 ...
