Primary bone healing fails to occur in 5-15 % of scaphoid bones that undergo fracture fixation. Untreated, occult fractures result in nonunion up to 12 % of the time. Conventional bone grafting is the accepted management in the treatment algorithm of scaphoid nonunion if the proximal pole is vascularized. Osteonecrosis of the proximal scaphoid pole intuitively suggests a need for transfer of th...
We describe a percutaneous technique for screw fixation of all types of fractures of the scaphoid. During a 15-year period ending in 1984, 280 cases were treated by this method; 198 of them returned for evaluation in 1986 and comprise the material for this report. After a mean postoperative time of 82 months, 89% of the recent fractures had united as well as 81.8% of those with delayed or nonun...
BACKGROUND A scaphoid fracture is the most common type of carpal fracture affecting young active people. The optimal management of this fracture is uncertain. When treated with a cast, 88 to 90 % of these fractures unite; however, for the remaining 10-12 % the non-union almost invariably leads to arthritis. The alternative is surgery to fix the scaphoid with a screw at the outset. METHODS/DES...
UNLABELLED To assess the cost-effectiveness of various strategies for the diagnostic management of clinically suspected scaphoid fracture, a decision-analytic model was built to evaluate three strategies and to compare them with a (clairvoyant) reference diagnostic management strategy. METHODS Evaluated strategies were: (A) repeated radiography up to 2 wk; (B) repeat radiography up to 6 wk; a...
We present the case of an 18-year-old high-level gymnast who sustained a stress fracture of the scaphoid associated with a distal radial epiphysiolysis. Clinical evaluation demonstrated decreased range of motion of the affected wrist and insidious pain on the snuffbox and tenderness on the distal radial physis. He was submitted to surgical treatment with scaphoid percutaneous fixation and radia...
In addition to the benefit of open surgical treatment of the scaphoid, a reduced downtime and a rapid return to work, percutaneous screw technique also reduces operative risks, avoids the possibility of soft tissue collapsing, the devascularisation of the fracture site and therefore is associated with lower risks of nonunion. The authors report the case of a 27-year-old patient, receiving surgi...
Background: Fractures of the scaphoid are second most common fractures upper limb after distal radius fractures. Rapid and accurate diagnosis is needed, because delayed initiation therapy increases risk complications such as non-union avascular necrosis. Objectives: To compare between diagnostic accuracies Computed Tomography Magnetic Resonance Imaging in detecting its complications. Methods: T...
