Treatment of scaphoid fractures and nonunions.
Scaphoid fractures are common but present unique challenges because of the particular geometry of the fractures and the tenuous vascular pattern of the scaphoid. Delays in diagnosis and inadequate treatment for acute scaphoid fractures can lead to nonunions and subsequent degenerative wrist arthritis. Improvements in diagnosis, surgical treatment, and implant materials have encouraged a trend t...
متن کاملComparison of Fixation Methods for Scaphoid Nonunions
The purpose of this study was to analyze the relative biomechanical stability of three types of internal fixation with cancellous bone graft in a cadaveric, scaphoid nonunion model. A scaphoid nonunion model was created by removing a volar wedge of bone from the waist of the scaphoid in 18 fresh frozen human cadavers. Cancellous sawbone graft was inserted into the osteotomy site and three group...
متن کاملScaphoid fractures and nonunions: diagnosis and treatment
BACKGROUND Scaphoid fractures are commonly seen in orthopedic practice. An organized and thoughtful approach to diagnosis and treatment can facilitate good outcomes. However, despite optimal treatment, complications may ensue. In the setting of nonunion or an avascular proximal pole, vascularized bone grafting may be needed. METHODS AND RESULTS In this article we review the literature regardi...
متن کاملFractures and nonunions of the carpal scaphoid in children.
Fractures of the carpal scaphoid in children show some quite remarkable differences with respect to fractures of the carpal scaphoid in adults. A review of the literature shows that fractures in children are more often located in the distal third, are more often incomplete and are usually not displaced. Our experience with 23 fresh fractures of the carpal scaphoid in children confirms these fin...
متن کاملCongenital hypoplasia of the carpal scaphoid bone.
Three cases of absence of the carpal scaphoid bone have previously been reported in this country (Hodgson 1943, Hanley and Conlon 1957). All three had similar deformities, namely absence or hypoplasia of the carpal scaphoid bone, associated with retardation in the development of the first metacarpal bone, the styloid process of the radius and thenar muscles. While agreeing with these authors th...
