Analysis of radiographs of 52 wrists showed that, from ulnar to radial deviation, the amount of scaphoid shortening and ulnar translation of the scaphoid varies in a normal distribution. There is a significant correlation between the two measurements, such that the more the scaphoid shortens the less it translates and vice versa. Females subjects were more likely to have greater scaphoid shorte...

Nondisplaced fractures of the scaphoid heal with cast immobilization in most cases, but operative treatment is being offered with greater frequency to active patients as an approach to reduce the period of cast immobilization. Computed tomography is more useful for evaluating displacement than standard radiography. Displaced fractures are at greater risk for nonunion and malunion-both of which ...

We report on a case of aplasia or unilateral congenital absence of the carpal scaphoid associated with dysplasia of the capitate. Congenital absence of the carpal scaphoid is a rare but well-documented condition. As far as we know, the present case is the seventh one reported in the medical literature. Imaging studies (X-ray and MRI) confirmed the absence of the carpal scaphoid associated with ...

Traumatic lipohemarthrosis of the wrist joint in association with a scaphoid fracture is an unreported entity. We present the first case report of MRI appearance of a double fluid-fluid level of lipohemarthrosis caused by a scaphoid fracture. The presence of a double fluid-fluid level within the injured joint definitely establishes a lipohemarthrosis. A traumatic lipohemarthrosis is considered ...

This study correlated morphologic abnormalities of idiopathic carpal tunnel syndrome (CTS) with the severity of CTS using 3-T magnetic resonance imaging (MRI). The relationship of the severity of CTS and the cross-sectional area of the median nerve (CSA) was assessed at several levels. Seventy wrists of 35 patients (27 women and 8 men) with unilateral idiopathic CTS underwent nerve conduction s...

The scaphoid is vitally important for the proper mechanics of wrist function. Fracture of the scaphoid bone is the most common carpal fracture. Among all wrist injuries the incidence of scaphoid fracture is second only to fractures of the distal radius. Scaphoid fractures are significant because a delay in diagnosis can lead to a variety of adverse outcomes that include nonunion, delayed union,...

Introduction/Methods: Scaphoid fractures are the most common fractures of the carpal bones of the wrist, and represent 11% of all fractures of the upper extremity and between 70% and 80% of all carpal fractures. In most cases, the mechanism of injury is a fall with the wrist extended. Although conservative treatment of stable fractures of the carpal scaphoid associated with a high rate of conso...

A rare injury of the wrist, scapho-capitate fracture syndrome, in a young patient is reported. Despite early recognition of the injury and surgical intervention, the scaphoid fracture did not unite and another attempt to achieve union with bone grafting and internal fixation also failed. The wrist continued to be painful and stiff. Radiographs of the wrist, 18 months after the injury, showed no...

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...

Nonunion can occur relatively frequently after scaphoid fracture and appears to be associated with severity of injury. There have been a number of techniques described for bone grafting with or without screw fixation to facilitate fracture healing. However, even with operative fixation of scaphoid fractures with bone grafting nonunion or malunion rates of 5 to 10 percent are still reported. Thi...
