An Unusual Variety of Scapho-Capitate Syndrome

Abstract

We report a patient who sustained a displaced fracture of the lunate in association with fractures of the scaphoid and capitate. Union of the scaphoid and capitate fractures followed fixation with Herbert screws, 25 additional cases from the literature have been reviewed.

Differential diagnosis of a fused wrist with a partially destroyed capitate from Kazakhstan (1st–3rd century AD)

“…The malposition of the capitate head commonly leads to avascular necrosis and pseudarthrosis (Green and O'Brien, 1980;Minami et al, 1987;Yoshihara et al, 2002) due to its peculiar blood supply making it prone to necrosis (Colonna et al, 2013;Vander Grend et al, 1984). The injury is typical for young men, who are involved in high-energy trauma or falling from height (Milliez et al, 1993;Saffar, 1990). The most common mechanism is a fall on the hyperextended wrist (Monahan and Galasko, 1972;Shaikh and Saeed, 2007).…”

A Unique Presentation of Scaphocapitate Syndrome With Extrusion Into the Carpal Tunnel: A Case Report

“…2,12 There is a general consensus among authors that injuries of this variety require open anatomic reduction of both the capitate and scaphoid, followed by internal fixation. 2,5,7,[11][12][13] Although the proximal portions of both the capitate and scaphoid are vulnerable to posttraumatic avascular necrosis due to the retrograde blood supply of these fragments, the capitate head is nourished by synovial fluid and has demonstrated the ability to revascularize when anatomically reduced. 14 Excision of the proximal capitate fragment will lead to a predictable progression of degenerative arthritis 6 ; thus, regardless of the injury pattern, salvage of this fragment should always be attempted.…”

Scaphocapitate Syndrome With Associated Trans-Scaphoid, Trans-Hamate Perilunate Dislocation

“…6,15 Lack of clinical suspicion due to rarity of the injury and poor initial radiographs may cause the condition to be undiagnosed at initial presentation. 7,9,12,14 Delayed diagnosis of this condition has been reported in up to 25% of cases. 4 For this reason, we advocate the use of CT to help diagnose and further characterize the pattern of injury.…”
