Snapping scapholunate subluxation.

Three patients were treated for snapping scapholunate subluxation in four wrists, with disabling pain in three wrists. Conventional roentgenographic techniques were not helpful in diagnosing any of these wrist problems. No complete description of the precise abnormality encountered was found in the surgical or roentgenographic literature. Three of the involved wrists have had surgical correction with good early results.
