One case of rotational subluxation of the carpal scaphoid.

The authors describe one case of perilunate dislocation. After reduction of the dislocation, there was a residual rotational subluxation of the scaphoid due to dorsal tearing of the scapho-triquetral and radio-scaphoid ligaments. The subluxation results in post-traumatic dorsal instability of the carpus. The authors report their clinical experience and conclude that clinical and radiographic diagnosis is not always easy and treatment, which is always surgical, must aim at joint stabilization and ligament reconstruction.
