Anterior superior dislocation of the hip joint: a report of 3 cases and review of the literature

Abstract

Traumatic anterior dislocation of the hip forms approximately 11% of hip dislocations and is divided into superior and inferior types. Anterior superior hip dislocation accounts for 10% of anterior hip dislocations. The clinical appearance of anterior superior hip dislocation resembles that of a fracture of the femoral neck, whereas the radiological appearance resembles that of posterior hip dislocation. The objective of this article is to use three cases to describe the management of this condition and highlight pitfalls in the same. The article also points out unusual mechanisms causing this injury.
