Abstract


Avascular necrosis or osteonecrosis is said to be higher when the fracture involves proximal one-third of the scaphoid with an incidence of 13 % to 27%1. The reason for this is the tenuous1 blood supply of the scaphoid, primarily from the branch of the radial artery entering mainly from the distal and dorsal surface of the bone. The proximal pole, therefore, is dependent entirely on this intraosseous blood flow. This retrograde, axial and unidirectional pattern of blood supply can result in a protracted healing process after a fracture which eventually leads to osteonecrosis, collapse and arthritis leading to disability.

Abstract

Combined fracture neck femur with anterior dislocation of the head of femur is a very rare and with little resources available in the literature. We hereby report a case condition treated by unipolar arthroplasty with Austin Moore prosthesis with 6-month follow-up showing good radiological and functional outcome. Functional evaluation at the end of follow-up was assessed according to Merle d’Aubigné score modified by Matta JM, which takes into account of the presence of pain, ability to walk, and joint range of motion. The measured functional score was 15 points out of a maximum of 18, signifying a good post-operative result.
Keywords: Anterior hip dislocation, Avascular necrosis.
