Moberg Osteotomy for Hallux Rigidus.

Abstract

Hallux rigidus is a common cause of pain and decreased range of motion of the first metatarsophalangeal joint, notably with loss of dorsiflexion. Hallux rigidus is the second most common disorder affecting the great toe. The primary cause of hallux rigidus is thought to be a traumatic event, a culmination of microtrauma, or an alteration in kinematics leading to a loss of articular cartilage and dorsal osteophyte formation. Surgical treatments include Moberg osteotomy, also referred to as a proximal phalanx extension osteotomy. This article discusses current techniques, developments, complications, outcomes, and management of the Moberg osteotomy.
