Predislocation syndrome. Progressive subluxation/dislocation of the lesser metatarsophalangeal joint.
Progressive subluxation/dislocation of the lesser toes resulting from idiopathic inflammation about one or more of the lesser metatarsophalangeal joints is a common cause of metatarsalgia that is frequently unrecognized or misdiagnosed. The disorder results from a failure of the plantar plate and collateral ligaments that stabilize the metatarsophalangeal joints and is typically associated with abnormal forefoot loading patterns. The authors refer to this condition as predislocation syndrome and have devised a clinical staging system that is based on the clinical signs and symptoms present during examination. A thorough review of predislocation syndrome and an overview of the conservative and surgical treatment options available for this disorder are presented.
