Predislocation syndrome

Jeffrey E McAlister, Christopher F Hyer
Lesser metatarsophalangeal (MTP) joint instability is a common and painful condition that can severely limit activity and recreation. Synovitis and joint effusion may be seen early on with progression of instability to encompass predislocation and eventual complete dislocation of the MTP joint. Various surgical techniques have been described to treat lesser MTP joint instability and associated hammertoe deformities. Many surgeons experience frustration with the surgical outcome of metatarsal osteotomies and flexor transfers commonly used for this condition...

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...

Predislocation syndrome is defined as an either an acute, subacute, or chronic inflammatory process involving the lesser metatarsophalangealjoints. If left untreated, this process can lead to plantarplate and capsular attenuation and metatarsophalangeal joint instability. A retrospective analysis were performed on eight patients who were treated with a flexor tendon transfer for this condition. A subjective analysis and chart review were performed to determine the final outcome of these patients. All patients had a chief complaint of a painful second metatarsophalangeal joint with seven of eight patients having an associated hallux valgus deformity...
