title: Predislocation syndrome: a review and retrospective analysis of eight patients.
abstract: 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. Excellent results were achieved in six patients. Residual stiffness was the primary complaint of two patients following surgery, suggesting that metatarsophalangeal joint stiffness may be a potential problem after flexor digitorum longus tendon transfers. However, we concluded that the flexor digitorum longus tendon transfer remains an excellent procedure for second toe instability and late-stage predislocation syndrome. A literature review describing the epidemiology, symptom complex, physical findings, radiographic signs and therapies used to manage predislocation syndrome were also discussed.
