First Metatarsal Headphones-Like Lesion: A Case of Unreducible Sesamoid Complex Dislocation

CASE

A 34-year-old woman sustained a direct trauma to the left hallux during a fall. Radiographs showed a dorsal dislocation of the first metatarsophalangeal joint and a wide separation of sesamoid complex. Closed reduction was tried: postreduction radiographs displayed reduction of first metatarsophalangeal joint and a complete sesamoid complex dislocation. The patient was scheduled for surgery. Through a medial approach, open reduction together with plantar structures release and repair were performed. Functional and radiographic outcomes were satisfactory at the last follow-up.

CONCLUSION

In case of a "headphones-like lesion" surgery is required, together with plantar structures repair.

Another Classification of First Metatarsophalangeal Joint Dislocation-Type 3: Review and Case Description of the Plantar Dislocation

Plantar dislocation of the first metatarsophalangeal joint is a possible, albeit rare, injury to the foot. The mechanism has been attributed to a hyperflexion motion, with the hallux situated plantar to the first metatarsal head. In this article, we provide a case example of an open, plantar dislocation of the first metatarsophalangeal and perform a literature review of this rare injury. Based on x-ray analysis of the published cases, the sesamoids may or may not dislocate with the phalanx based off of the local capsuloligamentous anatomy. As a result, a modified Jahss classification (type 3A and type 3B) has been proposed to amend the existing system, adding plantar dislocations of the first metatarsophalangeal without (type 3A) and with (type 3B) sesamoid dislocation.

Dislocation of the First Metatarsophalangeal Joint: A Case Report and Suggested Classification System

Dislocation of the first metatarsophalangeal joint is a relatively rare and still poorly known injury. The current classification includes only the dorsal variety of this lesion; thus, as further cases of other varieties are reported, a larger understanding of this entity is required. We report the case of a young male with dorsal dislocation of the first metatarsophalangeal joint treated by closed reduction. The clinical outcome at the 2-year follow-up point is reported. A review of the published data of the variations of this injury reported to date is included, and a new summarizing classification is suggested.

Isolated plantar dislocation of the 1st metatarsophalangeal joint

Plantar dislocation of the 1st metatarsophalangeal joint is an extremely rare injury. To the best of our knowledge, there are no previous reports in the literature of an isolated dislocation of this type requiring open reduction and surgical repair. In this case report, we describe the clinical and operative findings and discuss in detail our surgical technique for the successful management of this unusual injury.

Traumatic dislocation of the first metatarsophalangeal joint with entrapment of the flexor hallucis longus tendon

A case of traumatic dislocation of the first metatarsophalangeal joint with concomitant fibular sesamoid fracture and thoracic vertebral fracture is presented. The first metatarsophalangeal joint was repaired by means of open reduction with collateral ligament repair. At 12 months following the operation, the patient displayed nonpainful and unrestricted first metatarsophalangeal joint motion.
