Complex interphalangeal dislocation of the fourth toe after a sports injury: case report

Traumatic boutonniere deformity of the second toe caused by sumo wrestling: A case report

•

A case of boutonniere deformity of the second toe caused by sumo wrestling.

•

Forced passive flexion exerted on an actively extended PIP joint is the likely cause.

•

Surgical repair of the extensor mechanism and temporary pinning were effective.

Introduction

Traumatic boutonniere deformities of the fingers are well documented unlike those of the lesser toes. With few existing reports on boutonniere deformities of the lesser toes, the related pathology and treatment guidelines remain unclear.

Presentation of case

We present a case of traumatic boutonniere deformity of the second toe caused by sumo wrestling in a 23-year-old man. A flexion deformity of the proximal interphalangeal joint and hyperextension of the distal interphalangeal joint of the right second toe were observed, including a torn central slip and plantarly displaced lateral bands during surgery. Surgical repair of the extensor mechanism and temporary pinning led to good clinical results.

Discussion

Acute traumatic boutonniere deformity of the interphalangeal joint of the lesser toe is very rare. The mechanism of boutonniere deformity in this case is thought to be due to forced passive flexion exerted on an actively extended PIP joint, which is similar to that seen in fingers.

Conclusion

We describe the pathophysiology of a case of boutonniere deformity of the lesser toe and suggest the effectiveness of surgical treatment.

Multiple Open Dislocations of the Lesser Interphalangeal JointsA Case Report

We report on the rare case of multiple open interphalangeal dislocations. This uncommon pathologic condition results from dorsiflexion and axial loading of the digit. In the present patient, closed reduction was not possible. We review the literature on this pathologic condition and present a case of open irreducible dislocation of the lesser interphalangeal joints complicated by peripheral neuropathy and treated with resectional arthroplasty.

Management of nonreducible lesser toe interphalangeal dislocation: an unusual injury

Interphalangeal joint dislocations of the lesser toes are relatively rare in clinical practice. Most nonreducible interphalangeal joint dislocations occur as a result of rupture or interposition of the plantar plate or of the collateral ligament in the joint space, thus hindering a closed reduction and, in most cases, compelling an open reduction. A post-reduction radiologic exploration is then essential to identify such an entity and proceed consequently. In some cases, such as the one introduced herein, a misdiagnosis, along with an inadequate surgical correction may lead to recurrence of the deformity and, ultimately, to a salvage arthrodesis.

Boutonniere deformity of the second toe after planter dislocation of proximal interphalangeal joint: a case report

The boutonniere deformity is a well-known deformity in the fingers, however, its appearance on a lessor toe is extremely rare. In the present case, the deformity resulted from a rupture of the central slip of the extensor tendon and the shift of the lateral bands to the planter side after reduction of a traumatic planter dislocation of the PIP joint of the second toe. Surgical repair of the extensor mechanism brought good results.
