Complex Dislocation of the Metacarpophalangeal Joint in the Index Finger of a Child: A Case Report.

Methods: The author reports a complex metacarpophalangeal joint dislocation in a 14-year-old adolescent boy with multiple failed closed reduction manipulations and unsuccessful open procedures. The patient underwent another surgical procedure through the same volar approach, and the joint was reduced along with the volar plate repair. The functional outcome at 1-year follow-up was excellent.

Conclusions: Metacarpophalangeal dislocations of the index finger are rare in the pediatric population. The interposition of the volar plate is the significant barrier to reduction and the prime reason for unsuccessful closed reduction attempts. In such cases, surgeons may prefer a dorsal or volar approach to open and reduce the joint. Unsuccessful open reduction is rare.
