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

Metacarpophalangeal dislocations of the index finger are rare in the pediatric population.

In such cases, surgeons may prefer a dorsal or volar approach to open and reduce the joint. Unsuccessful open reduction is rare.
