Surgical treatment of pediatric posttraumatic palmar midcarpal instability: case report.

We treated a 6-year-old child able to extend her wrist only to within 30 degrees of the neutral position secondary to posttraumatic palmar midcarpal instability with palmar and dorsal capsulodesis and pinning. More than 8 years after surgery, she has no complaints referable to her wrist and has 30 degrees of active wrist extension. Although unpredictable in adults, soft-tissue reconstruction is a treatment option in the pediatric patient with posttraumatic palmar midcarpal instability.
