Key Points: Acute CRPP can successfully restore CMC joint congruity and function in first-time, traumatic, reducible but unstable CMC joint dislocations in pediatric patients.

Thumb carpometacarpal (CMC) joint dislocations make up approximately 1% of acute hand injuries. The most common variant is the Bennett fracture, which is a fracture-dislocation at the thumb CMC joint.

Figure 2. Postoperative x-rays of right hand: anteroposterior, oblique, and lateral views demonstrated anatomic reduction of the carpometacarpal dislocations.
