Preaxial Duplication in Neonates: Incidence, Classification, and Treatment Options

Preaxial duplication is a rare congenital anomaly affecting 1-2% of neonates, with 10% having upper extremity anomalies. This anomaly, most common in Whites and Asians, typically presents with widening of the tip to two complete thumb rays and may require surgical correction for cosmetic and functional reasons. Treatment options include surgery, preoperative splinting, and different surgical techniques like simple excision or Bilhaut-Cloquet reconstruction. Meticulous physeal rearrangement is crucial for successful excision and reconstruction of the duplicated thumb.
