Mirror hand and its management: a case report

Mirror hand is a rare congenital anomaly. Most of these cases are sporadic and associated with defective sonic hedgehog during embryogenesis. In this report, we present the case of a child with this rare congenital anomaly and its management.

A 2.5-year-old Asian female child presented with left-sided Al Qattan type 1A ulnar dimelia with restriction of wrist and elbow range of motion. Radiological examination revealed duplication of ulna with polydactyly. Management of mirror hand is a great surgical challenge, so preoperative planning and staged management is essential for the functional outcome of this condition. We successfully achieved fine and gross motor skills of the hand with acceptable cosmetic results at 2 years of follow-up.

It is crucial to remember that early intervention, ideally between 18 and 24 months of age, is key for optimal functional outcomes. Meticulous preoperative planning and surgical technique are essential. Long-term follow-up and parental counseling about the need for supervised physical therapy are important for managing secondary deformities. Additionally, digital subtraction angiography should be performed to rule out any associated neurovascular malformations.
