Rudimentary polydactyly: report of five cases
The Journal of Hand Surgery
|May 1, 1985
Summary
Rudimentary polydactyly, a rare condition, may be an amputation stump of pedunculated fingers. Surgical exploration revealed a unique cord-like structure connecting to the digit's neurovascular bundle.
Area of Science:
- Hand surgery
- Congenital anomalies
- Developmental biology
Background:
- Rudimentary polydactyly is a rare congenital anomaly.
- Previous surgical findings in these cases have not been published.
Observation:
- Surgical exploration of rudimentary polydactyly papules revealed novel findings.
- A distinct cord-like structure was observed originating from the papule's base.
Findings:
- The cord-like structure's proximal portion connected to the digit's neurovascular bundle.
- Histologic examination indicated the cord closely resembles a finger's neurovascular bundle.
Implications:
- This suggests rudimentary polydactyly might represent an amputation stump of pedunculated fingers.
- Further research into the developmental origins of polydactyly is warranted.
