Iatrogenic 14 cm defect in the ulnar nerve after percutaneous cross-pinning of supracondylar humeral fracture in a child.

We present a case of a 14 cm defect of the ulnar nerve after percutaneous pinning of a supracondylar humeral fracture in a child. This was treated by taking four sural nerve grafts (16 cm long each) from both legs. Five years later the arm was painless but the hand was a little clumsy and sensation in the little finger was reduced.
