Reliability of focal identification of motor fascicles of the ulnar nerve proximal to the wrist: an anatomical study.

We investigated whether motor fascicles of the ulnar nerve can be reliably identified proximal to the wrist. In 17 cadaveric upper limbs, the anterior interosseous nerve was transected at its arborization in the pronator quadratus and transposed to the palmar aspect of the ulnar nerve. The motor fascicular bundle was identified at this level after distinguishing the intraneural epineural involution by microsurgical probing.

Nail Bed Reconstruction Using Single-Layer Bovine Acellular Dermal Matrix.

Traumatic nail bed injuries to the hand are a common problem for hand surgeons. Whereas the majority of those are treated with primary repair, the remainder present significant surgical challenges to address residual soft tissue defects. In this article, we present our approach to treating injuries to the fingertips utilizing single-layer bovine acellular dermal matrix grafts.
