The second dorsal metacarpal artery flap from the middle finger is a reconstructive technique that can be used to repair extensive volar defects in a normal-length thumb. However, few reports advocate using it for coverage of volar thumb defects. In this article, an anatomic study of 9 flaps used for resurfacing thumb defects is presented along with the clinical experience of the authors. ⋯ Therapeutic IV.

We aimed to report by light microscopy the normal histology of the A1 pulley, describe the histologic abnormalities of A1 pulleys in trigger digits, and look for possible correlations between these findings and the severity of the disease. ⋯ The histologic abnormalities observed in the A1 pulley of trigger digits are characteristic and not related to inflammation. As the trigger digit worsens, the gliding surface begins to wear and is gradually replaced by a secondary invasive hyperplasia from the outer layer. These abnormalities could be caused by a modification or an increase of the mechanical stresses along the flexor tendons.

Fingertip or pulp resurfacing is a challenging reconstructive problem, as the treatment varies widely. In this study, we report the results of a dorsal island pedicle flap raised from an adjacent finger, including the bilateral dorsal digital nerves, for coverage of extensive soft tissue defect in the fingertip or pulp. ⋯ Therapeutic IV.
