The Small Finger Reverse Ulnar Digital Artery Hypothenar Palmar Perforator Flap: An Anatomical Study With Clinical Examples.

Background: Local flaps are commonly used for reconstruction of digital soft-tissue defects. There remains a paucity of options available for small finger volar and dorsal soft-tissue defects distal to the proximal interphalangeal joint. The purpose of this study was to analyze perforators along the hypothenar palmar region arising from the artery of the ulnar side of the small finger as it comes off the superficial palmar arch for consistency and potential to be used for perforator-based flap reconstruction of soft-tissue defects and joint coverage of the small finger.

Surgical prevention of terminal neuroma and phantom limb pain: a literature review.

The incidence of extremity amputation is estimated at about 200,000 cases annually. Over 25% of patients suffer from terminal neuroma or phantom limb pain (TNPLP), resulting in pain, inability to wear a prosthetic device, and lost work. Once TNPLP develops, there is no definitive cure.
