Little Finger Flexor Tendoscopy, Endoscopy of the Ulnar Bursa and Midpalmar Space.

Inflammatory, infectious, and even neoplastic processes can involve the deep subfascial space of the hand. Suppurative deep-space infection is treated primarily with surgical drainage. Open approaches to these deep spaces carry the risk of exposed flexor tendons and nerves without adequate soft tissue coverage. The purpose of this Technical Note is to describe the technical details of little finger flexor tendoscopy, endoscopy of the ulnar bursa and midpalmar space, which will reduce the risk of exposed tendons or nerves associated with open approaches and allow aggressive hand therapy in the early postoperative period because of the minimal surgical trauma and small surgical wounds.
