Minimizing risk to the dorsal sensory branch of the ulnar nerve in wrist arthroscopy: an anatomical study.

Wrist arthroscopic procedures using ulnar wrist portals, such as the 6-ulnar and direct foveal portals, have a risk of injuring the dorsal sensory branch of the ulnar nerve. This study investigated the anatomy of the dorsal sensory branch of the ulnar nerve and its positional changes during supination, neutral rotation and pronation at specific landmarks to find an optimal forearm position to minimize the risk of iatrogenic nerve injury during arthroscopy. The concept of 'nerve density' was introduced to quantify the likelihood of encountering the dorsal sensory branch of the ulnar nerve within different sectors, correlating to the risk of nerve injury.

Preservation of terminal branches of the palmar cutaneous branch of the median nerve in open carpal tunnel release.

Purpose: Post-operative pain in the palm and scar area is the most common complication after carpal tunnel release and injury to the terminal branches of the palmar cutaneous nerve is generally considered one of the causes for this complication. The Authors performed an intraoperative study preserving the terminal branches of the palmar cutaneous branch of the median nerve and verifying the frequency, location and direction of the branches that cross an interthenar incision.

Method And Material: Eighty-five consecutive patients (57 F - 28 M, mean age 66 y) underwent carpal tunnel release between February and June 2021.

Wrist Arthrolysis: A Systematic Review of Open and Arthroscopic Techniques.

 Wrist arthrolysis is a viable option in wrist stiffness and can be performed via open or arthroscopic techniques.  The aim of the study is to describe and evaluate the available techniques of open and arthroscopic arthrolysis of the radiocarpal joint and the distal radio ulnar joint (DRUJ) in posttraumatic wrist stiffness.  A systematic literature search was performed in PubMed to identify studies reporting on open and arthroscopic wrist arthrolysis.
