Advances in elbow arthroscopy.

Arthroscopy of the elbow is a very precise and demanding technique. Because of the proximity of neurovascular structures to the recommended portals, a thorough knowledge of regional and intraarticular anatomy is essential. The high degree of congruency of the articular surfaces and the relatively small capsular volume make sound arthroscopic skills a necessity. With proper precautions, the technique is safe and affords the opportunity to obtain valuable diagnostic information and to perform selected procedures without the morbidity of an arthrotomy.
