Arthroscopy of the elbow.

Arthroscopy of the elbow is a technically demanding surgical procedure and attention to detail is essential. The surgeon needs a thorough knowledge of the extraarticular portal anatomy to avoid damaging nearby neurovascular structures. Several technical points need to be considered at all times, especially maintaining the elbow at 90 degrees of flexion to relax the neurovascular structures and maximally distended to move them farther away from the entering arthroscopic instruments.
