Fig. 3From: Arthroscopically-assisted reduction and pinning of a radial neck fracture in a child: a case report and review of the literature(a, b) Arthroscopic images before fracture reduction. Notice the abnormal distance (white arrow) between the radial head (A) and the capitulum humeri (B), which should normally be in contact. The condropick arthroscopic instrument easily passes through the articular space over the annular ligament (C) between the capitulum humeri and the radial head; this is an indirect sign of articular incongruityBack to article page
