Stability of the sternoclavicular joint. A retrospective study.
Enlargement of the sternoclavicular joint is a well-documented but little recognised complication of radical neck dissection [AJR 3 (1971) 584]. We examined the stability of the sternoclavicular joint in 61 patients who had had radical neck dissection, functional neck dissection or sternomastoid division in the treatment of torticollis. Our findings support the hypothesis that postoperative stability of the sternoclavicular joint depends on the integrity of the accessory nerve and probably the proprioceptive branches of C3 and C4 of the cervical plexus. We conclude that in patients who require surgical section of the sternomastoid muscle in the treatment of torticollis, or for venous access in microvascular reconstruction, enlargement of the sternoclavicular joint should not occur as a postoperative complication, unlike those patients who have radical neck dissection with resection of the accessory nerve.
