Surgical treatment of comminuted, displaced fractures of the greater tuberosity of the proximal humerus: a new technique of double-row suture-anchor fixation and long-term results.

Conventional techniques of internal fixation of displaced fractures of the greater tuberosity may be insufficient in presence of comminution. A new surgical technique of internal fixation using a double-row of suture-anchors is described. Long-term results of this technique are evaluated in 21 patients with an isolated, displaced and comminuted greater tuberosity fracture at an average of 3.5 years (range 1-5 years) after surgery. The average age of the patients in the study was 51 years (range 17-93 years). Twenty fractures healed without post-operative displacement. The result was rated as excellent in 8, good in 10, satisfactory in 2 and unsatisfactory in 1 patient. Post-operative bicipital impingement in two patients and reaction to fixation material in one patient resulted in persistent, severe pain in the rehabilitation period, necessitating additional surgery.
