The results of displaced three part fracture of the proximal humerus treated by retro grade nailing +/− cannulated cancellous screws for fixation of the greater tuberosity was analysed.

Displaced three part fractures of the humerus are unstable and difficult to fix. Different methods of operative treatment available for this type of fracture are Kirschner wires, tension band wiring, hemiarthroplasty and open reduction and internal fixation with plate and screws.

The Halder Humeral Nail was introduced through the olecranon fossa into the head of the humerus, to stabilize the neck of humerus fracture. The displaced greater tuberosity was reduced with a minimal stab incision and fixed with cannulated screws. Compared to other open procedures the proximal exposure was minimal.

47 Patients with displaced three part proximal humeral fractures have been surgically treated since January 1995. 22 Were treated with proximal screws and 25 without proximal screw fixation. There were 32 females and 15 males. The average age was 67.68 years.

Early passive movements were encouraged in the shoulder. Pain was relieved in almost all the patients. 41 Fractures united. 3 Patients had a malunion, 2 had humeral head collapse, and 1 developed AVN of the humeral head.

The authors concluded that displaced three part proximal humeral fractures can be treated using the Halder Humeral Nail, and that this is a simple method of treatment which avoids major surgical exposures.
