Abstract
Humeral shaft fractures represent 3% of all fractures, there is significant number of these fractures require operative intervention.
Current indications for operative fixation include high energy fracture pattern (comminuted, segmental), floating elbow injuries, bilateral fractures, open fractures, vascular injury or progressive neurologic injury, and multiply traumatized patients.
Interlocking nails have been developed for the humerus after the wide spread enthusiasm for the tibial and femoral nails. These nails are biological means of fixation and mechanically stable, providing the optimum environment for facture healing.
The A-H nail was used in this work in the treatment of 30 patients with humeral shaft fractures. They were 20 males and 10 females. The right side was fractured in 17 cases and the left side in 13 patients.
22 patients had closed fractures of the humeral shaft and 2 patients had open fracture
(1st degree). The commonest mechanism of injury was falling either on out stretched hand or direct fall on the arm 18 cases (60%), the next common mechanism of injury was the road traffic accident 9 cases (30%), 1 case was due to machine traction injury (3%), and 2 cases due to pathological cases (7%).
Nailing was done after an average was 7,4 days from the injury. Patients were followed up for union, and clinical assessment was done using a numerical scoring system including, Shoulder scoring system of Constant and Murielle, and Brumback criteria for the elbow.
The final function out come was excellent in 26 (86.7%) patients, satisfactory in 2 patients (6, 7%) and unsatisfactory in 2 patients (6, 7%).
