Reduction and K-wiring is the most popular form of treating displaced supracondylar fractures of the humerus. Complications including redisplacement of the fracture, cubitus varus, iatrogenic nerve injuries and pin tract infection have been reported following surgery. For successful outcome with K-wiring of supracondylar fractures, strict adherence to protocols and surgical expertise are necessary. We have treated these fractures in straight arm traction since 1995, and the purpose of this study was to audit our practice.

Between January 1995 and December 2000, 112 children with a closed displaced supracondylar fracture of the humerus, without neurovascular deficit, were managed by straight arm traction for a mean duration of 22 days. Final outcome was assessed using clinical (flex-ion-extension arc, carrying angle and residual rotational deformity) and radiographical (metaphyseal-diaphyseal angle and Humero-Capitellar angle) criteria. Our outcomes were compared with those of the recent large studies reporting results of surgical treatment.

71 (63%) patients had excellent, 33 (29%) patients good, 5 (4.4%) patients fair, and 3 (2.6%) patients poor outcome. All patients with fair or poor outcomes were older than 10 years.

Elevated straight-arm traction is safe and effective in children younger than 10 years. It can be effectively used in an environment that has provision of paediatric medical care and general orthopaedic expertise with outcomes comparable to those fractures treated surgically in specialist centres.

The final outcome was assessed using clinical (flexion-extension arc, carrying angle and residual rotational deformity) and radiographic (metaphyseal-diaphyseal angle and humerocapitellar angle) criteria. Excellent results were achieved in 71 (63%) patients, 33 (29%) had good results, 5 (4.4%) fair, and 3 (2.6%) poor. All patients with fair or poor outcomes were older than ten years of age.

Elevated, straight-arm traction is safe and effective in children younger than ten years. It can be effectively used in an environment that can provide ordinary paediatric medical care and general orthopaedic expertise. The outcomes compare with supracondylar fractures treated surgically in specialist centres.
