DISPLACED SUPRACONDYLAR FRACTURES OF THE HUMERUS IN CHILDREN

We studied the outcome of displaced supracondylar fractures in 98 children treated over three years to December 2000. In 74 patients fractures were treated by closed reduction and percutaneous K-wire fixation. Through a direct posterior approach, open reduction was obtained in the other 24. Postoperatively the elbow was immobilised in a posterior cast in 30° flexion for three to four weeks. The cast and K-wires were removed in the clinic and the elbow mobilised. In patients treated by closed reduction, the mean range of movement (ROM) was 10° to 120° at the one-month follow-up. There was a cubitus varus deformity in four patients. One patient developed pintract infection. There were five neurological complications, of which only one (ulnar nerve) was surgical. The mean ROM of patients treated by open reduction was 15° to 110° at the one-month follow-up. Pre-operatively two patients in this group had a neurological deficit (one median and one radial nerve), which had improved at follow-up. Treatment of supracondylar humeral fractures in children by closed reduction and percutaneous K-wires is safe and reliable. Where open reduction is necessary, a posterior approach is more acceptable cosmetically and does not lead to functional loss.
