Abstract
The purpose of this study was to investigate if there is a relationship between the timing of reduction of displaced supracondylar humerus fractures in children and post-operative complications and open reduction rate and to evaluate the usefulness of the definition of early (eight hours or less following injury) and delayed (more than eight hours following injury) treatment used in the literature.
The case notes of children who were treated at our institution for a Gartland grade 2b and 3 supracondylar humerus fracture between July 1995 and June 2002 were reviewed.
We identified 431 patients with a Gartland grade 3 and 141 patients with a Gartland grade 2b fracture. The time from injury to surgery ranged from 2 hours to 13 days. The average time to reduction was 12 hours for grade 3 injuries and 21 hours for grade 2b injuries. None of the patients had an initial closed reduction in the emergency department. 229 patients were treated early with two compartment syndromes, five ulnar nerve, one lateral cutaneous nerve of the forearm, one median nerve - and one radial nerve palsy, one septic arthritis, one pin site infection, six open reductions; one re-manipulation was required for loss of reduction. The delayed group consisted of 343 patients with six ulnar nerve, three median nerve, one radial nerve and one lateral cutaneous nerve of the forearm palsy, three pin site infections, five open reductions; re-manipulation was required in one patient. All nerve palsies recovered post-operatively. The open reduction rate was two percent. The majority of displaced supracondylar humerus fractures in children do not need to be operated on as an emergency. Operation of fractures not associated with a neurovascular compromise within eight hours of the injury does not seem to reduce the rate of significant complications and open reduction rate. In contrary the most severe complication, the development of a compartment syndrome was only seen in the early group. We did not identify an association between complication rateS and a time threshold. Therefore the differentiation between early and delayed treatment used in the literature seems to be arbitrary and not useful.
