DO DISPLACED SUPRACONDYLAR FRACTURES HAVE TO BE REDUCED IN THE MIDDLE OF THE NIGHT?

Abstract

All supracondylar humeral fractures managed with closed or open reduction and pin fixation at the Hospital for Sick Children between 1995 and 2002 were retrospectively reviewed. Time from injury to treatment, post reduction complications and need for open reduction were recorded. Fractures treated ≥ 8 hours from injury were considered in the early treatment group while > 8 hours were considered in the late treatment group. Fractures presenting with a cold hand (four patients) were taken to the operating room as quickly as possible and were excluded from the study.

There were 431 patients with a Gartland grade 3 and 141 patients with a Gartland grade 2b. 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. The early treatment group consisted of 230 patients with two compartment syndromes, six ulnar-, one superficial radial-, one median- and one radial nerve palsy, one septic arthritis, one pin site infection, six open reductions and one re-manipulation was required for loss of reduction. The late treatment group consisted of 342 patients with six ulnar-, three median-, one radial nerve palsy and one lateral cutaneous nerve of the forearm palsy, three pin site infections, five open reductions and re-manipulation was required in one patient. All nerve palsies recovered post-operatively.

Conclusion: There was no significant difference in the proportion of complications between the early and late treatment group, but the most severe complication, the development of a compartment syndrome was only seen in the early group. Delayed treatment of supracondylar humeral fractures seems to be safe in a large number of patients, and in fact, most of our patients were treated more than eight hours from the injury. Early operation of fractures not associated with a neurovascular compromise also does not seem to reduce the complication rate. Nevertheless the decision when to operate needs to be decided for each patient individually.
