Neurovascular injury from supracondylar fractures in children: a 10-year experience of 762 cases

Abstract

We evaluated the management of supracondylar paediatric fractures at our institution over a 10-year period in this retrospective cohort study. In total, 762 children with a supracondylar fracture were treated. The mean age of injury was 5.2 years. The incidence of documented nerve and/or vascular injury was 8.3%. A total of 26 patients had early plastic surgeon involvement; of these, 25 had an open exploration. Eight patients required vein grafting for brachial artery reconstruction for intimal tears. There was one nerve rupture requiring repair and 12 children underwent neurolysis. There were 17 late referrals to the plastic surgery service, of which three were explored (two neurolysis, one neuroma resection and sural nerve grafting). In all cases of nerve injury, the deficit took 7.9 months to recover, indicating a more significant injury than neurapraxia. Early exploration of supracondylar fractures allows direct visualization of the extent of neurovascular injury and immediate intervention. Level of evidence: IV
