Abstract
Introduction: Traumatic and iatropathic nerve injuries complicate 6–16% of paediatric supracondylar extension fractures of the humerus. The majority recover spontaneously. This retrospective review of lesions referred to our tertiary unit determined the incidence of surgical intervention.
Methods: Between 1997–2002, 37 neuropathies (32 fractures) in 19 males and 13 females (mean age 7.9yrs) were referred for further management. 8 fractures were Gartland grade 2 and 24 grade 3. All fractures were closed. Two were originally treated non-operatively, 20 by closed reduction and percutaneous pinning and 10 by open reduction and internal fixation.
Results: The ulnar nerve was most frequently injured (19, 51.4%), followed by median (10, 27%) and radial (8, 21.6%) nerve palsies. 14 (37.8%) neuropathies were fracture-related but 23 (62.2%) were treatment-related. 10 patients (31.3%) required operative exploration. Three (9.4%) were listed for surgery but cancelled due to nerve recovery. Nerve grafting using either the forearm medial cutaneous nerve or the superficial radial nerve was necessary in 4 of 10 operated cases. 26 patients (81.3%) had excellent outcomes, 5 (15.6%) good and 1 (3.1%) fair.
Discussion: In contrast to current literature suggesting that 86 to 100% of supracondylar associated neuropathies recover spontaneously within 2 to 3 months, surgical exploration was required in over 30% of cases.
