Outcome of Supracondylar Fractures of the Humerus in Children Treated by Closed Reduction and Percutaneous Pinning
Supracondylar fractures of humerus in children are common injuries. Displaced fractures areinherently unstable. Conservative treatment results in malunion. Open reduction and internalfixation (ORIF) is more invasive and recovery is prolonged. From September 2004 to September 2005, 102displacedsupracondylarfractures of humerus, agedbetween one andhalf yearto 13 years, weretreated using close reduction and percutaneous Kirschner (K) wire fixation under c-arm fluoroscopy. Seventy nine patients were treated by cross K-wires and in twenty three cases lateral two K-wireswereput.Above elbow plaster ofparis back slab was appliedinall cases for atleastfour weeks.Backslab,K-wireswere removedafterfourweeks andelbowrangeofmotionexercisewas started.Resultswere analyzed using Flynn’s criteria. All patients were followed up to 14th week postoperatively. Incross K-wire group(N=79) 70.8% had excellent, 22.7% good, 3.8% fair and 2.5% had poor results at eight weeks follow up which was improved to 91.1% excellent, 6.3 good, 1.2% fair and 1.26% poor results at 14 weeks follow up. In lateral K-wire group (N=23) 70% had excellent, 21.7% good, 4.3% fair and 4.3% had poor result at eighth week which was improved to 91.3% excellent, 4.3% good, 4.3% fair and no poor result at 14th week follow up. Eight patients got superficial pin tract infection and seven patients sustained ulnar nerve injury post operatively.We recommend this procedure fordisplacedsupracondylarfractures inchildrenas itis safeandcost effectiveprocedurewithacceptablecomplication rates.Key words: closed reduction, humerus, percutaneous pinning, supracondylar fracture
