PULSELESS SUPRACONDYLAR FRACTURES OF THE HUMERUS IN CHILDREN

Birmingham Children’s Hospital, Birmingham, England

We compare the management and outcome of two management stratergies for the perfused but pulseless hand following stabilisation of grade III supracondylar fractures in children.

For this study we looked at 15 patients treated in two centres (all treated by the senior author) between 1995 and 2004. The patients were designated to group I if the pulseless hand had been observed or group II if they underwent immediate exploration. Data collected included time to surgery, neurological deficit, time to return of pulse and subsequent symptoms of forearm claudication. All patients were seen at week 1,3 and followed for at least 6 months post surgery. Radiographs were reviewed to determine the adequacy of reduction of the fracture.

The mean age of patient was 3.8 years. Median time to surgery was 6 hours. 6 children had evidence of anterior interosseus nerve palsy. 12 cases were reduced anatomically, 3 had minimal fracture gap. Of the 8 patients in group I (observation) 2 had secondary exploration and one developed claudication symptoms. All had palpable radial pulse at 3 months.6 of the 7 patients in group II (exploration) were seen to have brachial artery tethering, 2 with median nerve entrapment. 5 of them had subsequent return of radial pulse within 24 hours.

Satisfactory radiological reductionof the fracture does-not exclude vessel or nerve entrapment. We would advocate early exploration of the artery if the pulse does not return within 24 hours.
