FRACTURES OF THE HUMERUS IN CHILDREN USING PERCUTANEOUS PINNING OR OLECRANON SCREW TRACTION.

Abstract

Introduction: To compare olecranon screw traction with percutaneous pinning for the treatment of Gartland III supracondylar fractures in children.

Methods: This was a retrospective study of 151 patients between 1986 and 1996 treated with olecranon screw traction and 92 patients between 1996 and 2002 treated with percutaneous pinning. Both sets of patients were followed up clinically and radiologically following their injuries until there was evidence of fracture union and the child could demonstrate a satisfactory range of movement. Data recorded included demographics, fracture information, neurovascular injury, operation details, length of stay, length of follow up and clinical outcome. Radiographs were used to measure initial and final Baumann angles to give an indication of outcomes of distal humerus alignment.

Results: Results are shown for the percutaneous pinning group with the olecranon screw traction results in brackets for comparison.

The percutaneous pinning study included 54 (88) males and 38 (63) females with 63% (63%) left and 37% (37%) right elbow fractures. 46% (29%) of fractures occurred at home, 46% (56%) sustained the injury whilst playing and 7% (7%) occurred at school/nursery. The mean age was 6.0 (6.8) years with a range of 21–165 (12–168) months. The radial pulse was absent in 12% (13%). None of the fractures were open (compared with 5%). There were neurological deficits in 20% (17%). The median time to surgery was 5 hours. The fracture needed to be opened in 12% of cases as satisfactory reduction could not be achieved closed. The median stay length was 1 day (compared to a median stay on traction of 14 days). Mean follow up was 15.2 weeks. (Compared to 38.0 weeks). 2 % (3%) had cubitus varus detectable clinically. Median time to recovery for neurological deficit was 24 weeks (18 weeks). Mean initial Baumann’s angle was 74.6 degrees (73.7degrees). Mean final Baumann’s angle was 75.3 degrees (76.0 degrees)

Discussion: Outcomes achieved from percutaneous pinning of displaced supracondylar fractures are similar to those from olecranon screw traction. The advantage of percutaneous pinning to both patient and provider is the reduced hospital stay and duration of follow up. Olecranon screw traction remains a possible treatment option for the management of this injury.
