Management of Displaced Supracondylar Fractures of the Humerus Using Lateral vs. Crossed K-Wires

This study is currently recruiting participants.
Verified by University of British Columbia, July 2008

Sponsored by: University of British Columbia
Information provided by: University of British Columbia
ClinicalTrials.gov Identifier: NCT00358787
  Purpose

Completely displaced (Type III) supracondylar fractures of the humerus are treated in the operating room and are held together with pins stuck into the bone. There are two ways of inserting the pins: crossed and laterally. The crossed method is often used because it is thought to be more stable, but this method also carries a risk of hitting the ulnar nerve. It is not known which method is more stable. Our hypothesis is that loss of reduction will be equivalent between the two pinning methods.

Arms Assigned Interventions
1: Active Comparator
Supracondylar fracture of the humerus will be reduced and fixed percutaneously with crossed K wires.
Procedure: Crossed K-wiring of supracondylar fracture of the humerus
The fracture will be reduced and fixed percutaneously with crossed K wires.
2: Active Comparator
Supracondylar fracture of the humerus will be reduced and fixed percutaneously with lateral K wires.
Procedure: Lateral K-wiring of supracondylar fracture of the humerus
The fracture will be reduced and fixed percutaneously with lateral K wires.

Detailed Description:

Children with type III supracondylar fractures of humerus who meet the study inclusion criteria will be invited to participate in the study by the on call orthopaedic surgeon. All patients will be required to provide informed consent. Patients will then be randomized through a random number software package and will commence immediately after confirmation of inclusion into the study. The fracture is reduced and fixed percutaneously either with crossed or lateral K wires, according to which group the subject was randomized to. Post reduction antero-posterior and lateral radiographs of the elbow are done in the operating room. Above elbow cast is applied. Radiographs are taken at follow-up visits to the clinic. The radiographs are measured to determine loss of reduction between immediate post-op films and films taken immediately prior to pin removal.
