Objective: Closed reduction with percutaneous pinning is the treatment of choice for displaced supracondylar humerus fractures in children. In addition to configuration of pin fixation, many factors have been attributed to loss of reduction (LOR). The aim of the present study was to review potential factors that contribute to loss of reduction in the closed management of type III pediatric supracondylar fractures.
Methods: Treatment of 87 patients with type III supracondylar fractures was reviewed to determine factors associated with loss of reduction; 48 patients were treated with lateral pinning and 39 with crossed-pinning after closed reduction. Outcome parameters included radiographic maintenance of postoperative reduction.
Results: Lateral or crossed-pin configuration, pin spread at fracture site, pin-spread ratio (PSR), and direction of coronal displacement of the fracture were not associated with LOR. A significant difference (p = 0.01) was found between LOR rates of patients with medial wall communication and LOR.
Conclusion: Medial wall communication is a contributing factor to LOR in the management of type III supracondylar fractures. Cross-pinning should be preferred when medial wall communication is present, to provide more stable fixation.
