Rotation and Displacement Predict Adverse Events in Pediatric Supracondylar Fractures.
The goal of this study was to identify supracondylar fracture patterns that were predictive of adverse events and poor outcomes. The study consisted of a retrospective review of patients admitted for surgical treatment of a supracondylar humerus fracture between June 2008 and August 2010. Preoperative radiographs were assessed based on appearance (simple vs oblique vs comminuted), coronal plane displacement (angulated, posterior, posteromedial vs posterolateral), and rotation (rotation vs no rotation). Logistic regression models were used to examine the relationship between fracture pattern and clinical outcome parameters in 373 patients who were followed for 4 weeks or more postoperatively. Outcome parameters included postoperative complications (infection, delayed healing, pin migration, revision surgery), need for physical or occupational therapy, need for postoperative intravenous narcotics, and preoperative nerve injury. Rotation and coronal displacement patterns of the fracture segments were significantly associated with postoperative complications, postoperative need for physical or occupational therapy as a result of residual stiffness, and nerve injury (P<.05). Compared with posteriorly displaced fractures, posterolaterally displaced fractures were associated with significantly greater odds of complications (P=.045), need for physical or occupational therapy (P<.001), and nerve injury (P<.001). Additionally, fractures with rotation were associated with significantly greater odds of complications (P<.001), need for physical or occupational therapy (P<.001), and nerve injury (P<.001) compared with fractures without rotation. Rotation and coronal plane displacement were predictive of complications, need for physical or occupational therapy, and nerve injury, and thus should be considered as potential prognostic variables when evaluating the initial injury pattern.
