Mid-term Patient-reported Outcomes After Lateral Versus Crossed Pinning of Pediatric Supracondylar Humerus Fractures

Background: Closed reduction and percutaneous pinning in a crossed or lateral configuration is the standard treatment for supracondylar humerus (SCH) fractures. We compared mid-term patient-reported outcomes (PROs), radiographic outcomes, and complication rates between patients treated with crossed versus lateral pinning. Methods: We reviewed 508 pediatric patients treated surgically for Gartland type-III SCH fractures from 2008 to 2017. We included patients aged 5 to 17 years at the time of telephone interviews, who had available radiographs. We excluded those unable to be reached by telephone; those who declined to be surveyed; and those lost to follow-up. Our sample comprised 142 participants (28%) (mean +/- SD age at surgery, 5.2 +/- 2.0 y), 93 (65%) of whom were treated with lateral pinning and 49 (35%) with crossed pinning. Participants' parents completed the Quick Disabilities of the Arm, Shoulder, and Hand and the Patient-Reported Outcomes Measurement Information System Parent Proxy at a mean 4.4 years (range: 2 to 10 y) postoperatively. Postoperative radiographs were reviewed to assess reduction. Bivariate analysis was performed to determine whether outcomes differed by pinning technique (alpha=0.05). Results: The proportions of participants achieving complete reduction were not significantly different between pin configuration groups (P=0.71). At follow-up, the 2 groups did not differ significantly in any PRO scores (all,P>0.05). Conclusion: We found no differences between crossed and lateral pinning of Gartland type-III SCH fractures in terms of radiographic reduction, PROs, or complication rates at mid-term follow-up.
