Background:
The impact of humeral rodding on functional ability in children with osteogenesis imperfecta (OI) has not previously been reported. This article investigates this issue.
Methods:
A retrospective chart review was conducted on 35 children with OI who underwent humeral rodding at our institution between 1995 and 2013. Fassier-Duval rods were inserted in 19 cases, K-wires in 13 cases, and Rush rods in 3 cases. Functional ability was assessed preoperatively and every year postoperatively using the self-care and mobility domains of the Pediatric Evaluation of Disability Inventory (PEDI).
Results:
The mean PEDI self-care score increased by 5.7 (P=0.028) and the mean PEDI mobility score increased by 3.6 (P=0.008) at 1-year postsurgery. Improved function was maintained in the majority of cases at a mean of 7.0 years postcorrection.
Conclusions:
Humeral rodding in children with OI leads to significant improvement in functional ability.
Level Of Evidence:
Level IV.

Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the...
