Central Coalition Osteotomy of Phalangeal Synostoses in the Management of the Type III Apert Hand.

Abstract

We report a technique in the management of the type III Apert hand. The proposed approach facilitates the creation of a 5-fingered hand in 3 stages. We reviewed records of patients with Apert syndrome and type III hands surgically treated at our institution from 1995 through 2014. In all cases, syndactyly release was performed in 3 stages with prioritization of the border digits. In addition, limited retrograde, axial osteotomies between the phalangeal segments of the conjoined index, middle, and ring fingers were performed during the first stage. Medical records were reviewed for demographics, clinical presentation, operative findings, and postoperative outcomes. Twelve pediatric patients with type III hands underwent syndactyly release. Median patient age was 10.0, 15.8, and 29.6 months at operative stages 1, 2, and 3, respectively. A thumb and 4 fingers were achieved for all but 1 hand. The median duration of hospital stay was 2 days for each stage. No infections or major complications were observed. We demonstrate this method as a safe and effective means of creating 5 digits in the Apert patient with type III hands. Our opinion is that the additional aesthetic and functional gains offset the requirement of a 3-stage approach. Therapeutic IV.
