Hope Springs Eternal: Insights Into the Durability of Springs to Provide Long-Term Correction of the Scaphocephalic Head Shape

Spring-mediated cranial vault expansion (SMC) has become a primary treatment modality at our institution to correct scaphocephalic head shape in the setting of isolated sagittal craniosynostosis (CS). Spring-mediated cranioplasty is associated with minimal procedural morbidity and reliable clinical efficacy, although long-term outcomes are not well elucidated. Herein we describe our institutional experience and lessons learned with SMC. We hypothesize that SMC performed in young infants offers durable scaphocephalic correction as measured by cephalic index (CI) at the 1, 3, and 5-year postoperative timepoints. Patients with isolated sagittal CS who underwent SMC at our institution during an 8-year period were retrospectively studied. The primary outcome measure was long-term head shape determined by CI at the 1, 3, and 5-year postoperative timepoints. Secondary outcomes included patient and spring factors associated with change in CI, including age and spring force. All statistical tests were 2-tailed with P
