RESUMEN
PURPOSE: Proximal junctional failure is a complication that can occur following posterior spine surgery with instrumentation. The ability to surgically revise this complication is important for the spine surgeon, yet there is little literature on the topic, especially for pediatric patients. METHODS: The technique we describe involves proximal extension of the existing instrumentation using paired levels of sublaminar bands that allows for a smooth transition of forces at the junction of instrumented and non-instrumented regions of the spine. RESULTS: The results of this technique have been promising with a case series demonstrating improved radiographic and clinical outcomes for eight children at a minimum of 1 year follow-up. CONCLUSION: This a reliable, effective, and safe technique for salvage of PJF in children that uses posterior osteotomies and proximal extension of the instrumentation using sublaminar bands, resulting in gradual load sharing correction to restore sagittal balance.

CASE: A 7-year-old girl presented with a recurrent hammertoe deformity causing pain with shoe wearing after a prior corrective surgery. Surgical revision required a unique approach that included a staged corrective osteotomy of the proximal phalanx because of hypoperfusion management and the application of a rotational skin flap previously described for camptodactyly correction in the hand to avoid harvesting a skin graft. CONCLUSION: Revision surgery for recurrent pediatric hammertoe deformity requires a heightened awareness of the risk for toe hypoperfusion and subsequent wound closure challenges.
