Ultrasonic Welding in a Bioresorbable Implant System: Uses in Pediatric Neurosurgery

Abstract

Introduction The clinical experience with a bioresorbable fixation system that employs ultrasound as a method of fixation in pediatric neurosurgery has not been previously described. We report our experience with the use of ultrasonic fixation of PDLLA implants in our operative practice. The complications, limitations, and advantages of using this commercially available system (SonicWeld Rx, KLS Martin L.P.) will also be described. Results Over a period of 18 months, 23 consecutive patients had placements of these implants for bony fixation during craniotomies or craniofacial reconstructions. Patient age ranged from 2 months to 18 years. Types of pathologies were as follows: craniosynostosis (10); tumor (6); trauma (4); and congenital cysts (3). The only morbidity was seen in a child with Crouzon syndrome, who had a wound infection following Serratia sepsis from a central venous line infection. There were no cases of premature plate reabsorption, bony instability or settling, or skin breakdown. Ease of im...
