“…Two in vitro studies and four experimental animal trials have been carried out that demonstrated the excellent stability and handling characteristics of the osteosynthesis system (Table 2 6,16,17,21,22,26 ). The clinical studies that were performed on pediatric craniosynostosis patients also showed favourable outcomes with low complication rates (Table 3 4,5,7,24 ).…”

SummaryUltrasound activated resorbable pin osteosynthesis (UARPO) has recently shown favourable results in operations on children suffering for craniosynostosis. However, data on complications coming with this new technique in children suffering from craniosynostoses are scarce and have only been assessed retrospectively so far. It has been the aim of the present study to prospectively follow up children undergoing craniosynostosis surgery with a focus on complications related to UARPO materials.Ten pediatric patients (3 female/7 male) were operated due to craniosynostosis at an average age of 9.1±3.8 months using UARPO (SonicWeld/Resorb-X, KLS Martin, Tuttlingen, Germany). Clinical followup evaluations were carried out 1, 3, 6, 9, 12 and 18 months after surgery according to signs of local infection, stability of the remodeled cranial vault and the palpability of the osteosynthesis material. If secondary surgery was necessary, the indication was documented and evaluated by histological and wound smear examinations.No intra-operative or postoperative complications during the inpatient period occurred. 3 patients needed secondary operation due to a localized chronic swelling at the former incision site which developed 3, 9 and 12 months after the operation. Histological examinations yielded a giant cell formation surrounding the resorbable materials in all cases. Additionally, the wound smear showed a bacterial infection in one site.The current prospective study is the first in the field. It reveals a high percentage of delayed foreign body reactions with UARPO, bearing the need of secondary surgery. It seems that this high complication rate found in the present prospective study may weigh out the advantages of UARPO.KEY WORDS. Craniofacial surgery. Craniosynostosis. Resorbable materials.

“…Rigid fixation with titanium miniplates was reportedly a superior technique when compared with resorbable miniplates [11][12][13] . Therefore, the present study focused on evaluating the biomechanical stability characteristics of titanium miniplates of varied shapes instead of evaluating rigid fixation methods.…”

“…This problem has been overcome by inserting pins instead of screws with the aid of ultrasound. It has been shown previously that the operation time required for applying osteosynthesis materials was reduced by 50% 21 . Since the pins are not exposed to tensional forces the material does not fracture 21 .…”
