![]() The main indications for HF range from pre-surgical correction to postoperative fusion support. ![]() HF is in widespread use to treat a variety of disorders and pathologies in children and adults. The use of halo fixation (HF) to treat cranio-cervical instability was first described in 1968. The current data show that, when used according to the appropriate indication, HF is an effective conservative treatment option for cranio-cervical instability, associated with only minor complications. Only minor complications were reported, such as pin infections. ![]() Evaluation according to the underlying pathology showed that, except for atlanto-occipital dislocation, HF generates high fusion rates among different patient cohorts, mainly in C2 vertebra injuries and atlantoaxial rotatory subluxation. The overall success rate of HF was very high. C2 is the most frequently injured vertebra in children. The general success rate, the success rate related to underlying pathologies, and complication rates were evaluated. Searches were performed in PubMed, MEDLINE and Embase databases for the years from 2010 to 2020. We analyzed studies describing the use of HF in traumatic injuries of the cranio-cervical junction in children under the age of 17. The goal of this systematic review was to find out whether, over the last 10 years, halo fixation (HF) could still be considered a successful treatment option without major risks or complications. The aim of therapy is to restore cervical stability without limiting the range of motion. Traumatic cranio-cervical instability in childhood is rare and constitutes a challenge for the treating surgeon.
