complications of halo vest orthosis: a narrative study

Background and aim: perry and nickel introduced the halo vest in 1959. it is the mostcommon immobilization device for the unstable cervical spine. in the literature review, mostarticles review the beneficial effects of the halo vest, and a few report its complications. thisstudy aims to evaluate the complications associated with halo orthosis.methods and materials/patients: this is a narrative study about halo vest complications. toprovide up-to-date information, we reviewed the articles written about halo complications.all relevant articles were retrieved from google scholar, medline, pubmed, etc., using thekeywords of “halo vest orthosis”, “unstable cervical spine fracture”, “halo vest complications”,“halo vest immobilization”, “pin-site-related complications”, and “vest-related complications”.afterward, we reviewed and critically analyzed the articles.results: at first, the halo vest was used for postoperative paralyzed poliomyelitis patients, andlater, it was also used for traumatic injury of the cervical spine or postoperatively in cervical spinereconstructive surgery. compared to other orthoses, the halo vest provides a more effectiveexternal fixation and maintains normal anatomic alignment of the cervical spine withoutimpacting jaw motion and resulting in eating problems. however, it has many temporarycomplications. to prevent halo vest complications, experienced people should apply it, and thepatients should be regularly followed up for early detection and treatment of complications.conclusion: our review is the starting point for the evaluation and investigation of halo vestcomplications. because of the high incidence of pin loosening and infection, it is better toevaluate the design and application of halo pin. since the initial design of the halo vest, onlyits superstructure has been redesigned without any significant change in other parts of it.
