Surgical Site Infection Following the Correction of Adolescent Idiopathic Scoliosis With ApiFix: A Retrospective Study Analyzing Its Incidence and Recurrence

Background and objective ApiFix (OrthoPediatrics, Warsaw, IN) is an internal brace used for the correction of adolescent idiopathic scoliosis (AIS) classified as Lenke 1 or 5 with a Cobb angle of 35-60 degrees that decreases to ≤30 degrees on lateral side-bending radiographs. Since the indications are very specific, it is not a common procedure. Our study aimed to evaluate the incidence of surgical site infection (SSI) and its recurrence following treatment with ApiFix. Materials and methods A retrospective study of 44 cases of AIS treated at our center from 2016 to 2022 with ApifiX was conducted. Two patients who presented with SSI were initially treated with irrigation and debridement (I&D) following antibiotic therapy.  Results A total of 44 patients with a mean age of 15.1 years were evaluated. Two of our patients presented with early-onset infection while one of them presented after the end of treatment with a skin ulcer due to septic screw loosening. The removal of the ApiFix implant revealed a pedicle abscess during the screw removal. Conclusions In this study of 44 patients, we observed two cases of infection and one case of reinfection. Given the limited muscle detachment and short operating time needed for Apifix, statistics suggest that the risk of SSI is always present. Further randomized trials are needed to gather more evidence on this subject.

Cervical Necrotizing Fasciitis: An Institutional Experience

Introduction Cervical necrotizing fasciitis is an acute, progressive, and rapidly spreading soft tissue infection affecting the fascial planes of the head and neck region. It has high morbidity and mortality rate. In this study, we have reviewed cervical necrotizing fasciitis cases treated in our department and analyzed the various risk factors, laboratory indices, and treatment modalities that affect the prognosis of this deadly disease. Design and method This is a retrospective review. We have reviewed the medical records and charts of seven patients hospitalized in our institute with the diagnosis of cervical necrotizing fasciitis between 2015 and 2019. Results Of the seven patients, six were male and one was female. The mean age was 49.8 years (range: 38-70 years). Etiology was found to be odontogenic infection in five (71%) cases. The presenting feature in all cases was tender cervical swelling. Intraoperatively, the submandibular triangle was found to be involved in all cases (100%) followed by the carotid triangle in five (71%) cases and the submental triangle in three (42%) cases. The most common comorbidities associated with cervical necrotizing fasciitis were found to be uncontrolled diabetes mellitus and anemia. All patients underwent emergency aggressive surgical debridement and culture-directed broad-spectrum antibiotics (100%). Additional procedures in the form of tracheostomy were required in two (28%) cases and skin grafting in two (28%) cases. One patient in our series developed sepsis with descending mediastinitis. The average hospital stay was 27 days. All the patients survived with no mortality. Conclusion Cervical necrotizing fasciitis should be diagnosed early. Early initiation of broad-spectrum antibiotics and aggressive surgical debridement are the two key management strategies that can improve survival. Strict glycemic control and correction of anemia result in a favorable outcome.
