Abstract

STUDY DESIGN: A retrospective clinical study. PURPOSE: To analyze the surgical outcomes of intraoperative halo-femoral traction (HFT) in patients with adolescent idiopathic scoliosis (AIS) with Cobb angles between 70° and 90° and flexibility <35%. OVERVIEW OF LITERATURE: Numerous methods have been described to achieve adequate correction and successful results in the surgical treatment of AIS patients with a Cobb angle >70°. However, few studies have evaluated the results of HFT in AIS patients with Cobb angles between 70° and 90° and flexibility <35%.
METHODS
The study comprised 24 AIS patients (18 females, six males; mean age, 17.4 years; mean preoperative Cobb angle, 80.1°; range, 70°-90°) who underwent surgery using intraoperative HFT. Neurological status was constantly assessed during the surgery using intraoperative neurophysiological monitoring.
RESULTS
The mean follow-up period was 33.5 months. Radiographic outcomes demonstrated 85.7% correction of the major Cobb angle. Coronal and sagittal balance was achieved in all the patients, and shoulder levels were equalized. The traction was discontinued when a decrease in spinal cord potentials was observed during the surgery.
CONCLUSIONS
Intraoperative HFT is an effective and reliable method for the management of scoliosis curves between 70° and 90°. The most significant advantages of the method are avoidance of the morbidities related to anterior surgery, osteotomy, or vertebral column resection; its contribution in helping achieve adequate reduction and optimum balance by the gradually increased corrective force, lack of any need for extreme correction force during instrumentation; and the high correction rates achieved.
