    ABSTRACT: The utility of intraoperative radiographs after posterior spinal segmental instrumentation for adolescent idiopathic scoliosis (AIS) is debatable. A retrospective review of 74 patients with moderately severe AIS revealed the main thoracic Cobb measurements of 57° preoperatively, 17° intraoperatively, 18° on initial postoperative, and 20° on final postoperative radiographs. On the basis of the extent and type of instrumentation (pedicle screws vs. hybrid construct), there was no clinically significant difference in curve magnitude between intraoperative and postoperative radiographs. After posterior segmental instrumentation for moderate AIS, frontal plane correction measured on intraoperative supine radiographs are comparable with similar measurements made on full-length postoperative standing radiographs.

    ABSTRACT: Ankylosing Spondylitis (AS) is a multifactorial and polygenic rheumatic condition without a well-understood pathophysiology (Braun and Sieper (2007)). It results in chronic pain, deformity, and fracture of the axial skeleton. AS alters the biomechanical properties of the spine through a chronic inflammatory process, yielding a brittle, minimally compliant spinal column. Consequently, this patient population is highly susceptible to unstable spine fractures and associated neurologic devastation even with minimal trauma. Delay in diagnosis is not uncommon, resulting in inappropriate immobilization and treatment. Clinicians must maintain a high index of suspicion for fracture when evaluating this group to avoid morbidity and mortality. Advanced imaging studies in the form of multidetector CT and/or MRI should be employed to confirm the diagnosis. Initial immobilization in the patient's preinjury alignment is mandatory to prevent iatrogenic neurologic injury. Both nonoperative and operative treatments can be employed depending on the patient's age, comorbidities, and fracture stability. Operative techniques must be individually tailored for this patient population. A multidisciplinary team approach is best with preoperative nutritional assessment and pulmonary evaluation.
