Low-volume surgeons experienced significantly greater odds of inpatient surgical complications, as well as increased risk of revision during long-term follow-up with a significantly increased risk of implant malfunction at 10 years post-operatively. LEVEL OF EVIDENCE Level III.STUDY DESIGN Single-center retrospective review of pediatric patients who underwent posterior spinal fusion for adolescent idiopathic scoliosis (AIS). OBJECTIVE To determine what clinical and operative factors influence inflation-adjusted hospital costs of posterior spine fusion surgery for AIS. With rising healthcare costs and the advent of bundled payments, it is essential understand the predictors of costs for surgical procedures. We sought to determine the components of hospital costs for AIS posterior spine fusion surgery using standardized, inflation-adjusted, line-item costs for services and procedures. METHODS The study population comprised 148 AIS patients who underwent spinal fusion surgery at a large tertiary care center between 2009 and 2016. Data on medical characteristics, curve type, curve magnitude, number of screws and the number of levels was collected through manual chart review of X-rays and medical records. Hospital costs from admission until discharge were retrieved from an institutional length of stay, and reducing intraoperative costs. LEVEL OF EVIDENCE III.Dermatomyositis is a rare inflammatory disease with characteristic cutaneous findings and varying amounts of systemic involvement. Patients may present with skin disease alone, have concomitant muscle disease, or have extracutaneous manifestations such as pulmonary disease or an associated malignancy. Given such diverse presentations, dermatomyositis is both a diagnostic and therapeutic challenge. However, a prompt diagnosis is of utmost im
