Operative Time is an Independent Risk Factor for Complications in Adult Spinal Deformity Surgery

The prevalence of Adult Spinal Deformity (ASD) is increasing as the demographic of Western societies shift towards a more elderly population [1]. As the spine ages, multiple degenerative changes occur within this complex support structure. Adult spinal deformity is often the result of progressive degenerative changes. A growing financial burden on the healthcare system exists with the rising prevalence of ASD and a commensurate increased rate of surgical treatment for the condition. Surgical treatment for ASD is reserved for patients whose pain and disability have not responded to nonoperative care and often requires extensive reconstruction [2-5]. While numerous studies have demonstrated the clinical benefits of surgical treatment for ASD, these procedures are not without significant risks and cost [6-8]...
