Study Design: Retrospective chart review.

Objective: To accurately determine complication rates, particularly mortality rates, in surgically treated early-onset scoliosis.

Summary Of Background Data: The advent of modern segmental instrumentation for spinal fusion surgery in adolescent scoliosis has allowed for application of similar nonsegmental unfused techniques aimed at controlling scoliosis in the very young child.

Study Design: Retrospective review of a prospectively collected, multicenter database.

Objective: To assess rates of new neurologic deficit (NND) associated with spine surgery.

Object: This is a retrospective review of 10,242 adults with degenerative spondylolisthesis (DS) and isthmic spondylolisthesis (IS) from the morbidity and mortality (M&M) index of the Scoliosis Research Society (SRS). This database was reviewed to assess complication incidence, and to identify factors that were associated with increased complication rates.

Methods: The SRS M&M database was queried to identify cases of DS and IS treated between 2004 and 2007.

Study Design: Retrospective review of a prospectively collected database.

Objective: The Scoliosis Research Society (SRS) collects morbidity and mortality (M and M) data from its members. Our objectives were to assess complication rates for 3 common spine procedures, compare these results with prior literature as a means of validating the database, and to assess rates of pulmonary embolism (PE) and deep venous thrombosis (DVT) in all cases reported to the SRS over 4 years.
