OBJECTIVE Fusions across the cervicothoracic junction have been challenging because of the large biomechanical forces exerted resulting in frequent reoperations for nonunions. The objective of this study was to investigate a retrospective cohort using chart review of posterior cervicothoracic spine fusions with and without bone morphogenetic protein (BMP) and to determine the reoperation rates for symptomatic nonunions in both groups. METHODS Between January 2009 and September 2013, posterior cervicothoracic spine fusion cases were identified from a large spine registry (Kaiser Permanente).

Background: Several studies have shown excellent fusion rates in occipitocervical (OC) fusions, but very little is reported on mortality and reoperation rates in elderly patients. Our article reports these rates in elderly patients from a national spine registry with a >2-year follow-up period.

Methods: Using data from a spine implant registry developed at a large integrated health care system (Kaiser Permanente), elderly patients (aged ≥ 65 years) with instrumented OC fusions between January 1, 2009 and September 30, 2013 were identified.

Study Design: A retrospective cohort study with chart review.

Objective: To determine the reoperation rates for symptomatic nonunions for 1-level, 2-level, and 3-level anterior cervical discectomies and fusions (ACDFs) from a national spine registry.

Summary Of Background Data: There is very little data reported in the literature on reoperation rates for symptomatic nonunions after ACDFs.
