Trends in epidemiology and management of type II odontoid fractures: 20-year experience at a model system spine injury tertiary referral center.

Study Design: A retrospective cohort study of consecutive type II Odontoid fractures presenting to a Level 1 Regional Model Systems Spinal Cord Injury Center between June 1985 and July 2006.

Objective: To assess trends in management of type II Odontoid fractures presenting to a Level 1 Model Systems Regional Spinal Cord Injury Center over a 20-year period.

Summary Of Background Data: Type II Odontoid fracture management is controversial, and a majority of studies have had relatively small cohorts.

Percutaneous vertebral compression fracture management with polyethylene mesh-contained morcelized allograft bone.

Study Design: A comprehensive systematic review of the literature.

Objectives: To assess the modern literature on the use of polyethylene mesh-contained morcelized allograft (PMCMA) bone for spinal fusion and vertebral compression fracture management.

Summary Of Background Data: There are presently no systematic reviews of PMCMA.

Early complications of surgical versus conservative treatment of isolated type II odontoid fractures in octogenarians: a retrospective cohort study.

Study Design: A retrospective cohort study of operative versus nonoperative treatment of isolated type II odontoid fractures in patients aged 80 years and more without neurologic deficit admitted to a level 1 spinal cord injury center between June 1985 and July 2006.

Objective: To assess the presentation and acute complications of operatively and nonoperatively managed type II odontoid fractures in the octogenarian population.

Summary Of Background Data: Type II odontoid fractures are the most common cervical spine fracture in the elderly.
