Efficacy of aprotinin as a blood conservation technique for adult deformity spinal surgery: a retrospective study.

Study Design: A retrospective study that involved a total of 82 adult deformity patients who underwent spinal fusion surgery with instrumentation of 6 or more levels.

Objective: The purpose of this study is to assess the efficacy and safety of aprotinin in reducing blood loss in adult spinal deformity patients.

Summary Of Background Data: Aprotinin is an antifibrinolytic agent, which has been proven to be effective as a blood-conserving agent in cardiac surgery.

The reliability and diagnostic value of radiographic criteria in sagittal spine deformities: comparison of the vertebral wedge ratio to the segmental cobb angle.

Study Design: A prospective, radiographic cohort study.

Objectives: This study assessed the radiographic reliability and diagnostic value of the vertebral wedge ratio (WR) to the more segmental Cobb angle (CA) regarding sagittal spine deformities.

Summary Of Background Data: The use of the CA has been used to assist in the radiographic diagnosis of various sagittal spine deformities.
