Spine
-
Facet joint kinematics and capsular ligament strains were evaluated during simulated whiplash of whole cervical spine specimens with muscle force replication. ⋯ Facet joint components may be at risk for injury due to facet joint compression during rear-impact accelerations of 3.5 g and above. Capsular ligaments are at risk for injury at higher accelerations.

Descriptive methodologic recommendations. ⋯ Economic evaluations require specific methods. These recommendations may be helpful in improving the quality of economic evaluations of new and existing therapeutic interventions in the field of spinal disorders.
-
Case series. ⋯ The procedure may be less effective when performed by a variety of providers than suggested by initial case series performed by single providers or practices in work-related LBP cases. Provider self-referral and narcotic use before IDET are significant risk factors for poor outcomes. Randomized controlled trials are needed to determine whether there is a subset of patients with discogenic back pain who derive substantial and sustained benefit from this procedure.

Review Case Reports
Traumatic anterior atlantoaxial subluxation occurring in a professional rugby athlete: case report and review of literature related to atlantoaxial injuries in sports activities.
This is a case report of traumatic anterior atlantoaxial subluxation occurring in a professional rugby athlete with a literature review. ⋯ Anterior atlantoaxial subluxation in sports activities is very rare. The mechanism of this injury is hyperflexion, and the rupture of the transverse ligament is essential. Good prognosis has been reported; however, a return to high-level sports activities is thought to be a contraindication.

Randomized Controlled Trial Clinical Trial
The effect of amicar on perioperative blood loss in idiopathic scoliosis: the results of a prospective, randomized double-blind study.
A prospective, randomized, double-blind Institutional Review Board-approved study evaluating the efficacy of Amicar (epsilon aminocaproic acid), an antifibrinolytic agent, in decreasing perioperative blood loss in idiopathic scoliosis. ⋯ The results of this study confirmed that the use of intraoperative Amicar is a safe, effective, and inexpensive method to significantly reduce perioperative blood loss in patients with idiopathic scoliosis undergoing posterior spinal fusion and segmental spinal instrumentation. The results have allowed us to reduce our recommendation for perioperative autologous blood donation, thereby further decreasing costs.
