Suprascapular nerve repair is a widely-prioritized procedure for shoulder reconstruction following brachial plexus injury. Although this procedure only reconstructs glenohumeral joint motion, the standard clinical assessment of shoulder function also includes the scapulothoracic joint contribution. The purpose of this preliminary study was to develop an objective method to accurately analyze shoulder abduction following suprascapular nerve repair in brachial plexus injury patients. ⋯ The conventional measurement of shoulder global abduction with goniometer is not an appropriate method to analyze the results of suprascapular nerve repair in brachial plexus palsy patients. We recommend examination of glenohumeral and scapulothoracic motions separately with dynamic shoulder radiographic analysis. With scapulothoracic contribution to the global shoulder motion, the glenohumeral motion can be wrongly assessed.

Percutaneous vertebroplasty has been widely applied in the treatment of osteoporotic vertebral compression fractures over the past two decades. However as one of the major complications, the rate of cement leakage seems not to be decreased significantly. In this study, the rate of cement leakage was compared between two groups using two different cement injection cannulas. The purpose was to determine the efficacy of side-opening cannula on preventing cement leakage in vertebroplasty for the treatment of osteoporotic vertebral compression fractures. ⋯ Percutaneous vertebroplasty with side-opening cannula is a safe and effective minimally invasive method in the treatment of osteoporotic vertebral compression fractures, the rate of cement leakage can be significantly reduced by redirecting the cement flow.
