Comparative Study
A biomechanical comparison of different fixation techniques for fractures of the acetabular posterior wall.
This study aimed to evaluate the biomechanical stability of different fixation techniques for fractures of the acetabular posterior wall. The hypothesis was that a reconstruction plate, combined with compression screw fixation and a plate placed lateral to the screws, would achieve a higher peak load to failure and stiffness and reduced gapping during cycle loading than other fixation techniques. ⋯ Fixation using a reconstruction plate and compression screws placed lateral to the screws may address acetabular posterior wall fractures in a more appropriate manner than techniques using only plates or screws. However, this study does not provide evidence to support the fact that placing the plate lateral to the screws is advantageous in comparison with other techniques.

Randomized Controlled Trial
The efficacy and safety of two low-dose peri-operative dexamethasone on pain and recovery following total hip arthroplasty: a randomized controlled trial.

The purpose of this study was to investigate glenoid morphology and define the safe zone for protecting the suprascapular nerve baseplate screw during baseplate fixation in reverse shoulder arthroplasty (RSA) in a Chinese population. ⋯ Glenoid size and the safe zone for screw fixation during RSA were characterized in a Chinese population. Careful consideration of baseplate fixation and avoidance of suprascapular nerve injury are important for improved clinical outcome.
