[Effectiveness of peripheral nerve blockade in pain management for patients undergoing anterior cruciate ligament reconstruction: a retrospective observational study].

Introduction: therapeutic equivalence has been established in the effectiveness of peripheral nerve blocks in the management of pain in the postoperative period of anterior cruciate ligament reconstruction. However, it is unknown whether this effect is modulated by the anesthesiologist's experience. The objective was to describe the effectiveness of peripheral nerve blocks during the first 24 hours of the postoperative period, considering patient characteristics and the anesthesiologist's experience.

A novel radiographic index for the diagnosis of posterior acromioclavicular joint dislocations.

Background: Posterior acromioclavicular (AC) joint dislocations are frequently misclassified because posterior translation of the clavicle is difficult to evaluate in Zanca radiograph views. A novel radiographic index was used in this study to accurately diagnose posterior dislocations of the AC joint.

Hypothesis: This novel index has a high degree of accuracy for the diagnosis of posterior AC joint dislocations.
