Block of the Pericapsular Nerve Group of the Hip with and without Ultrasound Guidance: Comparative Cadaveric Study.

 To evaluate the technical reproducibility of a block of the pericapsular nerve group (PENG) of the hip aided or not by ultrasound in cadavers.  The present is a randomized, descriptive, and comparative anatomical study on 40 hips from 2 cadaver groups. We compared the PENG block technique with the method with no ultrasound guidance.

Depression fractures of the posterolateral tibial plateau: Treatment by lateral femoral epicondyle osteotomy approach.

Objective: The best surgical exposure and fixation method for fractures affecting the posterolateral corner of the tibial plateau remain debatable. This study describes a surgical approach to treat lateral depressions of the posterolateral tibial plateau with or without rim involvement by osteotomy of the lateral femoral epicondyle associated with osteosynthesis with a one-third tubular horizontal belt plate to stabilize the fracture fragment.

Method: We evaluated 13 patients with fractures of the tibial plateau affecting the posterolateral region.
