Trendelenburg Gait

Description

Dr Jonathan Vigdorchik gives his insights into complications that can arise after a total hip arthroplasty, particularly focusing on issues related to the abductor muscles, namely the gluteus medius and minimus. He explains that damage to these muscles can occur during surgery, especially with the anterolateral approach where these muscles may be detached. The narration explains the importance of preserving the superior gluteal nerve and the implications if it is damaged, leading to potential dysfunction post-surgery.



Key anatomical concepts are introduced, highlighting how improper surgical technique or failure to restore the proper offsets can affect muscle tension and overall function of the hip. The discussion further illustrates how improper alignment (like a valgus thumb position or short neck length) decreases the global offset, impacting the gluteus medius. These issues manifest in specific gait patterns where the pelvis tilts to one side when stepping, indicating weakness in the abductor muscles. Overall, Dr Vigdorchik emphasizes the critical role of surgical precision and anatomy in the recovery and functionality of patients post-hip arthroplasty.
