Hip Microinstability: What Is It and How Do We Diagnose It?

Video Transcription

Video Summary

In this video, the speaker discusses hip micro-instability and how to diagnose it. The concept of hip micro-instability refers to extra-physiologic hip motion that causes pain, with or without the symptom of hip joint unsteadiness. The speaker explains that the femoral head moves relative to the acetabulum, leading to stress on the capsule and labrum. Various tests, such as the hip abduction extension external rotation test and the prone external rotation test, can be used to diagnose hip micro-instability. Radiographic findings, such as the lateral and anterior center edge angles, can also help in the diagnosis. The speaker concludes by stating that while there is increasing ability to diagnose hip micro-instability, more research is needed to further improve diagnostic methods. No specific credits were mentioned in the video.
