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

Video Transcription

Video Summary

The video is a presentation on hip micro-instability by an undisclosed speaker. The speaker begins by acknowledging that five minutes is not enough time to discuss the topic in-depth but provides an overview. Hip micro-instability is defined as extra-physiologic hip motion that causes pain with or without the symptom of hip joint unsteadiness. The speaker highlights the research showing that the femoral head moves relative to the acetabulum and discusses studies that demonstrate subluxation in ballet dancers and the role of capsular ligaments in controlling motion. The speaker also mentions models of hip capsular laxity and the spiral effect of breakdown in the labrum and capsule. Furthermore, the speaker explains the evolving understanding of how to diagnose hip micro-instability, including history, physical tests, radiographic findings, and MRI criteria. In conclusion, the speaker emphasizes that hip micro-instability is a real condition and ongoing research is improving its diagnosis.
