Diagnostic Criteria for Hip Microinstability Are Heterogeneous but Consistently Include Ease of Intraoperative Distraction and Physical Examination Findings: A Systematic Review.

In 30 seconds

This systematic review evaluated the diagnostic criteria for hip microinstability across 23 studies. It found that ease of intraoperative distraction and specific physical examination findings were the most consistently reported criteria. The review highlighted significant variability in diagnostic approaches, with no standardized framework established.

Key findings

• Ease of hip distraction during arthroscopy was cited in 14 studies as a diagnostic criterion.
• A positive hyperextension-external rotation test was reported in 13 studies.
• A positive prone external rotation test was noted in 8 studies.
• Substantial variability in diagnostic criteria was observed across the included studies.

Why it matters

Understanding the diagnostic criteria for hip microinstability is crucial for clinicians to accurately identify and manage this condition. The variability in criteria may impact diagnosis and treatment decisions.
