Background
Subspine impingement (SSI), involving abnormalities of the anterior inferior iliac spine (AIIS), is a recognized cause of hip pain and often treated arthroscopically, frequently alongside other hip preservation procedures.
Methods
Systematic review of literature on arthroscopic subspine decompression, focusing on patient characteristics, outcomes, and complications.
Key Findings
- SSI decompression is mostly performed with other hip surgeries (e.g., for FAIS).
- The subspine impingement test is the most common diagnostic tool.
- Patients typically experience improved hip function and PROs after surgery.
- Study quality and methodologies vary considerably.
Conclusions
Arthroscopic subspine decompression is effective, especially combined with other procedures, but more high-quality research is needed.
What Does This Mean for Providers?
Providers should consider subspine decompression as part of a comprehensive hip preservation strategy in patients with confirmed SSI, especially when combined with treatment for concomitant FAIS. However, clinicians should remain cautious due to heterogeneous study quality and tailor interventions based on thorough clinical and imaging evaluation.
