Ischio-femoral impingement

Case contributed by Dr Prashant Gupta

Presentation

Right sided buttock pain for last 2 years, not relieved by physiotheraphy.

Patient Data

Age: 45
Gender: Female
MRI

MRI PELVIS

Both ischio-femoral spaces are narrowed with edema in both quadratus femoris muscles, more on the right side.

Case Discussion

The exact cause of this syndrome is unknown, it is thought that narrowing of the Ischio-femoral space is the inciting factor, leading to edema/tears in the quadratus femoris muscle - an external rotator of the hip.

An ischio-femoral (IF) space measurement of <17mm is said to be suggestive of this syndrome. In one study by Torriani et al cases had a mean IF space measurement of 13mm vs 23mm in controls.
