Functional Evaluation of Endoscopic Treatment of Ischiofemoral Impingement: Case Reports.

Ischiofemoral impingement (IFI), although infrequent, should be thought of as one of the causes of deep gluteal pain syndrome. Difficulty in establishing a diagnosis and inaccurate clinical examination can be associated with the small number of case reports in the literature. The initial IFI treatment uses conservative measures, and surgical treatment is infrequent.
