Summary
The purpose of this study is to identify radiological factors on TC of the hip that could lead to prediction of development of symptomatic psoas impingement in patients with protruding acetabular cup after primary total hip arthroplasty.
Eligibility Criteria
Inclusion Criteria
- Primary total hip arthroplasty
- Execution of a postoperative Ct scan for pain, noises or planning of the contralateral THA
- 5 years minimum follow-up for the control group, tenotomy of the iliopsoas muscle in the cases group
- Complete clinical and radiological data
Exclusion Criteria
- Patient's refusal to participate
- Non adequate Ct scans or made for periprosthetic fractures, component mobilization, periprosthetic infection or wearing of the prosthesis
- Incomplete clinical and radiological data
- Inadequate follow-up or regression of the iliopsoas impingement symptoms with non-operative treatment
