Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Cases

Patients that have symptomatic psoas impingement in a protruding acetabular cup documented by a Pelvis CT scan

Pelvis CT scan

Intervention Type DIAGNOSTIC_TEST

Post-THA hip pelvis CT scan execution for pain, noise or THA planning for the controlateral hip, with identification of acetabular cup protrusion. Comparation of cases and controls to identify radiological factors that could potentially lead to symptomatic psoas impingement prediction.

Controls

Asymptomatic patients with a protruding acetabular cup documented by a Pelvis CT scan

Pelvis CT scan

Intervention Type DIAGNOSTIC_TEST

Post-THA hip pelvis CT scan execution for pain, noise or THA planning for the controlateral hip, with identification of acetabular cup protrusion. Comparation of cases and controls to identify radiological factors that could potentially lead to symptomatic psoas impingement prediction.
