Protrusio acetabuli is a deformity characterized by the medial displacement of the femoral head into the pelvic cavity 1. This condition can occur in the setting of arthropathies or other conditions 1.

Diagnosis

  • Detection of protrusio acetabuli is readily achievable with standard anteroposterior hip or pelvis radiographs 1.
  • Radiographs allow for the description of normal radiographic anatomic relationships and their distortion in protrusio acetabuli 1.

    • Management

  • No management strategies are described in the provided abstracts.

    • Special Populations

  • No information is available for special populations.

    • Key Recommendations

  • Standard anteroposterior hip or pelvis radiographs readily permit the detection of protrusio acetabuli 1. (Evidence: Expert opinion)
  • Radiographic findings can describe normal anatomic relationships and their distortion in protrusio acetabuli 1. (Evidence: Expert opinion)
  • The occurrence of this deformity in arthropathies is stressed, and other entities are mentioned and illustrated 1. (Evidence: Expert opinion)
