Hip Joint Effusions
- Diff Dx:
- Intracapsular Fractures
- Toxic Synovitis of the Hip
- Septic Arthritis
- Legg Perthes disease in children.
- Clinical Features:
- person suffering from a painful Hip Joint effusion is most comfortable when seated with the painful thigh lightly abducted and externally rotated at the hip joint;
- this orientation reduces tension in synovial membrane to minimum because it maximizes encapsulation of femoral head by acetabular cavity and labrum;
- Radiographic Features:
- most sensitive indicator of Hip Joint effusion in AP radiograph is inferolateral displacement of femoral head from acetabular cavity;
- in children: look for medial displacement of psoas line or obturator line
