The iliopsoas apparatus will be discussed from the level of the inguinal ligament to its distal insertion. Sonographic differentiation of the individual muscle belly fibre components will be described as well as common pathological patterns. The iliopsoas bursa and injection / aspiration techniques will be discussed.

The iliopsoas tendon insertion onto the lesser trochanter is an area which is traditionally difficult to assess with ultrasound. A variety of factors including anisotropy, deep location and poor quality acoustic window through muscle belly edges result in a technical challenge. A method of sonographic assessment using the adductor longus and pectineus muscle bellies as an acoustic window will be described allowing high resolution assessment of the tendon insertion and musculotendinous junction.

The anterior hip labrum will be briefly discussed with particular reference made to the association between labral abnormalities and femoro-acetabular impingement.
