Acetabular Rim Osteoplasty-Labral Takedown – Illustration
Medical illustration depicting the stages of Acetabular Rim Osteoplasty – a complex and uncommon arthroscopic surgery technique.
A minimally invasive surgical technique, arthroscopy can be used in the treatment of joint injuries. A fiber-optic camera is inserted into the joint through a small incision to enable viewing of ligaments, soft tissue and cartilage. Another small incision is made to enable removal or repair of broken or damaged tissue.
The medical illustration narrates the procedure step-by-step:
1. Surgeon using an arthroscope to inspect the cavity of the hip joint of a patient
2. Labrum lifted
3. Excess bone on the acetabular rim is shaved
4. Labral takedown
A hip arthroscopy with labral repair is performed on patients who have torn their labrum as a result of impingement in the hip (a.k.a Femoroacetabular impingement, or FAI). The torn part of the labrum is repaired and reattached to the rim of the acetabulum, recreating the hip joint suction seal.
If the labral tear is a result of FAI, then an osteoplasty (the surgical alteration or reshaping of bone) of the femoral neck, acetabular rim, or both, may be necessary. This is performed to ensure that the repaired labrum is protected and tearing of the labrum does not recur.
