Why is it important?
Acetabular component positing is the major deterministic step that defines the outcome following total hip replacement. Although various methods exist to measure and maintain cup inclination, intraoperative landmarks always guide to get the individual native inclination. This study aims to estimate the safe cup depth from the transverse acetabular ligament to get an ideal cup inclination.
Perspectives
TAL can be reliably identified in all cases and can be used as a dependable intra-operative landmark for maintaining the cup inclination when the cup is positioned at a depth less than 6mm from the TAL. However, as the inclination is influenced by many factors, TAL alone cannot be used for determining the inclination of the acetabular component but can be used to guide the inclination along with other factors in play.
