KEY POINTS: FAI MORPHOLOGY & ADOLESCENT SPINES

• There is a significant association between between spinal deformity and the presence of femoroacetabular impingement morphology. 

There was no relationship between femoroacetabular impingement morphology and spinopelvic parameters.

• Abnormal morphology or biomechanics in the pelvis or spine inherently affect each other by way of the lumbosacral junction.
• Changes in spinal alignment alter hip biomechanics and may also predispose an...

Differences in Hip Strength, Gluteus Medius Activity, and Trunk, Pelvis, and Lower Limb Biomechanics During Different Functional Tasks.

Komsak Sinsurin, Raul Valldecabres & Jim Richards (2020) An exploration of the differences in hip strength, gluteus medius activity, and trunk, pelvis, and lower-limb biomechanics during different functional tasks, International Biomechanics, 7:1, 35-43, DOI: 10.1080/23335432.2020.1728381

This small study of healthy volunteers explored differences in the coronal biomechanics of the trunk, pelvis, hip, and knee joints, as well as gluteus medius muscle activity during walking and step down tasks.

Key Points 

• Functional impairment of glute med can lead to excessive lateral trunk bending, which is often observed...
