Why the study?
There are no particular techniques for femoral head translation assessment, which leads to cam deformity development and femoroacetabular impingement.
Does the Gamma angle measurement method accurately assess femoral head translation in adults with cam or mix form of femoroacetabular impingement?
Does the Gamma angle measurement method accurately assess femoral head translation in adults with cam or mix form of femoroacetabular impingement?
The study introduces the Gamma angle as a novel method to test femoral head translation in adults with femoroacetabular impingement.
Answers are grounded in this paper and cite their sources.
Gamma angle may quantify femoral head translation in FAI; leaves open reliability and clinical utility pending validation.
Femoral head translation leads to the cam deformity development. It is formed on the femoral head-neck junction. Cam deformity produces femoroacetabular impingement. There are no particular techniques for femoral head translation assessment. The offset index is the most regularly applied. It quantifi es the relation between the femoral head and neck junction. We introduce the original method to test the femoral head translation.
