Abstract
A minimally invasive hip joint and a joint replacing method are provided. The minimally invasive hip joint includes a threaded rod and a joint body including a plurality of elastic sheets, with their top ends being all disposed at a top end position of the threaded rod, and bottom ends being all movably sleeved on the threaded rod and dispersedly distributed along the circumferential direction of the threaded rod; and the threaded rod is threadedly engaged with a locking component located at the below position of the elastic sheets. The joint replacing method comprises replacing a damaged or undamaged femoral head on a femur with the aforementioned minimally invasive hip joint. When replacing a damaged or undamaged femoral head with the minimally invasive hip joint, it is only necessary to drill at the outer side of the trochanter major and rotate the locking component.
