Fitted with a ball-and-socket joint for mounting on a tripod, and complete with wooden field case. |
The ball-and-socket joint, also known as a spheroidal joint, is the only one with three types of movement. |
Regardless of the chosen system, a primary THA replaces the proximal femur, including the femoral head, and resurfaces the acetabulum, creating a new ball-and-socket joint. |
A leveling head or ball-and-socket joint on the top of the tripod will be found of material aid in leveling the instrument. |
The hip joint is a ball-and-socket joint because the spherical head of the femur moves inside the cup-shaped acetabulum. |
Supported on a tripod by means of a ball-and-socket joint and screw-tightening device. |
