Thread: Tax credit Phone number. Tax credit Phone number Does anyone know the freephone number for the tax credit office? I'm sure someone put the number on here but I can't find it. I've got the 0845 number but they keep you hanging on for so long I wanted to ring a freephone number. Thanks.

Best Answer: It can be referred to as the acetabulofemoral joint, since it is formed by the acetabulum, forming the hip socket of the pelvis, and the head of the femur, which articulates within the socket. In describing deformities affecting the hip joint, the term coxa is used.
The head of the femur articulates with the os coxa (pelvis) at the  acetabulum. The acetabulum is the rounded socket that the head of  the femur fits into. It also allows sl â¦ iding of the pelvic bones and  rotation. This joint is a synovial joint and is an example of a  ball-and-socket joint.
