Ball and socket joint Ball and socket joint The ball and socket joint (or spheroid joint) is a type of synovial joint in which the ball-shaped surface of one rounded bone fits into the cup-like depression of another bone. The distal bone is capable of motion around an indefinite number of axes, which have one common center. It enables the bone to move in many places (nearly all directions). An enarthrosis is a special kind of spheroidal joint in which the socket covers the sphere beyond its equator. Examples of this form of articulation are found in the hip, where the round head of

Development of blood clots (deep-vein thrombosis) is also a risk, probably created by the slowing of blood flow in the veins as a result of reduced mobility. Damage to nerves around the hip joint can occur, sometimes because of direct damage with the surgical instruments, or as a result of the traction needed to gain access to the joint. For this reason, surgeons prefer to apply as little traction as possible, for as short a time as possible, in order to gain safe access to the joint. The most common
