Partial displacement of a bone from its joint is a medical subluxation. Complete displacement of a bone from its joint is a dislocation.
Dislocation is displacement of a bone from its joint, and subluxation is partial displacement of a bone from its joint. There are many structures that hold a joint in it's place, one of these is ligament which is a rigid and somewhat flexible structure, and capsule surround a joint which is filled with synovial fluid. When a force want to displace the joint for example during jumping or anything like this these structures prevent the joint from being displaced.

The joint between the sacrum and the hip bone is the sacroiliac joint. It is also known as the SI joint. They form the articular surfaces.
The metacarpophalangeal joint is typically known as the pastern. This is the joint between the metacarpus (cannon bone) and the first phalanx (the pastern bone).
The jaw joint, also known as the temporomandibular joint (TMJ), includes the mandible (lower jaw bone) and the temporal bone (part of the skull).
A displacement of two major bones of the foot (hallux valgus) causes bunions, although not everyone with this displacement will develop the joint swelling and bone overgrowth that characterize a bunion.
It is known as the thumb basal joint, also known as the carpometacarpal joint. It is a special saddle-shaped joint that is formed by the small wrist bone and the first of the three bones in the thumb.
X rays can help confirm the diagnosis by showing the bone displacement, joint swelling, and, in some cases, the overgrowth of bone that characterizes bunions.
The femur is the biggest bone in the body and is known as the thigh bone in common terms. The humerus is the bone that is attached to The scapula by the glenohumeral joint.
No. The pop is caused by a partial vacuum being created in the joint, which is quickly filled by fluid and air.
The tibia, or shin bone, is not a joint.
