Reconstructive joint surgery can result in significant improvement in the quality of life for patients. Our goal is to restore joint function, prevent further injury and alleviate debilitating pain.
A joint is the area where two bones are attached for the purpose of motion of body parts. A joint is usually formed of fibrous connective tissue and cartilage. An articulation or an arthrosis is the same as a joint.
Joints are grouped according to their motion: a ball and socket joint, a hinge joint, a condyloid ( a joint that permits all forms of angular movement except axial rotation); a pivot joint, gliding joint, and a saddle joint.
Joints can move in four ways:
- Gliding ??“ One bony surface glides on another without or rotator movement;
- Angular ??“ occurs only between long bones, increasing or decreasing the angle between bones;
- Circumduction ??“ occurs in joints composed of the head of the bone and an articular cavity, the long bone describing a series of circles, the whole forming a cone; and
- Rotation ??“ a bone moves about a central axis without moving from this axis
