Arthrodesisarthrodesis[är′thräd·ə·səs]Arthrodesisan operation that completely immobilizes a joint with the object of restoring an extremity’s supportive capability lost in certain diseases or injuries. Loss of supportive capacity may occur as a result of improperly knitted joint fractures, in tuberculosis, and in other acute and chronic joint inflammations. Arthrodesis consists in removing the cartilaginous surfaces (sometimes resecting the articular extremities of bones) and then fixing the joint surfaces in close contact until they knit. Knitting of the joint extremities may be accelerated by the compression method—compressing the joint ends with a special apparatus after removing the articular cartilage or after resecting the articular extremities of the bone.

Indications Differ according to the joint: ankle arthrodesis is performed for osteoarthritis, rheumatoid arthritis and post-traumatic arthritis; arthrodesis of the knee is usually performed as a last resort for infections (such as TB or neuropathic joint secondary to diabetes or syphilis), given the compromise in mobility that it causes. Technique Joints are denuded of cartilage, then shaped to conform to each other at the optimal angle; bone grafting is often used, as is some form of fixation, either internal (screws, rods, plates) or external (e.g., with a cast or external fixator). arthrodesisJoint fusion Orthopedics The creation of a bony union across a joint, which can be spontaneous or surgical; best arthrodesis joints: ankle, knee, shoulder, hip Indications Differ according to the joint; ankle arthrodesis is performed for osteoarthritis, rheumatoid arthritis, and posttraumatic arthritis; arthrodesis of the knee is usually performed as a last resort, given the compromise in mobility that it causes–eg sitting on airplanes or in movies, for infections–eg, TB or neuropathic joint 2º to DM or syphilis.

This may occur spontaneously, as a result of disease processes, or may be a deliberate surgical act done to relieve pain and improve function.arthrodesis
