Merging of a joint involves removing the joint and surgically "fusing" the joint's end so that the two bones effectively form one solid bone. This surgery stops all movement at that joint and therefore eliminates the pain. [1] The benefit of fusion is pain relief and the downside is elimination of motion at the fused joint, which can hinder ...
Spinal fusion, also called spondylodesis or spondylosyndesis, is a surgery performed by orthopaedic surgeons or neurosurgeons that joins two or more vertebrae. [1] This procedure can be performed at any level in the spine (cervical, thoracic, lumbar, or sacral) and prevents any movement between the fused vertebrae.
The surgery involves the use of screws, plates, medical nails, and other hardware to achieve bone union. [1] Ankle fusion is considered to be the gold standard for treatment of end-stage ankle arthritis. [1] It trades joint mobility for relief from pain. Ankle fusion has also been used to resolve foot drop in certain circumstances.
The field of minimally invasive surgery has spawned another set of words, such as arthroscopic or laparoscopic surgery. These take the same form as above; an arthroscope is a device which allows the inside of the joint to be seen.
Fusion welding is a generic term for welding processes that rely on melting to join materials of similar compositions and melting points. [1] Due to the high-temperature phase transitions inherent to these processes, a heat-affected zone is created in the material [ 1 ] : 755 (although some techniques, like beam welding , often minimize this ...
Joint replacement is a procedure of orthopedic surgery known also as arthroplasty, in which an arthritic or dysfunctional joint surface is replaced with an orthopedic prosthesis. Joint replacement is considered as a treatment when severe joint pain or dysfunction is not alleviated by less-invasive therapies.
Syndactyly is a condition wherein two or more digits are fused together. It occurs normally in some mammals, [1] but is an unusual condition in humans. The term is from Ancient Greek σύν (syn) 'together' and δάκτυλος (daktulos) 'finger'.
Synostosis (from Ancient Greek συν- (syn-) 'together' and ὀστέον (ostéon) 'bone'; plural: synostoses) is fusion of two or more bones. It can be normal in puberty (e.g. fusion of the epiphyseal plate to become the epiphyseal line), or abnormal. When synostosis is abnormal it is a type of dysostosis. Examples of synostoses include:
