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 ...
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 ...
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.
When the structures outside the joint are affected, the term "false ankylosis" has been used in contradistinction to "true ankylosis", in which the disease is within the joint. When inflammation has caused the joint-ends of the bones to be fused together, the ankylosis is termed osseous or complete and is an instance of synostosis. Excision of ...
The bonded surface has the same physical and mechanical properties as the base material. Once bonding is complete, the joint may be tested using tensile testing for example. The diffusion bonding process is able to produce high quality joints where no discontinuity or porosity exists in the interface. [13]
Nuttall mentions Shine in the U.S. and Astral Systems in the U.K. as two firms at or near commercial readiness to apply fusion technology to medicine and other industries.
Arthroplasty (literally "[re-]forming of joint") is an orthopedic surgical procedure where the articular surface of a musculoskeletal joint is replaced, remodeled, or realigned by osteotomy or some other procedure. It is an elective procedure that is done to relieve pain and restore function to the joint after damage by arthritis or some other ...
Five types [4] of syndactyly have been identified in humans. The corresponding loci associated with these types and their common phenotypical expression are as follows: . type I: 2q34-q36; [5] webbing occurs between middle and ring fingers and/or second and third toes.
