First plasma was obtained on NSTX on Friday, February 12, 1999 at 7:06 p.m. . Magnetic fusion experiments use plasmas composed of one or more hydrogen isotopes.For example, in 1994, PPPL's Tokamak Fusion Test Reactor produced a world-record 10.7 megawatts of fusion power from a plasma composed of equal parts of deuterium and tritium, a fuel mix likely to be used in commercial fusion power ...
Instrumented posterior lumbar interbody fusion (iPLIF) is a common spinal fusion surgical technique for addressing low back pain resulting from degenerative lumbar spine disorders. [1] It involves fusion of two or more levels utilizing screws, rods, and an interbody graft.
Ralph Bingham Cloward (September 24, 1908 — November 13, 2000) was an American neurosurgeon, best known for his innovations in spinal neurosurgery.Cloward is known for the development of the Posterior Lumbar Interbody Fusion and Anterior Cervical Discectomy and Fusion. [1]
The FDA concluded, as part of its PMA approval process and commercial release of the TOPS System, that the TOPS group demonstrated a clinically meaningful and substantial advantage over the Fusion control group, with 77% of subjects randomized to the TOPs group achieving composite clinical success, compared to 24% of subjects randomized to the ...
Tarsal coalition is an abnormal connecting bridge of tissue between two normally-separate tarsal (foot) bones, and is considered a sort of birth defect.The term 'coalition' means a coming together of two or more entities to merge into one mass (in the case of bones, see synostosis). [1]
The Broström operation (or Broström-Gould technique) is a repair of ligaments on lateral ankle. It is designed to address ankle instability. More importantly, it is primarily used to repair the anterior talofibular ligament (ATFL) in the ankle. It is thought that the majority of patients regain most function in their ankles.
