Biomimetic lumbar artificial intervertebral disc
Spinal disease due to intervertebral disc degeneration represents a serious medical problem which affects many people worldwidedisc arthroplasty may be considered the future ‘‘gold standard’’ of back pain treatment, even if problems related to available disc prostheses are considered hence, the aim of the present study was to improve the artificial disc technology by proposing the.

The prodisc®-l total disc replacement is an artificial intervertebral disc made from metal and plastic that is used to treat pain associated with degenerative disc disease (ddd) ddd is defined as discogenic back pain (pain resulting from a degenerated intervertebral disc) with degeneration of the disc confirmed by patient history and. Study design: the biomechanical behavior of a biomimetic artificial intervertebral disc (aid) was characterized in vitro in axial compression and compared with natural disc behavior objective: to evaluate the strength and durability of a novel biomimetic aid and to demonstrate whether its axial deformation behavior is similar to that of a natural disc.
Artificial disc replacement (adr) is newer type of spinal disc procedure that utilizes an anterior (front - through the abdominal region) approach to replace a painful, arthritic, worn-out intervertebral disc of the lumbar spine with a metal and plastic prosthesis (artificial disc. The inmotion® lumbar artificial disc (depuy spine) is a modification of the charité® device with a change in name under the same premarket approval production under the name charité® was stopped in 2010. The objective of this evidence review is to determine whether artificial intervertebral disc arthroplasty improves the net health outcome compared with anterior cervical discectomy and fusion in patients who have degenerative disc disease.
Artificial total disc replacement refers to the replacement of a degenerating intervertebral disc with an artificial disc in adults with degenerative disc disease (ddd) in either the lumbar or cervical region of the spine an artificial disc is intended to preserve range of motion (rom) and reduce.

The intervertebral disc space is typically defined on an x-ray photograph as the space between adjacent vertebrae in healthy patients, this corresponds to the size of the intervertebral disc in healthy patients, this corresponds to the size of the intervertebral disc. In this thesis, a new biomimetic artificial intervertebral disc (aid) is introduced, mimicking the fiber-reinforced, osmotic, visco-elastic, and deformation properties of the ivd its concept is based on the hypothesis that the better the material structure of the ivd is mimicked, the better its functionality is mimicked. Lumbar disc arthroplasty, also known as lumbar artificial disc surgery or tda, was developed as an alternative to lumbar fusion for treatment of back pain due to severe degenerative disc disease the procedure is similar to lumbar interbody fusion, in that an anterior approach is required.
Total disc replacement, using an artificial intervertebral disc designed for the lumbar spine, is proposed as an alternative to fusion in patients with persistent and disabling degenerative disc disease.

The disc is composed of a biomimetic three-dimensional (3d) fabric with a triaxial fiber alignment that has superior mechanical properties when compared to conventional implants this disc improves on the constitutional imperfections of biological intervertebral discs by eliminating the risk of rupture and delamination. Rapid prototyping of a biomimetic lumbar artificial intervertebral disc for total disc replacement arthroplasty abstract intervertebral discs (ivds) are soft tissues that provide flexibility to the vertebral column by transmitting and distributing the large loads that act on the spine.
