CT scanning was used to reconstruct the lumbar spine model, and then dual fluoroscopic image system (DFIS) was used to restore the lumbar facet joint movement in sitting position. Finally, the lumbar facet joint translation distance and rotation angle were measured. Results...
There are two facet joints on the back of each vertebra that connect the bones of the spine and allow for a small amount of movement. Wear and tear on facet joints in the lower spine causes the cartilage between the two bony side...
The basic anatomic unit of the lumbar spine is a three-joint complex, comprised of an intervertebral disc and paired zygapophysial (facet) joints (Fig. 31.1a鈥揷). The main function of the facet joints is to limit movement in all planes of motion with a secondary role in weight bearing....

The three-joint complex is the functional unit of the lumbar spine and comprises two consecutive vertebrae, the intervertebral disc, and the zygapophyseal (facet) joint. From: Essentials of Physical Medicine and Rehabilitation (Fourth Edition), 2020 ...
Like other joints, such as the knee joint, the lumbar facet joints permit bones to rotate. The lumbar joints are responsible for twisting, bending, and aligning thespine. Joint facet capsules also provide the lumbar facet joints with a lubricating fluid that makes movement easier. ...
The first total joint replacement for the low back. Motus Latin (mo-tus)noun A movement, motion An advance, progress Etymology: Perfect passive participle of moveō(“I move”) Replaces the function of the disc and facet joints. Allows direct decompression to address leg and back pain. ...
The synovial joints thus formed provide an excellent locking mechanism, which helps to prevent excessive rotation, as well as anterior translation (glide) movement of one segment on another. • Smooth surfaces, covered with cartilage, exist on the medial surfaces of the two superior articular ...
The changes in facet joint force at the adjacent segments. (A) The maximum facet joint force in the intact and TLIF models. (B) Changes in facet joint force with the total L1-S1 ROMs in the TLIF model. ROM: range of motion; TLIF: transforaminal lumbar interbody fusion Full size image ...
