Spinal fixation has different functions based on different designs, including providing support to the spine, restoring the spine to its normal condition, and providing support to intervertebral disc.
Meniscus” cartilage is a connective tissue, a three-dimensional structure consisted of water, collagen fibers, and glycoprotein, located in knee joint facet between femur and tibia.
With the change of social structure and the progression of technology, the average life span of human is extended, which leads to the increase of aged population.
Patients with degenerative joint disease have narrowed gap in knee due to worn cartilage or the gap is closed and lead to joint deformation. When the joint cartilage is worn, the bone underneath is exposed, causing friction and impact that leads to pain.
Patients often complain that they cannot straighten their fingers after bending and have to use the other hand to straighten it up. Patients can also feel a lump at the base of the side of the palm. This is the so-called trigger finger.
Spinal stenosis occurs when bone and ligament proliferates due to lumbar degenerative disease and narrows the spinal cord cavity to compress the nerves and lead to intermittent claudication or sciatica.
Spondylolisthesis occurs when vertebral body moves forward, backward, or to either side, causing the vertebral body is not aligned with the next vertebral body.
In the past, the most common treatment for bone cancer was amputation, which made patients step back from treatments. However, with the progress of various medical technologies, many types of “limb preservation surgery” are available.
“Bone cancer” refers to the malignant tumor occurs in bones, and is generally classified as primary bone cancer and metastatic bone cancer.
Intervertebral disc is a structure between the vertebral bodies in spine. Herniated intervertebral disc occurs when the outer fibrous ring ruptures due to degeneration or trauma, causing the nucleus pulpous of intervertebral disc to protrude to spinal cord cavity and compress the nerves, which leads to lower limb pain and sciatica.
