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.
Osteoporosis is clinically defined as low bone quality and weakened bone tissue mechanical structure that cause bone tissues to become fragile and prone to fractures.
Current statistics indicate that males start bone mass loss later and slower than females because their bones are bigger than those in females.
After surgical removal of the tumor from the bone, high dose irradiation (20,000 – 30,000 rads) is used to kill all cancerous cells and then the bone is implanted back patient’s body for reconstruction. Such “autograft” bone reconstruction does not have concerns of cross infection, risks of hepatitis or AIDS infections, insufficient source of allograft bones, or not being able to find allograft bone match.
