list 3 different tumors that affect bone: what makes them different from each other
Osteosarcoma
Osteoma
Osteochondroma
A common malignant bone tumor. Slightly more common in males or teenage boys going through rapid phases of growth. They mostly develop in long bones. It is unknown why they form. It is serious and life threatening.
Osteosarcoma
A rare benign bone tumor. Most common in the an older adult and are usually found on the head and neck. The cause is also unknown.
Osteoma
Is the most common benign tumor. They form where cartilage is found on bone. They are an extra bone growth found mostly in children.
Osteochondroma
is the degeneration of the vertebral discs. It can be caused by poor posture, heavy lifting, or a prior injury. It affects the apophyseal joints and the facet joints of the spine. Signs and symptoms are lipping, compression fractures, ligamentous thickening, and inflammation.
SPONDYLOSIS
is a slippage of one vertebral body anteriorly on another usually at L4/5 L5/S1 and causes a narrowing of the spinal canal. The cause is from a trauma with a fracture to the spine. Signs and symptoms are LBP, mm spasms, increasing lordosis, and referred pain.
SPONDYLOLISTHESIS
is a defect of pars interarticularis in the lumbar spine usually at L4/5 or L5/S1. It is seen in people who play contact sports or push gymnastics. It can be caused by a microtrauma or a genetic defect such as spina bifida occulta.
SPONDYLOLYSIS
a women’s underarms starts to swell 3 months after surgery. What is most likely the cause?
The most likely cause would be lymphedema. Lymphedema is a chronic edema resulting from an increase of lymphatic fluid. It is caused by damage or removal of the lymph nodes.
Primary cause is unknown. Secondary can be from a previous injury, infection, repetitive stress, obesity, hemophilia, or hyper-mobility. Not an inflammatory disease but does flare up at times
Osteoarthriits cause
unknown- possibly from sex hormones or a virus. It is an inflammatory disease.
RA cause
Cartilage becomes damaged creating a rough surface on the bone interfering with joint movements. The tissue damage causes enzymes to be released disintegrating cartilage further. The bone then is exposed and damage causing cysts and bone spurs. Pieces of bone can break off causing pain when moving as well as locking. The distal joints of the hands and feet are affected.
Joint changes that occur:
Osteoarthriits
Synovitis is presents which is inflammation of the joints. Deposits of immune complexes are presents. The synovium gets really thick and there is excess synovial fluid. Pannus starts degrading parts of the bone and cartilage, which leaves the bones looking chiseled out. Can become ankylosing, which is bone being built up around the joint causing the joint to become fused. It can also destroy ligaments.
Joint changes that occur: RA
Mild pain with weight bearing movements, overtime as the degeneration progresses it becomes more painful which causes more swelling and limited movements. Joints become enlarged and hard.
Signs/Symtoms: Osteoarthriits
Early on, swelling and inflammation is visible with the painful joints being red and hot to touch. Rheumatoid Factor is present. In early stages it effects the proximal joints of the hands and feet. In later stages it effects the bigger joints such as hips, knees, shoulders, elbows, C- spine, and TMJ. The pain is acute and severe. The early morning hours is where the most pain occurs taking a person one to two hours to get up and ready. Spindle fingers and muscle atrophy may be present. Joint stiffness is worse with less movement.
Signs/Symtoms: RA
PTAs we will be focusing on improving pain and function, increasing ROM, and working on strength and stabilization of the joint. Regular exercise and weight reduction should be encouraged.
