Osteoporosis is a metabolic disorder characterized by? | Reduced bone mass |
In osteoporosis, the ratio of mineral matrix is (abnormal or normal)? | Normal |
Osteoporosis: as bones lose calcium and phosphate, they become ? | Porous, brittle 'n vulnerable to frac |
What factors influence bone mass and rate of bone loss in osteoporosis? | Genetic, Estrogen, Age, Calcium intake, Exercise and general environment |
Bone mass is greater in (blacks or whites) and in (males or females). | Blacks, males |
At what stage in life will the levels of estrogen change in women? | post menopause |
At what age does the rate of bone loss begin to exceed the rate of bone formation (in other words "net loss") | Age 40 |
If calcium intake is low, where will the body find the necessary calcium? | stored calcium found in the trabeculae of the bones |
Why is exercise important in general and with regards to the onset of osteoporosis specifically? | weight bearing exercise helps increase bone mass |
What is one of the most significant environmental factors in the onset of reduced bone mass? | Smoking decreases estrogen levels = bone loss |
Compression factures of the vertebral bodies is a common complication of osteoporosis and may form what is called a __________? | dowager's hump (a rounding of the thoracic vertebrae) |
What treatments have been found to be successful in arresting osteoporosis? | None - there is no cure. Treament is aimed at prevention of future fracs |
Describe the condition: osteomyelitis. | It is an inflammation of the bone and marrow |
Adolescent hyperkyphosis is also known as? | Scheuermann's disease |
Describre Scheuermann's disease. | a growth disturbance of the epiphyseal plates anteriorly in the thoracic spine which results in hyperkyphosis |
At what age and demographic does Scheuermann's become apparent? | puberty and mostly in boys |
Scheuermann's: The child has (elevated or rounded) shoulders and (rotated or hunched) T spine. | rounded and hunched forward |
True or False: Scheuermann's is successfully treated with hormone replacement therapy. | False - the condition is self-limiting (i.e. resolves itself) |
Treatment for Scheuermann's is aimed at: | preventing progressive thoracic hyperkyphosis = postural exercises and possible a brace |
A partial avulsion of the tibial tubercle with subsequent avascular necrosis = | Osgood-Schlatter's disease |
Osgood-Schlatter's clinically presents as local pain which is aggravated by: | kneeling, climbing stairs and running |
True or False: Osgood-Schlatter's is successfully treated by surgery to the patellar tendon. | False - Osgood-Schlatters's is self-limiting |
The aim of treatment in Osgood-Schlatter's: | rest (time for healing) and stretching the quadriceps mechanism |
Fracs: a fracture occuring due to repetitive stresses = | stress or fatique fracture |
Fracs: fracture line 45' to the long axis = | Oblique fracture |
Fracs: a fracture that does not break the skin = | Simple / Closed fracture |
Fracs: tearing away of a portion of bone by forceful mm/ligament pulling = | Avulsion fracture |
Fracs: fracture of a diseased bone, the abnormal bone is weaker due to an underlying disease process = | Pathological fracture |
Fracs: one fracture segment telscopes into the other = | Impacted |
Stress frac of the 2nd & 3rd metatarsals due to repeated striking of the foot (as in marching) | March fracture |
distal fibula frac, located approx 6-7 cm above the lat maleolus - usually with disruption of distal tibiofibular lig = | Pott's fracture |
Fracs: a fracture that breaks the skin and communicates with the outside = | Compound fracture |
Bursting frac of the atlas, where ant and post arches are displaced laterally. Due to compression force applied thru top of skull = | Jefferson's fracture |
frac of distal radius with post angulation of the distal segment. Mechanise - fall on outstretched, extended hand = | Colle's fracture |
avulsion of the proximal end of the styloid process fo the 5th metatarsal = | Jone's (Dance) fracture |
frac of the distal radius with ant angulation of the distal segment. Mechanism - direct blow or fall with wrist in hyperflexion = | Smith's fracture |
Tumors: aka cancer = | Malignant |
Tumors: grow as expansile mass remaining localized to their site of origin = | Benign |
Tumors: cells that resemble the normal cells = | differentiated (benign) |
Tumors: tumors formed at locations distant from the primary tumor = | Metastases (malignant) |
Tumors: slow growing neoplasms that do not necessarily infiltrate adjacent tissues = | Benign |
What mechanism causes pain the MM's during exercise? | mm ischemia produces build up of lactic acid in extracellular fluid = pain |
Tumors: fast growing disorganized neoplasms that may infiltrate surrounding tissues = | DOMS |
Tumors: differentiated | Benign |
Tumors: lacks differentiation | Malignant |
Tumors: another name for "lacks differentiation" = | anaplasia |
Tumors: cells that resemble the normal cells = | differentiated (benign) |
What causes pain felt only hours after exercise = | mechanical damage to mm caused by eccentric mm loading - microtearing of the mm's |
What is another name for Lou Gehrig's Disease? | Amyotrophic Lateral Sclerosis |
ALS is a disease of the _______? | Motor Neurons |
ALS is characterized by a loss of motor neurons in ___? | Both the cerebral cortex and the spinal cord |
ALS is a disease of the (upper or lower) motor neurons? | Both upper and lower |
In ALS, what happens to the senory neurons? | They are not affected and thus no sensory changes are noted. Coordination and intellect also remain unaffected by ALS |
What is the typical initial complaint when ALS presents? | weakness in one of the limbs (usually the hands) |
True or False: ALS is self-limiting. | False: ALS is progressive and ultimately leads to death. |
Defective neuromuscular transmission of acetylcholine across the motor endplates of skeletal muscles = | Myasthenia Gravis |
The most common muscles affected by Myasthenia Gravis? | extraocular, facial, tongue and extremity muscles |
Myasthenia Gravis: Blocking of the binding of acetylcholine causes muscles to become? | Weak and easily fatigued |
Myasthenia Gravis is a (continuously progressive or relapsing/remitting) type of disorder. | Relapsing/remitting |
With myasthenia gravis, there is a marked absence of mm atrophy - unlike what other disease? | ALS |
A condition characterized by reactive bone formation in muscles as a result of injury? | Myositis Ossificans |
What is the usual cause of myositis ossificans? | blunt trauma to the muscl and soft tissue |
What is the best treatment for mysositis ossificans? | use R.I.C.E. to reduce blood flow to area and prevent tendency of healing cells to differentiate into bone cells. |
