FINAL EXAM - hints Flashcards
seronegative spondyloarthropathies are a group of disorders characterized by what 3 things?
- lack of serum markers
- HLA-B27 (human leukocyte antigen)
- inflammation of synovial joints
commonly found at DIP joints in women, hard bony swellings over joint caused by osteophytes in articular cartilage - diagnosis made using clinical information & X rays
Heberden’s nodes
(osteoarthritis)
____ arthritis is symmetrical, polyarticular arthritis & usually involves small joints
rheumatoid
chronic inflammation of tendons/ ligaments at their insertion sites which causes joint erosion, fibrosis & then ossification of joint capsule
ankylosing spondylitis
3 types of spina bifida
- spina bifida occulta: hidden, mildest, most common, one or more of SP)s fail to unite leaving open gap posteriorly
- myelomeningocele: most severe, SP’s fail to form at multiple locations (usually L-spine) & spinal canal is open exposing meninges, spinal cord, nerves & other tissues, life threatening, may cause paralysis
- meningocele: very rare, just meninges herniate, no cord involvement
difference between sprain & strain
sprain: overstretch/ tear of ligament
strain: tear of mm or tendon, commonly affecting LB, NK, hamstrings
minor stretch & tear, no joint instability on passive testing, minimal P & swelling, able to complete ADLs with minor discomfort, can weight bear, bruising absent/ slight
grade 1 sprain
partial tear of ligament, increased P, bruising & swelling, loss of function due to P, P on weight bearing, snapping sound & giving way of joint at time of injury, passive testing shows a hypermobile, but still stable joint
grade 2 sprain
complete tear, surgery required, immobilization in cast, severe injury, resulting in synovial inflammation & accumulation of synovial fluid is called joint effusion - Hemarthrosis if bleeding into a joint - Xray to rule out avulsion fracture (when bone fragment pulls away from bone by a ligament)
grade 3 sprain
few mm fibers damaged, mild P at time of injury, mild swelling, if any, minimal loss of strength, P when tissue is stressed, ADLs can be completed, heals within 3 weeks
grade 1 strain
more extensive damage to fibers or tendon, but mm not completely ruptured, snapping sound may or may not be present, can sometimes feel gap at injury site, edema, P (moderate) tenderness at site, difficulty with ADLs, loss of strength, heals 3 – 6 weeks
grade 2 strain
severe injury with complete mm rupture, snapping sound accompanies injury, severe P, edema, bruising & ADLs cannot be continued
may be joint effusion (synovial fluid accumulation) or hemarthrosis (bleeding into joint)
grade 3 strain
parallel to long axis of bone
linear
right angle to bone’s long axis
transverse
twisting of bone, causing a fracture
spiral
two or more fragments of bone from fracture
comminuted
bone/bone fragments are crushed into each other
impacted
bone is compressed as in vertebral body
compression
usually of the skull (fracture)
depression
benign bone tumors
Osteoma
Osteochondroma
Endochondroma
Osteoid osteoma
Giant cell tumour
Aneurysmal bone cyst
Fibrous dysplasia
malignant bone tumors
Osteosarcoma
Chondrosarcoma
Fibrosarcoma
Malignant fibrous histocytoma
Ewings’ sarcoma
Multiple myeloma
Polyarteritis Nodosa is strongly associate with a ____ infection
hepatitis B
highly contagious, from contaminated food or water (with feces) or from close contact with someone who is infected, no permanent damage, recover completely
hepatitis A
spreads via blood & other body fluids (sexually transmitted & with needle drugs or to baby during vaginal birth)
hepatitis B
