1. Musculoskeletal - Introduction Flashcards
Ligament
Connects bone to bone; weakest at ends
Tendon
Connects muscle to bone
Bursa
Fluid filled sac in between tendon and bone that reduces friction
Fascia
Fribrous membrane that covers, supports, and separates muscles
Synovial capsule
sac-like structure enclosing bone ends, present at almost every joint
Periosteum
Fibrous membrane that covers bone except at bone ends
Intra-articular cartilage
dense connective tissue that acts as a shock absorber between bones inside the joint capsule (i.e. meniscus in knee)
Edema
edema within connective tissue or OUTSIDE the joint capsule
Effusion
edema INSIDE the joint capsule
Hemarthrosis
Blood in the joint
Ecchymosis
Bruise
Crepitus
crackling from inflammation or fractured bone ends
Symptom
subjective complaint by patient
Sign
Objective observation by provider
Acute
Sudden onset of symptoms within a short duration (sprain, fracture)
Chronic
Gradual onset of symptoms with longer duration, usually >2-3 weeks
sPrain
Stretch/tear of a LIGAMENT or CAPSULE; 3 degrees-stretching; incomplete tearing & rupturing
sTrain
Stretch or tear of TENDON or MUSCLE
Tendinitis
Inflammation of tendon
Tenosynovitis
Inflammation of tendon and synovium
Arthritis
Inflammation of a joint
Bursitis
Inflammation of a bursa
Fasciitis
Inflammation of fascia
Osteomyelitis
Infection of a bone
Fracture
Breaking of a bone
Dislocation
Movement of a bone from its natural position that has to be reduced; 80% CHANCE OF RECURRENCE; Most common joints = fingers, shoulder, patella
Subluxation
Same as dislocation but it returns to original position on its own; partial dislocation
Osteomalacia
Softening of the bone
Osteoporosis
Weakening of the bone
Kyphosis
Rounding of the thoracic curve; hump back
Lordosis
Exaggerated lumbar curve; sway back
Scoliosis
Lateral curvature of the spine
SponDYLOsis
DEGENERATION of vertebra
SponDYLOLYsis
Defect in vertebra (“Scottie dog fracture”)
SpondylOLITHEsis
Anterior slippage or subluxation of vertebra (“Scottie dog decapitated”
Coronal plane
front to back
Frontal plane
front to back
Transverse plane
Top to bottom
Horizontal plane
Top to bottom
Sagittal plane
Right to left
Concentric resistance
Resistance during shortening of muscle
Eccentric resistance
Resistance with lengthening of muscle
Isometric
Muscle contraction without joint movement
Grade 0 (zero)
No muscular contraction
Grade 1 (trace)
Slight contractility, no motion
Grade 2- (poor -)
Initiates movement if gravity eliminated
Grade 2 (poor)
Complete RoM w/o gravity
Grade 2+ (poor +)
Initiates RoM against gravity
Grade 3- (fair -)
Some RoM against gravity
Grade 3 (fair)
Complete RoM against gravity
Grade 3+ (fair +)
Complete RoM against gravity w/ min resistance
Grade 4 (good)
Complete RoM against gravity w/ moderate resistance
Grade 5 (normal)
Complete RoM against gravity w/ max resistance
Palpation
Intelligent laying of hands to feel bony and soft tissue landmarks to elicit a subjective response from patient
When to use orthopedic tests
Used to substantiate diagnosis, not to diagnose; should back u pwhat you think is occuring from history
When to use neuro tests
To assess peripheral nerve damage, spinal nerve root damage, spinal cord damage
Neuro tests used in Ortho
DTRs, sensation testing, sharp/dull discrimination; vibratory
