Chapter 43 Flashcards
Explain a contusion/bruise
Results from direct trauma, skin is intact, blood/cell damage
What is a hematoma?
Blood accumulation, localized
What is a strain?
Partial tear of the muscle/tendon
Risk of strain?
Increased age (fibres less elastic)
Manifestation of strains?
Pain, stiffness, swelling, tenderness (usually no sign unless inflammation)
What is a sprain?
Tearing/ rupture of supporting ligament (bone-bone) due to abnormal/excess joint movement
Can you detect sprains on x-ray?
No- unless bone fragments
Manifestation of sprains?
Pain, swelling (limits movement), discoloration
Treatment of strains/ sprains
RICE
C- give support, reduces swelling
In sprain healing, what do capillaries do? fibroblasts?
Capillaries bring oxygen/ nutrients
Fibroblast produce collagen (collagen bundles strengthen over time)
What are complications in sprain healing?
contraction can pull healing apart and result in lengthened position, adhesions
What are dislocations? What is a subtype of a dislocation?
Abnormal displacement of two joining (articulating) surfaces
Subluxation (partial dislocation)
What are common joints for dislocations?
Shoulder, Acromioclaviular, glenohumeral
What are the 3 types of dislocations?
- Congenital (hip or knee)
- Traumatic (MVA, hip, shoulder, knee, wrist, ankle)
- Pathologic (complication of infection, rheumatoid arthritis, neuromuscular disease)
How can you diagnosis dislocations?
History, assessments, x-rays
Manifestations of dislocations?
Pain, deformity, limited movement
What is the treatment of dislocations?
Spontaneous, manipulation, surgery, physiotherapy
What three bones does the shoulder include?
Clavicle, humerus, scapula
What is the function of the rotator cuff?
Stabilizes the humeral head against the glenoid
T/F: Shoulder joints are stable?
False
What do rotator cuff injuries result from?
Direct blow or stretch, excessive use, increasing age
What are common conditions associated with rotator cuff injuries?
Tendinitis, Subacromial bursitis, partial/complete tears
Manifestations of rotator cuff injuries?
Pain, tenderness, difficulty moving arm, muscle atrophy, inflammation
How are shoulder/rotator cuff injuries diagnosed and treated?
Assessment of active/passive ROM, history is important, MRI, Arthroscopic exam
Anti-inflammatories, corticosteroids, physiotherapy, surgery
Knee Ligamentous injuries are the most serious. What is the cause of them? and what are the manifestations?
Forceful stress or pop
Swollen due to hemorrhage, pain, inability to weight bear
Knee meniscus injuries result from sudden rotation. What are the manifestations and complications?
Pain, edema, instability, locking d/t loose fragments
osteoarthritic changes limiting movement
Knee patellar subluxation & dislocation is partial dislocation of the knee cap usually sports related. What are some manifestations?
Weakness, swelling, crepitus (cracking, grating), stiffness, loss of ROM
Knee patellofemoral pain syndrome is the most common cause of anterior knee pain. What are the causes? and manifestation?
Imbalance of force controlling patellar, contact with femur, running, jumping, sitting
Pain, weakness, absence of edema
What is chondromalacia and its causes? *
Inflammation of the underside of the patella
Sports, knee overuse in older adults
Treatment is RICE, anti-inflammatories, physio
What is the cause of a hip injury dislocation? What is there a disruption in?
Trauma
Blood and nerve supply- a complication of this is avascular necrosis***
What are risk factors for hip fractures?
Age, woman, inactivity, alcohol excess, pyychotropic medications, institutionalization, visual impairments, polypharmacy, osteoporosis
