Thursday 9th May Test Flashcards
Cardinal signs of Inflammation
Heat, redness, pain, loss of function, swelling
Scar tissue causes
Inflammatory response, prolonged immobilization, paralysis or paresis
Four types of scar tissue
Contracture, adhesions, irreversible, contracture, proud flesh
What is contracture?
Shortening of connective tissue over or around joint
What is adhesions?
decreased ROM in a jt allows cross-links to form amongst collagen fibres
What is an irreversible contracture?
Permanent loss of range of motion which occurs as a result of fibrous tissue or bone replaces muscle or connective tissue
What is proud flesh?
Thickened dermal granulation tissue due to abnormal healing
What is one contraindication for scar tissue?
No friction on anti-inflammatories
Frictions not recommended for proud flesh or keloids
What are the different types of wounds?
Abrasion, laceration, incision, puncture, avulsion
What is an abrasion?
An abrasion is a scrape or superficial wound
What is a laceration?
Laceration is a jagged, cut and increased tissue loss
What is an incision?
An incision is a precise cut with an instrument like a scalpel
What is a puncture?
A puncture is a hole with clean edges and a small entry point
What is an avulsion?
And avulsion is a partial or complete tearing of skin and underlying tissues
What are two causes of burns
Thermal and chemical burns
What is a thermal burn?
Open flame source
Scalding from hot liquid
Cold from frostbite
What is a chemical burn?
Acids or alkaline
Must be cleaned and deactivated to prevent further injury
Secondary injuries could occur
Can be very toxic
Organ failure
Two complications of burns
Breathing (thoracic burns, can interfere in lung expansion and can increase risk of pathologies such as pneumonia)
Inhalation injury (inhalation of heated air or obnoxious chemicals, respiratory failure can result up to two days post accident)
Contusion versus haematoma
A contusion is a crush injury to a muscle damaging muscle fibers, resulting in bleeding into subcutaneous tissue and skin
A haematoma is a large area of local hemorrhage, following a trauma, pooling of blood causes pain, swelling, and compresses, nearby nerve endings
Define strains and two causes
An overstretched injury to the musculotendinous unit
Sudden overstretching of muscle and extreme contraction against resistance
Definition and cause of sprains
An overstretched injury to a ligament
A sudden twist or wrench of joint past its normal range of motion
One contraindication of sprains
In acute stage, testing, other than pain-free active range of motion is contraindicated to prevent further tissue damage
Avoid removing the protective muscle splinting of acute sprains
Causes of cruciate injuries
ACL - blow to lateral knee
Blow to posterior knee
PCL - blow to anterior tibialis
Excessive hyperextension
Causes of meniscal injuries
Twisting of knee while foot is bearing weight and anchored to ground
