Chapter 8: Sprain Flashcards
An overstretch injury to a ligament is called:
Sprains
Composed of flexible, non contractile connective tissue. Occur in bands around a synovial joint, blending into the periosteum and joining bones together. This is called:
Ligaments
What are the causes of sprain?
Trauma - related sudden twist or wrench of the joint beyond its normal range of motion.
What are the contributing factors of Sprain?
- Congenital ligamentous laxity ( hypermobility )
- History of previous sprains
- Altered biomechanics ( rheumatoid arthritis )
Sprain is classified into three level of severity. includes:
Grade 1, mild or First degree
Grade 2, moderate or second degree
Grade 3, severe or Third degree
Level of severity where there is a minor stretch and tear to the ligament.
Mild or First degree
Level of severity where there is tearing of the ligament fibres occurs.
Moderate or Second degree
Level of severity where there either a complete rupture of the ligament itself.
Severe or Third degree
True or False:
Pain is present in acute stage, while a chronic sprain may be painlessly hypermobile in the direction the ligament is intended to check.
True
Condition that occur when the injury is severe enough to inflame the synovium, increasing the production of synovial fluid and causing the joint capsule to swell.
Joint Effusion
What are the 3 types of cartilage in the human body?
a) Hyaline
b) Fibrocartilage
c) Elastic cartilage
True or False:
Cartilage is essentially avascular and aneural; therefore has a slow and difficult repair.
True
It is the second most commonly sprained lateral ankle ligament, often injured in conjunction with the anterior talofibular ligament.
Calcaneofibular ligament
A condition decribes when a joint is positioned beyond its normal range, injuring (tearing) the ligaments and often the joint capsule.
Sprain
What are the Percentage of fibres torn in first and second degree?
First degree: 0-20% Second degree: 20-75%
