Answer: Inflammation of tendons usually from repetitive strain or overuse; common sites: rotator cuff, Achilles tendon, patellar tendon, lateral epicondyle.
- A A localized bacterial infection that gradually spreads throughout the protective fibrous sheath surrounding a particular tendon
- B Inflammation of tendons usually from repetitive strain or overuse; common sites: rotator cuff, Achilles tendon, patellar tendon, lateral epicondyle
- C A slow, chronic degenerative disease process that specifically and primarily affects the long bones found within the limb
- D Inflammation that occurs specifically and only within the fibrous ligaments themselves, rather than within the tendons connecting muscle to bone
Correct answer: B. Inflammation of tendons usually from repetitive strain or overuse; common sites: rotator cuff, Achilles tendon, patellar tendon, lateral epicondyle
Explanation: Tendinitis is inflammation of a tendon, usually from repetitive motion, overuse, or sudden injury. Common examples: rotator cuff tendinitis (shoulder), Achilles tendinitis (heel), tennis elbow (lateral epicondylitis - extensor tendons). Symptoms: pain, swelling, reduced movement. Treatment: rest, ice, physiotherapy, NSAIDs.
