Overview
Dislocations and soft-tissue injuries represent the most common musculoskeletal emergencies in clinical practice. Mastering these topics is essential for understanding the biomechanics of joint failure and the systematic management of acute trauma patients, making it a high-frequency area for both theory and clinical viva exams.
Joint Dislocations
A dislocation is the complete disruption of articulating surfaces of a joint, usually resulting from high-energy trauma. Exam focus lies on recognizing clinical deformities and understanding the neurovascular structures at risk during reduction.
- Shoulder: Most common, usually anterior dislocation
- Hip: Posterior dislocation is most common, risks avascular necrosis
- Elbow: Often associated with ulnar nerve injury
- Clinical triad: Deformity, loss of function, and pain
- Reduction priority: Restore alignment to prevent vessel compression
Sprains and Strains
Sprains involve the stretching or tearing of ligaments, while strains involve injury to muscles or tendons. Understanding the classification grades is crucial for determining treatment protocols.
- Grade I: Microscopic tearing, minimal pain
- Grade II: Partial tear, moderate functional loss
- Grade III: Complete rupture, severe instability
- RICE protocol: Rest, Ice, Compression, Elevation
- Common sites: Ankle (ATFL) and Knee (ACL)
Tendinitis and Overuse Injuries
Tendinitis is the inflammation of a tendon caused by repetitive microtrauma rather than a single acute event. These are chronic conditions that require long-term conservative management strategies.
- Common examples: Tennis Elbow (Lateral Epicondylitis)
- Golfer's Elbow: Medial Epicondylitis
- Achilles tendinitis: Often seen in athletes
- Pathology: Failed healing response of collagen
- Treatment focus: Eccentric strengthening exercises
Exam Tip
Always link a dislocation to its most common associated neurovascular complication (e.g., shoulder dislocation with axillary nerve injury) to guarantee maximum marks in viva and theory.
Common Mistakes
- Confusing sprains (ligaments) with strains (muscles/tendons) in short-answer definitions
- Failing to mention neurovascular assessment, which is critical in all dislocation management
- Ignoring the Grade I-III classification system when describing ligamentous injuries
