====== Wrist Strain ======

A wrist strain refers to an overstretching or tearing of the muscles or tendons around the wrist joint, usually due to overuse or acute trauma.

===== Etiology =====
  * Repetitive movements (e.g., typing, lifting, racket sports)
  * Acute trauma (e.g., fall on outstretched hand)
  * Forceful twisting motions
  * Poor ergonomics during work or exercise

===== Pathophysiology =====
  * Involves microtears in the musculotendinous units
  * Inflammatory response leads to pain and limited mobility
  * May involve flexor or extensor tendons

===== Clinical Presentation =====
  * Diffuse pain around the wrist
  * Swelling and tenderness
  * Decreased range of motion
  * Weak grip strength
  * No instability (unlike ligament sprain)

===== Diagnosis =====
  * Clinical examination
  * Rule out fractures or ligament injuries with:
    * X-ray
    * MRI or ultrasound (if severe or persistent)

===== Classification (based on severity) =====
^ Grade ^ Description ^ Clinical Features ^
| I | Mild strain | Slight overstretching, minimal pain |
| II | Moderate strain | Partial tendon tear, moderate pain/swelling |
| III | Severe strain | Complete rupture, severe pain, loss of function |

===== Treatment =====

^ Phase ^ Treatment Options ^ Notes ^
| Acute (first 48–72 h) | Rest, ice, compression, elevation (RICE) \\
Immobilization if needed | NSAIDs for pain and inflammation |
| Subacute | Gentle range of motion \\
Physical therapy | Avoid re-injury, start strengthening |
| Chronic | Ergonomic correction \\
Activity modification | Consider bracing for repetitive tasks |

===== Prognosis =====
  * Excellent with early and appropriate management
  * Most resolve in 2–6 weeks
  * Risk of recurrence if not rehabilitated properly
