Soft Tissue Disorders Lecture Powerpoint Flashcards
Soft tissue injuries are often….
….missed or undertreated, can take longer to heal than bone, can be very disabling
Principle imaging modality for soft tissue injury
MRI
Sprain
Stretch or tear of a ligament (stabilize joints connecting bone to bone so they are flexible but have an end point)
Strain
Injury of Musculotendinous unit, may impact muscle body or closer to attachment points, may impact function such as strength or range of motion
Grade 1-3 strain
1 - stretching (tenderness with active use and minimal strength loss)
2 - partial tear (clear weakness with resisted muscle and pain with passive stress)
3 - complete rupture (significant functional and strength deficits, ecchymosis, full thickness tear)
Degenerative tendon ruptures typically occur in these 2 populations
- older >40
- physically active individuals such as athletes
In tendon tear/rupture functional ability may or may not be…
…impaired - not indicative alone, depends on degree of injury
Muscle strain can either be ___ or ___
acute (sudden ecchymosis and swelling and deformity)
chronic (swelling gone away, can visualize deformity still)
Imaging studies for soft tissue injury (2)
- x ray (indirect evidence, displacement of joint or avulsed fragment)
- MRI (diagnostic, determines partial vs complete)
Treatment of muscle strain (2)
- partial, then splinting or casting
- complete, then urgent repair or reconstruction
Muscle vs tendon vs ligament tear injury recovery speed
Muscle (fastest), tendon, ligament (slowest)
Rupture vs laceration
2 examples of tendon injuries with rupture being force based and laceration being cut based
Grade 1-3 sprain
1 - stretching of ligament, good stability and no laxity
2 - partial tearing, slight laxity
3 - complete tear, no end point and severe laxity
Varus stressing tests ___collateral ligament, valgus tests ____
lateral, medial
Ulnar collateral ligament tear of the MP joint is also called….
