soft tissue injury Flashcards
articular joint pain
gout, RA, OA, bone
- Relate to joint structure, pain at joint line when palpate
- Pain on both active and passive movement
non articular joint pain
□ Ligaments, tendons, muscles
□ Features:
* On palpation: paint near joint, (maximal tenderness)
* Pain on active movement > passive
* Pain maximal at certain lines of muscle pull
causes of articular joint pain
1) visceral pain (pancreatitis, gallstone, kidney, UTI)
2) tissue pain (DVT, ischemia, infection)
3) neuropathic pain (nerves, prolapsed intervertebral disc)
4) bone pain (fracture, trauma)
features of soft tissue injury (self-limiting)
□ Consequences of chronic repetitive low-grade trauma/ overuse
- Microtear, microinflamm (may not be visible to eye)
□ Focal and non-systemic (can point to location)
□ Self-limiting (can heal by itself)
□ Conversative measures (RICE, supportive)
urgent referral for soft tissue injury
□ Fractures
□ Ligament rupture
□ Infection-related causes (prevent sepsis, spread of damage)
□ Malignancy/ metastasis (lower back pain, esp for prior hx)
□ Relate to underlying visceral conditions (lower back pain)
tx management
1) non pharm RICE
2) pain relief (TOP -> PO NSAIDS/ paracetamol, CS)
* avoid opioids
tx goal
- reduce pain
- reduce freq
- prevent future injury
types of non-articular soft tissue injury
- ligament
- tendon
- bursae
- fascia
- muscle
sprain pathophysiology
- ligament (Bone-bone connective tissue)
- stretch/ partial/ complete rupture
- ***anterior talofibular ligament
(may affect 1st, 2nd ligaments which cause significant ankle instability)
features of sprain
○ Sudden onset of pain and swell after POP sound
○ Swell, tenderness
○ II, III: ecchymosis (bruise)
○ III: cannot bear weight or ambulate (loss of motion and function, unable to limp)
cause of sprain
- sport
- inversion of foot (land on the outer part of feet)
- child, adol > adults
- F > M
tx of sprain
- protect
- rice
- PO pharmacotherpay
III: refer to ER
tendonitis pathophysiology
tendon connects bone and muscle
inflammation, irritation
tendinopathy disease progression
(tendonitis / inflam–> rupture –> tendinosis/ degen)
features of tendonitis
- Local pain
- Dysfunction
- Inflamm –> Degeneration
- Pain in particular direction and pull (When tendon stretched )
common sites of tendonitis
- Shoulder: rotator cuff tendinopathy
- Elbow
○ Outside: Tennis
○ Inside: Golfer’s - Wrist
○ Flexor carpi radialis/ ulnaris tendinitis - Hip (lateral)
○ Gluteus medius/ minimus tendinopathy - Ankle
○ Achilles tendinopathy (jumping sports/ running over hilly terrain)
tendonitis causes
- Overuse, overload
- Sports injury
- Inflamm rheumatic disease
○ FH, PMH, recurrence - Ca apatite deposition (metabolic disturbances)
- Drug induced — FQ, statins (myalgia)
bursitis pathophysiology
inflamm of bursae (Fluid-filled sacs around joints that cushions tendons/ muscles from adj bones)
Lined by synovial mem in clefts b. mobile structures
- Pain occurs when motion compresses adj bursa to point where intrabursal P. icnr
