Musculoskeletal Disorders Flashcards
Dupuytren’s Disease
A gradual thickening and tightening of tissue under the skin in the hand that results in flexion deformities of involved digits.
OT Interventions
Wound Care- dressing, whirlpool
Edema Control- elevation
Splinting
AROM/PROM
Scar Mngmnt- massage, scar pad, compression
Interventions that emphasize gripping/releasing
Complex Regional Pain Syndrome (CRPS
Can occur in UE/LE after injury or immobilization. Pain out of proportion to initial event/injury.
Characterized by pain, sensitivity to touch, irregular blood flow, edema, changes in skin temp and color, and decreased ROM
OT Interventions
Mod to decrease pain- hot packs, TENS
AROM
Edema Mngmnt- elevation, compression
Desensitization
Stress Loading
Splinting (prevent contractures)
Avoid PROM, joint mobilization, dynamic splinting and casting
Open vs Closed Fractures
Closed fracture- bone doesn’t break skin.
Open fracture/compound fracture- bone pierces skin.
Medical treatment of fractures
Closed reduction: fixed from the outside
Stabilization: short arm cast (SAC), long arm cast (LAC), splint, sling, or fracture brace
Open Reduced Internal Fixation (ORIF): fixed from the inside. Includes nails, screws, plates, or wire
External fixation: fixed from the outside with hardware placed under the skin
Arthrodesis: fusion
Arthroplasty: joint replacement
Colles’ fracture
fracture of distal radius with dorsal displacement
Smith’s fracture
fracture of the distal radius with volar displacement
Carpal fractures
Most common carpal fractured: scaphoid (60%)
Proximal scaphoid has poor blood supply and may become necrotic
Metacarpal fractures
classified according to location (head, neck, shaft or base) common complication of rotational deformities
Proximal phalanx fractures
digits most commonly injured: thumb and index common
complication: loss of PIP A/PROM Middle phalanx fractures are uncommon
Distal phalanx fractures
most common finger fracture may result in Mallet Finger
Elbow fracture
if radial head is involved, there may be limited rotation of the forearm
Humerus fractures
Etiology: fall onto an outstretched UE
Fracture of greater tuberosity may result in rotator cuff injuries
Fracture of humeral shaft may cause injury to radial nerve, resulting in wrist drop
OT Eval of fractures
Occupational Profile, Hx
Results of special test (Xrays, MRI, CT)
Edema, Pain, Sensation
AROM Do not assess PROM or strength until ordered by MD (exception: humerus fractures which often begin with PROM or AAROM)
Roles, occupations, ADLs, activities related to roles
Phases of OT intervention with fractures
immobilization phase: goals of stabilization and healing
mobilization phase: goal is of consolidation
Immobilization phase interventions
AROM of joints above and below stabilized part
Edema control: elevation, retrograde massage, and compression garments
Light ADLs and role activities with no resistance, progress as tolerated
Mobilization phase interventions
Edema control: elevation, retrograde massage, contrast baths, compression garments
AROM: progress to PROM when approved by MD (4 to 8 weeks), exceptions: humerus fractures
Light functional/purposeful activity. Progress to occupation-based activities
Pain management: positioning and physical modalities
Strengthening: begin with isometrics when approved by MD
Cumulative Trauma Disorders (CTD)
Risk factors: repetition, static position, awkward postures, forceful exertions, vibration
Non-work risk factors: acute trauma, pregnancy, diabetes, arthritis, and wrist size and shape
Most common types: DeQuervains, Lateral and medial epicondylitis, trigger finger, nerve compressions
