Orthotics Flashcards
What is an orthosis?
Rigid/semi-rigid device used for support, alignment, prevention/correction, improve function & restrict motion
What are L-codes used for?
- Billing & coding
- Not always recognized by insurance carriers
- Reimbursement rates differ
What are the categories of MCOS?
Modified Orthosis classification system (MCOS)
- Articular (does cross jt)→ shoulder, elbow, wrist, foot,
- Non-articular (doesn’t cross jt)→ humerus, forearm, metacarpal, phalanx
What are some design descriptor words used?
- digit based
- hand based
- thumb based
- forearm based
- arm based
- circumferential
- gutter
- radial
- ulnar
- dorsal
- volar
- anterior
- posterior
What is a static orthoses?
immobilizes/blocks joint & allows mvmt at another
elongates
What is a serial static orthoses?
applied with tissues at max length; accommodate soft tissue elongation
→ circumferential; worn for long periods of time
What is a dynamic orthoses?
static base with mobilizing attachments
- rubber bands
- springs
- neoprene
- elastic cord
flexible
What is static progressive orthoses?
Low load force to tissue’s max end range until tissues accommodate; no further stress to tissues
* nylon cord
* strapping
* turnbuckles
**similar to dynamic splints
What are common objectives for immobilization splints?
- system relief AFTER injury/overuse
- protection
- position of edematous structures
- max functional hand use
- maintain tissue length→ prevent contracture
- JT alignment
- Block/transfer power of mvmmt
- reduce tone and/or contracture of spastic M
articular & non articular
What are common objectives for mobilization splints?
- remodeling
- elongation of soft tissue/contractures/adhesions/musculotendinous tightness
- ↑ PROM
- realign jt
- substitute for weakness/absent motion
- maintain fracture reduction
- provide resistance for therex
What are some considerations for mobilization splints?
- age
- motivation
- psychological status
- associated trauma/disease
- advocational/vocational demands
- quality f joint ROM & end feel
- A/PROM
- time since injury/ repair
What are some common objectives for restriction splints?
- limit motion after nerve/tendon injury & repair
- limit motion after bone-ligament injury repair
- provide & improve jt stability & alignment
- assist in functional hand use
What is the significance of bony prominences for fabricating?
- considered when fabricating orthoses
- vulnerable areas (min soft tissue covering)
- avoid pressure over these areas (material/strapping)
- pt education is important→ skins checks & avoid pressure sores
What are warning signs to bony prominences?
pain, redness and skin breakdown
What are some symptoms of nerve compression?
- burning
- itching
- numbness
- tingling
- paresthesia
- motor control changes
What can the cause of compromised circulation be due to?
- medical history
- splint material
- strapping
What are signs of impaired circulation?
- color changes
- throbbing
- temperature changes
What are the stages of wound healing?
- Inflammatory stage→ fragile ting (early)
- Fibroplasia (Proliferative) stage → mobilzation (later stages)
- maturation (remodeling) stage→ mobilization & restriction
What are some factors that affect wound healing?
- age
- nutrition
- tobacco use
- alcohol use
- medical conditions
- edema
- steroids
- radiation therapy
- infection
