MSK Interventions Flashcards
Define decubitus ulcers
- Synonymous with pressure ulcers
Describe the grades/severity of tissue injuries
- Grade 1: mild pain & swelling and pain with tissue tensoin
- Grade 2: moderate pain & swelling requiring activity modification; tissue is focally tender to palpation; partial ligament tear may result in some increased joint laxity
- Grade 3: near-complete or complete tear with severe pain; minimal or no pain with tissue tension; palpable defect; complete ligament tear will result in joint laxity
Describe the inflammatory stage of healing
- Begins immediately and lasts 3-5 days
- Injured cells release prostaglandins & bradykinin to initiate the inflammatory response
- Platelets form a plug to contain bleeding
- Vasodilation occurs to increase blood flow to area
- Damaged tissue is removed
Describe the proliferation stage of healing
- Lasts from 48hrs to 6-8 wks
- Fibroblasts resorb collagen & synthesize new collagen
- Decreased macrophages & fibroblasts with corresponding scar formation
Describe the remodeling stage of healing
- Tissue will continue tor modal and mature for 1-2 yrs post-injury
- Increased organization of extracellular matrix
- Collagen begins to organize into randomly placed fibrils
Healing timelines for muscle
- Delayed onset muscle soreness (DOMS): 0-3 days
- Grade 1 strain: 0-4wks
- Grade 2 strain: 3-12wks
- Grade 3 strain: 4wks to 6 months
Healing timelines for tendons and ligaments
- Tendon: 8wks to 6 months
- Grade 1 ligament sprain: 0-4wks
- Grade 2 sprain: 3wks to 6 months
- Grade 3 sprain: 5wks to >1yr
Healing timeline for bone injury/fracture
- Bone: 6-12 weeks
- Cartilage (fibrocartilage): 8wks to 12 months
Define autonomic versus mechanical soft tissue/myofascial techniques
- Autonomic: stimulation of skin & superficial fascia to facilitate a decrease in muscle tension
- Mechanical: movement of skin, fascia, & muscle causes histological & mechanical changes to occur in soft tissues to produce improved mobility & function
Indications for soft tissue/myofascial techniques
- Patients with soft tissue & joint restriction that results in pain & limits ADLs
contraindications for soft tissue/myofascial techniques
- Soft tissue breakdown
- Infection
- Skin disease
- Cellulitis
- Osteomyelitis
- Contagious illness
- Malignant tumor
- Aneurysms
Describe soft tissue without motion technique
- Hands do not slide over skin instead they stay in contact with skin while hands & skin move together over the muscle
- Direction of force is parallel to muscle fibers & total stroke time should be 5-7 seconds
Describe soft tissue with passive pumping technique
- Place muscle in shortened position and with one hand place tension on muscle parallel to muscle fibers
- Other hand passively lengthens muscle and simultaneously gradually releases tension of hand in contact with muscle
Describe soft tissue with active pumping technique
- Place muscle in lengthened position and with one hand place tension on muscle perpendicular to muscle fibers
- Other hand guides limb as patient actively shortens muscle
- As muscle shortens gradually release tension of hand in contact with muscle
Describe transverse friction massage
- Used to initiate an acute inflammatory response for a tissue that is in metabolic stasis, such as tendonosis
- Performed for 5-10 minutes
- Involved tendon is briskly massaged in a transverse fashion (perpendicular to muscle fibers)
What is Feldenkrais technique
- Lymphatic drainage technique
- Facilitates development of normal movement patterns
Describe PNF hold-relax-contract technique
- Antagonist of the shortened muscle is contracted to achieve reciprocal inhibition & increased range
What are Maitland’s 4 grades of joint mobilization
- Grade I: small amplitude before the beginning of tissue resistance
- Grade II: large amplitude before the beginning of tissue resistance
- Grade III: large amplitude into tissue resistance
- Grade IV: small amplitude into tissue resistance
- Grade V: high-velocity, low amplitude thrust at the end of joint movement
Absolute contraindications in mobilizations, manipulations, & traction
- Ankyloses
- Malignancy
- Diseases that affect the integrity of ligaments
- Arterial insufficiency
- Active inflammatory and/or infectious process
Signs and symptoms of the “opioid overdose triad”
- Pinpoint pupils
- Respiratory depression
- Unconsciousness
Describe an autologous chondrocyte implantation
- Chondrocytes harvested from lesser weight bearing area of a joint
- Chondrocyte volume expanded in monolayer culture
- Re-implanted in the damaged region under a natural or synthetic membrane via an open joint procedure
- Indication: full thickness cartilage defects
- Contraindication: severe osteoarthritis
Describe platelet rich plasma therapy
- Blood collected from pt & separated into components
- Preparation of autologous plasma enriched with platelets is injected into target site
- Supplies supra physiologic amounts of essential growth factors & cytokines to provide a stimulus for tissues with low healing potential
Indications for platelet rich plasma therapy
- Tendiopathies
- Osteoarthritis
- Ulnar collateral ligament injury
- Meniscus
