- Meshed graft has a waffle like appearance
18
Q
Know about nutritional needs of burn survivors
A
- Patients need 3 times the normal protein intake
- No free water- you need them to take in as many calories as they can
- Eschar – protein secreted through hair follicles that need to be removed
19
Q
ROM
A
- ROM should be performed every day – contractures can form in 1-3 days
- Patients may require several sessions due to fatigue or more involved areas will need 2 times a day (common with hand burns)
- It’s best if performed during the bathing procedure when bandages are removed
- ROM is usually extremely painful. It’s a learned skill of knowing what needs to be pushed to gain movement and what may be detrimental
- Pain control is a team effort
20
Q
When to Perform AROM
A
- As soon as the patient is alert
- Helps with strengthening
- Gives patient control over their care
- Provides them with activities they can do on their own when therapist is not available
21
Q
When to perform AAROM
A
- AAROM can be performed by patient or therapist
- If patient is alert, AAROM can be by their own body or an object i.e. wall (wall slides, pulleys)
- The therapist can help when the patient cannot complete the arc of motion due to pain, weakness or fatigue
22
Q
When to perform PROm
A
- When the patient is not alert
- This can include under anesthesia, patients given paralytics
- Caution must be used to not damage structures i.e. joints since the patient cannot respond to pain
23
Q

26
Precautions with ROM and exercise: other
• Medical equipment
• Exposed tendons
• New autograft sites or unstable/fragile autograft sites
• Neuropathies
• IVs
• Exposed joints
• Associated injuries
• Cellulitis
• Heterotopic ossifications – a sudden dramatic decrease in ROM with specific joint pain, only perform AROM until surgically removed
• Escharotomy – an incision with a scalpel through eschar down to subcutaneous tissue, continue ROM but without dressings to view any signs of wound stress, no ambulation if on legs
Fasciotomy
27
Pressure garments : function
* Control hypertrophic scarring
* Promotes healing
* Assists with venous return
28
Indications for pressure therapy
* 2nd or 3rd degree burns
* Can initiate with minimal open areas (can still have bandages on)
* Measure for custom garments after temporary compression has been used
* Garments are worn 23 ½ hours a day until scars are mature
29
Types of temory compression
Ace wraps ■ Compressogrip/tubigrip
Support hose ■ Foam neck collars
Coban ■ Isotoner gloves
30
Types of custom compression
* Nylon/spandex blend of material with 25-30 mmHg of pressure graded into the garment
* Increase pressures are available for special needs
* Garment details – fit, inserts (foam, otoform, silicone)
* Features – zippers, velcro, linings, soft/regular/heavy material, contracture seams
* Garments must be worn 23 ½ hours a day
* Inserts can be placed in the garments to provide a better fit
31
Complications and progression: Mature scar
o Fades to approx normal skin color
o Soft in texture with an elastic quality
o Scars remain active for several months to a year or longer
32
Complications and progression: immature scar
o Hyperemic (erythema) – red to purple in color indicating increased vascularization
o Pruritis – itching
o Decreased pliability – not supple, unyielding
o Hypertrophic – excessive production or collagen fibers that assumes a disorganized orientation producing a raised irregular appearance and inelastic quality
o Keloid – hypertrophic scar that has exceeded beyond the borders of the original scar
33
Complications and progression: Blisters
Inadequate pressure – most often on donor sites
Bumping or shearing
Resistance without compression
Infection – look for redness, pustules, pus
34
Rash
o Can be caused by:
Continued use of medication when healed
Overuse of oily lotions (Elta)
Detergent reactions
35
Shearing/Bumping
o Educate patient about skin frailty
| o If occurs patient can apply bandaid or dressing with ointment to keep moist
36
Dry Scabs
o Encourage to keep dressings on until healed
| o Scabs slow healing and increase scarring
37
Hypertrophic scarring
o Increase pressure, increase scar massage and silicone use
38
Thermal
* Types: flame, scalding, thermal contact
* Temperature causes direct damage to the skin and sometimes the underlying tissue
* Thermal common with children and elderly – watch patterns for abuse
* Flame patterns vary and may involve inhalation in enclosed areas
39
Chemical
caused by an acid, alkali, or organic compound
• Severity depends on the agent, concentration volume and duration of exposure
• Sporadic pattern
• Know the chemical to neutralize burning process
40
Electrical
* Caused by contact with high voltage or low voltage electricity or lightning strike
* High voltage (power lines) causes underlying injury as well as obvious tissue damage
* Low voltage (household) causes minimal cutaneous damage plus pain and neurologic sequelae
* Lightning may cause cardiac arrest and other injuries
* “Tip of Iceberg” entrance small, exit is blowout
41
Radiation
* Damage due to radiant energy such as nuclear explosions or contact with radioactive materials
* Sunburn (ultraviolet)
42
first degree
superficial, erythema (red), no blister, sensitive, spontaneous healing (epidermis)
43
Second Degree
superficial partial thickness or deep partial thickness, erythema, blister, painful, wet, edema, re-epithelializes in 14-20 days (at the dermal layer)
o Can go deeper
44
Third Degree
Full thickness, white brown/charred, leather appearance, NO blisters, insensate, affected areas depressed, produces granulation tissue, will need grafting. Can heal in months/ years but with increased chance of infection (in the fat or the muscle)- not in pain
45
Fourth Degree
Involvement of muscle, tendon, bone and fascia or exposure of deeper structures
o Will often require local or distant tissue flaps for reconstruction – skin grafts must have a good bed for survival
o Often requires amputation of involved extremity or digit
46
Meshed Graft
stretched- it’s very nice and covers a larger part- it leaves a pattern- leaves a waffle pattern
o Can tear easier and it is easier to use
47
Full Thickness
full includes
o The debridement takes a lot of subcutaneous tissue and blood flow to it (has to be in the general vicinity) - have to replace this- not just skin
48
what to do if it's a chemical burn
- How to neutralize it and what happened
49
Post-OP

72
- Non-Thermal or Mechanical Ultrasound: Facilitates wound healing
o through destabilization of cellular membrane through ion diffusion and subsequent increase in phagocytic activity and eventually enhanced protein synthesis
o can be used to decrease inflammation in both acute and chronic inflammatory conditions with low intensity
73
- Continuous ultrasound: used for thermal (heating) effect
o used for 5-8 or more minutes
o can be used for healing scar tissue
o heating joint capsules, ligaments, and tendons to loosen adhesions

What is an FCE
- Functional Capacity Evaluation (FCE) is an objective and comprehensive assessment of an individual’s physical and functional abilities.
80
Why should we perform an FCE?
Determine if an individual can do their job safely for 8 hours a day
Determine an individuals effort - or lack of
Provide objective documentation for a physician’s restrictions
Provide objective documentation of abilities for vocational rehabilitation or impairment/disability determination
Determine need for further rehabilitation (ie progression to work conditioning)
81
Functional activities are terminated and these are correlated with objective physiologic signs to include
Change in body mechanics
Accessory muscle recruitment, substitution patterns
Fatigue pattern, tremoring, shaking
Increased heart rate and blood pressure
Research shows a direct relationship between size of active muscle mass and the magnitude of HR increases. (Seals et al)
82
What is Wadell's testing?
- A non-organic sign presented is a positive finding
- One non-organic sign in isolation may be present with some organic conditions and should be discounted
- Three or more non-organic signs is the criterion for a Positive Waddell’s Non-Organic Signs Test
- A positive non-organic sign should alert the clinician to the need for more comprehensive testing
83
- Superficial Tenderness
o Tender to light touch over a wide area of lumbar skin
84
Non-anatomic Tenderness
o Deep tenderness is felt over a wide area, is not localized to one structure, and often extends to the thoracic spine, sacrum or pelvis
85
Axial Loading
o Vertical pressure (1-2 lbs) over the skull while the patient is standing
o reproduces low back pain
86
Rotation
o Back pain is reported when the shoulders and pelvis are passively rotated in the same plane.
o In the presence of root irritation, leg pain may be a normal response
87
Weakness
formal strength testing reveals a partial cogwheel effect of "giving way"
88
Sensory
o Sensory testing reveals a diminished sensation in a stocking rather than a dermatomal distribution. Use caution when testing patients with a spinal stenosis of s/p root multiple spinal surgeries. Multiple nerve root involvement can mimic a regional disturbance.
89
Over-Reaction
o Over-reaction may take the form of disproportionate verbalization, facial expression, muscle tension, tremor, collapsing, or sweating
- Use caution against observer bias
- Recognize that there are considerable cultural variations
90
What does ORIF stand for?
- Open Reduction Internal Fixation
91
What does TFCC stand for?
- Triangular fibrocartilage-The disc. Like a meniscus in the knee
- Triangular fibrocartilage complex-The ligamentous borders, ECU
- and its sheath as well as the disc
Symptoms:
- supination and pronation
92
What is ulnar abutment
- Ulnar sided wrist pain
- Pain with supination (ulna migrates distally with supination. If a positive variance exists then more pressure on TFCC and carpals)
- Pain with weight beating and power grip secondary to change in load
- Normally a 22 degree incline between ulna and radius. Weight is distributed approximately 80% radius and 20% ulna.
93
What is skiers thumb and how do we treat it? What is injured?
- Ulnar Collateral Ligament Injury:
- Conservative Treatment:
o Activity Modification
o Splint wear- 6 to 8 weeks
o NSAIDs
o Modalities as needed
- Surgical Intervention:
o Repair ligament with pin or screw
o Thumb spica cast
o Thermoplastic splint
o 6 to 8 weeks immobilization
94
Scaphoid Fractures facts
- fractures are the second most common wrist injury & most commonly fractured carpal bone.
- 60-80% of carpal fractures involve this bone.
- Forearm & thumb will have a thumb spica cast with IP free for 6 to 8 weeks.
- Wrist immobilization with slight palmar flexion and radial deviation.
- Splinting after cast removal is common.
- Feels like a sprain.
- Unlike the forearm, hand, and finger bones, fractures of the scaphoid rarely show any obvious deformity.
- Diagnosis delayed for weeks, months or even years
- The fracture may occasionally be invisible on the first x-ray, only to show up on an x-ray taken weeks or months later when bone re-absorption at the fracture site occurs
95
Symptoms of scaphoid fractures
- Common presentation is pain in snuffbox
- Limited ROM due to pain (extension /RD)
- Decreased grip strength
- Painful grip and pinch
96
Healing time for scaphoid
o Expected time to union for acute fractures is 6-24 weeks:
o (1) Distal third = 6-8 weeks
o (2) Middle third = 8-12 weeks
o (3) Proximal third = 12-24 weeks
-- Proximal Pole fractures don’t heal well secondary to retrograde blood flow. These fractures must undergo ORIF of either screw or pinning and might require a bone graft.
97
- Therapy for Scaphoid Fx
o A cast or splint is worn during fracture healing (6 to 8 weeks unless ORIF performed then they can move sooner)
o Encourage movement of digits & proximal joints, not
o thumb
o Avoid heavy lifting, gripping, contact sports, & activities such as climbing ladders
o Initially in therapy the goal is to control the pain &
o edema
98
