UE Conditions and Orthoses Flashcards
What are 4 things to consider when working with a fracture?
- Type of fx (ex. open or closed)
- Non-op or surgery
- Weight-bearing restrictions
- Associated healing time (see protocols)
List types of weight-bearing restrictions.
- Non-weight bearing (NWB)
- Toe-touch weight bearing (TTWB)
- Partial weight bearing (PWB)
- Weight bearing as tolerated (WBAT)
- Full weight bearing (FWB)
From most to least severe
What is the difference between partial weight bearing (PWB) and weight bearing as tolerated (WBAT)?
Partial weight bearing (PWB) is rather vague; it involves weight bearing but is still less than full weight bearing therefore physical limitations are still present and restrictions are still in place. Most sources define partial weight bearing as being 30% to 50% of a patient’s body weight.
Weight bearing as tolerated (WBAT) signifies that the patient is medically cleared to weight bear up to their full body weight. The patient retains the right to self-manage and pace their weight bearing activities according to their tolerance, balance, and pain levels day by day.
Describe the clinical presentation of a humerus fracture. Consider: location(s) of fx, and nerve involvement.
Humerus fx typically occur at the surgical neck/ midshaft.
The fx could effect adjacent nerves such as the radial nerve. The radial nerve innervates the muscles of the posterior arm and posterior forearm. These muscles include the extensor muscles which allow the wrist and fingers to extend.
Describe wrist drop. Which UE fracture can result in wrist drop? Why?
Wrist drop is when the wrist is unable to extend. Wrist drop is usually caused by damage to the radial nerve (radial nerve palsy). The radial nerve innervates the extensor muscles in the forearm, therefore damage to it inhibits wrist extension. The radial nerve can become damage in a humerus fracture.
When is it appropriate to use immobilization slings and a sarmiento brace?
sarmiento brace
For non-displaced humeral fractures
Describe the clinical presentation of an elbow fracture. Consider: location of fx, and nerve involvement.
Elbow fractures typically occur at the olecranon. Radial nerve may be affected.
What issue arises as a result from immobilization for an elbow fracture?
Development of contractures, specifically Volkmann’s contracture (aka compartment syndrome).
Decreased forearm ROM and wrist pronation/supination
Olecranon casting is at how many degrees of elbow flexion?
60 deg to 90 deg
List the 3 types of forearm fractures.
Type I: non-displaced
Type II: displaced
Type III: comminuted
Describe the clinical presentation of a radius fracture. Consider: location of fx, and nerve involvement.
Usually resulting from falling on an outstretched arm/hand (ext wrist).
Fracture usually occurs at distal radius. The median nerve can be affected.
What is a Colles fracture?
Falling on an extended wrist resulting in a distal radius fracture with dorsal displacement.
Which orthoses is used to temporarily immobilize a Colles fx?
Due to the dorsal displacement of the radius, a volar wrist orthosis is used.
What is a Smith’s fx?
And which nerve can be impacted?
An extraarticular fracture of the distal radius featuring a (foward or palmar =) volar displacement or angulation of the distal fragment. Usually occurs from trauma to a flexed wrist; ex. caused by a fall on the back of the hand (flexed)
Usually involves median nerve.
What is a Bennett’s fx?
Fx of the base of the first metacarpal base (base of thumb) resulting from forced abduction of the first metacarpal.
The CMC joint
Which orthoses is best for a Bennett’s fracture?
Thumb spica
What is a Boxer’s fracture?
A boxer’s fracture is a break in the neck of the 4th or 5th metacarpal bone in the hand. It usually happens when you punch an object at a high speed.
Which orthoses is best for a Boxer’s fracture?
Ulnar gutter splint
Which 2 nerves are often affected by wrist fractures?
Median and ulnar nerves
What causes carpal tunnel syndrome (CTS)?
Compression of the median nerve that runs through the carpal tunnel
M comes before U
Which digits are innervated by the median nerve?
Digits 1, 2, 3, and medial side of 4
palmar side
U comes after M
Which digits are innervated by the ulnar nerve?
Digits 4 and 5
palmar and dorsal side
Which orthosis is recommended for carpal fractures?
thumb spica
scaphoid and lunate
What is complex regional pain syndrome (CRPS)?
It is a chronic pain condition that typically affects one limb, often after an injury or trauma. The exact cause of CRPS is not well understood, and it can occur without any apparent nerve damage. Client is hypersensitive, painful, muscle weakness, edema, and/or contractures in one location despite lack of explainable cause.
What is a contraindication to treat CRPS?
No PROM exercises
What intervention should you start with if a client has CRPS?
AROM exercises
What is the purpose of a vasomotor interventions for CRPS?
Vasomotor interventions in occupational therapy aim to address the dysregulation of blood flow and autonomic nervous system function associated with CRPS. These interventions are designed to improve circulation, reduce pain, and enhance function.
Examples:
- stress loading (ex. scrubbing floors)
- desensitization / temperature biofeedback
- thermal modalities for circulation and pain
- positional changes / ROM exercises
- mirror therapy using non-affected limb
Describe the purpose of tendon excursion exercises.
Definition: Tendon excursion refers to the movement of a tendon within its surrounding sheath. It involves the gliding and sliding of the tendon as the associated muscle contracts and relaxes.
Importance: Adequate tendon excursion is crucial for normal joint movement and hand function. If tendons are restricted in their movement, it can lead to stiffness, reduced range of motion, and compromised hand function.
Define tendon excursion.
Tendon excursion = distance a tendon travels in its sheath upon movement
Tendon excursion takes place as the muscle contracts and the joint rotates. The amount of tendon excursion is related to the amount of the joint rotation. A pulley-type constraint keeps the tendon path close to the bone when the tendon crosses a joint.
excursion: how much the tendon moves from its resting position
Describe the purpose of tendon gliding exercises
- Promote smooth tendon gliding and excursion (movement).
- Improve ROM by preventing adhesions and stiffness.
- Improve finger flexibility, strength, and coordination.
What are tendon gliding exercises?
Tendon gliding exercises typically involve a series of controlled and coordinated movements of the fingers and hand. These exercises are often divided into different hand positions or finger postures.
Describe a common sequence of tendon gliding exercises, such as the “flexor tendon glide” or “Kleinert protocol”.
Involves 5 positions to make w/ your affected hand. #3 & #5 are the same
Position 1 (Full Fist): Make a full fist with the thumb on the outside.
Position 2 (Hook Fist): Bend the large knuckles while keeping the fingertips straight.
Position 3 (Straight Fist): Straighten all fingers.
Position 4 (Tabletop): Keep the wrist straight with fingers extended.
Position 5 (Straight Fist): Repeat the straight fist position.
What is the difference between Duran and Kleinert protocols?
Duran uses a blocking orthoses and PROM exercises but no AROM exercises.
Kleinert uses rubber bands for traction on the digits, AROM exercises for extension, and PROM exercises for flexion.
Calvin Klein underwear has an elastic just like the rubber band in Kleinert protocol.
