Q

Distal Radius Fractures

A

One of the most common fractures in adults & usually from a fall on an outstretched hand (FOOSH)

Often associated with co-occurring injury

Radial fractures can cause shortening of the bone which can lead to ulnar abutment syndrome

Q

Colles fractures- Fracture of the distal radius with DORSAL angulation

A

Surgical goal restore radial length and joint alignment to avoid ulnar abutment syndrome (compression of TFCC)

If fracture crosses the distal radial ulnar joint (DRUJ) or has involvement of the ulna then supination, pronation and radial/ulnar deviation will be affected

Q

Articular fractures involve the joint surface and usually require

A

external fixation to re-establish normal anatomical surfaces and alignment. If the joint surfaces are not preserved this will lead to pain, limitations in motion and arthritis from wear and tear.

Q

Positive for ulnar variance

A

the TFCC gets pinched- this creates ulnar sided wrist pain- supination makes it worse or if you add grip (shoves the ulna even farther in there)
- increases the load on the ulna

Q

Ulnar Abutment Syndrome

A

-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.

Q

Management of carpal fractures

A

Carpal fractures are considerably less common than distal radius fractures.

Scaphoid fractures are the second most common wrist injury & most commonly fractured carpal bone.

Carpal fractures can be a diagnostic challenge

If the fracture is stable, immobilization by casting is the treatment of choice

Q

This fracture is missed because:

A
  • 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

Q

Considerations for wrist fractures:

A

As ROM exercises are initiated for wrist, be sure pt exercises while grasping an object. This allows pt to isolate wrist extensors from the Ex Digitorum Communis (EDC). (it thinks it can lift the wrist)
- marker or dowel to flex the EDC when extending and flexing the wrist

66
Q

Regeneration Phase 2-6 weeks

A

Healing takes place- regrowth of bone & vascular tissue, soft callus
turns to hard callus & direct union

67
Q

Remodeling Phase 6 weeks to a year

A

Strong bone tissue (ossification) is at the fracture

rigidity of callus dramatically improves between 6 to 8 weeks.

68
Q

Complications Associated with Fractures; 1. Delayed Union or Non union caused by:

A

Infection
Poor blood supply
Fragments
Movement of parts after fixation, etc.

69
Q

Complications Associated with Fractures: Malunion

A

rotation of spiral fracture or angulation- healing but at unusual angles. Fracture healed in the wrong position.

70
Q

Choices for fracture fixation

A

-Fractures that are stable will often have closed methods of fixation such as a cast or splint.

Fractures that are displaced or unstable will require some form of internal fixation.

External fixation is used when traction is needed to hold a fracture out to length. Not seen as much with the development of the newer plate fixation techniques.

71
Q

Fracture Immobilization

A

cast or external fixator

72
Q

Internal Fixation

A 
Screws
Plates
K-wires
Tension bands
Wire loop
73
Q

Combination of fixation

A

splint with ORIF

74
Q

Complications associated with fractures

A

Adherence of tendons resulting from edema, surgery or soft tissue injury over a fracture.

Joint stiffness and contracture after immobilization.

Occasionally, development of CRPS (complex regional pain syndrome)

75
Q

The Unforgiving Elbow

A

High risk of contractures and motion loss following fractures and dislocations

Nerve injury often accompanies fractures of the elbow

High risk of the development of heterotopic ossification in the brachialis

76
Q

Brachialis: Tone Issues and adhesions

A

The brachialis runs across the anterior joint capsule and will adhere to it which will lead to motion loss in both flexion and extension.

77
Q

Facts about elbow injury

A

Loss of flexion is more limiting functionally
Extension loss is more common (-20)
Extension loss is more challenging

78
Q

Treatment for Non-displaced Fracture

A

Sling for a few days
Elbow flexion and extension with forearm in neutral
Supination and pronation with elbow flexed at 90
Week 3 AROM as tolerated
No resistance for 8 to 10 weeks

79
Q

Displaced Radial Head Fractures

A 
Require fixation (Usually plates and screws)
May or may not have a splint
Gentle AROM
Management depends on what other structures are involved
80
Q

Splint to prevent full extension for elbow dislocation

A

Splinted at 90 degrees initially. Extension is gradually increased weekly. Full extension allowed at 6 weeks but is usually limited.

81
Q

What is joint mobilization

A

Selective stretching of specific tissue around a joint without damaging adjacent tissue; Stretching a capsular structure in physiological planes.

82
Q

Purpose of joint mobilization

A

Remodel connective tissue to improve extensibility and reduce stiffness

Reduce pain and encourage relaxation

Bathe the joint in synovial fluid and nourish joint structures.

83
Q

Indications of joint mobilization

A

Stiff joints
To decrease pain
To prevent joint capsule tightening

84
Q

Contraindications of joint mobilization

A 
Joint replacements
Fractures that are not healed
Acute inflammatory or septic arthritis
Bone disease
Bacterial infection
Malignancy
Unstable joint
85
Q

Osteokinematics:

A

Movements produced by 2 adjacent bones (flexion, extension, abduction etc). We can see/observe these motions.

These are the motions we are familiar with that occur in the cardinal planes. These include flexion, extension, abduction, adduction, internal and external rotation etc.

86
Q

Arthrokinematics/Accessory:

A

essential movements that occur in joints as a result of physiologic (osteokinematic) motion but which cannot be produced my muscle action.

The motions occurring in the joint during motion. Spinning, rolling, gliding, sliding are necessary or impingement, compression, inflammation, stiffness and pain will occur.

87
Q

Arthrokinematics/Accessory:

A

essential movements that occur in joints as a result of physiologic (osteokinematic) motion but which cannot be produced my muscle action.

The motions occurring in the joint during motion. Spinning, rolling, gliding, sliding are necessary or impingement, compression, inflammation, stiffness and pain will occur.

88
Q

Concave

A

– hollowed or rounded inward like a “cave”.

89
Q

Convex

A

curved or rounded outward

Ice cream cone

90
Q

Convex moving on concave

A

Glide is to the opposite direction of movement. In other words The joint surface moves in the opposite direction the bone shaft is moving.

“Convex on Concave run the opposite way.”

ex) Glenohumeral joint

91
Q

Concave moving on convex:

A

Glide in the same direction as movement of the bone shaft.

“Concave on convex like a wrench moves a hex.”

Ex) IP joints

92
Q

Resting position

A

Maximum joint play - position in which joint capsule and ligaments are most relaxed
Evaluation and treatment position utilized with hypomobile joints

93
Q

Loose-packed position

A

Articulating surfaces are maximally separated
Joint will exhibit greatest amount of joint play
Position used for both traction and joint mobilization

94
Q

Close-packed position

A

Joint surfaces are in maximal contact to each other

95
Q

General rule of joint positions

A

Extremes of joint motion are close-packed, & midrange positions are loose-packed.

96
Q

Joint mobilization restores the accessory motions

A

(arthrokinematic motion) by gliding one joint surface on another, stretching peri-articular structures in the desired direction.

97
Q

Importance of arthrokinematic motion

A

Essential to normal joint motion.

Loss of accessory motion can be clinically detected with joint assessment and at times might be the only pathology causing the pain or problem.

Restoration of accessory/arthrokinematic movement must accompany and usually proceeds restoration of movement in restricted joints.

98
Q

Roll

A

A series of points on one articulating surface come into contact with a series of points on another surface
Rocking chair analogy; ball rolling on ground
Example: Femoral condyles rolling on tibial plateau
Roll occurs in direction of movement
Occurs on incongruent (unequal) surfaces
Usually occurs in combination with sliding or spinning

99
Q

Spin

A

Occurs when one bone rotates around a stationary longitudinal mechanical axis
Same point on the moving surface creates an arc of a circle as the bone spins
Example: Radial head at the humeroradial joint during pronation/supination; shoulder flexion/extension; hip flexion/extension

Spin does not occur by itself during normal joint motion

100
Q

Slide/Glide

A

Specific point on one surface comes into contact with a series of points on another surface

Surfaces are congruent
When a passive mobilization technique is applied to produce a slide in the joint – referred to as a GLIDE.

Combined rolling-sliding in a joint

101
Q

Compression

A

Decrease in space between two joint surfaces
Adds stability to a joint
Normal reaction of a joint to muscle contraction

102
Q

Distraction

A

Two surfaces are pulled apart

Often used in combination with joint mobilizations to increase stretch of capsule.

103
Q

Structures being assessed

A

Capsular tightness
Joint surface

131
Q

Paraffin wax

A

Heat Method: Conduction
-Liquid mixture of paraffin wax and mineral oil.

Usually comes pre-mixed in beads or blocks of paraffin.

Operating temperature: 125-130 degrees F.

Paraffin has a low specific heat, therefore the hotter temperature of 127 to 130 does not cause the tissue damage that a hot pack would at that same temperature. Specific heat is a measure of the heat required to raise the temperature of a given amount of a substance/tissue, one degree.

132
Q

Paraffin wax bath benefits

A

Great for osteo and degenerative arthritis (not for rheumatoid).

Great for working on composite flexion of digits. Can have patient either actively flex to their max range or tape them in flexion (Can also be done with hot packs). Use caution when doing this. Blood flow might be affected with stretch which will reduce tissue tolerance to heat creating a more risk of injury.

133
