Spinal Traction Flashcards
What is spinal traction?
A mechanical force applied to the body that separates the joint surfaces and elongates surrounding soft tissues.
Different Types of Spinal Traction = ?
Different Types of Spinal Traction - Lumbar Traction:
1) Mechanical
- Static
- Intermittent
2) Inversion
3) Self-Traction/Positional
4) Manual
Mechanical Traction
Advantages & Disadvantages = ?
Mechanical Traction:
- Advantages:
- Force & time well controlled
- Readily graded
- Replicable
- Does not require constant clinician attention
- Static or intermittent traction
- Disadvantages:
- Expensive
- Time-consuming to set up
- Lack of patient control or participation
- Restriction by belts poorly tolerated by some patients
- Mobilizes broad region rather than specific spinal segments
Manual Traction
Advantages & Disadvantages = ?
Manual Traction:
- Advantages:
- Minimal equipment required
- Short set-up time
- Force can be finely graded
- The clinician is present throughout the treatment
- Trial: Can be applied briefly, before mechanical traction, to determine if mechanical traction will be tolerated
- It can be used with patients who do not tolerate tight belts
- Disadvantages:
- Limited maximum traction force
- Amount of traction force cannot be easily replicated or specifically recorded
- Cannot be applied for a prolonged period of time
- Required a skilled clinician to apply
- Can be labor intensive for PT
Traction - Precations = ?
Traction - Precations:
i) Structural diseases affecting the spine
- Tumor, Infection, Osteoporosis,
- Prolonged systemic steroid use
ii) When pressure from belts may be hazardous
- Pregnancy, Hiatal hernia, Vascular compromise, Osteoporosis
iii) Displacement of annular fragment
- Traction will not change the position of the fragment
iv) Medial disc protrusion (see next slide for details)
v) When severe pain fully resolves with traction
- Increased compression on nerve root can cause complete nerve block
vi) Claustrophobia or psychological aversion
vii) Inability to tolerate prone or supine positions
viii) Disorientation
ix) TMJ problems or dentures (for cervical traction)
What are the physiological effects of spinal traction?
- Distracts joint surfaces
- Stretches soft tissues,
- Reduces disc protrusions,
- Relaxes muscles.
What are the clinical indications for using spinal traction?
Back or neck pain with or without radicular symptoms, caused by disc bulge or herniation, and nerve root impingement.
What are the contraindications for spinal traction?
- Unstable fractures
- Cord compression
- Fused vertebrae
- Acute injury or inflammation
- Joint hypermobility or instability
- Uncontrolled hypertension
How does mechanical traction differ from manual traction?
Mechanical traction allows for controlled force and timing, whereas manual traction requires a skilled clinician and cannot be easily replicated or prolonged.
What are the benefits of inversion traction?
Minimal equipment needed, easy for the patient to perform, and can be done in various environments.
Types of Cervical Traction = ?
- Mechanical
- Manual
- Wall mounted or “over the door” traction units
- Other home units (Saunders)
What is the primary mechanism proposed for traction reducing herniated nucleus pulposus (HNP)?
Reduction of disc protrusion, thus relieving compression on spinal nerves.
What specific settings are recommended for lumbar spine traction to address disc problems?
- 25% of body weight
- 60 seconds hold / 20 seconds relax
- 20-30 minutes
What parameters are advised for cervical spine traction during the acute phase?
- 7-9 lbs force
- Static
- 5-10 minutes
What should be assessed before applying spinal traction?
- Type of traction
- Patient position
- Traction force
- Duration and frequency of treatment
- Patient’s response.
Prone mechanical traction signs of nerve root compression = ?
(1) Peripheralization with repeated lumbar extension
(2) Positive crossed SLR
What are the adverse effects of spinal traction?
Increased symptoms with high-force treatments, rebound pain increases, and potential lumbar radiculopathy from cervical traction.
