Skeletal traction

Although the use of traction has decreased over the years, an increasing number of orthopaedic practitioners are using traction in conjunction with bracing (see Milwaukee brace

Bryant's Traction

Bryant's traction is mainly used in young children who have fractures of the femur

from the hips and knees slightly flexed. Over a period of days, the hips are gradually moved outward from the body using a pulley system. The patient's body provides the countertraction.

Purpose

The purpose of traction is to:
  • To regain
  • To lessen or eliminate muscle spasms.
  • To relieve pressure on nerves, especially spinal.
  • To prevent or reduce skeletal deformities or muscle contractures.


In most cases traction is only one part of the treatment plan of a patient needing such therapy. The physician’s order will contain:
  • Type of traction
  • Amount of weight to be applied
  • Frequency of neurovascular checks if more frequent than every four (4) hours.
  • Site care of inserted pins, wires, or tongs
  • The site and care of straps, harnesses and halters
  • The inclusion of any other physical restraints / straps or appliances (eg. mouth guard)
  • the discontinuation of traction

Responsibility of initial application

The physician is typically responsible for initial application of traction and weights while the adjustment or removal (to perform ablution functions / physiotherapy) of skeletal traction weights will be based on the doctors charted plan.

In most cases cervical traction may be adjusted or temporarily removed, per physician order, by an orthopedic nurse who has documented competency to do so.

The alignment and moving of the patient will only be changed on physician's directive and the affected extremity will need to be maintained in proper alignment at all times with the ropes and traction straps - making sure the mentioned is unobstructed and weights hanging freely.

If it is necessary to move the patient while skeletal traction is in place, the patient should be moved in the bed with weights hanging freely.

In most cases traction will be applied for a number of weeks to months and Neurovascular checks will need to be performed by a nurse as ordered by the physician or as dictated
per traction unit policy.

Traction is an appropriate treatment for a number of medical problems including spinal deformities such as scoliosis.

Evidence basis

Lumbar spinal manipulation followed by Harrison
"mirror image methods" (lateral translation exercise and
traction) were found to produce statistically significant
and clinically significant reductions in pain and trunklist
posture, a finding not observed in the control group.
160
In fact, the control group’s lateral thoracic translations
were slightly worse at follow-up, possibly indicating
progression of the disorder. Because these trunk-list
postures are commonly associated with lumbar disc
herniation and lower back pain, randomized controlled
trials should be performed to evaluate the clinical significance
of restoration of normal spinal-alignment
biomechanics in chronic LBP pain subjects. Due to
discrepancy between our study findings and a previous
report, it is suggested that AP lumbo-pelvic radiographs
and posture of the trunk should both be used as outcome
measures in the treatment of the trunk-list deformity.
