The Spinal Traction Unit is based on Dennis Newton’s method of reduction. This method is being used in South Africa and New Zealand.

How Does It Work?

The Spinal Traction Unit uses a rack and pinion mechanism that is driven via a hand-operated worm-drive reduction device.

A  mechanical load gauge gives an accurate read-out of the traction force. As the mast is raised, the traction force gradually increases and the traction angle increases, causing the patient’s head to bend forwards (flexion). Flexion and traction are the key components of any reduction of cervical spine dislocation.

Critical 4-hour Window

We know that the first 4-hours after suffering a cervical spine dislocation are critical. The quicker the injury is reduced, the higher the chance the patient has of full recovery. The Spinal Traction Unit was designed with this in mind.

The Spinal Traction Unit is quick and easy to use by trained registrars or specialists. This means the patient can be seen more quickly; therefore achieving reduction within the critical 4-hour window is more attainable and their chance of recovery significantly higher.

A New Way to Treat Cervical Spine Dislocations


Easy to store.
Fast to setup and use by trained registrars and specialists.


Ease of use and accessibility makes treatment within the critical 4-hour window achievable.


Treatment is more controlled, with less chance of Gardener-Wells pin cut outs.


Trials have seen 80% of patients walk away—20% more than using conventional traction methods.
