discontinued Lossing 90/90 Clinic Unit FAQ

What is the 90/90 Position?

The 90/90 Position is a right angle bend (90 degrees) at both the hip and the knee joints.

How do I know if the 90/90 Positioner is something that will help my patient?

A simple test will determine if you are a good candidate for treatment with the 90/90 Positioner. Simply lie on your back and have someone lift your lower legs and hips until they are in the 90/90 position. This gentle lifting is performed to take the pressure off your lower back. If you feel any relief from this, the 90/90 Positioner will help you.

What if I need to use the 90/90 traction at home?

We offer the 90/90 Positioner Unit designed for home use.

Is the 90/90 Positioner designed to help acute or chronic pain?

The Lossing™ 90/90 Clinic Unit is used very successfully for both the acute and the chronic condition. We offer two different style 90/90 Pelvic Tilt Belts that have been designed to target each condition. The Standard Belt is designed for the person with an acute phase condition or sensitive lumbosacral junction. The Mobilization Belt has an added sacral gripper to aid in even greater pull while in traction and is designed for the chronic condition, a compressed lumbo-sacral junction, sacral strain, and SIJ misalignment.

Why is elevating my knees so important? Why is lying with my legs at a 90 degree angle so crucial?

Lying with your hips and the knees in the 90/90 Positioner relaxes your back musculature allowing normalization of the low back. The 90/90 Pelvic Tilt Belt is designed to hold the pelvic girdle and assist in rotation while obtaining separation of the lower vertebrae while in traction, giving relief to pain. Research has shown that at the 90/90 position there is less pressure (least loading at L4-L5) on the lumbar spine.

Why lie on a wedge? Why not just lie flat and use the 90/90 Backtrac Unit?

The 15 degree angle wedge stabilizes the spine in a neutral position and prevents flexion (bending) of the spine. Preventing flexion of the spine causes the vertebrae to separate evenly.

After I put the Pelvic Tilt Belt on and clip the patient into traction, how far do I pull the patient up?

When using the 90/90 Back Traction Unit the goal is to lift the patient just high enough to slip the flat of your hand under your sacrum. At this level of traction you are gently providing enough pull to separate the vertebrae evenly, which results in decompression and relief of tension on the spine. If you pull too far up, you will place the patient in flexion. Keep a neutral position for best results.

How long is traction treatment time?

In general, people begin suspension with a five minute session. Gradually they increase this to fifteen to twently minutes. We recommend NOT exceeding twenty minutes in traction.

Can ice or heat be used while in traction?

Yes, by placing the heat/cold pack on the wedge before lying down. Use whichever is more beneficial. However, heat or ice prior to traction usually works better.

I purchased a Lossing™ 90/90 Clinic Backtrac from a company called Lossing Orthopedic years ago. Is this he same product?

The Lossing™ 90/90 Clinic Unit Backtrac was developed by the current co-owner of VMG Medical and founder of Lossing Orthopedic, Wallace Lossing, C.O. He and his partner Beverly Sweetman, P.T. have received many requests for the original unit. This is now available for your clinic.
