How the SPOrt™ Works

The SPOrt is designed to support the A2 or A4 pulleys as these are the most important pulleys, and the ones that climbers most frequently injure.  As you can see, in these X-rays, (with the SPOrts in place), and in the corresponding diagrams, they are in the correct location to support these critical structures.

The A2 SPOrt reinforces the A2 and C1 pulleys.

The A4 SPOrt reinforces the A4 and C2 pulleys.

After an acute pulley injury, with the SPOrt™ on the finger but not taped in place, as below, one can see that the tendon-phalanx distance (*TPD-a measure of pulley compromise) is increased.

However, if tape is applied as directed closing down the SPOrt™, as in the second diagram, the TPD is decreased and the flexor tendons are reduced back to the finger bone, (phalanx).

Any serious injury to a finger should be evaluated by a medical professional with knowledge of hand injuries in climbers. Ultrasound evaluations and in some cases MRI scans may be useful to guide treatment. In severe cases, surgery might be needed.


If you decide to treat yourself with a SPOrt™ for an acute injury, without seeking medical advice, you do so at your own risk.


The SPOrt™ is not designed for use in finger-crack climbing nor to allow an acutely injured climber to continue to climb or train without giving their body sufficient time to heal the pulley and then gradually strengthen it.


Using the SPOrt™ for a chronic injury to support a sore finger or stretched out pulley to alleviate soreness and tendonitis is safe, as long as it is not taped too tightly.

**Disclaimer:  The SPOrt must be taped securely in place to be effective.**

"I participated in Dr. Warme's study on the SPOrt and saw through an ultrasound machine the SPOrt keeping my A2 pulley closer to the bone as I crimped. This has given me great confidence in the product and I can't recommend it enough for any climber out there suffering through a pulley injury."
