PDF Research Presentation, International Olympic Committee conference, FREE !
FREE ! ACL Integrity with Ski Bindings — PDF Presentation to International Olympic Committee, March 16-18, 2017, Monte Carlo, Monaco, by Rick Howell — available now — is a 29 slide PDF-presentation that provides the breakthrough basis behind how human-biomechanics interact with the principle mechanisms of Howell SkiBindings that provide ACL-friendly skiing. Theoretical integrity-limits are derived for the ACL as a function of where the forces that are associated with certain skiing-events enter the ski (this is first-ever data). These integrity-limits are then utilized as the basis to test different types of alpine ski-binding function, including a comparison between ordinary 2-mode bindings and the extraordinary new 3-mode Howell SkiBindings (AT-binding testing is a separate report, not included with this presentation).
The abstract that accompanies this PDF presentation was peer-reviewed and approved by the IOC on Preventing Sports Injury — several peer-reviewers specialize in skiing-safety research. This PDF presentation is an extension of the published-version of the 1-page abstract that is also-available, on-line, free: Howell, R.J., Mitigation of ACL Rupture in Alpine Skiing through Ski Bindings, British Journal of Sports Medicine, 2017;51:283-412.

In addition to the above research, Howell SkiBindings company is against (a) ski waist widths greater than 87mm AND (b) all 'pin-binding's' (except new Trab TR2) — due to (a.i) their association with a new type of skiing-injury: severe, high-energy tibia-plateau fractures, severe tibial-tuberosity fractures, cumulative miniscus-damage, and MCL-rupture; and (b.i) due to high-energy, spiral-tiba-fractures. Both new types of skiing injuries are the fastest-growing categories of injuries in skiing — matching the growth of fat-skis and pin-bindings. The high-energy nature of the new types of skiing fractures involve many multiple-fragments, difficult surgical reconstruction, and 10 to 15-months of aggressive rehabilitation. Fat skis (on firm snow) and pin-bindings (in any snow) ((except the new Trab TR2)) — are a serious problem for the sustainability of our beautiful sport: the ISO standards on pin-bindings are knowingly wrong: they are about money; political-engineering; patent portfolios; and must be immediately changed to reflect human-biomechanics, not just manufacturing-tolerances.
