ACL-friendly ski-bindings - presentation to IOC (pdf)


Newly updated and expanded version of “ACL-friendly Ski-Bindings” presentation by Rick Howell — on the interaction between ski-bindings and ACL biomechanics — to the  IOC (International Olympic Committee) Conference on Preventing Injury in Sports — Monte Carlo, Monaco, 2017.  

Available now.  

4-part slideshow presentation provides scientific-peer-reviewed research addressing how ski-bindings with non-pre-releasing, additional lateral-heel release can provide ACL, MCL and meniscus friendly skiing.  
All 4 parts:  US$39.

    Part-1.   Biomechanics.   Epidemiology and biomechanics of skiing ACL and MCL injuries — incidence and severity;  prevalence of injury-mechanisms;  computer-modeling / validation;  metallic-surrogate and test apparatus;  experimental test data;  conversion of resultant tibia-torques plus abduction-moments at ACL-rupture — out of an incommensurable state to a new paradigm — to a single-metric that establishes integrity-limits as a function of where the primary ACL and MCL injury-producing-loads uniquely enter a ski.

    Part-2.   Bindings.  Comparison of ordinary 2-mode alpine ski-bindings and extraordinary 3-mode Howell SkiBindings to the biomechanical thresholds established in Part-1.

    Part-3.   Settings.   Derivation of special, non-pre-releasing, lateral-heel release-settings for a full-range of skier biometrics — for ACL and MCL friendly skiing — ONLY for patented Howell SkiBindings.

    Part-4.   Annex.   Supplemental data and comments.

Howell SkiBindings is against (a) ski waist widths greater than 90mm  AND  (b) all 'pin-bindings’ (except Trab TR2 and Shift, though Shift cannot address ACL-friendly skiing) — due to their association with a new type of skiing-injury:  severe, high-energy tibia-plateau and tibial-tuberosity fractures.  Both types of 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 multiple-fragments, difficult surgical reconstruction, and 10 to 15-months of aggressive rehabilitation.  Fat skis on firm snow and/or pin-bindings in any snow-conditions are a serious problem for the sustainability of our beautiful sport.  (‘Pin-bindings’ are hardly “tech”.)
