FREE !   ACL Integrity with Ski Bindings by Rick Howell — an expanded presentation to the International Olympic Committee (IOC), March 16-18, 2017 in Monte Carlo — available now, N/C — is a 29 slide PDF-presentation that provides the scientific, biomechanical validation behind how the principle mechanisms of Howell SkiBindings provide ACL-friendly skiing. 

    First, the theoretical integrity-limits of the ACL are derived as a function of where forces that are associated with skiing ACL-injury events enter the ski

    Then, the release limits of ordinary 2-mode alpine ski bindings and the release limits of the new 3-mode Howell SkiBindings — are tested relative-to the above noted ACL integrity limits — by applying the same biomechanical test-method that is utilized above to derive the ACL integrity limits. 

   Please note that testing AT-binding release-function relative to ACL-integrity is a separate report that is not included with this presentation. 

   Also note that certain research studies that have reported on-slope electronic measurement of ski bindings relative to ACL-integrity — do so by incorrectly applying vector-transposition to analyze the lateral bending moment at the bottom (distal) end of the tibia, not across the knee.  These researchers confuse edging-moments with abduction-moments:  that research is invalid irrespectively of their 'professional' credentials:  they are so-called 'expert' witnesses for ordinary 2-mode ski binding companies.

    The abstract that accompanies this PDF presentation was peer-reviewed and approved by the IOC on Preventing Sports Injury — including peer-review by several orthopedic researchers who specialize in skiing-safety.  The presentation that is being offered, free, herein is an expanded, 29-page version of the 1-page abstract by Rick Howell — Mitigation of ACL Rupture in Alpine Skiing through Ski Bindings, in British Journal of Sports Medicine, 2017;51:283-412 [on-line:  http://bjsm.bmj.com/content/51/4/332.1]

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 Trab TR2 pin bindings) — are a serious problem for the sustainability of our beautiful sport:  the ISO standards on pin-bindings must be changed to reflect human-biomechanics.   References:  (1) Dominik Heim, MD;  SITEMSH-Japan, 2016.  (2) Zorko; Nemec; Matjacic; Olensek;  Alpine Skiing Simulations Prove Ski Waist-Width Influences Knee Joint Kinematics;  ISSS-Innsbruck, Austria, 2017.   (3) Stenroos; Pakarinen; Jalkanen; Mälkiä; Handolin;  Tibial Fractures in Alpine Skiing and Snowboarding in Finland: A Retrospective Study on Fracture Types and Injury Mechanisms in 363 patients;  Scand J Surg Off Organ Finn Surg Soc Scand Surg Soc., Sept 2015,  doi:10.1177/1457496915607410.  (4) Improved Short Term Outcomes in Tibial Plateau Fractures of Snow Sports Injuries Treated with Immediate Open Reduction Internal Fixation;  Janes, MD; Leonard, MSPH; Phillips, PA-C; Salottolo, MPH; Abbott, MD, Bar-Or, MD;  ISSS-Innsbruck, Austria, 2017.
