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 biomechanics to the International Olympic Committee Conference on Preventing Injury in Sports — Monte Carlo, Monaco, 2017.
125-slide PDF-presentation provides scientifically-peer-reviewed research addressing how special ski-bindings can provide ACL/MCL-friendly skiing. All 3 parts included for $19 grand total.
Part-1. Epidemiology of skiing-ACL and MCL injuries — incidence and severity; prevalence of ACL and MCL injury-mechanisms; ACL-MCL computer-modeling / validation; metallic-surrogate and test-loading apparatus; experimental test data; conversion of resultant/combined tibia-torques and abduction-moments at ACL/MCL-rupture — to a unified-metric that establishes integrity-limits as a function of where the primary ACL and MCL injury-producing-loads enter a ski.
Part-2. 2D-biomechanical release envelopes of ordinary-2-mode alpine ski-bindings bindings — and extraordinary-3-mode alpine ski-bindings — compared with the ACL and MCL integrity limits that are derived in Part-1. Biomechanical proof that ordinary-2-mode bindings cannot address ACL or MCL integrity at any release setting, whereas specially-tuned, non-pre-releasing — extraordinary — 3-mode alpine bindings can address ACL-integrity.
Part-3. Biomechanical derivation of special non-pre-releasing lateral-heel release-settings for a full-range of skiers, large and small — for ACL and MCL friendly skiing — ONLY for patented Howell SkiBindings.

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”.)
