Howell ACL-Friendly Fixture™ (optional)

$399.00
Howell ACL-Friendly Fixture™         $399.        
Available now.  Optional, though suggested.

     Howell ACL-Friendly Fixture is an optional bench-mounted fixture that allows functional inspection of Howell SkiBinding lateral heel release (1).  See all 3 photos.  This unique fixture solidly secures any adult-size ski-boot upside-down onto any work bench for testing the function of Howell-specified lateral heel release and retention.  This device tests for 'valgus-dominant' ACL-friendly & MCL-friendly skiing-function.

     Some ISO-5355 alpine ski-boots perform adversely with lateral heel release:  this fixture assists with the testing of the complete ski-boot-binding system for functional-compatibility during lateral heel release and lateral heel retention.  (All AT ski-boot soles with metal dimples are incompatible with Howell SkiBindings.)

     This fixture includes a 1-piece, integrally-welded 3/16 inch thick solid stainless steel frame and foot with separately-attached stainless-steel sailing hardware to rigidly-affix any adult alpine ski boot during lateral heel release testing.  Mounting bolts are included.  Detailed instructions for use are included.

     Used in combination with a properly-tethered ski — the ski is slowly-loaded by a gloved-hand, laterally, at specified points along the length of the ski to verify the Howell-specified 'Cross-Over Point' where lateral-toe release switches to lateral-heel release.  ((For example, for an average U.S. male weighing 169-pounds, the Cross-Over-Point is located (on the ski) ~60cm aft of the projected axis of the tibia.))  Tape measure is included.

     Lifetime limited warranty.

     This is a powerful tool for validation, calibration, and demonstration of ACL-friendly & MCL-friendly ski binding function.

 

   Anti-pre-release.  ACL-friendly.

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.  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.
