Howell Lateral-Heel Release-Test Fixture (Optional)


Howell Lateral-Heel Release-Test Fixture (sm)*        

Available now !


Optional — though suggested.

     Mostly for ski shops — but also available for skiers — this is a special, optional, bench-mounted test-fixture that assists with the functional inspection of the complete ski-boot-binding system for the special non-pre-releasing lateral-heel release-function that is uniquely specified for Howell SkiBindings.  Specially-tuned lateral-heel release limits abduction-moment loading that is associated with ACL, MCL and meniscus integrity.  See Menu —> Tech Info —> Release —> Part-2.  See all 4 photos, above.  

     Other items needed to validate Howell-specified lateral-heel release function:  (1) Howell SkiBindings;  (2) tape-measure (not included);  (3) calibrated torsional release torque setting**;  (4) workbench;  and (5) Howell SkiBindings lateral-heel release-setting specifications for the location on the tail of the ski for the ‘Transition Point’ (specifications are included with purchase; and see chart, below).  Howell specifications provide the boundary-condition where lateral-forces that are applied to the medial-edge of the ski — convert from lateral toe release to lateral-heel release.  

     The Howell Lateral-Heel Release-Test Fixture is ‘optional’ because ski shops and skiers can rely on the lateral-heel release visual indicator settings that are provided on the binding together with Howell-recommended lateral-heel release settings for each individual skier.  However, testing the function of the complete ski-boot-binding system for lateral-heel (abduction moment) release-function is suggested and provides a means to measure the influence of the boot within the full ski-boot-binding system — then take corrective-action to resolve any out-of-spec conditions (see ‘Troubleshooting’ in Owner’s Manual and/or Ski Shop Tech Manual).

     ‘Howell Lateral-Heel Release-Test Fixture’ is 1-piece, solid stainless steel including a fully-integrated stainless steel 'foot'.  ‘Includes stainless-steel sailing hardware and non-stretch (3,000 pound test) high-tech sailing lines to rigidly-secure any ski ski boot — alpine, AT, or Telemark.  Four (4) stainless steel bolts to mount the fixture to a sturdy workbench or ski-tuning bench are included.  Bench not included.

     Lifetime Limited Warranty.

     This is a robust test-fixture for validation, calibration, and/or demonstration of the special lateral-heel release function that is unique to Howell SkiBindings.  The fixture is optional for Howell SkiBindings.



   Anti-pre-release.  ACL-friendly.

Howell SkiBindings is against (a) ski waist widths greater than 100mm  AND  (b) all 'pin-binding's' (except new Trab TR2) — due to their association with a new type of skiing-injury:  severe, high-energy tibia-plateau and tibial-tuberosity 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 multiple-fragments, difficult surgical reconstruction, and 10 to 15-months of aggressive rehabilitation.  Fat skis on firm snow are a serious problem for the sustainability of our beautiful sport.   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.
