How to prevent the dreaded "Hook of Hamate" fracture.
The most distinct injury in golf is fracture of the Hook of the Hamate—a small, hook-shaped bone in the wrist on the pinky side (hypothenar eminence). In the simulator age, this injury is becoming more common due to firm mats and steep impact angles ("Grounding the Club").
If you take deep divots on grass, you are a "digger." On a fairway, the club cuts through the turf. On a mat, the club bounces or stops abruptly. This sudden deceleration sends a massive shockwave up the shaft and into the lead wrist.
Check Your Data: Look at Angle of Attack. If you are steep (e.g., -6° or more with a 7-iron), you are at high risk on firm mats.
Budget mats often lack a distinct "give" layer. Hitting fat shots on these surfaces is like hitting concrete.
The Fix: Invest in a quality hitting strip (like a Fiberbuilt or Holy Grail strip) that allows the clubhead to travel "through" the turf.
Sim golf can induce tension. A death grip on the club reduces wrist mobility and prevents the natural release, transferring more shock to the bones. Research shows that a "Palmar Hamate Grip" (butt end in palm) combined with tight pressure increases force on the hamate by nearly 4x. Lighten your grip pressure to 4/10. If you struggle to change your grip, our coaching team can help you find a neutral, safe hold.
Wrist pain should never be ignored. It can lead to months in a cast. Get a screening to check your wrist mobility and grip mechanics.
