The Swiss Cheese Effect: A Biomechanical Study of Fifth Metacarpal Structural Integrity After Multiple Kirschner Wire Passes

Purpose: Percutaneous pinning is common in hand surgery. There is no defined threshold for how many extra passes create a clinically vulnerable bone at risk for fracture. Our study examined whether extra Kirschner wire (K-wire) passes meaningfully weaken the fifth metacarpal. Methods: Paired cadaver...
