Abstract: Bone compression systems for internal fixation of bone portions include one or more spring washers having ultra high load capacity and ultra low displacement to close diminution gaps that develop in a discontinuity between the bone portions after fixation. The spring washers, individually or in stacks of up to four, provide installation loads between 1500 N and 4000 N. After closing diminution gaps, the spring washers or stacks provide sustained loads between 1000 N and 3000 N which stabilize the bone portions sufficiently to permit early load bearing. The sustained loads correspond to sustained average local bone stress just below the bone growth trigger threshold stress. The additional loads of early load bearing will create average local bone stress above the bone growth trigger threshold. By bone stress repeatedly passing through the bone growth trigger threshold stress, bone healing is optimized.
