Abstract

Bones with retained screws gradually regain normal strength but upon removal the strength drops to that of bones with fresh holes. This strength loss is probably attributable to microdamage occurring to the bone surfaces at the time of removal.

摘要

留有螺钉的骨骼会逐渐恢复正常强度，但取出螺钉后，其强度会降至有新钻孔的骨骼的强度水平。这种强度损失可能归因于取出螺钉时骨骼表面发生的微损伤。
