Femoral neck fractures seldom occur in hips with a significant degree of osteoarthritis. Experience with three hitherto undescribed fractures around hip nails suggests that the ridge of new bone which forms on the inferior part of the femoral neck in osteoarthritis increases the strength of the neck, thus decreasing the tendency to neck fractures.
股骨颈骨折很少发生在患有严重骨关节炎的髋关节中。对三例此前未描述过的围绕髋部钉的骨折的经验表明，骨关节炎时在股骨颈下部形成的新骨嵴增加了颈部的强度，从而降低了颈部骨折的倾向。
