【摘要】 本文应用骨圆针—TJ骨水泥结构治疗脊柱骨折、脱位,并对该结构的机械性能进行了测定,抗弯强度达529.35kg/cm~2。骨圆针能显著增强骨水泥的机械性能。手术中脊柱立即得到固定,便于护理和康复。临床应用12例,平均随访19月,效果满意,无不良反应。介绍了制作及使用方法。更多还原

【Abstract】 <ABSTRACT>Mecbanical strength of steinmann-pin-reinforced bone cement was(Continued on page 173 )(Continued from page 183 )investigated. Such reinforcement would greatly increase the bending strength ofbone cement (529.35kg/cm2 ), for immediate fixation of the spine duringoperation, facilitating postoperative care and rehabilitation of the patient. 12patients with spinal fracture-dislocation were treated using this technique andfollowed-up for 19 months without any complication. Technical details ofthe procedure were described,更多还原
