目的探讨采用数字化模板联合骨性参数测量在人工全髋关节置换术（total hip arthroplasty,THA）前选择关节假体的准确性及应用价值。 方法2012年9月－2013年6月，对13例拟定THA治疗患者通过术前测量骨性参数及数字化模板，辅助假体型号选择及制定术前计划。男4例，女9例；年龄41～79岁，平均54.08岁。左髋8例，右髋5例。股骨头缺血性坏死8例；股骨颈骨折5例，其中伴股骨头缺血性坏死3例。 结果手术时间140～254 min，平均191.8 min。术中2例输血，6例使用血浆代用品补充血容量。术中假体植入时无股骨或髋臼周围骨折；术后无下肢静脉血栓形成，其中2例下肢动脉斑块形成。患者均获随访，随访时间12～24个月，平均17.3个月。患者疼痛症状均缓解，患肢功能显著改善。股骨头缺血性坏死患者Harris评分从术前（54.0±12.9）分提高至术后3个月（91.1±4.1）分，差异有统计学意义（t=7.259，P=0.000）。术前假体选择型号与实际型号比较，股骨假体获优9例，良3例，差1例，优良率92.31%；髋臼假体获优7例，良4例，差2例，优良率84.62%。 结论THA术前采用数字化模板联合骨性参数测量可准确预估假体型号，提高假体选择准确性
