【摘要】:目的:探討髖關節(jié)翻修術中生物型臼杯高位放置重建髖臼的可行性及中期療效。方法:2006年3月至2015年3月在髖關節(jié)翻修術中應用生物型臼杯高位放置技術的患者34例(35髖),男15例(15髖),女19例(20髖);年齡26~74歲,平均55歲。因無菌性松動翻修22髖,因關節(jié)置換術后感染翻修13髖。PaproskyⅡA型3髖、ⅡB型4髖、ⅡC型2髖、ⅢA型17髖、ⅢB型9髖。股骨側采用遠端固定組配式錐形柄。術后髖關節(jié)旋轉中心高度均大于2.5 cm,按旋轉中心高度分成兩組:適當高位放置組(旋轉中心高度2.5~3.5 cm)和高旋轉中心組(旋轉中心高度大于3.5 cm)。比較兩組術前及末次隨訪時Harris髖關節(jié)評分、疼痛視覺模擬評分(visual analogue scale,VAS)、雙下肢長度差、Trendelenburg征及跛行程度。攝髖關節(jié)正位X線片測量旋轉中心高度、旋轉中心至淚滴的水平距離,觀察臼杯周圍透光線及假體移位情況。結果:手術時間100~220 min,平均168 min。術中出血量300~1 200 ml,平均825 ml。隨訪時間12~116個月,平均49.2個月。末次隨訪時Harris髖關節(jié)評分由術前(36.52±17.17)分提高至(83.46±7.63)分,疼痛 VAS 評分由術前(8.06±1.24)分降低至(1.91±1.62)分,差異均有統(tǒng)計學意義(P0.05);俭y旋轉中心高度由術前(1.47±±0.33)cm提高至術后(3.85±1.13)cm,差異有統(tǒng)計學意義(t=12.15,P=0.00);旋轉中心至淚滴的水平距離術前(3.33±0.53) cm、術后(3.23±0.63) cm,差異無統(tǒng)計學意義(t=0.98, P=0.64)。末次隨訪時Trendelenburg征陽性7髖、陰性28髖,其中17髖由術前陽性轉為陰性;重度跛行1例、中度破行1例、輕度跛行8例、無跛行24例;下肢短縮由術前(1.84±1.92) cm降至(0.71±1.57) cm,差異有統(tǒng)計學意義(t=4.24,P= 0.00 )。6例應用特小臼杯極度高位放置(旋轉中心高度大于5.0 cm )的PaproskyⅢB患者Harris髖關節(jié)評分由術前 (26.65±13.46 )分提高至末次隨訪的(79.83±10.55)分,疼痛VAS評分由術前(8.50±1.38)分降至(2.83±2.64)分,差異均有統(tǒng)計學意義(P0.05)。1例術后4年出現臼杯松動,再次行翻修術。無假體相關感染、假體脫位、假體周圍骨折等并發(fā)癥發(fā)生。結論:生物型臼杯高位放置并盡量向內側移位能增加與宿主骨的接觸,臼杯適當高位放置和高位放置均能緩解疼痛和改善功能。手術簡化,尤其是使用特小臼杯極度高位放置適用于無法使用其他髖臼重建方法的情況。
