目的 總結(jié)交鎖髓內(nèi)釘動(dòng)力化固定對(duì)骨折愈合的影響，分析動(dòng)力化固定后可達(dá)到正常愈合的類型。 方法回顧性分析2005年6月－2010年8月30例初始行靜力鎖定后再行動(dòng)力化固定患者臨床資料。男25例，女5例；年齡18～60歲，平均34歲。股骨干骨折26例，轉(zhuǎn)子下骨折4例。均為閉合損傷。根據(jù)AO分型：A1型2例，A2型2例，A3型1例，B1型5例，B2型6例，B3型2例，C1型8例，C2型4例。根據(jù)骨折或不愈合端的力學(xué)穩(wěn)定性和生物活性分型：穩(wěn)定/增生型8例、穩(wěn)定/萎縮型5例、不穩(wěn)定/增生型9例、不穩(wěn)定/萎縮型8例。于初次靜力釘術(shù)后6～18周，平均14周后行髓內(nèi)釘動(dòng)力化固定。 結(jié)果術(shù)后患者切口均Ⅰ期愈合。30例均獲隨訪，隨訪時(shí)間6～18個(gè)月，平均12個(gè)月。24例骨折于動(dòng)力化固定后3～6個(gè)月完全愈合，4例于7～11個(gè)月延遲愈合，2例不愈合。3例不穩(wěn)定/萎縮型患者出現(xiàn)明顯股骨短縮，1例不穩(wěn)定/萎縮型患者出現(xiàn)旋轉(zhuǎn)移位。 結(jié)論髓內(nèi)釘動(dòng)力化治療股骨干骨折不愈合療效確切，但不穩(wěn)定/萎縮型患者行動(dòng)力化固定術(shù)后并發(fā)癥較多。
