目的 腱- 骨愈合是肩袖損傷修復(fù)的關(guān)鍵因素，通過生物力學(xué)及組織學(xué)觀察探討不同界面處理方法對兔肩袖止點腱- 骨愈合的影響。 方法 取42 只成年日本短耳兔，雌雄不限，體重2.0 ～ 2.5 kg，隨機分為3 組，分別為皮質(zhì)骨層組（n=18）、松質(zhì)骨層組（n=18）、空白對照組（n=6）。空白對照組不作任何處理，作為正常對照；皮質(zhì)骨層組：全層切斷岡上肌腱中1/2 部分，將岡上肌腱直接縫合固定于肱骨大結(jié)節(jié)；松質(zhì)骨層組：全層切斷岡上肌腱中1/2 部分，去除肱骨大結(jié)節(jié)骨皮質(zhì)，將岡上肌腱縫合固定于肱骨大結(jié)節(jié)。術(shù)后4、8 周處死實驗動物，完整切取岡上肌腱與肱骨大結(jié)節(jié)及連接部，行大體觀察、HE 染色及生物力學(xué)測定。 結(jié)果 術(shù)后4 周，皮質(zhì)骨層組和松質(zhì)骨層組標本的岡上肌均較空白對照組萎縮，腱- 骨連接部界限不明顯；術(shù)后8 周，兩組岡上肌與空白對照組比較已無明顯差異。組織學(xué)觀察示皮質(zhì)骨層組術(shù)后4 周，界面組織層與新生骨組織層移行尚可；術(shù)后8 周，界面組織層與新生骨組織層逐漸移行，骨側(cè)形態(tài)接近正常。松質(zhì)骨層組術(shù)后4 周，界面組織層與新生骨組織層連接不緊密，膠原纖維排列凌亂；術(shù)后8 周，骨側(cè)大量新生骨組織，界面組織層變薄，平行的膠原纖維長入。生物力學(xué)測試示術(shù)后4、8 周，皮質(zhì)骨層組最大負荷均較松質(zhì)骨層組高，且每組術(shù)后8 周的最大負荷均較術(shù)后4 周高，差異均有統(tǒng)計學(xué)意義（P lt; 0.05）；除抗拉強度及術(shù)后4 周兩組間斷裂強度外，其余結(jié)果比較差異均有統(tǒng)計學(xué)意義（P lt; 0.05）。 結(jié)論 兔肩袖斷裂模型中，界面處理至皮質(zhì)骨層在愈合強度及程度方面均優(yōu)于處理至松質(zhì)骨層。
