【摘要】：目的探討對(duì)喙肩弓進(jìn)行不同程度破壞時(shí)肩關(guān)節(jié)前上方穩(wěn)定性所受到的影響。方法選取新鮮成人冷凍肩關(guān)節(jié)尸體標(biāo)本36個(gè),隨機(jī)平均分為3組后進(jìn)行不同的處理。組1,保留完整的喙肩韌帶;組2,破壞一半喙肩韌帶;組3,將喙肩韌帶全部破壞。然后分別將肩關(guān)節(jié)標(biāo)本固定生物力學(xué)試驗(yàn)機(jī)上進(jìn)行力學(xué)實(shí)驗(yàn);對(duì)肱骨干施加軸向壓力時(shí),肱骨頭向前上方移動(dòng),記錄肱骨頭在50 N壓力時(shí)的位移距離。結(jié)果在50 N壓力作用下,組1、2、3肱骨頭位移距離分別為(2.50±0.59)、(5.38±0.71)、(6.49±0.81)mm。3組數(shù)據(jù)組間比較均存在明顯統(tǒng)計(jì)學(xué)差異(P0.05)。結(jié)論喙肩弓的破壞會(huì)影響肩關(guān)節(jié)前上方的穩(wěn)定性。喙肩弓的破壞程度越大,肩關(guān)節(jié)前上方的穩(wěn)定性就越差。
[Abstract]:Objective to explore the effect of the stability of shoulder joint above the beak shoulder arch. Methods 36 cadaver specimens of fresh adult frozen shoulder joints were selected and divided randomly into 3 groups to carry out different treatments. Group 1, the intact beak shoulder ligament was retained; group 2, half of the beak shoulder ligament was destroyed; and group 3, all the beak shoulder ligaments were destroyed. Then the mechanical experiment was carried out on the fixed biomechanical test machine of shoulder joint specimens. When the humeral stem was applied axial pressure, the humeral head moved forward and recorded the displacement distance of the humeral head at 50 N pressure. The displacement distance of the humeral head of the group was (2.50 + 0.59), (5.38 + 0.71), (6.49 + 0.81) mm.3, respectively, under the action of 50 N pressure. There were significant statistical differences between the groups (P0.05). Conclusion the damage of the beak shoulder arch could affect the stability of the anterior shoulder joint. The greater the damage degree of the beak shoulder arch, the worse the stability of the anterior shoulder joint.
