摘要:
目的  探讨跖肌腱不同部分的力学性能差异,为临床选用跖肌腱作为自体移植材料提供生物力学依据。 方法  新鲜意外死亡成人尸体8具共计15侧跖肌腱,分别截成长约6 cm的试件共56例,分为上段、中段、下段3组,对其中50例进行拉伸试验,其余6例在预定应力分别为30、40、50 Mpa的拉伸作用后进行组织学观测。 结果  跖肌腱的平均最大载荷、拉伸强度、弹性模量分别为(83.19±42.52)N, (60.32±21.80)、(714.83±285.44)MPa,其中下段的拉伸强度显著大于上、中段。 结论  跖肌腱的生物力学性能适应于自体移植材料的需要。
Abstract:
Objective    To provide the biomechanical basis of plantaris tendon for clinical autotransplantation.     Methods    Fifteen plantaris tendons from 8 fresh adult cadavers were cut into 56 segments with about 6 cm lengths in each. The segments were divided into 3 groups: upper, middle, and lower segments. Fifty segments were taken for the tensile test, while the other six segments were loaded under 30 MPa, 40 MPa, and 50 MPa respectively. The histologic structure of the tendons was observed under the microscope after presumptive load.     Results    The average limit load, tensile strength and elastic modulus of the plantaris tendon were (83.19±42.52) N, (60.32±21.80) MPa, and (714.83±285.44) MPa respectively. The tensile strength of the lower segments was significant higher than the upper and middle segments.     Conclusion    The biomechanical property of the plantaris tendon is accommodative for autografting.
