摘要

目的从生物力学角度评价采用真皮增强术（DA）与标准唇骨修复术（SLR）和骨块增强术（BBA）在治疗亚临界盂骨丢失的尸体模型中的稳定性。方法对8例尸体肩部标本进行分离解剖，只留下唇部组织。标本固定在定制固定装置上，盂肱外展60°，外旋30°，肩胛骨前倾20°，盂肱受压40 N。在重复测量设计中，标本在5种状态下进行测试：原生，缺陷（15%盂骨丢失），SLR， DA和BBA。在前下缘以1 N/s的速度脱位。记录最大载荷和脱位距离并进行统计分析。结果缺损状态和SLR的最大负荷显著小于原生状态（P = 0.005和P = 0.008）和BBA （P = 0.014和P = 0.022）。缺陷态（P < .001）和SLR （P < .001）与原生态相比，到位错的距离明显减小。与BBA相比，缺陷状态、SLR和DA到位错的距离显著缩短（P < 0.001, P < 0.001, P < 0.001）。DA到位错的距离明显大于缺陷状态（P < 0.001）和SLR （P = 0.001）。结论同种异体真皮移植修复具有与原生状态相似的生物力学特征，与SLR相比，脱位距离增加，脱位力增大。与自然状态相比，BBA恢复了脱位距离，导致最大载荷无显著增加。唇侧修复术是治疗亚临界盂骨丢失的一种替代方法，可以潜在地减轻骨移植的不良反应。未来的临床研究是必要的。

Biomechanical Effect of Dermal Allograft or Bone Block Augmentation on Standard Labral Repair in a Time-Zero Cadaveric Model of Glenoid Bone Loss

Purpose

To biomechanically evaluate the stability of a labral repair technique using dermal augmentation (DA) compared with standard labral repair (SLR) and bone block augmentation (BBA) in the context of subcritical glenoid bone loss in a cadaveric model.

Methods

Eight cadaveric shoulder specimens were disarticulated and dissected, leaving only labral tissue. The specimens were secured to custom fixtures with 60° of glenohumeral abduction, 30° of external rotation, 20° of scapular anterior tilt, and 40 N of glenohumeral compression. In a repeated-measures design, the specimens were tested in 5 states: native, defect (with 15% glenoid bone loss), SLR, DA, and BBA. Dislocation was performed at 1 N/s over the anterior-inferior rim. Maximum load and distance to dislocation were recorded and statistically analyzed.

Results

Maximum loads for the defect state and SLR were significantly less than those for the native state (P = .005 and P = .008, respectively) and BBA (P = .014 and P = .022, respectively). The distance to dislocation decreased significantly for the defect state (P < .001) and SLR (P < .001) compared with the native state. The distance to dislocation for the defect state, SLR, and DA was significantly reduced compared with BBA (P < .001, P < .001, and P < .001, respectively). The distance to dislocation was significantly greater for DA than for the defect state (P < .001) and SLR (P = .001).

Conclusions

Dermal allograft repair showed similar biomechanical characteristics to the native state and showed an increased distance to dislocation and higher forces at dislocation compared with SLR. BBA restored the distance to dislocation and resulted in non-significantly increased maximum loads when compared with the native state.

Clinical Relevance

DA of labral repair is an alternative procedure for subcritical glenoid bone loss that potentially mitigates adverse effects from bone grafting. Future clinical investigation is warranted.
