To determine the influence of suture patterns on resistance to gap formation after tendon plating STUDY DESIGN: Ex vivo study SAMPLE POPULATION: Suspensory ligament and superficial and deep digital flexor tendons harvested from 16 neonatal cadaver foal limbs.
Each tendon/ligament from a given limb was randomly assigned to one of three treatment groups consisting of a 7-hole veterinary cuttable plate fixed with alternating simple interrupted, figure-8, or hybrid suture patterns. The constructs were distracted at a rate of 1.0 mm/s to failure, as determined by the formation of a 1 mm gap for initial failure and a 3 mm gap for ultimate failure. The mode of failure was also recorded.
Constructs prepared with hybrid and figure-8 patterns sustained over 2× higher (p < .01) forces before gap formation compared to those prepared with a simple interrupted pattern. No difference was identified between tendons whose plate was secured with hybrid or figure-8 suture patterns. Mode of failure between groups did not differ.
The figure-8 and hybrid patterns described herein improved the resistance to gap formation of plated tendons compared to an alternating simple interrupted pattern described previously.
Figure-8 and hybrid patterns should be considered over simple interrupted patterns to improve resistance to gap formation in horses undergoing tendon plating.
确定缝线模式对腱板后间隙形成阻力的影响
离体研究
取自 16 个新生死胎马肢的悬韧带和浅、深指屈肌腱。
每条来自特定肢体的肌腱/韧带均随机分为三组，每组包含 7 孔兽医可切割板，固定有交替的简单间断、8 字或混合缝线模式。构造以 1.0mm/s 的速率分离，直至出现 1mm 间隙（初始失效）或 3mm 间隙（最终失效）为止。还记录了失效模式。
与采用简单间断模式相比，采用混合和 8 字模式制备的结构在间隙形成之前能够承受超过 2 倍的力（p<.01）。用混合或 8 字缝线模式固定的板的肌腱之间没有差异。组间的失效模式没有差异。
与之前描述的交替简单间断模式相比，本文所述的 8 字和混合模式可提高腱板的抗间隙形成能力。
在接受腱板固定的马中，应考虑 8 字和混合模式，以提高对间隙形成的抵抗力。
