PURPOSE
To identify the wrist tendon most effectively maintaining the trapezial space in interpositional arthroplasty in osteoarthritis of the carpometacarpal joint of the thumb.
METHODS
The morphometrics of the os trapezium and the tendons of the flexor carpi radialis, extensor carpi radialis longus, and abductor pollicis longus were determined. The stiffness and compressive loading characteristics of the rolled-up tendons were compared to the os trapezium.
RESULTS
No significant morphometric differences between the three tendons were found. The mass and volume of the trapezium was significantly larger when compared to the tendon balls. No significant differences in the compressive loading resistance were found between the tendons, but the mean stiffness was 85% lower when compared to the os trapezium.
CONCLUSIONS
Neither tendon material approached the volume nor the stiffness provided by the os trapezium. Any tendon is considered to insufficiently maintain the trapezial space following trapeziectomy.
目的
确定在拇指腕掌关节骨关节炎的间置关节成形术中最有效地维持大多角骨间隙的腕部肌腱。
方法
测定大多角骨以及桡侧腕屈肌、桡侧腕长伸肌和拇长展肌肌腱的形态学指标。将卷起的肌腱的刚度和压缩载荷特性与大多角骨进行比较。
结果
未发现这三条肌腱之间存在显著的形态学差异。与肌腱球相比，大多角骨的质量和体积显著更大。肌腱之间在抗压载荷方面未发现显著差异，但平均刚度比大多角骨低85%。
结论
没有一种肌腱材料在体积或刚度上能达到大多角骨所提供的水平。任何肌腱在大多角骨切除后都被认为不足以维持大多角骨间隙。
