摘要
目的:从解剖学角度证实,应用掌长肌腱转位修复桡尺远侧关节脱位的机理。方法:测定30侧上肢标本中掌长肌腱各段的宽度、厚度;对9条新鲜掌长肌腱进行拉伸试验。临床应用30例,将掌长肌腱近端以"8"字形穿过桡骨及尺骨骨孔,紧缩分离的桡尺远侧关节后固定于掌筋膜。结果:术后随访5个月～6年,X线片示:桡尺远侧关节间隙从术前的3.0～4.0mm,减小到术后的1.0～2.5mm,疗效满意。结论:掌长肌腱的长度、宽度适合于该术式的要求,拉力强度能满足术中关节拉拢,肌腱紧缩的需要。该术式方法简便,是修复桡尺远侧关节陈旧性脱位的有效方法。
Objective: To find the rationale of palmaris longus tendon transfer for treatment of distal radioulnar joint dislocation. Methods: The width and thickness of each segment of palmaris longus tendon were measured in 30 upper limb specimens. Traction test was done in 9 tendons from fresh cadavers. In 30 patients clinically, the palmaris longus tendon was pulled through the holes made in the radius and the ulna in '8' shape and reduced the gap of the distal radioulnar joint that was departed, and then the tendon was anchored on the palmer aponeurosis. Results: After follow-up of 5 months to 6 years, the gap of distal radioulnar joint was reduced to 1.0～2.5 mm from 3.0～4.0 mm before surgery in x-ray. The outcomes were satisfactory. Conclusions: The length and width of palmaris longus tendon is suitable for this technique. The strength is adequate to pull the joint together. This technique is simple and effective for treatment of old distal radioulnar joint dislocation,
