We report the effects of early and late ultrasound treatment protocols on healing of surgically lacerated zone 2 flexor tendons in a chicken model. Ultrasound was administered directly using a coupling gel. Treatment was shown to increase range of movement, to advance scar maturation and to decrease the amount of inflammatory infiltrate around the repair site. No adverse effects on tensile strength were noted in either group. Early (starting 7 days post-operatively) administration was more effective than late (starting 42 days post-operatively) administration in achieving these effects. These results suggest that ultrasound therapy may be of benefit in the early healing process of flexor tendon lacerations.
我们报告了早期和晚期超声治疗方案对鸡模型中手术切割的2区屈肌腱愈合的影响。使用耦合凝胶直接进行超声治疗。结果表明，治疗可增加活动范围，促进瘢痕成熟，并减少修复部位周围的炎性浸润量。两组均未观察到对拉伸强度的不良影响。在实现这些效果方面，早期（术后7天开始）给药比晚期（术后42天开始）给药更有效。这些结果表明，超声治疗可能对屈肌腱撕裂的早期愈合过程有益。
