摘　　要：目的探讨声触诊组织量化成像(VTIQ)技术评价中青年男性急性闭合性不完全跟腱断裂开放性修复术前及术后跟腱弹性特征的价值。方法选取32例中青年男性急性闭合性不完全跟腱断裂患者,采用VTIQ获得双侧跟腱速度模式图,于中立位测量跟腱远段(跟腱跟骨附着处以上5 cm)、中段(跟腱跟骨附着处以上>5~10 cm)及近段(跟腱跟骨附着处以上>10 cm至肌-腱结合处)SWV值,比较术前1周、术后12周和24周两侧跟腱对应节段SWV值。结果术前1周患侧跟腱SWV值均低于健侧对应节段(P均<0.001),且双侧跟腱远段SWV值均高于同侧中段及近段(P均<0.01);术后12周患侧跟腱中段及远段较健侧对应节段SWV降低(P均<0.001);术后24周患侧跟腱远段较健侧远段SWV值降低(P<0.001)。患侧跟腱各段SWV值随时间延长而逐渐增高,两两时间点比较差异有统计学意义(P均<0.01)。结论VTIQ可量化评价急性闭合性不完全跟腱断裂术前及术后跟腱弹性;术后可采用VTIQ为跟腱各节段弹性提供客观评估指标。Objective To explore the value of virtual touch tissue imaging quantification(VTIQ)in evaluation of pre-and post-operative elasticity of incomplete acute closed ruptured Achilles tendon in young and middle-age men.Methods A total of 32 patients with unilateral incomplete acute closed ruptured Achilles tendon were enrolled.VTIQ examination was performed on bilateral Achilles tendon for speed mode.Achilles tendon was divided into distal segment(5 cm above insertion at the attachment of Achilles tendon),middle segment(>5—10 cm above insertion at the attachment of Achilles tendon)and proximal segment(from>10 cm above insertion at the attachment of Achilles tendon to musculotendinous junction).SWV was obtained,and then statistical analysis was performed in a neutral position 1 week before,12 weeks and 24 weeks after operation.Results SWV of ruptured Achilles tendon was lower than that of healthy side(all P<0.001),of distal segment was higher than of middle and proximal segment for bilateral Achilles tendon(all P<0.01).Twelve weeks after operation,SWV of the middle and distal segment of the healing Achilles tendon were both lower than the healthy side(both P<0.001),while 24 weeks after operation,SWV of distal segment of the healing Achilles tendon was lower than the healthy side(P<0.001).SWV of healing Achilles tendon gradually increased with time going,the difference between the two time points is statistically significant(all P<0.01).Conclusion VTIQ can be used to quantitatively observe the elasticity of incomplete acute closed ruptured Achilles tendon pre-and post-operation,and provide objective evaluation indicators of Achilles tendon.
