双蒂腓肠肌皮瓣修复跟腱复合缺损的改进及其解剖学依据

目的改进双蒂腓肠肌皮瓣下滑术式,细化其修复跟腱复合组织缺损适应证,减少供区创伤。方法0侧成人下肢标本,模拟只切断比目鱼肌近端附着点、保留跟腱远端完整性的双蒂腓肠肌V-Y推进皮瓣,测定膝关节不同屈曲角度下皮瓣下滑的距离。结果在膝关节屈曲0°、30°、60°、90°时,上述方法后双蒂腓肠肌皮瓣下滑的平均距离分别为(13.83±5.31)mm、(25.00±2.83)mm、(32.67±4.41)mm、(39.50±4.85)mm。结论双蒂腓肠肌V-Y下滑术式中只切断比目鱼肌近端附着点后重建,保留跟腱远端完整性的这一改进在解剖学上是可行的,适用于40mm以内的成人跟腱复合组织缺损。

Bi-pedicled gastrocnemius flap for repairing the composite defect of Achilles tendon: the modifications and anatomy

Objective:To modify the sliding bi-pedicled gastrocnemius flap technique,quantify its indications for repairing the composite Achilles tendon defects,and lessen the donor site morbidity. Methods: Thirty adult specimens of the lower extremity were used. The simulations of the bi-pedicaled gastrocnemius flap were made on these specimens with the detachment of the proximal soleus and the preservation of the integrity of Achilles tendon. The sliding distances of this flap were measured under different degrees o...
