【 摘 要 】

Category:HindfootIntroduction/Purpose:Percutaneous Achilles tendon lengthening (TAL) is a common procedure used to address equinus contracture of the foot. A triple hemisection technique has become popular due to its ease and efficiency. Several studies evaluate the surgical outcomes of this procedure, but currently, descriptive anatomical studies are lacking. The objective of the study was to evaluate the accuracy of performing Achilles tendon percutaneous hemisections, the amount of tendon excursion in the tensile gaps of the cuts after forced dorsiflexion and the improvement in the range of motion for dorsiflexion of the ankle joint.Methods:Ten fresh-frozen above-knee cadaveric specimens were used. A percutaneous triple hemisection of theAchilles tendon (proximal, intermediate, and distal) was performed. Maximum ankle dorsiflexion was evaluated pre- and postprocedure with a digital goniometer. After proper dissection, the relative width of the cuts was noted. Followingforced ankle dorsiflexion, displac...
