Fig. 2From: Comparison of cortical versus cancellous bone fixation in tendon-to-bone healing with a rat trans-calcaneal suture model for Achilles tendon sleeve avulsionSurgical procedure of the cortical fixation and the cancellous fixation between the Achilles tendon and calcaneus. A The native rat Achilles tendon. B The Achilles tendon was fixed to the cortical bone through two drill tunnels with the suture in the cortical group. C The Achilles tendon was fixed to the cancellous bone within a bone hole in the cancellous group. Cor. fixation: the controlled cortical group; Can. fixation: the cancellous groupBack to article page
