Comparison Of Post-Operative Healing Speed Of Achilles Tendon Rupture Immobilized With Cast And Spalk Based On Microscopic Images In Local Rabbits (Lepus Domestica)

Abstract

The Achilles tendon is the most common tendon to rupture. Immobilization after Achilles tendon rupture surgery is performed to produce functional recovery and shorten rehabilitation time. The aim of this study was to determine the comparison of the speed of healing after surgery for Achilles tendon ruptures immobilized with plaster and plaster based on microscopic images in local rabbits (Lepus domestica). This research method is an experimental type of research with a post-test only control group design. Thirty mice aged 3-4 months were selected for treatment of Achilles tendon injuries in the right caudal extremity. After sewing the ends of the AT together with the modified “Kessler” method (Prolene 5–0). The skin incision is cut and sutured with 1-0 thread. Rabbits were divided into two immobilization methods (cast and spalk groups), as well as controls to compare cell morphology, collagen arrangement, cellular substance, and vascularization on the tendon healing process. The study was carried out for 21 days with observations on days 7, 14, and 21. Day 7 showed plaster immobilization of 5.87 ± 0.76 compared to spalk 5.73 ± 0.31 and control 4.60 ± 0.72. On day 14, it was seen that the plaster immobilization treatment was still the highest at 9.47 ± 0.31 compared to spalk 9.33 ± 0.31 and control 6.20 ± 0.35. On day 21, the average of the cast immobilization treatment was the highest at 10.33 ± 0.31 compared to spalk 10.07 ± 0.12 and control 9.47 ± 0.50. The results of this study showed that cast and spalk did not have a significant effect (P>0.05) on the histology of archiles tendon rupture, only in the initial phase, namely cell morphology, which had a significant difference in the installation of cast and splint immobilization devices.
