Comparison of clinical, biomechanical, and histopathological effects of various suture techniques on repair of tendon rupture by using autograft

Abstract Introduction: The purpose of this study was to compare the effectiveness of four different suture techniques in the treatment of experimentally modelled tendon injuries with tissue loss with autograft and grafting applications in rabbits. Material and Methods: The study was performed on 30 male mature (2-year-old) New Zealand rabbits with mean body weight of 3.1 kg, divided into three equal groups. A graft measuring 1 cm in length was collected from the m. tibialis cranialis of each rabbit under general anaesthesia. The graft collected from the right tendon was transplanted into the left tendon, and the graft from the left tendon was transplanted into the right tendon. In all groups, a simple interrupted suture was placed on the left tendon as control, a Bunnell-Mayer suture was placed on the right tendon in group I, a Locking-Loop suture in group II, and a Horizontal U suture in group III. Both hindlimbs were bandaged for four weeks. The tendons were assessed biomechanically and histopathologically. Results: According to the results of the tensile testing, the maximum durability of the techniques ranked as follows: Bunnell-Mayer, Horizontal U, Locking-Loop, and control groups. Conclusion: The use of autografts was a good alternative for the treatment of tendon ruptures with tissue loss. Furthermore, even though there were no clinical or histopathological differences, the suture technique can be chosen based on the results of the tensile test.

Effects of Intrathecal Administration of Ketamine HCl in Young Calves: A Clinical Trial

Abstract The purpose of the study was to investigate the clinical, biochemical, and cardiovascular effects of intrathecal (IT) administration of ketamine HCl in calves. The study was performed on seven Simmental and three Montofon calves, 1.70 ± 1.16 weeks old, weighing approximately 37 kg, undergoing surgical procedures including femur fracture repair (one case), atresia anus (five cases), prolapsed rectum (one case), suturing on rear limbs (two cases), and urethrostomy (one case). After administering IT ketamine HCl at a dose of 3 mg/kg to all calves, the level and depth of the anaesthesia was checked with a pin-prick test. Each animal was monitored by recording heart rate, arterial blood pressure, respiratory rates, and rectal temperature. Furthermore, certain biochemical parameters, blood gases, oxygen-total haemoglobin, and electrolyte levels were measured. All data were statistically evaluated using Minitab 16 software. Anaesthesia occurred in all calves at an average of 5.00 ± 1.41 min (range: 3-7) and continued for an average of 61.4 ± 40 min (range: 55-70). Sufficient anaesthesia was achieved in all animals for the required operations, and no complications occurred with regard to clinical and haemodynamic measurements. We concluded that in calves, which are not deemed suitable for administration of local anaesthetic via IT due to certain side effects, sufficient anaesthesia can be provided with ketamine by the same method for operations performed in the perineal area and hind extremities, and that this could be a good alternative for anaesthesia under field conditions.
