The effect of tramadole hcl and paracetamol on fracture healing in rat tibia model

In our research, we aim to study the effects of combined usage of tramadole HCl + paracetamol on rat tibia fracture model. In our study, 60 Wistar-Albino type male rats, weighted at 300-350 g., were divided as “control” and “test” ( tramadole HCl + paracetamol) groups Under general anesthesia, standard closed fractures were created on right tibias of all rats using blunt ended needle holder with three point principle and then closed reduction and fixing with intramedullary nail (0.7 mm) were provided. After fracture treatment of 30 rats in the test group, starting at the same day, 40mg/kg/day tramadole HCL was introduced as daily intermuscular dosage until they were sacrificed. Rats were sacrificed after the fractures as groups of 10 individuals at 2nd, 4th and 6th weeks. Healing fractured tibias were examined mechanically, radiologically, histopathologically. Results: No positive or negative radiological, biochemical and histological effect was detected after the long duration of tramadole HCL + paracetamol usage, starting from the first day and reaching to 6 weeks, in healing process of closed tibia fractures created and fixed with IM nails in rats. Considering the negative effects of NSAIDs on fracture healing, we think that tramadole HCl + paracetamol combination is a safe option in postoperative pain treatment after fracture
