Thereafter clinical evaluation of those casts was undertaken in twelve bovine fracture cases (Group- I: 6 cases of tibial fracture treated with PW:TFC) and (Group- II: 6 cases of metacarpal fracture treated with PVC:RWPC). Clinical relevance of those casts like ease of application, conformability and strength development was also evaluated. Compressive stress of the transfixation cast (PW:TFC) and rain water pipe cast (PVC:RWPC) were found to be (Mean ±SE) 3.482 ±0.182 N/mm2 and 12.599 ±0.619 N/mm2, respectively.. Bending stress of the transfixation cast (PW:TFC) and rain water pipe cast (PVC:RWPC) were found to be (Mean ±SE) 5.534 ±0.233 N/mm2 and (Mean ±SE) 3.013 ±0.078 N/mm2. PVC:RWPC found superior than PW:TFC as per as radiolucency test is concern. All the clinical parameters like heart rate, rectal temperature, respiration rate and inflammatory signs of pain and swelling were also recorded before and after the fracture fixation. The radiographs were taken to evaluate the success of fracture reduction and fixation. Serum alkaline phosphatase activity was measured at different intervals during the convalescent period of bone healing.ennullThesis
