Comparative study of stainless steel and titanium limited contact-dynamic compression plate application in the fractures of radius and ulna

Abstract

Background: Stainless steel and titanium are two different metals with different mechanical and metallurgical properties. Stainless steel is twice more stiffer than titanium. Internal fixation of fractures with stainless steel plates is likely to produce more rigid fixation than titanium plates. Hence, stainless steel plate fixation is likely to produce healing of fracture site with minimum callus/primary healing. This study analyzes whether these properties of the metals influence the healing of the fractures and their outcomes. Materials and Methods: Thirty-five cases of fractures of radius and ulna were treated by internal fixation using stainless steel limited contact-dynamic compression plate (LC-DCP) (Group I) in 17 patients and titanium LC-DCP (Group II) in 18 patients. Follow-up was done at 6 weeks, 12 weeks, 6 months, and 1 year for clinical and radiological healing and complications. Results: All the fractures united in time. 10 (62.5%) patients in Group I and 9 (56.2%) patients in Group II showed primary union and 6 (37.5%) patients in Group I and 7 (43.2%) patients in Group II showed union with callus formation. No complications were observed. Conclusion: Stainless steel and titanium are two different metals with different mechanical and metallurgical properties. However, fixation of fractures with these metals failed to show the difference in the patterns of fracture healing.
