Abstract.Background: Fracture of the clavicle is a frequently seen injury which represents about 10-15% of all fractures in adults. About 80% of all clavicular fractures involve the middle third of the bone. The present study was undertaken to study the comparison between intramedullary nailing by TEN-titanium elastic nail and pre-contoured plates for the fracture of the middle third clavicle. Methods: A total of 40 unilateral displaced simple mid-shaft clavicular fractures operated between Jan. 2013 to Jan. 2015 were included in this study. Patients fitting into the inclusion criteria were selected. 20 patients were treated with TEN and 20 by pre-contoured plates, comparison was made and outcome was measured by the Constant score, union rate and difference in clavicular length after fracture union. Results: During analysis, in 20 patients treated by TEN, excellent results were observed in 17 patients (85%) and 3 patients (15%) with good results and in the plating group, 16 patients (80%) had excellent results, 3 patients (15%) had good results and 1 patient (5%) had fair result. Conclusion: The use of minimally invasive TENS for fixation of displaced midshaft clavicle fractures has faster fracture healing, lesser morbidity, better cosmetic results, easier implant removal and fewer complications, with restoration of clavicluar length in simple fractures. Although for comminuted fractures plating remains the procedure of choice.
