Clavicle fractures account for 5{u2013}10% of all fractures and almost half of all shoulder girdle injuries. About 80% of these fractures affect the middle third of the clavicle.Intramedullary devices behave as internal splints that maintain alignment without rigid fixation. Intramedullary device has advantages of a smaller incision, less dissection, and load sharing fixation with relative stability that helps in callus formation. Forty patients between 18 and 60 years of age were included in this study. They were treated with EIN. Clinical and radiological assessments were performed at regular intervals to asses union, Constant Shoulder Score and DASH score were done to assess the functional outcome All fractures united and the mean duration of radiological union was 11.60 ± 4.76 (range, 5-20 weeks). There were no cases of malunion or non-union. The mean value of Constant score in comminuted type (84.88 ± 8.81) was less than that of simple and wedge (94.00 ± 5.39) (93.89 ± 6.38) respectively. The mean DASH score in comminuted type 12.19 ± 7.88 was higher than that of simple and wedge 1.7 ±2.29 (0.8-20), 5.29 ± 2.29(0.8-7.5) respectively
