Objective: To compare the outcome of intramedullary nailing versus dynamic compression plate for humerus shaft fractures.

Methodology:This comparative cross-sectional study was done in the Department of Orthopedic Surgery, Liaquat University of Medical & Health Sciences, Jamshoro. 33 patients were enrolled. In group A, the patients underwent surgery by using IMN. In group B, the patients underwent surgery by applying DCP. Operative time was noted. After discharge from hospital the patients were followed-up there for 22 weeks. After 22 weeks, patients underwent x-ray for confirmation of union and DASH score was noted in both groups.

Results: In this study in IMN group, union within 22 weeks of the patients was noted in 16(94.1%) patients whereas in DCP group the union within 22 weeks was noted in 15(93.8%) patients (p-value>0.99). In IMN& DCP group, mean operative time was 66.12±26.21&104.50±17.512 minutes respectively, (p-value<0.001). In IMN group, mean quick DASH score was 13.2±9.6 whereas in DCP group, mean quick DASH score was 15.6±9.8 (p-value=0.48)

Conclusion: In conclusion, both groups IMN & DCP for humerus shaft fracture are equally effective, however operative time was significantly shorter in IMN group as compared to DCP for humerus shaft fracture.
