Dynamic compression plating with interlocking nailing for fracture shaft of humerus in adult: A prospective study

Background: In orthopaedics, a humerus fracture is a frequent yet difficult to treat problem. Unless complicated, these are normally treated non-operatively (with a hanging arm cast, U cast, or U slab). Complete union is not always required since the bone has a dense covering of muscles and blood vessels. The goal of this study was to see if there was a difference between dynamic compression plating (DCP) and intramedullary interlocking nailing in diaphyseal humeral fractures in adults. Methods: It was a prospective study undertaken at MGM Medical College and L.S.K. Hospital in Kishanganj, Bihar, in the department of orthopaedics. During the study period of November 2020 to September 2021, a total of 40 cases were enrolled. The participants in the study were randomly assigned to one of two groups. One closed reduction and internal fixation with antegrade intramedullary interlocking nail-group, and one open reduction and internal fixation with dynamic compression plating-group. Results: We found that the final outcome in between the groups, comparison of DASH score, maximum number of excellent cases were Dynamic compression plating group. i.e. 80.0%, good-13.3%, Fair was 6.7% respectively. In another Interlocking nailing group excellent cases were found 26.7%, good-33.3%, fair- 26.7% and poor was 13.3% respectively. We have found statistically significant p value -0.028. Conclusion: There appears to be a substantial difference in radiological union or rate of union between the two groups; nonetheless, based on complications and functional results, Dynamic compression plating is a good fixation method
