Functional outcome of modified technique of intramedullary fixation of diaphyseal humeral fractures

Abstract

Background:The aim of this study was to evaluate the functional outcomes with intramedullary fixation using flexible nails and to follow up for any other complications. Methods: Study was a prospective study in Lata Mangeshkar Hospital, Nagpur during 2014 to 2016. All the patients enrolled in the study were briefed about the nature of the study. All cases in this series were operated by combined antegrade and retrograde approach. Results: Total of 30 patients of closed diaphyseal humeral fractures was studied. Maximum i.e., 16 (53.33%) were in the age range of 21-40 years, followed by 10 (33.33%) patients in the range of 41-60 years. 21 (70%) cases had fracture union between 10-16 weeks with a score of 8 points, followed by 8 (26.67%) patients with fracture union duration of less than 10 weeks with a score of 10 points. Only one of the patients landed up with non-union. The mean functional score of patients at 3rd month was 64.03±4.99, 9th month was 73.46±2.56. 86.66% patients had good to fair outcome, 3.33% patient each had excellent and poor outcome. Conclusions: Comparing results of our study with other studies, we found that our results are almost comparable but not better than open reduction and plating. Complications encountered in our series are comparatively less compared to those encountered during interlock nailing. The trauma to rotator cuff is minimum and this method is good alternative method. Thus, multiple nailing gives better functional outcomes as compared to locked nail.
