A Comparative Study of Dynamic Compression Plating (DCP) and Intramedullary Interlocking Nailing in Diaphyseal Fractures of the Humerus (Code-T0045)

Introduction: Diaphyseal fractures of the humerus are common orthopedic injuries that require effective surgical intervention to restore function and ensure proper healing. Dynamic Compression Plating (DCP) and Intramedullary Interlocking Nailing (IMN) are two popular surgical techniques used for the fixation of these fractures. The choice of technique often depends on factors such as fracture type, patient condition, and surgeon expertise.

Aims and Objective: The main aim of this study is to compare the outcomes of each method of fixation (dynamic compression plating and interlocking nailing) for the humerus diaphyseal fractures and to analyse and observe statistically significant difference in the results of these two procedures and give a conclusion which method is superior overall considering complications and functional outcomes.

Methods: This prospective study included 80 patients with diaphyseal humeral fractures, who were randomly assigned to undergo either DCP or IMN fixation. Clinical evaluation was performed at regular intervals, assessing union time, functional outcomes using the Constant-Murley Shoulder Score, and complications such as infection, non-union, or malunion.

Results: Both groups achieved a similar fracture union rate, but the IMN group had a significantly shorter healing time (average 10 weeks) compared to the DCP group (average 12 weeks). The complication rate was slightly higher in the DCP group, particularly for wound infections and malunion. The functional outcomes were comparable between the two groups, with both showing good to excellent results in the majority of patients.

Conclusion: Both Dynamic Compression Plating and Intramedullary Interlocking Nailing are effective for managing diaphyseal fractures of the humerus. IMN may offer faster healing times with a similar functional outcome, making it a preferable option for many cases.
