Summary
Anterior humeral bride plating using MIPO technique yields high rates of union, minimal biological disruption of the soft tissue envelope, and better cosmesis, along with a fast and good functional recovery of patients with humeral shaft fractures
Abstract
Introduction
Recently, surgical treatment of diaphyseal humeral fractures has gained importance worldwide. Although, open reduction and internal fixation, with a plate and screws, still remains as the gold standard, however there have been increasingly concerns with the dissection of soft tissues around the fracture site. The anterior bridge plating (MIPO) technique for the treatment of these fractures has gained remarkable popularity amidst orthopedic surgeons, globally.
Materials & methods: Prospective study of 43 adult patients, with a humeral diaphyseal fracture, treated by anterior bridge plating (MIPO) technique. Patients with closed, displaced diaphyseal fracture of the humerus, between 15 to 65 years, were included in this study. Patients with open fractures, associated neurovascular injury, and with history of previous infection in the humerus or elbow were excluded from this study Patients were followed clinically and radiographically.
Results
Out of 40 patients, union was observed in 38 (95%) fractures. Two fractures did not unite at 6 months follow up, and required bone grafting as a secondary procedure for union. The time taken for radiographic union was found to be less than 12 weeks in 3 fractures, between 12-16 weeks in 33fractures, and higher than 16 weeks in 2fractures. On determining the final shoulder functional outcome, 33 patients (82.5%) had excellent result, and 7 patients (17.5%) had good shoulder function, on UCLA score. With regard to the final elbow function, 31 patients (77.5%) had an excellent outcome, 6 patients (15%) had a good outcome, 2 patients (5%) had a fair outcome, and 1 patient (2.5%) had a poor outcome.
Conclusion
Anterior humeral bride plating using MIPO technique yields high rates of union, minimal biological disruption of the soft tissue envelope, and better cosmesis, along with a fast and good functional recovery of patients with humeral shaft fractures.
