Multifocal Humeral Fractures: Clinical Results, Functional Outcomes and Flowchart of Surgical Treatment.

Aim and objective: Multifocal fractures of the humerus are rare. The aim of our study is to evaluate the effectiveness of surgical treatment and propose a modification to the Maresca-Pascarella classification. A flowchart for surgical treatment is provided.

Materials and methods: Thirty-one patients with multifocal humeral fractures were treated and evaluated. The Maresca-Pascarella classification was used. All were treated using with either plates and screws, external fixation or intramedullary nailing. Functional outcomes were evaluated using the QuickDASH test, the University of California - Los Angeles (UCLA) shoulder score and the Mayo elbow performance score (MEPS).

Results: There were 12 Type A, 17 Type B, 1 Type C and 1 of combined fractures of the proximal and distal epiphysis. Of the 31 patients, 5 were lost to the follow-up (FU), 1 died of pulmonary embolism (PE) and the remaining 25 had a mean FU of 19.8 (7-35) months. Three patients had radial nerve damage and 1 went to a non-union that required further surgical intervention. The mean QuickDASH score was 15.7, the average UCLA shoulder score was 26.3 and the mean MEPS elbow score resulted to be 83.0.

Conclusion: Although multifocal fractures are severe injuries, patients are able to recover good functionality if treated judiciously.

Clinical significance: We proposed a standardised surgical approach based on the fracture characteristics, site and a modified Maresca-Pascarella classification.
