Modified minimally invasive approach and intra-osseous portal for three-part proximal humeral fractures: a comparative study

Proximal humeral fracture is a common fracture. Different approaches have been utilized in the surgical intervention of three-part fractures. Our study is to evaluate the clinical outcomes and effectiveness of a modified anterolateral approach and intra-osseous portal in minimally invasive treatment for three-part proximal humeral fractures in comparison to the traditional deltopectoral approach. From March 2015 to September 2016, 13 patients with three-part proximal humeral fractures were treated with internal fixation through the modified anterolateral minimally invasive approach (MIPO). These cases were compared to 20 additional cases using the deltopectoral approach (DP). Clinical and radiographic evaluations were performed, including the constant score (CS) and range of motion in abduction, flexion/extension and external/internal rotation. Complications were recorded as well. All patients were followed up for a mean time of 12.12 ± 4.01 months. At the latest follow-up, no significant differences (p
