Conditions

Potential damage to the deltoid muscle insertion caused by blunt advancement of a minimally invasive plate along the lateral aspect of the humerus to bridge a fracture Surgery

Interventions

The charts of all patients with MILPOH for diaphyseal fractures of the humerus with extension into the proximal metaphysis, operated at our institution between 03/2017 and 08/2020 were reviewed. Only

Design outcomes

Primary

Measure	Time frame
All measured at least 1 year postoperatively, time range 12-48 months: 1. Abduction and flexion strength of the deltoid muscle at 30°, 60°, 90° of the affected and uninjured side, measured using an electronic isometric strength dynamometer (IsoForceControl EVO2; Medical Device Solutions AG, Oberburg, Switzerland). 2. Imaging of the deltoid muscle and its distal insertion performed by MR imaging (1.5T MRI scanner [Ingenia, Philips Healthcare, Best, the Netherlands])	—

Secondary

Measure	Time frame
All measured at least 1 year postoperatively, time range 12-48 months: 1. Overall shoulder function measured using the Constant-Murley Score (CMS) and gender- and age-adapted CMS 2. Shoulder pain and function measured using the Oxford Shoulder Score (OSS) 3. Upper-extremity disability and symptoms measured using the Disabilities for the Arm, Shoulder, and Hand (DASH) outcome measure 4. Patient's self-rated health measured using EQ-5D-5L visual analogue score (VAS) 5. Mobility, self-care, usual activities, pain and anxiety/depression measured using EQ-5D-5L	—
