    BackgroundFractures of the proximal humerus are often associated with lesions of the long head of the biceps (LHB) tendon. This often leads to prolonged shoulder pain. Hence, many surgeons decide to perform a tenodesis of the LHB tendon simultaneous to ORIF. The purpose of this study was to evaluate the postoperative outcome after interlocking plate fixation and biceps tenodesis for treating proximal humerus fractures.Methods56 patients (38 females, 18 male) suffering from proximal humerus fractures who underwent surgery were retrospectively included. 26 of these 56 patients (19% Neer II, 38% Neer III, 43% Neer IV) were treated with simultaneous tenodesis of the LHB tendon when ORIF using interlocking plate fixation was performed. 30 patients (17% Neer II, 40% Neer III, 43% Neer IV) served as control group receiving only interlocking plate fixation. The patients were asked to complete the Munich Shoulder Questionnaire (MSQ) for evaluation of postoperative shoulder function. Results of the Disabilities of the Arm, Shoulder and Hand (DASH) Score and Shoulder Pain and Disability Index (SPADI) were calculated from the MSQ. Patients were clinically evaluated for a positive O'Brien test and Popeye sign.ResultsThe tenodesis group demonstrated significant superior outcome regarding the MSQ (mean 90.47 points vs. 79.41 points, p = 0.006), DASH Score (mean 4.2 points vs. 16.81 points, p = 0.017) and SPADI (mean 94.59 points vs. 83.56, p = 0.045). Flexion, external rotation and the capability of throwing a soft ball were significantly improved in the tenodesis group compared to the control group. The O'Brien test as indicator for lesions of the LHB was positive in fewer patients of the tenodesis group (2/26, vs. 21/30, p = 0.001). There was no significant difference of a positive Popeye Sign.ConclusionOur results show evidence of an improved shoulder function when a simultaneous tenodesis of the LHB tendon is performed during treatment of proximal humerus fractures using interlocking plate fixation.Copyright © 2019 Elsevier Ltd.
