Open Reduction and Internal Fixation With Proximal Humerus Locking Plate, Screws, and Fibular Strut Graft: An Alternative to Shoulder Arthroplasty and Solution to Medial Instability and Varus Collapse in Comminuted Proximal Humerus Fractures

Abstract

Fractures of the proximal humerus are a frequent ailment in the senior population. One concern with such a case that presented in our emergency room was the risk of varus collapse following open reduction and internal fixation (ORIF) in a patient with marked calcar comminution. The surgical method used in this case of a NEER four-part fracture with medial column instability proved effective in terms of good surgery outcome, patient satisfaction, good range of motion, and low or no pain at post-surgical follow-ups. ORIF with a locking plate and fibular strut graft proved to be a viable alternative to solo plating or shoulder arthroplasty. We conducted upper extremity patient-reported functional outcome scales (ASES, CONSTANT, and Neer's "limited goals") with this particular patient. At the last visit, two years after the first surgical intervention, the patient had a normal range of motion, was pain-free, and was generally satisfied with the results of the surgery. We concluded that ORIF of the proximal humerus with locking plate and fibular strut graft was, in our case, a good solution for preventing varus malalignment in a patient with severe comminution of medial calcar.
