Abstract
Objectives: The primary objective of this systematic review was to evaluate pain relief and shoulder functional outcome following reverse shoulder arthroplasty for three- and four-part proximal humerus fractures in patients over the age of 60 years. The secondary objective was to assess the clinical end radiological complications following this procedure for this indication.Methods: Studies were identified using a MEDLINE search for relevant articles on 20th May 2019. The key terms ‘reverse shoulder arthroplasty’ and ‘proximal humerus fracture’ were used.Results: Five retrospective case-series fully met the eligibility criteria. No randomized controlled trials or meta-analyses were found. All of the studies agreed that reverse shoulder arthroplasty was able to offer good pain relief, function end range of forward flexion (FF), and abduction (Abd.). Restrictions in shoulder rotation have to be fully addressed. The rate of major complications, reduction in functional outcome, and development of scapular notching with time was a concern.Conclusions: Reverse shoulder arthroplasty for comminuted proximal humerus fractures has increased over the past several years, yet the published data evaluating the surgical outcome is limited. Large well-designed prospective randomized controlled trials are needed for comparing the various treatment options, in order to ensure that these patients receive the best treatment available.

Summary
Proximal humerus fractures are the second most common upper extremity fracture and the third most common fracture affecting patients over the age of 65, following hip and distal radius fractures [1]. They usually result from simple falls onto the outstretched limb or the shoulder itself. The optimal management of complex three- and four-part displaced fractures of the proximal humerus in elderly patients with poor bone quality remains controversial. These pose a challenge to every orthopedic surgeon as there is a wide variety of surgical options available as well as nonoperative management being advocated in some centers
