Anatomic and reverse shoulder prostheses in fracture sequelae of the humeral head

Abstract

The differential use of anatomic and reversed shoulder prostheses in secondary fracture treatment leads to an improvement in postoperative results. In fracture sequelae types 1 and 2, the anatomic prosthesis is a better choice. However, in fracture sequelae types 3 and 4 with severe deformities, the reversed prosthesis is clearly superior to the anatomic prosthesis.

Treatment of fracture sequelae of the proximal humerus: comparison of hemiarthroplasty and reverse total shoulder arthroplasty

“…However, the results of shoulder arthroplasty for FS may not be comparable to those for acute fractures. It was observed that the use of shoulder arthroplasty for FS elicited worst outcomes compared to other indications [5,12,15,31]. The comparison of outcomes in the treatment of FS between HA and RSA has not been previously reported, to the best of our knowledge.…”

“…The comparison of outcomes in the treatment of FS between HA and RSA has not been previously reported, to the best of our knowledge. Only Kiliç et al compared the anatomic (including HA and total shoulder arthroplasty) and RSA in FS [15]. The researchers implanted 36 HA in FS mainly types I and II, and 19 RSA in FS mainly types III and IV.…”

“…There are several studies comparing anatomic and RSA for the treatment of acute PHF [6,8,13,24]. However, the comparison of both types of prostheses for FS is very limited [15].…”

Management of proximal humerus fractures utilizing reverse total shoulder arthroplasty

“…In type 3 (surgical neck nonunion) and 4 (severe tuberosity malunion) sequelae, RTSA has been shown to improve functional scores. In a study by Kilic et al, the authors reported a significant increase in Constant scores (9.0 preoperatively to 47.5 postoperatively) for 17 patients with type 3 and 4 fracture sequelae [29]. A similar study by Willis et al investigated the use of RTSA in 16 patients with proximal humeral malunions [30].…”

Humeral Morphometrics: A Study in Eastern Indian Population

“…Since these prostheses are also used in populations of different ethnic and morphological structure, there appears a general incompatibility between the features of the prosthesis and the morphometric data of the population where they are used. As a result, additional efforts are being given during the replacement surgeries like curettage of the bone structure and associated loss of tissue develops, which has a negative effect on clinical progress and success [21,22]. These problems could be overcome by manufacturing prostheses as per the requirements of various ethnic and racial groups throughout the whole world.…”
