Reverse Total Shoulder

Purpose: the aim of this study was to analyze complications of reverse total shoulder arthroplasty (RTSA) used to treat different shoulder diseases. Methods: from March 2000 to March 2013, 195 RTSA were implanted by the senior Author. The indications for reverse prosthesis surgery were secondary osteoarthritis (OA) in 49 cases, irreparable rotator cuff tear (RCT) in 48 cases, and complex humeral fractures in 75 cases, while 19 were patients requiring surgical revision for first prosthesis implant. We used different prostheses with different designs. Results: the clinical and radiological results of all the patients were analyzed retrospectively at an average follow-up of 7 years. The cases were divided into four groups on the basis of the diagnosis and complications were classified as perioperative, postoperative, or late. The mean total Constant score improved from 28 to 69 points in the OA group; from 21 to 70.8 points in the irreparable RCT group, to 76.4 in the fracture group, and from 16.6 to 59.8 points in the revision group. Scapular notching was observed in 59 cases (30.2%). Thirty-three other complications (16.9%) were observed, namely: hematomas (n=3), instability of the humeral component (n=1), scapular spine fractures (n=2), ulnar nerve deficit (n=2), long thoracic nerve palsy (n=2), deep infections (n=2), periprosthetic fractures (n=6), glenoid fractures (n=2), implant loosening (n=2), anterior deltoid muscle deficiency (n=2) and periarticular heterotopic calcifications (n=9). Conclusions: the rates of complications, especially fractures, reported in the present study were lower than those reported in the current literature. Level of evidence: Level IV, therapeutic case series.

Background Thus, the purpose of the present study was to (1) characterize common postoperative complications and (2) quantify the rates of revision in patients undergoing hemiarthroplasty to reverse total shoulder arthroplasty revisional surgery. We hypothesize that hardware loosenings will be the most common complication to occur in the sample, with the humeral component being the most common loosening. Methods This systematic review adhered to PRISMA reporting guideline. For our inclusion criteria, we included any study that contained intraoperative and/or postoperative complication data, and revision rates on patients who had undergone revision reverse total shoulder arthroplasty due to a failed hemiarthroplasty. Complications include neurologic injury, deep surgical site infections, hardware loosening/prosthetic instability, and postoperative fractures (acromion, glenoid, and humeral fractures). Results The study contained 22 studies that assessed complications from shoulders that had revision reverse total shoulder arthroplasty from a hemiarthroplasty, with a total sample of 925 shoulders. We found that the most common complication to occur was hardware loosenings (5.3%), and of the hardware loosenings, humeral loosenings (3.8%) were the most common. The revision rate was found to be 10.7%. Conclusion This systematic review found that revision reverse total shoulder arthroplasty for failed hemiarthroplasty has a high overall complication and reintervention rates, specifically for hardware loosening and revision rates.

Reverse Total Shoulder

Background In a reverse total shoulder arthroplasty, the altered glenohumeral joint center of rotation subjects the glenoid baseplate to increased shear forces and potential loosening. Methods This study examined glenoid baseplate micromotion and initial fixation strength with the application of direct shear force in a Sawbone model. The reverse total shoulder arthroplasty systems examined were the DJO Reverse® Shoulder Prosthesis, the Exactech Equinoxe® Reverse System, and the Tornier AequalisTM Reverse Shoulder Prosthesis. Specimens were cyclically tested with increasing shear loads until 150 µm of displacement between the implant and glenoid was achieved, and subsequently until failure, classified as either 1 cm of implant/glenoid displacement or fracture. Results The average load withstood for the 150 µm threshold for DJO, Tornier, and Exactech was 460 ± 88 N, 525 ± 100 N, and 585 ± 160 N, respectively. The average total load at device failure for DJO, Tornier, and Exactech was 980 ± 260 N, 1260 ± 120 N, and 1350 ± 230 N, respectively. Discussion The Exactech implant design trended toward requiring more load to induce micromotion at each threshold and to induce device failure, most commonly seen as inferior screw pull out. This study proposes design features that may enhance fixation and suggests little risk of initial micromotion or failure during initial post-operative recovery.
