Introduction Reverse total shoulder arthroplasty (RTSA) procedures are becoming increasingly more common. While the main complications are known, the management of clavicle fractures in patients with an ipsilateral RTSA is not well described. There are three case studies that document clavicular stress fractures following RTSA with an atraumatic etiology, and to our knowledge, no studies have described a traumatic clavicular fracture following RTSA. Case We describe the case of a 75-year-old woman with a traumatic clavicle fracture five years after RTSA for rotator cuff tear arthropathy. With minimal pain and subjective symptoms initially, the patient wished to pursue non-operative treatment. However, she eventually developed a painful non-union and pseudoparalysis of the shoulder with serial radiographs demonstrating progressive superior scapular tilting and scapular notching. Subsequent open reduction internal fixation of her clavicle fracture significantly improved her pain and function. Conclusion We report a traumatic clavicle fracture in the setting of RTSA that not only failed to heal but also resulted in scapular notching and shoulder pseudoparalysis that was improved with surgical stabilization of the fracture. It is possible that the setting of a semi-constrained RTSA, the resulting biomechanical imbalance may predispose to impaired fracture healing and non-union of the clavicle fracture.

Reverse Total Shoulder

Scapular notching is a complication of reverse total shoulder arthroplasty (rTSA) that results in bone loss on the lateral border of the scapula. Notching has been reported in up to 86% of patients at 5 year follow-up [1], and is graded 1–4 as a function of progressive bone loss [2]. Notching may arise from impingement, erosion, periprosthetic osteolysis, stress shielding or a combination of these [1]. Glenosphere position can mitigate notching by limiting hardware impingement [3–5], but may increase the forces required to abduct the arm [6]. Clinicians might optimize patient range of motion and function via implant placement if susceptibility to notching was known a-priori.

Background: To evaluate clinical and radiological outcomes of bony increased offset-reverse total shoulder arthroplasty (BIO-RSA) in the Asian population at mid-term follow-up.Methods: From June 2012 to August 2017 at a single center, 43 patients underwent BIO-RSA, and 38 patients with a minimum of 2 years of follow-up were enrolled. We evaluated the preoperative and postoperative clinical outcomes, radiological outcomes (notching and loosening), and complications of BIO-RSA at the last follow-up. In addition, we divided these patients into notching and not-notching groups and compared the demographics, preoperative, and postoperative characteristics of patients between the two groups.Results: Visual analog scale, American Shoulder and Elbow Surgeons, University of California-Los Angeles, and Simple Shoulder Test scores improved significantly from preoperative (average: 5, 39.43, 16.22, 3.94) to postoperative (average: 1.71, 78.91, 28.34, 7.8; p<0.05) outcomes. All range of motion except internal rotation improved significantly at the final follow-up (p<0.05), and the bone graft was well-incorporated with the native glenoid in all patients (100%). However, scapular notching was observed in 20/38 patients (53%). In the comparison between notching and not-notching groups (18 vs. 20 patients), there were no significant differences in demographics, radiological parameters, and clinical outcomes except acromion-greater tuberosity (AT) distance (p=0.003). Intraoperative complications were three metaphyseal fractures and one inferior screw malposition. Postoperative complications included one heterotopic ossification, one scapula neck stress fracture, one humeral stem loosening, and one late infection.Conclusions: BIO-RSA resulted in improved clinical outcomes at mid-term follow-up in the Asian population. Although better cosmesis and advantages of glenoid lateralization were observed, we observed higher rates of scapular notching compared to previously reported rates in BIO-RSA studies. In addition, adequate glenoid lateralization with appropriate humeral lengthening (AT distance) might reduce scapular notching.

Aims This systematic review asked which patterns of complications are associated with the three reverse total shoulder arthroplasty (RTSA) prosthetic designs, as classified by Routman et al, in patients undergoing RTSA for the management of cuff tear arthropathy, massive cuff tear, osteoarthritis, and rheumatoid arthritis. The three implant design philosophies investigated were medial glenoid/medial humerus (MGMH), medial glenoid/lateral humerus (MGLH), and lateral glenoid/medial humerus (LGMH). Methods A systematic review of the literature was performed via a search of MEDLINE and Embase. Two reviewers extracted data on complication occurrence and patient-reported outcome measures (PROMs). Meta-analysis was conducted on the reported proportion of complications, weighted by sample size, and PROMs were pooled using the reported standardized mean difference (SMD). Quality of methodology was assessed using Wylde’s non-summative four-point system. The study was registered with PROSPERO (CRD42020193041). Results A total of 42 studies met the inclusion and exclusion criteria. Rates of scapular notching were found to be significantly higher in MGMH implants (52% (95% confidence interval (CI) 40 to 63)) compared with MGLH ((18% (95% CI 6 to 34)) and LGMH (12% (95% CI 3 to 26)). Higher rates of glenoid loosening were seen in MGMH implants (6% (95% CI 3 to 10)) than in MGLH implants (0% (95% CI 0 to 2)). However, strength of evidence for this finding was low. No significant differences were identified in any other complication, and there were no significant differences observed in PROMs between implant philosophies. Conclusion This systematic review has found significant improvement in PROMS and low complication rates across the implant philosophies studied. Scapular notching was the only complication found definitely to have significantly higher prevalence with the MGMH implant design.

Reverse Total Shoulder

Reverse total shoulder arthroplasty (rTSA) is used to improve pain and function in arthritic, rotator cuff deficient shoulders. Surgical intervention is considered successful if range of motion and stability of the joint is maximized and force to abduct the arm is minimized. Implant hardware positioning may affect these outcome measures.
