Advanced glenohumeral osteoarthritis can transform glenoid morphology and, in some cases, is found in association with severe glenoid retroversion. The associated glenoid retroversion leads to difficulty in fixation of the glenoid component in reverse total shoulder arthroplasty. In the context of extreme glenoid wear, structural grafts can be used to restore glenoid volume and version in order for the glenoid component of the reverse total shoulder arthroplasty to be more easily implanted. Nevertheless, literature regarding structural grafts remains limited, with optimal graft choice and technique still controversial at best...

BACKGROUND: An understanding of the substantial clinical benefit (SCB) after total shoulder arthroplasty (TSA) may help to gauge a minimum threshold beyond which a patient perceives his or her outcome as being substantially better. This study quantifies SCB for 7 outcome metrics and active motion measurements after shoulder arthroplasty and determines how these values vary based on prosthesis type, patient age at surgery, sex, and length of follow-up. METHODS: A total of 1,568 shoulder arthroplasties with 2-year minimum follow-up were performed by 13 shoulder surgeons and enrolled in a multicenter registry...

BACKGROUND: It is common for patients to require staged bilateral shoulder arthroplasties. There is a unique cohort of patients who require an anatomic total shoulder arthroplasty (TSA) and a contralateral reverse shoulder arthroplasty (RSA). This study compared the outcomes of patients with a TSA in 1 shoulder and an RSA in the contralateral shoulder. METHODS: Our institutional database was queried to identify all patients with a TSA and a contralateral RSA. Data collection included patient demographics, preoperative and latest follow-up shoulder range of motion, radiographic analysis, and postoperative complications...

BACKGROUND: The treatment of periprosthetic joint infection (PJI) of the shoulder with two-stage revision arthroplasty using an antibiotic-loaded cement spacer is established strategy, but there is sparse information regarding the likelihood of infection control and restoration of shoulder. QUESTIONS/PURPOSE: (1) What is the likelihood of infection control after two-stage revision using an antibiotic cement spacer for patients with PJI of the shoulder? (2) What are the improvements in Constant and Murley scores at 2 years after these staged revisions? PATIENTS AND METHODS: Between 2000 and 2013, we treated 48 patients with PJI of the shoulder using two-stage revision including an antibiotic-containing cement spacer during the first stage...

INTRODUCTION: Tuberosity healing is known to be one of the factors that increase functional outcome in Reverse Total Shoulder Arthroplasty (rTSA). In fragility fractures, tuberosity healing is difficult to be achieved. The fragment stability and bone-forming agent application become strategies to overcome this problem. The purpose of this study was to evaluate the benefit of teriparatide application to promote tuberosity union in rTSA on four-part proximal humeral fractures to achieve better functional outcome...

BACKGROUND: Although reverse total shoulder arthroplasty (RTSA) has been shown to reduce pain and to improve function in most patients, some still suffer from functional limitations. This study aimed to investigate the incidence of poor motion recovery after RTSA and to identify factors that may cause poor outcomes. METHODS: Seventy-six patients who underwent primary RTSA with a reverse-type Aequalis prosthesis (Tornier, Montbonnot, France) were allocated to a satisfactory or unsatisfactory group on the basis of their postoperative active anterior elevation...

BACKGROUND: The anterosuperior (AS) approach for reverse total shoulder arthroplasty (RTSA) has been reported as a risk factor for baseplate malposition because of potential difficulty in glenoid exposure. The objective of this study was to compare glenoid baseplate position between the AS and deltopectoral (DP) approaches in relation to the surgeon's experience and to evaluate the effect of placement on clinical outcomes. METHODS: There were 109 shoulders that underwent RTSA for cuff tear arthropathy or osteoarthritis with cuff tearing by a single surgeon...

CASE: A 53-year-old man presented with osteoarthritis (Walch biconcave [B2] glenoid retroversion, 22°; glenohumeral subluxation index, 65%) and a partial rupture of the supraspinatus tendon in the left shoulder. Following anatomic total joint replacement, he developed disabling recurrent posterior subluxation despite a stable prosthesis and a correctly centered glenoid head, as observed with postoperative radiography and computed tomography. In order to avoid bone loss and the complications associated with revision arthroplasty, we performed arthroscopic reefing of the posterior capsule as an experimental minimally invasive treatment...

CASE: A 41-year-old woman presented 5 years after glenohumeral arthrodesis. She experienced symptomatic relief following conversion to reverse total shoulder arthroplasty, regaining nearly full passive range of motion and >50% of normal active forward flexion, abduction, internal rotation, and external rotation. CONCLUSION: Conversion from glenohumeral arthrodesis to reverse total shoulder arthroplasty in a patient with a functioning deltoid and adequate bone stock may provide symptomatic relief and improved function in the setting of symptomatic glenohumeral arthrodesis refractory to conservative measures...

BACKGROUND: Implant registries have proved valuable in assessing the outcomes of arthroplasty procedures. Moreover, by identifying lesser quality implants they have indirectly improved the quality of care. The registry of prosthetic shoulder implants was established in 2008. METHODS: It records information on all types of primary and revision arthroplasty procedures involving the glenohumeral joint, including reverse and total arthroplasty, hemiarthroplasty, resurfacing, removal, and any other surgical procedures that are required to manage these patients...
