Reverse Total Shoulder

Shoulder arthroplasty (SA) has improved significantly over the last twenty years. It offers the effective treatment for patients with severe shoulder dysfunctions. The indications for this procedure have recently expanded tremendously. However, the most common are glenohumeral osteoarthritis, inflammatory shoulder arthropathies, rotator cuff-tear arthropathy, complex fractures of the proximal humerus and osteonecrosis of a humeral head. There is range of the procedures, such as resurfacing of humeral head, anatomic total shoulder arthroplasty, hemiarthroplasty and reverse shoulder arthroplasty. All of them could significantly improve patients quality of life. The outcomes of the shoulder arthroplasty are very satisfying in terms of pain relief and considerable improvements in shoulder function as well as in motion. However, this procedure is not so popular as knee or hip arthroplasties. The reasons for this phenomenon are not clear. The complication rate is considerably low. The most common are periprosthetic fractures, infections, implant loosening and instability. The reasonable solution is a conversion to reverse total shoulder arthroplasty. The survivorship of the prosthesis is up to 12 years, which is acceptable by patients. Long term result are still not clear. Surgeons performing SA opt for deltopectoral approach which provides good exposure of the joint also for revisions. The aim: To summarize knowledge about SA based on current literature.

The Mean

Successful total shoulder arthroplasty is, in part, dependent on anatomic reconstruction of the glenohumeral joint. The purpose of this study was to evaluate the post-operative anatomy of total shoulder arthroplasty with an anatomic implant design in patients with primary glenohumeral osteoarthritis and compare it to published normative anatomic measurements. Fifty-one patients (56 shoulders) with primary glenohumeral osteoarthritis were treated with a press-fit humeral component as part of a total shoulder arthroplasty (Aequalis, Tornier, Edina, Minnesota). Analysis of postoperative true anterior posterior radiographs was performed with use of a custom software algorithm. The mean humeral inclination (head-shaft angle), mean humeral implant anatomical humeral axis, mean greater tuberosity height, and mean humeral head center offset (medial offset) were 135.4±5.1°, 1.73±1.7°, 6.9±2.4 mm, and 3.8±1.8 mm, respectively. All parameters were within the ranges reported in the literature for normal shoulders except the mean humeral head center offset, which was less than reported in the literature. Anatomic parameters of a total shoulder arthroplasty can be achieved with an anatomically designed, modular adaptable press-fit design. Reduced medial humeral head center offset was likely dependent upon implant specific design parameters.

Glenohumeral Osteoarthritis

Background: Few long-term outcome studies exist evaluating glenohumeral osteoarthritis (GHOA) treatment with arthroscopic management. Purpose: To determine outcomes, risk factors for failure, and survivorship for the comprehensive arthroscopic management (CAM) procedure for the treatment of GHOA at minimum 10-year follow-up. Study Design: Case series; Level of evidence, 3. Methods: The CAM procedure was performed on a consecutive series of patients with advanced GHOA who opted for joint preservation surgery and otherwise met criteria for total shoulder arthroplasty. At minimum 10-year follow-up, postoperative outcome measures included change in the American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, 12-Item Short Form Health Survey (SF-12) Physical Component Summary, and visual analog scale for pain, along with the QuickDASH (shortened version of Disabilities of the Arm, Shoulder and Hand) and satisfaction score. Kaplan-Meier survivorship analysis was performed, with failure defined as progression to arthroplasty. Results: In total, 38 CAM procedures were performed with 10-year minimum follow-up (range, 10-14 years) with a mean patient age of 53 years (range, 27-68 years) at the time of surgery. Survivorship was 75.3% at 5 years and 63.2% at minimum 10 years. Those who progressed to arthroplasty did so at a mean 4.7 years (range, 0.8-9.6 years). For those who did not undergo arthroplasty, American Shoulder and Elbow Surgeons scores significantly improved postoperatively at 5 years (63.3 to 89.6; P < .001) and 10 years (63.3 to 80.6; P = .007). CAM failure was associated with severe preoperative humeral head incongruity in 93.8% of failures as compared with 50.0% of patients who did not go on to arthroplasty ( P = .008). Median satisfaction was 7.5 out of 10. Conclusion: Significant improvements in patient-reported outcomes were sustained at minimum 10-year follow-up in young patients with GHOA who underwent a CAM procedure. The survivorship rate at minimum 10-year follow-up was 63.2%. Humeral head flattening and severe joint incongruity were risk factors for CAM failure. The CAM procedure is an effective joint-preserving treatment for GHOA in appropriately selected patients, with sustained positive outcomes at 10 years.

Congenital shoulder luxation in the dog is commonly associated with deformity of the humeral head and glenoid, making reduction and stabilization difficult. Early diagnosis of congenital luxation of the shoulder in a Papillon made it possible to successfully reduce and stabilize the luxation using a closed pinning technique. One year later the joint was functionally and radiographically normal.
