Shoulder Replacement (Subscribe)  

A simple unconstrained shoulder prosthesis has been used in 22 patients (25 shoulders) with incapacitating pain and severely damaged joints who, because of age or generalised rheumatoid disease, have limited functional requirements. All reported good and lasting pain relief. Improvement in range of movement was modest, but there was marked...

Full Text of JBJS B 81: 3, 495 Replacement of the proximal humerus in 18 children aged between 6 & 12 after bone tumour resection. The prosthesis allowed lengthening which was performed on 11 patients (mean 3 cms)

We reviewed 80 shoulders (77 patients) at a mean follow-up of 44 months after insertion of a Grammont inverted shoulder prosthesis. Three implants had failed and had been revised. The mean Constant score had increased from 22.6 points pre-operatively to 65.6 points at review. In 96% of these shoulders there...

We studied the stability of cemented all-polyethylene keeled glenoid components by radiostereometric analysis (RSA) in 16 shoulders which had received a total shoulder replacement. There were 14 women (one bilateral) and one man with a mean age of 64 years. The diagnosis was osteoarthritis in eight and rheumatoid arthritis in...

Recognising that timely dissemination of information in the orthopaedic community was important and in the absence of any national guidelines for shoulder arthroplasty, the Scottish shoulder arthroplasty registry, a voluntary registry, was started in 1996. The goals of the registry were to assess contemporary practice, provide a benchmark against which...

CONCLUSION: The initial Nottingham shoulder prosthesis showed significantly higher survivorship than the BioModular uncemented prosthesis, but lower than expected. Subsequently re-designed Nottingham TSR system presented a high short term survivorship rate that encourages its ongoing use.
Improvements in survival of the uncemented Nottingham Total Shoulder prosthesis: a prospective comparative study. Rosenberg N,...

Objective: To evaluate functional outcome after hemiarthroplasty for displaced proximal humeral frac- tures and to review whether prosthesis type, intraoperative technique or previous ipsilateral shoulder surgery could affect the outcome.
Conclusion: We conclude that soft tissue status and operative technique play an im- portant role in late postoperative pain and range...

Implant failure is a serious complication in reverse shoulder arthroplasty. We determined the incidence of glenosphere disengagement in a cohort of 479 reverse shoulder prostheses
Disengagement of the glenosphere occurred in 16 of 479 shoulders (3.2%). In 13 patients, the disengagement was partial (clear step-off between the baseplate and the glenosphere)...

Medial wear on the polyethylene component after reverse shoulder arthroplasty (RSA) has been attributed to impingement of the humeral cup on the lateral border of the scapula. We present a case that illustrates that the presence of early heterotopic ossification may exacer- bate medial wear of the polyethylene component in...

Correct identification of the center point of the glenoid surface guides glenoid component placement. It is unknown whether the center point on the glenoid surface corresponds to the center of the glenoid vault at the medial extent of the glenoid prosthesis. We reviewed 20 consecutive computed tomography scans obtained preoperatively...

We report the functional and radiographic outcomes of use of the modular Anatomical shoulder system (Zimmer) at our institution.Methods: A series of 33 shoulders (30 patients) where followed up for a mean of 37.4 months . Two patients died and three were lost to follow up. Pre-op diagnosis in the...

The purpose of this study was to analyze pre-operative and intra-operative factors that affect the outcome of shoulder arthroplasty. We undertook a retrospective review of all shoulder arthroplasties performed at our institution between 1986 and 2003. Patients were contacted and outcomes were assessed using the Simple Shoulder Test and the...

PURPOSE. To report the clinical and radiographic results and complications of the Delta III reverse prosthesis. METHODS. 24 women and 2 men aged 62 to 84 (mean, 75) years underwent total shoulder replacement using the Delta III reverse prosthesis. Patient diagnoses were massive rotator cuff tear (n=20), disabling sequelae of...

Total shoulder arthroplasties (TSA) are being performed more commonly for treatment of arthritis, although fewer than either hip (THA) or knee (TKA) arthroplasties. Total shoulder arthroplasty also provides general health improvements that are comparable to THA. One study suggests TSAs are associated with lower morbidity and mortality than THAs and...

The impact of infraglenoidal scapular notching in reversed total shoulder arthroplasty (RTSA) is still controversially discussed. Our goal was to evaluate its potential influence on subjective shoulder stability and clinical outcome. We hypothesized that subjective instability and clinical outcome after implantation of RTSA correlates with objective scapular notching.
Conclusions We conclude that...
