Long-term survival of the glenoid components in total shoulder replacement for arthritis.

Purpose: Aseptic glenoid component loosening remains a common problem in total shoulder arthroplasty (TSA). This study presents long-term prospective follow-up after implantation of a glenoid component using the "cancellous compaction technique" and its effect on clinical outcome and presence and progression of radiolucent lines (RLLs).

Method: Thirty-nine TSAs were performed for primary osteoarthritis by one surgeon using the same technique.

Risk factors for dislocation arthropathy after Latarjet procedure: a long-term study.

Purpose: The purpose of this study was to analyse the long-term incidence of dislocation arthropathy after a modified Latarjet procedure for glenohumeral instability.

Methods: Long-term follow-up information was obtained from a consecutive series of patients who had undergone a modified Latarjet procedure by one surgeon between 1986 and 1999. Multivariable regression analysis was performed to examine the relation between the development of a dislocation arthropathy and patients and surgery-related factors.

Patterns of loosening of polyethylene keeled glenoid components after shoulder arthroplasty for primary osteoarthritis: results of a multicenter study with more than five years of follow-up.

Background: The aim of this study was to radiographically analyze the long-term glenoid migration patterns following total shoulder arthroplasty to better understand the factors responsible for loosening.

Methods: Complete radiographic follow-up of more than five years was available for 518 total shoulder arthroplasties performed for primary glenohumeral osteoarthritis with use of an anatomically designed prosthesis with a cemented, all-polyethylene, keeled glenoid component. Radiographs were assessed for humeral head subluxation, periprosthetic radiolucent lines, and shifting of the position of the glenoid component.

Results of a convex-back cemented keeled glenoid component in primary osteoarthritis: multicenter study with a follow-up greater than 5 years.

Purpose: We assessed the clinical and radiologic results of a cemented all-polyethylene convex-back keeled glenoid component used with a third-generation prosthesis.

Methods: Between 1996 and 2003, in 4 European centers, 333 shoulder arthroplasties were performed for primary osteoarthritis by use of a cemented all-polyethylene convex-back keeled glenoid component. Kaplan-Meier survivorship analysis was performed, and clinical outcome was assessed with the Constant score, range of motion, and subjective evaluation.
