“…The diagnosis in the remaining 103 (2.7%) of the arthroplasties was classified as ''miscellaneous,'' including fracture sequelae 32 , ankylosing spondylitis 32 , post-arthroscopic chondrolysis 33 , post-arthroscopic arthritis 21 , and other etiologies 8 Only two studies had a level of evidence of I and one had a level of II. Two had a level of evidence of III, and the remainder had a level of IV.…”

This is the first systematic review of the published evidence on glenoid component failure. Although the authors of individual articles proposed various risk factors for glenoid component failure, many of these relationships were not significant in the present study. A consistent methodological approach to future investigations is likely to improve the quality of the evidence on which patients, techniques, and prostheses are selected for total shoulder arthroplasty.

“…In Groh’s study, 83 patients were treated for primary shoulder osteoarthritis with joint replacement, using uncemented fluted pegged glenoid component [10]. At a minimum of 2 years’ follow-up, all glenoid components were assessed as having grade 0 radiolucency, and evidence of finger-like projections of bone between the flanges of the implant was found in 24 cases.…”

BackgroundGlenoid component failure is the most common complication of total shoulder arthroplasty. It can be correlated with failure of the component itself to resist wear and deformation, failure of fixation or failure of the glenoid bone. Anchor Peg Glenoid component (Depuy®) seems to have a higher bone fixation in biomechanical canine model: it is a all-polyethylene, concave component with one circumferentially fluted, central, interference-fit peg and three small cemented peripheral pegs.Materials and methodsWe realized a prospective study of Anchor Peg total shoulder arthroplasty, included 27 patients suffering from primary arthrosis or arthritis, without rotator cuff tear. A clinical and radiographic evaluation was performed at 3 months, 1 and 2 years; a CT scan was made in postoperative and analyzed central peg’s bone integration 1 year later.ResultsImprovement of postoperative Constant score and radiographic good results were correlated with satisfactory subjective results reported by patients. We observed radiolucent lines under glenoid component in 3 cases. Twenty-six CT scans were available at 1 year: it showed complete bone integration around the central peg in 21 cases and partial peripheral bone integration in four cases. Only one patient had any tissue integration around the peg, probably because of his implantation near cortical bone of scapular spine.Discussion/conclusionLong-term result of arthroplasty is correlated with glenoid durable fixation to underlying bone: this study shows higher fixation of glenoid component with bone integration of central peg. However, these results will have to be confirmed in a later revision.

“…4,23,25,36 Both with and without cement, different factors such as eccentric loading, poor bone quality, and high activity levels have been described as feasible reasons for loosening. 10,11,29 Metal-backed cementless bone-ingrowth glenoid components showed divergent results in the short term 4,12,16 and a high failure rate in the long term. 39 Good results have been found with cemented keeled and pegged all-poly implants.…”
