Radiographic comparison of finned, cementless central pegged glenoid component and conventional cemented pegged glenoid component in total shoulder arthroplasty: a prospective randomized study

Background: Depending upon the mechanism of dysfunction or injury a shoulder arthroplasty can either be a partial or total replacement. Shoulder arthroplasty surgery has shown remarkable progress during the last few decades. The objective was to study the effect of prosthesis positioning in reverse shoulder arthroplasty on radiological and clinical outcomes.Methods: This was a prospective comparative non-randomized study of 37 patients who underwent reverse shoulder arthroplasty (RSA) in Government District Head Quarters Hospital Nagapattinam with a follow-up ranging from March 2018 to January 2019 (11 months).Results: Grade 1 indicated a notch limited to the scapular pillar, grade 2 reached the inferior screw of the baseplate, grade 3 extended beyond the inferior screw and grade 4 reached the central peg of the baseplate. Glenoid loosening was defined as radiolucencies under the baseplate or around the peg or screws, screw breakage, or glenoid migration.Conclusions: Outcome measures were improved regardless of the LHO. At 3 months follow-up increased LHO harmed shoulder function and gave more shoulder pain at rest and exertion but did not affect the quality of life, health status, or ROM. At 12 months follow-up, LHO had no relation with the outcome measures. Further studies are warranted to investigate the influence of LHO on long-term prosthetic survival.

Component Loosening

Anatomic total shoulder arthroplasty (TSR) has been shown to generate good to excellent results for patients with osteoarthritis and a functioning rotator cuff. Many studies have reported that the glenoid component loosening and failure remain the most common long-term complication of total shoulder arthroplasty. The approach to glenoid component is critical because a surgeon should consider patient-specific anatomy, preserving bone stock and joint line restoration, for a good and durable shoulder function. Over the years, different glenoid design and materials have been tried in various configurations. These include cemented polyethylene, uncemented metal-backed and hybrid implants. Although advances in biomechanics, design and tribology have improved our understanding of the glenoid, the journey of the glenoid component in anatomic total shoulder arthroplasty has not yet reached its final destination. This article attempts to describe the evolution of the glenoid component in anatomic TSR and current practice.
