ShoulderLong-term follow-up of total shoulder replacement surgery with inset glenoid implants for arthritis with deficient bone
Section snippets
Materials and methods
We retrospectively studied 24 patients on whom the senior author performed total shoulder replacement with inset glenoid implants for severely deficient bone between 2005 and 2009. Twenty-one of these patients were still alive and available for follow-up. Minimum follow-up was 6 years. Fourteen patients returned to clinic for full clinical follow-up including final XRs, and 7 patients could only be reached by phone for final outcome scores. Two patients died during the study period, and 1
Results
In this cohort of 24 consecutive surgeries performed with inset glenoid implants for deficient bone between 2005 and 2009, 21 patients were located for the final follow-up. Mean follow-up on these 21 patients was 104 months (range, 76-142 months). All patients were right hand dominant. The affected shoulders were the right dominant shoulder in 6 cases and left in 15 (Table I). Patient age ranged from 49 to 83 years with a mean age of 68 years. The average retroversion was 18° and the average
Discussion
This long-term study is a retrospective review of 21 of 24 consecutive surgeries with inset glenoid implants performed in patients with shoulder arthritis and severely deficient glenoid bone between 2005 and 2009. Our previous short-term study on a smaller cohort of patients with a minimum 3-year follow-up showed excellent results on these difficult patients,10 but there are no long-term results available in the literature using this new inset technique. The goal of this study was to evaluate
Conclusion
This inset glenoid fixation technique offers an innovative approach to a difficult clinical conundrum of shoulder arthritis with deficient glenoid bone. In this series, there were no complications, no cases of glenoid implant loosening, and no revision surgeries performed at a mean 8.7-year follow-up. This technique is also safe, because there is only minimal penetration of the glenoid surface bone. Finally, the technique is simple and easily reproducible. It is a reasonable alternative to
