SURFACE ARTHROPLASTY FOR TREATING PRIMARY AND/OR SECONDARY SHOULDER OSTEOARTHROSIS BY MEANS OF THE HEMICAP-ARTHROSURFACE® SYSTEM

ABSTRACTObjective: To present the surgical technique for the He-miCAP-Arthrosurface® system and evaluate our results from this technique for treating primary and/or secondary shoulder osteoarthrosis. Method: Between June 2007 and June 2009, 10 shoulders of 10 patients (nine with primary osteoarthrosis and one with avascular necrosis of the humeral head) underwent surface arthroplasty using the HemiCAP-Arthrosurface® system to correct the problem. The follow-up time ranged from six to 29 months (mean of 17 months). The patients’ ages ranged from 62 to 73 years (mean of 67.5 years). Six patients were female and four patients were male. The patients were followed up weekly for the first month after the surgical procedure and every three months thereafter. The clinic evaluation was done using the criteria of the University of California at Los Angeles (UCLA) and a visual analogue pain scale. Results: All the patients said that they were satisfied with the results from the surgical treatment, with a mean UCLA score of 30 points and a mean analogue pain score of two points. Conclusion: The HemiCAP-Arthrosurface® system for shoulder surgery for a specific group of patients is a technique that preserves the bone stock with good functional and antalgic results
