Results of Surgical Treatment of Denerative Arthropathy of the Rotator Cuff Using Hemiarthroplasty- Cta(®).

OBJECTIVE To assess results of CTA(®) partial shoulder arthroplasty for treatment of degenerative arthropathy of the rotator cuff. METHODS Between December 2006 and June 2009, 23 shoulders of 23 patients were submitted to CTA(®) type partial shoulder arthroplasty for treatment of arthropathy secondary to rotator cuff injury. Post-operative follow up time ranged from 6 to 35 months. Mean age was 74.1 years. Patients were predominantly female, representing 78.3% of cases. The right limb was affected in 18 patients. All patients had undergone at least 6 months of physiotherapy without improvement of the algetic picture, and being submitted to surgery by the same surgical team. None of the patients had history of surgery on the affected shoulder. The method elected for assessing patients during post-operative follow up was based on UCLA scoring criteria. RESULTS Improvement in pain was observed in all patients after arthroplasty. Mean UCLA pain score was 9.22 (ranging from 10 to 8). Mean function was 6 (10 to 2). Active frontal flexion was 2.39 (highest score 4 and lowest 0). Mean frontal flexion force was 4.09, maximum was 5 and minimum 3. Mean score on the UCLA was 26.52. 95% were satisfied with the surgery. CONCLUSION CTA(®) type partial shoulder arthroplasty produced satisfactory results in the treatment of degenerative arthropathy of the rotator cuff and had a low rate of complications.
