2009 Early To Medium Term Results of the Anatomical Total Shoulder Replacement

Description: We report the functional and radiographic outcomes of use of the modular Anatomical shoulder system (Zimmer) at our institution.Methods: A series of 33 shoulders (30 patients) where followed up for a mean of 37.4 months . Two patients died and three were lost to follow up. Pre-op diagnosis in the remainder was osteoarthritis (20), post-traumatic (6), and avascular necrosis (1). The mean age was 74 years.Results: Visual Analogue Pain (VAP) scores improved significantly (p<.05) from an average pre-op score of 8.8 to an average post-op score of 2.5. The mean post-op Disability of Arm, Shoulder and Hand (DASH) score was 38. The Modified Neer Rating for all was 11 excellent, 12 satisfactory, four unsatisfactory. Four cases showed signs of glenohumeral radiolucency but no evidence of progression. One periprosthetic fracture was managed successfully non-operatively. and one dislocation managed with closed reduction.Conclusion: The Anatomical total shoulder replacement provides satisfactory functional and radiographic outcomes and is readily achievable in this group of patients in the short to medium term follow up.
