Total replacement of arthritic shoulder joints, although rare, carries no greater risk of complications than replacement of other major joints, a US study suggests.
Researchers looked at the results of 15, 414 hip surgeries, 34, 471 knee operations and 625 shoulder procedures.
Those who had shoulder surgery had 7.5% post-surgical complications compared with 15% for those patients who had their hips and knees replaced. The average time a patient remained in hospital after surgery was 2.4 days for shoulder patients, versus more than four days for both the hip and knee equivalents.
Lead author Edward McFarland, from Baltimore's Johns Hopkins Hospital, said: 'Comparatively, total shoulder surgery is just as safe and effective as other types of arthroplasties.'
