To determine the complication rates after total elbow arthroplasty (TEA) in a large and diverse patient population.
We identified patients undergoing TEA as inpatients in the years 1995 to 2005 using California's Discharge Database. Short-term outcomes of interest included rates of infection or wound complications, revision, reoperation, and pulmonary embolism that were diagnosed during an inpatient hospital admission and mortality within 90 days of index surgery. Longer-term outcomes analyzed included rates of revision, amputation, and conversion to fusion. We used regression models to estimate the role of patient and provider characteristics in predicting the rates of adverse outcomes.
We identified 1,625 patients undergoing TEA. Early complications, defined as those requiring inpatient re-admission within the first 90 days after index surgery, were identified in 170 patients, and 132 patients required reoperation. Eighty one patients required revision in 90 days, and 48 underwent revision within one year. Early infections and wound complications requiring readmission occurred in 88 patients. In the 90 days after surgery, 4 patients had a pulmonary embolism and 10 patients died. One-hundred and twenty-one patients required revision, amputation, or fusion during the observation period, with a mean follow-up of 4 years. Hospital volume was not associated with increased risk of adverse outcomes.
Therapeutic IV.
We analyzed a large and diverse patient population undergoing TEA. The overall rate of short-term complications requiring inpatient treatment was high, at over 10% (170 patients), with almost 8% (132 patients) requiring reoperation within the first 90 days. Although population-based studies have shortcomings, they can add to the body of knowledge of less frequent procedures such as TEA.
