[Open versus arthroscopic shoulder stabilization. An analysis of the treatment costs].
In this study the total costs of clinical open and arthroscopic anterior shoulder stabilization were evaluated, analyzed and compared. From 1988 to 1998 147 patients underwent open (Bankart) or arthroscopic (ASK) anterior shoulder stabilization. We randomized two groups of 30 patients for each method (Bankart: 25 male, 5 female, 29 years of age; ASK: 25 male, 5 female, 26 years of age) and evaluated the costs of their clinical treatment. The total cost was significantly ( p<0.05, Mann-Whitney U-Test) higher for the open (5639 euro) than for the arthroscopic (4601 euro) therapy. There was a significant difference between the groups for the average cost of surgery (Bankart: 2741 euro; ASK: 2315 euro, p<0.05) and the average postoperative treatment cost (Bankart: 2202 euro; ASK: 1630 euro, p<0.05) whereas the average preoperative treatment cost was not significantly different (Bankart: 669 euro, ASK: 657 euro). The staff costs for the surgical procedure (Bankart: 1800 euro (32%), ASK: 1319 euro (29%)) and the postoperative staff costs of the nurses (Bankart: 1271 euro (23%), ASK: 997 euro (22%)) represented the greatest parts of the total costs. The average duration of the clinical treatment was 15.8 days for the open- and 12,4 days for the arthroscopic group.
