Arthroscopic treatment of recurrent anterior shoulder dislocation. Analysis of technical changes on caspari procedure

Abstract

differences in the outcome, but we believe that also modifications in the technique represent important variables. Purpose of this study was to compare result~ of Caspari technique with a personally modified one to evaluate the effectiveness of our technical changes, Arthroscopic treatment was performed on 71 patients with recurrent shoulder dislocations, Patient selection includes only patients with monoplanar anterior instability. Of the 71 operations, 29 were performed using original Caspari technique (follow-up 59 months) and 42 were performed after modifications made in the original technique (follow up 38 months), notably improved preparation of the capsular re-insertion zone, increase in the number of monofilament points and their anchorage directly to the bone, on the spine of the scapula. Comparison of the results obtained in these two differently treated groups was executed analyzing the number of dislocation episodes prior to the operation, as well as clinical, findings regarding, stability, movement, function and pain (Rowe scale score), contralateral shoulder laxity, resumption of sport activity and postoperative recurrence rate, Student test and correlation coefficient test were used for statistical analysis.
