Is the postoperative shoulder function affected by angle of implants, horizontal and vertical instability after ACJ reconstruction with Double TightRope - 26/11/15
Résumé |
Objective |
The objective of this study was to examine the influence of the implant positioning and the horizontal and vertical instability of the ACJ after Double TightRope reconstruction on the shoulder function.
Materials and methods |
Thirty-one patients with ACJ dislocation Rockwood V, reconstruction with Double TightRope without (group 1, 20 pat.) and with additional augmentation of the ACJ (group 2, 11 pat.). FU: 46.2months. ACJIS, Taft-score, SSV, Alexander-view, shoulder panorama view and a axial stress-view.
Results |
Group 1: ACJIS: 75.1P; Taft-score: 9.8P; SSV: 90.4% Group 2: ACJIS: 72P; Taft-score: 10.1P; SSV: 90%. Mean angle implants: 5.9°. Shoulder panorama view: 90.3% vertical instability ACJ; axial stress-view: 80.6% horizontal instability; Alexander-view: 61.3% instability. Significant reduction CC-distance of 6.3mm (P<0.001), significant increased comparing to the contralateral side (P=0.002). No significant postoperative difference in ROM (P>0.05), on instability by ACJ-augmentation (P<0.05), on the radiological stability by position of the implants and by the radiological instability in the Alexander-view (P>0.05). Satisfactory comparability of the scores to evaluate the ACJ (P<0.001).
Conclusion |
Using the Double TightRope procedure, no possibility to achieve anatomical reconstruction in every plane. The postoperative shoulder function and stability of the ACJ is not influenced by the additional ACJ-augmentation and the angle of the implants.
