AIMS: For preoperative planning and a better prediction of postoperative rehabilitation there is the need for a reliable and easily adjustable ultrasound imaging of the anteroinferior capsulolabroglenoidal complex. This is especially important for patients with recurrent anterior luxation, loose connective tissue and primar luxation between the age of 30 to 40. The purpose of this study was to evaluate a score with a reliable prediction of PERTHES-BANKART lesion by dynamic ultrasound examination of the shoulder with side to side comparison.
MATERAL: We could include 54 patients with a ventral glenohumeral luxation in this prospective study. The preoperative dynamic ultrasound examination was correlated with intraoperative arthroscopic findings. We show the used ten sonomorphological dynamic parameters which have influence on the result of a new score in short videoclips.
RESULTS: We present a score which allows a reliable detection of a PERTHES-BANKART lesion in the anteroinferior (2 to 5 o’clock) region. For the detection of this lesion this “AID” (Anteroinferior Defekt Score) has a sensitivity of 97.9%, a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 87.5%.
CONCLUSION: These results demonstrate that ultrasound and especially the new AID score is useful in detection of the PERTHES-BANKART lesion.
