The significance of preoperative shoulder arthrography in painful arc patients.
Preoperative shoulder arthrography was performed on 34 patients with painful arc syndromes. Rotator cuff rupture was diagnosed in 20 cases. Out of these the arthrography correctly showed rupture in 17 cases, while in one case rupture was not seen and two examinations were unsuccessful. Rotator cuff rupture was not found in 14 cases at operation. Of these, arthrography had been negative in eight cases and in six cases the rupture had merely been suspected. Sensitivity of shoulder arthrography in showing rotator cuff rupture was thus 85%, specificity 57% and accuracy 74%. The biceps tendon was intact in all cases with rotator cuff rupture. So-called "bicipital leakage" was seen in four cases, but its significance remains unclear.
