摘要
To compare three approaches via the anterior and posterior glenohumeral joints, and the rotator interval in fluoroscopy-guided shoulder arthrography according to the experience of the practitioners. This prospective randomized study was originally designed to have 34 subjects for each approach, and finally evaluated 98 patients (mean age: 51.5 years; 55 men) from July to December 2014, who had shoulder arthrography via the anterior (n = 41) or posterior glenohumeral joint (n = 27) approaches, or via the rotator interval approach (n = 30) by residents (n=76) or fellows (n=22). The success rate, number of punctures, fluoroscopy time, radiation dose, and complications of the three methods were compared, and according to the practitioners. The success rate was 100% for the anterior glenohumeral joint approach (34 out of 34), 90.0% for the posterior glenohumeral joint approach (23 out of 30), and 88.2% for the rotator interval approach (30 out of 34; p = 0.013). There was no difference in the success rate according to the practitioners' experience. Fluoroscopy time was longest for the posterior glenohumeral joint approach (mean: 95.44 s) and shortest for the rotator interval approach (mean: 31.57 s, p = 0.006). Radiation dose was larger by 1st- or 2nd-year residents (p = 0.014), with no difference among the three approaches. Only one patient who underwent arthrography using the posterior glenohumeral joint approach complained about post-procedural pain. Fluoroscopy-guided shoulder arthrography via the posterior glenohumeral joint or rotator interval approach may be difficult for trainees, and the posterior glenohumeral joint approach may need a long fluoroscopy time.
