OBJECTIVE: To describe the technique of US-guided shoulder arthrography using a pediatric needle (modified Valls- Melloni technique) and to assess its efficacy. MATERIAL AND METHODS: Descriptive study of articular puncture for 48 magnetic resonance imaging arthrographs of the shoulder in 48 consecutive patients. The puncture was performed by a radiologist without prior experience in the technique. We used an anterior approach to the shoulder, guiding the puncture using US according to the Valls-Melloni technique; however, we used a pediatric spinal needle (Yale spinal; 22G: 0.7 x 40 mm). The efficacy of the technique was evaluated using the following variables: time employed, number of attempts, extravasation of contrast outside the joint, pain reported by the patient (on a scale from 0 to 10), and immediate or late complications of the technique. RESULTS: The time required for the procedure was 15.2+/-2.6 min (mean+/-standard deviation). A single puncture sufficed in 45 patients (94%); two attempts were necessary in two patients (4%) and three in one patient (2%). Contrast extravasation outside the joint occurred only in two patients (4%). The mean pain reported was 3.6 points (confidence interval: 3.1-4). Three patients (6%) had a vasovagal reaction. No late complications were observed. CONCLUSION: US-guided shoulder arthrography using a pediatric spinal needle is fast, simple, and safe; it can be performed by any radiologist, even without prior experience in the technique.
