Anatomical study of the innervation of the posterior elbow joint capsule: implications for ultrasound-guided peripheral nerve block and radiofrequency ablation procedures.
Ultrasound-guided peripheral nerve block and radiofrequency ablation have been developed for pain management in various joints including the hip, knee and shoulder, but not the elbow. Precise three-dimensional (3D) localization of the articular branches and landmarks visible on ultrasound are needed. The objectives of this anatomical study were to determine the presence, course, frequency, landmarks and areas innervated by the articular branches supplying the posterior elbow joint. ⋯ The 3D data of the articular branches supplying the posterior elbow joint provide an anatomical basis for the development of peripheral nerve block and radiofrequency ablation protocols to treat elbow joint pain. Further anatomical and clinical studies are necessary to identify target sites and evaluate the proposed landmarks in vivo.

Comparative StudyCorrelation between epidural space depth measured with ultrasound and MRI compared to clinical loss of resistance when performing lumbar epidural steroid injection.
This prospective study assessed the accuracy of MRI and ultrasound (US) measurements as a preprocedural assessment tool for predicting clinical loss of resistance depth (CLORD) during fluoroscopy-guided lumbar epidural steroid injections (ESIs). ⋯ MRI measurements are preferable over US for preprocedural assessment of patients receiving lumbar ESIs for predicting CLORD.
