The training and careers of regional anesthesiology and acute pain medicine fellows, 2013.
Fellowships in regional anesthesiology and acute pain medicine (RAAPM) have grown exponentially during the past decade, both in terms of total programs and fellows trained. This survey-based study reports fellowship graduates' assessment of the strengths and weaknesses of their training and how the fellowship has affected their careers. ⋯ The results of this study should prove useful to fellowship directors as they refine the educational offerings of their programs.

Radiofrequency Ablation Near the Bone-Muscle Interface Alters Soft Tissue Lesion Dimensions.
Radiofrequency (RF) lesions are safe and effective in the treatment of spine pain; however, models developed to study factors affecting lesion dimensions have been performed in homogeneous media that may not accurately simulate human anatomy and electrophysiology. We present a novel ex vivo porcine model for performing RF lesion studies and report the influence of bone on projection of RF ablation lesions into soft tissue. ⋯ Bone adjacent to RF lesions alters the surrounding electrophysiological environment causing RF lesions to project further perpendicularly from the needle axis, vertically to bone, than previously expected. This phenomenon should be considered in the future modeling and clinical practice of RF.
