2010 Radiofrequency energy on cortical bone and soft tissue CORR Open Access

Description: Radiofrequency-generating energy devices have been used clinically in musculoskeletal procedures to provide hemostasis and capsular shrinkage (thermal capsulorrhaphy). However, the dose-effects are not well known.
Questions/Purposes We therefore determined dosage effects of radiofrequency energy on bone, skin incisions, and joint capsule in sheep.
Conclusions Hemostasis can be achieved with radiofrequency energy at 190f in skin and bone. Bone necrosis was not detected at up to 570f. Using fluence greater than 190f in skin achieved dose-dependent necrosis and incisional contraction.
Clinical Relevance Radiofrequency energy can be used on bone and skin for hemostasis, but potential incisional complications, such as necrosis and an atypical firm and desiccated surface, should be expected.
