Although bipolar cautery was designed to minimize trauma to the central nervous system, little is known about the effects of bipolar cautery on peripheral nerve tissue. This experiment was designed to study the effect of direct bipolar cautery on a peripheral nerve and the muscles innervated by that nerve. Lewis rats (n = 200) were assigned to five different groups: control, sham, and three cautery groups (duration of either 0.5, 1.0, or 1.5 seconds). The hind limb tibial nerves were isolated in the sham group and isolated and cauterized in the cautery groups. Assessments performed at 2 hours, 2 weeks, 4 weeks, and 8 weeks postoperatively included isometric contractile function studies of both a fast- and a slow-twitch muscle, muscle weights, and nerve histology/morphometry. Significant muscle weight loss and reduced muscle function were found in the cautery groups at 2, 4, and 8 weeks (p < 0.05). Histologically, the nerves of the cautery groups showed nerve damage consistent with Sunderland's type 4 nerve injury when examined at 2 weeks and showed nerve regeneration at 4 and 8 weeks. Both the fast-twitch muscle and the shorter duration cautery were associated with faster recovery relative to the slow-twitch muscles and longer duration cautery, respectively. Bipolar cautery, as administered to rat tibial nerves in this experiment, is associated with a significant injury to the nerve and loss of function of the muscles innervated by the nerve.
