A New Supermicrosurgery Training Model of Saphenous Artery and Great Saphenous Vein Anastomosis for Development of Advanced Microsurgical Skills.
Background This study aimed to confirm the feasibility and reliability of saphenous artery (SA) and great saphenous vein (GSV) anastomosis as a new supermicrosurgery training model and to compare the one-way-up anastomosis with the currently used end-to-end anastomosis technique. Methods Twenty supermicrosurgical anastomoses were performed in 10 Sprague Dawley rats. The external diameters of SA and GSV were measured using Leica LAS EZ software. ⋯ Seven-day anastomosis patency rates for arteries and veins were 80 and 100% for the end-to-end technique and 100 and 80% for the one-way-up technique, respectively. Conclusions We confirmed that saphenous pedicle is suitable for creating a supermicrosurgery training model for practicing the ultrafine motor skills. To the best of our knowledge, this is the first report on supermicrosurgery of SA and GSV in the rat model.

Comparative StudyA Comparison of Vascularized Free Fibular Flaps and Nonvascularized Fibular Grafts for Reconstruction of Long Bone Defects after Tumor Resection.
Background The use of the fibula autograft has been a reliable method in the reconstruction of long bone defects after tumor resection. The objective of this study was to report the outcomes fibular grafting in terms of graft union, functional score, complications, and oncologic outcome. Methods A retrospective review of patients with fibular grafting after tumor resection was done from January 1, 1993 to December 31, 2013. ⋯ On final follow-up, 45 of 52 patients were alive, six patients had died of disease and one died of other causes. Conclusion A higher union rate was achieved using vascularized free fibular flaps compared with nonvascularized fibular grafts for long bone reconstruction after tumor resection. There was no difference in terms of MSTS score between the two types of grafts.

Background While other surgical specialties have embraced virtual reality simulation for training and recertification, microsurgery has lagged. This study aims to assess the opinions of microsurgeons on the role of simulation in microsurgery assessment and training. Methods We surveyed faculty members of the American Society of Reconstructive Microsurgery to ascertain opinions on their use of simulation in training and opinions about the utility of simulation for skills acquisition, teaching, and skills assessment. ⋯ Ninety-four percent had no experience with simulator-based assessment. Conclusion Simulation has been shown to improve skills acquisition in microsurgery, but our survey suggests that unfamiliarity may foster bias against the technology. Failure to incorporate simulation may adversely affect training and may put surgeons at a disadvantage should these technologies be adopted for recertification by regulatory agencies.

Phrenic Nerve Transfer for Reconstruction of Elbow Extension in Severe Brachial Plexus Injuries.
Background Restoring elbow extension is an important objective to pursue when repairing the brachial plexus in patients with a flail arm. Based upon the good results obtained using the phrenic nerve to restore elbow flexion and shoulder stability, we hypothesized that this nerve could also be employed to reconstruct elbow extension in patients with severe brachial plexus injuries. Methods A retrospective study of 10 patients in which the phrenic nerve targeted the radial nerve (7 patients) or the branch to the long head of the triceps (3 patients) as a surgical strategy for reconstruction of the brachial plexus. ⋯ At final follow-up, elbow extension graded as M4 was measured in three patients, Medical Research Council MRC M3 in five patients, and M2 in one patient, while one patient experienced no measurable recovery (M0). No patient complained or demonstrated any signs of respiratory insufficiency postoperatively. Conclusions The phrenic nerve is a reliable donor for reanimation of elbow extension in such cases, and the branch to the long head of the triceps should be considered as a better target for the nerve transfer.
