Quantitative analysis of regenerated nerves between experimental groups showed that those repaired by direct contact of the stumps with fibrin glue showed significant increase in the myelin and fiber areas. The tubulization groups, repaired by suture or fibrin glue, provided similar results. G-ratio analysis revealed that the regenerating axons of all experimental groups presented values equivalent MK-8669 to control (crushing group). These results suggest that the use of fibrin glue in nerve repair by either direct coaptation or tubulization
is an alternative to conventional suture repair, particularly in case of small-size-nerve reconstruction. © 2013 Wiley Periodicals, Inc. Microsurgery 33:468–477, 2013. “
“Microvascular procedures not only demand precise movements but also usually
require a long operation time. Using a conventional surgical microscope, microvascular surgeons need to keep the neck in a fixed flexion posture, which can lead to physical fatigue. Thus, our aim was to develop a three-dimensional (3D) monitoring system to improve the microsurgery environment. It consists of four main parts: the surgical microscope, the charge-coupled devices, the 3D multiplexer, and the 3D monitor. Two patients with head and neck cancers who underwent tumor resections were reconstructed with free flap microsurgeries. Both artery anastomoses were completed successfully and the postoperative courses of the two patients were smooth. Vascular anastomosis can be performed successfully with the help of the new 3D display system. Although the artery anastomosis procedures took longer than under a surgical selleck inhibitor microscope, the 3D system offers another option to improve the working environment for surgeons. © 2012 Wiley Periodicals, Inc.

“The
goal for treatment of osteonecrosis of the femoral head (ONFH) is to relieve pain, preserve the contour of the femoral head, and delay the need for total hip arthroplasty. The free vascularized fibular grafting (FVFG) has been shown to support the subchondral architecture as well as restore local circulation for the necrotic femoral NADPH-cytochrome-c2 reductase head in treatment of ONFH. This report aimed to present the clinical results of the use of a modified surgical technique of FVFG for treatment of ONFH. Four hundred and seven patients with 578 hips of ONFH were included. The patients’ average age was 36.7 years old (ranging 19–55 years old). The disease was staged from II to V based on the Steinberg classification system. By the modified procedure, the vascularized fibular graft was harvested via a lateral incision with fibular osteotomy prior to the exposure of the vascular pedicle, and the removal of necrotic tissue and inset of graft were performed through an anterior approach. The operative time averaged 90 min for unilateral ONFH (ranging 75–110 min) and 190 min for simultaneous treatment of bilateral ONFH (ranging 160–230 min).
