BACKGROUND Current teaching suggests increased perfusion in free transverse rectus abdominis myocutaneous (TRAM) flaps over pedicled TRAM flaps, broadening indications for its use in high risk patients. This study compared perfusion analysis of free muscle-sparing versus pedicle TRAM flaps in vivo in the peri-operative and late post-operative periods. METHODS The SPY-Elite system using indocy...

Right hepatectomy for hepatocellular carcinoma is the most common major operation in liver surgery; therefore, liver surgeons should know the fundamental surgical concept and techniques of the Glissonean pedicle approach. A J-shaped or reversed T laparotomy is performed in the right subcostal area. The Glissonean pedicle approach is performed at the hepatic hilus. In this approach, the right an...

OBJECTIVE To compare the von Mises stresses of the internal fixation devices among different short segment pedicle screw fixation techniques to treat thoracic 12 vertebral fractures, especially the mono-segment pedicle screw fixation and intermediate unilateral pedicle screw fixation techniques. METHODS Finite element methods were utilised to investigate the biomechanical comparison of the fo...

OBJECTIVE A variety of different pedicle screws entry point techniques are used for the lumbar pedicle screws placement. This study reported Kim's entry point of lumbar pedicle screws with free hand technique and the accuracy of this technique. METHODS We retrospectively reviewed the 584 cases with free hand placed lumbar pedicle screw placement. The diagnosis included 491 cases with degenera...

Cervical pedicle screw has been shown to provide stronger fixation than other methods. Due to these virtue of biomechanical characteristic, pedicle screw fixation can be used in a wide range of cervical spinal disorders, and excellent clinical results have been reported. However, this procedure is technically demanding because of the great variation in pedicle dimension and angulations between ...

Background: Lumbar skin flaps based on cutaneous perforators arising from the lumbar artery have been described for coverage of lumbosacral defects and as free flaps for autologous breast reconstruction. Thus, the purpose of this study is to clarify anatomical aspects of the lumbar artery perforator flaps pertaining improvement in utility and design of this flap. Methods: Five fresh human bodie...

Minimally invasive thyroid surgery, using various techniques including endoscopic and video-assisted have been reported. Thyroid surgery using a mini-incision over the upper pole of the thyroid, as a new technique is presented here. Methods: The study group comprised of 52 patients undergoing minimally invasive thyroid surgery (MITS) by open method during the period May 2005-May 2013. Data rega...
