Results: The review of the literature yielded 15 studies on the effect of treatment options for osteoporosis on lumbar fusion rates. One study demonstrated an association between low bone mass as measured by Hounsfield Units and lower fusion rates. Six studies evaluated perioperative medical treatment of osteoporosis and showed higher fusion rates in patients treated with alendronate and teripa...

BACKGROUND Understanding of the pedicle anatomy is necessary for pedicle screw placement; however, there have been few Thai studies reporting on thoracic pedicle morphometry. OBJECTIVE To determine important anatomical measurements for thoracic pedicle screw fixation. MATERIAL AND METHOD T1-T12 vertebral pedicles were evaluated in 27 cadavers. The diameter angle, length and entry point of t...

BACKGROUND Although many techniques of reduction mammaplasty are currently in use, a prospective study quantitating the sensation of the nipple-areolar complex (NAC) after the performance of specific techniques has not been performed. OBJECTIVE The purpose of this study was to quantitate the postoperative sensation of the NAC after reduction mammaplasty and to compare the results on the basis...

Minimally invasive techniques in spinal surgery are increasing in popularity due to numerous potential advantages, including reduced length of stay, blood loss and requirements for post-operative analgesia as well as earlier return to work. This review discusses guidelines for safe implantation of percutaneous pedicle screws using an image intensifier technique. As indications for percutaneous ...

Descending branch of the lateral circumflex femoral artery (LCFA) is commonly used pedicle for ante- rolateral thigh (ALT) flap. Oblique branch of LCFA is an alternative pedicle that can be used in micro- vascular surgery. According to review of literature and to the best of our knowledge we could not find the use of oblique branch of LCFA as a pedicle of the ALT flap in regional soft tissue re...

OBJECTIVE To determine the entry for the dorsal pedicular screw in relation to the notch present at the junction of base of the lateral margin of superior articular process with superior border of transverse process in dorsal spine. The advantage of this technique is a constant and easily identifiable entry point which does not involve partial resection of the inferior facet, thus maintaining s...

Introduction Unilateral pedicle screw fixation and transforaminal cage for interbody fusion are well-established form of treatment for lumbar spondylolisthesis. It is cost effective and has shown to have a comparable outcome to bilateral pedicle screw fixation. We present a case of unilateral pedicle screw fixation and transforaminal cage for interbody fusion in a patient of Grade 1 Degenerativ...

STUDY DESIGN A retrospective cross-sectional study. PURPOSE The purpose of this study is to evaluate the accuracy and safety of free-hand pedicle screw insertion performed by a young surgeon. OVERVIEW OF LITERATURE Few articles exist regarding the safety of the free-hand technique without inspection by an experienced spine surgeon. METHODS The index surgeon has performed spinal surgery fo...

Pedicle screws are widely used for instrumentation of the thoracolumbar spine. The anatomic studies performed in the last two decades, detailing the complex morphometry and three-dimensional anatomy of the thoracolumbar pedicles, have enabled the emergence of the so-called "free-hand" technique of pedicle screw placement based exclusively on anatomical parameters. However, in the thoracic spine...

Free fibula flap is the most common free tissue transfer for maxillary and mandibular reconstructions. The distal part of the harvested bone is transferred, while the proximal part is removed by sub-periosteum dissection. The vascularized periosteum attached to the vascular pedicle has osteogenic potential. 61 patients reconstructed with free fibula flaps were divided in 2 groups: 41 flaps perf...
