BACKGROUND: Pedicle screw fixation in high grade lumbar listhetic vertebral body has been nightmare for Orthopaedic and spine surgeons. This is because of abnormally positioned listhetic pedicles and non-visualization of pedicle in conventional image intensifier (C-Arm). This results into increased surgical time, more blood loss, radiation exposure and more chances of infection. To overcome this problem, we have devised a new Technique of putting of pedicle screw fixation in listhetic vertebrae...

PURPOSE: Accurate and safe posterior thoracic pedicle insertion (PTPI) remains a challenge. Patient-specific drill templates (PDTs) created by rapid prototyping (RP) can assist in posterior thoracic pedicle insertion, but pose biocompatibility risks. The aims of this study were to develop alternative PDTs with computer numerical control (CNC) and assess their feasibility and accuracy in assisting PTPI. METHODS: Preoperative CT images of 31 cadaveric thoracic vertebras were obtained and then the optimal pedicle screw trajectories were planned...

INTRODUCTION: Free muscle flaps are being used more commonly for complex lower limb reconstruction. Up to 33% of flaps used to reconstruct lower limb trauma will require an orthopaedic procedure after reconstruction. To date there have been only case reports detailing the variable survival of muscle flaps after actual or simulated pedicle injury and the process and timeframe of neovascularisation remains undefined. We aim to show that perfusion of a muscle flap is possible after injury to its anatomical vascular pedicle...

Post-radiotherapy carotid blowout syndrome (CBS) of the skull base is a rare but often catastrophic complication of head and neck malignancies. The existing literature on the treatment of this condition with flow-diverting devices (FDD) is extremely limited and disappointing. We present a case of impending CBS in a patient previously irradiated for nasopharyngeal cancer that was successfully treated with use of multiple FDDs, adjunctive endonasal packing and delayed reinforcement with pedicled naso-septal flap, yielding an excellent outcome at 14-months follow-up...

Moyamoya is an idiopathic and progressive disease that leads to occlusion of intracranial arteries. When other methods of revascularization fail, omentum can be used as an indirect bypass to improve cerebral perfusion. Laparoscopic mobilization of a pedicled omental flap with subcutaneous tunneling to the brain has been described in small case series in children. We report our techniques and outcomes in 2 adults with Moyamoya to undergo such a procedure. An omental flap based on the right gastroepiploic artery was created and intraoperative fluorescence imaging using indocyanine green was used to assess the viability of the flap and to guide lengthening of the pedicle...

The facial-cervical scars bring the suffering to the patients both physically and mentally. Choosing a proper donor soft tissue is always one of the critical issues, especially to Asian patients. Among the common used donor sites, the deltopectoral site was conceived as the most suitable donor tissue for the reconstruction in face and neck for its adjacent site and match in color and texture. There were 220 patients with facial-cervical scars reconstructed by the pedicled expanded deltopectoral flap between 2007 through 2015 in the authors' hospital...

Gout is an inflammatory arthritis characterized by deposition of monosodium urate crystals in joints. Though gout frequently involves the big toe or other extremities, it rarely occurs in the spinal canal. A 35-year-old man presented with left L5 radiculopathy. He had leg pain for 8 months and received several epidural steroid injections. Magnetic resonance imaging revealed a 1.7×1.1-cm ovoid contrast-enhancing mass, causing pressure erosion of the left L5 pedicle. Microscopic laminotomy was performed at the left L5 lamina...
