INTRODUCTION Women with extremely large breasts have many complaints. Reduction mammaplasty improves shape and relieves physical symptoms and alleviates psychological complaints. Mammaplasty is a an evolving technique; no single method is ideal or suitable for all breasts. Many techniques are advocated for reduction mammaplasty, including the superior, vertical, horizontal, lateral and inferior...

Surgical management of severe rigid dystrophic neurofibromatosis (NF) scoliosis is technically demanding and produces varying results. In the current study, we reviewed 9 patients who were treated with combined anterior and posterior fusion using different types of instrumentation (i.e., pedicle screw, hybrid, and all-hook constructs) at our institute.Between September 2001 and July 2010 at our...

OBJECT The C-2 pedicle plays an important role regarding screw purchase for spinal fixation. The aim of this study was to measure the C-2 pedicle-related linear and angular parameters. METHODS Seven parameters in 160 C-2 pedicles (80 dry vertebrae) were measured using a Vernier caliper (accurate to 0.1 mm) and goniometer. The Student t-test was used to determine statistical significance. The ...

BACKGROUND The foremost concern of a surgeon during pedicle screw fixation is safety. Assistive modalities, especially intraoperative electromyographic monitoring (EMG) can function as an essential tool to recognize screw malposition that compromise neural integrity, so that the screws can be repositioned immediately rather than later. We intend to study the efficacy of intraoperative EMG monit...

The paramedian forehead flap has become the standard of care for major nasal reconstruction. The classic procedure involves a second-stage operation to divide and inset the external pedicle. We present our experience in a clinical series using single-stage forehead flap reconstruction. Our indications include elderly patients, pediatric patients treated during mission trips, and any patient in ...

BACKGROUND Early success of microvascular free tissue transfer is dependent upon the patency of the primary vascular pedicle. In time, neovascularization from the recipient bed and surrounding wound margins into the graft may be sufficient to maintain flap viability. The time necessary for successful neovascularization to occur is unclear. Most believe that prior radiation therapy will delay th...

OBJECTIVE To evaluate the influence of pilot hole tapping on pullout resistance and insertion torque of pedicle screws with a conical core. METHODS Mechanical tests using a universal testing machine were performed on pedicle screws with a conical core that were inserted into pedicles in the fifth lumbar vertebra of calves. The insertion torque was measured using a torque meter with a capacity...

STUDY DESIGN Biomechanical, cadaveric study. OBJECTIVE To compare the fixation strength of a novel S1 pedicle screw insertion technique in a revision setting to a standard S1 pedicle screw and an L5 pedicle screw. SUMMARY OF BACKGROUND DATA Fusions to the sacrum remain a difficult clinical challenge. Very few salvage techniques exist when a nonunion occurs. METHODS The biomechanical integ...

and accessory rods at PSO level. Testing evaluated (1) accessory Study Design. In vitro cadaveric biomechanical study. Objective. To assess effects of 4-rod reconstruction, rod material, and anterior column support on motion and surface rod strain in a pedicle subtraction osteotomy model. Summary of Background Data. Pedicle subtraction osteotomy (PSO) can correct significant sagittal deformity ...

IMPORTANCE The paramedian forehead flap is used to reconstruct medium to large nasal defects. The staged nature, with its vascular pedicle bridging the medial eyebrow to the nose, results in significant facial deformity. Earlier division lessens this morbidity. OBJECTIVES To quantify flap neovascularization 2 weeks after the initial flap transfer and to describe an algorithm for earlier divis...
