The effects of extraoral combined high-pull traction and cervical traction of known duration (mean, 122 days) and magnitude (2.5 to 3 pounds total per side) were studied by means of serial lateral cephalometric head films of thirty patients. The lateral cephalometric head films used were taken at three different times: before the extraoral force was applied, after the prescribed period of conti...

BACKGROUND Femoral fracture is a common battlefield injury with grave complications if not properly treated. Traction splinting has been proved to decrease morbidity and mortality in battlefield femur fractures. However, little standardization of equipment and training exists within the United States Armed Forces. Currently, four traction splints that have been awarded NATO Stock Numbers are in...

[1] The shear tractions that mantle flow exerts on the base of Earth’s lithosphere contribute to plate-driving forces and lithospheric stresses. We investigate the sensitivity of these tractions to sub-lithospheric viscosity variations by comparing shear tractions computed from a mantle flow model featuring laterally-varying lithosphere and asthenosphere viscosity with those from a model with l...

PURPOSE To evaluate treatment options for vitreomacular traction (VMT). METHODS A retrospective, consecutive case series and a literature search with Boolean search logic. A random-effects meta-analysis was conducted to combine the rates of VMT resolution per treatment. Patients from studies analyzed were placed into cohorts based on the treatment received. RESULTS CASE SERIES Zero of 10...

Purpose. To compare the stages of vitreous degeneration in patients with vitreomacular traction (VMT) and macular holes (MH). Methods. A retrospective study was performed analyzing stages of vitreous degeneration of eyes with VMT or MH using swept-source optical coherence tomography (SS-OCT) and spectral-domain optical coherence tomography (SD-OCT). An analogous review was performed on a contro...

Pneumatic vitreolysis (PVL) is the intravitreal injection of a small quantity of expansile gas for the purpose of achieving focal vitreomacular traction (VMT) release for eyes with symptomatic VMT, or inducing VMT release and closure of the macular defect for eyes with a small stage-2 macular hole (MH). Initially, there was limited interest in this technique upon its introduction for clinical t...

This retrospective quality control study aimed at comparing resolution in patients treated with intravitreal ocriplasmin (IVO) using two injection techniques, classical injection procedure (unguided) and targeted injection using a surgical microscope with a 30-gauge 1-inch needle (guided) for the treatment of focal VMT without macular hole. The two groups presented a statistically significant d...

BACKGROUND Spinal flexibility is determined preoperatively by manipulating the spine and assessing, radiographically, to what extent the amount of deformity reduces. Quantifying spinal flexibility is important when determining the approach to the planned operation in order to achieve the most optimal spinal correction and balance. Currently, supine traction radiography is a popular method used ...

INTRODUCTION Double dislocation of thumb metacarpal (MC) is a rare injury which may be secondarily complicated by growth plate injury in children. The management of floating 1st MC is also controversial since the treatment ranges from simple reduction to complex reconstruction surgeries. It is also important to understand the long-term results of different management strategies (close reduction...

I The forces required to detach the retina from the pigment epithelium and the subsequent structural changes were studied toith a device that produced retinal traction at different rates over localized, equatorial areas of freshly enucleated owl monkey and albino rabbit eyes. Sloio traction (0.2 to 0.8 mm. per minute) produced higher and larger retinal detachments and bigger tears in both types...
