Background: The choice of treatment of dorso-lumbar spinal fractures in the absence of neurological deficit depends on the classification and severity of injury. In the conventional open approach with posterior pedicle screw fixation, detachment of the Para spinal muscles may be required. In addition, this open approach may be disadvantaged by prolonged operative time, increased intraoperative ...

PURPOSE The use of new headless compression screws (HCSs) for scaphoid fixation is growing, but the nonunion rate has remained constant. The aim of this study was to compare the stability of fixation resulting from four modern HCSs using a simulated fracture model to determine the optimal screw design(s). METHODS We tested 40 fresh-frozen cadaver scaphoids treated with the Acumed Acutrak 2 mi...

BACKGROUND The thoracolumbar AO type A3 fracture is an incomplete burst fracture, which affects one vertebral body endplate. The objective of this study was to determine which of two minimal invasive techniques was more suitable for A3 fractures based on clinical and radiographic results. MATERIAL AND METHODS We studied 112 patients with A3 subtype fractures without neurological deficits. A tot...

In this mini-review, we summarize the evidences of lamellar twisting in the birefringent banded polymer spherulites demonstrated by various characterization techniques, such as polarized optical microscopy, real-time atomic force microscopy, micro-focus wide angle X-ray diffraction, etc. The real-time observation of lamellar growth under atomic force microscopy unveiled the fine details of lame...

Mini-implants and miniscrews are commonly used in orthodontics to provide additional temporary intraoral anchorage. Partial osseointegration represents a distinct advantage in orthodontic applications, allowing effective anchorage to be combined with easy insertion and removal. This article reports the histomorphometric findings of the osseointegration of bracket screw bone anchors (BSBAs). In ...

screw-retained implant restorations have an advantage of predictable retention as well as retrievability, and obviate the risk of excessive sub-gingival cement commonly associated with cement retained implant restorations. screw-retained restorations generally have screw access holes, which can compromise esthetics and weaken the porcelain around the holes. the purpose of this study is to descr...

Treatment options for mallet finger fracture are primary conservative such as splint or cast [2]. Splints or casts immobilize musculoskeletal injuries while alleviating pain and promoting healing. However, these interventions differ in their technique, indications, benefits, and risks. Operative treatment is indicated in case of fractures involving more than one third of the articular surface a...
