BACKGROUND AND PURPOSE The purpose of this study was to investigate the risk factors for new symptomatic vertebral compression fractures after vertebroplasty at the thoracolumbar junction. MATERIALS AND METHODS We conducted a retrospective analysis of 53 patients treated with percutaneous vertebroplasty at the thoracolumbar junction (T12, L1). The follow-up period was 15-27 months. The occurr...

This paper describes the treatment of the more vertical type of subcapital fracture of the neck of tile femur by reduction, nailing, and immediate wedge osteotomv, with fixation by a plate attached to the head of the nail. Ten cases are recorded. As in other clinics, it had been found that the results of treatment, by the standard Smith-Petersen technique, of subcapital fractures of the neck of...

INTRODUCTION Close reduction by extension-block K-wire fixation for acute mallet fracture is based on two sound orthopedic principles - stable arc splinting and early protected motion. Distal interphalangeal joint splinting is still the technique commonly used for mallet fractures with significant morbidity and only moderate functional outcome. CASE REPORT We have demonstrated here Ishiguro's...

During the process of rock deformation and failure, a significantly large number charge signals are generated as result fracture appearance crack expansion. The generation signal is comprehensive embodiment coal-failure behavior. study in fractured-rock failure great significance to prediction dynamic disasters such tunnel-engineering stability, slope instability earthquake. In this work, surve...

This biomechanical study is the first to compare 3 fixation methods-bilateral fixed-angle plate, modified anterior tension wiring, and cannulated lag screws with anterior tension wiring-in multifragmentary distal patella fractures. A T-shaped 3-part fracture simulating a multifragmentary articular distal patella fracture (AO/OTA 34-C2.2) was created in 18 human cadaver knee specimens. Three gro...

Fractured reservoirs are highly heterogeneous in both matrix and fracture properties, which results significant variations well production. Assessing quantifying the influence of fractures on fluid flow is essential for developing unconventional reservoirs. The complicated effects fractured depend geometry, distribution, can be reflected pressure transient testing. biggest challenge lies deline...

Gob-side entry retaining by roof cutting, a pillarless mining technique, plays critical role in maintaining continuous production, rapid connection, and enhancing the coal recovery rate fully mechanized top caving working faces. This technique stands as sustainable development method mining. The present research, set against backdrop of Yitang Coal Mine 100602 gob-side investigates influence ro...

OBJECTIVE To assess the relationship between impacted mandibular third molar presence and the risk for mandibular angle fracture with the effect of various positions of mandibular third molar and the risk of mandibular angle fracture. MATERIALS AND METHODS In the North Indian territory, a total of 289 patients with mandibular angle fractures were studied and evaluated for the possible relatio...

The application of roof-cutting and pressure-relief gob-side entry retention plays a critical role in controlling the stability surrounding rock at entry, easing continuity tension improving resource recovery ratio. excavation 360,803 airway Xinji No. 1 Mine is affected by intense mining 360,805 working face. Hence, to address problem airway, mass blast weakening theory was used this study anal...
