Diverse biochemical and computational procedures and facilities have been developed to hybridize thousands of DNA clones with short oligonucleotide probes and subsequently to extract valuable genetic information. This technology has been applied to 73,536 cDNA clones from infant brain libraries. By a mutual comparison of 57,419 samples that were(More)
PURPOSE To discuss when and how to operate on thoracic and lumbar spine fractures. PATIENTS AND METHODS We retrospectively studied 77 consecutive patients with thoracic and lumbar spine fractures treated from 2000 to 2011; 28 patients experienced high-energy spinal trauma and 49 low-energy spinal trauma. Mean follow-up was 5 years (1-11 years). Surgical(More)
Hip fractures are associated with significant mortality and morbidity for the patients, more dependent residual status, and increased socio-economic cost. Many hip-fracture patients experience severe functional impairment, and most never recover their pre-fracture level of function. Current research has sought to identify the most effective treatments to(More)
PURPOSE Distraction osteogenesis is commonly used for limb deformities and reconstruction of bone defects with satisfactory outcome for the patients. However, it is associated with a risk of complications. The present study aims to assess the incidence of complications and to identify the risk factors that may predict distraction osteogenesis-related(More)
We retrospectively reviewed the medical records of 31 patients with periprosthetic hip infections attempting to evaluate the outcome of a two-stage revision protocol characterized by prolonged interim period (mean=9.2 months, range 8-12 months) prior to the final re-implantation. In 3 cases (9.6%) the 1st stage was repeated after a mean period of 12.3 weeks(More)
The increased incidence of motor vehicle accidents during the past century has been associated with a significant increase in brachial plexus injuries. New imaging studies are currently available for the evaluation of brachial plexus injuries. Myelography, CT myelography, and magnetic resonance imaging (MRI) are indicated in the evaluation of brachial(More)
The incidence of brachial plexus injuries is rapidly growing due to the increasing number of high-speed motor-vehicle accidents. These are devastating injuries leading to significant functional impairment of the patients. The purpose of this review paper is to present the available options for conservative and operative treatment and discuss the correct(More)
BACKGROUND The Rib Index, (RI), extracted from the double rib contour sign (DRCS) on lateral spinal radiographs to evaluate rib hump deformity, (RHD), in idiopathic scoliosis, (IS), patients, has been previously introduced. Although various papers using the RI have been published, no study on its reproducibility has been reported. The aim of this report is(More)
Distal femoral endoprosthesis (DFE) has become the optimal method of reconstruction in the skeletally mature patients treated for malignant bone tumor. Albeit literature has reported wide range of aseptic loosening in cemented components (6–32%), few authors showed that cement was not detrimental to long-term success of primary distal femoral implants(More)
The pre and postoperative rib-vertebra angles and Cobb angles in patients with idiopathic scoliosis pre and post operatively treated with full transpedicular screw constructs were compared. Eighteen patients had right thoracic curves while only two had a left curve. 7 curves were Lenke's type 3C, 6 type 5C, 4 type 1A, 3 type 6C and one type 2A. Convex side(More)
