Screw Fixation as the Primary and Definitive Treatment of an Isolated Uncommon Fracture of the Anterior Margin of the Distal Tibia.

Tibial plafond fractures constitute one of the most challenging fracture types while they are commonly associated with soft tissue damage and severe bone comminution. We present the clinical outcomes of screw fixation as the initial and definitive treatment of an isolated uncommon fracture of the anterior margin of the distal tibia. This is a case of an uncommon type of fracture of the distal tibia.

Integrity of posterior retinaculum after displaced femoral neck fractures.

Introduction: It is widely thought that the posterior retinaculum is intact only in relatively undisplaced intracapsular fractures, and interruption of the arterial flow through the retinacular arteries to the femoral head is the main cause of avascular necrosis after fracture of the neck.

Patients: In order to test the hypothesis that the posterior retinaculum is torn after a displaced femoral neck fracture, 112 patients (45 males and 67 females), 75 years old on average, underwent a hemiarthroplasty for a displaced femoral neck fracture. There were 71 Garden type III and 41 Garden type IV fractures.

Effects of choline-deprivation on paracetamol- or phenobarbital-induced rat liver metabolic response.

Choline is an essential nutrient that seems to be involved in a wide variety of metabolic reactions and functions in both humans and rodents. Various pathophysiological states have been linked to choline deprivation (CD). The aim of the present study was to determine the effect of CD upon biochemical, histological and metabolic alterations induced by drugs that affect hepatic functional integrity and various drug metabolizing systems via distinct mechanisms.

Study of trunk asymmetry in normal children and adolescents.

The scoliometer readings in both standing and sitting position of 2071 children and adolescents (1099 boys and 972 girls) aged from 5 to 18 years old were studied. The angle of trunk rotation (ATR) was measured, in order to quantify the existing trunk asymmetry. Children and adolescents were divided in two groups according to the severity of trunk asymmetry.

Quality of life after surgical decompression of lumbar spinal stenosis with and without instrumentation.

The aim is to evaluate the influence on quality of life of surgical decompression with and without instrumentation in lumbar spinal stenosis. Twenty three patients, (16 women, 7 men) with a mean age of 62,8 years old (range 44-80) who underwent a surgical decompression for lumbar spinal stenosis filled the SF-36 questionnaire pre- and postoperatively, during the follow up period which was at a mean value of 42 months (range 6 to 50 months). Spinal stenosis was degenerative in 18 patients and as a consequence of spondylolisthisis in 5.

Intervertebral disc biomechanics in the pathogenesis of idiopathic scoliosis.

The aim of the present study is to investigate whether the deformation of the intervertebral disc contributes to the progression of idiopathic scoliotic curves. In the standing posteroanterior x-rays of 92 scoliotic curves the following readings were obtained: Cobb angle (CA), apical vertebral rotation (AVR), apical vertebral wedging (AVW) and the adjacent to the apical vertebra Upper (UIVDW) and Lower (LIVDW) InterVertebral Discs Wedging. The statistical analyses included inter - intraobserver reliability test, descriptives, monofactorial linear regression and Pearson correlation coefficient, with p<0.
