Tranexamic acid reduces blood loss in cemented hip arthroplasty: a randomized, double-blind study of 39 patients with osteoarthritis.

Background: Tranexamic acid has been found to reduce blood loss and the need for blood transfusions in knee arthroplasty. In hip arthroplasty, the benefit of tranexamic acid is not as clear.

Patients And Methods: In a randomized, double-blind study, 39 patients with primary cemented hip arthroplasty for osteoarthritis were divided into two groups; one receiving tranexamic acid and the other not receiving it.

Fixation of syndesmotic ruptures in 38 patients with a malleolar fracture: a randomized study comparing a metallic and a bioabsorbable screw.

Objectives: To compare the performance of a metallic and a biodegradable screw in the fixation of tibia-fibula syndesmotic ruptures.

Design: A randomized, prospective, and blinded study.

Setting: Central hospital, Department of Surgery.

Twenty-year results of the Evans operation for lateral instability of the ankle.

Twenty-four patients (25 ankles), operated on using the static modification of the Evans tenodesis for lateral instability, were evaluated 19 to 21 years after surgery. Twelve of the patients (12 ankles) had excellent results, seven patients (eight ankles) had good results, three patients (three ankles) had fair results, and two patients (two ankles) had poor results. The subjective results had no clear correlation to the stress radiographs, which showed minor or moderate anterior talar translation in 10 ankles.

Blood clots in vessels surrounding symptomatic nerve roots in disc herniation patients: a pilot study.

Mechanical compression and biochemical influences, e.g. by various inflammatory cells and mediators, have been suggested to be involved in the pathophysiology of sciatica.

Poor correlation of clinical signs with patellar cartilaginous changes.

PURPOSE: There is controversy between the symptoms and signs of chondromalacia. Patellar chondromalacia has several clinical tests, whose reliability as a parameter of chondral damage is unclear. The purpose of this prospective study was to correlate the sensitivity, specificity, predictive values and accuracy of clinical patellar tests with the findings at arthroscopy.
