Pain after hip replacement surgery may potentially hinder postoperative physiotherapy and early mobilization. Regional anesthesia of the lower limb appears to be effective for postoperative pain control in this setting and it has been shown that the lumbar plexus blockade provides high-quality analgesia, as the femoral nerve supplies the anterior hip joint capsule, as well as the proximal femur, the quadriceps, iliacus and pectineus muscles. High-impact journals are those considered to be highly influential in their respective fields. The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
