A Strategic Protocol to Improve the Process and Outcomes of Two-stage Revision Total Hip Arthroplasty.

Two-stage revision total hip arthroplasty (THA) is the most commonly used treatment approach for deep prosthetic infection. However, in this approach the interval between the first and second stage tends to be prolonged. We devised a strategic protocol for improving the infection eradication rate and shortening the interval between the stages in two-stage revision THA.

Reduced blood loss and operation time in lumbar posterolateral fusion using a bipolar sealer.

Purpose: A bipolar sealer using Transcollation technology, a combination of radiofrequency energy and saline, can provide hemostasis at 100 °C, which is lower than that used in standard electrocautery. Previous studies of joint arthroplasty have shown that use of the bipolar sealer reduces blood loss and tissue damage during the operation. However, it is unknown whether a bipolar sealer reduces blood loss and tissue damage in lumbar posterolateral fusion (PLF) surgery.

[Therapeutic agents for osteoporotic pain].

Low back pain (LBP) is one of the major symptoms of elderly patients with osteoporosis. Pain control is important because pain hinders quality of life. The pathogenesis of the osteoporosis-related LBP is divided as follows, (1) vertebral fracture with bone fragility, (2) imbalance of sagittal alignment, (3) osteoporotic bone pain, (4) reduction of the descending pain inhibition system of serotonine, (5) psychological condition, (6) neural pain.
