Is kyphoplasty necessary?

We describe four cases of delayed union in female patients with severe osteoporotic vertebral fractures, which were treated in a similar but less costly method to kyphoplasty. Due to domestic regulations, inflatable tamps for kyphoplasty are not available to every clinical orthopedists in Japan. In our clinical experience of four cases of delayed lumbar spine union between 2009 and 2010, we performed vertebroplasty using a reduction and spreading prod (Oyamada prod) for fracture reduction and a pediatric uromatic balloon (Medicon Co.

Day zero ambulation under modified femoral nerve block after minimally invasive surgery for total knee arthroplasty: preliminary report.

Ambulation in the early postoperative period of total knee arthroplasty is crucial, in order to avoid complications and obtain preferable outcomes. Although a femoral nerve block can provide enough postoperative analgesia after total knee arthroplasty, falling, or other accidents due to motor paresis, are potentially adverse events in patients who have received a conventional femoral nerve block. We devised a modified femoral nerve block to spare voluntary knee extension ability, and clinically applied it to patients who received total knee arthroplasty under minimally invasive surgery.
