Postoperative wound complications, including surgical site infections, which frequently occur in the course of management of musculoskeletal sarcomas, sometimes necessitate repeat surgeries, including amputation, and may result in a prolonged healing time, prolonged hospital stay, or fatal outcome. A comprehensive understanding of surgical site infections associated with specific diseases is needed to reduce the risk. ⋯ The incidence rate of surgical site infection was larger than that associated with conventional orthopedic surgeries, such as osteosynthesis, spine surgery, or arthroplasty. Surgical site infections remain a critical and frequent complication of surgical treatment of soft-tissue malignancies and often result in prolongation of hospital stay. Although practical options to prevent surgical site infections seem quite limited, the present data provide a rationale for perioperative evaluation in patients at a high risk of surgical site infections.

Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used in clinical situations to reduce inflammation and pain. Percutaneous administration is one of the routes mainly used in Japan to deal with the pain from acute injuries, to chronic pain such as chronic low back pain and osteoarthritis (OA). There have been no studies that report the effect of percutaneous administration of NSAIDs on chronic pain in animal models. This study aimed to investigate the effect of percutaneously absorbed NSAIDs on a rodent model of OA. ⋯ Suppression of proinflammatory cytokines and c-Fos expression by clinically used NSAIDs suggests that their percutaneous administration may have an analgesic effect for treating chronic pain at a molecular level.
