Non-Invasive, Low-Complication Treatment Helps Heal Fractures
ROSEMONT, Ill., Nov. 2 /PRNewswire-USNewswire/ -- When fractured bones fail to heal, a serious complication referred to as "nonunion" can develop. This occurs when the process of bone healing is interrupted or stalled. According to a new study published in the November 2009 issue of The Journal of Bone and Joint Surgery (JBJS), certain cases involving nonunions respond very well to shock-wave therapy. Researchers say this non-invasive treatment is equally effective as surgery when it comes to healing the bone.
"We found that extracorporeal (external to body) shock-wave therapy was just as effective as surgery in helping to heal and repair nonunions," said lead author of the study Angelo Cacchio, MD, a physiatrist who conducted the study with colleagues from the Division of Orthopaedic Surgery and the Department of Physical Medicine and Rehabilitation at San Salvatore Hospital in L'Aquila, Italy.
Study authors say sparse surrounding vascular tissue and limited blood supply can lead to a nonunion and can subsequently delay or prevent healing. This complication -- a nonunion -- often is very difficult to treat.
Dr. Cacchio and his colleagues analyzed data from 126 patients who had nonunions of the femur (thigh bone), tibia (shinbone), ulna (forearm) or radius (forearm). Patients were randomly assigned to one of three groups and all patient outcomes were evaluated from 2001 to 2004. The patients in the three groups had similar demographic characteristics and similarly timed and developed nonunions. The first two groups of patients received surgery to help repair their fracture. The third received four shock-wave therapy sessions at weekly intervals, with 4000 impulses per session.
The study found that shock-wave therapy:
