CHICAGO—Researchers in London say they have found an effective two-part treatment for microtears in the
hamstring: injections of the patient's
own blood and a steroid along with
"dry-needling," in which repeated needle punctures cause controlled internal bleeding in the injured area. Results of the study were presented today at the annual meeting of the Radiological Society of North America
(RSNA).

"By injecting the patient's own blood where it is needed at the site of a damaged tendon, we help the patient heal themselves," said lead researcher
Waseem A. Bashir, M.D., a radiologist at Royal National Orthopaedic Hospital and Ealing Hospital in London. "Blood contains many growth factors, and the injections have been shown to promote faster healing of certain injuries."
