Pneumothorax complication of deep dry needling demonstration.

INTRODUCTION Pneumothorax is a well-recognised but rare adverse event related to acupuncture or deep dry needling (DDN) over the thorax. 2 This report of a pneumothorax resulting from DDN is unusual for a number of reasons: both the practitioner and the subject were doctors and both have contributed to this report; the practitioner was very experienced in DDN and had not knowingly caused such an event in the previous 45 years of practice and teaching DDN; the incident was captured on video and is presented online with this report (see online supplementary video). We hope that by reporting this event and review of the video recording we can suggest ways to reduce the risk of reoccurrence of such adverse events of DDN.
