Targeted epiphysiodesis using needle arthroscopy.

ABSTRACT

Epiphysiodesis is performed to either temporarily or permanently close the physis. It is considered in the management of angular deformities or limb length discrepancies. There are various surgical techniques that have been described. The gold-standard remains the mechanical removal of the physis using drills, burrs, and curettes. This requires intraoperative imaging to guide surgery and invariably leads to the mechanical removal of healthy cancellous bone as well as physeal cartilage. We report on a case of 'targeted epiphysiodesis' using needle arthroscopy. In this technique, radiation exposure and unnecessary bone loss is minimal. Epiphysiodesis is achieved under direct vision using a 1.9 mm needle arthroscope with a successful outcome and no surgical complications noted.
