CT-Guided Percutaneous Retrograde Drilling of Talar Osteochondrosis Dissecans: A Case-Report

Kuiper JWP, van Duijvenbode DC, Hoozemans MJM and Stavenuiter MHJ

Introduction: Osteochondrosis Dissecans is a non traumatic pathology, frequently observed in the ankle in young patients. Treatment methods include arthroscopic debridement, microfracturing and anterograde or retrograde drilling. Retrograde drilling does not damage the cartilage and has high success rates, but usually involves arthroscopy. The use of Computer Tomography (CT) for retrograde drilling is relatively unknown.
Patient: We present a case of Osteochondrosis Dissecans of the talus in a nine year old boy and describe a CT guided retrograde drilling method without the use of additional arthroscopy. After six months, the patient reported to have no pain and to be able to participate in sports activities again.
Discussion: This is the first study describing a patient treated with CT guided retrograde drilling of osteochondrosis dissecans without the use of arthroscopy. We believe that CT guided drilling has additional advantage to arthroscopic drilling, because it leaves the joint unharmed.
