    Journal: Rev Chir Orthop Reparatrice Appar Mot; 2000 Oct; 86(6):608-15. PubMed ID: 11060435.
    Abstract:
    PURPOSE OF THE STUDY: We reviewed 30 cases of osteochondral lesions of the astragalar vault treated surgically. MATERIAL AND METHODS: Among the 30 patients, 17 participated in sports activities and 24 had a history of trauma. Mean delay to surgery was 10 months. Treatment included osteochondritis curettage and Pridie perforations. Direct access was used in 11 cases, malleolar osteotomy in 13 and arthroscopy in 6. Cancellous bone grafts were used in 6 cases. RESULTS: Mean follow-up was 3 years 7 months (minimum 2 years). All patients had an arthroscan at last follow-up. Evaluation of post-operative outcome was based on clinical assessment and arthroscan findings. Surgical treatment provided very good results in 75 p. 100 of cases with pain relief and improved walking distance. DISCUSSION: Our cases pointed out the important contribution of the FOG (Fracture Osteonecrosis Geode) classification to pathogenic and prognostic analysis. The Berndt and Harty classifications were not found to be useful. CONCLUSION: In case of localized necrosis, we propose arthroscopic perforation curettage. In case of bone loss, a direct cancellous graft may be used.
