Percutaneous Reduction and Injection of Norian Bone Cement for the Treatment of Displaced Intra-articular Calcaneal Fractures

Abstract

The treatment of intra-articular calcaneal fractures remains controversial. Although open reduction and fixation are favored by many authors, increased risk of soft tissue complications makes this method of treatment a challenge. Conversely, conservative treatment frequently leads to severe functional impairment and disability. Percutaneous surgical techniques have been employed to reduce the incidence of soft tissue complications but carry the risk of inadequate reduction and fracture stabilization. Norian SRS bone cement is an injectable calcium phosphate cement. Recent clinical studies have demonstrated the safe use of Norian SRS bone cement to augment standard plate fixation of calcaneal fractures. The authors describe their method of combining a percutaneous technique of fracture reduction with stabilization using Norian SRS bone cement. A total of 10 patients with 12 displaced intra-articular calcaneal fractures underwent this method of treatment. All 12 cases achieved adequate reduction on postoperative radiographs. Full weight bearing was started at 1 month postoperation, and none of the cases demonstrated loss of reduction on serial postoperative radiographs. No wound complications or cement-related soft tissue reactions were encountered. A 6-month assessment using the visual analog scale, the Maryland Foot Score, and the Short Form 36 general health survey showed encouraging results. Early results of treating displaced intra-articular calcaneal fractures using this method of a percutaneous technique of fracture reduction combined with Norian SRS bone cement stabilization are encouraging and promising.
