    Abstract:
    PURPOSE: To assess the effectiveness of Brooks' posterior stabilisation and fusion for the unstable atlantoaxial joint due to congenital dysplastic dens and trauma. METHODS: We retrospectively studied records of 54 patients (36 males and 18 females; age range, 3-58 years) who underwent Brooks' posterior stabilisation procedure between March 1975 and December 1999, at the Catholic University of Korea Medical Center and Dong-Shin General Hospital, Seoul. A single-stranded Kirschner wire was used to stabilise the first 19 cases (thin wires in 12 cases and thick wires in 7), and double-stranded wires were used in the next 35 cases (thin wires in 4 cases and thick wires in 31). After surgery, patients were immobilised in bed with light Halter traction of the head, followed by cervical bracing. RESULTS: Fusion was observed by X-ray postoperatively at 15 weeks in 48 patients. Reduction was achieved in 3 luxation cases (including the single case of rotatory fixation). Brooks' fusion failed in 4 patients with dens fractures and 2 with dens anomaly. Four dens fractures in cases of successful Brooks' fusion in Brooks' fusion did not unite. Wire failure occurred in 4 cases of thin single-stranded wire fixation, namely, 2 cases of dens fractures and 2 of dens anomaly. CONCLUSION: Brooks' procedure is safe and has a high fusion rate when double-stranded strong wire fixation of the atlantoaxial joint is combined with meticulous bone grafting and subsequent cervical bracing.
