THE MANAGEMENT OF THE ORTHOPAEDIC SEQUELAE OF MENINGOCOCCAL SEPTICAEMIA

Stanmore, England, 25 June 2010



Abstract

Meningococcal septicaemia from meningococcal infection is a devastating illness affecting children. Advances in medical management have reduced the mortality rate to approximately 15 to 20% and children who survive can develop late orthopaedic sequelae from growth plate arrests with resultant complex deformities. Our aim in this study was to review and analyze the case histories of a series of patients with late orthopaedic sequelae, all treated by the senior author. We describe a treatment strategy to address the multiple deformities that may occur in these patients.

Methods & Results Between 1990 and 2009, 12 patients were treated for late orthopaedic sequelae after meningococcal septicaemia by the senior author. There were 8 girls and 4 boys. All patients had lower limb involvement. 1 patient had involvement of the upper limb requiring treatment. Each patient had had a mean of 3 operations (range from 2 to 9). Methods of treatment included a combination of angular deformity correction, limb lengthening and epiphysiodesis. At final follow-up 9 of the 12 patients were skeletally mature. In 9 patients limb length discrepancy in the lower limb was corrected to within 1 cm, with normalization of the lower limb mechanical axis. Conclusion

Meningococcal septicaemia can lead to late orthopaedic sequelae due to growth plate arrests. Central growth plate arrests leads to limb length discrepancy, and partial growth plate arrests leads to an angular deformity. In addition, limb amputations may occur and there may be altered growth of the stump requiring further surgery. In cases of central growth arrest with limb shortening alone, limb equalisation is performed with limb lengthening procedures. In cases of partial growth arrests, angular correction is performed together with ablation of the affected growth plate. We recommend ablation of the affected growth plates at the initial surgery to prevent recurrence of angular deformity. Angular correction can be performed acutely, with a dome or transphyseal osteotomy; or gradually, with application of Ilizarov or Taylor Spatial frames. Severe deformities of the tibial plateau are treated by plateau elevation with bone graft augmentation. With the appropriate strategy deformities can be corrected and further lengthening procedures can be undertaken if necessary. Long-term follow-up of these patients is essential to recognise and treat any recurrence of deformity.
