INTRODUCTION

  • Vertebral osteomyelitis is usually treated by anterior decompression and stabilization but this approach may not be convenient especially in elderly patients with pulmonary co-morbidities.
  • On the other hand, surgeons may hesitate to perform posterior debridement and stabilization with due to the concerns about contamination of the implants and difficulty in debridement and reconstruction of anterior column.
slide3

PURPOSE

  • To evaluate posterior subtotal vertebrectomy for vertebral osteomyelitis in elderly patients with pulmonary comorbidity.
  • Eleven elderly patients with chronic lung diseases were treated by posterior vertebral column resection and instrumentation to manage their thoracic vertebral osteomyelitis.

PATIENT SAMPLE

slide4

METHODS

  • Therewere 7 femaleand 4 malepatientswith a meanage of 67.3 (range; 50 to 83) years at the time of operation.
  • Etiologicaldiagnoseswere
    • spinaltuberculosis in 5 patients
    • nonspecificspondylodiscitis in 6 patients (5 staphylococcus, 1 E. Coli).
  • Surgicaltechnique:
    • Afterplacement of pediclescrews, hemilaminectomyandcostotransversectomywereperformed at fracturelevelvia a unilateralapproach. Then, posteriordecompressionandsubtotalvertebrectomywasaccomplished. Titanium mesh cagewasplacedthroughthesameincision. Contalateralposteriorelementswerepreservedforfusion.
slide5

METHODS

  • Preoperative, postoperative and 2 years follow-up A-P and lateral radiographies were evaluated in terms of local kyphosis angle and fusion rates.
  • Hospital charts were evaluated in terms of complications and laboratory analysis (sedimentation rate and C-reactive protein).
slide6

RESULTS

  • There were 10 two-level and 1 four-level resections in thoracic spine.
  • The mean operation time was 7.5 hours.
  • The average blood loss was 935 ml.
  • The average number of instrumentation level was 7.5.
  • Average follow-up was 33 (24 to 60) months.
slide7

RESULTS

  • The mean preoperative local kyphosis angle was 24.7 degrees; it was improved to 6.3 degrees at the early postoperative period and it was maintained at 7.7 degrees at the latest follow-up.
  • Nine patients with partial neurological deficit had significant improvement.
  • Postoperative deep infection in one and hematoma in one patient responded well to debridement surgery.
  • None of the remaining patients required revision surgery for recurrence of infection or implant failure or pseudoarthrosis.
slide9

CONCLUSION

  • Subtotal posterior vertebrectomy enabling decompression of the spinal canal and reconstruction of the resected vertebral segment was an efficient technique.
  • This procedure eliminated the need for anterior approach which might have caused significant morbidity.
