Surgical treatment of postoperative deep wound infection after posterior lumbar interlumbar fusion of the lumbar stenosis / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To study surgical treatment for the deep wound infections after the operation of posterior lumbar interlumbar fusion (PLIF) in lumbar spinal stenosis.</p><p><b>METHODS</b>From December 2005 to December 2010,10 patients with the deep wound infection of the PLIF were analyzed retrospectively, including 4 males and 6 females, with a mean age of 52.8 years (ranged from 34 to 70 years). All the patients were treated with debridement and the drainage. The sensitive antibiotics were used. The VAS score, erythrocyte sedimentation rate (ESR), C reactive protein (CRP), and JOA lumbar score were used to compare the clinical results pre-and post-operation.</p><p><b>RESULTS</b>All the patients were followed up, and the mean duration was 24 months (ranged from 19 to 28 months). One patient developed to an intervertebral space infection and the cage was removed. One patient suffered a radical central nerve system infection and died after the debridement. Other 8 patients got a good clinical result. The VAS score decreased from preoperative 8.0 +/- 0.4 to postoperative 2.8 +/- 0.3; JOA score improved from preoperative 10.30 +/- 3.02 to postoperative 24.10 +/- 2.85; ESR decreased from preoperative (85.0 +/- 17.0) mm/h to postoperative (14.0 +/- 6.0) mm/h; both CRP and WBC decreased from preoperative (73.5 +/- 14.3) mg/L, (11.1 +/- 1.8) x 10(9)/L to postoperative (5.1 +/- 1.1) mg/L, (7.4 +/- 0.5) x 10(9)/L respectively.</p><p><b>CONCLUSION</b>Treatment of patients with deep wound infections after PLIF with debridement, drainage, and sensitive antibiotics could get a good long-term clinical result, which is important to treat the patients with high-risk factors. Early diagnosis and operation is the key to deal with the patients with deep wound infections after PLIF.</p>
