Diagnosis and Treatment of Klebsiella Pneumoniae Combined with Enterobacter Cloacae in Lumbar Intervertebral Space Infection / 中山大学学报(医学科学版)

ABSTRACT

ObjectiveTo explore the clinical diagnosis and treatment of rare primary lumbar intervertebral space infection with Klebsiella pneumoniae and Enterobacter cloacae， and provide clinical experience for the diagnosis and treatment of this rare spinal infection. MethodsAn elderly male patient with low back pain and numbness in the left lower extremity for more than 7 months， which aggravated for more than 1 week， was diagnosed with lumbar disc herniation after laboratory and imaging examinations. After admission， the symptoms became acutely aggravated， and re-examination of lumbar enhanced MRI showed local enhancement at the posterior edge of the L3/4 intervertebral space. The VAS score was 9 points， and the lumbar JOA score was 6 points. A posterior lumbar interbody fusion of L3-L5 was performed， and L3/4 intervertebral disc specimens were collected during the operation for bacterial culture. ResultsBacterial culture results showed Klebsiella pneumoniae and Enterobacter cloacae infection. The patient was treated with sensitive antibiotics for 6 weeks after the operation， and the patient was cured during the follow-up of half a year after the operation. ConclusionFor middle-aged and elderly patients with clinical manifestations of acute severe low back pain or lower extremity pain， the possibility of spinal infection should be considered when routine laboratory and imaging examinations suggest lumbar degenerative diseases.
