A high degree of vigilance is warranted for a spinal infection, particularly in a patient who has undergone an invasive procedure such as a spinal injection. The average delay in diagnosing a spinal infection is 2-4 mo. In our patient, the diagnosis of a spinal infection was delayed by 1.5 mo.
A 60-year-old male patient with a 1-year history of right-sided lumbar radicular pain failed conservative treatment. Six weeks to prior to surgery he received a spinal injection, which was followed by increasing lumbar radicular pain, weight loss and chills. This went unnoticed and surgery took place with right-sided L4-L5 combined microdiscectomy and foraminotomy via a posterior approach. The day after surgery, the patient developed left-sided lumbar radicular pain. Blood cultures grew Staphylococcus aureus (S. aureus). Magnetic resonance imaging showed inflammatory aberrations, revealing septic arthritis of the left-sided L4/L5 facet joint as the probable cause. Revision surgery took place and S. aureus was isolated from bacteriological samples. The patient received postoperative antibiotic treatment, which completely eradicated the infection.
The development of postoperative lower back pain and/or lumbar radicular pain can be a sign of a spinal infection. A thorough clinical and laboratory work-up is essential in the preoperative evaluation of patients with spinal pain.
Core Tip: This is the case report of a 60-year-old male patient with right-sided L4-L5 Lumbar disc herniation who underwent right-sided transforaminal injection with no improvement and a decision was made to carry out surgery. On day 1 postoperatively he developed excruciating left-sided lumbar radicular pain. Investigations and retrospective analyses demonstrated left-sided septic L4-L5 facet joint arthritis caused by Staphylococcus aureus, most probably as a result of the spinal injections 6 wk prior to surgery. The infection was successfully treated with revision surgery and antibiotic therapy.
