Debridement, internal fixation, and reconstruction with titanium mesh for the surgical treatment of lumbar tuberculosis via a posterior-only approach in adults / 中国骨伤

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the clinical effects, indications and key techniques of debridement, internal fixation, and reconstruction with titanium mesh in lumbar tuberculosis via a posterior-only approach in adults.</p><p><b>METHODS</b>The clinical data of 26 patients with monosegment lumbar tuberculosis treated with surgery from March 2012 to March 2014 was retrospectively analyzed. Among them, 15 cases were male and 11 cases were female, and patients' age ranged from 21 to 68 years old (average, 44.7 years old). All patients suffered from back pain and/or pain with radiation to the legs. The clinical efficacy was evaluated based on the complications, erythrocyte sedimentation rate (ESR), imaging examination, and back and leg pain score of visual analogue scale (VAS).</p><p><b>RESULTS</b>All operations were successful in 26 patients with an average operation time of (2.4±0.8) h (range from 2 to 4 h), with an average blood loss of (320±86) ml(range from 200 to 700 ml) .VAS was decreased from (5.7±1.4) points preoperatively to (1.6±0.5) points 2 weeks postoperatively (<0.01); and ESR was decreased from (42.8±10.4)mm/h preoperatively to (12.1±5.6)mm/h 3 months after surgery (<0.01). All the patients were followed up for 24 to 48 months with an average of(28.3±5.8) months. One patients suffered from the recurrence of TB and sinus tract formation at 2 months after surgery, and was cured by stronger anti-tuberculosis drugs, local debridement with drainage, and sinus tract healed at 3 months after operation. All intervertebral bone graft obtained fusion within 1 year after operation and no local recurrence of TB was found at final follow-up.</p><p><b>CONCLUSIONS</b>Debridement, internal fixation, and reconstruction with titanium mesh via a posterior-only approach is a effective and safe method for the treatment of monosegment lumbar tuberculosis, especially for the patients with secondary spinal stenosis.</p>
