RESUMEN
Objective To study the efficacy and safety of four surgical techniques of tuberculosis of lumbosacral junction retrospectively. Methods Between Jul 2001 and Jan 2013, 79 patients with lumbosacral spinal tuberculosis underwent surgery. Antituberculous chemotherapy and nutrition support prior to surgery were used for at least two weeks. 45 patients underwent single stage radical debridement, fusion and anterior instrumentation (A group). 18 patients underwent combined anterior and posterior spinal surgery (AP group), 10 patients underwent transpedicular drainage, posterior instrumentation, and fusion (P group), and 6 patients underwent anterior radical debridement (D group). All the patients were treated by antituberculous chemotherapy for 18 months and followed regularly. The operation duration, blood loss, clinical status, ESR, VAS, ODI, roentgenogram and 3D?CT were concerned to estimate the progress of tuberculosis. Radiographs were analyzed before surgery, immediately after surgery, and at the final follow?up examination to assess the result of anterior fusion and maintenance of correction. Results There was no inju?ry of blood vessel, ureter or cauda equina during surgery. The mean follow?up period was 23 months (range 18-42 months). No obvious loss of deformity correction was observed. There was no recurrence, no tuberculous peritonitis, and no incidence of im?potence or retrograde ejaculation in any of these patients. The average operating duration(min) were 144.31 ± 23.18, 444.72 ± 141.63, 351.50 ± 85.25, 90.00 ± 29.66, respectively; The average blood loss(ml)were 266.67 ± 104.45, 988.99 ± 488.26, 890.00 ± 306.23, 200.00±104.88, respectively; The average Pre?op VAS were 4.71±1.79, 5.22±1.48, 3.30±1.64, 2.50±1.52, respectively;The average last follow?up VAS were 0.89±0.68, 0.90±0.74, 1.00±0.63, respectively; The average Pre?op ODI(%)were 29.64± 7.85, 32.17±7.59, 28.20±4.26, 20.67±4.63, respectively; The average last follow?up ODI(%)were 5.09±3.59, 4.78±3.78, 4.80± 3.39, 4.00 ± 1.18, respectively; The average Pre?op lumbosacral angle(°)were 20.61 ± 4.92, 23.78 ± 5.84, 25.10 ± 4.28, 21.67 ± 4.27, respectively; The average Post?op lumbosacral angle were 27.17±3.66, 30.56±5.31, 32.10±4.01, 24.83±2.32, respectively;The average last follow?up lumbosacral angle were 23.89 ± 3.12, 27.00 ± 5.46, 29.00 ± 4.85, 23.33 ± 2.50, respectively. Conclu?sion Single stage anterior interbody fusion with anterior instrumentation worked effectively to stabilize lumbosacral junction (less invasive, short surgical duration, no injury of posterior column). Anterior interbody fusion combined with posterior instrumentation was recommended for patients with extensive bone defect and low iliocava junction.
RESUMEN
Objective To analyse the phenotypes of the drug?resistant tuberculosis, and investigate the outcomes of the individualize surgery and chemotherapy for these patients. Methods From January 2009 to June 2012, we retrospectively ana?lyzed 49 patients with drug?resistant tuberculosis spondylitis admitted in Southwest Hospital. 33 were initial cases and 16 were re?curring cases. All the 49 patients received individualized open operation or CT?guided percutaneous drainage and local chemother?apy depending on the characteristics of the focus. Individualized chemotherapy regimens were tailored for all patients according to the drug?resistant spectrum and all patients were followed up successfully at least 24 months. All the clinical data were collected and analyzed by statistical methods. Results Among the 49 patients, 14 were monoresistance tuberculosis, 11 were polyresis?tance tuberculosis, and 24 cases were multi?drug resistant tuberculosis. Frequence of the drug?restistance from high to low was Iso?niazid, Rifampicin, Streptomycin, Levofloxacin, Dipasic/Rifapentine, Ethambutol, Protionamide, Capreomycin, Paza?aminosalicy?late, and Amikacin. 43 patients received open operation and 6 patients received CT?guided percutaneous drainage and local che?motherapy. Time of the percutaneous drainage was (48±11) days (39-60 days), and all patients received Individualized chemother?apy with an average of (29.5±2.5) months (24-36 months) postoperatively. At the last follow?up, all patients had remarkable pain remission, 44 patients with paraplegia got slight or remarkable recovery and 17 patients with kyphosis got significant correction. Conclusion The main drug?resistant spectrums are Isoniazid、Rifampicin、Streptomycin、Levofloxacin. The individualized sur?gery combined with individualized chemotherapy made according to the drug?resistance is a feasible treatment for the drug?resis?tant tuberculosis especially the multi?drug resistant tuberculosis.
