Objective To evaluate the clinical outcomes of external fixator with lumbopelvic distraction spondylodesis in treatment of vertically unstable pelvic fractures. Methods From January 2008 to March 2009, 9 patients (4 males and 5 females) with a vertically unstable pelvic fracture were treated with modular external fixator with lumbopelvic distraction spondylodesis. According to the classification of Tile, 9fractures were classified as type C. This fixation construct comprises a vertical lumbopelvic distraction component which fixed L4.5 and the posterior superior iliac spine and a transverse fixation which fixed anterior iliac spine with external fixator. Results All patients were followed up 12-18 months after surgery, with an average of 14.3 months. Postoperative X-ray showed satisfactory reduction of pelvic fracture. Pelvic fractures healed in all patients without loss of reduction 3-6 months after operation. According to Matta reduction evaluation criteria, 6 patients were excellent and 3 good. For the two patients with sacral neurological injuries,appropriate surgical decompression was performed to improve the symptom and minimize the deformity. No iatrogenic complications of neurovascular injury occurred. Patients now walk unassistedly without pain in the waist or legs, and with no shortening of lower limbs or claudication. By considering symptom and satisfactory scores, the Majeed functional assessment revealed that seven patients had excellent results and two good at one year. Conclusion External fixator with lumbopelvic distraction spondylodesis that allowed early mobilization and ambulation, with general applicability and definite safety, is an effective surgical technique for the treatment of vertically unstable pelvic fracture.

OBJECTIVETo analyze the clinical characteristics of elderly patients with spinal tuberculosis and explore its clinical effects with anti-TB drugs alone.

METHODSFrom January 2008 to July 2010, the data of 36 patients with spinal tuberculosis underwent conservative treatment of anti-TB drugs alone were analyzed. There were 19 males and 17 females with an average age of 73.5 years (ranged, 60 to 85). All patients were in the active phase with high ESR and CRP levels and were treated with 3HRZE/6-9HRE (course from 9 to 12 months). According to clinical symptoms, chemical examination, radiological image to adjust drug and depending on VAS score to evaluate pain.

RESULTSAll the patients were followed up from 8 to 24 months with an average of 15 months. Tuberculose of 31 patients healed after chemotherapy from 9 to 12 months and ESR and CRP recovered normally. Levofloxacin and para-amino salicylic acid were used in 4 cases because of 4 cases occurred drug fast for RFP or INH, after 15 months, their obtained healing. Symptom of 1 case got worse during chemotherapy, and surgical treatment were performed, after 3 months, ESR and CRP recovered normally, X-ray and CT showed spinal osteosclerosis and fusion without significant kyphosis and internal fixation loosening. Cobb angle was respectively(17.6+/-2.3) degrees, (18.1+/-2.7) degrees before treatment and last follow-up (P>0.05). MRI showed abscess was absorbed and spinal inflammation subsidised. VAS score was respectively 6.5+/-1.7, 1.4+/-0.5 before treatment and last follow-up (P<0.05). Seven patients had complications relating with drug adverse reaction,after discontinuation and treated with clinical symptom,the patients recovered normally.

CONCLUSIONAnti-TB drugs alone can obtain satisfactory effects in treating early senile spinal tuberculosis, but strict supervision and individual administration should not be disregardful.
