强直性脊柱炎患者血清IFN一百的变化

为探讨免疫调节异常在强直性脊柱炎(AS)发病机制中所起的作用,采用酶联免疫法(ELISA)检测35例AS患者的血清IFN—γ百含量,并以30例健康体检者为正常对照。结果显示AS患者血清IFN—γ(33.16±12.23pg/mL)明显低于正常对照组(55.16±30.75pg/mL),差异有显著性意义(P<0.01)。提示T淋巴细胞功能异常可能参与AS的发病过程。

全髋关节置换术治疗强直性脊柱炎致髋关节强直的疗效及康复锻炼的意义

Objective To investigate the clinical effects of total hip arthroplasty (THA) for bony ankylosis in patients with ankylosing spondylitis and the significance of postoperative rehabilitation. Meth-ods From October 1998 to May 2007, 28 patients (46 hips) suffered from ankylosing spondylitis with hip bony ankylosis underwent THA. There were 27 males, 1 female, with the mean age of 38.9 years (range 22 to 58 years). Posterior lateral hip incision was performed in 34 hips, and modified anterior lateral combined with lateral hip incision in 12 hips. Forty hips applied cementless THA and 6 hips applied mixed THA. Har-ris scores, VAS scores and total hip range of motion in all patients were compared pre-and postoperatively to evaluate the clinical effects. Results All patients were followed up from 10 months to 64 months, with the mean time of 38.2 months. No paralysis, decubitus, and lung infection were found. Joint dislocation hap-pened in 1 case 2 weeks after operation, and was cured with close reduction. Heterotopic bone formation with Brooker Ⅰ was found in 6 hips and Brooker Ⅱ in 2 hips. Harris score increased from 28.3±10.3 preop-eratively to 82.7±7.6 postoperatively. VAS score changed from 3.5±1.4 preoperatively to 3.8±1.8 postopera-tively, and no significance was found. The hip movement range increased from 15.6°±9.3° preoperatively to 133.7°±17.6° postoperatively. Bony ankylosis in all patients disappeared and the hip function improved sig-nificantly after operation. Conclusion THA is the optimal method to treat the ankylosing spondylitis with hip bony ankylosis. Early rehabilitation is necessary to improve hip function.     

Combined anterior and posterior surgery for treatment of cervical fracture-dislocation in patients with ankylosing spondylitis

To discuss the pathological characteristics of cervical spinal fracture complicating ankylosing spondyli-tis-(AS) and the effect of combined anterior and posterior operation. Methods: Eighteen AS patients with traumatic cervical fracture-dislocation were treated operatively from January 2000 to January 2006. The symptom duration of AS was 14.5 years on average. Three cases had undergone osteotomy in lumbar spine. There were 4 cases of Grade A, 3 cases of Grade B, 9 cases of Grade C and 2 cases of Grade D accord-ing to Frankel's score. There were 15 cases of Grade Ⅲ dislocation and 3 cases of Grade Ⅱ. All patients underwent surgical procedures by combined anterior and posterior approach.Results: There were 4 anterior-posterior procedures, 8 anterior-posterior-anterior procedures and 6 posterior-an-terior procedures. Seven patients had one stage operation and 11 cases underwent two stage surgeries. There was certain extent of neorological improvement in 14 incomplete paraplegic patients, but no improvement in 4 complete paraplegic patients. The follow-up period was 21.2 months on average and the time for bone fusion was 3.6 months. There were 4 complications during operation and a long-term complication in follow-up. Conclusions: The study suggests that anterior com-bined with posterior approach makes the spine stable and relieves the pressure immediately. It is a reasonable surgical strategy for treatment of cervical spinal fracture-dislocation with AS.
