ObjectiveTo evaluate the application and effectiveness of bilateral total hip arthroplasty and total knee arthroplasty in the treatment of severe inflammatory arthropathies. MethodsBetween September 2008 and September 2015, 31 patients with severe inflammatory arthropathies were treated with bilateral total hip arthroplasty and total knee arthroplasty. Of 31 cases, 22 were male and 9 were female with an average age of 30 years (range, 20 to 41 years); there were 15 cases of rheumatoid arthritis and 16 cases of ankylosing spondylitis with an average onset age of 14 years (range, 5-28 years); all 4 ankylosed joints were observed in 11 cases, 3 ankylosed joints in 2 cases, 2 ankylosed joints in 6 cases, 1 ankylosed joint in 1 case, and no ankylosed joint in 11 cases. Before operation, the hip range of motion (ROM) value was (17.82±28.18)°, and the knee ROM value score was (26.45±30.18)°; the hip Harris score was 29.64±11.58, and the hospital for special surgery (HSS) score was 27.07±11.04. The patients were grouped and compared in accordance with etiology and ankylosed joint. ResultsOne-stage arthroplasty was performed in 1 case, two-stage arthroplasty in 22 cases, three-stage arthroplasty in 7 cases, and four-stage arthroplasty in 1 case. The total operation time was 325-776 minutes; the total blood loss was 900-3 900 mL; the total transfusion volume was 2 220-8 070 mL; and the total hospitalization time was 21-65 days. The patients were followed up 12-94 months (mean, 51 months). The hip and knee ROM values, Harris score and HSS score at last follow-up were significantly improved when compared with preoperative ones (P < 0.05). The subjective satisfaction degree was good in 16 cases, moderate in 10 cases, and poor in 5 cases. Periprosthetic infection occurred in 2 cases (3 knees), joint stiffness in 3 cases (6 knees), joint instability in 1 case (1 knee), leg length discrepancy of > 2 cm in 2 cases, and flexion deformity of 10° in 1 case (1 knee). The hip and knee ROM values, Harris score and HSS score showed no significant difference between patients with ankylosing spondylitis and patients rheumatoid arthritis at last follow-up (P > 0.05). The hip and knee ROM values of the patients with ankylosed joint were significantly lower than those of patients with no ankylosed joint (P < 0.05); the Harris score and HSS score of the patients with ankylosed joint were lower than those of patients with no ankylosed joint, but no significant difference was found (P > 0.05). ConclusionA combination of bilateral hip and knee arthroplasty is an efficient treatment for severe lower extremities deformity, arthralgia and poor quality of life caused by inflammatory arthropathies. However, the postoperative periprosthetic infection and stiffness of knee are important complications influencing the effectiveness of operation.
ObjectivesTo systematically review the proportion of Tregs in peripheral blood of patients with ankylosing spondylitis (AS) and its relationship with Treg's diffrent phenotypes.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect case-control studies on peripheral Tregs of AS patients from inception to November 31st, 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 61 case-control studies involving 2 466 AS patients and 1 879 controls were included. The results of meta-analysis showed that: the proportion of peripheral Tregs of patients with AS was significantly lower than that of the normal control (SMD=−0.905, 95%CI −1.294 to −0.517, P<0.000 1), and the proportion of Tregs in the disease-active group was significantly lower than that in disease-inactive group (SMD=−0.928, 95%CI −1.431 to −0.425, P<0.000 1). The proportion of CD4+CD25+FOXP3+Tregs and CD4+CD25+CD127low/−Tregs were lower in AS patients than that in control subjects (SMD=−2.547, 95%CI −3.521 to −1.573, P<0.000 1; SMD=−0.709, 95% CI −1.056 to −0.362, P<0.000 1). The proportion of Tregs defined by CD4+CD25low/−FOXP3+ was higher in AS patients (SMD=0.683, 95%CI 0.161 to 1.206, P=0.01). There was no significant difference betweew other phenotypes of Tregs groups.roups.ConclusionsThe reduction of Tregs may be one of the important reasons for the occurrence and development of AS, which may provide a new approach for the diagnosis and treatment of AS.
Objective To explore the safety and effectiveness of one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation in the treatment of ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture. Methods A clinical data of 20 patients with ankylosing spondylitis kyphosis combined with acute thoracolumbar spine fracture, who were treated with one-stage posterior eggshell osteotomy and long-segment pedicle screw fixation between April 2016 and January 2022, was retrospectively analyzed. Among them, 16 cases were male and 4 cases were female; their ages ranged from 32 to 68 years, with an average of 45.9 years. The causes of injury included 10 cases of sprain, 8 cases of fall, and 2 cases of falling from height. The time from injury to operation ranged from 1 to 12 days, with an average of 7.1 days. The injured segment was T11 in 2 cases, T12 in 2 cases, L1 in 6 cases, and L2 in 10 cases. X-ray film and CT showed that the patients had characteristic imaging manifestations of ankylosing spondylitis, and the fracture lines were involved in the anterior, middle, and posterior columns and accompanied by different degrees of kyphosis and vertebral compression; and MRI showed that 12 patients had different degrees of nerve injuries. The operation time, intraoperative bleeding, intra- and post-operative complications were recorded. The visual analogue scale (VAS) score and Oswestry disability index (ODI) were used to evaluate the low back pain and quality of life, and the American spinal cord injury association (ASIA) classification was used to evaluate the neurological function. X-ray films were taken, and local Cobb angle (LCA) and sagittal vertical axis (SVA) were measured to evaluate the correction of the kyphosis. Results All operations were successfully completed and the operation time ranged from 127 to 254 minutes (mean, 176.3 minutes). The amount of intraoperative bleeding ranged from 400 to 950 mL (mean, 722.5 mL). One case of dural sac tear occurred during operation, and no cerebrospinal fluid leakage occurred after repair, and the rest of the patients did not suffer from neurological and vascular injuries, cerebrospinal fluid leakage, and other related complications during operation. All incisions healed by first intention without infection or fat liquefaction. All patients were followed up 8-16 months (mean, 12.5 months). The VAS score, ODI, LCA, and SVA at 3 days after operation and last follow-up significantly improved when compared with those before operation (P<0.05), and the difference between 3 days after operation and last follow-up was not significant (P>0.05). The ASIA grading of neurological function at last follow-up also significantly improved when compared with that before operation (P<0.05), including 17 cases of grade E and 3 cases of grade D. At last follow-up, all bone grafts achieved bone fusion, and no complications such as loosening, breaking of internal fixation, and pseudoarthrosis occurred. Conclusion One-stage posterior eggshell osteotomy and long-segment pedicle screw fixation is an effective surgical procedure for ankylosing spondylitis kyphosis combined with acute thoracolumbar vertebral fracture. It can significantly relieve patients’ clinical symptoms and to some extent, alleviate the local kyphotic deformity.

【摘要】 目的 探讨强直性脊柱炎合并脊柱骨折脱位的临床特点及手术治疗效果。 方法 2009年10月-2010年6月，共收治6例强直性脊柱炎合并脊柱骨折脱位患者，其中男5例，女1例；年龄38～76岁，平均48.6岁。下颈椎骨折脱位3例，2例为颈5-6、1例颈6-7；胸腰段骨折脱位3例，为胸10-11、胸11-12、胸12-腰1各1例。6例患者中除1例术前神经功能为Frankel分级 E级，其余5例均有不同程度的神经损伤。6例患者均行手术治疗，下颈椎骨折脱位采用前后联合入路复位及固定，胸腰段骨折脱位采用后路切开复位及椎弓根螺钉固定。术后观察手术节段内固定位置及骨融合情况，评估神经功能恢复情况，记录手术并发症。患者随访10~18个月，平均14.2个月。 结果 所有患者术后均未出现切口感染；脑脊液漏1例，换药对症处理3周后愈合。1例颈5-6骨折脱位患者行前路手术后第2天出现内固定移位，骨折椎再次脱位立即二次行前后联合入路复位固定术；3例术后神经功能由术前Frankel C级恢复至D级，2例无明显改善（术前均为A级），1例较术前加重（术前E级，术后为A级，经再次手术减压并康复治疗6个月后恢复至D级）。随访期间均达骨性融合，未出现内固定松动断裂移位现象。 结论 强直性脊柱炎脊柱骨折好发于下颈椎及胸腰段；对于下颈椎骨折脱位宜行前后联合入路复位固定，而胸腰段骨折宜行后路长节段椎弓根螺钉固定，术中应先充分减压后再精细复位，避免加重神经损伤。【Abstract】 Objective To explore the clinical characteristics of spinal fracture and dislocation in ankylosing spondylitis (AS) and its surgical treatment effect. Methods From October 2009 to June 2010, six cases with spinal fractures in AS underwent surgical treatment. There were 5 males and 1 female with an average age of 48.6 years (38-76 years old). The preoperative neural function of one case was grade E according to the Frankel classification and different degrees of neural damage could be found in other 5 cases. Three cases of lower cervical fractures underwent the operation with a combined posterior-anterior approach. Three cases of thoracolumbar fracture underwent the operation with posterior approach (posterior reduction, fixation with pedicle screws and bone graft). The situation of internal fixation and bone fusion was observed after operation, the neural function had been evaluated and the postoperative complications was recorded. Results All of the six patients were followed up for 10-18 months (mean 14.2 months). There was no incision infection. One patient with cerebrospinal fluid leakage was cured with conservative treatment for three weeks. One patient with C5-6 fracture and dislocation got anterior implant loosening and fracture-dislocation recurrence in the second day after the operation and underwent a combined posterior-anterior operation immediately. Three cases got remarkable neuronal function improvement after the operation. Two cases were remain primary situation. One case was aggravated from preoperative grade E grade to postoperative grade A and recovered to grade D after recovery treatment for 6 months. Bone fusion was achieved in all cases. There were no loosening and breakage of internal fixation in the later followed up. Conclusions Lower cervical and thoracolumbar spine are the usual locations of fracture in AS. A combined posterior-anterior surgical approach is effective for lower cervical fractures and posterior long-segmental reduction and the fixation is a desired select for thoracolumbar fractures.
Objective To explore the MRI features of juvenile-onset ankylosing spondylitis (JoAS) for improving the level of diagnosis and therapy. Methods MRI findings of JoAS in 25 patients confirmed by clinical and laboratory results between October 2010 and September 2014 were retrospectively analyzed. Results There were a total of 67 locations of lesion in the 25 cases, including 19 in sacroiliac joint, 21 in hip joint, 6 in ischial tuberosity, 6 in crista iliaca, 9 in knee joint, 4 in ankle joint, and 2 in foot. MRI showed 63 locations with bone marrow edema, 36 with joint effusion, 26 with bone destruction, and 19 with enthesitis. Conclusions Bone marrow edema is the most common MRI manifestation of JoAS, and the main bone destruction is middle axis joint. MRI is sensitive but not specific to lesions, so differential diagnosis is needed and helpful.
