【Abstract】 Objective To explore the effectiveness of multiple joint arthroplasty in treating lower limb joint disease. Methods Between January 2000 and December 2007, 5 patients with lower limb joint disease (three or more joints were involved) were treated with total hip and knee arthroplasty. There were 3 males and 2 females, aged from 27 to 59 years (mean, 41.8 years). Two patients had ankylosing spondylitis and 3 had rheumatoid arthritis, whose hip and knee joints were involved. Four patients lost the ability of walking preoperatively, 1 patient could only walk with crutch. The Harris score was 24 ± 24 and the Hospital for Special Surgery (HSS) score was 28 ± 15. All patients underwent multiple joint arthroplasty simultaneously (2 cases) or multiple-stage (3 cases). Results Wounds healed by first intention in all patients. In 1 patient who had dislocation of the hip after operation, manipulative reduction and immobilization with skin traction were given for 3 weeks, and no dislocation occurred; in 2 patients who had early sign of anemia, blood transfusion was given. All patients were followed up 46-140 months with an average of 75 months. The patients could walk normally, and had no difficulty in upstairs and downstairs. The stability of the hip and knee was good, and no joint infection or loosening occurred. The Harris score was 88 ± 6 at last follow-up, showing significant difference when compared with the preoperative score (t=8.16, P=0.00); the HSS score was 86 ± 6, showing significant difference when compared with the preoperative score (t=13.96, P=0.00). Conclusion Multiple joint arthroplasty is an effective treatment method in patients with lower limb joint disease, which can significantly improve life quality of patients.
ObjectiveTo understand the self management status of patients with ankylosing spondylitis (AS). MethodsSixty inpatients and outpatients with AS in the Department of Rheumatology between December 2011 and December 2012 were selected as the study subjects by judgment sampling method. A self-made questionnaire was used for investigation. ResultsThe self-management skills of 10.0% of the patients were poor, 78.3% were moderate and 11.7% were fine. The self-management skills of functional training and keeping healthy lifestyle were relatively poor. The factors with a score from the highest to the lowest were:the mental self-management, symptom management, keeping healthy lifestyle, and the self-management of functional training. ConclusionsThe self-management skills of patients with ankylosing spondylitis range from moderate to relatively poor. Our results suggest that cultural factors and the course of disease may be the main influence factors for self-management skills of patients. Clinical medical personnel should know the situation of patients sufficiently, improve the processes of health education and take corresponding intervention measures to the lack of self management ability. By the above ways, we can improve the compliance obedience and the self-management skills of patients, then the patients' condition and living quality will be greatly improved.
ObjectiveTo introduce the application of Photoshop CS16.0 (PS) software in preoperative osteotomy design of ankylosing spondylitis kyphosis (ASK), and to investigate applied values of the preoperative design. MethodsBetween March 2009 and March 2013, 21 cases of ASK were treated through preoperative osteotomy design by using PS software. There were 16 males and 5 females, aged from 23 to 50 years (mean, 34.2 years). The deformity included thoracolumbar kyphosis in 14 cases, thoracic kyphosis in 2 cases, and lumbar kyphosis in 5 cases. The ultimate osteotomy angle of preoperative plans and the location and extent of osteotomy were determined by the osteotomy design, which guided operation procedures of the surgeon. The actual osteotomy angle was obtained by measuring Cobb angle of osteotomy segment before and after operation. The sagittal parameters of spine and pelvis including global kyphosis (GK), lumbar lordosis (LL), sagittal vertical axis (SVA), pelvic incidence (PI), pelvic tilt (PT), and chin brow-vertical angle (CBVA) were measured at preoperation, at 1 week after operation, and last follow-up. The clinical outcomes were assessed by simplified Chinese Scoliosis Research Society-22 (SRS-22) questionnaire and Oswestry disability index (ODI). ResultsNo complications occurred in the other cases except 1 case of dural tear during operation and 1 case of nerve injury after operation, and primary healing of incision was obtained. All patients were followed up 14 to 45 months (mean, 26.3 months). The SRS-22 and ODI scores at 1 week after operation and last follow-up were significantly improved when compared with preoperative scores (P<0.05), but no significant difference was found between at 1 week and last follow-up (P>0.05). The preoperative planned osteotomy angle and the postoperative actual osteotomy angle were (34.2±10.5)° and (33.7±9.7)° respectively, showing no significant difference (t=0.84, P=0.42). The CBVA, GK, SVA, PT, and LL were significantly improved when compared with the preoperative values (P<0.05), but no significant difference was found between at 1 week and last follow-up (P>0.05). At last follow-up, no failures of internal fixation was found, and bony fusion was obtained. ConclusionThe preoperative osteotomy design by using PS software can precisely recover the spinal sagittal balance and horizontal angle of view, so it can effectively avoid excessive correction and insufficient correction of the deformity and obtain good effectiveness in treating ASK.
Therapeutic drug monitoring (TDM) has been more widely used in small molecule agents, such as immuno-suppressants, antiepileptic drugs and antibiotics, with less attention in the field of therapeutic biological agents. Monoclonal drugs represented by tumor necrosis factor alpha (TNF-α) inhibitors have shown a good relationship between exposure and efficacy in clinical studies. There are corresponding guidelines and consensus for the recommendations of TDM based on current research evidence. Therefore, this paper introduced the current evidence, strategies and considerations for TDM in the optimal treatment of adalimumab from the perspective of adalimumab TDM to provide references for the clinical practice of adalimumab TDM.
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.
Objective To assess the efficacy and safety of Etanercept for Ankylosing spondylitis. Methods We searched The Cochrane Library (Issue 4. 2008), MEDLINE (1966 to September 2008), EMBASE (1974 to September 2008), CBM (1978 to 2008), CNKI (1994 to 2008), VIP (1989 to 2008), and Wanfang (1999 to 2008). The quality of included studies was critically evaluated. Data analyses were performed with The Cochrane Collaboration’s RevMan 5.0 software. Results Seven randomized controlled trials with total of 949 patients met the included criteria. The metaanalysis showed the effective rate of ASAS 20 or ASAS 50 receiving Etanercept was significantly higher than in patients receiving placebo, while no significant differences were noted between the Etanercept and placebo group in other indices. There was no statistical significance among different dosages. Patient Injection-site reaction rate for Etanercept was higher than that for placebo. No significant differences were observed in other adverse effects. Conclusions Etanercept is safe and effective for patients with Ankylosing spondylitis, however, some trials included in the review were of poor quality, so we needed the multi-center, large-scale randomized controlled trials of higher quality and the same course of treatment to confirm this.
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.
ObjectiveTo evaluate the effectiveness of spinal wedged osteotomy and total hip arthroplasty (THA) for treatment of kyphosis and severe hip flexion contracture caused by ankylosing spondylitis (AS). MethodsBetween December 2008 and November 2011,25 patients (37 hips) with kyphosis and severe hip flexion contracture caused by AS were treated.There were 22 males and 3 females,aged 29-38 years (mean,35.6 years).The disease duration was 8-16 years (mean,13.2 years).Of them,18 cases had complete limitation of hip motion,and 16 cases had severe spine deformity (Cobb's angel ≥60°).All 25 cases underwent spinal wedged osteotomy at first,and then received THA after 8 weeks.The effectiveness was evaluated by Harris hip score,range of motion (ROM) of the hip,visual analogue scale (VAS) score,Cobb's angle,and information and data exchange system (IDES) criteria for aseptic loosening,respectively. ResultsThe patients were followed up 12-14 months (mean,13 months).Spondylolisthesis (Ⅱ degree) occurred in 1 case spinal after wedged osteotomy,and was corrected after second operation.No vascular injury or spinal cord injury was observed.Bony fusion was obtained at osteotomy ends at 6 months after operation.The Cobb's angle was significantly corrected from (83.5±10.4)° preoperatively to (25.4±5.5)° (t=24.63,P=0.00) 12 months postoperatively.One case had traction injury of the femoral nerve after THA,and the muscle function recovered at 9 months after operation.According to IDES criteria,up-displacement of cup (<5 mm) was observed in 1 patient,who had no obvious clinical symptoms; periacetabular osteolysis occurred in 1 patient,with no displacement of cup.No obvious radiolucent was seen in 37 hips.The Harris hip score was significantly improved from (26.87±4.23) preoperatively to (85.92±6.04) (t=28.72,P=0.00) 3 months postoperatively; the VAS score was significantly decreased from (6.71±1.14) preoperatively to (2.31±0.82) (t=42.26,P=0.00) 3 months postoperatively; and the flexion-extension ROM of the hip was significantly improved to 60-100° (mean,72.0°) at post-operation,and the abduction ROM of the hip was improved to 20-40° (mean,28.7°). ConclusionSpinal wedged osteotomy combined with THA is an efficient treatment for kyphosis and severe hip flexion contracture caused by AS.
Objective To investigate the effect of the morphological changes in the proximal femur on the prothesis selection in the total hip arthroplasty in the patients with ankylosing spondylitis. Methods The experimental group was composed of 13 patients (16 hips) with ankylosing spondylitis, which was treated with the total hip arthroplasty, and the control group was composed of 16 patients（19 hips）with non-ankylosing spondylitis，which was also treated with the total hip arthroplasty. In the two groups, the measurements of Singh index，canal flare index，morphological index of the cortex and cortical index were performed in the two groups. Results The results of the statistical analysis on Singh index，canal flare index, morphological index of the cortex and cortical index in the experimental group were 3.81±0.54, 2.63±0.41, 2.02±0.38 and 1.69±0.69, respectively, but 4.63±0.62, 3.03±0.27, 2.76±0.28 and 2.12±0.24, respectively in the control group. Therewas a significant difference in Singh index, canal flare index, and morphological index of the cortex between the two groups (Plt;0.05)，while there was no statistical difference in cortical index between the two groups (P＞0.05). The patientswith ankylosing spondylitis had more serious osteoporosis in their proximal femur. Conclusion Cemented femoral prosthesis should be used in the total hip replacement in patients with ankylosing spondylitis, and the revision total hip arthroplasty should be performed on patients with more serious osteoporosis.
Objective To evaluate the efficacy and toxicity of methotrexate (MTX) in the treatment of ankylosing spondylitis (AS). Methods Randomized controlled trials (RCTs) were identified from CENTRAL (The Cochrane Library Issue 4, 2005); MEDLINE (1966 to November 2005); EMBASE (1980 to November 2005); CINAHL (1982 to November 2005). The quality of included trials was evaluated. Data were extracted by two reviewers independently using a specially designed extraction form. The Cochrane Collaboration’s RevMan 4.2 software was used for data analysis. Results Three trials involving 116 patients were included. One 12-month trial compared naproxen plus MTX with naproxen alone. Two 24-week trials compared different doses of MTX with placebo. No statistically significant differences were found for the primary outcome measures of physical function, pain, spinal mobility, peripheral joints/entheses pain, swelling and tenderness, changes in spine radiographs and patient and physician global assessment. The response rate in one trial showed statistically significant benefits of 36% in the MTX group compared with the placebo group (RR 3.18, 95% CI 1.03 to 9.79). This response rate was a composite index including assessment of morning stiffness, physical well-being, Bath ankylosing spondylitis disease activity index (BASDAI), Bath ankylosing spondylitis functional index (BASFI), health assessment questionnaire for spondyloarthropathies (HAQ-S), and physician and patient global assessment. However, no single outcome showed a statistically significant difference between the MTX and placebo groups when endpoint results were compared. Therefore, this benefit of MTX was questionable. No serious side effects were reported in these studies. Conclusions There is no enough evidence to show any benefit of MTX in the treatment of AS. High quality randomized controlled trials of longer duration and with larger sample size are needed to clarify the effect of MTX on AS.
