OBJECTIVE: To explore the effectiveness of the combined anteversion angle technique in total hip arthroplasty (THA) for treating ankylosing spondylitis (AS) affecting the hip joint. METHODS: A retrospective analysis was conducted on the clinical data of 73 patients with AS affecting the hip joint who underwent THA between August 2018 and August 2021. According to whether the combined anteversion angle technique was used in THA, the patients were divided into study group (37 cases, combined anteversion angle technique was used in THA) and control group (36 cases, traditional THA). There was no significant difference in baseline data such as gender, age, body mass index, disease duration, preoperative Harris score, range of motion (ROM), acetabular anteversion angle, acetabular abduction angle, femoral anteversion angle, and combined anteversion angle between the two groups ( P>0.05). The operation time, hospital stay, and complications of the two groups were recorded and compared. The Harris score and hip ROM were compared between the two groups before operation, at 1, 3, 6, 12 months after operation, and at last follow-up. The acetabular component anteversion angle, femoral component anteversion angle, acetabular component abduction angle, and component combined anteversion angle were measured postoperatively. RESULTS: The operation time in the study group was significantly shorter than that in the control group ( P<0.05), and there was no significant difference in hospital stay between the two groups ( P>0.05). There was no intraoperative complication such as acetabular and proximal femoral fractures, neurovascular injuries in both groups, and the incisions healed by first intention. All patients were followed up 2-3 years, with an average of 2.4 years; there was no significant difference in the follow-up time between the two groups ( P>0.05). During the follow-up period, there was no complication such as hip dislocation, wound infection, delayed wound healing, deep venous thrombosis, and hip dislocation in both groups. The hip Harris score and ROM of the two groups gradually increased with time after operation, and the differences were significant when compared with those before operation ( P<0.05); the above two indicators of the study group were significantly better than those of the control group at each time point after operation ( P<0.05). Extensive bone ingrowth on the surface of the components could be observed in the anteroposterior X-ray films of the hip joint of the two groups at 12 months after operation, and the acetabular components was stable without femoral stem subsidence, osteolysis around the components, and heterotopic ossification. At last follow-up, the acetabular component anteversion angle, femoral component anteversion angle, and component combined anteversion angle in the study group were significantly superior to those in the control group ( P<0.05), except that there was no significant difference in the acetabular component abduction angle between the two groups ( P>0.05). CONCLUSION For patients with AS affecting the hip joint, the use of the combined anteversion angle technique during THA effectively promotes the recovery of hip joint function and enhances the postoperative quality of life of patients when compared to traditional THA.

Parturients with both ankylosing spondylitis (AS) and SARS-CoV-2 Infection (COVID-19) present unique challenges to anesthesiologists. Neuraxial analgesia for labor remains the gold standard in obstetric patients. However, in patients with AS, this approach may be deemed difficult to impossible. Administration of systemic opioids for labor analgesia can be an option, bearing in mind the potential respiratory depressant effect to both the mother and the fetus, especially in the setting of concomitant COVID-19. This paper reports the successful management of such a patient using patient-controlled analgesia (PCA) with intravenous remifentanil.

This study aimed to analyze the impact of traditional Chinese medicine(TCM) on the risk of re-admission for ankylosing spondylitis(AS) patients with dampness-heat syndrome. In this study, a telephone follow-up was conducted on 1 295 AS inpatients, and after screening and exclusions, 1 044 successfully followed-up patients were included. A retrospective cohort study was conducted using propensity score matching(PSM), and a Cox proportional risk model was employed to assess the effect of various factors on the risk of re-admission for AS patients with dampness-heat syndrome. Kaplan-Meier survival curves were used to analyze the effect of TCM intervention time on re-admission. The incidence rate of dampness-heat syndrome in AS patients was found to be 51.3% in this study. After 1∶1 PSM, 385 AS patients with dampness-heat syndrome and 385 AS patients without dampness-heat syndrome were included for analysis. The results indicated that the re-admission rate was higher for patients with dampness-heat syndrome compared with those without dampness-heat syndrome(P<0.05). AS patients with dampness-heat syndrome in the TCM group had a lower admission rate than those in the non-TCM group(P=0.01). The cox proportional risk model demonstrated that TCM was an independent protective factor, as it reduced the risk of re-admission by 35%(HR=0.35, 95%CI[0.26, 0.95], P<0.05). Moreover, the subgroup with high exposure(time to use Chinese medicine >12 months) had a significantly lower risk of re-admission than that with low TCM exposure(time to use Chinese medicine ≤12 months). The re-admission rate for AS patients with dampness-heat syndrome was higher than that without dampness-heat syndrome, and TCM was identified as a protective factor in reducing the risk of re-admission. Furthermore, a longer duration of TCM intervention was associated with a lower risk of re-admission.

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 T ₁₁ in 2 cases, T ₁₂ in 2 cases, L ₁ in 6 cases, and L ₂ 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.

Objective: To summarize the clinical, radiological characteristics, and prognosis of infectious sacroiliitis in children. Methods: A case-control study was conducted, including 12 cases of infectious sacroiliitis diagnosed in the Rheumatology and Immunology Department of the Children's Hospital affiliated with the Capital Institute of Pediatrics from June 2018 to June 2023. These cases comprised the case group. Concurrently, 28 cases of pediatric idiopathic arthritis involving the sacroiliac joint in the same department served as the control group. Basic patient information, clinical features, laboratory parameters, and clinical treatment outcomes for both groups were collected and analyzed. Independent sample t-tests and chi-squared tests were used for inter-group comparisons. Results: Among the 12 cases in the case group, there were 5 males and 7 females, with a disease duration of 0.8 (0.5, 1.2) months. Nine patients presented with fever, and 1 patient had limping gait. Human leukocyte antigen (HLA)-B27 positivity was observed in 1 case, and there was no family history of ankylosing spondylitis. In the control group of 28 cases, there were 19 males and 9 females, with a disease duration of 7.0 (3.0, 17.0) months. One patient (4%) had fever, and 14 cases (50%) exhibited limping gait. HLA-B27 positivity was found in 18 cases (64%), and 18 cases (64%) had a family history of ankylosing spondylitis. The case group had higher white blood cell count (WBC), neutrophil ratio, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, as well as a higher proportion of unilateral involvement on magnetic resonance imaging and bone destruction on CT compared to the control group ((11.1±6.2)×10⁹ vs. (7.3±2.3)×10⁹/L, 0.64±0.10 vs. 0.55±0.12, 72 (34, 86) vs. 18 (5, 41) mm/1 h, 24.6 (10.1, 67.3) mg/L vs. 3.6 (0.8, 15.0) mg/L, 11/12 vs. 36% (10/28), 9/12 vs. 11% (3/28), t=2.90, 3.07, Z=-2.94, -3.28, χ²=10.55, 16.53, all P<0.05). Conclusions: Pediatric infectious sacroiliitis often presents as unilateral involvement with a short disease history. Elevated WBC, CRP, and ESR, as well as a high rate of bone destruction, are also common characteristics.

OBJECTIVE: To explore the correlation of polymorphisms of AF4/FMR2 family genes and IL-10 gene with genetic susceptibility to ankylosing spondylitis (AS) and identify the high-risk factors of AS. METHODS: This case-control study was conducted among 207 AS patients and 321 healthy individuals. The tag single nucleotide polymorphisms (SNPs) rs340630, rs241084, rs10865035, rs1698105, and rs1800896 of the AF4/FMR2 family gene and IL-10 gene of the AS patients were genotyped, and the distribution frequencies of the genotypes and alleles were analyzed to explore the relationship between different genetic models and AS and the gene-gene and gene-environment interactions. RESULTS: Gender ratio, smoking history, drinking history, hypertension, erythrocyte sedimentation rate and C-reactive protein differed significantly between the case group and the control group (P < 0.05). The dominant model and recessive model of AFF1 rs340630, the recessive model of AFF3 rs10865035, and the recessive model of IL-10 rs1800896 were significantly different between the two groups (P=0.031, 0.010, 0.031, and 0.019, respectively). Gene-environment interaction analysis suggested that the interaction model incorporating AFF1 rs340630, AFF2 rs241084, AFF3 rs10865035, AFF4 rs1698105, IL-10 rs1800896, smoking history and drinking history was the best model. The genes related with AF4/FMR2 and IL-10 were enriched in the biological processes of AF4 super extension complex, interleukin family signal transduction, cytokine stimulation and apoptosis. The expression levels of AF4/FMR2 and IL-10 were positively correlated with immune infiltration (r > 0). CONCLUSION The SNPs of AF4/FMR2 and IL-10 genes are associated with the susceptibility to AS, and the interactions of AF4/FMR2 and IL-10 genes with the environmental factors contributes causes AS through immune infiltration.

OBJECTIVE: To observe the efficacy of the combined treatment with acupuncture and governor vessel moxibustion on ankylosing spondylitis (AS) at early-middle stage and investigate the effect on bone marrow edema of sacroiliac joint. METHODS: Seventy patients of AS at early-middle stage were randomized into an observation group (35 cases) and a control group (35 cases, 1 case dropped off ). In the control group, the recombinant human tumor necrosis factor receptor-antibody of type Ⅱ fusion protein for injection was injected subcutaneously, 25 mg each time, once on every Monday and Friday, consecutively for 3 weeks. In the observation group, on the base of the intervention as the control group, acupuncture combined with governor vessel moxibustion were provided. Acupuncture was applied to Dazhui (GV 14), Changqiang (GV 1), Zhibian (BL 54), Baihui (GV 20), etc.; the thermal needling technique was adopted at Dazhui (GV 4) and Changqiang (GV 1) for promoting the circulation of the governor vessel, and the ginger-isolated moxibustion on the governor vessel was combined. Such intervention measure was provided once daily. One treatment session contained 7 treatments and 3 sessions were required. Before and after treatment, the scores of Spondyloarthritis Research Consortium of Canada (SPARCC), Bath ankylosing spondylitis disease activity index (BASDAI) and Bath ankylosing spondylitis functional index (BASFI) and Bath ankylosing spondylitis patient global score (BAS-G) were observed in the two groups separately. The efficacy and adverse effects were assessed in the two groups after treatment. RESULTS: The scores of SPARCC, BASDAI, BASFI and BAS-G were all reduced after treatment compared with those before treatment in the two groups (P<0.05), and those in the observation group were lower than the control group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 82.4% (28/34) in the control group (P<0.05). There were 4 cases of gastrointestinal reactions and 1 case of skin rashes in the control group; and 3 cases of local skin redness and pruritus after governor vessel moxibustion, no any drug adverse effect was found in the observation group. CONCLUSION Based on the western medicine treatment, the combined therapy of acupuncture and governor vessel moxibustion may relieve bone marrow edema of sacroiliac joint in patients with AS at early-middle stage, control the progression of disease and improve the daily life activity. This therapy is relatively safe and effective.
