Objective To investigate the correlation between cervical Modic change (MC) and blood lipid and glucose levels. Methods Patients hospitalized with neck and shoulder pain in the Affiliated Hospital of North Sichuan Medical College between January 2015 and January 2021 were selected and divided into MC group and non-MC group according to whether the signal changes of cervical vertebral endplate occurred on MRI. The general data (age, gender, smoking history, drinking history), blood lipid indicators (high-density lipoprotein, low-density lipoprotein, lipoprotein a, total cholesterol, triglyceride) and blood glucose indicators (glycosylated hemoglobin, fasting blood glucose) were compared between the two groups. Multivariate logistic regression analysis was used to explore the correlation between MC and various indicators. Results A total of 160 patients were included, including 48 patients in MC group and 112 patients in non-MC group. The age [(61.46±12.10) vs. (56.22±10.65) years], total cholesterol [(5.06±1.17) vs. (4.44±1.31) mmol/L], triglyceride [(1.61±0.64) vs. (1.38±0.58) mmol/L], glycosylated hemoglobin (6.78%±1.27% vs. 5.79%±0.85%), and fasting blood glucose [(7.84±1.51) vs. (6.93±1.47) mmol/L] of the patients in MC group were significantly higher than those in non-MC group (P<0.05). There was no significant difference in gender, smoking ratio, drinking ratio, high-density lipoprotein, low-density lipoprotein or lipoprotein a between the two groups (P>0.05). Logistic regression analysisshowed that age [odds ratio (OR)=1.064, 95% confidence interval (CI) (1.022, 1.109), P=0.003], total cholesterol [OR=1.788, 95%CI (1.187, 2.694), P=0.005], triglyceride [OR=2.624, 95%CI (1.257, 5.479), P=0.010] and glycosylated hemoglobin [OR=4.942, 95%CI (2.446, 9.987), P<0.001] were risk factors of cervical MC. Conclusions Age, total cholesterol, triglyceride and glycosylated hemoglobin are risk factors of cervical MC. Elderly patients with hyperlipidemia and hyperglycemia should be alert to the occurrence of cervical MC. Controlling the levels of blood lipid and glucose may reduce the risk of cervical MC.
目的 比较股骨近端抗旋髓内钉（PFNA）与动力髋螺钉（DHS）两种方法内固定治疗高龄股骨粗隆间骨折的疗效。 方法 2007年1月－2011年1月分别采用PFNA、DHS治疗高龄股骨间粗隆骨折（EvansⅠ～Ⅳ型）共68例，其中PFNA组36例，平均年龄81.5岁；DHS组32例，平均年龄82.3岁。两组患者在年龄、性别、骨折分型、合并症以及受伤至手术时间方面比较差异均无统计学意义（P＞0.05），有可比性。 结果 术后68例患者均获随访，随访时间6～26个月。与DHS组比较，PFNA组手术时间短、术中出血少，差异有统计学意义（P＜0.05）；PFNA组骨性愈合时间短，但两组差异无统计学意义（P＞0.05）。术后DHS组出现1例髋内翻、1例拉力螺钉切出股骨头颈，PFNA组出现1例主钉退钉，两组术后并发症发生率比较差异有统计学意义（P＜0.01）。术后1年PFNA组髋关节Harris评分显著高于DHS组，差异有统计学意义（P＜0.01）。 结论 PFNA与DHS两种固定方法的骨性愈合时间短、术后并发症少、髋关节功能恢复好，是治疗股骨粗隆间骨折的良好方式，尤其是PFNA能减少手术时间和术中出血量，手术创伤小，对高龄且不能耐受较大手术者可作为一种首选术式。
Objective To investigate the clinical efficacy of selective tarsometatarsal arthrodesis for old Lisfranc injury without significant post-traumatic osteoarthritis (PTOA). Methods The clinical data of patients with old Lisfranc injury without significant PTOA who were treated by selective tarsometatarsal arthrodesis at Chengdu Pidu District People’s Hospital between June 2013 and June 2021 were analyzed retrospectively. The improvement of patients’ Visual Analogue Scale (VAS) score, American Orthopedic Foot Ankle Society (AOFAS) midfoot score and Short Form 12 (SF-12) score before surgery and at the final follow-up were compared. Results Seventeen oldLisfranc injury patients (17 feet) without significant PTOA were finally recorded, including 12 males and 5 females. All patients completed the surgery successfully, and the surgical incisions healed smoothly after surgery without complications such as poor incision healing, soft tissue ischemic necrosis, and deep and superficial infections. All patients were followed up for an average of 22.6 months (12 to 36 months). Three months after surgery, follow-up X-ray films showed bony healing of the fused ends in all patients, and the patient satisfaction was 94.1%. Compared with the preoperative scores, VAS score (6.0±0.3 vs. 0.8±0.2), AOFAS score (50.5±1.5 vs. 86.5±0.9), SF-12 physiological score (21.9±0.6 vs. 46.1±0.5) and SF-12 psychological score (31.1±0.8 vs. 47.3±0.7) at the last follow-up improved (P<0.05). Conclusion Selective tarsometatarsal arthrodesis for the old Lisfranc injuries without significant PTOA can restore the midfoot force lines and stability, avoid stiffness after full feet fusion, preserve midfoot function, and improve patient satisfaction.
