Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.

Objective:To identify the anatomical distribution of and factors related to single-segment osteoporotic vertebral compression fractures (OVCF).Methods:The radiology and clinical data of 944 patients with single-segment OVCF hospitalized in Zhongda Hospital Southeast University between June 2016 and October 2020 were retrospectively analyzed, including 175 males and 769 females, aged 72.1±9.6 years (range, 45-97 years). The anatomical distribution of OVCF was quantified. The demographics, comorbidity profile, spine trauma, back pain duration, vertebral compression degree, and bone mineral density of the OVCF patients in different anatomical segments were summarized and compared.Results:Of the 944 single-segment OVCF, 864 were located in the lower thoracic and lumbar spine that peaked at L 1 (Modal-1 group), and 80 were located in the middle and upper thoracic spine (Modal-2 group) that peaked at T 7, demonstrating an asymmetric bimodal distribution. The difference in the female/male ratio between the two groups was insignificant (χ 2=0.06, P=0.803). Patients in Modal-2 were aged 75.0±9.8 years and on average older than the patients (aged 71.8±9.6 years) in Modal-1 ( t=2.78, P=0.005). The female patients in Modal-2 (aged 75.0±9.6 years) were significantly older than that (aged 71.2±9.3 years) in Modal-1 ( t=3.17, P=0.002). The ratio of back pain duration for <1 week in Modal-2 (43.8%) was lower than that in Modal-1 (60.2%), and the ratio of back pain for 1-weeks (28.8%) was significantly higher than that (15.5%) in Modal-1 (χ 2=11.50, P=0.009). The most frequently reported spine traumas in Modal-2 (50.0%) were heavy lifting injury, lumbar sprain, and strenuous cough, which were significantly different from and less apparent than the fall on ground or crush injury to the spine (64.1%) in Modal-1 (χ 2=60.71, P<0.001). The anterior to posterior height ratio of the fractured vertebrae in Modal-2 was 0.78±0.13, 0.83±0.14, 0.84±0.13, and 0.78±0.18 in the OVCF patients complaining of back pain for <1 week, 1-weeks, 2-weeks, and >4 weeks respectively, showing no significant difference between groups ( F=1.01, P=0.009). In Modal-1, the anterior to posterior height ratio of the fractured vertebrae was lower in the OVCF patients complaining of back pain for 2-weeks (0.80±0.15) and >4 weeks (0.77±0.19) than in those with back pain for <1 week (0.85±0.11) and 1-weeks (0.86±0.14), with sinificant differences ( P<0.05). 32.4% (306/944) of the OVCF patients had one of the following geriatric comorbidities: hypertension, diabetes mellitus, coronary heart disease, cerebral infarction, and chronic obstructive pulmonary disease. The OVCF patients in Model-2 had higher comorbidity of coronary heart disease (21.3%) and cerebral infarction (36.3%) than those in Model-1 (11.6% and 20.3%). Bone mineral density information was available from 371 patients (308 females). In the age groups of <70, 70-, and >80 years, no significant difference was detected in the T-score values of the lumbar spine or hip joint between the OVCF patients in Model-1 and Model-2 ( F=0.13, P=0.880; F=0.62, P=0.538). Conclusion:Single-segment OVCF feature an asymmetric bimodal distribution that is demarcated by the T 10 vertebrae. The distribution pattern is not determined by gender or baseline bone mineral density but highlights the risk of mechanical stress and vertebral fragility within a specific segment. OVCF in the middle and upper thoracic spine is less frequent but common in older patients with higher comorbidity of coronary heart disease and cerebral infarction, which tend to be caused by less apparent spine trauma and maintain vertebral compression but complain of long back pain duration.

Objective:To identify the incidence and risk factors related to lumbodorsal fasciitis in acute osteoporotic vertebral compression fractures (OVCF).Methods:The clinical data of 1182 acute OVCF hospitalized in Zhongda Hospital Southeast University between June 2016 and October 2020 were retrospectively analyzed, including 219 males and 963 females, aged 72.19±9.39 years (range, 45-98 years). The demographics, comorbidity profile, spine trauma, back pain duration, and vertebral fracture number of the OVCF with or without lumbodorsal fasciitis were summarized and compared. The independent risk factors of lumbodorsal fasciitis were identified by binary logistic regression analysis.Results:There were 532 cases of OVCF complicated with lumbodorsal fasciitis among 1,182 patients, and the incidence was 45.01%. The OVCF with fasciitis had higher ratio of males (23.5%, 125/532) than the OVCF without (14.5%, 94/650) fasciitis (χ 2=15.82, P<0.001). The OVCF with fasciitis were aged 74.57±9.21 years and significantly older than the OVCF (aged 70.24±9.60 years) without fasciitis ( t=7.85, P<0.001). The highest proportion of patients with OVCF combined with fasciitis was ≥80 years old (36.1%, 192/532), while most (34.6%, 225/650) of the OVCF without fasciitis were aged 60-70 years (χ 2=56.27, P<0.001). The OVCF with fasciitis had higher ratio of no evident spine trauma (37.0%, 197/532) and multiple vertebral fractures involving ≥3 vertebra (10.5%, 56/532) than the OVCF without fasciitis [26.3% (171/650), 3.2% (21/650); χ 2=17.67, P<0.001; χ 2=40.63, P<0.001]. The ratio of pre-hospital back pain >4 weeks was higher in the OVCF with (20.7%, 110/532) than without (7.4%, 48/650) fasciitis (χ 2=62.46, P<0.001). The OVCF with fasciitis had higher comorbidity of hypertension (52.8%, 281/532), coronary heart disease (14.7%, 78/532), and cerebral infarction (24.8%, 132/532) than the OVCF without fasciitis [42.8% (278/650), 9.9% (64/650), 17.9% (116/650); χ 2=11.85, P<0.001; χ 2=6.42, P=0.011; χ 2=8.56, P=0.003]. The OVCF with fasciitis had higher ratio of two comorbidities (23.7%, 126/532) than the OVCF without fasciitis (16.1%, 105/650) (χ 2=21.15, P<0.001). Binary logistic regression analysis showed significantly higher risk of lumbodorsal fasciitis in males than in females ( OR=1.69, P=0.001), in age group 60-<70、70-<80 and ≥80 years than in <60 years ( OR=2.28, P=0.002; OR=2.64, P<0.001; OR=4.90, P<0.001), in back pain for 2-<4 weeks and >4 weeks than in ≤1 week ( OR=1.70, P=0.005; OR=3.81, P<0.001), and in multiple fractures involving 2 and ≥3 vertebra than in single vertebrae ( OR=1.75, P=0.003; OR=3.36, P<0.001). Conclusion:Up to 45% of acute OVCF have concurrent lumbodorsal fasciitis. Male, aged ≥60 years, pre-hospital back pain ≥2 weeks, and fractures in ≥2 vertebra are independent risk factors of lumbodorsal fasciitis in OVCF.

Objective: This study’s objective is to assess the efficacy and safety of Pulsed Magnetic Therapy System (PMTS) in improving insomnia disorder. Methods: Participants with insomnia disorder were randomly assigned to receive either PMTS or sham treatment for four weeks (n= 153; PMTS: 76, sham: 77). Primary outcomes are the Insomnia Severity Index (ISI) scores at week 0 (baseline), 1, 2, 3, 4 (treatment), and 5 (follow-up). Secondary outcomes are the Pittsburgh Sleep Quality Index at baseline and week 4, and weekly sleep diary-derived values for sleep latency, sleep efficiency, real sleep time, waking after sleep onset, and sleep duration. Results: The ISI scores of the PMTS group and the sham group were 7.13±0.50, 11.07±0.51 at week 4, respectively. There was a significant group×time interaction for ISI (F3.214, 485.271=24.25, p<0.001, ηp 2=0.138). Only the PMTS group experienced continuous improvement throughout the study; in contrast, the sham group only experienced a modest improvement after the first week of therapy. At the end of the treatment and one week after it, the response of the PMTS group were 69.7% (95% confidence interval [CI]: 58.6%–79.0%), 75.0% (95% CI: 64.1%–83.4%), respectively, which were higher than the response of the sham group (p<0.001). For each of the secondary outcomes, similar group×time interactions were discovered. The effects of the treatment persisted for at least a week. Conclusion PMTS is safe and effective in improving insomnia disorders.

Osteoporotic thoracolumbar fracture in the elderly will seriously reduce their quality of life and life expectancy. For osteoporotic thoracolumbar fracture in the elderly, spinal reconstruction is necessary, which should comprehensively consider factors such as the physical condition, fracture type, clinical characteristics and osteoporosis degree. While there lacks relevant clinical norms or guidelines on selection of spinal reconstruction strategies. In order to standardize the concept of spinal reconstruction for osteoporotic thoracolumbar fracture in the elderly, based on the principles of scientificity, practicality and progressiveness, the authors formulated the Clinical guideline for spinal reconstruction of osteoporotic thoracolumbar fracture in elderly patients ( version 2022), in which suggestions based on evidence of evidence-based medicine were put forward upon 10 important issues related to the fracture classification, non-operative treatment strategies and surgical treatment strategies in spinal reconstruction after osteoporosis thoracolumbar fracture in the elderly, hoping to provide a reference for clinical treatment.
