RESUMEN
Objective:To evaluate the effects of percutaneous kyphoplasty(PKP)and percutaneous vertebroplasty(PVP)operation in elderly patients with osteoporotic vertebral compression fracture(OVCF).Methods:From June 2019 to June 2020, a total of 58 patients with OVCF aged over 60 and under 80 years who had a loss of more than one-third of the anterior margin height of vertebral and agreed to participate in the study were randomly divided into PKP group and PVP group.The visual analogue pain scale(VAS)score, SF-36 quality of life score, anterior height of fractured vertebral body, leakage of bone cement, refracture and cost of high-value consumables were observed at the time point before operation, 1 day, 1 month, 3 month, 6 month, 12 month after operation.Results:VAS scores in PKP and PVP groups were decreased after operation as compared with preoperation( F=115.380, 175.010, both P<0.001). VAS score was lower in the PKP group than in the PVP group at 6 months after operation with statistically significant difference( t=2.219, P=0.031), and no statistically significant difference at other time points between the two groups(all P>0.05). In the PKP and PVP groups, the height of the anterior edge of the vertebral body recovered significantly on the first day after operation, and there was a significant difference in the height compared with that before operation( F=43.020, 51.010, both P<0.001). The SF-36 scores at the latter time point in PKP and PVP groups were increased as compared with the previous time point.The increment of the SF-36 scores was statistically significant at 1 month after operation than pre-operation, and also at 3 months after operation than at 1 month after operation.The leakage rate of bone cement was 37.0%(10/27)in PKP group and 25.0%(7/28)in PVP group, with no significant difference between the two groups( χ2=0.930, P=0.391). The refracture rate was 3.7%(1/27)in PKP group and 7.1%(2/28)in PVP group, with no significant difference between the two groups( χ2=0.000, P=1.000). The cost of high-value consumables for single segment fracture was 46 490 yuan in PKP group, and 36 700 yuan in PVP group.The cost of PKP group was higher than that of PVP group. Conclusions:PKP and PVP operation in the treatment of osteoporotic vertebral compression fractures have good effects in aspect of analgesia, restoring vertebral height and improving patients' quality of life.The analgesic effect is slightly better in PKP group than in PVP group.PVP group has more advantages in health economics.
RESUMEN
Objective:To analyze the epidemiological characteristics of geriatric hip fractures.Methods:This study retrospectively analyzed the clinical characteristics of 2 054 elderly patients with hip fracture aged 60 years and over who were admitted to Beijing Hospital from January 2011 to December 2020.The epidemiological characteristics of geriatric hip fractures were analyzed from the aspects of age, gender, fracture type, length of stay, surgical method and surgical complications.Results:The total number of hip fractures patients admitted from 2011 to 2020 showed a general upward trend in quantity.Among them, there were 1 177 femoral neck fractures(57.3%, 1 177/2 054), and 877 intertrochanteric femoral fractures(42.7%, 877/2 054)with statistical differences in the distribution of fracture types between patients at different ages( χ2=61.727, P<0.001). A total of 1 839 patients chose surgical treatment, accounting for 89.5% of the total number of patients.Artificial femoral head arthroplasty was the most common operation mode for patients with femoral neck fractures(783 cases, 75.4%).534 patients with intertrochanteric femoral fractures(66.8%)were treated with closed reduction and femoral intramedullary nailing.There was a statistically significant difference in operation modes among different fracture types( χ2=1 480.800, P<0.001). The length of hospital stay in patients with femoral neck fracture was(14.2±8.3)days, which was significantly longer than in patients with femoral neck fracture(13.2±10.9)days( t=2.417, P=0.016). There was no significant difference in the time from admission to operation between the two groups[(5.7±3.5)days vs.(5.4±3.3)days]( t=1.954, P=0.051). Among all the comorbidities of hip fracture patients, the top 5 diseases were cardiovascular system diseases(2 001 cases, 97.4%), nervous system diseases(1 105 cases, 53.8%), endocrine system diseases(814 cases, 39.6%), skeletal and muscular system diseases(623 cases, 30.3%), digestive system diseases(472 cases, 23.0%).1 485 patients(72.3%)had 3 or more comorbidities. Conclusions:Hip fractures in the elderly have some epidemiological distribution characteristics in terms of age, gender, length of hospitalization, injury mechanism and comorbidities, which is conducive to further improve the prevention and treatment strategies for hip fractures and promote the rational allocation of medical resources.
