Objective To analyze the differences of ADC values in breasts of women of different ages and different menstrual phases, so as to direct the choice of the examination time of MR DWI. MethodsThe breasts of 65 healthy volunteers were scanned with the routine MRI plain scan and DWI in the menstrual, proliferative and secretary phases. DWI was conducted with single shot echo planar imaging technique and b value were 0, 1000 s/mm2. The women were divided into three groups: Group 1(aged 20 to 29 years, 21 cases), Group 2 (aged 30 to 39, 21cases), and Group 3 (aged 40 to 49, 23 cases). The ADC values of all 130 breasts at nipple level in the different phases were measured. The ADC values in the three age groups and in the different menstrual phases were compared using ANOVA. Results The mean ADC values of Group 1 were (2.14±0.14) ×10-3, (2.03±0.18) ×10-3and (2.10±0.19)×10-3mm2/s for left breast, and (2.08±0.17) ×10-3, (2.02±0.16) ×10-3and (2.09±0.17) ×10-3mm2/s for right breast in the menstrual, proliferative and secretary phases. They were slightly higher than Group 3, which were (2.02±0.27) ×10-3, (1.97±0.25) ×10-3and (2.03±0.22)×10-3 mm2/s for left breast and (1.99±0.29) ×10-3, (1.93±0.26) ×10-3and (2.03±0.28)×10-3 mm2/s for right breast. The mean ADC values of Group 2 [left breast: (1.94±0.25) ×10-3, (1.91±0.21) ×10-3and (1.97±0.21)×10-3 mm2/s ; right breast: (1.97±0.26)×10-3, (1.89±0.25)×10-3and (1.96±0.22)×10-3 mm2/s) were the lowest among the three age groups. There were significant differences in different menstrual phases (F= 23.600, P<0.01), but no statistical difference was found among the three age groups or between left breasts and right breasts (F= 1.683, 2.248;P>0.05).Conclusions The mean ADC values of breasts decrease markedly in the proliferative phase.The effects of the menstrual cycle on the breast ADC values should be considered in the evaluation of breast diseases with DWI.

Objective:To characterize tibial plateau fractures using a computed-tomography-based "four-column and nine-segment" classification.Methods:A retrospective analysis was conducted of the 698 adult patients with tibial plateau fracture (704 knees) who had been admitted to Department of Orthopedics, The Affiliated People's Hospital of Jiangsu University from December 2007 to May 2018. They were 377 males and 321 females with an average age of 51.6 years. The left knee was affected in 371 cases (53.2%), the right knee in 321 cases (46.0%) and bilateral knees in 6 cases (0.9%). According to the differentiated morphological characteristics, the tibial plateau and proximal fibula were divided into 4 columns, which were subdivided into 9 segments. Tibial plateau injury index (TPII) was innovatively introduced to represent the extent of injury. Fracture mapping was retrospectively analyzed according to the "four-column and nine-segment" classification based on the CT imaging.Results:The rates of one-column, two-column, three-column and four-column injuries were 30.5% (215/704), 31.5% (222/704), 28.0% (197/704), and 9.9% (70/704), respectively. On average, 2.2 columns ± 1.0 columns and 3.6 segments ± 2.1 segments were affected in each case. The mean TPII was 5.7±3.0. The rates of mild, moderate and severe comminuted fractures were 50.0% (352/704), 37.5% (264/704), and 12.5% (88/704). The columns most frequently affected were the lateral column (572, 81.3%) and the intermedial column (524, 74.4%) while the less frequently involved ones the medial column (219, 31.1%) and the fibular column (218, 31.0%). The sequence of the segments affected was the posterolateral segment (465, 66.1%), the anterolateral segment (453, 64.3%), the posteromedian segment (379, 53.8%) and the tubercle segment (85, 12.1%).Conclusions:The novel "four-column and nine-segment" classification may be a beneficial system for clinical diagnosis, statistical analysis and prognostic judgment of tibial plateau fractures.

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.
