【Abstract】 Objective To observe the clinical symptoms, laboratory results, images of vertebral compression fractures to analyze the diagnosis procedures to reduce the misdiagnosis rate. Methods All 368 cases of vertebral compression fractures were reviewed from 2008. 2 to 2017. 7. There were 116 males, 262 females. All patients were divided into 3 groups: Group A（ osteoporosis, n = 215）; Group B（ metastases, n = 119）; Group C（ multiple myeloma, n = 44）. Observation index: sex, age, BMI, nerve signs, VAS. Laboratory examination: Hemoglobin, ESR, A/G, tumor markers. Imaging features: morphological characteristics, vertebral signals, pedicle and appendage, linear high signals in the vertebral body, soft tissue mass, vertebral edge. An independent sample t test or Mann-Whitney U test was used to compare the results among 3 groups. Chi square test was used to compare the counting data. Results Group A: the average age was older( t_AB =-3.581, P = 0.023; t_AC =-3.979, P = 0.011); more women( χ_AB² = 38.369, P = 0.000; χ_AC² = 69.295, P = 0.000); lower BMI( Z_AB =-4.011, P = 0.015; Z_AC =-7.454, P = 0.000); lower VAS score( Z_AB =-2.375, P = 0.045; Z_AC =-2.463, P = 0.047). Group B: Neuropathic symptoms often occurred( χ_AB² = 120.297, P = 0.000; χ_BC² = 35.108, P = 0.000); more positive tumor markers( χ_AB² = 122.738, P = 0.000; χ_BC² = 30.032, P = 0.000); Group C: more positive ESR A/G and HGB rates( χ_AC² = 124.213, P = 0.000; χ_BC² = 81.941, P = 0.000). Vertebrae wedge often occurred in Group A( χ_AB² = 87.765, P = 0.000; χ_AC² = 58.607, P = 0.000). Vertebrae biconcave often occurred in Group A and C( χ_AB² = 12.309, P = 0.000; χ_BC² = 14.677, P = 0.000). Vertebrae plana often occurred in Group B and C( χ_AB² = 177.179, P = 0.000; χ_AC² = 80.349, P = 0.000). The MRI signal short T₁ and long T₂ often occurred in Group A and C( χ_AB² = 62.127, P = 0.000; χ_BC² = 25.329, P = 0.000). Pedicle involvement often occurred in Group B( χ_AB² = 173.577, P = 0.000; χ_BC² = 38.564, P = 0.000). Soft tissue mass often occurred in Group B( χ_AB² = 317.126, P = 0.000; χ_AC² = 233.000, P = 0.000). Linear high signal often occurred in Group A( χ_AB² = 317.126, P = 0.000; χ_AC² = 233.000, P = 0.000). Bulge of posterior vertebral edge often occurred in Group B( χ_AB² = 174.031, P = 0.000; χ_BC² = 58.704, P = 0.000). Conclusions The diagnosis of vertebral compression fractures caused by osteoporosis, spinal metastases and multiple myeloma should be made combining with clinical features, laboratory examination and radiological data. For the patients with unidentified diagnosis, ECT, PET-CT, bone marrow aspiration and lesion biopsy should be further performed to reduce the misdiagnosis rate.更多还原
