  • 노인 연령층에서 비교적 흔히 발생하는 골절로는 척추압박골절과 고관절 및 손목의 골절이다. 65세이상 여성의 33~50%에서 1곳 이상의 척추압박골절이 발생하고 80세 이상 노인의 약 17%에서 고관절 골절이 발생한다. 특히 여성 노인들은 골절 발생 후 3개월 이내 20%에서 사망하고 생존자의 50%는 영구히 보호시설에서 지내게 된다는 점에서 큰 의미를 지니고 있다고 하겠다.

  • Purpose: The purpose of this study was to evaluate the usefulness of single photon emission computed tomography (SPECT) of bone using Tc-99m MDP in the diagnosis of osteoporotic vertebral fractures. Materials and Methods: Thirty two patients with osteoporotic vertebral fracture were included in this study (mean age: $67{\pm}8$, male: 5, female: 27). Seventy nine vertebral fractures were detected (38 thoracic/thoracolumbar lesions and 41 lumbar lesions), which were classified by type of deformity (wedge, biconcave or compression). The patterns and locations of increased uptakes were examined and analyzed. Results: Forty seven wedge fractures, 20 biconcave fractures and 12 compression fractures were found. Diffuse and asymmetric uptakes were common in fractured bodies. More than one uptake were examined in 69 posterior elements of fractured vertebrae (87.3%) including 40 of 47 wedge fractures (85.1%), 17 of 20 biconcave fractures (85.0%) and 12 of 12 compression fractures (100%). Wedge fractures were predominant fracture in thoracic/thoracolumbar spine whereas incidence of biconcave or compression type war similar to that of wedge fracture in lumbar spine (p=0.04). Spinous process uptake was more frequently seen in lumbar lesions than thoracic/thoracolumbar lesions (p=0.009). Facet joint uptake in biconcave fracture was more common in lumbar spine (92.3%) than thoracic/thoracolumbar spine (57.1%). Spinous process uptake in biconcave fracture was also more frequently detected in lumbar spine (p=0.043). Conclusion: Bone SPECT was useful in the evaluation of osteoporotic vertebral fracture, especially posterior elements of vertebrae.

  • Purpose: To evaluate the characteristics and the risk factors of early onset subsequent vertebral compression fractures after percutaneous vertebroplasty. Materials and Methods: A total of 44 patients, who had a new subsequent vertebral fracture after percutaneous vertebroplasty for an osteoporotic vertebral compression fracture between January 2013 and December 2015, were recruited. The patients were divided into two groups according to the onset period of subsequent fracture. The number of patients who had a fracture within 3 months following vertebroplasty were 22 cases (Group A); after 3 months were 22 cases (Group B). Variables, including age, sex, bone mineral density (BMD), body mass index (BMI), preexisting vertebral compression fracture, location of the initial fracture, intradiscal cement leakage, injected cement volume, restoration of vertebral body height, and correction of kyphosis, in the two groups were analyzed and compared retrospectively. Results: The age, sex, BMD, BMI, preexisting vertebral compression fracture, location of the initial fracture, intradiscal cement leakage, and correction of kyphosis were similar in the two groups. Both a greater volume of bone cement injected and a greater degree of vertebral height restoration contributed significantly to the risk of fracture within 3 months. Conclusion: The cement volume and degree of height restoration are risk factors for early onset fracture at the adjacent vertebrae after percutaneous vertebroplasty and close attention is needed during the follow-up period.

  • We evaluated the effectiveness of Tc-99m labeled antigranulocyte antibody immunoscintigraphy in differentiating the causes of vertebral compression fracture. This study involved 16 patients with vertebral compression fracture; 8 were due to trauma or osteoporosis, 3 were due to metastasis and 5 were due to tuberculous spondylitis. We retrospectively analyzed the location and the extent of decreased tracer uptake in tomographic images of Tc-99m labeled antigranulocyte antibody immunoscintigraphy. Eight patients had a 16 vertebral compression fractures due to trauma or osteoporosis, three patients had 3 vertebral compression fractures due to metastasis and 5 patients had 6 vertebral compression fractures due to tuberculous spondylitis. Sixteen vertebral compression fractures by trauma or osteoporosis showed a normal tracer uptake in pedicle, laminar and spinous process, but there was noted with 6 decreased uptake, 8 absence of tracer uptake and 2 normal tracer uptake in the vertebral body. Two vertebral compression fractures by metastasis showed the absence of uptake in vertebral body, pedicle, laminar and spinous process, and one showed an absence of vertebral body and spinous process. Six vertebral compression fractures by tuberculous spondylitis showed the absence of uptake in six compression fractures, the absence of pedicle in five compression fractures. We concluded Tc-99m labeled antigranulocyte antibody immunoscintigraphy may be helpful to differentiate the causes of vertebral compression fractures.

  • To examine among patients with vertebral compression fracture the extent to which signal-to-noise ratio (SNR) and Apparent Diffusion Coefficient (ADC) values at the lumbar vertebral compression fracture site vary on diffusion-weighted MR images according to varying b values on the 1.5T MR device. Diffusion-weighted MR images of 30 patients with compression fracture due to chronic osteoporosis who underwent vertebral MRI from Jan. 2008 to Nov. 2009 were respectively obtained using a 1.5-T MR scanner with the b values increased from 400, 600, 800, 1,000 to $1,200\;s/mm^2$. For diffusion-weighted MR images with different b values, the signal-to-noise ratio (SNR) was assessed at three sites: the site of compression fracture of the lumbar vertebral body at L1 to L5, and both the upper and lower discs of the said fracture site, while for ADC map images with different b values, the SNR and ADC were respectively assessed at those three sites. As a quantitative analysis, diffusion-weighted MR images and ADC map images with b value of $400\;s/mm^2$ (the base b values) were respectively compared with the corresponding images with each different b value. As far as qualitative analysis is concerned, for both diffusion-weighted MR and ADC map images with b value of $400\;s/mm^2$, the extent to which signal intensity values obtained at the site of compression fracture of the lumbar vertebral body at L1 to L5 vary according to the increasing b values were examined. The quantitative analysis found that for both diffusion-weighted MR and ADC map images, as the b values increased, the SNR were relatively lowered at all the three sites, compared to the base b value. Also, it was found that as the b values increased, ADC valueswere relatively lowered at all the three sites on ADC map images. On the other hand, the qualitative analysis found that as the b values increased to more than $400\;s/mm^2$, the signal intensity gradually decreased at all the sites, while at the levels of more than $1,000\;s/mm^2$, severe image noises appeared at all of the three sites. In addition, higher signal intensity was found at the site of compression fracture of the lumbar vertebral body than at the discs. Findings showed that with the b value being increased, both the signal-to-noise ratio (SNR) and Apparent Diffusion Coefficient (ADC) values gradually decreased at all the sites of the lumbar vertebral compression fracture and both the upper and lower discs of the fracture site, suggesting that there is a possibility of a wider range of applications to assessment of various vertebral pathologies by utilizing multi b values in the diffusion-weighted MRI examination.

  • Percutaneous balloon kyphoplasty is an option for pain relief in pathological vertebral compression fractures. Complications related to cement leakage through cortical defects have been reported. On the other hand, dural compression due to retropulsion of the tumor mass is rarely reported. The authors report a case of a 65-year female patient who had cauda equina syndrome after a percutaneous balloon kyphoplasty in a pathological vertebral fracture, even though epidural compression were not found prior to surgery. Magnetic resonance imaging revealed retropulsion of the tumor mass into the spinal canal through the disrupted posterior vertebral cortex.

  • By analyzing the severally clinical characteristics such as the prevalence by gender and age, and the developmental region, and the developmental factor in terms of vertebral compression fracture, which was diagnosed by MRI(Magnetic Resonance Imaging), the following conclusions were obtained. 1. The general characteristics in 183 research subjects, were 70 men (38.0%) and 113 women (62.0%), and aged from the minimum 16 years old to the maximum 84 years old. 2. Among 183 persons with abnormal findings in vertebral compression fracture, the single compression fracture was included 111 persons (60.7%) with 38 men (34.0%) and 73 women (66.0%), and women in their 60s were largest with 32 persons. 3. As the multiple compression fracture was included 72 persons (39.3%) among 183 research subjects, and as the incidence had 182 cases, this is what classified the case in which one person with abnormal findings has the compression fracture at the levels with more than one, and there were 70 cases (38.0%) in men and 112 cases (62.0%) in women, and it is being indicated the large frequency in women in their 60s and in their 70s. 4. The developmental regions in the single compression fracture and the multiple compression fracture, were generated about 70% of the whole at $T11{\sim}L2$. 5. In terms of the prevalence by cause for compression fracture in 183 whole subjects, it was largest with 41.4% in the fracture caused by trauma in case of men, and with 70.0% in what was caused by the osteoporosis in case of women, and as for a case that combined men and women, it was largest with 56.8% in the vertebral compression fracture caused by osteoporosis.

  • Since surgical treatment of the spine should overcome neurological compromises, the operative procedures need to be carefully planned and carried out with high degree of precision. Percutaneous vertebroplasty is a surgical procedure that was introduced for the treatment of compression fracture of the vertebrae. This procedure includes puncturing vertebrae and filling with polymethylmethacrylate (PMMA). Recent studies have shown that the procedure could provide structural reinforcement for the osteoporotic vertebrae while being minimally invasive and safe with immediate relief of pain. However, failures of treatment due to excessive PMMA volume injection have been reported as one of complications in vertebroplasty. It is believed that the control of PMMA volume is one of the most critical factors that can reduce the incidence of complications. Therefore, clinical success of vertebroplasty can be dependent on the volume of PMMA injection for a given patient. In this study, the optimal volume of PMMA injection for vertebroplasty was predicted based on the image analysis of a given patient.

  • This study investigates the biomechanical efficacies of vertebroplasty which is used to treat vertebral body fracture with bone cement augmentation for osteoporotic patients using image and finite element analysis. Simulated models were divided into two groups: (a) a vertebral body, (b) a functional spinal unit(FSU). For a vertebral body model, the maximum axial displacement was investigated under axial compression to evaluate the effect of structural integrity. The stiffness of each FE model simulated was normalized by the stiffness of intact model. In the case of FSU model, 3 types of compression fractures were formulated to assess the influence on spinal curvature changes. The FSU models were loaded under compressive pressure to calculate the change of spinal curvature. The results according to the various factors suggest that vertebroplasty has the biomechanical efficacy of the increment of structural reinforcement in a patient who has relatively high level of BMD and a patient with the amount of 15%, PMMA injection of the cancellous bone volume. The spinal curvatures after compression fracture simulation vary from 9$^{\circ}$ to 17$^{\circ}$ of kyphosis compared to that the spinal curvature of normal model was -2.8$^{\circ}$ of lordosis. These spinal curvature changes cause the severe spinal deformity under the same loading. As the degree of compressive fracture increases the spinal deformity also increases. The results indicate that vertebroplasty has the increasing effect of the structural integrity regardless of the amount of PMMA or BMD and the restoration of decreased vertebral body height may be an important factor when the compressive fracture caused the significant height loss of vertebral body.

  • Spinal epidural hematoma (SEH) can occur naturally or traumatically and is most common in patients with an underlying disease of the vascular structure or coagulation disorder. Most SEHs occur naturally for no apparent reason, and epidural hematoma caused by trauma is less common, comprising 1.0%-1.7% of total spinal injuries. Few reports of SEH induced cauda equine syndrome resulting from low-energy injury caused by osteoporotic vertebral compression fractures are available. The authors experienced a case of delayed SEH after hemorrhage due to a low-energy injury in an elderly patient. No cases in Korea have been reported; therefore, this case is reported with a review of the relevant literature.
