The compressed fracture of spine caused by osteoporosis is one of the most frequent diseases in bone fracture. Recently the vertebroplasty has drawn much attention as a medical treatment for the compressed fracture of spine, which strengthens the vertebral body and corrects deformity, and relieves pain in patients by injecting bone cement. The purpose of this research is to provide the theoretical background for the vertebroplasty by employing scientific methods and thus to find out the improvements of the conventional surgical method. By applying the engineering analysis tools to clinical study, new application fields can also be obtained

Vertebral compression fractures result in vertebral height loss and alter sagittal spinal alignment, which in turn can lead to increased morbidity and mortality. Acute osteoporotic vertebral compression fractures are known to increase mobility and instability of the spine. There are limited published data correlating the degree of dynamic mobility and the efficacy of kyphoplasty on vertebral compression fractures. Here we report a 73-year-old female with a severe acute osteoporotic L2 compression fracture who obtained total vertebral height restoration following kyphoplasty, with resolution of back pain.

Complex cervical spine fractures are a serious complications of maxillofacial trauma and associated with high mortality and neurological morbidity. Strict vigilance in preventing further insult to the cervical spine is a crucial step in managing patients who are at risk for neurologic compromise. We report a rare case of a right transverse process of atlas fracture with right-sided vertebral artery injury that was associated with a comminuted fracture of the body and angle of the mandible, which restricted mouth opening. Airway management was performed by an awake fiber-optic nasotracheal intubation, where neck movement was avoided with a cervical collar. Vertebral artery injuries may have disastrous consequences, such as basilar territory infarction and death, and should be suspected in patients with head and neck trauma. After mandibular plating, the patient was on cervical collar immobilization for 12 weeks and anti-coagulant therapy.

Purpose: A missed fracture is a very common occurrence in the Emergency Department (ED) and can have serious results because of delays in treatment, resulting in long-term disability. It is also one of the most common causes leading to medical legal issues. We analyzed the causes of missed fractures by using a bone scan which is known to be an effective tool for diagnosing bony lesions. Methods: We reviewed the medical records of trauma patients who underwent a bone scan after being discharged the ED from September 2006 to March 2008. Cases of missed fractures were identified by using electronic medical records to review each diagnosis. Definition of missed fracture was read after bone scan by radiologist. We decided that there was no fracture if we read 'trauma-related lesion' or 'cannot rule out fracture' on a bone scan read by a radiologist. Enrolled patients were analyzed by age, sex, time until bone scan and Injury Severity Score (ISS). Patients were divided into two groups, alert mentality and not-alert mentality, so there were split between a diagnosis group and a missed fracture group. ISS was also used in determining the severity of the patient's injury upon discharge from the ED. Results: A total of 532 patients were enrolled in this study. Of those, 487 patients were in the diagnosis group, and 45 patients (8.4%) were discovered to have had a fracture. Of the 45 missed fracture patients, 34 patients (6.4%) had one-site fractures, 8 patients (1.5%) had two-site fractures, and 3 patients (0.6%) had three-site fractures. The most commonly missed fracture was multiple rib fractures (18 patients, 30.5%), followed by lumbosacral (LS) spine fractures (10 patients, 16.9%), thoracic spine fractures (8 patients, 13.6%), and clavicle fractures (6 patients, 10.2%). Mean age was $50.12{\pm}18.54$ years in the diagnosis group and $57.38{\pm}16.88$ years in the missed fracture group. For the diagnosis group, the mean ISS was $9.03{\pm}8.26$, but in the missed fracture group it was $17.53{\pm}9.69$. Missed fractures were much more frequent in the not-alert mentality (p<0.01) and in the high (ISS$ ISS{\geq}16$) group (p<0.01). Conclusion: Missed fractures occur most frequent in patients of old age, not-alert mentality, and high ISS. Multiple rib and spine fractures were found to be the most frequent missed fractures, regardless of trauma severity. This study also shows a high possibility of clavicle and scapula fractures in patients with severe trauma.

Objective : Avascular necrosis (AVN) of the vertebral body is known as a relatively uncommon phenomenon in a vertebral compression fracture (VCF). The outstanding radiologic findings of AVN are intravertebral vacuum phenomenon with or without fluid collection. Several reports revealed that PVP or balloon kyphoplasty might be the effective treatment modalities for AVN. We also experienced excellent results when using PVP for the treatment of AVN of the vertebral body, and intend to describe the treatment's efficacy in this report. Methods : Thirty-two patients diagnosed with AVN of the vertebral body were treated with PVP. We measured the pre- and post-operative anterior body height and kyphotic angulation. The visual analogue scale (VAS) was used to determine the relief of back pain. Results : The anterior body height (pre-operative : 1.49 cm, post-operative : 2.22 cm) and kyphotic angulation (pre-operative : 14.47 degrees, post-operative : 6.57 degrees) were significantly restored (p<0.001). VAS was improved from 8.9 to 3.7. Pseudoarthrosis was corrected in all cases, which was confirmed by dynamic radiographs. Fluid collection was found in sixteen cases and was aspirated with serous nature. No organism and tumor cell were noted. Conclusion : PVP proved to be an effective procedure for the treatment of AVN of the vertebral body, which corrected dynamic instability and significantly restored the anterior body height and kyphotic angulation.

This study was desingned to investigate the relationships between bone mineral density(BMD) of the lumbar spine($L2\rightarrowL4$) and menopausal symptoms, health conciousness, bone health status, activity intensity, preference of food saltiness in 41 postmenopausal women. Lumbago was main menopausal symptom, and BMD of the subjects with lumbago was significantly low compared with BMD of the subjects without lumbago(p<0.01). BMD of the subjects who felt healthy was significantly higher than BMD of them who felt inbetween or weak(p<0.05). BMD of the subjects who had good bone status of the lumbar spine was significantly higher than BMD of them who had bent lumbar spine or experienced bone fracture(p<0.001). BMD of the subjects who were active was significantly higher than BMD of them whose activity was moderate or sedentary(p<0.05). BMD of the subjects who preferred very insipid taste was significantly high compared with BMD of them who preferred insipid, moderate or salty taste, and BMD of the subjects who preferred very salty taste was significantly low(p<0.01). This study suggested that decrease of BMD of the lumbar spine was significantly related to lumbago, bone fracture and bent lumbar spine. And when they were active and not preferred salty taste, bone loss of the lumbar spine was decreased.

Purpose: Missing cervical pathology after injury may lead to disability and influence long-term survival. Controversies continue to evolve concerning the initial screening methods used to predict cervical spine injury. Through a retrospective chart review, we attempted to analyze and propose factors predictive of cervical trauma. Methods: Of all the patients who had visited the Emergency Department of Korea University, from January 2009 to December 2009, a retrospective review of the clinical records of the 217 patients who had undergone cervical spine computed tomography was done. We investigated whether we could predict the need for cervical spine computed tomography shortly after presentation in trauma patients by comparing the group with fractures and group without fractures and by finding risk factors showing significant differences between the two groups that might be used as guides in decision making. Results: Of the 217 subjects who underwent cervical spine computed tomography scans, 33 were identified with fractures of the cervical spine while 184 were not. The most common mechanisms of trauma, in order, for those with fractures were falls, followed by traffic accidents. We found that the injury severity score, multiple injuries, a high-energy injury mechanism, neurologic deficit, and pain and tenderness of the cervical spine showed statistically significant differences between the two groups. Conclusion: Fractures of the cervical spine that are not observed with simple radiography occur with a relatively high frequency in trauma patients. Consideration should be given to the risk factors for cervical spine fracture, and if pertinent, cervical spine computed tomography should be performed with speed for early diagnosis of cervical spine fractures.

A case of nonsecretory multiple myeloma in a 66 year-old-woman is reported. At first, she complained severe neck pain and radiologic finding showed C2 pathologic fracture. She complained severe low back pain 4 month later and L1 compression fracture was found. The lumbar MRI showed a 1.4cm-sized round enhancing lesion in the body of T12. Bone marrow aspiration biopsy at L1 spine showed a few polymorphous and small nests of mononuclear cell. L1 lamina bone biopsy showed many abnormal plasma cells. Pathologic diagnosis was multiple myeloma. However, plasma electrophoresis and protein immunoelectrophoresis of serum and urine of patient were normal. So, it is a nonecretory multiple myeloma case and the incidence of nonsecretory multiple myeloma is known to about 1% of all multiple myeloma.
