Objective : The purpose of this study was to determine the efficacy of bone cement-augmented short segment fixation using percutaneous screws for thoracolumbar burst fractures in a background of severe osteoporosis. Methods : Sixteen patients with a single-level thoracolumbar burst fracture (T11-L2) accompanying severe osteoporosis treated from January 2008 to November 2009 were prospectively analyzed. Surgical procedures included postural reduction for 3 days and bone cement augmented percutaneous screw fixation at the fracture level and at adjacent levels without bone fusion. Due to the possibility of implant failure, patients underwent implant removal 12 months after screw fixation. Imaging and clinical findings, including involved vertebral levels, local kyphosis, canal encroachment, and complications were analyzed. Results : Prior to surgery, mean pain score (visual analogue scale) was 8.2 and this decreased to a mean of 2.2 at 12 months after screw fixation. None of the patients complained of pain worsening during the 6 months following implant removal. The percentage of canal compromise at the fractured level improved from a mean of 41.0% to 18.4% at 12 months after surgery. Mean kyphotic angle was improved significantly from $19.8^{\circ}$ before surgery to 7.8 at 12 months after screw fixation. Canal compromise and kyphotic angle improvements were maintained at 6 months after implant removal. No significant neurological deterioration or complications occurred after screw removal in any patient. Conclusion : Bone cement augmented short segment fixation using a percutaneous system can be an alternative to the traditional open technique for the management of selected thoracolumbar burst fractures accompanied by severe osteoporosis.

Osteoporosis is a worldwide problem and it mainly affects postmenopausal women. Osteoporosis associated with pregnancy or lactation is a rare condition. The incidence and mechanism of this phenomenon has not been clarified, but it can cause one or more vertebral compression fractures with severe, prolonged back pain in the affected women. We experienced this uncommon case, treated it with percutaneous vertebroplasty. A 35-old-woman visited our hospital with complaints of severe back pain and flank pain 2 months after normal vaginal delivery. She was diagnosed with osteoporotic vertebral compression fractures on the T5, 8, 9 and 11 vertebral bodies and we performed percutaneous vertebroplasty on the T8, 9 and 11 vertebrae with a good result. We present here an unusual case of pregnancy-associated compression fractures treated by percutaneous vertebroplasty.

A Schmorl's node is defined as a simple endplate intravertebral herniation resulting from trauma or idiopathic causes. Although Schmorl's nodes have been considered clinically insignificant, they might indicate an active symptomatic process or cause serious complications. In this study, we report an interesting case of complete separation of a vertebral body caused by an untreated Schmorl's node accompanying severe osteoporosis. To our knowledge, this is the first clinical report in the published literature to evaluate the complete separation of a vertebral body associated with a Schmorl's node.

Osteoporosis is a major underlying cause of bone fracture in postmenopausal women and older person in general, and so it is a major public health problem. It is a condition in which bone mass decreases, causing bones to be more susceptible to fracture. A trivial trauma can easily cause one or more bones to break in a person with severe osteoporosis. Physicians and patients alike are concerned with the optimum approach to the treatment and prevention of osteoporosis. The diagnostic method and proper use of agents, such as calcium, vitamin D, estrogen, and fluorides, as well as the role of exercise are issues that have generated major research efforts. So these are to be mentioned in this paper.

Bisphosphonate inhibits the function of osteoclast, so they are widely used for multiple myeloma, Paget's disease, metastatic malignant bone disease, and severe osteoporosis. This drug is very effective for preventing severe complication of osteoporosis, some unpredictable complication occurred such as esophageal malignancy, atypical fracture of femur, and osteonecrosis of the jaw. Bisphosphonate related osteonecrosis of the jaw (BRONJ) is closely related with invasive, open bone surgery like tooth extraction. BRONJ associated with dental implant is rare, however, as the use of bisphosphonate increase, BRONJ cases with dental implant are increasing. In this article, we will describe the considerations during dental implant treatment for patient under bisphosphonate therapy.

Osteopotosis is a disease characterized by reduced amount of bone mass leading to enhanced bone flagility. The number of patients with osteoporotic vertebral fracture is increasing and it is one of the leading causes of morbidity in the elderly and postmenopausal women. It is a condition in which bone mass decrease, causing bones to be more susceptible to fracture. A trivial trauma can easily cause one or more bones to break in a person with severe osteoporosis. So it is a major health problem. Pysicians and patients are concerned with the optimum approach to the treatment and prevention of osteoporosis. Until a recent date, many oriental medicine studies were performed to find the preventive and curative efficacy on the osteoporosis, which is differ from therapeutics of Western-medicine. The proper use of Herb-med and role of Accupuncture are issues that have generated major research efforts. This study was carried out to investigate evaluation of clinical and experimental study on the osteoporosis. So, these are to be mentioned in this paper.

[Purpose] Although physical activity is required to prevent or ameliorate osteoporosis, medicine prescription should precede it, since it may be limited in severe osteoporosis patients. Furthermore, osteoporosis has a great effect on physical activity disorders that accompany fractures and pain, and therefore, research on treatment or prevention to decrease the number of patients is required. The purpose of this study was to discover candidate substances from natural products with an effective pharmacological action and to prepare basic data to help patients. [Methods] To prepare the osteoporosis model, ovariectomy (OVX) was performed using surgical methods. The prepared prescription [Shinkiwhan (SKH), a Korean medicine] was administered orally at a dose of 210 mg/kg/day for 8 weeks. After completion of the animal experiment, the bone mineral density (BMD) was analyzed using double-energy X-ray absorptiometry. The analysis of the effect of drugs on bones was performed using histological analysis and immunostaining. [Results] SKH increased the BMD in the OVX rats. Furthermore, SKH significantly increased the expression of osteoprotegerin and downregulated receptor activator of nuclear factor kappa B ligand and phosphorylation of c-jun N-terminal kinases in the bones of the OVX model. [Conclusion] Our findings suggest a protective effect of SKH against BMD loss in the OVX model.

Objective : Severe vertebral body collapse [vertebra plana] is considered a contraindication to vertebroplasty by most authors. The purpose of this study is to determine the efficacy of vertebroplasty in treating severe compression fracture patients with osteoporosis. Methods : 16 patients underwent 18 vertebroplasties following postural reduction for vertebra plana. The fractures were defined vertebrae that have collapsed to more than 75% of their original height. Imaging and clinical features were analyzed, including involved vertebrae level, vertebral height after postural reduction for 2 days, injected cement volume, clinical outcome and complications. Results : Involved veretebra were located from level T7 to L4. Vertebral body collapse averaged 79% [range $12{\sim}25%$] of the original height. After pillow reduction for 2 days, vertebral body height increased 35% of the original height [range $15{\sim}45%$]. The kyphotic wedge was $12^{\circ}$ before procedure and was decreased $7.0^{\circ}$ after vertebroplasty. The mean injected cement volume was 3.8ml [range $2.0{\sim}4.9ml$]. After the procedure, surgical outcome was excellent in 8 [50%] of 16 patients, good in 7 [42%] and unchanged in one [8%]. The mean pain score [VAS score] prior to vertebroplasty was 8.3 and it changed 3.2 after the procure. Cement leakage to the adjacent disc [5 cases] and paravertebral soft tissues [4 cases] developed but there were no major complications. Conclusion : We propose that vertebra plana due to osteoporosis is not a contraindication to vertebroplasty. Vertebroplasty following postural reduction for severe compression fracture is safe and effective treatment.

Objective : The purpose of this study was to determine the efficacy of short segment fixation following postural reduction for the re-expansion and stabilization of unstable burst fractures in patients with osteoporosis. Methods : Twenty patients underwent short segment fixation following postural reduction using a soft roll at the involved vertebra in cases of severely collapsed vertebrae of more than half their original height. All patients had unstable burst fracture with canal compromise, but their motor power was intact. The surgical procedure included postural reduction for 2 days and bone cement-augmented pedicle screw fixations at one level above, one level below and the fractured level itself. Imaging and clinical findings, including the level of the vertebra involved, vertebral height restoration, injected cement volume, local kyphosis, clinical outcome and complications were analyzed. Results : The mean follow-up period was 15 months. The mean pain score (visual analogue scale) prior to surgery was 8.1, which decreased to 2.8 at 7 days after surgery. The kyphotic angle improved significantly from $21.6{\pm}5.8^{\circ}$ before surgery to $5.2{\pm}3.7^{\circ}$ after surgery. The fraction of the height of the vertebra increased from 35% and 40% to 70% in the anterior and middle portion. There were no signs of hardware pull-out, cement leakage into the spinal canal or aggravation of kyphotic deformities. Conclusion : In the management of unstable burst fracture in patients with severe osteoporosis, short segment pedicle screw fixation with bone cement augmentation following postural reduction can be used to reduce the total levels of pedicle screw fixation and to correct kyphotic deformities.

Objective: To analyze osteoporosis treatment patterns and teriparatide prescription-associated factors in Korea by using a national health insurance claims database. Methods: We utilized the Health Insurance Review & Assessment Service National Patients Sample claims database to identify patients (aged ≥50 years) with at least one osteoporosis claim (International Classification of Disease 10th revision code: M80, M81, M82) and at least one prescription for osteoporosis medication (antiresorptive agents: bisphosphonates, selective estrogen receptor modulators, denosumab, and calcitonin; bone-forming agent: teriparatide) in 2018. Demographic characteristics and healthcare utilization patterns were analyzed. Factors associated with teriparatide prescriptions were assessed using a multivariate logistic regression model. Results: Records showed that 44,815 patients were prescribed osteoporosis medications in 2018; the percentage of patients prescribed each treatment was as follows: 86.6% bisphosphonates, 13.9% selective estrogen receptor modulators, 3.1% calcitonin, 2.1% denosumab, and 0.7% teriparatide. A greater proportion of patients prescribed teriparatide were ≥75 years (53.4% vs. 33.8%) and had fractures (63.9% vs. 12.8%) compared to the same for antiresorptives (p<0.001). Patients prescribed teriparatide had higher Charlson comorbidity index values (1.2±1.3 vs. 0.9±1.2) and were more frequently hospitalized (0.8±1.3 vs. 0.1±0.5) than those prescribed antiresorptives (p<0.001). Elderly patients (≥75 years old; adjusted OR=1.66; 95% CI 1.16-2.38) and those with fractures (adjusted OR=6.23; 95% CI 4.76-8.14) were more likely to be prescribed teriparatide than antiresorptives. Conclusion: Patients prescribed teriparatide were older and more likely to have severe osteoporosis than those prescribed antiresorptives.
