Osteoporosis is characterized by bone loss and mobidity with osteoporotic fracture. This study was performed to evaluate the effect of on the bone mass and its related factors in estrogen-deficient animal model. The model rats of osteoporsis showed a significant decrease in bone density, bone ash density, calcium content of femur bone. At the 14th day after ovariectomy-surgery, rats were administered with DBE, extract of Dioscorea batatas, per orally, and continued for 10 weeks. And osteoporosis related parameters were determined to investigate the effect of DBE. Osteoporetic rats showed lower serum estrogen level, higher body weight than normal rats, and showed atrophy of uterine horns. DBE showed inhibitory effect on bone loss in osteoporetic condition, and reduced the increase of ALP activity and osteocalcin level in serum, and reduced the increase of OH-proline level in urine. But, DBE had no effect on cell proliferation and ALP activity in rat calvarial cell culture.

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.

We present here the case of a 13-year-old male patient with Alexander's disease who underwent surgical correction of a femur fracture. Alexander's disease is a rare and fatal disorder that affects the white matter in the brain and it causes developmental delay, psychomotor regression, spasticity, megaloencephaly and seizure. The patient had the possibility of a seizure attack during the perioperative period. We discuss the anesthetic management of a patient with Alexander's disease and we review the relevant literature.

Two different unusual cases of acute sciatic neuropathy are described. They appeared to have been caused by complications from a procedure performed on a patient in the lithotomy position, and an uncertain etiology associated with either a previous femur fracture or a recent blunt trauma to the buttock. Comprehensive histories of weakness, with radiographic or electrophysiological studies, or even exploratory surgery are important in order to understand the etiologies of the sciatic neuropathies.

Purpose: As the number of total knee arthroplasties (TKAs) increases, the incidence of femoral periprosthetic fractures after TKA is also increasing. This review aimed to suggest a new surgically oriented classification system for femoral periprosthetic fractures. Methods: We investigated the classifications, and current treatment trends for femoral periprosthetic fractures after TKA by means of a thorough review of the relevant literature. Results: Numerous studies reported good results of surgical treatment with modern fixatives including locking compression plates and retrograde intramedullary nails. However, few classifications of femoral periprosthetic fractures reflect the recent developments in surgical treatment. Conclusions: We recommend that surgical management be considered the first-line treatment for femoral periprosthetic fractures after TKA. Our new classification will help in deciding the surgical treatment option for femoral periprosthetic fractures after TKA.

A male patient weighing 2.5 kg was admitted for respiratory difficulty, and a large ventricular septal defect (VSD) was diagnosed. During care, sudden right leg swelling with a femur shaft fracture occurred. The patient's father had a history of recurrent lower extremity fractures; thus, osteogenesis imperfecta was considered. The patient's respiratory difficulty became aggravated, and VSD repair in the neonatal period was therefore performed with gentle sternal traction and great vessel manipulation under total intravenous anesthesia to prevent malignant hyperthermia. The patient was discharged without notable problems, except minor wound dehiscence. Outpatient genetic testing revealed that the patient had a COL1A1/COL1A2 mutation.

Purpose: The study was to identify influencing factors on fear of falling in postmenopausal women. Methods: With a correlational survey design, 125 postmenopausal women were recruited at the D metropolitan city by a convenience sampling. Fracture risk status was assessed by bone mineral densities (BMD) at lumbar and femur with DEXA method. A structured study questionnaire was used to measure demographic variables, osteoporosis self-efficacy, and fear of falling. Results: Mean age of the subjects was 59 years old and duration since menopause was 9.55 years. Twenty six percent of the subjects belonged to osteoporotic group in fracture risk status. Mean score for fear of falling was 16.10 (SD=5.18) indicating low level, and osteoporosis self-efficacy for exercise and diet was 44.76 (SD=7.41), indicating mid-range level. Factors influencing the fear of falling was longer time since menopause ($\beta=.30$), lower score of osteoporosis self-efficacy for exercise ($\beta=-.26$), poor health perception status ($\beta=-.16$), and presence of chronic disease ($\beta=.16$), and the explained variance was 20%. Conclusion: Although the level of fear of falling was yet low in postmenopausal women, women who had lower self-efficacy of osteoporosis for exercise and poorer health perception felt greater fear of falling. Therefore, an educational program specific to improve osteoporosis self-efficacy and reduce the fear of falling is needed for improving postmenopausal women's psychosocial well-being.

Purpose: We report the surgical outcomes for femoral shaft fractures in polytrauma patients who were temporarily treated with external fixation and subsequently converted to internal fixation. Methods: From August 2008 to April 2012, we enrolled 13 patients with multiple traumas due to high-energy injuries and concurrent femoral shaft fractures in which temporary external fixation was carried out. The mean age was 39 years, with a range from 18 to 55 years. Ten were men and 3 were women. According to the AO/OTA classification of fractures, type A was found in 5 patients, type B in 6, and type C in 2, with open fractures being found in 6 patients and femoral artery rupture occurring in 2. For internal fixation, intramedullary nailing was performed in 7 patients, and minimally-invasive fixation of locking compression plates was used in 6. Results: Of the 7 patients converted to intramedullary nailing, 1 experienced delayed union. Of the 6 patients treated with minimally-invasive plate fixation, delayed union occurred in 5, and an auto-bone graft was performed within, on average, 8 months (range: 5~10 months), leading to bone union in all cases in the final follow-up. None of the patients experienced infections or complications involving other organs after having been converted to internal fixation. During the mean follow-up of 19 months, patients achieved satisfactory functional outcomes. Conclusion: In polytrauma patients with a femoral shaft fracture who have been treated with temporary external fixation and who may need internal fixation due to the occurrence of delayed union, an appropriate internal fixation method needs to be selected based on the patient's physical status, and the fracture type.

Purpose: Cephalomedullary (CM) nailing is widely performed in treatment of elderly patients with femoral intertrochanteric fractures. However, in cases of fixation failure, re-operation is usually necessary, thus determining factors that may contribute to fixation failure is important. In this study, we examined factors affecting the occurrence of fixation failure, such as age or fracture stability, after CM nailing in elderly patients. Materials and Methods: This study was conducted retrospectively using registered data. From April 2011 to December 2018, CM nailing was performed in 378 cases diagnosed with femoral intertrochanteric fractures, and 201 cases were finally registered. Cases involving patients who were bed-ridden before injury, who died from causes unrelated to surgery, and those with a follow-up period less than six months were excluded. Results: Fixation failure occurred in eight cases. Comparison of the surgical success and fixation failure group showed that the mean age was significantly higher in the fixation failure group compared with the control group (81.3±6.4 vs. 86.4±6.8; P=0.034). A significantly high proportion of unstable fractures was also observed (139/54 vs. 3/5; P=0.040), with a significantly high ratio of intramedullary reduction (176/17 vs. 5/3; P=0.034). A significantly higher ratio of unstable fractures compared with that of stable fractures was observed in the intramedullary reduction group (132/49 vs. 10/10; P=0.033). Conclusion: Fixation failure of CM nailing is likely to occur in patients who are elderly or have unstable fracture patterns. Thus, care should be taken in order to avoid intramedullary reduction.

목적: WHO (world health organization)에서는 골밀도뿐만 아니라 대규모 역학연구에서 정리된 골절의 위험인자 분석을 통하여 10년 내 골절위험도(10-year fracture probability)를 실제적으로 임상에 적용시킬 수 있는 소프트웨어 프로그램인 FRAX Tool (fracture risk assessment)이 2008년에 공개되었다. 본 연구는 기존에 사용하고 있는 GE Prodigy사의 골절위험도평가와 $FRAX^{TM}$를 이용한 골절위험도평가를 비교분석하고자 한다. 검사방법: 본원에 골밀도 검사를 시행한 201명($55{\pm}3.5$세)의 여자를 대상으로 GE Prodigy를 이용하여 Femur를 측정하였다. 측정한 Femoral Neck의 BMD (bone mineral density)를 구하여 GE Prodigy의 T-값과 골절위험인자를 고려하지 않은 $FRAX^{TM}$의 T-값를 사용하여 10년 내 대퇴골 골절위험도와 주요한 골다공증성 골절 위험도를 계산하여 SPSS통계프로그램으로 GE Prodigy의 골절위험도 평가와 $FRAX^{TM}$의 골절위험도 평가를 비교분석하였다. 결과: GE Prodigy의 T-값($-0.52{\pm}0.97$)과 $FRAX^{TM}$의 T-값 ($-1.45{\pm}0.81$)은 통계적으로 유의한 차이가 있었으며(p=0.000), GE Prodigy의 주요한 골다공증성 골절위험도($9.15{\pm}3.71$)와 $FRAX^{TM}$의 주요한 골다공증성 골절위험도($4.87{\pm}1.51$)도 또한 통계적으로 유의한 차이가 있었다(p=0.000). 그리고 GE Prodigy의 10년내 대퇴골 골절위험도($1.56{\pm}1.48$)와 $FRAX^{TM}$의 10년 내 대퇴골골절위험도($0.53{\pm}0.61$)도 통계적으로 유의한 차이를 보였다(p=0.000). 결론: GE Prodigy와 $FRAX^{TM}$에서 측정한 골절의 절대위험도는 통계적으로 유의한 차이를 보였다. 특히 GE Prodigy의 T-값, 주요한 골다공증성 골절위험도, 10년 내 대퇴골 골절위험도가 높게 측정되었다. 향후 $FRAX^{TM}$에 대한 평가 및 적용에 관한 연구가 필요할 것으로 생각된다.
