We report a case of insufficiency fracture of the sternum in a 70-year-old female patient with a review of the literature. She complained of sudden onset chest pain and aggravating dyspnea. She has been managed with corticosteroid due to chronic obstructive pulmonary disease for 15 years. Diagnosis of sternal insufficiency fracture presented with thoracic kyphosis was made on the basis of absence of trauma history, radiologic findings of lateral chest radiograph, bone scintigraphy and chest computed tomography. Thoracic kyphosis and osteoporosis secondary to menopause, corticosteroid therapy and limited mobility due to chronic obstructive pulmonary disease were considered as predisposing factors of the sternal insufficiency fracture in this patient.

OBJECTIVETo investigate the selectivity and individualization of transpedicular balloon kyphoplasty for aged osteoporotic spinal fracture.

METHODSTwenty-two consecutive procedures were performed in 17 aged patients with osteoporotic spinal compression fractures from April 2002 to June 2004. The signal changes in different sequences were confirmed by magnetic resonance imaging before the procedures. This operation involved the percutaneous insertion of two inflatable bone tamps into a fractured vertebral body transpedicularly under fluoroscopic guidance. Every patient was treated individually, according to the results of radiography and CT scan before operation. Preoperative and postoperative complications, visual analogue scale, and radiographic findings such as vertebral height and Cobb angle were recorded and analyzed.

RESULTSAll patients tolerated the procedure well with immediate relief of their back pain in 24 hours. There was no leakage of cement into the epidura. The mean loss percent of the anterior and middle vertebral heights were (35.32 +/- 13.15)% and (27.53 +/- 12.61)% before operation, and (14.21 +/- 12.43)% and (16.2 +/- 7.5)% after operation. The height restoration of vertebra was confirmed by X-ray after the procedure (P < 0.01). The mean kyphosis was improved from (25.3 +/- 4.2) degrees to (8.6 +/- 5.1) degrees. No complications occurred. No patient had nerve injury. The patients were allowed to walk next day after the procedure.

CONCLUSIONThe selectivity and individualization of transpedicular balloon kyphoplasty for aged osteoporotic spinal fractures has satisfactory short-term clinical efficacy. It is also an effective way to prevent complications.

OBJECTIVETo investigate the clinical value of serum total procollagen type 1 aminoterminal propeptide (total P1NP), cross-linked C-terminal telopeptide of type I collagen (β-CTX) and 25(OH)D3 detection in evaluating the risks of fragile hip fracture in elderly patients with osteoporosis.

METHODSSerum levels of total P1NP, β-CTX and 25(OH)D3 was measured in 68 elderly osteoporotic patients with fragile hip fracture and 68 age- and gender-matched osteoporotic controls without fragile hip fracture. In both groups, bone mineral density (BMD) was detected with dual X-ray absorptiometry.

RESULTSThe serum levels of total P1NP and β-CTX were significantly higher and 25(OH)D3 level was significantly lower in fragile hip fracture group than in the control group (P<0.05), but the two groups showed no significant difference in lumbar or total hip BMD. Bivariate correlation analysis suggested that in fragile hip fracture group, serum 25(OH)D3 level was positively, while serum total P1NP and β-CTX levels were inversely correlated with lumbar and total hip BMD (P<0.05). In control group, 25(OH)D3 was not related to lumbar or total hip BMD, and serum total P1NP and β-CTX levels were inversely correlated with total hip BMD (P<0.05) but not related to lumbar BMD.

CONCLUSIONIn osteoporotic elderly patients with close BMD levels, high serum levels of total P1NP and β-CTX and low serum levels of 25(OH)D3 might independently indicate high fragile hip fracture risk, and detection of the three markers can help identify high-risk individuals.

We investigated which of the three FRAX fracture risk assessment tool models is most applicable to Korean women. For 306 postmenopausal women (mean age, 77 yr) with a hip fracture, fracture probabilities were calculated using FRAX models from Japan, Turkey and China. Data on bone mineral density (BMD) at the femoral neck were available for 103 patients. Significant differences existed among the models, independent of the inclusion of BMD in the calculation of fracture probabilities. The probabilities of both major osteoporotic fractures and hip fractures were significantly higher in the Japanese model than in the Turkish or Chinese models. In all of the models, the probabilities of a major osteoporotic fracture, but not of a hip fracture, decreased significantly if calculated without BMD values. By applying the Japanese model, the ten-year probabilities for major osteoporotic and hip fractures increased significantly with age. Our results suggest that the Japanese FRAX model might be the most appropriate for Korean women.

OBJECTIVETo retrospectively investigate the clinical characteristics of sternal insufficiency fractures (SIFs) of post-menopausal women.

METHODSFindings on the clinical presentation, associated diseases, and imaging of SIFs in 17 postmenopausal women admitted to our hospital between February 1999 and January 2009 were reported.

RESULTSTwelve patients complained of severe pain in their anterior chest. Other symptoms included cough (5 cases), dyspnoea (3 cases), breathlessness (3 cases), and wheeze (2 cases). Four patients had no discomfort. The sternums of 11 cases were tender to palpation. Seventeen patients had osteoporosis. Other associated diseases were chronic obstructive pulmonary disease (7 cases), rheumatoid arthritis (3 cases), systemic lupus erythematosus (1 case), asthma (1 case), and thoracic vertebral fracture (13 cases). Nine patients had received glucocorticoid treatment. The fractures were located in the body of the sternum in 15 patients, in the manubrium in 1 patient, and in the manubriosternal junction in 1 patient. Displaced fracture was present in 13 cases. Lateral radiography of the sternum showed a fracture line in 14 patients. In the remaining 3 cases, other imaging examinations such as bone scan, computed tomography or magnetic resonance imaging demonstrated the presence of a fracture.

CONCLUSIONSOsteoporosis, glucocorticoid therapy, chronic obstructive pulmonary disease, and rheumatoid arthritis might be risk factors for SIFs. SIFs should be considered in the differential diagnosis of chest pain.

Percutaneous vertebroplasty (PVP) has been used to relieve pain and to prevent further collapse of the vertebral body in patients with an osteoporotic compression fracture. The most commonly affected site for the use of PVP is the thoracolumbar junction. There are few reports that have described on the usefulness of PVP in the treatment of a high thoracic compression fracture. We report a case of an upper thoracic compression fracture that was treated with computed tomography (CT)-guided PVP. It was possible to obtain easy access to the narrow thoracic pedicle and it was also possible to monitor continuously the proper volume of polymethylmethacrylate employed, under CT guidance.

PURPOSE: Up to 71% of South Korean postmenopausal women have vitamin D deficiency {serum 25-hydroxyvitamin D [25(OH) D] level <50 nmol/L}. Data on vitamin D supplementation was collected during the screening phase of an efficacy/safety study of denosumab in Korean postmenopausal women with osteoporosis. This report describes the effect of vitamin D supplementation on repletion to 25(OH)D levels ≥50 nmol/L in Korean postmenopausal women with osteoporosis. MATERIALS AND METHODS: Vitamin D levels of Korean postmenopausal women (60-90 years old) were measured by extracting 25(OH)D2 and 25(OH)D3 from serum samples via protein precipitation and using liquid chromatography with tandem mass spectrometry detection. Calibration curves were constructed from the mass chromatograms to obtain total vitamin D levels. Subjects with serum 25(OH)D levels <50 nmol/L were supplemented with 1000 IU of vitamin D tablets during the 2.5-month-long screening period. Dose, frequency, and duration were determined by the investigator. If repletion was achieved (≥50 nmol/L) on retest, subjects were eligible to be rescreened for study entry. RESULTS: Of 371 subjects screened, 191 (52%) required vitamin D supplementation, and 88% (168 of 191) were successfully repleted. More than half of the subjects (58%) who were successfully repleted received doses of 2000 IU daily. The mean time to successful repletion was 31 days (standard deviation 8.4 days; range 11-48 days). CONCLUSION: Supplementation with daily median doses of 2000 IU vitamin D successfully repleted 88% of Korean postmenopausal women with osteoporosis within 48 days to a serum vitamin D level of 50 nmol/L.
