Résumé
Endcap placement after intramedullary nailing can be cumbersome. Misplacement of the endcap which may be difficult to extract may occur. In this report, a simple Kirschner wire device with 'fish-hook' technique may ease the procedure without further violating bony or soft tissues.

PURPOSE: The authors evaluated the usefulness of the biochemical markers in the elderly hip fracture patients. MATERIALS AND METHODS: Eighty-two hip fractures above 65 years old were enrolled in this study. Serum level of C-telopeptide, osteocalcin, parathyroid hormone, 25-hydroxyvitamin D, calcium were checked and bone mineral density was assessed by DXA. RESULTS: 83% vitamin D deficiency and 43% calcium insufficiency were observed. There were statistically significance between C-telopeptide and osteocalcin, calcium and 25-hydroxyvitamin D, and calcium and DXA results in the Chi-Square test. Spearmann correlation coefficient results showed that there were statically significant correlations between C-telopeptide and osteocalcin, calcium and DXA results. In the multiple logistic regression analysis results, calcium had the statically significant correlations with DXA results. CONCLUSION: There was correlation between bone turnover markers and vitamin D deficiency, and calcium insufficiency was observed in the elderly hip fracture patients.

PURPOSE: The purpose of this study was to evaluate the usefulness of our method, which estimated femoral stem alignment using a c-arm when the broach was inserted, for prevention of femoral stem malalignment. MATERIALS AND METHODS: A total of 103 hips were enrolled in this study. All patients underwentprimary hip arthroplasty from October 2011 to February 2013. The study was conductedretrospectively. Intraoperative estimated femoral stem alignments and final femoral stem alignments were classified into three groups. Multinomial logistic regression analysis was performed for analysis of factors (age, sex, diagnosis, body mass index, femoral stem size, osteoporosis, and proximal demur geometry) thatmight affect intraoperatively estimated femoral stem alignment. RESULTS: The distribution of intraoperative estimated femoral stem alignment was 80(78%) in the neutral group, 18(17%) in the varus group, and 5(5%) in the valgus group. The distribution of final femoral stem alignment was 100(97%) in the neutral group, 2(2%) in the varus group, and 1(1%) in the valgus group. There was no statistically significant factor affecting the intraoperatively estimated femoral stem alignment. CONCLUSION: Intraoperative estimated femoral stem alignment using a c-arm is an effective method for prevention of femoral stem malalignment.
