A new instrument was devised to determine the angle between the long axis of the neck and the bicondylar plane of the femur.The superior border of the neck was first determined by a line connecting the two superior ends of the junctions between “head and neck,”and “neck and great trochanter” respectively;the inferior border being determined in similar way.(2)The angle between the superior border of the neck and the bicondylar plane and (3) the angle of the inferior border with the same plane were then measured.(4)The average of the two angles was taken as the angle of torsion of the neck. Three hundred femurs of both sexes were measured.It was found that the angle of torsion of the neck in the adult male is 7.88?,and that in the females is 9.37?.The average value is 8.66?. It was discussed how the angle of torsion in the neck is formed,perhaps it results from the pulling effect of the muscles.

BACKGROUND:Currently, bioactive glass and polylactic acid have been used in clinical dentistry and plastic surgery; however, their therapeutic outcomes are not satisfactory, because the material properties have some limitations. OBJECTIVE:To explore the cytocompatibility of oxygen plasma-treated polylactic acid and bioactive glass guided bone regeneration membrane. METHODS:Bioactive glass and polylactic acid were used as the basic materials to prepare polylactic acid membrane, polylactic acid and bioactive glass composite membrane and oxygen plasme-treated polylactic acid and bioactive glass composite membrane, al of which were used to culture MG63 cels. Cel adhesion rate, cel proliferation rate and alkaline phosphatase activity of MG63 cels on these three kinds of membranes were observed. RESULTS AND CONCLUSION: With the growth of time, in these three groups of membranes, the cel adhesion rate and cel proliferation rate were al significantly increased. Alkaline phosphatase activity showed a decreasing trend after the first increase, and reached its peak at the 7thday of culture. The cel adhesion rate and cel proliferation rate in oxygen plasma-treated polylactic acid and bioactive glass group were significantly higher than those in the other two groups, while the cel adhesion and proliferation rates in polylactic acid and polylactic acid and bioactive glass groups were similar. At the 3rd day of culture, the alkaline phosphatase activity in the polylactic acid and bioactive glass group and oxygen plasma-treated polylactic acid and bioactive glass group was significantly higher than that in the polylactic acid group. At the 7th and 14th days, there was no significant difference in the alkaline phosphatase activity among these three groups. These results show that oxygen plasma-treated polylactic acid and bioactive glass composite membrane has good biocompatibility, which can better promote cel adhesion, proliferation and matrix secretion from osteogenic cels.

Objective To detect the MRI manifestations and discrimination of tuberculous spondylitis and pyogenic spondylitis with atypical features in early stage. Methods Six patients with pathologically proved tuberculous spondylitis and 7 patients of pyogenic spondylitis with atypical clinical features and were included. MRI features of the vertebral bodies, intervertebral discs, paraspinal soft tissues and their enhancement patterns were analyzed. Chi-Square test was used to compare the MRI features of two diseases. Results Patients with pyogenic spondylitis had a significantly higher incidence of disk space narrowing (8 intervertebral bodies), abnormal signal in superior/inferior of vertebral body (12 intervertebral bodies) and endplate with high signal (13 intervertebral bodies), which were not seen in the patients with tuberculosis spondylitis (P<0.05).Patients with tuberculous spondylitis had a significantly higher incidence of local abnormal signal in anterior of vertebral body (4 intervertebral bodies) and paraspinal abscess spanning vertebral body (5 intervertebral bodies), while none of them was found in patients with pyogenic spondylitis (P<0.05). Conclusion MRI is accurate for the differentiation of tuberculous spondylitis and pyogenic spondylitis with atypical feature in early stage.
