To analyze the performances and the related measurement values for femoro-acetabular impingement on MSCT / 实用放射学杂志

Objective To investigate the performances and characteristics of femoro-acetabular impingement (FAI)on MSCT. Methods Hips jointed MSCT scans of 109 cases (as case group)and the other 120 cases (as control group)were analyzed retrospec-tively,to analyze the anatomy and osseous abnomality of FAI.Alpha angle,offset,CE angle were measured.The data were tested by using t test and ANOVA test.Results There were 57 cases of osseous protuberance at the femoral head and neck joint,26 cases of the offset reduction,17 cases of over-coverage acetabulum,41 cases of over-deep acetabulum,20 cases of acetabular retroversion,57 cases of subcortical cystic degeneration at the femoral head and neck joint and 22 cases of subchondral cystic degeneration at the ace-tabulum margin.Significant statistical differences were found between case group and control group in alpha angle value,offset and CE angle (P<0.05).Multiple comparisons demonstrated that except results between the value of alpha angle of Cam-type and Mixed-type(P=0.071),Pincer-type and the control group(P=0.083)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrated that except result between the value of offset of Cam-type and Mixed-type(P=0.561)with no statistical significance,the differences between any other two groups reached statistical significance (P<0.05).Multiple comparisons demonstrate that except results between the value of CE angle Pin-cer-type and Mixed-type (P=0.444),Cam-type and the control group (P=0.236)with no statistical significance,the differences be-tween any other two groups reached statistical significance (P<0.05).Conclusion Different type of FAI has its unique anatomical features.Alpha angle,offsetand CE angle for the diagnosis of FAI have important reference values.

Treatment of Congenital toe Anomalies / 대한족부족관절학회지

There are many different type of congenital toe anomalies such as syndactyly, polydactyly which are more common, and less frequently macrodactyly and curly toe. Congenital anomaly of hand can decrease the hand function and easy to be visualized, so the early treatment of anomaly is natural and recommended. On the other hand, Congenital anomaly of foot rarely decrease the foot function and was hidden in the shoe, so treatment of anomaly was delayed frequently. However, the surgery can be needed, as the foot getting grown-up, discomfort of shoe fitting or intractable plantar keratosis due to secondary deformation of foot can occur. A distinct feature and surgical consideration was compared with congenital anomaly of hand and it should be taken into account in the treatment of adult toe anomalies.

A Case of Split Hand Split Foot Anomaly

We experienced a case of split hand split foot(SHSF) anomaly in a male neonate who had a deficiency of the middle finger, syndactyly of the 1st and 2nd finger and a deep median cleft in both hands. He also had a deep median cleft between 2nd and 3rd toe, syndactyly of the 1st and 2nd, 3rd and 4th toe without deficiency of the middle toe in both feet. SHSF anomaly may occur either isolated or associated with other anomalies. In this case, it occurd sporadically without family history and showed an isolated type without any other specific anomalies except both posterior iris synechiae. The karyotype of patient showed 46,XY,t(7p:14q) which has not been reported yet. We reported the case with the review of the associated literatures.
