Abstract
This work was planned to study the ranges of foot angles among the normal feet of adult Egyptians
The material of this study was 250 feet of the adult age group from 20 years to 60 years divided into 4 age groups with an overall mean of 38.3+-10.8 years.
All cases included in this study were of normal feet according to clinical examination, free from foot deformities and systemic disorders affecting the foot normality.
Both sexes were represented equally in the study, there were 125 feet for females and 125 feet for males with a ratio of 1 : 1.
In our stud we used the the routine radiological examination which include : the ordinary anteroposterior and lateral views for all cases.
In our study we had measured the height and the weight of each case , both with the age of the case we had tried to correlate them with the measured angles.
A schedule of angular measurements were applied for each case that included:
For the antero-posterior view: the talo-calcaneal angle, the calcaneo-fifth metatarsal angle, the talo-first metatarsal angle, the first-second metatarsal angle, the distal metatarsal articular angle and the proximal metatarsal articular angle.
For the lateral view: the tibio-calcaneal angle, the tibio-talar angle, the talo-calcaneal angle, the talo-horizontal angle, the calcaneal pitch angle and Bohlar tuber angle.
from the collected data the normal range for each angle was estimated, the means and the standard deviation were calculated and all these data represented in the form of tables.
The informations from the data were correlated to different factors as the age of the patient, the height and the weigh. The age was found to be significant in the antero-posterior talo-first metatarsal angle (p=0.0001) with a negative correlation and in the antero-posterior first-second metatarsal angle (p=0.0001) with a positive correlation whereas the height was significant in the lateral tibio-talar angle (p=0.007) with a positive correlation. These were the only significant events we had found in our study.
The clinical significance of each angle was studied in details and it was found that the measurement of the radiographic angles of the foot and the knowledge of their normal ranges is a useful tool in assessment of foot abnormalities as it is easy, readily, available and has a good accuracy, and so, can be used in conjunction with the other diagnostic methods. Also, it can be used in pre and postoperative assessment of foot deformities.
