Measurement of first ray of foot with reference to hallux valgus.
A study was carried out on 58 healthy volunteers. None of the volunteeres had any foot complaints. This was done to study Indian feet, as foot is an important part of human anatomy and its certain deformities eg, hallux valgus, can be very disabling. We have studied anatomical angles between 1st and 2nd rays of foot eg, angle of hallux valgus and angle of slant of distal facet of medial cuneiform and have shown significant correlation between them and development of hallux valgus. The coefficient of correlation (r) calculated between these two angles is significant, showing that this angle influences the angle of hallux valgus and hence development of hallux valgus. These are anatomical angles and indicate shapes of medial cuneiform and 1st metatarsal. Hence these seem to be inherited, making the feet anatomically predisposed to develop hallux valgus. This view is supported by Gray's Anatomy. The extrinsic factors such as narrow toes, closed, footwear worn for an extended period do increase the angle of hallux valgus. So, in predisposed feet, this is one of the extrinsic factor which can lead to development of hallux valgus. On studying these two angles, orthopaedicians should be on alert and should advise such individuals on wearing foot- friendly foot-wear.
