Bunions are one of the most common foot deformities and one that many Marathon runners probably experience. This is the second in in Dr. Tariq Khan´s guide to common running woes brought to you in conjunction with Carnation Footcare (www.carnationfootcare.co.uk). Here is what Dr. Tariq Khan has to say:
You’ll feel tenderness over the inner side of the joint between your first metatarsal (MT) and big toe, or hallux, and notice that the end of the toe starts to point outwards, forming an angle of up to 90 degrees with the MT. Pressure of any sort over the joint can cause both redness and pain.
The deformation is obvious, and underlying this will be wear and eventual arthritis of the first metatarso-phalangeal (MTP) joint. The space opened out by the splitting of the joint is filled by a thick-walled bursa – the bunion. Bunion-sufferers often lose their transverse arch under the metatarsal heads, which exaggerates the problem.
