The most serious bunions are treated with a joint-fusion surgical procedure known as a lapidus bunionectomy, in which the first metatarsal and the next boneback, a cuneiform, are fused together.
Louis Saha has been plagued by hamstring trouble which has restricted him to 14 matches this season, while midfielder Marouane Fellaini is playing with a cracked bone in his back.
The most frequent procedure to correct the angular deformity is an osteotomy, or abone cut at either the front, middle or back portion of the first metatarsal bone.
