The efficacy and role of bunion braces include the following: First, bunion braces, can make bunions corrected and avoid bunions outward, but not all braces are able to correct all bunions. For example, if the bunion is particularly long, the bunion brace will not work well at this time and surgery may be required. Second, bunion braces can reduce local pressure and edema and have the effect of relieving pain. Because the bunion orthosis can correct the bunion inward, this time the bunion will not press on the second finger, and this time the second finger will not be painful. Also, after the bunion is corrected, the inflammation of the metacarpophalangeal joint of the thumb will be reduced and the pain will be relieved. However, for some severe bunions, bunion braces are not effective.
