Each of the hallux sesamoids are invested in their respective tendons of the flexor hallucis brevis muscle, which, ostensibly is a helper-flexor for the hallux, but in reality acts as more of a stabilizer of the hallux when in the push-off phase of gait. As with all sesamoids, they function to slightly divert the direction of pull of the tendon and in so doing give it a better mechanical advantage. During typical excision of the medial (tibial) sesamoid, some damage to the flexor hallucis brevis tendon in which it is invested is inevitable, and also, depending upon the skill of the surgeon, some weakening of the medial aspect of the first metatarsal joint capsule and the adjacent hallux abductus muscle may result. Due to both of these situations, there is indeed a tendency to allow for some degree of hallux valgus, especially in persons whose bio-mechanics tend toward that deformity anyhow. But all surgery in which some naturally-occurring structure is remove is a trade off between what was and what will hopefully be a better situation. You cannot remove necessary structures without some risk of consequence. It is not always easy or obvious for even an experienced surgeon to determine the long-term effect of his/her surgeries, as the majority of surgical patients are only transient within the practice, and may neither associate delayed untoward effects of the surgery with that surgery nor necessarily return to the same doctor if and when such situations occur. It may be that, in patients who tend to develop bunions mainly due to biomechanical problems related to excessive pronation, the use of orthotic devices may be preventative of problems, but I do not routinely advise my post-sesamoidectomy patients do anything in particular other than to lead normal lives. I certainly would, though, encourage you to discuss this with your own surgeon, rather than taking only the opinion of someone who does not know you, has not examined you nor knows exactly what was done.
