Foot Orthotics and Weakening of Muscle Strength?

If you view 20+ years of surgical experience, rerouting the intrinsic muscles and observing the postop biomechanical impact on gait, not significant research data, then no.

 

To be fair Brian, when I looked at your orthotics site you didn't mention the intrinsic foot muscles or strengthening them at all . Please correct me if I am wrong.

I know little of foot surgery and its outcomes, but am interested to learn a little bit more. Specifically, what are your views of surgical detachment/ attachment relocation of the adductor hallucis in hallux valgus cases. Where I am coming from with this question is that in the habitually shod foot the adductor hallucis likely acts to reduce HAV angle, not increase it .

 

I would shorten the horizontal branch (tendon) of the Adductor Hallucis. Post op It held with Rothbarts foot but failed with the PreClinical Clubfoot Deformity (typically within 5 years postop).

Other than trauma or infectious diseases, HV is a symptom of forefoot hypermobility. Post op if you do not attenuate/eliminate the forefoot hypermobility, the HV deformity will reoccur.

Forefoot hypermobility is not severe with Rothbarts foot. It is very severe with the PreClinical Clubfoot Deformity.

 

I am intrigued . Why would you shorten the tendon of the transverse head ( horizontal branch ?) of the adductor hallucis ?
