Cocked up hallux following lateral wedging for peroneal symptoms

    Patient is a 40 year old rugby coach with bilateral lateral lower leg and lateral foot pain, worse on left side, over last few months when whenever he is on his feet. Stands with marked bilateral rear foot varus, more marked on the left, plantarflexed first rays but average medial longitudinal arches. Forefoot to rearfoot position is valgus. Many ankle inversion sprains as a child. Varus heel position is fully correctable with coleman block test.

    Wearing Frelen insoles with lateral and forefoot 4 deg lateral wedging is comfortable and he feels that his feet are 'well balanced' for the first time. He can even run up and down the pitch.

    However when he rests his feet ache laterally and first thing inthe morning both halluces are cocked up and stiff so that he has to stretch them down - then they can function.

    Question is - how can I now progress him and reduce the aching when he rests and prevent the ?EHLs from dominating the hallux position.

    Any thoughts please?

    Without seeing the foot or the insoles, I think the lateral discomfort could be either overposting on the lateral side or more likely the 1st met doesn't have enough space to drop down into and is pushing him back to the lateral side. Try a flat 1/8 addition to the base, with a submet 1 cutout extending distal to the end of the insole. However,this may make his shoes very snug.
    The ehl cramps are probably due to the fact that he needs to overuse them for clearance in swing phase. If this is the case can therapy give him more ankle dorsiflexion, if not a shoe with higher heel height and greater forefoot rocker will give him more clearance and lower the demands on the ehls for clearance.

    I'd agree with the over posting comment. A possible explanation of the cocked up hallux is increased FHL use to incease medial load to offset the too high load. Ask the patient to stand and evert their foot without moving their leg and look at the height off of the ground along the 5th metatarsal. Is the forefoot valgus wedge higher than that height? I've made too big of a wedge before and have seen the lateral forefoot ache.

    Cheers,

    Hi
    What is the STJ axis in the transverse plane position? On rest can you see his peroneal brevis tendon? Anterior talus (in talo-crural) and distal fibula tender?
