Tarsal tunnel versus medial plantar and lateral plantar injury
Hi, I just found this group and hoping to learn from others experiences. July 2020 I had a plantar flexion injury to my foot (my big toe and foot folded under me). I was diagnosed with avulsion fracture of big toe and placed in post-op shoe for 4 wks. I had some bruising along inside of foot, swelling and pain on top of foot, but the podiatrist was dismissive, never examined the foot and said it would be fine. I had worsening pain in midfoot, along medial aspect of foot and swelling for several months. I finally went to sports med doc this spring. I've had x-rays and MRI of foot, ankle, EMG, and nerve US. The MRI showed atrophy of muscles innervated by medial plantar and lateral plantar nerves. The EMG also showed that the motor function of those nerves weren't working, but the sensory aspect was fine. The nerve US didn't show any identifiable entrapment. I've had to advocate for myself to get this far, and still not getting a lot of answers in terms of how this could have happened or what, if anything, can be done. I'm having a difficult time finding a specialist who can help as it seems like an unusual injury. Time is running out for a chance of nerve and muscle recovery, and I'm used to being active so this is hitting me hard.
Has anyone else had injury to motor function of medial plantar and/or lateral plantar nerves and subsequent weakness of foot intrinsic muscles? What type of doc did you see? What treatments helped or didn't help? They were initially thinking tarsal tunnel, but the MRI and US don't show any entrapment. Thanks.
