Peroneus tertius 'snapping'

Discussion in 'Biomechanics, Sports and Foot orthoses' started by Simon Spooner, Oct 6, 2009.

    I saw a female runner yesterday with history of chronic lateral ankle instability. O/E pain was elicited by the peroneus tertius tendon snapping over the talar head with STJ supination.

    Does anyone have a copy of this paper they can e-mail me?

    Thanks to Kevin for supplying a copy of the paper. Has anyone any pearls for conservative treatment of this condition?

    As the authors stated "a very rare condition that has not been previously reported".....I've never seen the beast.:drinks

  5. I was thinking about this while finishing some devices this morning

    Heres what I can up with, which I guess most of you will have thought of but here goes

    1 control stj pronation to reduce the tension of the peroneus tertius.

    2 Fit a small varus wedge under the styloid process of the 5th to slightly dorsiflex and evert the base of the 5th to further reduce tension on the peroneus tertius

    3 the extensor retinaculum also needs some help holding down the peroneus tertius, so try taping from medial to lateral over the extensor retinaculum or you could try a swiss ankle brace with laces on the from to put pressure over the retinaculum, but the best idea I thought was you could try one of those velcro bands that people try with patella tendonitis which might help reduce irratation on the achilles tendon and can be adjusted by the patient.

    Just some thoughts .
  6. You mean supination.
    I agree, we will be trying taping after an initial rest period. I think the laced ankle brace might be a little to heavy duty and have been leaning toward a velcro strap version.
  7. Yep sorry Up way to early this morning Supination was want I should have said.

    What do you think about the small wedge good idea or not ?
  8. I'm going to apply valgus forefoot wedging.
  9. Be intersted to know how the patient responds over the next few months.
    Good luck

    Hi Simon

    Interesting case

    I have only seen a couple of these in my time.
    My first question would be, How is the inferior tib fib translation?
    Second is peroneus terious in muscluar dysfunction/Spasm
    My success with this have been based around sup tib-fib and infer tib-fib translation movement second work the affected muscle.

    Finally if these dont work needle the tendon or try spray and stretch.
    If you get these right can be instant resolution.


  11. Not having a good day as Siomon pointed out pronation should be supination and I realised varus should be valgus but the discription is correct. The Wedge I was thinking about whould be about 2cm*2cm and try and focus just on the base of the 5th met.

    Sorry for confusion but could not edit post as time had run out.

    teach me for not proof reading.
  12. Quite. I'd force-quit and re-boot myself if I were you.

    Best wishes,
