A progressive debilitating inflammation/degeneration of the muscle in the shin called the tibialis posterior leading to adult-acquired flat foot deformity. Over time if uncorrected it may lead to joints becoming rigid as the tendon problems affect the areas around them.
IMPORTANT NOTE: degeneration of the tendons starts a long time before the disease becomes noticeable to the person!
Flat foot (pes planus) foot type puts people at risk along with knee problems like “knock-knee” (genu valgum).
The tibialis posterior muscle is the main muscle to hold up the arch and helps the body move forward to the other foot when walking
This muscle can be forced to work harder than it should because of the way the certain bodies are constructed. This can lead to tiny tears in the muscle or tendon and can eventually lead to muscle and ligament failure.
If not managed early enough this problem can lead to deformities such as:
Tight calf muscles.
Middle aged women (up to 10% prevalence)
Extra bones in the foot
Pes planus foot type (flat foot)
Hypertension (high blood pressure)
NSAID’s (Ibuprofen & Nurofen) and changes to activities/exercise and then based on adapted based on which stage:
Immobilization with CAM (Moon boot) 3-4 weeks depending on severity
Stretching as required of associated muscles
Muscle strengthening and rehabilitation thereafter
Surgery if not improved after 3-4 months.
As above but with surgical consultation and with different complexity of surgery depending on the severity of the condition. Ranging from heel bone reduction with tendon repair and reattachment to ankle fusion and re-alignment.
