Adult acquired flatfoot deformity (AAFD) is a painful condition resulting from the collapse of the longitudinal (lengthwise) arch of the foot. As the name suggests, this condition is not present at birth or during childhood. It occurs after the skeleton is fully matured. In the past it was referred to a posterior tibial tendon dysfunction (or insufficiency). But the name was changed because the condition really describes a wide range of flatfoot deformities. AAFD is most often seen in women between the ages of 40 and 60. This guide will help you understand how the problem develops, how doctors diagnose the condition, what treatment options are available.
Many health conditions can create a painful flatfoot, an injury to the ligaments in the foot can cause the joints to fall out of alignment. The ligaments support the bones and prevent them from moving. If the ligaments are torn, the foot will become flat and painful. This more commonly occurs in the middle of the foot (Lisfranc injury), but can also occur in the back of the foot. In addition to ligament injuries, fractures and dislocations of the bones in the midfoot can also lead to a flatfoot deformity.
Pain and swelling around the inside aspect of the ankle initially. Later, the arch of the foot may fall (foot becomes flat), this change leads to walking to become difficult and painful, as well as standing for long periods. As the flat foot becomes established, pain may progress to the outer part of the ankle. Eventually, arthritis may develop.
Observe forefoot to hindfoot alignment. Do this with the patient sitting and the heel in neutral, and also with the patient standing. I like to put blocks under the forefoot with the heel in neutral to see how much forefoot correction is necessary to help hold the hindfoot position. One last note is to check all joints for stiffness. In cases of prolonged PTTD or coalition, rigid deformity is present and one must carefully check the joints of the midfoot and hindfoot for stiffness and arthritis in the surgical pre-planning.
Non surgical Treatment
Options range from shoe inserts, orthotics, bracing and physical therapy for elderly and/or inactive patients to reconstructive surgical procedures in those wishing to remain more active. These treatments restore proper function and alignment of the foot by replacing the damaged muscle tendon unit with an undamaged, available and expendable one, lengthening the contracted Achilles tendon and realigning the Os Calcis, or heel bone, while preserving the joints of the hindfoot. If this condition is not recognized before it reaches advanced stages, a fusion of the hindfoot or even the ankle is necessary. Typically this is necessary in elderly individuals with advanced cases that cannot be improved with bracing.
For patients with a more severe deformity, or significant symptoms that do not respond to conservative treatment, surgery may be necessary. There are several procedures available depending on the nature of your condition. Ligament and muscle lengthening, removal of inflamed tendon lining, transferring of a nearby tendon to re-establish an arch, and bone realignment and fusion are examples of surgical options to help with a painful flatfoot condition. Surgery can be avoided when symptoms are addressed early. If you are feeling ankle pain or notice any warmth, redness or swelling in your foot, contact us immediately. We can create a tailored treatment plan to resolve your symptoms and prevent future problems.
