Posterior tibial tendon dysfunction is one of several terms to describe a painful, progressive flatfoot deformity in adults. Other terms include posterior tibial tendon insufficiency and adult acquired flatfoot. The term adult acquired flatfoot is more appropriate because it allows a broader recognition of causative factors, not only limited to the posterior tibial tendon, an event where the posterior tibial tendon looses strength and function. The adult acquired flatfoot is a progressive, symptomatic (painful) deformity resulting from gradual stretch (attenuation) of the tibialis posterior tendon as well as the ligaments that support the arch of the foot.
Arch pain is most often caused by plantar fasciitis, which can affect the heel, arch, or both. Plantar fasciitis treatment is the same, regardless of the location of foot pain (see above). For persistent plantar fasciitis, an injection with a mixture of a steroid and local anesthetic can be helpful. Fallen arches or flat feet occur when the arches of the feet flatten out (often when standing or walking), causing foot pain and other problems. Flat feet can be treated with shoe inserts (orthotics), shoe adjustments, rest/ice, using a walking cane or brace, or physical therapy. Occasionally, surgery is necessary.
Go to a podiatrist at the first sign of symptoms. Besides pain on the bottom of the foot, additional symptoms may include burning sensation in arch, difficulty standing on tiptoes, inflammation, more pain after sleeping or resting, redness, heat, localized pain in the ball of the foot, sharp or shooting pain in the toes, pain that increases when toes are flexed, tingling or numbness in the toes, aching, pain that increases when walking barefoot, pain that increases when walking on hard surfaces, pain the increases when standing (putting weight on your feet) or moving around and decreases when immobile, skin Lesions, it?s important to get a proper diagnosis and treatment plan. Let?s go over the possible causes of the pain.
The doctor will examine your feet for foot flexibility and range of motion and feel for any tenderness or bony abnormalities. Depending on the results of this physical examination, foot X-rays may be recommended. X-rays are always performed in a young child with rigid flatfeet and in an adult with acquired flatfeet due to trauma.
Non Surgical Treatment
High arches that are flexible do not require any treatment. In cases where there is pain, shoe modifications such as an arch insert or support insole can help to relieve pain during walking. Custom orthotic devices can be given that fit into the shoe and provide stability and cushioning effect. Your doctor may recommend a brace to help keep the foot and ankle stable. In severe cases, surgery is performed to flatten the foot. Any coexisting nerve disorders are also treated.
The procedure involves cutting and shifting the bone, and then performing a tendon transfer. First, the surgeon performs a calcaneal osteotomy, cutting the heel bone and shifting it into the correct position. Second, the surgeon transfers the tendon. Reroute the flexor digitorum to replace the troublesome posterior tibial tendon. Finally, the surgeon typically performs one or more fine-tuning procedures that address the patient?s specific foot deformity. Often, the surgeon will lengthen the Achilles tendon because it is common for the mispositioned foot to cause the Achilles to tighten. Occasionally, to increase the arch, the surgeon performs another osteotomy of one of the bones of the midfoot. Occasionally, to point the foot in a straightforward direction, the surgeon performs another osteotomy of the outside portion of the calcaneus.
The best way to prevent plantar fasciitis is to wear shoes that are well made and fit your feet. This is especially important when you exercise, walk a lot, or stand for a long time on hard surfaces. Get new athletic shoes before your old shoes stop supporting and cushioning your feet. You should also avoid repeated jarring to the heel. Maintain a healthy weight. Stretch when you feel a tightening of the ligament that runs along the bottom of your foot. Stop impact sports when symptoms first occur.
Try these simple stretches to assist with relieving pain in your arches. (Note: Stretch slowly and gently. You should feel a moderate pull on the muscle and tendon but no pain. If these stretches are painful, stop and seek further advice from a health professional). STRETCH ONE. Stand at arm?s length from a wall with one foot in front of the other, forward knee bent. Keeping your back leg straight and back heel on the floor, lean into the wall until you feel a stretch in your calf. STRETCH TWO. This time, bend your back leg slightly, and lean into the wall. You should feel a stretch in the lower part of your calf. Hold each stretch for 20 seconds and repeat on each leg, a few times daily.
