Overview

An Achilles tendon injury can affect both professional and amateur athletes. The Achilles tendon is one of the longer tendons in your body, stretching from the bones of your heel to your calf muscles. You can feel it, a springy band of tissue at the back of your ankle and above your heel. It allows you to extend your foot and point your toes to the floor. Unfortunately, it's a commonly injured tendon. Many Achilles tendon injuries are caused by tendinitis, in which the tendon becomes swollen and painful. In a severe Achilles tendon injury, too much force on the tendon can cause it to tear partially or rupture completely.

Causes
The tendon usually ruptures without any warning. It is most common in men between the ages of 40-50, who play sports intermittently, such as badminton and squash. There was probably some degeneration in the tendon before the rupture which may or may not have been causing symptoms.

Symptoms
Patients present with acute posterior ankle/heel pain and may give a history of ?felt like someone kicked me from behind?. Patients may report a direct injury, or report the pain started with jumping or landing on a dorsiflexed foot. It is important to elicit in the history any recent steroid or flouroqunolone usage including local steroid injections, and also any history of endocrine disorders or systemic inflammatory conditions.

Diagnosis
Laboratory studies usually are not necessary in evaluating and diagnosing an Achilles tendon rupture or injury, although evaluation may help to rule out some of the other possibilities in the differential diagnosis. Plain radiography. Radiographs are more useful for ruling out other injuries than for ruling in Achilles tendon ruptures. Ultrasonography of the leg and thigh can help to evaluate the possibility of deep venous thrombosis and also can be used to rule out a Baker cyst, in experienced hands, ultrasonography can identify a ruptured Achilles tendon or the signs of tendinosis. Magnetic resonance imaging (MRI). MRI can facilitate definitive diagnosis of a disrupted tendon and can be used to distinguish between paratenonitis, tendinosis, and bursitis.

Non Surgical Treatment
To give the best prospects for recovery it is important to treat an Achilles' tendon rupture as soon as possible. If a complete rupture is treated early the gap between the two ends of the tendon will be minimised. This can avoid the need for an operation or tendon graft. There are two forms of treatment available for an Achilles' tendon rupture; conservative treatment and surgery. Conservative treatment will involve the affected leg being placed in a cast and series of braces with the foot pointing down to allow the two ends of the tendon to knit together naturally.


Surgical Treatment
This injury is often treated surgically. Surgical care adds the risks of surgery, there are for you to view. After the surgery, the cast and aftercare is typically as follows. A below-knee cast (from just below the knee to the tips of the toes) is applied. The initial cast may be applied with your foot positioned in a downward direction to allow the ends of the tendon to lie closer together for initial healing. You may be brought back in 2-3 week intervals until the foot can be positioned at 90 degrees to the leg in the cast. The first 6 weeks in the cast are typically non-weight bearing with crutches or other suitable device to assist with the non-weight bearing requirement. After 6 weeks in the non-removable cast, a removable walking cast is started. The removable walking cast can be removed for therapy, sleeping and bathing. The period in the removable walking cast may need to last for an additional 2-6 weeks. Your doctor will review a home physical therapy program with you (more on this program later) that will typically start not long after your non-removable cast is removed. Your doctor may also refer you for formal physical therapy appointments. Typically, weight bearing exercise activities are kept restricted for at least 4 months or more. Swimming or stationary cycling activities may be allowed sooner. Complete healing may take 12 months or more.

Prevention
The best treatment of Achilles tendonitis is prevention. Stretching the Achilles tendon before exercise, even at the start of the day, will help to maintain ankle flexibility. Problems with foot mechanics can also lead to Achilles tendonitis. This can often be treated with devices inserted into the shoes such as heel cups, arch supports, and custom orthotics.

Overview
Often considered solely a product of genetics, flatfoot rarely carries with it the stigma of presenting over time. The truth, however, is that flatfoot does not discriminate on the basis of age and can become an issue in the form of adult-acquired flatfoot. Like its congenital cousin, adult-acquired flatfoot deformity is one that, in causing structural damage to the foot (and particularly to the posterior tibial tendon), creates an imbalance that may result in any number of symptoms, including inflammation, pain, stiffness, limited mobility, and even arthritis.


Causes
Overuse of the posterior tibial tendon is often the cause of PTTD. In fact, the symptoms usually occur after activities that involve the tendon, such as running, walking, hiking, or climbing stairs.

Symptoms
The symptom most often associated with AAF is PTTD, but it is important to see this only as a single step along a broader continuum. The most important function of the PT tendon is to work in synergy with the peroneus longus to stabilize the midtarsal joint (MTJ). When the PT muscle contracts and acts concentrically, it inverts the foot, thereby raising the medial arch. When stretched under tension, acting eccentrically, its function can be seen as a pronation retarder. The integrity of the PT tendon and muscle is crucial to the proper function of the foot, but it is far from the lone actor in maintaining the arch. There is a vital codependence on a host of other muscles and ligaments that when disrupted leads to an almost predictable loss in foot architecture and subsequent pathology.

Diagnosis
Observation by a skilled foot clinician and a hands-on evaluation of the foot and ankle is the most accurate diagnostic technique. Your Dallas foot doctor may have you do a walking examination (the most reliable way to check for the deformity). During walking, the affected foot appears more pronated and deformed. Your podiatrist may do muscle testing to look for strength deficiencies. During a single foot raise test, the foot doctor will ask you to rise up on the tip of your toes while keeping your unaffected foot off the ground. If your posterior tendon has been attenuated or ruptured, you will be unable to lift your heel off the floor. In less severe cases, it is possible to rise onto your toes, but your heel will not invert normally. X-rays are not always helpful as a diagnostic tool for Adult Flatfoot because both feet will generally demonstrate a deformity. MRI (magnetic resonance imaging) may show tendon injury and inflammation, but can?t always be relied on for a complete diagnosis. In most cases, a MRI is not necessary to diagnose a posterior tibial tendon injury. An ultrasound may also be used to confirm the deformity, but is usually not required for an initial diagnosis.

Non surgical Treatment
Nonoperative therapy for posterior tibial tendon dysfunction has been shown to yield 67% good-to-excellent results in 49 patients with stage 2 and 3 deformities. A rigid UCBL orthosis with a medial forefoot post was used in nonobese patients with flexible heel deformities correctible to neutral and less than 10? of forefoot varus. A molded ankle foot orthosis was used in obese patients with fixed deformity and forefoot varus greater than 10?. Average length of orthotic use was 15 months. Four patients ultimately elected to have surgery. The authors concluded that orthotic management is successful in older low-demand patients and that surgical treatment can be reserved for those patients who fail nonoperative treatment.


Surgical Treatment
The indications for surgery are persistent pain and/or significant deformity. Sometimes the foot just feels weak and the assessment of deformity is best done by a foot and ankle specialist. If surgery is appropriate, a combination of soft tissue and bony procedures may be considered to correct alignment and support the medial arch, taking strain off failing ligaments. Depending upon the tissues involved and extent of deformity, the foot and ankle specialist will determine the necessary combination of procedures. Surgical procedures may include a medial slide calcaneal osteotomy to correct position of the heel, a lateral column lengthening to correct position in the midfoot and a medial cuneiform osteotomy or first metatarsal-tarsal fusion to correct elevation of the medial forefoot. The posterior tibial tendon may be reconstructed with a tendon transfer. In severe cases (stage III), the reconstruction may include fusion of the hind foot,, resulting in stiffness of the hind foot but the desired pain relief. In the most severe stage (stage IV), the deltoid ligament on the inside of the ankle fails, resulting in the deformity in the ankle. This deformity over time can result in arthritis in the ankle.
