What Are Key Causes And Signs Of An Achilles Tendon Rupture

Achilles Tendonitis Many of the muscles that move the foot are found in the lower leg. These muscles attach via tendons to various bones in the foot. The main muscles that move the foot downwards (plantar flex the foot) and propel the body forward are the calf muscles (gastrocnemius and soleus muscles). These muscles are connected to the heel bone (calcaneus) by the "rope like" Achilles tendon. Achilles tendon rupture is the term used to describe a complete tear of the Achilles tendon. The most common site for Achilles tendon rupture to occur is an area 2 - 6 cm. (1 - 2.5 in.) above where the tendon attaches to the calcaneus.

Repeated stress from a variety of causes is often the cause of Achilles tendon injury. The stress may occur from any of the following. Excessive activity or overuse. Flat feet. Poorly fitting or inadequate shoes. Inadequate warm-up or proper conditioning. Jogging or running on hard surfaces. Older recreational athlete. Previous Achilles tendon injury (tendonitis/rupture). Repeated steroid injections. Sudden changes in intensity of exercise. Use of fluoroquinolone antibiotics (especially in children). Trauma to the ankle. Tense calf muscles prior to exercise. Weak calf muscles.

Although it's possible to have no signs or symptoms with an Achilles tendon rupture, most people experience pain, possibly severe, and swelling near your heel. An inability to bend your foot downward or "push off" the injured leg when you walk. An inability to stand up on your toes on the injured leg. A popping or snapping sound when the injury occurs. Seek medical advice immediately if you feel a pop or snap in your heel, especially if you can't walk properly afterward.

In diagnosing an Achilles tendon rupture, the foot and ankle surgeon will ask questions about how and when the injury occurred and whether the patient has previously injured the tendon or experienced similar symptoms. The surgeon will examine the foot and ankle, feeling for a defect in the tendon that suggests a tear. Range of motion and muscle strength will be evaluated and compared to the uninjured foot and ankle. If the Achilles tendon is ruptured, the patient will have less strength in pushing down (as on a gas pedal) and will have difficulty rising on the toes. The diagnosis of an Achilles tendon rupture is typically straightforward and can be made through this type of examination. In some cases, however, the surgeon may order an MRI or other advanced imaging tests.

Non Surgical Treatment
Non-operative treatment consists of placing the foot in a downward position [equinus] and providing relative immobilization of the foot in this position until the Achilles has healed. This typically involves some type of stable bracing or relative immobilization for 6 weeks, often with limited or no weight bearing. The patient can then be transitioned to a boot with a heel lift and then gradually increase their activity level within the boot. It is very important that the status of the Achilles is monitored throughout non-operative treatment. This can be done by examination or via ultrasound. If there is evidence of gapping or non-healing, surgery may need to be considered. Formal protocols have been developed to help optimize non-operative treatments and excellent results have been reported with these protocols. The focus of these treatments is to ensure that the Achilles rupture is in continuity and is healing in a satisfactory manner. The primary advantage of non-operative treatment is that without an incision in this area, there are no problems with wound healing or infection. Wound infection following Achilles tendon surgery can be a devastating complication and therefore, for many patients, non-operative treatment should be contemplated. The main disadvantage of non-operative treatment is that the recovery is probably slower. On average, the main checkpoints of recovery occur 3-4 weeks quicker with operative treatment than with non-operative treatment. In addition, the re-rupture rate appears to be higher with some non-operative treatments. Re-rupture typically occurs 8-18 months after the original injury. Achilles Tendinitis

Surgical Treatment
Debate remains regarding the best form of treatment for a ruptured Achilles tendon. The 2 options are:immobilisation or operation. A recent meta-analysis of scientific studies showed that compared to immobilisation, an operation reduces the risk of re-rupture and allows a quicker return to work. An operation is not without risk and these must be balanced against the benefit of a lower re-rupture rate. Both treatments involve immobilisation for 8 weeks.
