About two thirds of all Achilles tendon ruptures occur during sports. Total ruptures are most common in sports with stop-and-go movements, especially ball sports. The majority of patients suffered a ruptured Achilles tendon when stopping suddenly during a fast vigorous movement. Usually the Achilles tendon tears about 5 cm before it inserts into the heel bone. Particularly at risk for a tear are athletes who have already suffered from Achilles tendon problems for some time.Causes
The causes of an Achilles tendon rupture are very similar to Achilles tendinitis. Causes include. Running uphill. Running on a hard surface. Quickly changing speeds from walking to running. Playing sports that cause you to quickly start and stop.Symptoms
Following are a few of the symptoms usually associated with an Achilles tendon rupture. Sudden, severe pain, swelling, bruising, difficulty walking. Sometimes a gap may be felt in the tendon. The most common ways an Achilles tendon rupture is diagnosed are clinical history (presenting symptoms). Thompson or Simmonds? test, positive if when squeezing the calf there is no foot movement (passive planter flextion). O?Brien?s test, needles are placed into the tendon; tendon is intact if when the foot is moved up and down, the needle hub moves in the same direction as the toes (opposite direction of the tendon) Ultrasound and MRI, because these technologies involve an added expense, they are usually employed only to confirm the diagnosis.Diagnosis
A typical history as detailed above together with positive clinical examination usually will clinch the diagnosis. In an acute rupture, one can usually feel the gap in the tendon from the rupture. There may be swelling or bruising around the ankle and foot of the injured leg. With the patient lying on the tummy (prone position) with the knee flexed, the examiner should see the ankle and foot flex downwards (plantarward) when squeezing the calf muscles. If there is no movement in the ankle and foot on squeezing the calf muscle, this implies that the calf muscle is no longer attached to the heel bone due to a complete Achilles tendon rupture.Non Surgical Treatment
There is no definitive protocol for conservative management. Traditionally, conservative treatment involved immobilisation in a cast or boot, with initial non-weight bearing. Recently, good results have been achieved with functional bracing and early mobilisation, and it is common to be immediately weight-bearing in an orthotic. Conservative management reduces the chance of complications, such as infection. There is a risk the tendon can heal too long and more slowly.Surgical Treatment
Operative treatment of Achilles tendon ruptures involves opening the skin and identifying the torn tendon. This is then sutured together to create a stable construct. This can be performed through a standard Achilles tendon repair technique or through a mini-incision technique (to read about the different types of techniques, look under ?Procedure? in Achilles Tendon Repair). By suturing the torn tendon ends together, they maintain continuity and can be mobilized more quickly. However, it is critical to understand that the return to normal activities must wait until adequate healing of the tendon has occurred. The potential advantages of an open repair of the Achilles tendon include, faster recovery, this means that patients will lose less strength. Early Range of Motion. They are able to move the ankle earlier so it is easier to regain motion. Lower Re-rupture Rate. The re-rupture rate may be significantly lower in operatively treated patients (2-5%) compared to patients treated non-operatively (8-15%). The main disadvantage of an open repair of the Achilles tendon rupture is the potential for a wound-healing problem which could lead to a deep infection that is difficult to eradicate, or a painful scar.
