Modified Anterolateral Approach

The modified anterolateral approach is the most commonly used approach in contemporary hip replacement surgery.

What is it?

The patient is placed on her side and a straight incision of about 10 centimetres is made down the thigh centred on the greater trochanter. The muscle beneath the incision is cut along the length of the fibres. When the gluteus medius and vastus lateralis (both muscles) are cut the joint capsule can be seen. The capsule is then cut open and the hip joint is replaced.

Advantages

  • It is relatively quick
  • The amount of blood lost is less than with some other approaches (ie anterior and trochanderic)
  • The rate of post-operative dislocation is low
  • Rehabilitation is quick
  • The patient will have a good range of movement

Disadvantages

  • Access to the joint is not as good as in the original lateral approach (which involved removal of the trochanteric)
  • There is a risk of damage to the superior gluteal nerve
  • There is a risk of post-opeartive muscle weakness causing abduction and a limp

How is it done?

The best way to learn about a surgical technique is to do it yourself but most of us aren't going to be given that opportunity. Don't be disheartened though because I have found a wonderful - online do-it-yourself hip replacement program which you can play with.
