Relative femoral neck lengthening, restoring hip biomechanics

The indication for a relative lengthening of the femoral neck is usually Legg-Calvé-Perthes disease. In this condition, the outer part of the femur (the greater trochanter) can be positioned too high relative to the femoral head.

The problem with this is that the muscles attached to this outer part have too small a lever arm. As a result, little force can be generated, and the load on the hip joint is not optimal. This can lead to accelerated deterioration of the hip joint cartilage (osteoarthritis).

Furthermore, if a hip arthroplasty needs to be performed later, it is crucial for the outer part of the femur to be in the correct position.

• An incision is made on the side of the thigh.
• The outer part of the thigh bone (greater trochanter) is detached.
• This piece of bone is moved a short distance downwards, so that the hip muscles regain a good lever arm.
• The bone is reattached with 2 to 3 screws.

Our HipCloud application guides and monitors the pre- and post-operative trajectory.

• The bone needs to heal and unite. This takes approximately 6 weeks.
• During these 6 weeks, you are allowed to partially weight-bear, with the aid of 2 crutches.
• After 6 weeks, the bone is sufficiently healed to start rehabilitation.
• Rehabilitation focuses on restoring muscle strength and the normal biomechanics of the hip.

At the European Hip Center, we combine advanced surgical techniques with personalized care. HipCloud, our digital platform, plays an important role in this:

• Before surgery: preparation with education and guidance.
• After surgery: monitoring your recovery and supporting rehabilitation.

This approach ensures a faster and safer recovery, tailored to your personal situation.
