Custom made hip prosthesis

Custom hip prostheses take into account the three-dimensional complexity and interindividual variability of hip anatomy. Precise analysis of this anatomy using 2D X-rays is incomplete: only a 3D analysis using a CT scan is reliable. A custom prosthesis is a personalized implant, designed and manufactured in 3D to faithfully reproduce the anatomy of each patient and promote the most durable optimal biomechanical functioning.

All information, from the onset of the first symptoms to the post-operative recovery, can be found here.


The symptoms of hip pathologies vary, from stiffness to acute pain, and require special attention to determine the underlying pathology.



The consultation is essential for making an accurate diagnosis and considering various treatments for relief. The Inside the Hip team offers its hyper-specialization in hip pathologies to ensure personalized care for you.


3D Scanner

The anatomy of the hip joint is complex and varies greatly from person to person. A hip scan performed according to a specific protocol in an authorized center allows for precise analysis of this anatomy and then the design of a 3D custom implant tailored to each individual case.


Prosthesis Manufacturing

The design and fabrication of a custom hip implant is the result of close collaboration between surgeons and engineers. Once the implant design is validated, it is machined from a block of titanium in Yverdon, at the workshops of Symbios. It thus meets both anatomical and mechanical specifications.


Prosthesis Implantation

The creation of a custom implant designed and manufactured in 3D allows the surgeon to anticipate surgical difficulties. This increases the precision of placement while reducing the risk of mechanical complications. Using an anterior approach respects the musculature of the hip, thus promoting optimal functional results.


Postoperative Care

Hip surgeries are increasingly well-managed. Hospital stays are often short, but the care journey continues after leaving the hospital. To avoid complications and return to normal life, it is important to continue prescribed treatments and to follow the instructions given by the surgeons.



The testimonials of patients treated by the Inside the Hip team allow you to compare your experience with theirs and to dispel any concerns about the various interventions.


Design and 3D Scanning

The design and creation of a custom hip prosthesis is a cutting-edge technology requiring the expertise of a highly specialized medical-industrial team. A CT scan is performed, followed by a 3D reconstruction of the hip. The surgeon defines the reconstruction objectives, tailored to the patient, and sets the specifications. We plan the position of the new rotation center of your hip based on the diameter of the socket and the quality of bone support.

The dimensions, shape, and orientation of the femoral prosthesis are determined by a team of engineers and surgeons to meet the specifications (anatomical adaptation and mechanical strength). After discussions and possible modifications, the design is validated and then the prosthesis is manufactured.

Manufacturing the Prosthesis

The prosthesis is forged from a block of titanium and then machined in Yverdon (Switzerland) at the Symbios factory workshops. The surface treatment of the implant allows for biological bone fixation, ensuring a long lifespan.


The surgical operation is performed via an anterior approach, without any muscle sectioning. The incision is made in front of the hip, then the muscles are moved aside to allow access to the joint. The worn femoral head is resected. The implants are fixed without cement due to immediate mechanical stability. At the end of the operation, the muscles return to their normal position, allowing a resumption of activities without restricted movement.

As a reference technique, the custom prosthesis is indicated when the conventional prosthesis is unsuitable: femoral neck orientation disorder (coxa vara, coxa valga, anteversion, or retroversion), femoral diaphysis malformation, global joint malformation… Patients with extreme dimensions can benefit from it. Finally, the custom prosthesis is the reference in terms of joint reconstruction quality for young and athletic patients.

2D, 3D, or Custom?

The operative planning of a total hip prosthesis on 2D X-rays has shown its limitations:

  • On one hand, it is impossible to know the exact dimensions of the joint (unknown radiological enlargement);
  • On the other hand, the torsion of the hip (orientation of the femoral neck) is unknown.

3D planning on a CT scan provides a solution to these two problems, offering several direct advantages:

  • Prediction of the surgical procedure;
  • Precise restoration of limb length;
  • Precise restoration of hip rotations;
  • Restoration of proper muscle tension, allowing for optimal joint function.

3D finally allows opting for a custom prosthesis if the measurements and orientation of the hip to be operated on are too far from the possibilities of reconstruction with a standard prosthesis. This procedure thus secures the surgical act by reducing mechanical uncertainties.
