Modular Head

The TST Modular Head is used in conjunction with the bipolar head in the treatment of femoral head fractures. Thanks to the different size options, optimum placement of the modular head in the acetabulum are ensured. It is preferred because of the short operation time and the prevention of dislocation of large diameters.


  • It offers 2 different options made from CrNi and CoCrMo raw materials.
  • Modular heads in different size options allow the surgeon to overcome the difficulties that originate during the application.



  • Femoral head fracture,
  • Avascular necrosis,
  • Hemi-arthroplasty or partial hip replacement,
  • Replace only the femoral head and neck,
  • Non-inflammatory degenerative articular disease including osteoarthritis, osteonecrosis, avascular necrosis, and post-traumatic arthritis,
  • Rheumatic articular inflammation,
  • Correction of secondary arthritis and functional deformity in various diseases and anomalies such as congenital hip dysplasia or ankylosing spondylitis,
  • The treatment of proximal femoral nonunion, femoral neck fracture, and trochanteric fractures of the proximal femur with head involvement.
