Total Hip Replacement for Osteoarthritis Secondary to Hip Dysplasia

Total hip replacement for osteoarthritis secondary to hip dysplasia.

Additive manufacturing orthopaedics has attracted much attention because of its individualized, complex, accurate production and rapid response. Commonly used materials include metal materials such as titanium-based alloys, cobalt-chromium alloys, stainless steel, tantalum and non-metallic materials such as PEEK materials and hydroxyapatite.

Through three-dimensional reconstruction of medical CT data, porous implants with bionic trabecular structures such as joint, spine, craniofacial bone and extremities can be manufactured by using advanced three-dimensional printing techniques like electron beam melting and selective laser melting. Factors such as porosity and pore size can be adjusted for individuals, which is more conducive to bone growth and clinical effect.
