Three-dimensional-printing Technology in Hip and Pelvic Surgery: Current Landscape

Area of Science:

• Orthopaedic Surgery
• Biomedical Engineering
• Medical Technology

Background:

• Three-dimensional (3D) printing is increasingly adopted in orthopaedic surgery.
• Its applications in hip and pelvic surgeries are expanding.
• This technology offers novel solutions for complex orthopaedic challenges.

Purpose of the Study:

• To review the primary clinical applications of 3D printing in hip and pelvic surgeries.
• To highlight the benefits of 3D printing in surgical planning, instrumentation, and implant generation.
• To discuss the potential of 3D printing in improving surgical efficiency and patient outcomes.

Main Methods:

• Review of current literature on 3D printing applications in hip and pelvic orthopaedics.
• Categorization of applications into anatomical models, patient-specific instruments (PSI), 3D-printed prostheses, and custom implants.
• Analysis of the impact of 3D printing on surgical planning, execution, and implant performance.

Main Results:

• 3D-printed anatomical models facilitate surgical planning and simulation.
• Patient-specific instruments (PSI) aid in precise bone cuts and prosthesis placement.
• Additive manufacturing enables the creation of mechanically stable, biocompatible prostheses with trabecular patterns for osseointegration.
• Custom implants offer improved fit for complex cases like massive acetabular bone loss or tumors.

Conclusions:

• 3D printing technology significantly improves surgical efficiency, reduces operation times, and lowers radiation exposure.
• It provides advanced solutions for complex hip joint diseases, enhancing treatment possibilities.
• Development of clinical guidelines is recommended to optimize the use of 3D printing for maximum patient benefit.
