Hip prostheses in young adults. Surface prostheses and short-stem prostheses

Area of Science:

• Orthopaedic Surgery
• Biomedical Engineering
• Materials Science

Background:

• Conventional hip prostheses show poor outcomes in young, active patients.
• Younger patients require implants that can withstand higher activity levels.
• Advancements in information technology favor non-cemented hip implants.

Purpose of the Study:

• To explore less invasive hip implant options for young adults.
• To address the challenges of implant survival in active young patients.
• To compare the suitability of hip resurfacing and short stem prostheses.

Main Methods:

• Review of research on hip resurfacing and short stem prostheses.
• Analysis of implant design focusing on metaphyseal and diaphyseal bone use.
• Evaluation of revision surgery complexity for different implant types.

Main Results:

• Hip resurfacing has resurged as a less invasive alternative.
• Short stem prostheses utilize metaphyseal bone more than diaphyseal bone.
• Both hip resurfacing and short stem prostheses are indicated for young adults.

Conclusions:

• Hip resurfacing offers simpler revision surgery compared to short stems.
• Preserving bone and soft tissues are key goals for young hip replacement patients.
• Optimizing implant stability and longevity in active young patients remains a priority.
