[Elbow prosthesis after acute fractures : Indications and technique]

Area of Science:

• Orthopedic surgery
• Biomedical engineering

Background:

• Distal humeral fractures in older adults present complex treatment challenges.
• Total elbow arthroplasty is an option for managing these fractures.

Purpose of the Study:

• To review the techniques and indications for total elbow arthroplasty in distal humeral fractures.
• To highlight factors influencing clinical outcomes in elderly patients.

Main Methods:

• Review of current literature on total elbow arthroplasty for distal humeral fractures.
• Analysis of different prosthesis designs (linked, unlinked, hemiarthroplasty).

Main Results:

• Cemented semiconstrained linked total elbow endoprosthesis is commonly used.
• Unlinked designs and hemiarthroplasty require specific conditions like intact ligaments or radial head reconstruction.
• Secondary arthroplasty is feasible after failed conservative treatment.

Conclusions:

• Total elbow arthroplasty can achieve good to very good results in older patients with distal humeral fractures.
• Individualized treatment considering fracture morphology, bone quality, and patient factors is essential.
• Weight-bearing restrictions and potential complications must be discussed preoperatively.
