[Conversion of anatomic to reverse shoulder arthroplasty : Does it make sense?]

Area of Science:

• Orthopedic surgery
• Biomedical engineering

Context:

• Increasing incidence of shoulder endoprostheses implantation globally.
• Rising rates of revision surgeries following primary shoulder arthroplasty.
• Reverse arthroplasty is the predominant revision procedure.

Purpose:

• To analyze revision scenarios for shoulder endoprostheses.
• To identify factors influencing surgical effort and resource consumption during revisions.
• To evaluate the benefits of specific implant designs in revision cases.

Summary:

• Revision surgeries for shoulder endoprostheses are increasing, with reverse arthroplasty being the most common approach.
• Surgical complexity and resource use vary significantly based on the primary implant and patient factors.
• Stemless primary implants within a platform system offer favorable revision pathways, enabling easier conversion to reverse arthroplasty.

Impact:

• Highlights the need for efficient revision strategies in shoulder arthroplasty.
• Suggests that implant design, particularly stemless platform systems, can significantly streamline revision procedures.
• Informs surgical planning and implant selection to optimize patient outcomes and resource allocation in revision shoulder arthroplasty.
