Revision hip arthroplasty in nonagenarians

Area of Science:

• Orthopedic Surgery
• Geriatric Medicine
• Reconstructive Surgery

Background:

• Revision hip arthroplasty is a complex procedure.
• Nonagenarians represent a rapidly growing, yet surgically vulnerable, elderly population.
• Outcomes data for revision hip arthroplasty in this extreme age group are limited.

Purpose of the Study:

• To present the outcomes of revision hip arthroplasties performed in nonagenarians.
• To identify surgical indications, perioperative factors, and postoperative outcomes.
• To assess complication rates and mortality in this specific patient cohort.

Main Methods:

• Prospective data collection over an 8-year period at a single institution.
• Inclusion of 15 nonagenarian patients undergoing revision hip arthroplasty (14 single-stage, 1 two-stage).
• Recording of surgical indications, ASA grade, comorbidities, complications, transfusion needs, length of stay, and discharge disposition.

Main Results:

• Mean patient age was 92 years (ASA grade 2).
• High complication rate (63%) and blood transfusion requirement (75%).
• Mortality rates: 7% at 30 days, 20% at 1 year, and 33% at 3 years.

Conclusions:

• Revision hip arthroplasty can be considered in nonagenarians when indicated.
• Expectation of significantly higher complication and transfusion rates in this elderly population.
• Careful patient selection and perioperative management are crucial for successful outcomes.
