Surgical Management: Arthroplasty for Femoral Neck Fracture

A 70-year-old female with a femoral neck fracture should undergo arthroplasty (not internal fixation), with the specific choice between hemiarthroplasty and total hip arthroplasty (THA) determined by her pre-fracture mobility, cognitive status, and activity level—if she was independently mobile and cognitively intact, THA is preferred; if she has significant cognitive impairment or limited mobility, hemiarthroplasty is appropriate. 1

Immediate Surgical Planning

Timing of Surgery

  • Operate within 24-48 hours of admission to decrease complications and improve outcomes 1
  • Surgery should not be delayed beyond 48 hours unless absolutely necessary for medical optimization
  • After-hours surgery is acceptable only with experienced teams and adequate resources; otherwise, postpone to daytime for optimal conditions 2

Arthroplasty vs Internal Fixation Decision

At age 70, arthroplasty is strongly recommended over internal fixation because:

  • Internal fixation carries high risks of avascular necrosis and nonunion in this age group
  • Arthroplasty provides immediate stability and allows early weight-bearing 1
  • The displaced nature of most femoral neck fractures in elderly patients makes fixation unreliable 3

Choosing Between Hemiarthroplasty and Total Hip Arthroplasty

Key Patient Assessment Factors

Evaluate these specific characteristics:

Favor THA if:

  • Independently mobile before fracture (walks without assistive devices at home)
  • Cognitively intact (no dementia or significant cognitive decline)
  • Active lifestyle with high functional demands
  • Age closer to 65-75 years
  • No pre-existing hip arthritis 3, 4

Favor Hemiarthroplasty if:

  • Cognitive impairment (Alzheimer's, dementia)
  • Limited pre-fracture mobility (dependent on walker/wheelchair)
  • Multiple comorbidities suggesting frailty (CHF, CKD, COPD, Parkinson's)
  • Age >80 years
  • Poor baseline functional status 1, 4

Evidence Nuance

While guidelines suggest THA for healthier patients, recent high-level evidence does not consistently demonstrate clinical superiority of THA over hemiarthroplasty even in selected higher-functioning patients 2. However, THA may provide better long-term functional outcomes in appropriately selected patients 5. The 2022 AAOS guidelines give a strong recommendation for arthroplasty in displaced femoral neck fractures but only moderate recommendation regarding THA versus hemiarthroplasty choice 1.

Technical Surgical Specifications

Cementation

Use cemented femoral stems (strong recommendation, strong evidence) 1, 6

  • Cementless fixation substantially increases periprosthetic fracture risk in elderly patients 2
  • This is a critical technical point that directly impacts mortality and morbidity

Hemiarthroplasty Type (if chosen)

Either unipolar or bipolar hemiarthroplasty is acceptable (moderate recommendation) 1

  • Recent network meta-analysis shows bipolar may have slight advantages in dislocation rates and blood loss, but differences are not statistically significant 5

Surgical Approach

No preferred approach (anterolateral, posterior, or direct anterior all acceptable) 1

  • Choose based on surgeon experience and comfort

Anesthesia

Either spinal or general anesthesia is appropriate (strong recommendation) 1

Perioperative Management

Tranexamic Acid

Administer TXA at start of case to reduce blood loss and transfusion requirements (strong recommendation, strong evidence) 1, 6

Interdisciplinary Care

Involve orthogeriatric/hospitalist team for medical optimization and perioperative management (strong recommendation, strong evidence) 1

  • This significantly decreases complications and improves outcomes
  • Should include assessment for delirium risk, pneumonia prevention, and renal protection

Postoperative Mobilization

Allow immediate full weight-bearing to enable early mobilization and prevent surgery-related complications 7

Common Pitfalls to Avoid

  1. Delaying surgery beyond 48 hours without compelling medical reasons—increases mortality
  2. Using cementless stems—dramatically increases periprosthetic fracture risk in this population
  3. Choosing internal fixation in a 70-year-old—high failure rate with avascular necrosis and nonunion
  4. Performing THA in cognitively impaired patients—increased dislocation risk without functional benefit
  5. Operating without orthogeriatric consultation—misses opportunity to optimize medical management
