Non-Operative Management for Minimally Displaced Periprosthetic Fractures

For elderly patients with minimally displaced periprosthetic fractures and a stable prosthesis, non-operative management with protected weight-bearing is appropriate and can achieve similar clinical and radiographic outcomes to surgery while avoiding operative risks in this vulnerable population 1.

Key Decision Points

The critical factors determining non-operative candidacy are:

  • Fracture displacement: Undisplaced or minimally displaced only
  • Prosthesis stability: Must be definitively stable (not loose)
  • Fracture pattern: Short, transverse or oblique patterns respond best 1
  • Patient factors: Low functional demand and significant comorbidities favor conservative approach

Evidence Supporting Non-Operative Management

A 2024 study of 80 elderly patients (>70 years) with periprosthetic hip fractures found that 34% were successfully managed non-operatively 1. These patients predominantly had:

  • Short, oblique, undisplaced B1 fractures
  • Significant comorbidities (88.8% of cohort)
  • Lower mortality in first 2 months compared to surgical patients (2 deaths vs 7 deaths)

The non-operative group achieved mean VAS pain scores of 2.9 points at 3 months and functional Merle D'Aubigné scores of 4.3 (pain), 4.1 (mobility), and 3.8 (ambulation) 1.

Non-Operative Protocol

Implement the following management strategy:

  • Immediate immobilization with protected weight-bearing
  • Serial radiographs at 2,4,6, and 12 weeks to monitor for displacement
  • Progressive mobilization as pain allows, typically starting with touch-down weight-bearing
  • Osteoporosis treatment to facilitate healing and prevent future fractures 2

Critical Caveats

Beware of occult prosthesis loosening: Up to 20% of apparent stable (B1) fractures actually have loose stems, which explains high failure rates with non-operative management 2. If any doubt exists about stability, surgical exploration may be warranted.

Absolute contraindications to non-operative management:

  • Any degree of prosthesis loosening (requires revision arthroplasty)
  • Displaced fractures (>2-3mm displacement or angulation)
  • Inadequate bone stock for healing
  • Long spiral or comminuted fracture patterns

When Surgery Cannot Be Avoided

If the fracture displaces during non-operative treatment or the patient fails to progress, surgical options depend on prosthesis stability:

  • Stable prosthesis (B1): Open reduction and internal fixation with locking plates 3
  • Loose prosthesis (B2/B3): Revision arthroplasty with long-stem prosthesis 2

Mortality risk is highest with revision arthroplasty and in patients with Charlson Comorbidity Index ≥6 1, making the non-operative approach particularly valuable in this high-risk subset when fracture characteristics permit.
