Pelvic fractures in older adults are increasingly common fragility fractures, often occurring from a sideways fall onto the hip or pelvis. The most common fragility pelvic fractures are pubic ramus fractures (superior and inferior rami of the pubis), sacral insufficiency fractures, and iliac wing fractures. Unlike high-energy pelvic ring fractures from road traffic accidents (which may require surgical fixation), fragility pelvic fractures in older adults are usually treated conservatively with weight-bearing as tolerated and a walking aid. The walking cane plays a critical role in this management.
Types of Fragility Pelvic Fracture and Cane Use
| Fracture Type | Stability | Weight-Bearing and Cane Protocol |
|---|---|---|
| Isolated pubic ramus fracture | Stable (posterior ring intact) | Weight-bearing as tolerated immediately; cane or walking frame for pain; typically 4-8 weeks |
| Bilateral pubic rami (butterfly) fracture | Unstable if posterior ring also involved | Assess posterior ring; if stable posterior ring: WB as tolerated with cane; if unstable: orthopedic input |
| Sacral insufficiency fracture | Usually stable | Weight-bearing as tolerated; cane for 6-12 weeks; pain often severe initially |
| Iliac wing fracture | Usually stable | Weight-bearing as tolerated with cane; abductor weakness if iliac crest involved |
| High-energy pelvic ring fracture | Variable; often unstable | Surgical fixation often needed; cane after fixation per orthopaedic protocol |
Cane vs Walking Frame for Pelvic Fractures
For older adults with fragility pelvic fractures, a walking frame (Zimmer frame) is often preferable to a single walking cane in the acute phase because:
- Bilateral upper limb support reduces the asymmetric loading that a single cane creates
- Pelvic fracture pain is often bilateral (pubic symphysis and sacral fractures cause midline pain) -- bilateral support is more effective
- Older adults with pelvic fractures often have reduced bone density and multiple comorbidities making single-cane use less safe
A walking cane becomes appropriate as pain reduces and confidence returns, typically at 4-6 weeks for isolated ramus fractures.
Sacral Insufficiency Fracture: Specific Considerations
Sacral insufficiency fractures are often missed on plain X-ray (detected on MRI or bone scan). They cause severe sacral pain radiating to both buttocks, often worse sitting than standing. The pain can be disabling for weeks. A walking cane or frame is essential. Sacral fractures heal slowly (8-12 weeks for significant pain reduction). Vertebroplasty/sacroplasty (cement injection) is an option for refractory pain.
