When an intramedullary nail is placed for a hip fracture, is it ever removed?

Intramedullary Nail Removal After Hip Fracture

Intramedullary nails placed for hip fractures are generally left in place permanently and are rarely removed unless complications arise. Unlike other orthopedic hardware, IMNs for hip fractures serve as definitive treatment and do not require routine removal after fracture healing 1.

Standard Practice: Permanent Retention

The available guidelines describe intramedullary nailing as the surgical treatment for extracapsular hip fractures (particularly subtrochanteric fractures), but make no mention of routine hardware removal 1. This is fundamentally different from fracture fixation devices in other contexts, where removal may be more common.

When Removal Does Occur

Specific Indications for Removal:

Infection is the primary reason for IMN removal. In cases of fracture-related infection (FRI):

• If the fracture has healed and infection persists, the nail should be removed as part of infection eradication 2
• Suppressive antibiotic therapy can bridge the time until bone consolidation allows safe removal 2
• The presence of an intramedullary nail makes infection harder to treat because the intramedullary canal cannot be adequately debrided with the implant in place 2

Symptomatic hardware is the second indication:

• Pain or irritation at the nail site may warrant removal 3
• One study found only 20% of femoral shaft fractures required nail removal, all for pain or irritation 3
• Patients involved in litigation had significantly higher removal rates (p=0.004), suggesting non-medical factors may influence the decision 3

Mechanical complications requiring removal include:

• Nail bending from secondary trauma 4
• Implant failure or cutout 5
• Periprosthetic fracture requiring revision surgery 5

Important Clinical Caveats

Removal Can Be Technically Challenging:

• Bent or retained nails may require specialized extraction techniques 4, 6
• If total hip arthroplasty becomes necessary later (e.g., for femoral neck fracture), the retained nail can complicate stem placement and may require partial resection rather than complete removal 6, 7

Age and Demographics:

• No significant differences in removal rates based on age, sex, BMI, or occupation have been demonstrated 3
• The elderly hip fracture population typically has limited life expectancy, making routine removal unnecessary

Bottom Line Algorithm

Leave the nail in place unless:

1. Infection develops → Remove after fracture healing + treat infection
2. Persistent pain/irritation → Consider removal only after confirming fracture union
3. Mechanical failure → Remove/revise as needed for fracture stability
4. Need for subsequent arthroplasty → Address on case-by-case basis (may require specialized extraction)

The standard of care is permanent retention, as the risks and costs of a second surgery outweigh any theoretical benefit of removal in asymptomatic patients with healed fractures.
