What is the recommended acute management of an intertrochanteric femur fracture?

Acute Management of Intertrochanteric Femur Fracture

For intertrochanteric femur fractures in older adults, surgical fixation with a cephalomedullary nail should be performed within 24-48 hours of admission, using interdisciplinary care coordination, multimodal analgesia including peripheral nerve blocks, and VTE prophylaxis. 1

Preoperative Management

Interdisciplinary Care and Timing

• Implement interdisciplinary care immediately involving orthopedics and hospitalist/orthogeriatrics teams to decrease complications and improve outcomes (strong evidence, strong recommendation). 1
• Proceed to surgery between 24-48 hours after admission (limited evidence, moderate recommendation). 1
• Do not use preoperative traction for hip fracture patients (strong evidence, strong recommendation). 1

Pain Management

• Administer multimodal analgesia including peripheral nerve block (such as iliofascial block or fascia iliaca block) in the emergency department or preoperatively (strong evidence, strong recommendation). 1
• This approach provides superior pain control compared to systemic analgesia alone and facilitates early mobilization. 1

Anesthesia Selection

• Either spinal or general anesthesia is appropriate for hip fracture patients (strong evidence, strong recommendation). 1
• The choice should be based on patient comorbidities and anesthesiologist preference, as outcomes are equivalent. 1

Surgical Management

Implant Selection Based on Fracture Pattern

For unstable intertrochanteric, subtrochanteric, and reverse obliquity fractures:

• Use cephalomedullary nail fixation (strong evidence, strong recommendation). 1
• Either short or long cephalomedullary nails may be used (limited evidence, limited strength option). 1
• Unstable patterns include comminuted fractures, those with posteromedial cortex disruption, and reverse obliquity patterns. 1, 2

For stable intertrochanteric fractures:

• While sliding hip screws were historically preferred, current evidence supports intramedullary fixation for both stable and unstable patterns. 3
• Cephalomedullary nails provide biomechanical advantages and allow earlier mobilization. 3

Intraoperative Considerations

• Administer tranexamic acid at the start of the case to reduce blood loss and transfusion requirements (strong evidence, strong recommendation). 1
• Achieve optimal fracture reduction before nail insertion, as reduction quality directly correlates with surgical success. 3
• For fractures with large posteromedial fragments, attempt internal fixation of the fragment with lag screws or cerclage wire when using any fixation method. 2
• Be aware that left-sided intertrochanteric fractures have 1.24 times higher revision rates at 1 year compared to right-sided fractures, possibly due to clockwise torque of lag screws causing nonunion. 4

Postoperative Management

Mobilization

• Allow immediate full weight bearing as tolerated after surgery (limited evidence, limited strength option). 1
• Patients typically can ambulate 2-4 days postoperatively. 5

Blood Management

• Transfuse for symptomatic anemia (moderate evidence, moderate recommendation). 1
• Use a transfusion threshold no higher than 8 g/dL in postoperative, asymptomatic hip fracture patients. 1

VTE Prophylaxis

• Use VTE prophylaxis in all hip fracture patients (moderate evidence, strong recommendation). 1
• Sequential compression devices should be used while hospitalized. 1
• Pharmacologic prophylaxis (such as enoxaparin) should be administered for 4 weeks postoperatively. 1

Bone Health

• Initiate osteoporosis evaluation and treatment during hospitalization. 1
• Draw vitamin D, calcium, and parathyroid hormone levels while hospitalized. 1
• Order outpatient DEXA scan and refer to bone health clinic. 1

Special Considerations and Pitfalls

When to Consider Arthroplasty Instead

• Hip arthroplasty may be considered for highly comminuted unstable fractures at high risk of fixation failure, particularly in patients with severe osteoporosis or concomitant hip arthritis. 6
• However, internal fixation remains the first-line treatment as it preserves the hip joint and avoids long-term prosthetic complications, with better long-term functional outcomes and mortality rates compared to arthroplasty. 6, 7

Common Complications to Monitor

• Implant cutout occurs more frequently with intramedullary nails compared to arthroplasty but less than with sliding hip screws. 8
• Malunion and coxa vara/valga are less common with cephalomedullary nails than with extramedullary fixation. 8
• Left-sided fractures require particular attention to reduction and fixation technique due to higher nonunion rates. 4
