Periprosthetic Fracture Management - Vancouver B2/B3 Hip

intermediate Level

Primary Indication

Periprosthetic femoral fracture around well-fixed (B1) or loose (B2/B3) stem

Danger Structures

  • Sciatic nerve - 15-30mm posterior to hip joint depending on approach and position, injury causes foot drop and sensory loss - EXAM KEY: identify and protect, keep hip flexed to relax nerve
  • Femoral neurovascular bundle - 30-50mm medial to anterior hip joint, injury catastrophic - EXAM KEY: stay on bone with anterior retractors
  • Superior gluteal neurovascular bundle - 30-50mm proximal to greater trochanter, injury causes abductor weakness - EXAM KEY: avoid proximal dissection, stay in safe zone
  • Lateral femoral cutaneous nerve - variable position 20-50mm from anterior incisions, injury causes meralgia paresthetica - EXAM KEY: protect when visible
  • Medial femoral circumflex artery - main blood supply to femoral head, at risk during capsulotomy - EXAM KEY: careful dissection around posterior femoral neck

Perform intraoperative imaging/fluoroscopy to confirm adequate position and alignment

Surgeon's Tip
EXAM KEY: Documentation of intraoperative findings is crucial for Periprosthetic Fracture Management - Vancouver B2/B3 Hip.
Danger Zone
  • Radiation exposure
  • Inadequate imaging
