Orthopedic Board Prep: Intramedullary Nailing MCQs & Surgical Concepts
Key Takeaway
For a hemodynamically stable patient with a comminuted mid-shaft femoral fracture, immediate reamed intramedullary nailing is generally the preferred surgical approach. Reaming optimizes the medullary canal for a larger nail, enhancing bending and torsional stiffness. This method ensures superior biomechanical stability and promotes higher rates of fracture union, crucial for optimal recovery.
A 65-year-old female presents following a fall. She is unable to weight-bear. The following radiograph is obtained. Describe your findings and outline the management plan.
Candidate: "This is an anteroposterior radiograph showing a displaced, comminuted intertrochanteric fracture of the right proximal femur. My management would include stabilization, optimization of medical comorbidities, and surgical fixation, most likely with a cephalomedullary nail."
Failing to classify the fracture (e.g., AO/OTA 31-A), neglecting the "Tip-Apex Distance" concept, or jumping to surgery without discussing the crucial preoperative medical optimization of the elderly patient. Candidates often forget to mention assessing for dynamic versus static locking.
Systematically address: 1. Assessment: "This is an AO/OTA 31-A2.2 unstable intertrochanteric fracture. I note comminution of the posteromedial cortex." 2. Optimization: "I would initiate a standard geriatric hip fracture pathway (e.g., NHFD guidelines), ensuring prompt analgesia, fluid resuscitation, and medical review (cardiac/thromboprophylaxis)." 3. Surgical Plan: "Given the instability, a long cephalomedullary nail is preferred. I would emphasize achieving a Tip-Apex Distance (TAD) of less than 25mm to minimize cut-out risk and ensure the screw is placed centrally/inferiorly in the head." 4. Considerations: "I would discuss the importance of anatomical reduction of the medial cortical buttress to prevent varus collapse."
