Updated Blocking Techniques for Lower Extremity Medullary Nailing: Beyond the Concavity of Deformity.

Modern blocking techniques are useful to achieve anatomic alignment and stable fixation during end-segment nailing. Whether with screws or drill bits, blocking implants can correct both angular and translational deformities. Understanding the biomechanics of blocking implants allows the surgeon to properly plan their placement based on principles rather than dogma. We use case examples to highlight updates in blocking techniques during acute surgical fixation and chronic deformity correction.
