ExsoMed Case Study: Use of the InFrame Intramedullary Threaded Micro Nail for an Oblique Comminuted Fracture of the 3rd Proximal Phalanx

Nathan Lesley, MD, The Hand to Shoulder Center of Fort Worth Fort Worth, TX. Case Presentation: Patient was a 33-year-old male who suffered a midshaft oblique fracture with comminution to his 3rd proximal phalanx from a crush injury. An operative solution that achieved rotational stability and early range of motion (ROM) was desired due to the unstable fracture pattern and need to return to work quickly. Pre-op Plan: Dr. Lesley typically considers lag screw fixation for oblique fracture patterns but wanted to achieve early ROM without complications such as stiffness. A minimally invasive approach using K-wires was an option but too often result in poor fixation, require a long period of immobilization, and have high infection rates. Dr. Lesley chose InFrame because the cannulated, fully threaded micro nail has a 2.0mm diameter design that allows cross implantation constructs to achieve rigid fixation, rotational stability, and early ROM. The innovative guidewire removes the need for reaming and simplifies implant placement, resulting in accuracy and reduced surgical time. Biomechanical testing has demonstrated the superior rigidity with InFrame compared to other modalities.
