Locking Plate

Definition

A locking plate is a type of orthopedic implant used in surgical procedures to stabilize fractured bones. It features threaded holes that allow screws to lock into the plate, creating a fixed-angle construct. This design provides enhanced stability by reducing the risk of screw loosening and allows the plate to function as an internal fixator.

Relevance to the MedTech Industry

Locking plates play a critical role in fracture management, particularly for complex or osteoporotic fractures. They improve patient outcomes by enabling stable fixation, early mobilization, and optimal bone healing, especially in anatomically challenging regions.

Challenges or Considerations

  • Patient-Specific NeedsThe size, shape, and material of the plate must be tailored to the patient's anatomy and fracture type.

  • Osteoporotic BoneLocking plates are particularly beneficial for patients with weak or brittle bones, but their performance must be validated for these conditions.

  • Infection RiskAs with any implant, maintaining sterility during implantation and preventing post-operative infections are critical.

  • Material SelectionCommon materials include stainless steel and titanium, chosen for their biocompatibility and mechanical properties.

  • Surgeon TrainingProper placement and technique are essential to maximize the benefits of locking plates and minimize complications.

Examples of Applications

  1. Proximal Humerus Fractures: Stabilization of fractures in the shoulder region.

  2. Distal Radius Fractures: Commonly used for wrist fractures requiring precise alignment.

  3. Pelvic Fractures: Provides robust fixation for complex pelvic injuries.

  4. Femoral and Tibial Fractures: Used in long bone fractures to enhance stability and healing.

  5. Osteoporotic Fractures: Provides secure fixation in patients with compromised bone density.

Key Features of Locking Plates

  • Fixed-Angle Stability: Reduces micromotion and enhances mechanical strength.

  • Anatomically Contoured Design: Matches the shape of specific bones for precise fitting.

  • Threaded Screw Holes: Locks screws to the plate, minimizing loosening and enhancing stability.

  • Minimally Invasive Options: Some systems allow for percutaneous placement, reducing surgical trauma.

  • Radiolucency: Ensures compatibility with imaging for accurate fracture reduction and fixation.

Related Terms

  • Open Reduction Internal Fixation (ORIF): A surgical procedure where locking plates are commonly used to stabilize fractures.

  • Cortical Screws: Screws used to fix plates to bone, often used with locking plates for hybrid fixation.

  • Osteosynthesis: The surgical connection of bone fragments using devices like locking plates.

  • Titanium Implants: A common material for locking plates due to its strength and biocompatibility.

  • Biomechanics: The study of mechanical principles applied to the human body, critical in designing locking plates.
