Purpose and Function:
Locking bone plates are designed to address specific challenges associated with conventional bone plates, especially in fractures involving poor bone quality or comminuted fractures.
The primary function of locking plates is to provide a stable platform for fracture fixation by accommodating locking screws, which engage directly with the plate to create a fixed-angle construct.
Construction and Design:
Locking bone plates have specialized holes along their length to accept locking screws. These holes allow for a fixed-angle connection, providing increased stability.
The plate itself is typically contoured to match the anatomy of the bone, ensuring a proper fit and minimizing the risk of soft tissue irritation.
Locking Mechanism:
Locking plates use locking screws that engage with the plate in a threaded fashion, creating a stable and fixed-angle connection. This locking mechanism helps prevent screw loosening and enhances the overall stability of the construct.
Material:
Similar to traditional bone plates, locking bone plates are commonly made from biocompatible materials such as titanium or stainless steel. These materials provide strength, durability, and corrosion resistance.
Indications:
Locking bone plates are often indicated in cases where traditional plates may not offer sufficient stability, such as fractures in osteoporotic bones, periarticular fractures, or situations requiring a fixed-angle construct.
Surgical Technique:
The surgical technique for using locking bone plates involves precise placement of the plate on the bone, aligning it with the fracture site. Locking screws are then inserted through the plate and engage with the bone, creating a secure and stable fixation.
Applications:
Locking bone plates find applications in various orthopedic surgeries, including long bone fractures, periarticular fractures, corrective osteotomies, and cases where a high degree of stability is required for successful bone healing.
Postoperative Care:
After the surgical placement of locking bone plates and screws, patients may undergo rehabilitation and physical therapy to restore mobility and strength. Regular follow-up appointments monitor the healing process and the stability of the fixation.
