2.Diatal Ulna Locking Plate (Hook Type) Features

The Distal Ulna Locking Plate (Hook Type) is a specialized orthopedic implant designed for the treatment and stabilization of distal ulna fractures and related conditions. Here are the key features:


1.Hook Design:

    • The plate features hooks at the distal end, which provide additional anchorage, especially useful in securing small or complex bone fragments near the distal ulna.


2.Locking Mechanism:

    • Equipped with a locking screw system that allows the screws to lock into the plate, creating a fixed-angle construct for enhanced stability, particularly in osteoporotic or comminuted bone.


3.Anatomical Contouring:

    • The plate is pre-contoured to match the anatomy of the distal ulna, reducing the need for intraoperative bending and ensuring a better fit along the bone surface.


4.Low-Profile Design:

    • Designed to be low-profile, minimizing soft tissue irritation and reducing the likelihood of the plate being palpable or causing discomfort under the skin.


5.Multiple Screw Options:

    • Allows for various screw placement options, including locking and non-locking screws, providing flexibility in fixation based on the fracture pattern and bone quality.


6.Material Composition:

    • Typically made from biocompatible materials such as titanium or stainless steel, known for their strength, corrosion resistance, and compatibility with the human body.


7.Polished Surface:

    • The plate's surface is often polished to minimize soft tissue adhesion and reduce friction against surrounding tissues, aiding in the patient’s comfort and recovery.


8.Versatile Application:

    • Suitable for a range of distal ulna conditions, including fractures, osteotomies, nonunion or malunion corrections, and reconstructions following tumor resections or in cases of congenital deformities.


9.Radiolucent Markers:

    • Some plates may feature radiolucent markers to aid in precise placement and assessment during and after surgery via X-ray imaging.


10.Multiple Lengths and Sizes:

    • Available in various lengths and sizes to accommodate different patient anatomies and fracture types, offering tailored solutions for individual surgical needs.


These features make the Distal Ulna Locking Plate (Hook Type) a reliable and effective choice for stabilizing distal ulna fractures and addressing related orthopedic conditions.


3.Diatal Ulna Locking Plate (Hook Type) Indications


The Distal Ulna Locking Plate (Hook Type) is indicated for use in orthopedic surgeries involving the distal ulna. The key indications include:


1.Distal Ulna Fractures:

    • Used to treat fractures of the distal ulna, including transverse, oblique, comminuted, and intra-articular fractures.


2.Distal Radioulnar Joint (DRUJ) Instability:

    • Applied in cases of DRUJ instability to provide additional fixation and stability.


3.Osteotomies:

    • Indicated for corrective osteotomies (surgical bone cuts) to realign or lengthen the distal ulna.


4.Nonunion or Malunion:

    • Used in the treatment of nonunion (failure to heal) or malunion (healing in a wrong position) of distal ulna fractures, providing a stable environment for proper healing.


5.Complex Fractures:

    • Suitable for complex fractures involving multiple fragments or poor bone quality, where traditional fixation methods may be inadequate.


6.Reconstruction After Tumor Resection:

    • Used in reconstructive surgeries following the resection of bone tumors in the distal ulna.


7.Congenital Deformities:

    • Applied in surgeries to correct congenital deformities of the distal ulna.


8.Post-Traumatic Deformities:

    • Used to correct deformities resulting from previous trauma to the distal ulna, where realignment and stabilization are required.


These indications highlight the versatility of the Distal Ulna Locking Plate (Hook Type) in managing a wide range of conditions affecting the distal ulna, providing stable fixation and promoting proper healing.

7.Diatal Ulna Locking Plate (Hook Type) FAQ


1. What is a Distal Ulna Locking Plate (Hook Type)?

The Distal Ulna Locking Plate (Hook Type) is an orthopedic implant designed to treat fractures and other conditions affecting the distal ulna, which is the smaller bone on the outer side of the forearm near the wrist. The "hook type" design typically features hooks that help secure the plate to the bone, particularly in areas with complex anatomy.


2. What are the primary indications for using a Distal Ulna Locking Plate (Hook Type)?

This plate is primarily indicated for:

  • Fractures of the distal ulna, including comminuted fractures.

  • Osteotomies (surgical bone cuts) for realignment or corrective surgery.

  • Nonunion or malunion of previous ulna fractures.

  • Fixation in cases of distal radioulnar joint (DRUJ) instability.

  • Reconstruction after tumor resection or in cases of congenital deformities.


3. How does the hook design of the plate benefit fracture treatment?

The hooks on the plate provide additional fixation, particularly useful in securing small bone fragments or in areas where conventional screw fixation might be challenging. This can improve the stability of the fracture site, especially in complex fractures or osteoporotic bone.


4. What materials are Distal Ulna Locking Plates (Hook Type) made from?

These plates are generally made from biocompatible materials such as titanium or stainless steel. Titanium is often preferred for its strength, light weight, and lower risk of causing allergic reactions.


5. Is the Distal Ulna Locking Plate (Hook Type) anatomically contoured?

Yes, these plates are typically pre-contoured to match the anatomy of the distal ulna, which helps in minimizing the need for intraoperative bending and ensures a better fit on the bone.


6. What are the benefits of the locking mechanism in this plate?

The locking mechanism allows the screws to lock into the plate, creating a fixed-angle construct. This provides enhanced stability, especially in osteoporotic bone or in fractures with poor bone quality, and helps maintain alignment during the healing process.


7. Can this plate be used in pediatric patients?

The use of this plate in pediatric patients is possible but depends on the specific case. Careful consideration is needed as pediatric bones are still growing, and the implant should not interfere with the growth plate or cause growth disturbances.


8. How is the plate fixed to the bone?

The plate is fixed to the bone using locking screws that are inserted through the plate and into the bone. The hooks provide additional anchorage, particularly in areas with complex anatomy or where additional fixation is needed.


9. What are the potential complications associated with the use of this plate?

Possible complications can include infection, allergic reactions to the implant material, hardware irritation, nonunion or malunion of the fracture, and the need for hardware removal if it causes discomfort or interferes with soft tissues.


10. Is the Distal Ulna Locking Plate (Hook Type) visible or palpable under the skin?

Due to its low-profile design, the plate is intended to minimize soft tissue irritation and is typically not easily visible or palpable under the skin. However, in thinner patients or depending on the implant’s placement, it may be felt.


11. How long does the plate stay in the body?

The plate is usually left in the body permanently unless it causes complications or discomfort. In some cases, the plate may be removed after the bone has fully healed, based on the surgeon's evaluation.


12. Can the Distal Ulna Locking Plate (Hook Type) be used in emergency trauma surgery?

Yes, this plate is suitable for use in emergency trauma surgery, particularly in complex fractures of the distal ulna that require stable and precise fixation.


13. What should a patient expect during recovery?

Recovery involves immobilization of the affected area initially, followed by gradual physical therapy to restore movement and strength. The timeline for recovery varies depending on the severity of the fracture, the patient's overall health, and adherence to post-operative care instructions.


14. Is this plate compatible with other fixation devices?

The Distal Ulna Locking Plate (Hook Type) can be used alongside other fixation devices depending on the fracture type and surgical plan. Compatibility with other implants or screws should be assessed by the surgeon.


15. What is the expected outcome after using this plate?

The expected outcome is a stable, well-aligned fracture that heals correctly with restored function of the forearm and wrist. Long-term outcomes depend on factors like the patient’s age, bone quality, and adherence to rehabilitation protocols.
