Medial Distal Humeral Locking Plate
q&នៃក
សំណួរទី 1: What is the Medial Distal Humeral Locking Plate used for?
ក 1: It is designed for fixation of distal humerus fractures, specifically those involving the medial column or intra-articular extension.
សំណួរទី 2: Why is a medial plate necessary in distal humerus fixation?
A2: The medial plate provides strong buttress support and prevents varus collapse, ensuring stable fixation of the medial column.
សំណួរទី 3: What is the typical material of the Distal Humerus Medial Plate?
A3: It is made from high-strength titanium alloy (Ti-6AL-4V) or stainless steel for optimal biocompatibility and durability.
សំណួរទី 4: Can the Medial Column Locking Plate be used alone?
ក 4: It can be used alone in simple medial fractures but is often combined with a lateral plate in bicolumn fixation for complex distal humerus fractures.
q5: How is the plate anatomically contoured?
ក 5: The plate is pre-shaped to match the natural curvature of the distal humerus’ medial aspect, minimizing the need for intraoperative bending.
q6: What types of screws are used with the Medial Distal Humeral Locking Plate?
ក 6: It uses a combination of locking head screws for angular stability and cortical screws for compression and initial fixation.
q7: Is this plate suitable for osteoporotic bone?
A7: បាត, the locking mechanism provides secure fixation even in osteoporotic bone, reducing the risk of loosening or failure.
សំណួរទី 8: What surgical approaches are commonly used for this plate?
ក 8: The plate is typically applied through a medial approach to the distal humerus, providing direct visualization of the fracture site.
សំណួរទី 9: What plate sizes are available?
A9: It is available in various lengths (typically 4–10 holes) and both left and right anatomical versions to match patient anatomy.
Q10: What are potential complications after fixation?
A10: Possible issues include screw irritation, joint stiffness, or ulnar nerve irritation, but proper placement and technique minimize these risks.
