Plaque de verrouillage humérale distale médiale

Q&UN

T1: What is the Medial Distal Humeral Locking Plate used for?
A1: It is designed for fixation of distal humerus fractures, specifically those involving the medial column or intra-articular extension.

T2: 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.

T3: 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.

T4: Can the Medial Column Locking Plate be used alone?
A4: 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?
A5: 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?
A6: 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: Oui, the locking mechanism provides secure fixation even in osteoporotic bone, reducing the risk of loosening or failure.

Q8: What surgical approaches are commonly used for this plate?
A8: The plate is typically applied through a medial approach to the distal humerus, providing direct visualization of the fracture site.

Q9: 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.
