Orthopedic Surgery: Exploring the World of Proximal Humeral Plate

What type of screws can be used in the distal holes of 3.5 PHP?

1) Self-tapping screws 2) Cortical screws 3) Cancellous screws 4) Locking screws

Answer:

In orthopedic surgery, self-tapping screws, cortical screws, and locking screws can be utilized in the distal holes of a 3.5mm Proximal Humeral Plate.

Have you ever wondered about the fascinating world of orthopedic surgery? Let's journey into the realm of Proximal Humeral Plates (PHP). These medical devices play a crucial role in fixing fractures and providing stability to the humerus bone.

When it comes to the distal holes of a 3.5mm PHP, various types of screws can be used depending on the specific requirements of the surgery. Self-tapping screws are designed with cutting flutes at the tip to tap their own threads, making them ideal for easier insertion.

Cortical screws, on the other hand, are suitable for use in the hard, dense outer layer of bone known as cortical bone. These screws provide strong fixation in areas with denser bone quality, ensuring stability and support.

Locking screws offer a unique advantage by mechanically engaging with the plate to form a fixed-angle construct, enhancing stability and fixation. In the context of a 3.5mm PHP, locking screws can be utilized in the distal holes to provide added strength and support.

Therefore, the choice of screws for a 3.5mm Proximal Humeral Plate depends on factors such as the plate's design and the quality of the bone where it will be implanted. Each type of screw serves a specific purpose in ensuring the successful fixation of fractures and promoting bone healing.
