The orthopedic bone screw is one of the commonly used trauma implants that are used for the fixation of fractured bone fragments. The shape & design of these screws is similar to the screws that are used in other industries. The mechanical principle of all screws is the same but the role depends on where they are being used.

In this post, we will have a look at what orthopedic screws are and why they are used. To get an international standard quality range of medical screws and other orthopedic devices, find experienced orthopedic instruments manufacturers.

What Are Orthopedic Screws?

Bone screws are the most used orthopedic devices. They are often applied with other orthopedic implants like trauma plates. These screws are available in different sizes and head configurations. They are selected depending on the location and severity of the condition. Here are the common uses of orthopedic screws:

• Fixing implants to the bone
• Bone-to-bone fixation
• Fixing soft tissue to bone
  

What Are the Components of a Screw?

An orthopedic screw has three components:

• The head
• The shaft
• The tip
  

Head

Head has two primary functions:

Prevents the screw to sink completely into the bone. In some cases, a washer is applied to make the head bigger and distribute the load evenly.

Provides a slot for the screwdriver to fit and apply torque effectively during the application. Different types of screw heads (star drive and hex drive) are available.

Shaft

The shaft is the long part of the orthopedic screw which is present between the head and the tip. Orthopedic screws are available with a fully and partially threaded shafts.

Tip

The tip is the pointed end of the screw that helps drill thread into the bone during the application.

How Does Orthopedic Screws Work?

Screws contain threads and when the torque is applied during their application, they produce a linear motion. During the application, the screws are turned through a stationary object from their head. As a result, their threads grip the bone firmly while providing the much-needed fixation.

Which Instruments Are used for Screw Insertion?

Here are some of the instruments that may be used for the application of screws:

• Drill Bits
• Drill Guide
• Taps
• Depth Gauges
• Screwdrivers
