Investigative Radiology
|May 10, 2018
Summary
Augmented reality (AR) guidance for lumbar facet joint injections is feasible and accurate. This innovative technique significantly reduces procedure time compared to computed tomography (CT) guidance.
Area of Science:
- Medical Imaging
- Interventional Radiology
- Surgical Technology
Background:
- Lumbar facet joint injections are common procedures.
- Accurate needle placement is crucial for efficacy and safety.
- Current guidance methods like computed tomography (CT) can be time-consuming.
Purpose of the Study:
- To evaluate the feasibility and accuracy of augmented reality (AR)-guided lumbar facet joint injections.
- To compare the performance of AR guidance with traditional CT guidance in an experimental setting.
Main Methods:
- A spine phantom with embedded markers was used.
- Two radiologists performed AR-guided and CT-guided facet joint injections.
- Needle placement accuracy and time to placement were recorded and compared.
- Image analysis by an independent radiologist assessed needle placement quality.
Main Results:
- AR-guided injections demonstrated high accuracy, with 97.5% of placements being perfect or acceptable.
- CT-guided injections achieved 100% perfect or acceptable accuracy.
- AR guidance was significantly faster, with mean times of 14 seconds versus 39 seconds (P < 0.001).
- No unsafe needle placements were observed with AR guidance.
Conclusions:
- Augmented reality guidance is a feasible and accurate method for lumbar facet joint injections in an experimental setting.
- AR guidance offers a substantial time advantage over CT guidance.
- This technology holds promise for improving efficiency and safety in interventional pain procedures.

01:16Structural Joints: Synovial Joints
7.2K
Synovial joints are the most common type of joint in the body. A key structural characteristic for a synovial joint is the presence of a joint cavity. This fluid-filled space is where the articulating surfaces of the bones contact each other. Also, unlike fibrous or cartilaginous joints, the articulating bone surfaces at a synovial joint are not directly connected to each other with fibrous connective tissue or cartilage. This gives the bones of a synovial joint the ability to move smoothly...

01:03Structural Joints: Fibrous Joints
3.9K
Fibrous joints are a type of joint where the bones are connected by fibrous connective tissue. These joints provide stability and minimal to no movement between the articulating bones. There are three types of fibrous joints.
Suture
All the bones of the skull, except for the mandible, are joined to each other by a fibrous joint called a suture. The fibrous connective tissue found at a suture strongly unites the adjacent skull bones and thus helps to protect the brain and form the face. In...

01:17Structural Joints: Cartilaginous Joints
4.2K
As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary...

Joints, also called articulations or articular surfaces, are points at which ligaments or other tissues connect adjacent bones. Joints permit movement and stability, and can be classified based on their structure or function.
Structural joint classifications are based on the material that makes up the joint as well as whether or not the joint contains a space between the bones. Joints are structurally classified as fibrous, cartilaginous, or synovial.
Fibrous Joints Are Immovable

01:30Method of Joints
1.3K
The method of joints is a commonly used technique to analyze the forces in structural trusses. The method is based on the principle of equilibrium, which assumes that the truss members are connected by frictionless pins. The forces at each joint can be determined by considering the equilibrium of the forces acting on that joint.
Since plane truss members are in the same plane, each joint is subjected to a coplanar and concurrent force system. To apply the method of joints, the first step is to...

00:58Introduction to Joints
4.9K
The adult human body usually has 206 bones, and except for the hyoid bone in the neck, each bone is connected to at least one other bone. Joints are the location where bones come together. Many joints allow for movement between the bones. At these joints, the articulating surfaces of the adjacent bones can move smoothly against each other. However, the bones of other joints may be joined by connective tissue or cartilage. These joints are designed for stability and provide little or no...
