What is the primary function of a meniscal probe/Dandy nerve hook?

The primary function of a meniscal probe, also known as a Dandy nerve hook, is to check for meniscal tears in joints. This instrument is specifically designed for exploring the joint space, allowing the veterinarian to assess the integrity of the meniscus—specifically, a C-shaped cartilage structure that cushions the knee joint and helps in its stability and movement.

When using this probe, the veterinarian can manipulate the joint and apply pressure, which allows for the detection of any tears or irregularities within the meniscus. This assessment is crucial in diagnosing conditions like meniscal injuries, which can lead to pain and decreased mobility in animals.

The other options provided do not accurately represent the primary function of this tool. While elevating tissue away from bones and measuring curvature might be relevant for other instruments, they do not align with the unique purpose of the meniscal probe. Similarly, cutting through wire safely is not related to the investigative nature of a probe or hook designed for examining soft tissue and cartilage within joints.
