The spinal surgery landscape has witnessed remarkable advancements in recent times and spinal screws are an important part of the same. Spinal screws are tiny yet powerful and play a crucial role in stabilizing the spine, correcting spine deformities, and facilitating spine fusion. 

In this blog post, we will provide an overview of the spinal screws used in spinal surgeries, explore their diverse types, and delve into their usage as a whole. 

Overview

Spinal screws are orthopedic implants, designed to affirm spinal instruments, like rods and plates to the vertebral bones. The main usage of these spine screws ranges from providing stability to the spine to curing conditions like degenerative conditions or spinal deformities. These screws typically consist of biocompatible materials like titanium or stainless steel. Such biocompatible composure of the screws ensures compatibility with the human body. 

Types of Spinal Screws 

Pedicle Screws

Pedicle screws are the most commonly used spinal screws in spinal surgeries. Spinal implants are inserted into the pedicles, the small bony protrusions on the back of each vertebra. Pedicle screws can be customized according to varying standards of the human needs. They also come in various designs, including monoaxial, polyaxial, and cannulated screws, offering a surgeon-friendly approach to surgeries. 

Laminar Screws 

Laminar screws as spine implants are inserted into the lamina. The lamina are the thin bony plates forming the vertebral arch’s posterior part. These screws are traditionally used for posterior fusion of the cervical spine and are the most common in c2 and c7 levels. 

Facet Screws 

Specifically used to stabilize the facet joints of the spine. Facet screws as a type of spine implant are typically inserted into the facet joints which are located within the vertebrae. An imminent player in spinal fusion surgery, facet screws enable the affirmed holding of the vertebrae post-surgery.

Sacral Screws

Sacral screws are essential for the fixation of the sanctum. The sanctum is the triangular bone at the base of the spine. They are typically inserted into the sanctum part to stabilize the lumbar-pelvic junction. The usage of these spine screws during spinal surgeries promotes fusion in patients who are suffering from sacroiliac joint dysfunction. Sacral screws are also important in lumbosacral fusion. 

Uses of Spine Screws

Spinal Fusion

Spine screws constitute an essential component of spinal fusion surgeries. The major objective behind the insertion of a spinal screw into the spine of a human body is to immobilize the spine and promote bone growth between adjacent vertebrae. 

Curing Spinal Deformities 

Conditions of the spine such as Scoliosis, Kyphosis, Lordosis, etc. can be corrected/cured through spine screw insertions. Spine screws provide support and stability, helping the spinal column to realign and structure the overall spinal alignment. 

Treatment of Spinal Fractures 

Spine screws are imminent stabilizers of the spine and hence can have an ardent contribution in curing spinal fractures caused by trauma or degenerative conditions. By preventing the spine from mobilizations, spine screws facilitate the overall healing of the spine.
