The intervertebral foramen plays a critical role in spinal anatomy, serving as the passageway for spinal nerves and blood vessels. Understanding its anatomy and pathology is essential for clinicians, particularly in the realm of surgical interventions. This article delves into surgical trephines' insights related to the intervertebral foramen, providing relevant statistics and essential data that will enhance your knowledge on this topic.
The intervertebral foramen is located between two adjacent vertebrae and is responsible for the exit and entry of spinal nerves. According to the National Center for Biotechnology Information (NCBI), there is an estimated 31 pairs of spinal nerves in the human body that utilize the intervertebral foramina.
Research indicates that the average foramen width ranges from 6 to 10 mm in adults. A systematic review published in the Journal of Orthopaedic & Sports Physical Therapy found that variations in the foraminal size can significantly influence the risk of nerve impingement.
With age, the intervertebral foramen can change significantly. A study published in the Journal of Spinal Disorders & Techniques suggested that the size of the foramen decreases by up to 20% in individuals over 60, leading to an increased likelihood of foraminal stenosis and nerve compression.
Surgical trephines have been increasingly utilized in various spinal surgeries, especially when addressing issues related to the intervertebral foramen. A study published in the Spine Journal reported that utilizing surgical trephines can lead to a nearly 80% success rate in alleviating symptoms from foraminal stenosis.

While surgical interventions can be effective, they are not without risks. The same *World Neurosurgery* study noted that complications related to the use of trephines occur in approximately 5-10% of cases, with infections and nerve injuries being the most common issues reported.
It is essential to consider demographic factors when reviewing surgical intervention outcomes. Research published in *The Spine Journal* indicated that patients aged 40-60 are the most common demographic undergoing surgeries involving the intervertebral foramen, constituting about 60% of total cases. Furthermore, about 65% of these patients report satisfactory long-term results after surgery.
Understanding the intervertebral foramen's anatomy and the application of surgical trephines is imperative for effective clinical practice. As surgical techniques continue to evolve, ensuring access to accurate and up-to-date statistics will aid in informed decision-making for both patients and clinicians. These insights can aid in navigating the complex nature of spinal surgeries and highlight the need for continued research in this critical area of anatomy.
