The intervertebral foramen is crucial in spinal anatomy, acting as a conduit for spinal nerves and blood vessels. For clinicians, a solid understanding of its anatomy and pathology is vital, particularly in surgical settings. This article explores valuable insights regarding surgical trephines associated with the intervertebral foramen, presenting statistics and essential data to enhance your understanding of this subject.
This anatomical structure sits between two adjacent vertebrae, facilitating the exit and entry of spinal nerves. According to the National Center for Biotechnology Information (NCBI), the human body consists of approximately 31 pairs of spinal nerves that pass through the intervertebral foramina.
Studies show that the average width of the foramen in adults typically varies between 6 to 10 mm. A systematic review published in the Journal of Orthopaedic & Sports Physical Therapy highlights that changes in foraminal size can significantly impact the likelihood of nerve impingement.
As individuals age, the intervertebral foramen undergoes notable changes. Research featured in the Journal of Spinal Disorders & Techniques indicates that the size of the foramen may decrease by up to 20% in people over the age of 60, which raises the risk for foraminal stenosis and nerve compression.
Surgical trephines have increasingly gained traction in various spinal procedures, particularly in addressing intervertebral foramen-related issues. A study published in the Spine Journal revealed that the application of surgical trephines has resulted in a success rate nearing 80% in relieving symptoms associated with foraminal stenosis.

Research published in the World Neurosurgery demonstrates that decompression via trephines resulted in statistically significant improvements in postoperative outcomes, including an 83% reduction in pain scores.
While surgical procedures can yield positive outcomes, they carry inherent risks. The same study from *World Neurosurgery* noted that complications from trephine use arise in roughly 5-10% of cases, with infections and nerve injuries being the most frequently reported complications.
Demographic factors play a critical role in assessing outcomes from surgical interventions. Research published in *The Spine Journal* indicates that individuals aged between 40-60 comprise the largest demographic undergoing surgeries related to the intervertebral foramen, accounting for about 60% of all cases. Moreover, approximately 65% of these patients report satisfactory long-term results post-surgery.
Grasping the anatomy of the intervertebral foramen and the use of surgical trephines is essential for effective clinical application. As surgical methods evolve, accessing accurate and current statistics will assist both patients and clinicians in making informed choices. Such insights are valuable in navigating the complexities of spinal surgeries and underscore the necessity for ongoing research in this critical anatomical area.
