Herniated Intervertebral Disc l: Introduction01:29

Herniated Intervertebral Disc l: Introduction

Intervertebral disc herniation refers to the displacement of the nucleus pulposus (the gel-like inner core of the disc) through a tear or weakened area in the annulus fibrosus (the outer fibrous ring). The displaced disc material extends beyond the normal boundaries of the disc space and may compress or irritate nearby spinal nerve roots or, less commonly, the spinal cord.Etiology and Risk FactorsHerniation commonly results from degeneration, in which aging reduces disc hydration and...
Spinal Nerves: Plexus II01:21

Spinal Nerves: Plexus II

The plexuses of the lower body include the lumbar, sacral, and coccygeal plexuses, which innervate the abdomen, pelvis, legs, and coccygeal region. These plexuses control the transmission of sensory information and coordinate motor functions of the lower body.
The Lumbar Plexus
The lumbar plexus is situated within the lumbar region of the back and is primarily formed by the first four lumbar spinal nerves (L1 to L4). This plexus extends its branches into several nerves, including the...
Abdominal Regions and Quadrants01:19

Abdominal Regions and Quadrants

To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four quadrants...
Spinal Nerves: Anatomy01:23

Spinal Nerves: Anatomy

Spinal nerves are pivotal conduits in the nervous system, bridging the central nervous system (CNS) with the peripheral nervous system (PNS). These nerves enable a complex communication network between the brain, spinal cord, and the rest of the body, facilitating sensory input, motor output, and autonomic functions.
There are 31 bilateral pairs of spinal nerves, each emerging from the spinal cord through the intervertebral foramina—openings between adjacent vertebrae. These nerves are...
Appendicitis-I: Introduction01:22

Appendicitis-I: Introduction

The appendix, a small, narrow, blind tube extending from the inferior part of the cecum, is widely regarded as a vestigial organ, having lost much of its original function through evolution. Despite its diminished role, the appendix can become inflamed, a condition known as appendicitis.
Etiology: Appendicitis can arise from various causes, primarily rooted in the obstruction of the appendix lumen. Factors contributing to this obstruction include fecal accumulation, lymphoid hyperplasia and, in...
Degenerative Disc Disease ll: Pathophysiology01:23

Degenerative Disc Disease ll: Pathophysiology

The symptoms of degenerative disc disease arise from a combination of mechanical compression, vascular compromise, and biochemical inflammation, which together disrupt nerve function and produce pain.Mechanical CompressionDisc degeneration reduces height and elasticity, predisposing to herniation of the nucleus pulposus, a major cause of radicular pain. Herniations may be protrusion (bulging with intact annulus), extrusion (nucleus extends beyond disc but remains connected), or sequestration...

Summary

Sacroiliac joint disease can cause sciatica-like pain. Injecting medication into the sacroiliac joints provided relief for patients with pseudosciatica, confirming this as a potential pain source.

Area of Science:

  • Rheumatology
  • Pain Medicine
  • Diagnostic Imaging

Background:

  • Sacroiliac joint (SIJ) disease is frequently overlooked as a cause of sciatica-like pain.
  • Sciatica-like symptoms often lead to extensive lumbar spine investigations, potentially missing the SIJ as the pain generator.

Purpose of the Study:

  • To evaluate the efficacy of intra-articular sacroiliac joint injections in patients with sciatica-like pain.
  • To describe a reproducible fluoroscopic technique for SIJ medication instillation.

Main Methods:

  • A 14-year retrospective study of 133 patients with sciatica-like pain and normal lumbar spine imaging (myelogram or MRI).
  • Fluoroscopically guided intra-articular injection of lidocaine and triamcinolone acetonide into the sacroiliac joints.
  • Documentation of pain relief and its duration post-injection.

Main Results:

  • Correctly placed sacroiliac joint injections provided pain relief in patients diagnosed with pseudosciatica.
  • The duration of pain relief varied significantly among patients.
  • The study confirmed sacroiliac joints as a potential source of sciatic-like pain.

Conclusions:

  • Sacroiliac joint disease should be considered in the differential diagnosis of sciatica-like pain.
  • Fluoroscopically guided SIJ injections are a viable treatment option for select patients.
  • Further research into SIJ pain mechanisms and treatment optimization is warranted.
