Terminology Clarification
Yes, "slipped disc" and "prolapsed intervertebral disc" are the same condition—both terms refer to herniation of the nucleus pulposus through the fibrous outer covering of an intervertebral disc. 1
Understanding the Terminology
The medical literature uses these terms interchangeably to describe the same pathological process:
Herniated disc is the formal medical term defined as "herniation of the nucleus pulposus of an intervertebral disc through its fibrous outer covering, which can result in compression of adjacent nerve roots or other structures." 1
"Slipped disc" is the lay term commonly used by patients and non-specialists to describe this same condition. 1
Prolapsed intervertebral disc is another formal medical term used synonymously with herniated disc in clinical practice and research literature. 2, 3
Spectrum of Disc Pathology
The literature describes various degrees of disc displacement, all falling under the umbrella of disc herniation:
Bulge, protrusion, prolapse, extension, extrusion, or sequestration all represent different radiologic manifestations or severity levels of disc herniation. 4
These terms describe the extent and configuration of disc material displacement but all refer to the same underlying pathological process. 4
Clinical Implications
The key clinical point is that the terminology used (whether "slipped," "prolapsed," or "herniated") does not change the diagnostic approach or management. 1
The natural history of lumbar disc herniation with radiculopathy shows improvement within the first 4 weeks with noninvasive management in most patients. 1
Treatment decisions should be based on clinical presentation (presence of radiculopathy, neurologic deficits, or red flags like cauda equina syndrome) rather than the specific terminology used. 1
