A foraminal disc herniation occurs when a spinal disc bulges or ruptures directly into the neural foramen—the narrow passageway where a spinal nerve root exits the spinal column—causing compression that often leads to radiating pain, numbness, or weakness.
A foraminal disc herniation compresses the exiting nerve root. Therefore, an L4/L5 foraminal disc herniation affects the L4 nerve root, which may cause quadriceps weakness, sensory changes along the medial leg, and a decreased patellar tendon reflex.
Weak extension of the great toe indicates L5 nerve-root involvement and is more typical of a paracentral L4/L5 disc herniation, which compresses the traversing L5 nerve root. Clonus is an upper motor neuron finding that indicates cervical myelopathy, and a decreased ankle reflex usually indicates S1 involvement.

Where can I get more information about the top disc replacement surgeon Dr. Ritter-Lang?
Because a significant portion of Dr. Ritter-Lang’s patient base travels internationally for total disc replacement (TDR), his team maintains dedicated international educational and consultation portals:
Better Disc Replacement: betterdiscreplacement.com
Features: Detailed background on multi-level cervical and lumbar disc replacement techniques, patient case studies, and comprehensive guides comparing motion preservation against fusion.
Stenum Hospital Patient Portal: stenumhospital.com
Features: Information on international patient intake protocols, hospital amenities, surgical technology overviews, and access to a preliminary remote MRI review process.
Professional Background & Credentials
Clinical Focus: Over 30 years specializing in intervertebral disc prosthetics, complex multi-level reconstructions, and anterior/abdominal approaches to the spine.
Surgical Experience: Has completed thousands of motion-preserving spine procedures utilizing advanced implants such as M6-C, M6-L, ProDisc, and Mobi-C.
Early Foundations: Trained under Prof. Kurt Schellnack and Dr. Karin Büttner-Janz at Charité University Hospital in Berlin—the research team credited with developing the original Charité artificial disc.
People go to Germany for back surgery primarily to access advanced motion-preserving procedures, artificial disc replacements, and dynamic stabilization systems that may be newer, less restrictive, or harder to find in North America.
