Summary
Intradural disc herniation in the cervical spine is rare. Surgical technique modification is key to avoiding complications in these cases.
Area of Science:
- Neurosurgery
- Spinal Surgery
- Radiology
Background:
- Intradural disc herniation (IDH) in the cervical spine is an uncommon condition.
- Surgical management of IDH requires careful technique to prevent complications.
Observation:
- A 55-year-old male presented with radicular symptoms due to a C4-5 intradural disc herniation.
- The patient underwent anterior cervical discectomy and fusion.
- A dural defect was identified during the surgical procedure.
Findings:
- Retrospective MRI review revealed subtle signs of the intradural disc.
- These included a T2 hyperintense ring surrounding the herniation.
- Spinal cord deformation was less than anticipated for the herniation's size.
Implications:
- Early identification of subtle MRI findings can aid in diagnosing cervical intradural disc herniation.
- Awareness of these findings can guide surgical planning and technique modification.
- This case highlights the importance of meticulous surgical technique for intradural pathologies.

01:07Reflection of Waves
4.5K
When a wave travels from one medium to another, it gets reflected at the boundary of the second medium. A common example of this is when a person yells at a distance from a cliff and hears the echo of their voice. The sound waves (longitudinal waves) traveling in the air are reflected from the bounding cliff. Similarly, flipping one end of a string whose other end is tied to a wall causes a pulse (transverse wave) to travel through the string, which gets reflected upon reaching the wall. In...

02:57The Sense of Self: Reflected Self-Appraisal and Social Comparison
55.5K
According to Charles Cooley, we base our image on what we think other people see (Cooley 1902). We imagine how we must appear to others, then react to this speculation. We don certain clothes, prepare our hair in a particular manner, wear makeup, use cologne, and the like—all with the notion that our presentation of ourselves is going to affect how others perceive us. We expect a certain reaction, and, if lucky, we get the one we desire and feel good about it. But more than that, Cooley...

Reporting and recording are crucial in data documentation. The timely, thorough, and accurate documentation of facts is essential when recording patient data. Failure to record findings during an assessment or interpretation of a problem will result in loss of information and make the patient document unreliable. The reader is left with general impressions if the information is not specific. A recording is documenting data of the individual's health information in a traceable, secure, and...
