Summary
Split cord malformations (SCMs) are rare spinal anomalies. Two unusual cases with dorsal bony spurs challenge current classification, highlighting the need for further embryological research.
Area of Science:
- Neuroscience
- Developmental Biology
- Spinal Surgery
Background:
- Split cord malformations (SCMs) are rare congenital spinal anomalies.
- Current classification systems and embryological understanding remain debated.
- Pang's unified theory attempts to explain SCMs via neuroenteric canal closure errors.
Observation:
- Presents two unique cases of SCMs featuring a dorsally located bony spur.
- Radiological, clinical, and surgical data were analyzed for these cases.
- These specific SCM variants did not fit within the existing unified theory framework.
Findings:
- The reported cases of SCMs with dorsal bony spurs present a classification challenge.
- The unified theory may not encompass all SCM embryological mechanisms.
- A dorsal bony septum variant in SCMs requires consideration during surgical interventions.
Implications:
- Further embryological research is essential to fully understand SCM development.
- Surgical strategies for SCMs should account for the dorsal bony septum variant.
- This study contributes to refining the classification and understanding of rare spinal anomalies.
