Discussion & Conclusion

Q: Is it related to the results presented before? Do you consider them as coherent?

A: Good


Comments: The Discussion establishes that whether thoracic disc herniation (TDH) will be symptomatic or asymptomatic depends on the individual and the different levels of the thoracic spine. It also illustrates that TDH initiates at the posterior central annulus and the posterior longitudinal ligament (PLL) acts as the first barrier to limit thoracic disc prolapse. The study concludes that, based on the observation of this study, the cadaveric case presented in the report was most likely asymptomatic.

Further comments on the paper

Comments: The case report presents the case of incidental discovery of thoracic disc herniation (TDH) or thoracic disc prolapse (TDP) in an 89-year-old female cadaver. TDP is a rare occurrence in vivo and is even more rarely observed in cadavers. Symptomatic or asymptomatic thoracic disc herniation may depend on whether the herniation ruptures the barrier of the posterior longitudinal ligament (PLL). Based on the dimensions of the herniation the study proposes that the lesion was asymptomatic in life. The results of this study indicate that TDH may initiate at the posterior central area of the annulus where the deep layer of the PLL is composed of decussating annulus fibers. The observations of the study provide insights into detailed pathological changes in the anatomy of surrounding structures following disc prolapse. Most available reports on TDP are from live case studies hence findings of this study add to the very little literature available on post-mortem thoracic disc herniation.
