The Ninth Thoracic Vertebra

The ninth dorsal segment is next on the list for my Marion Clark exploration. A lesion of the ninth dorsal is most often an anterior displacement or a torsion according to Clark. Considering the rotational and flexion bias of the dorsal vertebrae this should be fairly clear. From a pathology point of view the anterior displacement is more likely problematic due to the decrease of size in the intervertebral foramina. Continue reading

The Tenth Thoracic Vertebra

If you are reading Marion Clark’s book, this is one of the easier chapters to summarize…because he does it for you. I will provide that summary as well as some other thoughts (as I am prone to do). Continue reading

Still In The Junction: The Eleventh Thoracic Vertebra

I haven’t forgotten my Osteopathic terminology – the only time I will use the term thoracic in place of dorsal is in the title of my posts! It is now time to continue up the column to the eleventh dorsal segment. Continue reading

The Twelfth Thoracic Vertebra

To keep this next group of Marion Clark posts more in line with Osteopathic scholarship I will generally refer to thoracic vertebrae as dorsal vertebrae (we have to keep the language of Osteopathy alive!). That being said, it is now time to take a look at the twelfth dorsal segment. Continue reading

The First Lumbar Vertebra

It has been a while since I had the chance to delve in to Marion Clark so I have to get back to work and keep digging! Following my previous path I am now going to examine what Clark has to say about the first lumbar segment. As usual, I will start with some relevant anatomy. Continue reading

The Second Lumbar Vertebra

Now we head on up to the second lumbar segment. The second lumbar segment is very interesting as it is primarily in charge of the evacuation functions as well as some reproductive functions. I will explain those points soon. Continue reading

The Third Lumbar Vertebra

Continuing upwards it is now time for me to write about the third lumbar segment. I will continue to show that most lesions within the lumbar spine are group lesions and highlight that as the reason for the pelvis being the first adjustment. Continue reading
