Dynamic Motion X-ray

Dynamic Motion X-Ray (DMX) Imaging Visualises Spinal Movement


“The Digital Motion X-Ray (DMX) imaging at the American private spinal surgery company ‘NeuroSpine Institute‘ is being used to identify injuries from a car accident or disc injury often missed by traditional X-rays and MRIs. The doctor can access diagnostic information in minutes instead of hours or days.”

N.B. C2/3 and L sidebending /rotation restriction? Also, interesting to see the stability of the C1/2 segment during movement in the intra-oral section, and how the upper cervical segments do most of the work of rotation, as expected.

….I bet they don’t have one at the local hospital though 🙁

‘Poetry in Water’ – ‘Hybrid’ CST Video

Although we don’t talk about CST very often, this film is well worth watching.

The practitioner in this short film, Steve Karle, says he is synthesising Biodynamic Craniosacral Therapy with a number of other approaches, including Alexander Technique and elements of dance ‘based on on alignment, precision and neutrality’.

Watching the film, I found myself fascinated with the therapeutic relationship encapsulated in the moment, and the obvious journey and quietness that the woman experienced.

However, from an osteopathic point of view, I was also wondering about how to create a fulcrum and maintain boundaries in such a weightless, dynamic environment: it would be a whole new skill.

The TMJ

TMJ Anatomy And Function

I see a lot of patients with varying grades of TMJ dysfunction – from vague aching following dental intervention or bite change, to disc disorders in the joint and associated complexes of muscle tightness and pain with wider musculoskeletal consequences.

The TMJ joint demonstrates a two-phase mechanical movement during opening, mainly consisting of hinging then sliding/hinging movements of the mandibular condyle in the glenoid fossa of the temporal bone. In cases of dysfunction, the articular disc often becomes displaced and degenerated, so that a common presentation is TMJ clicking and even locking.

This video presents moving dissections of the joint, demonstrating normal function, opening and closing, medial and lateral disc displacements and posterior disc ligament ruptures. If you excuse the *slightly* dated music at the beginning and end of the film, it is a very clear demonstration of the anatomy of TMJ disorder.

0:38 – The Anatomy of the Joint

2:46 – The Normal TMJ Joint

3:30 – The Biconcave Disc – showing small central perforation

5:08 – Anterior Disc Displacement – clicking on closing AND opening

6:15 – Anteromedial Disc Displacement – showing biplanar disc and medial/lateral movement of the disc

7:30 – Medial Disc Displacement

8:25 – Anterior Disc displacement – disc consistently anterior to the condyle

9:25 – Degenerative Joint – large perforation

The Rhoton Collection - The Anterior Skull Base

The Rhoton Collection – State-Of-The-Art Dissection

The renowned neurosurgeon, Albert J. Rhoton Jnr M.D. presents this incredible series of dissections of the anterior skull base. Intended for use as revision for neurosurgeons involved with learning an endoscopic approach, the anatomy presented here helps to illustrate the relationship between these structures and shows just how closely-packed the cranial contents are.

Anatomy As You’ve Never Seen It Before…

For those who have an interest in being able to visualise the anatomy they are working on, these slides are invaluable. As Dr. Rhoton says, we need to develop “see through x-ray vision”.

Of particular interest to osteopaths in this video, at 16mins 25 secs there begins a detailed run-through of the osteology of the anterior neurocranium, including the bony sinuses.

This video – The Anterior Skull Base – is part of a playlist of 14 comprehensive presentations covering all parts of the skull and brain – check the ‘Playlist’ on the top left of this video window or click here for the full collection on YouTube. Again, the quality can be switched up to 720p for high quality viewing by clicking the ‘cog’ icon at the bottom-right of the player window.

Cranial Foramen

Cranial Foraminae And Their Contents – HD Anatomy

An understanding of the anatomy of the skull is essential when working with the cranial mechanism. Learning the skull foraminae and their contents provides a particular challenge, but is also absolutely fundamental in this approach.

It has been said that the most effective way to learn this is to sit down in front of a skull specimen with a copy of Gray’s in one hand, and a glass of wine in the other (!)

However, the video above, clearly demonstrates the various foramen of the skull, and playback can be viewed in high resolution, (after pressing play click on the cog icon on the bar at the bottom and choose the quality from the list).

Once again, this is only an introduction to cranial anatomy relevant to osteopathic practice, and much more detail is available on our upcoming (July) 5-day course:

Autism – What We Know And What We Don’t Know (Yet)

This factual TED talk about autism is a concise and enlightening lecture that reviews our current state of understanding, particularly from a genetic perspective, of this challenging condition.

Wendy Chung, director of clinical research at the Simons Foundation Autism Research Initiative, begins by looking at the epidemiology of autism as a diagnosis, and proposes some possible causes for the marked increase in presentation in recent years. She also discusses the previous worry about vaccines as aetiology, and then provides insight into causes and correlations that are supported by real evidence.

After a very clear and interesting section on the genetics of autism, Ms Chung also presents her recent research on identifying gene mutations that lead to ASD development, and shows some of the new ways that early diagnosis in infants is being achieved.

As an alternative viewpoint – Temple Grandin, diagnosed with autism herself, provides wonderful insight into the autistic mind:

Fascia Collagen Tendrils

The Fascia – Strolling Under The Skin

Three clips from the amazing images of living fascia made by Dr. Claude Guimberteau, including views of sliding collagen fibres capable of instant morphological change, and also illustration of tensegrity phenomena. (warning – some images of dissection)

I write at length of the universality of the fascia to impress the reader with the idea that this connecting substance must be free at all parts to receive and discharge all fluids, and to appropriate and use them in sustaining animal life, and eject all impurities, that health may not be impaired by dead and poisonous fluids.

A knowledge of the universal extent of the fascia is imperative, and is one of the greatest aids to the person who seeks the cause of disease.
—A. T. Still Philosophy and Mechanical Principles of Osteopathy

The narrator often uses poor pronunciation (see ‘stab-ilise’, and ‘colla-gene’) but these endoscopic films of the fascia otherwise give a fascinating insight into the hidden world of our collagen framework.

Abraham Verghese - A Doctor's Touch

The Importance Of Touch


Filmed July 2011 at TEDGlobal 2011

Physician and writer Abraham Verghese speaks earnestly and with great humanity about the powerful role that touch plays when helping our patients in a therapeutic setting.

Transcending the clinical routine, Verghese portrays, sometimes with poetic intensity, the fundamental human need to connect – without which we might risk losing sight of the patient as a person.

“…the power of the human hand – to touch, to comfort, to diagnose and to bring about treatment”

Obviously, as osteopaths we work with touch in a way that is central to our interaction – in examination and treatment – powerful allies when helping a person to recover. Nonetheless, this talk entreats us to reaffirm the responsibility this interaction brings, and to best use the opportunity we have to help.

X-ray Body In Motion

Just a great video 🙂

From the web-page:

“A visual study/exploration of the body in motion with a focus on yoga poses. Our goal for this piece was to create a realistic representation of radiological (x-ray) imaging.

Instead of just creating a still image, however, we wanted to combine the beautiful moves of yoga with this new visual approach to bring the full human skeleton to life.

Technical challenges included aspects such as achieving proper bone densities and representing actual bone marrow inside each individual bone.

The Power Of Neuroplasticity

This film is an amazing and moving example of paediatric neuroplasticity. The autoimmune syndrome Rasmussen’s Syndrome was causing this girl multiple daily seizures, and cognitive impairment, so to halt the progress of the neural destruction neurosurgeons performed a hemispherectomy.

The outcome was a total cessation of seizure activity, and after much rehabilitation, a greatly improved quality of life.
(caution – some possibly disturbing scenes)
