Dr. Rhoton's Anatomy 2D and 3D

Medtronic and Dr. Rhoton put together an amazing YouTube series on "Rhoton Anatomy" in both 2D and 3D versions. I highly recommend checking them out. An incredible amount of effort and detail went into these!
Dr. Rhoton Biography
Dr. Rhoton
Dr. Albert L. Rhoton, Jr. attended Washington University School of Medicine, graduating with the highest academic standing in the class of 1959. He completed his neurosurgical training at Washington University and joined the staff of the Mayo Clinic in Rochester, Minnesota in 1965. He became Professor and Chairman of the Department of Neurological Surgery at the University of Florida in 1972.
Dr. Rhoton has served as President of the American Association of Neurological Surgeons, the Congress of Neurological Surgeons, the Society of Neurological Surgeons, the North American Skull Base Society, the International Interdisciplinary Congress on Craniofacial and Skull Base Surgery, the Florida Neurosurgical Society, and the International Society for Neurosurgical Technology and Instrument Invention. He served as the Honored Guest of the Congress of Neurological Surgeons and was awarded the Cushing Medal of the American Association of Neurological Surgeons in 1998, the highest honor given by the two largest neurosurgical societies in the United States. He has been awarded the Medal of Honor of the World Federation of Neurosurgical Societies, and has served as the Honored Guest or been elected to Honorary Membership in neurosurgical societies in Africa, Asia, Australia, Europe, and North and South America.
He has published over 400 scientific papers. He has received the Golden Neuron Award of the World Academy of Neurological Surgeons and was selected as the 2011 “Neurosurgeon of the Year” by the journal World Neurosurgery. He completed the Millennium and Anniversary Issues of Neurosurgery and a book entitled “Cranial Anatomy and Surgical Approaches,” which has been translated into several languages. He has received an Alumni Achievement Award from Washington University School of Medicine and both a Distinguished Faculty Award and a Lifetime Achievement Award from the University of Florida.
Friends, colleagues, and former residents contributed nearly $2 million to the University of Florida Foundation to create the Rhoton Chairman’s Endowed Professorship at the University of Florida, a gift that has grown to more than $6 million. This is in addition to 11 endowed chairs that Dr. Rhoton has raised for neurosurgery over the years. He and his wife, Joyce, have four children, all pursuing medical careers.

Aphasia

I have always found aphasia incredibly interesting and terrifying all at the same time. Imagine not being able to communicate with language as smoothly as you do everyday. It is something that many of us take for granted.

Definition:
the loss or defect of language (speaking fluency, reading, writing, understanding of written or spoke words)

What are the 4 types of aphasia?
1. Wernicke's 
2. Broca's
3. conduction
4. global

Potential causes:

  • stroke
  • brain trauma
  • brain tumor
  • alzheimer's disease
Wernicke's
-receptive, fluent aphasia
-pt has hard time comprehending written or spoken language
-fluid speech, but difficult to understand

Broca's
-expressive, nonfluent aphasia
-speech is slow and requires effort
-few words used
-good comprehension of language

Conduction
-disturbance in repetition
-pathology involves the connections between Wernicke's and Broca's

Global
-often associated with RIGHT hemiparesis
-defect in all areas of language


How to treat
-many recover spontaneously in 4-6 weeks
-speech therapy

Managing Shoulder Injuries

The American Family Physician is the peer-reviewed journal put out by the AAFP and they often have great stuff. This is an older article, but still incredibly relevant.

A shout out to my ortho roots...

Gross Anatomy Videos

University of Michigan Medical School has a wealth of medical resources online. One of the ones that I used most throughout school was the dissection videos.
