Hutchinson Fracture

 

Other Known Aliases – Chauffeur fracture, backfire fracture

 

Definition – intra-articular fracture of the radial styloid

 

Chauffeur fracture

 

Clinical Significance – This injury most commonly occurs from either direct trauma to the dorsum of the hand or from FOOSH with forced dorsiflexion and abduction

 

History – Named after Jonathan Hutchinson (1828-1913), who was an English physician and surgeon and received his medical doctorate from St. Bartholomew’s Hospital in London in 1850.  He enjoyed a prolific career practicing in ophthalmology and pathology, while also serving as president for numerous medical societies.  Dr. Hutchinson also produced more than 1200 medical articles and study extensively on infectious diseases.  In 1908, he was knighted by Edward VII for his contributions to medicine.  The colloquial term of chauffeur fracture comes from the fact that when the chauffeur would hand crank the car and the car backfired, the handle would shoot back and impact the palm of the hand.

Heberden’s Nodes

 

Other Known Aliases – none

 

Definition – osteophytic growths on the distal interphalangeal joints of the fingers and toes

 

Heberden-Arthrose.JPG

 

Clinical Significance – Most commonly seen in osteoarthritis and similar to, but much more common than, Bouchard’s nodes of the proximal interphalangeal joints.  They are much more common in women and seem to have a genetic predisposition.

 

History – Named after William Heberden (1710-1801), who was an English physician and received his medical doctorate from St. Johns College in Cambridge in 1739, where he made his name a distinguished medical lecturer at the university.  He received fellowship in the Royal College of Physicians in 1746 and then the Royal Society in 1749.  He njoyed a prolific medical practice in London and Paris for over 30 years.  While semi-retired, he worked on a collection of papers for the Royal College of Physicians to be transcribed into a three volume textbook entitled Medical Transactions.  These were eventually revised and transcribed in English, by his son William Heberden the younger, which included a chapter on arthritis by Heberden the elder describing these findings.

Question

 

Thoracic outlet syndrome is constellation of signs and symptoms due to compression of the neurovascular bundle in the upper thorax.

  1. What are the three main classifications?
  2. What structures can compression the bundle?
  3. What are the three physical examination maneuvers you can do at the bedside to help diagnoses?

Answer

 

  • The main classifications of thoracic outlet syndrome are:
    • Neurogenic
      1. Most common
      2. Signs and symptoms include pain, paresthesias, numbness, and weakness
    • Venous
      1. 2nd most common
      2. Signs and symptoms include hand swelling, pain, cyanosis with repetitive activity
    • Arterial
      1. Least common
      2. Signs and symptoms include pain, pallor, paresthesias, and poikilothermia not related to activity
  • There are three anatomic areas that thoracic outlet obstruction can occur in:
    • Scalene Triangle
      1. Most common site of neurogenic
    • Costoclavicular space
      1. Most common site of venous
    • Pectoralis minor space
      1. Most common site for arterial

  • There are several bedside maneuvers you can perform to help distinguish between these types

Bouchard’s Nodes

 

Other Known Aliases – none

 

Definition – nodular growths on the proximal interphalangeal joints of the fingers and toes

 

 

Clinical Significance – Most commonly seen in osteoarthritis and similar to Heberden’s nodes of the distal interphalangeal joints, though they are less common.

 

History – Named after Charles Jacques Bouchard (1837-1915), a French pathologist who received his medical doctorate in 1866 while studying under the famous Dr. Jean Martin Charcot. He practiced at the Bicêtre Hospital where he was appointed chair of general pathology in 1879.  His seminal work was the Traité de Pathologie Générale, which was a compendium of medical pathology and where the description of his eponymous findings were first recorded.

Jones Fracture

 

Other Known Aliases – none

 

Definition – fracture of the base of the 5th metatarsal at the metaphyseal-diaphyseal junction

Image result for jones fracture

Clinical Significance – Fairly easy radiographical diagnosis to make, but careful examination must distinguish between acute injuries in Zone 1 and 2 and chronic injuries in Zone 3.

Image result for jones fractureImage result for jones fracture zones

History – Named after Sir Robert Jones (1857-1933), a Welsh orthopaedic surgeon and received his medical doctorate from the Liverpool School of Medicine in 1887 and achieved fellowship in 1889.  Along with his uncle, he was a pioneer in the diagnosis and management of fractures.  He first described the injury that bears his name in 1902 in the Annals of Surgery entitled “Fracture of the Base of the Fifth Metatarsal by Indirect Violence”.  This paper was a six patient case report on the injury pattern and Dr. Jones was patient number one having injured his foot several months prior dancing.  After Wilhem Rontgen published his discovery of x-rays in 1895, Dr. Jones adopted this new modality fully in the practice of orthopaedics and published the first clinical radiograph in 1896 about a 12yo with a bullet lodged in his wrist that could not be found clinically and required a 2hr long exposure.
