Osgood-Schlatter Disease

Other Known Aliases – tibial tubercle apophysitis

Definitiontraction apophysitis of the proximal tibial tubercle at the insertion of the patellar tendon.

Clinical SignificanceMost commonly occurs in adolescents as a result of overuse stress in athletics requiring explosive running, jumping, or cutting. This places an extreme amount of stress on the tibial tubercle and may lead to a chronic avulsion. As the new healing callous is laid down, a pronounced deformity may develop.

HistoryNamed after two physician who contemporaneously published on this condition in the same year. Robert Bayley Osgood (1873-1956), was an American orthopaedic surgeon, and received his medical doctorate from Harvard University in 1899. Dr. Osgood spent his entire career practicing in Boston at Massachusetts General Hospital and teaching at the Harvard Medical School. Carl Schlatter (1863-1934), was a Swiss physician and surgeon, and received his medical doctorate from the University of Zurich in 1889. Dr. Schlatter was a skilled surgeon and had a primary interest in trauma and causality medicine during World War I. Both physicians were well respected educators and professors of their time and both published their findings of this condition in 1903.

Maisonneuve Fracture

 

Other Known Aliasesnone

 

Definitionspiral fracture of the proximal third of the fibula caused by pronation with external rotation

 

Image result for maisonneuve

Clinical SignificanceThis injury is a sequelae of significant ankle trauma with disruption of the distal tibiofibular syndesmosis and can be unstable.  It is also one of the criteria of the Ottawa Rules of the Ankle so you don’t miss these

 

History – Named after Jules Germain François Maisonneuve (1809-1897), a French surgeon who studied under Guillaume Dupuytren in the mid-1800s.  He first reported this injury pattern in 1840 in the article entitled Recherches sur la fracture du Péroné.  He was also the first surgeon to advocate the use of external fixation in the management of ankle fractures

Question

 

What rheumatologic disease can be summed up the phrase “can’t see, can’t pee, can’t climb a tree”?

 



Answer

 

The triad of ocular symptoms (conjunctivitis, uveitis, episcleritis, keratitis), genitourinary symptoms (dysuria, urethritis, cervicitis) and musculoskeletal symptoms (arthritis, enthesitis, dactylitis) are diagnostic of reactive arthritis.

Hutchinson Fracture

 

Other Known AliasesChauffeur fracture, backfire fracture

 

Definition – intra-articular fracture of the radial styloid

 

Chauffeur fracture

 

Clinical SignificanceThis 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.

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

Bouchard’s Nodes

 

Other Known Aliasesnone

 

Definitionnodular growths on the proximal interphalangeal joints of the fingers and toes

 

 

Clinical SignificanceMost 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.
