Overuse Bone and Tendon Injuries - Science and Theories of TomorrowSteve Pribut
Lecture presented in the Sports Medicine presentations section of the Annual Scientific Conference of the American Podiatric Medical Association. 2012. Washington, DC.
A four year old Doberman police dog was submitted to the Department of Pathology, College of Veterinary & Animal Sciences, Parbhani, for conduct of Post mortem examination with the history of violent & consistent barking and sudden death.
A case of concomitant Lisfranc dislocation and metatarsophalangeal dislocation of the hallux is rare. This is usually associated with high velocity trauma. The compound metatarsophalangeal dislocation with fracture of proximal phalanx and closed dislocation of cuneometatarsal joint dislocation had not been reported in literature. This is the first case of floating metatarsal with fracture proximal phalanx described in the literature. We report an unusual case of concomitant tarsometatarsal (Lisfranc) and 1st metatarsophalangeal (MTP) joint dislocations and fracture of the base of proximal phalanx of the great toe.

The Roman Empire A Historical Colossus.pdfkaushalkr1407
The Roman Empire, a vast and enduring power, stands as one of history's most remarkable civilizations, leaving an indelible imprint on the world. It emerged from the Roman Republic, transitioning into an imperial powerhouse under the leadership of Augustus Caesar in 27 BCE. This transformation marked the beginning of an era defined by unprecedented territorial expansion, architectural marvels, and profound cultural influence.
The empire's roots lie in the city of Rome, founded, according to legend, by Romulus in 753 BCE. Over centuries, Rome evolved from a small settlement to a formidable republic, characterized by a complex political system with elected officials and checks on power. However, internal strife, class conflicts, and military ambitions paved the way for the end of the Republic. Julius Caesar’s dictatorship and subsequent assassination in 44 BCE created a power vacuum, leading to a civil war. Octavian, later Augustus, emerged victorious, heralding the Roman Empire’s birth.
Under Augustus, the empire experienced the Pax Romana, a 200-year period of relative peace and stability. Augustus reformed the military, established efficient administrative systems, and initiated grand construction projects. The empire's borders expanded, encompassing territories from Britain to Egypt and from Spain to the Euphrates. Roman legions, renowned for their discipline and engineering prowess, secured and maintained these vast territories, building roads, fortifications, and cities that facilitated control and integration.
The Roman Empire’s society was hierarchical, with a rigid class system. At the top were the patricians, wealthy elites who held significant political power. Below them were the plebeians, free citizens with limited political influence, and the vast numbers of slaves who formed the backbone of the economy. The family unit was central, governed by the paterfamilias, the male head who held absolute authority.
Culturally, the Romans were eclectic, absorbing and adapting elements from the civilizations they encountered, particularly the Greeks. Roman art, literature, and philosophy reflected this synthesis, creating a rich cultural tapestry. Latin, the Roman language, became the lingua franca of the Western world, influencing numerous modern languages.
Roman architecture and engineering achievements were monumental. They perfected the arch, vault, and dome, constructing enduring structures like the Colosseum, Pantheon, and aqueducts. These engineering marvels not only showcased Roman ingenuity but also served practical purposes, from public entertainment to water supply.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
The French Revolution, which began in 1789, was a period of radical social and political upheaval in France. It marked the decline of absolute monarchies, the rise of secular and democratic republics, and the eventual rise of Napoleon Bonaparte. This revolutionary period is crucial in understanding the transition from feudalism to modernity in Europe.

CASE
• 24 yo M football player
• Another player rolled over his ankle from behind
• ANKLE DISLOCATION:
• • Usually posterior
• • Often associated with fracture and ligamentous injury
• Reduction:
• • Place one hand behind heel, with other over dorsum of foot.
• • Downward and anterior traction, with foot plantar-flexed initially.
• • Finally bring ankle back to 90 degrees flexion.
• Clinical Pearl:
• Put the knee in a slightly flexed position (20-30 degrees) during
the
reduction to reduce tension at the ankle.
• Post-reduction:
• • Immobilize in short leg, 3-sided splint, ankle at 90 degrees
• • Follow up with Orthopedic surgeon
32
33. 2/3/2010
case
• 20 year old male twisted his ankle while ―snowboarding‖
• Exam: Ankle is swollen, diffusely tender, and plain films are
negative.
• Ankle Sprain:
• • R.I.C.E. (rest, ice, compression, elevation)
• • Functional immobilization
• o ACE, AirCast, taping, etc
• • Crutches
• o Weight-bearing as tolerated
• • Follow up exam
• o Approximately two weeks after injury
• o Repeat physical exam for ligamentous damage
• o Most patients will be much improved
• o A few may have persistent pain, swelling, and joint effusion,
• suggesting the possibility of occult fracture.
• When should I consider CT or MRI for
occult ankle fracture?
• Consider CT or MRI in the setting of negative
plain films, and:
• o High clinical suspicion
• o Persistent pain, swelling, effusion at follow-
up
• Important occult fractures of the ankle/foot:
• o Talar dome
• o Tillaux (lateral tibia)
• o Calcaneus, Navicular
• o Lateral process of the talus
33
34. 2/3/2010
• Haapamaki, American Journal of
Roentgenology, 2004
• Retrospective study, over 3 years
• 344 patients with a fracture on ankle / foot CT
• CT’s ordered to delineate fracture, or to r/o
occult fracture
• Most common occult fx in ankle (not
visualized on plain films):
• Calcaneus (20)
• Talus (15)
• Tillaux (7)
• Pearls:
• 1) CT helpful for:
• a. High suspicion (mechanism, exam)
• b. Poor recovery
• 2) High risk situations:
• a. Fall from height—Calcaneus
• b. Adolescent—Tillaux
• c. Snowboarding—Lat. process of
Talus
