WORKSHOP OBJECTIVES
Review the history of the AO Describe bone properties and fracture types Relate how bones heal Identify when fractures are treated surgically
(also called “indications”) Discuss specific fractures and the implants used Practice the techniques on artificial bones

WHY THE AO STARTED
High percentage of disabilities after motor vehicle and skiing accidents
Swiss dissatisfied with methods of fracture treatment in the 1940’s
![Page 10: WELCOME Introduction to an AO Workshop for Operating Room Personnel Indications for Internal Fixation.](https://reader036.fdocuments.us/reader036/viewer/2022062511/551b7a88550346d6338b5330/html5/thumbnails/10.jpg)
AO ASIF
Arbeitsgemeinschaft fur Osteosynthesfragen Association for the Study of Internal Fixation
Founded in 1958 by small group of Swiss surgeons
Dedicated to improving the care of patients with musculoskeletal injuries

INSTRUMENTATION
Instrumentation is one of the “pillars” & started in early 60’s to manufacture implants and instruments to achieve AO’s principles
SYNTHES is the commercial arm of AO
Instruments standardized worldwide

AO COURSES
Started in 1960 for surgeons & 1963 for O.R. personnel (ORP)
Early emphasis on teamwork 1963 - 2008
1,965 ORP courses 136,000 participants More than 70 countries

TYPES OF FRACTURES Amount of force, direction of force, and soft
tissue attachments determine fracture patterns: Transverse Oblique & Spiral Impacted Comminuted
Each pattern requires an implant with different biomechanical properties to resist body’s forces

BONE HEALING
How bone heals depends on the How bone heals depends on the stability of the fracture fixation and the stability of the fracture fixation and the motion between the fragmentsmotion between the fragments
Relative stability – some motionRelative stability – some motion Absolute stability – no motionAbsolute stability – no motion

Absolute stability Absolute stability comes from comes from compression of bone compression of bone fragmentsfragments
Achieved with lag Achieved with lag screws and screws and compression platescompression plates

Summary
Lag screws & compression plates provide absolute stability & direct bone healing
Casts, ex fix and IM nails provide relative stability & indirect bone healing
Both have their place in internal fixation

When Should You Consider Surgery?(Indications)
Internal fixation should be used only if the disadvantages of conservative treatment can be overcome by surgical treatment
Requires knowledge of the techniques &
adherence to the principles
