Evolution of Fracture care
►Pre-surgical era: casts, slings, and traction
►Early surgical era: fixation of some
“problem fractures”
►1980’s: Fixation of fractures to save lives
and reduce morbidity
Early Total Care
►1990’s-2000’s: Damage control surgery
►Now: Early Appropriate Care

Therapy implications
►“Life is motion; motion is life”
►Articular cartilage nutrition
►Ligament and tendon healing
Orientation of collagen with controlled stress
►Muscle activity prevents contracture and
atrophy
►Bone healing responds to load

► Prospective observational study - 569 patients
2 and 7 year follow up
► Less complications in amputations
► Less hospitalizations in amputations
►Functional outcomes equal at two
years but early cost $ much more money and time with added loss of social, family and work life with salvage group
► Outcome dependent on self efficacy, education, race, insurance
