Patient demand, potential health-care savings, and the development of new
instrumentation and techniques have led to the rapid advancement of less
invasive surgical approaches. Minimally invasive surgery is an evolutionary
process that has transformed the surgical practices of surgeons not only in
the area of orthopaedics but also in other medical fields. Currently,
initiatives promoting minimally invasive surgery are under way for total hip
arthroplasty as well as spine surgery, in an attempt to avoid highly invasive
open procedures that result in slower rates of recovery for the patient.
