According to Enard et al 2002, the fact that these two differences are fixed in the human genome, whereas no fixed substitutions occurred in the lineage of our closest relatives, the chimpanzees, suggests that those changes were strongly selected for in our lineage; Enard et al. put the date of fixation of these changes in the human population at around 200,000 years ago.
The age of the blocks/sections was determined by identifying the duration between the date of fixation (date of surgery) and the date of extraction (arrival date at the Peter MacCallum Cancer Centre).
Date of protocol fixation was 1st December, 2008 and Anticipated trial start date was 5th January , 2009
Label the container with the patient's full name, date of birth, date and time of fixation.
External fixation period was from the date of surgery to fixator removal.
Hospital of surgery, anonymized (encrypted) surgeon, type of surgery, date of surgery, surgical approach, fixation, and characteristics of the prosthesis (as specified below) are also registered.
This database contains the following data: country, age, sex, operated side, diagnosis, date of primary THA, hospital code, type of fixation of the prosthesis, type of bone cement, date of death (if applicable), and cause and date of eventual revision.
The data gathered include information on patient identity, date of operation, indication for surgery, type of implant, method of fixation, duration of surgery, type of operating room ventilation, and the type of antibiotic prophylaxis used.
This paper provides an up-to-date review of the relevant history of uncemented hip replacements, key design features, mechanisms of fixation, current status, guidance to use and long-term results of uncemented hips.
This is an art of fixation.
What matters is the new act of fixation.
