The objective of this study was to examine the prevalence, characteris
tics, and outcomes of spine surgery among a membership of American ort
hopaedic surgeons with a particular interest in spine care [North Amer
ican Spine Society (NASS)] and a general membership of Canadian orthop
aedic surgeons [Canadian Orthopaedic Association (COA)]. A 25-item mul
tiple choice questionnaire was developed and mailed to both membership
s. The COA response rate was 45.9%; the NASS response rate was 45.8%.
Of those who replied, 17.2% had undergone spinal surgery, and the resu
lts differed significantly between the COA at 12.9% and NASS at 21.9%.
As a percentage of the total mailing, 7.7% had undergone spinal surge
ry. These results differed significantly between the COA at 5.9% and N
ASS at 9.7%. Although the surgery rate for NASS respondents was more t
han 1.5 times that of COA respondents, they had strikingly similar out
comes. They are a highly motivated, self-employed group who missed lit
tle work before and after having surgery.
