Background:
Lumbar disc herniation (LDH) is associated with great morbidity
and significant socioeconomics impact. Studies have shown that most LDH can
be treated effective conservatively. However for the group of patients where
pain and disability is unacceptable, surgical intervention provides effective clini-
cal relief in many cases. Several factors may influence the outcome of surgery
for LDH, including obesity and prolonged time of symptoms. Data from the
Danish National Healthprofile 2010 state that 47% of the danish population is
overweight (BMI ≥ 25) and about 13% is classified as obese (BMI ≥ 30).
Purpose / Aim of Study:
To investigate if obesity is correlated with surgical
outcome and whether overweight patients has a delayed time of surgery com-
pared with non-obese patients.
Materials and Methods:
832 patients with first-time LDH were included
in a Single-Center Study. Data were prospectively collected in DaneSpine,
the Danish National Spine Register. The patient reported outcome measures
(PROMs) EQ5D, SF36, ODI, VAS-leg and -back were correlated with duration
of symptoms. A comparison between subgroups of BMI and 1-year follow-up
PROMs were performed. Data was analysed with STATA.
Findings / Results:
Overweight and obese patients have symptoms-relieve
following LDH surgery, but the outcome is inferior to patients of normal weight.
Patients with BMI ≥ 35 are treated conservatively for a longer time and have
an inferior outcome.
Conclusions:
Severe obesity delays time of surgery and influences the surgical
outcome.
