Abstract

Background: Gender related differences in pain response and also in outcomes of spine surgery, possibly attributable to gender and genotype interaction, have been demonstrated previously. Our study explores gender related differences in patient-reported basic data before lumbar disc herniation (LDH) surgery within the framework of a national register.

Patients and Methods: Through a 11-year period, 15631 operations for LDH were prospectively registered. Among patient reported data collected were age, smoking, consumption of analgesics, walking distance, back and leg pain (VAS), SF-36, EQ-5D, EQVAS and ODI. 46% of the patients were females, mean age was 45. (range 12-92) years. Data were analyzed as comparison of means and 95% CI when normally distributed

Results: While consumption of analgesics and walking distance were similar for both genders, more females were smokers. SF-36 scores were inferior for females regarding especially BP, PF and SF but also VT and MH items. The table below displays means and 95% CI for scores recorded.

Discussion: Although some of the significant differences may not be clinically relevant on individual level, it is obvious that females scheduled for LDH surgery report higher levels of pain, inferior quality of life and higher disability than males. It would be of value to explore the causes for these differences.
