METHODS: The length of time off work before surgery was recorded in weeks. The mean percentage improvement between preoperative and 24-month follow-up scores were analyzed.RESULTS: There was a significant relationship between duration off work preoperatively andclinical outcome (p!.05). The length of time off work preoperatively was more strongly relatedto outcome than was surgery type, insurance type, job demand, or preoperative VAS and Oswestryscores. Further analysis of the data identified a window of approximately 0 to 13 weeks off workpreoperatively that was related to significantly greater improvements on visual analog scales (VAS)and Oswestry scores after surgery compared with patients who were off work for more than 13weeks preoperatively. Although the subgroup off work for more than 13 weeks improvedsignificantly from their preoperative status, the improvement was not as great as in the subgroup of fwork for a shorter duration.CONCLUSIONS: The results of this study found that patients off work for a longer duration before surgery improved significantly postoperatively, but had less favorable clinical outcomes thanpatients off work for a lesser duration. This study suggests a window of approximately 13 weeksoff work before surgery after which clinical improvement is reduced. Implications of this findingmay be that once a patient becomes unable to work for an extended period, more rigorous psycho
