Sixty percent of workers were still work disabled 1 year after surgery. The strongest predictors of remaining disabled were the amount of work disability before surgery (OR = 1.85; 95% CI, 1.51 to 2.28), longer time between injury and TOS di agnosis (OR = 1.34; 95% CI, 1.09 to 1.64), and older age at injury (OR = 1.07; 95% CI, 1.00 to 1.13). There was no relationship between type of surgery, presence of any provocative tests, or experience of surgeon and work disability outcome. In follow-up surveys an average of 4.8 years after surgery, 72.5% of workers still reported they were "limited a lot" in vigorous activities. Compared with a nonsurgical sample of TOS patients, those receiving surgery had 50% greater medical costs and were three to fo ur times more likely to be work disabled. The outcome of TOS surgery among injured workers is worse than has generally been reported. The nonspecific neurogenic TOS diagnosis, the complexity of workers' compensation cases, and the adverse event profile ar e likely substantial contributors to the worse outcomes reported here. Well-designed prospective studies and randomized trials are required to elucidate any role of TOS surgery in nonspecific TOS. |
