Comparison of Athletes and Nonathletes Undergoing Thoracic Outlet Decompression for Neurogenic Thoracic Outlet Syndrome

Abstract

Background: Neurogenic thoracic outlet syndrome (NTOS) is the most common form of thoracic outlet syndrome (TOS) and may occur from injury, occupational stress, or athletic endeavors. Although most patients with NTOS will improve after first-rib resection and scalenectomy (FRRS), the prognostic risk factors for success remain unclear. Athletes are a very motivated and disciplined demographic and therefore should be a group more likely to respond to FRRS for NTOS than nonathletes. We hypothesized that athletes would do better after FRRS than nonathletes despite the added physical stress that sporting activity imposes.

Methods: We reviewed our office records for all patients treated for TOS from July 2009 to May 2014 and extracted demographic, historical, procedural, and follow-up data. We contacted these patients to complete a survey to assess patient-centered outcomes of FRRS and compared athlete versus nonathlete survey responses.

Results: Five hundred sixty-four patients had FRRS for NTOS, and 184 (33%) responded to the survey. Of the 184 who responded, 97 were athletes (53%) and 87 were nonathletes (47%). Survey results suggested that 87% were improved in pain medication use (athletes 93% vs. nonathletes 80%, P = 0.013), 77% would undergo FRRS on the contralateral side if needed (athletes 75% vs. nonathletes 79%, P = 0.49), 73% had resolution of TOS symptoms (athletes 80% vs. nonathletes 65%, P = 0.02), and 86% could perform activities of daily living without limitation (athletes 95% vs. nonathletes 77%, P = 0.0004). Although 24% of respondents required another non-TOS procedure (athletes 27% vs. nonathletes 22%, P = 0.6), 89% felt that they had made the right decision (athletes 93% vs. nonathletes 80%, P = 0.09). Multivariable analysis of age, race, gender, previous surgery, preoperative physical therapy, preoperative narcotic use, and athletic status confirmed that athletic status was a significant predictor for improvement in pain medication use, complete TOS resolution, and the ability to perform activities of daily living.

Conclusions: Most patients undergoing FRRS for NTOS are improved and satisfied with the result and indicate they made the correct choice to have FRRS. Although being an athlete was an independent variable for better outcomes in activity and pain medication use, their satisfaction after FRRS was similar to that in nonathletes. Further investigation is needed to determine if these findings are due to physical and/or psychosocial factors.
