Thoracic Outlet Syndromes in Sport
Thoracic Outlet Syndromes in Sport
The symptoms correlated with TOS. The nature of the pain pointed to the existence of a mechanical cause. The relief provided when pushing the clavicle forward is likely to be a result of the thoracic outlet being opened, relieving impingement on the brachial plexus. The exclusion of other potential differential diagnoses supported this conclusion.
A lack of ischaemia or vascular symptoms excluded the presence of ATOS or VTOS, although vascular symptoms can occur in NTOS as a consequence to overactive sympathetic nervous fibres in C8–T1 being affected in the thoracic outlet. The value of Adson's test in diagnosing TOS is also limited, as it has been found to have a false-positive rate of 42%, is higher in individuals with carpal tunnel syndrome, and has been found to be negative in most cases of NTOS.
Clinical appearances and provocation tests were suggestive of a dynamic transient and mechanical restriction of the nerves, which was supported by the presence of a flat clavicle, which is a risk factor for TOS. Neural tension testing suggested that the median nerve was the most affected.
