Neurogenic thoracic outlet syndrome (TOS) is one of the most controversial pain syndromes of the upper limbs. The controversies revolve around both the diagnosis and treatment of the non-specific or subjective subtypes. Their diagnosis rests on a combination of history, suggestive symptoms and clinical examination. Proximal pain is primarily muscular in origin, while distal symptoms may be the result of intermittent nerve compression and/or myofascial pain syndrome. Stringent clinical criteria are required to confirm the diagnosis of subjective TOS...

Thoracic outlet syndrome, a condition due to neurovascular compression in the upper shoulder region, can be caused by chronic repetitive activity of the upper extremities. Studies have linked upper extremity musculoskeletal disorders to high-performance musicians who play bowed string instruments such as the violin or viola. We report herein a case series of five elite musicians, including three violinists and two violaists, who developed neurogenic thoracic outlet syndrome following years of intense practice...

BACKGROUND: Many publications report outcomes of surgical treatment for thoracic outlet syndrome (TOS); however, high-quality reviews and meta-analyses are lacking. This systematic review and meta-analysis summarizes and compares the outcomes and major complications of the surgical procedures for the 3 types of TOS: arterial, venous, and neurogenic. METHODS: MEDLINE, EMBASE, and CINAHL databases, and the Cochrane Database of Systematic Reviews were searched for papers published between January 1980 and February 2015, using the keywords thoracic outlet syndrome, and treatment and surgical...

BACKGROUND: Thoracic outlet syndrome (TOS) causes neurologic symptoms in 95% of cases and vascular symptoms in 5% of cases. Surgical resection is curative. Endoscopic-assisted transaxillary first rib resection has been previously reported. In this study we report a totally endoscopic video-assisted thoracoscopic surgery (VATS) approach using tailored endoscopic instruments. METHODS: Ten patients (8 women; average age, 32.3 ± 5.6 years) with TOS underwent VATS first rib resection following failure of symptom improvement with physiotherapy...

Thoracic outlet syndrome (TOS) is a group of disorders all having in common compression at the thoracic outlet. Three structures are at risk: the brachial plexus, the subclavian vein, and the subclavian artery, producing neurogenic (NTOS), venous (VTOS), and arterial (ATOS) thoracic outlet syndromes, respectively. Each of these three are separate entities, though they can coexist and possibly overlap. The treatment of NTOS, in particular, has been hampered by lack of data, which in turn is the result of inconsistent definitions and diagnosis, uncertainty with regard to treatment options, and lack of consistent outcome measures...

Thoracic outlet syndrome (TOS) refers to the compression of the neurovascular bundle within the thoracic outlet. Cases are classified by primary etiology-arterial, neurogenic, or venous. In addition to the typical symptoms of arm swelling and paresthesias, headaches have been reported as a potential symptom of TOS. In this report, we describe a patient with debilitating migraines, which were consistently preceded by unilateral arm swelling. Resolution of symptoms occurred only after thoracic outlet decompression...

BACKGROUND: High-performance throwing athletes may be susceptible to the development of neurogenic thoracic outlet syndrome (NTOS). This condition can be career-threatening but the outcomes of treatment for NTOS in elite athletes have not been well characterized. The purpose of this study was to utilize objective performance metrics to evaluate the impact of surgical treatment for NTOS in Major League Baseball (MLB) pitchers. METHODS: Thirteen established MLB pitchers underwent operations for NTOS between July 2001 and July 2014...

BACKGROUND: The concept of neurogenic thoracic outlet syndrome (N-TOS) including upper and lower plexus syndromes secondary to soft tissue neck injury after motor vehicle collisions (MVCs) has been contentious. We considered that analysis of objective data from this group of patients could provide insight into this controversial type of N-TOS. METHODS: During the 10-year period January 2001 through December 2010 we examined patients who had received a diagnosis of N-TOS following an MVC...

Thoracic outlet syndrome (TOS) is a disorder characterized by compression of the lower trunk of the brachial plexus, most often in association with anomalous congenital fibromuscular bands in the scalenic region. Early diagnosis is important, because the neurologic deficit associated with TOS may be irreversible. Using high-resolution ultrasound, we investigated 20 consecutive patients with clinical signs suggestive of TOS (all females, average age: 40.4 ± 14.9 y) and 25 control patients. In 19 patients, we identified a hyper-echoic fibromuscular structure at the medial edge of the middle scalene muscle, which indented the lower trunk of the brachial plexus ("wedge-sickle sign")...

Thoracic outlet syndrome (TOS) is a well-known disorder, but many aspects of its pathology, including its definition, has been disputed. True neurogenic TOS (TN-TOS) is a rare but well-defined clinical condition. TN-TOS results from the compression of the C8/T1 roots (dominant for the T1 root) or the proximal lower trunk of the brachial plexus by a fibrous band. The band extends from the first rib to either the tip of an elongated C7 transverse process or a rudimentary cervical rib. The most common presenting symptoms of TN-TOS are insidious-onset atrophy and weakness of the intrinsic hand muscles, predominantly in the thenar eminence and radial digit flexors...

Thoracic outlet syndrome is comprised of symptoms resulting from a compression of the neurovascular structures that pass through the intra-scalene triangle. This condition poses challenges in diagnosis due to the syndrome's vague definition, which only identifies the location of pathology without identifying which structures are specifically compromised. Thoracic outlet syndrome is categorized into vascular or neurogenic types with vascular cases subcategorized as arterial or venous and neurogenic cases subcategorized as true or disputed...

Neurogenic thoracic outlet syndrome (NTOS) is the most common type of TOS. Typically it results from impingement of the neurovasculature as it passes between the anterior and middle scalene muscles; this classic anatomical relationship being the foundation of clinical diagnosis. Positional testing relies on vascular compromise occurring when the subclavian artery is compressed in this space. This study describes several anatomical variations observed in this relationship. Sixty-five cadavers (35m/30f) were assessed to determine the frequency and extent of brachial plexus branching variants...

OBJECTIVE: To evaluate the diagnostic role of venous and arterial duplex scanning in neurogenic thoracic outlet syndrome (NTOS). METHODS: Retrospective review of patients who underwent duplex ultrasonography prior to first rib resection and scalenectomy (FRRS) for NTOS from 2005 to 2013. Abnormal scans included ipsilateral compression (IC) with abduction of the symptomatic extremity (>50% change in subclavian vessel flow), contralateral (asymptomatic side) compression (CC) or bilateral compression (BC)...

BACKGROUND: Thoracic outlet syndrome (TOS) is one of the most poorly understood syndromes. Neurogenic TOS is found in 95% of cases. The described anatomical spaces transform and evolve into 'entrapment spaces'. The aetiology is unclear. This study was based on the observation by a single surgeon that there appeared to be a high incidence of anatomical abnormalities in patients with neurogenic TOS. OBJECTIVE: To attempt to clearly define anatomical anomalies causing TOS...

Neurogenic thoracic outlet syndrome (nTOS) is caused by compression of the brachial plexus as it traverses from the thoracic outlet to the axilla. Diagnosing nTOS can be difficult because of overlap with other complex pain and entrapment syndromes. An nTOS diagnosis is made based on patient history, physical exam, electrodiagnostic studies, and, more recently, interpretation of MR neurograms with tractography. Advances in high-resolution MRI and tractography can confirm an nTOS diagnosis and identify the location of nerve compression, allowing tailored surgical decompression...

BACKGROUND: Neurogenic thoracic outlet syndrome is an underestimated cause of brachial weakness and pain. The subclavius posticus muscle (SPM) is an aberrant muscle originating from the medial aspect of the first rib reaching to superior border of the scapula, which may cause, depending on its activation, dynamic compression of the brachial plexus. CASE PRESENTATION: In the present study, we report about a 32-year-old male caucasian patient with weakness in radial deviation of his left hand...
