Abstract
Exercise rehabilitation has been proposed for the management of Neurogenic Thoracic Outlet Syndrome (NTOS). To date there have been no reviews of the literature regarding exercise rehabilitation for NTOS and their proposed clinical rationale. Understanding various exercise protocols and their clinical rationale may help guide rehabilitation clinicians in their exercise selection when managing NTOS. A scoping review was conducted on exercise rehabilitation for NTOS from inception to March 2021 in the PubMed database. Forty-seven articles consisting of literature reviews, non-randomized control trials, prospective and retrospective cohort studies, case series, case studies and clinical commentaries met the inclusion criteria. This scoping review provides a broad overview of the most common exercise protocols that have been published and examines the purported clinical rationale utilized in the management of NTOS.

Howard M, Jones M, Clarkson R, Donaldson O. Pectoralis minor syndrome: diagnosis with Botulinum injection and treatment with tenotomy - a prospective case series. Shoulder Elbow 2022; 14:157-161. [PMID: 35265181 PMCID: PMC8899325 DOI: 10.1177/1758573220968454] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/13/2020] [Revised: 10/02/2020] [Accepted: 10/03/2020] [Indexed: 11/16/2022]
Abstract
BACKGROUND Pectoralis minor syndrome involves pain, paraesthesia and weakness in the arm due to compression of the brachial plexus passing beneath pectoralis minor; this paper reports the results of a single centre's treatment pathway in affected patients. METHODS During a four-year period, patients exhibiting symptoms of pectoralis minor syndrome without significant improvement following physiotherapy proceeded to Botulinum injection. Those with good response to injection but subsequent recurrence of symptoms were offered pectoralis minor tenotomy. Oxford shoulder Scores were collected at baseline and after interventions. RESULTS Twenty-one patients received Botulinum injection; at six weeks following injection, mean change in Oxford Shoulder Score was +12.4, with only one patient reporting a worsening of symptoms. Of the 17 patients with clinically significant response to injection, 12 have subsequently undergone tenotomy; three months following tenotomy, mean change in Oxford Shoulder Score from baseline was +22.3. Improvement was maintained in all patients at prolonged follow-up (average 20 months post-tenotomy). DISCUSSION This pathway has shown to be extremely effective in patients not responding to first-line treatment for pectoralis minor syndrome, with 85% of patients post-injection and 100% of patients post-tenotomy showing significant (greater than published minimal clinically important difference value of six points) improvements in Oxford Shoulder Score, maintained at follow-up.

Abstract
ABSTRACT The painful tingling arm is a common presenting complaint for the musculoskeletal physician. The differential diagnosis for upper-extremity pain associated with paresthesias will be the focus of this review. Symptoms are often neurologic in etiology, originating from the spinal cord, nerve root(s), brachial plexus, or peripheral nerve(s). Localizing the pathology starts with a comprehensive understanding of neuromuscular anatomy. It also is imperative to understand the function of these respective structures. The differential diagnosis can be narrowed with a thorough history, including an assessment of sport-specific risk factors, along with a comprehensive physical examination and functional assessment. It is important to determine the sensory distribution of the patient's symptoms. If weakness also is present, the affected muscles must be identified. While the diagnosis can often be made clinically, electrodiagnostics, magnetic resonance imaging, and ultrasound can be used as needed for confirmation and more specific localization. Nonneurologic structures also may be causative or contributory to the patient's symptoms and also should be considered.

Abstract
OBJECTIVE Thoracic outlet syndrome is caused by the compression of blood vessels and nerves leading to the upper limbs; the level of functional discomfort in activities of daily living can be significant. This discomfort has been evaluated using a variety of nonspecific scales, prompting the development a specific self-questionnaire ("Functional Evaluation in Thoracic Outlet Syndrome). Here, the scale's test-retest reliability, sensitivity to change, and criterion validity were assessed. DESIGN Between May 2015 and July 2017, a total of 37 patients were assessed during an intensive rehabilitation program. The Functional Evaluation in Thoracic Outlet Syndrome self-questionnaire comprises 16 items rated on a 4-point scale: impossible, major discomfort, moderate discomfort, or no difficulty. A total score is then calculated and the usual level of discomfort is rated on a numerical scale. The questionnaire was completed on day (D)1, D2, and the day of discharge. RESULTS The questionnaire showed very good test-retest reliability, with an overall correlation coefficient above 0.91. The overall score was highly sensitive to change, with a significant median improvement (-5.89) between D1 and discharge (P < 0.001). Of the 16 items, 9 showed significant scalability in their individual sensitivity to change. The criterion validity was moderate: the coefficient for the correlation with the numerical scale was 0.68 on D1 (P < 0.001), 0.55 on D2 (P < 0.001), and 0.69 at discharge (P < 0.001). CONCLUSIONS The Functional Evaluation in Thoracic Outlet Syndrome self-questionnaire is a quick, simple way of assessing the impact of thoracic outlet syndrome on activities of daily living. The overall score and most of the items displayed good reproducibility and sensitivity to change.

Abstract
Objective To describe a case of nerve kinking correlating with surgical findings in neurogenic thoracic outlet syndrome in a patient with history of brachial neuritis. Thoracic outlet syndrome and brachial neuritis are briefly reviewed. Case report A 32-year-old woman with a history of bilateral brachial neuritis presented with paraesthesias in her hand when abducting her shoulder to 45° or higher. A kink in the superior trunk of the brachial plexus, as well as asymmetrically narrowed costoclavicular space, was found on magnetic resonance imaging with the shoulder abducted. Conservative measures failed, leading to partial anterior scalenectomy and neurolysis, which led to improvement in her symptoms. Conclusion Anatomical variations in combination with biomechanical changes after brachial neuritis can be associated with neurogenic thoracic outlet syndrome.

Abstract
Background: Thoracic outlet syndrome (TOS) is a complex entity resulting in neurogenic or vascular manifestations. A wide array of procedures has evolved, each with its own benefits and drawbacks. The authors hypothesized that treatment of TOS with first rib resection (FRR) may lead to increased complication rates. Methods: A retrospective case control study was performed on the basis of the National Surgical Quality Improvement Program database from 2005 to 2014. All cases involving the operative treatment of TOS were extracted. Primary outcomes included surgical and medical complications. Analyses were primarily stratified by FRR and secondarily by other procedure types. Results: A total of 1853 patients met inclusion criteria. The most common procedures were FRR (64.0%), anterior scalenectomy with cervical rib resection (32.9%), brachial plexus decompression (27.2%), and anterior scalenectomy without cervical rib resection (AS, 8.9%). Factors associated with increased medical complications included American Society of Anesthesiologists (ASA) classification of 3 or greater and increased operative time. The presence or absence of FRR did not influence complication rates. Conclusions: FRR is not associated with an increased risk of medical or surgical complications. Medical complications are associated with increased ASA scores and longer operative time.

Abstract
Circumscapular pain is a frequent complaint in clinical practice. The dorsal scapular and long thoracic nerves course through the neck, where they may become entrapped between or within adjacent scalene muscles. Additionally, a high frequency of brachial plexus "piercing" variants have recently been documented, and it is unclear how they influence branching patterns distally along the brachial plexus. In the project reported here we strived to identify and quantify variations in dorsal scapular nerve and long thoracic nerve secondary to brachial plexus piercing variation. Ninety brachial plexuses from human cadavers (45 female/45 male) were evaluated to identify nerve branching patterns, specifically piercing versus non-piercing variants in the brachial plexus roots and nerves. Anatomical entrapment of the dorsal scapular nerve and long thoracic nerve was found in high frequencies (60.8% and 44.6%, respectively). Anomalous brachial plexus piercing variants were associated with higher frequencies of distal nerve branches also coursing through the scalene musculature, and there was a statistically significant correlation between brachial plexus and long thoracic nerve piercings (p = 0.027). Anatomical entrapment of nerves within scalene musculature is common and may be causative factors for idiopathic circumscapular pain, dorsalgia, and dysfunction of scapulohumeral rhythm. This study revealed a link between anatomical arrangement of the brachial plexus and occurrence of long thoracic nerve entrapment, which may lead to a series of cascading neurologic effects in which affected individuals may suffer from increased incidence of thoracic outlet syndrome and long thoracic nerve entrapment resulting in additional symptoms of interscapular pain and compromised shoulder mobility.

Abstract
BACKGROUND/OBJECTIVE Sport-related vascular trauma is an important consequence of increased physical activity. Repetitive, high-intensity movements predispose athletes to vascular disease, including arterial pathology, by exerting increased pressure on neurovascular structures. This is an important source of morbidity in an otherwise young and healthy population. Arterial pathology associated with repetitive trauma is often misdiagnosed as musculoskeletal injury. This article increases awareness of sport-related arterial disease by reviewing the symptomatology, investigation, and treatment modalities of this pathology. In addition, prognostic outcomes specific to the athlete are discussed. RESULTS Arterial thoracic outlet syndrome and vascular quadrilateral space syndrome are associated with athletes involved in overhead throwing exercises. Sport-related arterial pathology of the lower limb include external iliac artery endofibrosis (EIAE), popliteal artery entrapment syndrome (PAES), and adductor canal syndrome. Vascular stress and kinking secondary to vessel tethering are important contributors to pathology in EIAE. Chronic exertional compartment syndrome must also be considered, presenting with clinical features similar to PAES. In addition, athletes are predisposed to blunt mechanical trauma. Hypothenar hammer syndrome is one such example, contributing to a high burden of morbidity in this population. CONCLUSIONS In arterial thoracic outlet syndrome and vascular quadrilateral space syndrome, surgery is advocated in symptomatic individuals, with postoperative outcomes favorable for the athlete. Acute limb ischemia may occur as a result of secondary thrombosis or embolization, often without preceding claudication. PAES and adductor canal syndrome are associated with functional entrapment in the athlete, secondary to muscular hypertrophy. Surgical exploration may be indicated. Poorer outcomes are noted when this process is associated with vascular reconstruction. Surgical treatment of EIAE follows failure of conservative management, with limited data available on postoperative prognosis. Investigations for all these conditions should be targeted based on clinical suspicion. A delay in diagnosis can have severe consequences on return to competition in these high-functioning individuals.

Abstract
We report a rare case of multiple hereditary exostosis where patient presented with bilateral base of neck exostoses with concurrent compression of brachial plexus and subclavian artery and vein. The patient was a young 26-year-old woman with chief complaints of pain in the left upper extremity, paresthesia in the left ring and little finger, and weakness in hand movement and grip. On referral, history, physical examination, radiological imaging, and electrodiagnostic tests evaluated the patient. Due to severe pain and disability in performing routine activities, surgical intervention was necessary. In the current case, the patient had thoracic outlet syndrome with concomitant venous, arterial, and neurogenic sub types. Radial pulse returned and pain associated with brachial plexus compression was resolved after the surgery.

Abstract
Background Surgical treatment of thoracic outlet syndrome (TOS) is necessary when non-surgical treatments fail. Complications of surgical procedures vary from short-term post-surgical pain to permanent disability. The outcome of TOS surgery is affected by the visibility during the operation. In this study, we have compared the complications arising during the supraclavicular and the transaxillary approaches to determine the appropriate approach for TOS surgery. Methods In this study, 448 patients with symptoms of TOS were assessed. The male-to-female ratio was approximately 1:4, and the mean age was 34.5 years. Overall, 102 operations were performed, including unilateral, bilateral, and reoperations, and the patients were retrospectively evaluated. Of the 102 patients, 63 underwent the supraclavicular approach, 32 underwent the transaxillary approach, and 7 underwent the transaxillary approach followed by the supraclavicular approach. Complications were evaluated over 24 months. Results The prevalence of pneumothorax, hemothorax, and vessel injuries in the transaxillary and the supraclavicular approaches was equal. We found more permanent and transient brachial plexus injuries in the case of the transaxillary approach than in the case of the supraclavicular approach, but the difference was not statistically significant. Persistent pain and symptoms were significantly more common in patients who underwent the transaxillary approach (p<0.05). Conclusion The supraclavicular approach seems to be the more effective technique of the two because it offers the surgeon better access to the brachial plexus and a direct view. This approach for a TOS operation offers a better surgical outcome and lower reoperation rates than the transaxillary method. Our results showed the supraclavicular approach to be the preferred method for TOS operations.

Abstract
Compression of the dorsal scapular nerve (DSN) is associated with pain in the upper extremity and back. Even though entrapment of the DSN within the middle scalene muscle is typically the primary cause of pain, it is still easily missed during diagnosis. The purpose of this study was to document the DSN's anatomy and measure the oblique course it takes with regard to the middle scalene muscle. From 20 embalmed adult cadavers, 23 DSNs were documented regarding the nerve's spinal root origin, anatomical route, and muscular innervations. A transverse plane through the laryngeal prominence was established to measure the distance of the DSN from this plane as it enters, crosses, and exits the middle scalene muscle. Approximately 70% of the DSNs originated from C5, with 74% piercing the middle scalene muscle. About 48% of the DSNs supplied the levator scapulae muscle only and 52% innervated both the levator scapulae and rhomboid muscles. The average distances from a transverse plane at the laryngeal prominence where the DSN entered, crossed, and exited the middle scalene muscle were 1.50 cm, 1.79 cm, and 2.08 cm, respectively. Our goal is to help improve clinicians' ability to locate the site of DSN entrapment so that appropriate management can be implemented.

Abstract
OBJECTIVE The aim of this study was to establish reference values for the width of the interval between the anterior and middle scalene muscles using ultrasonography during varying degrees of glenohumeral joint (GH) abduction. Reliability and body mass index (BMI) data were also assessed. METHODS Interscalene triangles of asymptomatic participants were scanned bilaterally in the transverse plane. Images were obtained at 0°, 90°, and 150° of GH abduction with the participant seated. Width measurements were taken between the anterior and middle scalene muscle borders by bisecting the C6 nerve root as it passed superficial to the posterior tubercle of the C7 transverse process. Intra- and interexaminer reliability and BMI correlation were studied. Statistical significance was defined as P ≤ .05. RESULTS Images of 42 scalene intervals were included from 21 participants (11 female). Mean participant age was 25.3 ± 3.9 years; mean BMI was 25.4 ± 2.7 kg/m2. Scalene interval measurements at 0°, 90°, and 150° of GH abduction were 4.5 ± 0.5 mm, 4.6 ± 0.5 mm, and 4.4 ± 0.7 mm, respectively, without a significant difference (P = .07). Intraexaminer reliability was excellent (0°: intraclass correlation coefficient [ICC] = 0.82; 90°: ICC = 0.89; 150°: ICC = 0.90). Interexaminer reliability was good to excellent (0°: ICC = 0.59; 90°: ICC = 0.85; 150°: ICC = 0.89). Body mass index was positively correlated only at 0° of GH abduction. CONCLUSIONS This study establishes previously unreported reference ultrasonography values for the width of the scalene interval. Intraexaminer reliability was excellent at all glenohumeral positions, and interexaminer reliability was determined to be good to excellent. Body mass index was positively correlated only at 0° of GH abduction.

Abstract
There are currently many disease-specific groups on Facebook in which patients may take an active part (Greene, Choudhry, Kilabuk, & Shrank, 2011). Although uses and gratifications of patient-disease groups have begun to be identified for chronic diseases, rare diseases have been omitted, even though they collectively affect roughly 30 million people in the United States and 350 million people worldwide. This study is a content analysis of one Facebook rare disease patient group, the Thoracic Outlet Syndrome (TOS) Awareness group. All wall posts were recorded and content analyzed for cognitive and affective categories and subcategories between October 9, 2011 (date of site origin), and May 1, 2012. Analysis of cognitive needs indicated TOS patients used the site more to share information about their own TOS symptoms and journey with diagnosis than to seek information. Analysis of affective needs found patients were more likely to use the site to give support and encouragement to others than to express concerns and complaints. The complaints they did express were primarily related to their frustration with the general medical community's perceived inability to diagnose and understand their disease or to question a specific doctor's diagnosis/recommendation. Results point to needs specific to TOS patients that uses and gratifications research can help clarify.

Abstract
Rare disease patients are the predominant group of patients who are now connecting online to patient support groups, yet research on their uses of support groups has received little attention. This is a content analysis of three vascular diseases of differing degrees of rarity. Wall posts from Facebook patient support groups for May Thurner syndrome, thoracic outlet syndrome, and superior mesenteric artery syndrome were analyzed over a period of two years. Using Uses and Gratifications as the theoretical framework, the study purpose was to assess how variations in health condition and rarity of condition affect online support group user needs. Results indicated common main cognitive and affective uses across conditions, indicating a consistent pattern of needs communicated by all patients. However, there were nuanced differences in subcategories of cognitive and affective uses between the most and least rare disorders, which inform areas for tailored support mechanisms. Additionally, these vascular patients used their respective support groups primarily for cognitive reasons, especially for the rarest conditions, which informs of basic medical informational needs these patients face related to tests, treatment, surgery, and diagnoses.

Streit RS. NTOS symptoms and mobility: a case study on neurogenic thoracic outlet syndrome involving massage therapy. J Bodyw Mov Ther 2013; 18:42-8. [PMID: 24411148 DOI: 10.1016/j.jbmt.2013.04.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2013] [Revised: 04/10/2013] [Accepted: 04/11/2013] [Indexed: 10/26/2022]
Abstract
Neurogenic thoracic outlet syndrome (NTOS) is a neuromuscular condition affecting brachial plexus functionality. NTOS is characterized by paresthesia, pain, muscle fatigue, and restricted mobility in the upper extremity. This study quantified massage therapy's possible contribution to treatment of NTOS. A 24-year-old female with NTOS received eight treatments over 35 days. Treatment included myofascial release, trigger point therapy, cross fiber friction, muscle stripping, and gentle passive stretching. Abduction and lateral rotation at the glenohumeral (GH joint) assessments measured range of motion (ROM). A resisted muscle test evaluated upper extremity strength. The client rated symptoms daily via a visual analog scale (VAS). Findings showed improvement in ROM at the GH joint. VAS ratings revealed a reduction in muscle weakness, pain, numbness, and 'paresthesia'. Results suggest massage may be useful as part of a broad approach to managing NTOS symptoms and improving mobility.

Abstract
The posterior triangle of the neck is an area of the body frequently visited by regional anesthesiologists, acute and chronic pain physicians, surgeons of all disciplines, and diagnosticians. It houses the entire brachial plexus from the roots to the divisions, the scalene muscles, the cervical sympathetic ganglions, the major blood vessels to and from the brain, the neuroforamina and various other structures of more or less importance to these physicians. Ultrasound (US) offers a handy visual tool for these structures to be viewed in real time and, therefore, its popularity and the need to understand it. We will discuss pertinent clinical anatomy of the neck and offer a basic visual explanation of the often-difficult two-dimensional (2-D) images seen with US.
