Abstract
Botulinum toxin (BTX) injections into the musculature surrounding the brachial plexus have been examined as a potential treatment for neurogenic thoracic outlet syndrome (nTOS). This systematic review identified 15 publications, of which one was a randomized controlled trial. BTX injections performed with ultrasound or electromyographic guidance, and with the inclusion of the pectoralis minor muscle, in addition to the anterior and/or middle scalenes, tended to provide greater symptom improvement and may predict response to first rib resection. Importantly, most studies were of low quality; thus, the results should be interpreted with caution. Further high-quality studies are needed to confirm these findings.

Abstract
BACKGROUND Thoracic outlet syndrome (TOS) remains a rare diagnosis but is being recognized as a cause of upper extremity dysfunction in professional baseball players. PURPOSE/HYPOTHESIS The purpose was to determine performance and return-to-play (RTP) outcomes in professional baseball players after surgical treatment of TOS. The hypothesis was that there would be a high RTP rate in professional baseball players after TOS surgery with no statistical differences in performance between pitchers who had TOS surgery and matched controls. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS All professional baseball players who underwent surgical treatment of TOS between 2010 and 2017 were identified using the Major League Baseball Health and Injury Tracking System database. Demographic and performance data (before and after surgery) for each player were recorded. Performance variables were then compared between players who underwent TOS surgery and matched controls. The matching criteria were no history of previous surgeries on affected arm, age at time of surgery, throwing side, level of play (Major or Minor League Baseball), and years of experience playing professional baseball. RESULTS Overall, 52 players underwent surgery for TOS, of whom 46 (88%) were pitchers. The type of TOS was neurogenic in 69% and venous in 29%. One player had arterial TOS. After TOS surgery, 79% of players returned to play at the same or higher level (RTSP) by 9.5 months and played ≥3 years after surgery. No differences were found in RTSP rate based on the type of TOS. No statistical difference was found in RTP rates between major and minor league players. Pitchers had a 76% RTSP, which was similar to the natural attrition for control pitchers (P = .874). After TOS surgery, pitchers saw a decline in several performance metrics, but these declines were not different from those of control pitchers, indicating that the decline in performance after TOS surgery was no faster than is seen in healthy professional pitchers as they age. CONCLUSION The rate of RTSP after surgery for TOS in professional baseball players was 79%. There was no difference in RTP based on the type of TOS. Pitchers who underwent surgery for TOS had no significant differences in pitching performance metrics after surgery compared with matched controls.

Abstract
Background We aimed to retrospectively compare the clinical outcomes of endoscopy-assisted first-rib resection for thoracic outlet syndrome (TOS) between overhead athletes and nonathletes and investigate the return to same-level sports rate in overhead athletes. Methods We retrospectively reviewed 181 cases with TOS (75 women, 106 men; mean age, 28.4 years; range, 12-57 years) who underwent endoscopy-assisted first-rib resection. We divided into two groups: 79 overhead athletes and 102 nonathletes groups. A transaxillary approach for first-rib resection and neurovascular decompression was performed under magnified visualization. Endoscopic findings related to the neurovascular bundle, interscalene distance, and scalene muscle were evaluated intraoperatively. We assessed the Roos and Disability of the Arm, Shoulder, and Hand scores, return to same-level sports rate, and ball velocity. Results Overhead athletes were significantly more likely to be men, younger, used the dominant side more frequently, and have a larger physique, more shoulder and elbow pain, and shorter symptom duration. The outcomes of the Roos score revealed significant differences in excellent or good results between overhead athletes (91.1%) and nonathletes (62.8%). The two groups significantly differed in preoperative and postoperative Disability of the Arm, Shoulder, and Hand and recovery rate scores (P = .007, < .001, < .001). Conclusion Overhead athletes with TOS were more likely to be men, younger, dominant side more frequently, and have more shoulder and elbow pain, and a shorter symptom duration. Endoscopy-assisted transaxillary first-rib resection and neurolysis provided superior clinical outcomes in overhead athletes with TOS compared with nonathletes and a high return-to-same-level-play rate in sports.

Abstract
Pectoralis minor syndrome (PMS) and quadrilateral space syndrome (QSS) are uncommon neurovascular compression disorders affecting the upper extremity. PMS involves compression under the pectoralis minor muscle, and QSS results from compression in the quadrilateral space-both are classically observed in overhead-motion athletes. Diagnosing PMS and QSS may be challenging due to variable presentations and similarities with other, more common, upper-limb pathologies. Although there is no gold standard diagnostic, local analgesic muscle-block response in a patient with the appropriate clinical context is often all that is required for an accurate diagnosis after excluding more common etiologies. Treatment ranges from conservative physical therapy to decompressive surgery, which is reserved for refractory cases or severe, acute vascular presentations. Decompression generally yields favorable outcomes, with most patients experiencing significant relief and restored baseline function. In conclusion, PMS and QSS, although rare, can cause debilitating upper-extremity symptoms; accurate diagnosis and appropriate treatment offer excellent outcomes, alleviating pain and disability.

Abstract
The diagnosis and clinical features of thoracic outlet syndrome have long confounded clinicians, owing to heterogeneity in symptom presentation and many overlapping competing diagnoses that are "more common." Despite the advent and prevalence of high-resolution imaging, along with the increasing awareness of the syndrome itself, misdiagnoses and untimely diagnoses can result in significant patient morbidity. The authors aimed to summarize the current concepts in the clinical features and diagnosis of thoracic outlet syndrome.

Abstract
The physical demands of sports can place patients at elevated risk of use-related pathologies, including thoracic outlet syndrome (TOS). Overhead athletes in particular (eg, baseball and football players, swimmers, divers, and weightlifters) often subject their subclavian vessels and brachial plexuses to repetitive trauma, resulting in venous effort thrombosis, arterial occlusions, brachial plexopathy, and more. This patient population is at higher risk for Paget-Schroetter syndrome, or effort thrombosis, although neurogenic TOS (nTOS) is still the predominant form of the disease among all groups. First-rib resection is almost always recommended for vascular TOS in a young, active population, although a surgical benefit for patients with nTOS is less clear. Practitioners specializing in upper extremity disorders should take care to differentiate TOS from other repetitive use-related disorders, including shoulder orthopedic injuries and nerve entrapments at other areas of the neck and arm, as TOS is usually a diagnosis of exclusion. For nTOS, physical therapy is a cornerstone of diagnosis, along with response to injections. Most patients first undergo some period of nonoperative management with intense physical therapy and training before proceeding with rib resection. It is particularly essential for ensuring that athletes can return to their baselines of flexibility, strength, and stamina in the upper extremity. Botulinum toxin and lidocaine injections in the anterior scalene muscle might predict which patients will likely benefit from first-rib resection. Athletes are usually satisfied with their decisions to undergo first-rib resection, although the risk of rare but potentially career- or life-threatening complications, such as brachial plexus injury or subclavian vessel injury, must be considered. Frequently, they are able to return to the same or a higher level of play after full recovery.

Abstract
Neurogenic thoracic outlet syndrome is a challenging condition to diagnose and treat, often precipitated by the triad of repetitive overhead activity, pectoralis minor contracture, and scapular dyskinesia. The resultant protracted scapular posture creates gradual repetitive traction injury of the suprascapular nerve via tethering at the suprascapular notch and decreases the volume of the brachial plexus cords and axillary vessels in the retropectoralis minor space. A stepwise and exhaustive diagnostic protocol is essential to exclude alternate pathologies and confirm the diagnosis of this dynamic pathologic process. Ultrasound-guided injections of local anesthetic or botulinum toxin are a key factor in confirming the diagnosis and prognosticating potential response from surgical release. In patients who fail over 6 months of supervised physical therapy aimed at correcting scapular posture and stretching of the pectoralis minor, arthroscopic surgical release is indicated. We present our diagnostic algorithm and technique for arthroscopic suprascapular neurolysis, pectoralis minor release, brachial plexus neurolysis, and infraclavicular thoracic outlet decompression.

Abstract
OBJECTIVE Scalene blocks are part of both the diagnostic and treatment algorithm for patients presenting with symptoms of neurogenic thoracic outlet syndrome (nTOS). However, there is a paucity of data on the utility of scalene botulinum toxin injection (BTI) before surgical decompression. We sought to determine the impact of BTI with and without surgery at a multidisciplinary referral center. DESIGN Retrospective cohort study. SETTING Single institution tertiary academic center, 2011 to 2020. PATIENTS Seventy-seven consecutive patients. INTERVENTIONS Scalene muscle BTI for nTOS with or without surgical decompression. MAIN OUTCOME MEASURES Pain relief and Quick Disability of the Arm, Shoulder and Hand (QDASH) score. RESULTS Seventy-seven patients, with a mean age of 31.4 years, had BTI for symptoms of nTOS. All patients underwent pretreatment physical therapy through the Edgelow protocol for a mean duration of 3.4 months. However, 72.7% had dynamic vascular compression on duplex ultrasound with provocative maneuvers and 85.7% had a positive physical examination finding. After BTI, 77.9% reported subjective relief, confirmed by an improved QDASH disability score. Thirty-one patients (40.3%) then went on to have further persistent symptoms and proceeded with first rib resection. After BTI + Surgery, 96.8% reported symptomatic relief and had a median QDASH score improvement of 21 (range: 10-40), with all reaching minimal clinically important differences in the QDASH score after combination therapy. CONCLUSIONS In this reported series of chemodenervation in patients with nTOS, BTI is helpful in alleviating symptoms before definitive surgical decompression. BTI followed by first rib resection provides additional symptom improvement over BTI alone.

Abstract
Compressive pathology in the supraclavicular and infraclavicular fossae is broadly termed "thoracic outlet syndrome," with the large majority being neurogenic in nature. These are challenging conditions for patients and physicians and require robust knowledge of thoracic outlet anatomy and scapulothoracic kinematics to elucidate neurogenic versus vascular disorders. The combination of repetitive overhead activity and scapular dyskinesia leads to contracture of the scalene muscles, subclavius, and pectoralis minor, creating a chronically distalized and protracted scapular posture. This decreases the volume of the scalene triangle, costoclavicular space, and retropectoralis minor space, with resultant compression of the brachial plexus causing neurogenic thoracic outlet syndrome. This pathologic cascade leading to neurogenic thoracic outlet syndrome is termed pectoralis minor syndrome when primary symptoms localize to the infraclavicular area. Making the correct diagnosis is challenging and requires the combination of complete history, physical examination, advanced imaging, and ultrasound-guided injections. Most patients improve with nonsurgical treatment incorporating pectoralis minor stretching and periscapular and postural retraining. Surgical decompression of the thoracic outlet is reserved for compliant patients who fail nonsurgical management and respond favorably to targeted injections. In addition to prior exclusively open procedures with supraclavicular, infraclavicular, and/or transaxillary approaches, new minimally invasive and targeted endoscopic techniques have been developed over the past decade. They involve the endoscopic release of the pectoralis minor tendon, with additional suprascapular nerve release, brachial plexus neurolysis, and subclavius and interscalene release depending on the preoperative work-up.

Abstract
A positive response to scalene muscle block (SMB) is an important indication for the diagnosis of thoracic outlet syndrome. Lidocaine injection is commonly used in clinical practice in SMB, although there have been some cases of misdiagnosis. Botulinum toxin A (BTX-A) is one of the therapeutic agents in SMB, but whether it is also indicated for SMB diagnosis is controversial. To evaluate the muscle block efficiency of these two drugs, the contraction strength was repeatedly recorded on tibialis anterior muscle in rats. It was found that at a safe dosage, 2% lidocaine performed best at 40 μL, but it still exhibits an unsatisfactory partial blocking efficiency. Moreover, neither lidocaine injection in combination with epinephrine or dexamethasone nor multiple locations injection could improve the blocking efficiency. On the other hand, injections of 3, 6, and 12 U/kg BTX-A all showed almost complete muscle block. Gait analysis showed that antagonistic gastrocnemius muscle, responsible for heel rising, was paralyzed for nonspecific blockage in the 12 U/kg BTX-A group, but not in the 3 U/kg or 6 U/kg BTX-A group. Cleaved synaptosomal associated protein 25 (c-SNAP 25) was stained to test the transportation of BTX-A, and was additionally observed in the peripheral muscles in 6 and 12 U/kg groups. c-SNAP 25, however, was barely detectable in the spinal cord after BTX-A administration. Therefore, our results suggest that low dosage of BTX-A may be a promising option for the diagnostic SMB of thoracic outlet syndrome. SIGNIFICANCE STATEMENT: Muscle block is important for the diagnosis and treatment of thoracic outlet syndrome and commonly performed with lidocaine. However, misdiagnosis was observed sometimes. Here, we found that intramuscular injection of optimal dosage lidocaine only partially blocked the muscle contraction in rats, whereas low-dosage botulinum toxin, barely used in diagnostic block, showed almost complete block without affecting the central nervous system. This study suggests that botulinum toxin might be more suitable for muscle block than lidocaine in clinical practice.

Abstract
Thoracic outlet syndrome is an umbrella term for compressive pathologies in the supraclavicular and infraclavicular fossae, with the vast majority being neurogenic in nature. These compressive neuropathies, such as pectoralis minor syndrome, can be challenging problems for both patients and physicians. Robust understanding of thoracic outlet anatomy and scapulothoracic biomechanics are necessary to distinguish neurogenic vs. vascular disorders and properly diagnose affected patients. Repetitive overhead activity, particularly when combined with scapular dyskinesia, leads to pectoralis minor shortening, decreased volume of the retropectoralis minor space, and subsequent brachial plexus compression causing neurogenic thoracic outlet syndrome. Combining a thorough history, physical examination, and diagnostic modalities including ultrasound-guided injections are necessary to arrive at the correct diagnosis. Rigorous attention must be paid to rule out alternate etiologies such as peripheral neuropathies, vascular disorders, cervical radiculopathy, and space-occupying lesions. Initial nonoperative treatment with pectoralis minor stretching, as well as periscapular and postural retraining, is successful in the majority of patients. For patients that fail nonoperative management, surgical release of the pectoralis minor may be performed through a variety of approaches. Both open and arthroscopic pectoralis minor release may be performed safely with effective resolution of neurogenic symptoms. When further indicated by the preoperative workup, this can be combined with suprascapular nerve release and brachial plexus neurolysis for complete infraclavicular thoracic outlet decompression.

Abstract
Thoracic outlet syndrome (TOS) is a rare and heterogeneous syndrome secondary to a compression of the neurovascular bundle in the thoracic outlet area. Muscle hypertrophy is recognized to induce vascular or neurogenic compression, especially in sports involving upper-arm solicitation. Athletes represent a distinctive population because of a specific management due to an ambitious objective, which is returning to high-level competition. We evaluated the scientific literature available for the management of TOS in athletes. Article research extended to March 2021 without other restriction concerning the date of articles publication. The search was performed independently by two assessors. A first preselection based on the article titles was produced, regarding their availability in English or French and a second preselection was produced after reading the abstracts. In case of doubt, a third assessor’s advice was asked. Case reports were selected only if the sport involved was documented, as well as the level of practice. Cohorts were included if data about the number and the sport level of athletes were detailed. Seventy-eight articles were selected including 40 case reports, 10 clinical studies and 28 reviews of literature. Baseball pitchers seem to be highly at risk of developing a TOS. The surgical management appears particularly frequent in this specific population. The prognosis of TOS in athletes seems to be better than in the general population, possibly due to their better physical condition and their younger age. Some studies showed interesting and encouraging results concerning return to previous sport level. Literature shows a strong link between TOS and certain sports. Unfortunately, this syndrome still lacks rigorous diagnostic criteria and management guidelines for athletes.

Abstract
Thoracic outlet syndrome is an important cause of shoulder pain and dysfunction due to compression of neurovascular structures as they traverse the thoracic outlet. Symptoms are most commonly due to compression of the brachial plexus called neurogenic thoracic outlet syndrome (nTOS). Throwing athletes are at increased risk of nTOS because of a variety of biomechanical factors. However, because nTOS symptoms are often nonspecific, delayed diagnosis is common. Neurogenic thoracic outlet largely remains a diagnosis of exclusion with advanced imaging ruling out vascular involvement and diagnostic injections gaining favor in helping localize sites of compression. Although rehabilitation alone may improve symptoms in some athletes, many require surgical treatment for long-term relief. This generally entails decompression of the thoracic outlet by some combination of muscle release, brachial plexus neurolysis, and first rib resection. Outcomes tend to be successful in athletes with most achieving resolution of symptoms and return to athletic activity. NTOS is an important cause of shoulder pain and dysfunction in throwing athletes. The history and physical examination should focus on activities that exacerbate symptoms. Treatment of nTOS generally requires surgical intervention and allows throwing athletes to return to sport.

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
Peripheral nerve injuries in the upper extremities may be common in throwing athletes as the throwing motion places extreme stress on the dominant arm. The combination of extreme stress along with repetitive microtrauma from throwing uniquely places the throwing athlete at elevated risk of upper extremity peripheral nerve injury. However, because symptoms can be non-specific and frequent co-exist with pathology in the upper extremity, the diagnosis of peripheral nerve injury is often delayed. Diagnosis of peripheral nerve injuries may require a combination of history and physical exam, diagnostic imaging, electrodiagnostic testing, and diagnostic ultrasound guided injections. The primary management should include physical therapy focusing on throwing mechanics and kinetic chain evaluation. However, some athletes require surgical intervention if symptoms do not improve with conservative management. The purpose of this focused narrative review is to highlight upper extremity peripheral neuropathies reported in throwing athletes and to provide an overview of the appropriate clinical diagnosis and management of the throwing athlete with a peripheral nerve injury.

Abstract
ABSTRACT Neurogenic thoracic outlet syndrome (NTOS) is an etiologically and clinically diverse disorder caused by compression of the brachial plexus traversing the thoracic outlet. Athletes who perform repetitive overhead activities are at risk of developing NTOS with sport-specific symptoms. This article reviews the controversial NTOS nomenclature, common sites of anatomic compression, and red flag symptoms that require immediate intervention. It also reviews the congenital, traumatic, and functional etiologies of NTOS, with a discussion of the differential diagnosis, diagnostic criteria, and workup for NTOS. Nonsurgical treatment is highlighted with an emphasis on thoracic outlet syndrome-specific physical therapy and updates on injection options and ultrasound guided hydrodissection. This article compares nonsurgical versus surgical functional outcome data with an emphasis on athletes with NTOS. Functional assessment tools and performance metrics for athletes are reviewed, as well as return to sport considerations.

Abstract
Purpose To assess the feasibility, safety, and clinical outcomes of an endoscopic-assisted transaxillary approach of first rib resection for thoracic outlet syndrome (TOS) and to compare the differences in demographic and clinical data between satisfactory and unsatisfactory outcomes using this approach. Methods We retrospectively identified patients who underwent endoscopic-assisted first rib partial resection. A transaxillary approach for the first rib resection and neurovascular decompression were undertaken under magnified visualization. Endoscopic classification of neurovascular bundle (NVB) patterns and interscalene distance (ISD) between anterior and middle scalene muscles were evaluated intraoperatively. We assessed the Roos and DASH scores. Results We reviewed 131 cases of TOS (48 women and 83 men; mean age 26.2 years; range 12 to 57). Roos classification revealed 80.2% excellent or good results. DASH scores improved significantly from 40.7 ± 20.0 to 15.7 ± 19.6 (P < .001). The complication rate was low (5.3%), with 4 pneumothorax and 3 other complications. Intraoperative NVB classification revealed 30 cases of parallel type, in which the artery and nerve travel in parallel; 69 oblique types, and 30 vertical types, in which the nerve was completely behind the middle scalene muscle or abnormal band. The ISD was narrower (5.4 ± 3.6 mm) than in previous cadaveric studies. The ISD in the parallel patterns was wider than that in the vertical patterns. In the satisfactory group, we found a significantly larger number of men, younger patients, athletes, and patients with a lower preoperative DASH score. Conclusions An endoscopic-assisted transaxillary approach for first rib resection in TOS provides an excellent magnified visualization, safely allowing sufficient decompression of the neurovascular bundle and satisfactory surgical outcomes. Younger male athletes with TOS may be better candidates for this procedure. Level of Evidence IV, therapeutic case series.

Abstract
BACKGROUND Thoracic outlet syndrome (TOS) refers to a constellation of compressive problems that occur at the thoracic outlet. TOS has been recognized since the 19th century, and the "modern" era of treatment, especially for neurogenic TOS, dates from at least the 1970s. Despite this, however, the incidence and prevalence of these syndromes are almost completely unknown. To attempt to answer this fundamental question, we established a prospective database of all patients who presented to our clinic with a diagnosis of potential TOS, as described below. METHODS We established a database of all patients referred to our clinic from July 1, 2014 to May 2018. All subjective data, the tentative diagnosis, and plan at the time of the office visit were prospectively recorded. For patients with neurogenic TOS (NTOS), a standardized workup sheet was used based on the Society for Vascular Surgery's recently published reporting standards document. For patients with venous TOS (VTOS), diagnosis was made by clinical examination and ultrasound, and for those with arterial TOS (ATOS), by clinical examination, ultrasound, and cross-sectional imaging when needed. RESULTS From July 1, 2014, to May 1, 2018, 526 patients were referred to our institution with a diagnosis of possible TOS. Of these, 432 (82%) were referred with symptoms suggestive of NTOS, 84 (16%) with symptoms suggestive of VTOS, and 10 (2%) with findings and/or symptoms suggestive of ATOS. NTOS: After evaluation as per the algorithm previously mentioned, 234 patients (54%) were judged high suspicion for NTOS, 126 (30%) moderate suspicion, and 72 (17%) low suspicion; 360 (83%) of those originally referred were felt to potentially have NTOS. Of the 84 patients with VTOS, 25 (30%) presented with acute Paget-Schroetter syndrome, 41 (48%) with subacute or chronic occlusion, and 18 (21%) with McCleery's syndrome. Finally, 8 of the 10 limbs had true ATOS; of these, 6 (75%) underwent decompression and repair and 2 (25%) endovascular intervention only. Based on referral assumptions and population density in our area, the incidence of NTOS seems to be between 2 and 3 cases per 100,000 people per year and that of VTOS between 0.5 and 1 per 100,000 people per year, ATOS being sporadic. The ratio of those with decent suspicion for NTOS and VTOS, respectively, is about 80:20, whereas that of those undergoing surgical decompression is about 75:25. CONCLUSIONS The rates of NTOS and VTOS, as aforementioned, are approximately 25 and 8 per year in a metropolitan area of 1,000,000, respectively. Although a rare disease, these numbers are not insignificant, although are much lower than prior estimates.

Abstract
PURPOSE OF REVIEW Neurovascular compression in the upper extremity is rare but can affect even those participating in high-level competitive athletics. To assess optimal approaches to treatment, in this review, we evaluate the current literature on neurovascular compressive syndromes affecting the upper extremity, with a special focus on the thoracic outlet syndrome (TOS). RECENT FINDINGS Neurovascular compression at the thoracic outlet can involve the brachial plexus, subclavian artery, or subclavian vein, each with distinct clinical manifestations. Neurogenic TOS is best treated with surgical decompression, if physical therapy has not improved symptoms. Venous TOS results in acute thrombosis superimposed on chronic venous compression. Treatment is best directed at early anticoagulation, catheter-directed thrombolysis, and surgical decompression, with most patients able to discontinue anticoagulation and return to high-level athletic activity. Arterial TOS is related to aneurysmal degeneration of the subclavian artery with distal embolization, leading to limb-threatening ischemia. This should be aggressively treated with surgery. Similar degenerative changes can occur in the axillary artery and its branches, leading to distal embolization. Prompt recognition of these potential sources of limb-threatening ischemia is critical to limb preservation. TOS includes rare but important conditions in the overhead athlete. Recent advances in physical therapy and image-guided diagnostic techniques have facilitated more accurate diagnosis. Surgical treatment remains the gold standard to maximize function or for limb preservation, and future research is needed to clarify optimal pain and physiotherapy regimens, as well as to examine novel approaches to neurovascular decompression.

Abstract
Background: Pectoralis minor syndrome (PMS) develops when the neurovascular bundle compression occurs at the retropectoralis minor space. It may occur due to repetitive overhead activities, traumatic incident, structural causes, myofascial pain syndrome in the pectoralis minor muscle, as well as spasticity of the pectoralis minor muscle. In patients with hemiplegia, adductor muscles along with pectoralis minor muscle spasticity may be present in the upper extremity.Objective: We report a 19-year-old male patient with spastic hemiparesis who was diagnosed with PMS due to spasticity of the pectoralis minor muscle.Method: Diagnosis of PMS was confirmed by Ultrasound-guided 4 cc 1% lidocaine injection to the right pectoralis minor muscle and Ultrasound-guided onabotulinum toxin A injection was performed. Stretching exercises to the pectoral muscles were also added to the rehabilitation program.Result: Complaints of the patient were controlled by botulinum toxin injections at 3-month intervals.Conclusion: It should be kept in mind that spasticity in the upper extremity may develop in the pectoralis minor muscle, and may cause pressure on the neurovascular structures. Ultrasound-guided botulinum toxin injections can be a safe and effective treatment for PMS in a patent with post stroke spastic hemiparesis.

Abstract
The diagnosis of thoracic outlet syndrome (TOS) has long been a controversial and challenging one. Despite common presentations with pain in the neck and upper extremity, there are a host of presenting patterns that can vary within and between the subdivisions of neurogenic, venous, and arterial TOS. Furthermore, there is a plethora of differential diagnoses, from peripheral compressive neuropathies, to intrinsic shoulder pathologies, to pathologies at the cervical spine. Depending on the subdivision of TOS suspected, diagnostic investigations are currently of varying importance, necessitating high dependence on good history taking and clinical examination. Investigations may add weight to a diagnosis suspected on clinical grounds and suggest an optimal management strategy, but in this changing field new developments may alter the role that diagnostic investigations play. In this article, we set out to summarise the diagnostic approach in cases of suspected TOS, including the importance of history taking, clinical examination, and the role of investigations at present, and highlight the developments in this field with respect to all subtypes. In the future, we hope that novel diagnostics may be able to stratify patients according to the exact compressive mechanism and thereby suggest more specific treatments and interventions.

Abstract
Neurogenic thoracic outlet syndrome is a widely recognized, yet controversial, syndrome. The lack of specific objective diagnostic modalities makes diagnosis difficult. This is compounded by a lack of agreed upon definitive criteria to confirm diagnosis. Recent efforts have been made to more clearly define a set of diagnostic criteria that will bring consistency to the diagnosis of neurogenic thoracic syndrome. Additionally, advancements have been made in the quality and techniques of various imaging modalities that may aid in providing more accurate diagnoses. Surgical decompression remains the mainstay of operative treatment; and minimally invasive techniques are currently in development to further minimize the risks of this procedure. Medical management continues to be refined to provide non-operative treatment modalities for certain patients, as well. The aim of the present work is to review these updates in the diagnosis and treatment of neurogenic thoracic outlet syndrome.
