Age as a Prognostic Factor of Spinal Nerve Injury after Selective Neck Dissection. J Pers Med 2023; 13:1082. [PMID: 37511696 PMCID: PMC10381417 DOI: 10.3390/jpm13071082] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 06/12/2023] [Accepted: 06/28/2023] [Indexed: 07/30/2023] Open
Abstract
OBJECTIVE The objective of this study is to investigate whether age is a significant risk factor for spinal nerve injury following selective neck dissection (SND) in patients with head and neck cancer. METHODS A retrospective cohort study was conducted on patients who had undergone SND for head and neck cancer at a tertiary hospital between 2020 and 2022. The primary outcome was the incidence of spinal nerve injury after SND. The secondary outcomes included the types and severity of spinal nerve injury and the impact of age on these outcomes. RESULTS A total of 78 patients were included in the study and subdivided into two groups. Two shoulder-specific questionnaires (the Shoulder Pain and Disability Index (SPADI) and the Shoulder Disability Questionnaire (SDQ)) were administered to assess shoulder morbidity postoperatively. Twelve patients showed shoulder impairment following surgery. We divided the sample into two age-based groups; the older group showed a higher rate of SAN injury and the younger group showed a lower rate of improvement over time. CONCLUSION This study suggests that age is a significant risk factor for spinal nerve injury following SND in patients with head and neck cancer. Older patients are more likely to experience spinal nerve injury after SND than younger patients. The findings of this study may help in the development of strategies to prevent spinal nerve injury in older patients undergoing SND for head and neck cancer.

Abstract
» Iatrogenic nerve injuries may occur after any intervention of the upper extremity. » Causes of iatrogenic nerve lesions include direct sharp or thermal injury, retraction, compression from implants or compartment syndrome, injection, patient positioning, radiation, and cast/splint application, among others. » Optimal treatment of iatrogenic peripheral nerve lesions relies on early and accurate diagnosis. » Advanced imaging modalities (e.g., ultrasound and magnetic resonance imaging) and electrodiagnostic studies aid and assist in preoperative planning. » Optimal treatment of iatrogenic injuries is situation-dependent and depends on the feasibility of direct repair, grafting, and functional transfers.

Abstract
UNLABELLED Spinal accessory nerve grafting requires identification of both nerve stumps in the scar tissue, which is sometimes difficult. We propose a direct nerve transfer using a fascicle from the posterior division of the upper trunk. We retrospectively reviewed 11 patients with trapezius palsy due to an iatrogenic injury of the spinal accessory nerve in nine cases. The mean age was 38 years (range 21-59). Preoperatively, patients showed shoulder weakness and limited range of motion. At a mean follow-up of 25 months, active shoulder abduction improvement averaged 57°. Trapezius muscle strength graded M4 or M5 in 10 cases and M3 in one case. No deltoid or triceps impairment was reported. Scapula kinematics was considered normal in seven patients. This technique gave satisfactory functional results and may be an alternative to spinal accessory nerve grafting for the management of trapezius palsies if direct repair is not feasible.

Abstract
Background Iatrogenic injuries to the spinal accessory nerve (SAN) are not uncommon during cervical lymph node biopsy. Many operative treatments for SAN injury in the posterior cervical triangle have been reported, but there are no guidelines regarding the choice between operative and nonoperative treatments. Because it is believed that the nerve seldom spontaneously regenerates, some articles suggest surgical intervention within 3 months from the nerve injury to achieve good postoperative results. However, we experienced a case of spontaneous accessory nerve recovery more than 3 months after accessory nerve injury. It is necessary to carefully exclude similar patients from unnecessary surgery. Case A 41-year-old woman underwent cervical lymph node biopsy at an otolaryngology clinic. She experienced pain across her neck and weakness of the shoulder in abduction just after the biopsy. Three months after the biopsy, her symptoms persisted and she was referred to our hospital for surgical treatment. On careful examination, we detected signs of accessory nerve regeneration. Consequently, we prescribed physical therapy and a rehabilitation program, including active and passive range-of-motion exercises of the shoulder and muscle strengthening exercises. Six months after the injury, there was a dramatic improvement of the trapezius muscle function and the patient became pain free. Discussion When the biopsy incision is more than one finger's breadth away from the normal course of the SAN, and when Tinel-like signs advance along the trapezius muscle over time, spontaneous SAN recovery can be anticipated.

Abstract
Objectives: A lesion in the spinal accessory nerve is typically iatrogenic: related to lymph node biopsy or excision. This injury may cause paralysis of the trapezius muscle and thus result in a characteristic group of symptoms and signs, including depression and winging of the scapula, drooped shoulder, reduced shoulder abduction, and pain. The elements evaluated in this long-term follow-up study include range of shoulder motion, pain, patients’ satisfaction, delay of surgery, surgical procedure, occupational status, functional outcome, and other clinical findings. Methods: We reviewed the medical records of a consecutive 37 patients (11 men and 26 women) having surgery to correct spinal accessory nerve injury. Neurolysis was the procedure in 24 cases, direct nerve repair for 9 patients, and nerve grafting for 4. Time elapsed between the injury and the surgical operation ranged from 2 to 120 months. The patients were interviewed and clinically examined after an average of 10.2 years postoperatively. Results: The mean active range of movement of the shoulder improved at abduction 44° (43%) in neurolysis, 59° (71%) in direct nerve repair, and 30° (22%) in nerve-grafting patients. No or only slight atrophy of the trapezius muscle was observable in 75%, 44%, and 50%, and no or controllable pain was observable in 63%, 56%, and 50%. Restriction of shoulder abduction preceded deterioration of shoulder flexion. Patients’ overall dissatisfaction with the state of their upper extremity was associated with pain, lower strength in shoulder movements, and occupational problems. Conclusion: We recommend avoiding unnecessary delay in the exploration of the spinal accessory nerve, if a neural lesion is suspected.

Abstract
The spinal accessory nerve (SAN) is susceptible to iatrogenic injury in the posterior cervical triangle. Early diagnosis and management of suspected SAN transection injuries are crucial in the restoration of shoulder stability and function. Although neurologic examination and electrodiagnostic testing can assess SAN function, they cannot assess nerve continuity. We report the use of sonography to prospectively evaluate the SAN in 6 patients with suspected iatrogenic SAN injury. Sonography directly visualized SAN transection in 4 cases, whereas sonographic findings were reported as "probable" transection in the fifth case and was nondiagnostic in the sixth case in the setting of extensive scarring.

Abstract
OBJECT
Iatrogenic injuries to the spinal accessory nerve (SAN) are not uncommon during lymph node biopsy of the posterior cervical triangle (PCT). In this study, the authors review the operative techniques and surgical outcomes of 156 surgical repairs of the SAN following iatrogenic injury during lymph node biopsy procedures.
METHODS
This retrospective study examines the authors’ clinical and surgical experience with 156 patients with SAN injury between 1980 and 2012. All patients suffered iatrogenic SAN injuries during lymph node biopsy, with the vast majority (154/156, 98.7%) occurring in Zone I of the PCT. Surgery was performed on the basis of anatomical and electro-physiological findings at the time of the operation. The mean follow-up period was 24 months (range 8–44 months).
RESULTS
Of the 123 patients who underwent graft or suture repair, 107 patients (87%) improved to Grade 3 functionality or higher using the Louisiana State University Health Science Center (LSUHSC) grading system. Neurolysis was performed in 29 patients (19%) when the nerve was found in continuity with recordable nerve action potential (NAP) across the lesion. More than 95% of patients treated by neurolysis with positive NAP recordings recovered to LSUHSC Grade 3 or higher. Forty-one patients (26%) underwent end-to-end repair, while 82 patients (53%) underwent graft repair, and Grade 3 or higher recovery was assessed for 90% and 85% of these patients, respectively. The average graft length used was 3.81 cm. Neurotization was performed in 4 patients, 2 of whom recovered to Grade 2 and 3, respectively.
CONCLUSIONS
SAN injuries present challenges for surgical exploration and repair because of the nerve’s size and location in the PCT. However, through proper and timely intervention, patients with diminished or absent function achieved favorable functional outcomes. Surgeons performing lymph node biopsy procedures in Zone I of the PCT should be aware of the potential risk of injury to the SAN.

Abstract
Spinal accessory nerve palsy may lead to dysfunction or paralysis of the trapezius muscle. Common causes are iatrogenic or secondary due to trauma, infection or tumour. Idiopathic palsy is considered extremely rare. We present the case of a 42-year-old Caucasian male suffering from a unilateral, isolated paralysis of his ipsilateral trapezius muscle. There was no related trauma, nor any past history of surgical procedures. An electromyographic study confirmed the idiopathic paralysis of the distal segment of the spinal accessory nerve.

Abstract
Internal jugular vein catheterization has been implicated in spinal accessory nerve (SAN) injuries after coronary artery bypass grafting (CABG). Stretch injury due to prolonged positioning during CABG has also been proposed as another mechanism of injury. Herein we describe a male patient with left shoulder pain and abduction difficulty following CABG, who displayed electromyographic abnormalities confined to the left upper trapezius muscle. Internal jugular vein catheterization had not been performed during surgery. Although unusual, the possibility of upper trapezius muscular branch paralysis should be considered in patients with shoulder pain or weakness after CABG.

Abstract
We describe two patients with uncommon causes of iatrogenic injuries and review the anatomy, presentation, possibilities of repair, and results. The incidence of such nerve injuries during lymph node biopsies is 3%-10%, but the diagnosis is often delayed. Symptoms are shoulder pain and inability to abduct the arm beyond the horizontal plane. Surgical repair may improve function and pain and should be performed early, preferably within six months, but prevention of nerve injury is most important.

Abstract
Lesions of the spinal accessory nerve are usually iatrogenic, especially after lymph node extirpation on the neck. Between 1994 and 2003, 31 patients were operated on in the Neurosurgical Department of the University of Ulm for iatrogenic lesions of the XIth cranial nerve. Of 31 patients, 22 had undergone a previous lymph node extirpation, 2 had been injured during a selective peripheral denervation for spasmodic torticollis, and the other 7 patients by different causes. The neurosurgical intervention was performed 0-19 months after trauma (mean 7.2 months). All patients showed paresis/atrophy of the trapezius muscle, and the abduction of the shoulder was markedly reduced. Additional neck and/or shoulder pain was present in 29 of 31 cases. In seven cases, the nerve was compressed by scar tissue and subsequently treated by external neurolysis. Ten patients underwent an end-to-end anastomosis; autologous sural nerve grafting was necessary in 13 cases. After a mean follow-up of 12.6 months, 7 of 31 patients completely recovered. Of 31 patients, 19 experienced partial relief of pain and weakness. Only five patients remained unchanged. The clinical findings after autologous nerve grafting, end-to-end reconstruction, or external neurolysis did not show any significant differences. Microsurgical reconstruction of iatrogenic injury of the spinal accessory nerve is very promising if the interval between trauma and surgical revision is less than 6 months. Up to 12 months, partial recovery can be achieved. Outcome after longer delay is unsatisfactory.

Abstract
BACKGROUND Spinal accessory nerve palsy causing trapezius dysfunction can lead to significant disability. Diagnosis is frequently delayed or inaccurate leading to inappropriate treatment. METHODS We describe new clinical signs for trapezius muscle dysfunction and palsy, and accessory nerve palsy, viz. The Active Elevation Lag sign and the Triangle sign. These signs help to differentiate between scapular winging due to trapezius dysfunction and that due to serratus anterior dysfunction. The signs are based on the principle that the deficiency of trapezius function causes an ;active forward elevation lag' with compensatory spinal hyperextension, and lead to the Triangle sign in the prone position, whereas no such lag is found in patients with pure serratus anterior dysfunction. Video recordings of clinical examination of 10 patients, 5 with isolated spinal accessory nerve palsy and 5 with long thoracic nerve palsy (confirmed by neurophysiology studies) were blinded and reviewed by 8 assessors. RESULTS Of the total of 80 readings, 100% sensitivity and 95% specificity were found, in correlation with the diagnosis confirmed by neurophysiology studies, with positive predictive value of 95% and negative predictive value of 100%. CONCLUSION These are simple clinical signs, easy to perform which are useful in diagnosing trapezius weakness in clinical practice.

Abstract
PURPOSE This study evaluated patient-reported outcome and the factors associated with disability after an upper extremity nerve injury. We hypothesized that patients at least 6 months after injury would report considerable disability and that pain would be the strongest predictor of the Disabilities of the Arm, Shoulder, and Hand (DASH) score. METHODS After research ethics board approval, the medical charts of patients with these inclusion criteria were reviewed: adults; presenting to a nerve surgeon; 6 months or greater after nerve injury. Patients completed the DASH questionnaire and the Short Form-36 (SF-36) as a routine part of the initial evaluation. These data were reviewed retrospectively to determine predictors of the DASH score. RESULTS There were 84 patients (mean age, 39 years; SD, 14 years) with brachial plexus (n=27) and peripheral nerve (n=57) injuries. The mean time after injury was 38 months (SD, 47). For all SF-36 domains, the mean values of the nerve-injured patients were significantly lower than the normative data, indicating a lower health status. The mean DASH score was 52 (SD, 22) of 100. Significantly more disability was associated with more SF-36 bodily pain and with brachial plexus injuries. In the final regression model, SF-36 bodily pain, age, and nerve injured were significant predictors of the DASH score. SF-36 bodily pain accounted for 35% of the variance. CONCLUSIONS Substantial long-term disability (high DASH scores) was found in patients after nerve injury that was predicted by higher pain, older age, and brachial plexus injury. Further investigation of this pain and the associated factors may provide the opportunity for improved health-related quality of life. TYPE OF STUDY/LEVEL OF EVIDENCE Prognostic II.

Abstract
Iatrogenic injury to the spinal accessory nerve is one of the most common causes of trapezius muscle palsy. Dysfunction of this muscle can be a painful and disabling condition because scapular winging may impose traction on the soft tissues of the shoulder region, including the suprascapular nerve. There are few reports regarding therapeutic options for an intracranial injury of the accessory nerve. However, the surgical release of the suprascapular nerve at the level of the scapular notch is a promising alternative approach for treatment of shoulder pain in these cases. The author reports on 3 patients presenting with signs and symptoms of unilateral accessory nerve injury following resection of posterior fossa tumors. A posterior approach was used to release the suprascapular nerve at the level of the scapular notch, transecting the superior transverse scapular ligament. All patients experienced relief of their shoulder and scapular pain following the decompressive surgery. In 1 patient the primary dorsal branch of the C-2 nerve root was transferred to the extracranial segment of the accessory nerve, and in the other 2 patients a tendon transfer (the Eden–Lange procedure) was used. Results from this report show that surgical release of the suprascapular nerve is an effective treatment for shoulder and periscapular pain in patients who have sustained an unrepairable injury to the accessory nerve.

Abstract
STUDY DESIGN Retrospective case series. BACKGROUND Spinal accessory nerve palsy (SANP) is common following neck dissection surgery and can occur with blunt or penetrating trauma to the lateral neck region and cervical stretch injuries. Early detection of SANP remains a clinical challenge and the condition is often misdiagnosed. The purpose of this case series is to describe the associated history, signs, and symptoms related to SANP and increase awareness of the scapular flip sign as a clinical sign associated with SANP. CASE SERIES DESCRIPTION: Twenty subjects (13 male, 7 female) presented with pain and decreased shoulder function following head and neck surgery or posttrauma. All patients were thoroughly examined and the scapular flip sign was assessed. All patients presented with a cluster of signs and symptoms including trapezius atrophy, shoulder girdle depression, limited active shoulder abduction to less than 90 degrees , shoulder pain, and shoulder weakness. A positive scapular flip sign was present in all cases. The middle and lower trapezius were rated as 0/5, based on manual muscle testing, indicating no identifiable muscle activation against resistance. DISCUSSION A typical history and consistent signs and symptoms were found related to SANP. A strong relationship appeared between the presence of the scapular flip sign and SANP. The suspected mechanism for the scapular flip sign is the unopposed pull of the humeral external rotators by the inactive middle and lower trapezius. Early identification of SANP can assist with the prognosis, explain persistent impairments and functional deficits, motivate appropriate diagnostic testing and interventions, and help maximize outcome. Further research to validate the scapular flip sign and establish a clinical prediction rule for the diagnosis of SANP should be performed.

Abstract
We report on the surgical results of spinal accessory nerve injuries between 1992-2003. We operated on 10 patients (9 female, and 1 male) who had injuries of the spinal accessory nerve. All injuries were iatrogenic. The mean age of patients was 39.2 years (range, 20-57 years). The average interval between date of injury and surgery was 7 months (range, 4-12 months). All patients had stiffness and pain in the shoulder girdle. The average active abduction of the shoulder joint was 79.5 degrees (range, 60-100 degrees ) before surgery. End-to-end repairs were performed in 7 cases, and graft repairs were indicated in 3 cases. The mean follow-up period was 18.4 months (range, 8-36 months). The average active abduction of the shoulder joint was 171 degrees (range, 140-180 degrees ) at time of final follow-up.

Abstract
Trapezius muscle palsy after accessory nerve injury leads to periscapular pain and shoulder motion deficit. The results of accessory nerve repair generally are good, but surgery is difficult. The difficulty consists of finding the nerve stumps that are embedded in fat and scar tissue from previous surgeries or injuries. Five patients with accessory nerve lesions had surgery and grafting of the accessory nerve. We dissected the proximal stump of the accessory nerve within the fibers of the sternocleidomastoid muscle and in the vicinity of the greater auricular nerve. To achieve dissection of the distal nerve stump, the deep cervical fascia was detached from the trapezius muscle 3 cm cephalad to the clavicle. The detached fascia and the trapezius muscle were flipped similar to book pages. The motor branches entering the trapezius muscle were visualized and followed toward the accessory nerve. A sural nerve graft with a mean length of 6.6 cm was used for grafting. Uncomplicated identification of the nerve stumps was possible in all patients. After accessory nerve grafting, pain and motion consistently improved in all patients. The technique proposed here ensures reliable and rapid identification of the divided stumps of the accessory nerve.

Abstract
BACKGROUND Injury to the spinal accessory nerve causes paralysis of the trapezius muscle, which is a painful and disabling condition. Many injuries are iatrogenic. Diagnosis is often made after a long delay, suggesting that current clinical signs are inadequate. METHODS Accessory nerve palsy is known to be a cause of winging of the scapula. Observation of six patients with accessory nerve palsy has shown that winging of the scapula is most prominent when the patient actively externally rotates the shoulder against resistance. RESULTS This is in contrast to the other causes of winging of the scapula including long thoracic nerve palsy and muscular dystrophy, where the scapula is most prominent on flexion or abduction of the shoulder. CONCLUSION We propose that the resisted active external rotation test should be regarded as the key clinical sign for accessory nerve palsy.

Abstract
BACKGROUND Injury to the spinal accessory nerve in the posterior cervical triangle leads to paralysis of the trapezius muscle. The aim of this study was to determine the indications for nerve repair or reconstructive surgery according to the etiology, the duration of the preoperative delay, and specific patient characteristics. METHODS Of twenty-seven patients with a trapezius palsy, twenty were treated with neurolysis or surgical repair (direct or with a graft) of the spinal accessory nerve and seven were treated with the Eden-Lange muscle transfer procedure. Lymph node biopsy was the main cause of the nerve injury. The nerve repairs were performed at an average of seven months after the injury, and the reconstructive procedures were done at an average of twenty-eight months. Nerve repair was performed for iatrogenic injuries of the spinal accessory nerve, within twenty months after the onset of symptoms, and in one patient with spontaneous palsy. Reconstructive surgery was performed for cases of trapezius palsy secondary to radical neck dissection, for spontaneous palsies, and after failure of nerve repair or neurolysis. The mean follow-up period was thirty-five months. The functional outcome was assessed clinically on the basis of active shoulder abduction, pain, strength of the trapezius on manual muscle-testing, and level of subjective patient satisfaction. RESULTS The results were good or excellent in sixteen of the twenty patients treated with nerve repair and in four of the seven patients treated with the Eden-Lange procedure. Poor results were seen in older patients and in patients with a previous radical neck dissection. CONCLUSIONS Good results can be expected from a repair of the spinal accessory nerve if it is performed within twenty months after the injury, as the nerve is basically a purely motor nerve and the distance from the injury to the motor end plates is short. Muscle transfer should be performed in patients with spontaneous trapezius palsy, when previous nerve surgery has failed, or when the time from the injury to treatment is over twenty months. Treatment is less likely to succeed when the patient is older than fifty years of age or the palsy was due to a radical neck dissection, penetrating injury, or spontaneous palsy.

Abstract
OBJECTIVE AND HYPOTHESIS This study presents a case report of a patient who sustained an iatrogenic proximal accessory nerve injury that was treated with a medial pectoral to accessory nerve transfer. STUDY DESIGN Case study. MATERIALS AND METHODS Chart of one patient who was treated with a medial pectoral to accessory nerve transfer was reviewed. RESULTS Five months after excision of a branchial cyst that resulted in a very proximal injury to the accessory nerve, this patient underwent a medial pectoral to accessory nerve transfer. At final follow-up, 3 years after surgery, the patient had full abduction overhead with some residual shoulder/scapular discomfort and mild scapular winging. CONCLUSION The medial pectoral to accessory nerve transfer provides a viable surgical option with good reinnervation of the trapezius muscle in patients with a proximal accessory nerve injury where standard nerve repair or graft techniques are not feasible.

Abstract
OBJECTIVE Iatrogenic injury to the spinal accessory nerve is not uncommon during neck surgery involving the posterior cervical triangle, because its superficial course here makes it susceptible. We review injury mechanisms, operative techniques, and surgical outcomes of 111 surgical repairs of the spinal accessory nerve. METHODS This retrospective study examines clinical and surgical experience with spinal accessory nerve injuries at the Louisiana State University Health Sciences Center during a period of 23 years (1978-2000). Surgery was performed on the basis of anatomic and electrophysiological findings at the time of operation. Patients were followed up for an average of 25.6 months. RESULTS The most frequent injury mechanism was iatrogenic (103 patients, 93%), and 82 (80%) of these injuries involved lymph node biopsies. Eight injuries were caused by stretch (five patients) and laceration (three patients). The most common procedures were graft repairs in 58 patients. End-to-end repair was used in 26 patients and neurolysis in 19 patients if the nerve was found in continuity with intraoperative electrical evidence of regeneration. Five neurotizations, two burials into muscle, and one removal of ligature material were also performed. More than 95% of patients treated by neurolysis supported by positive nerve action potential recordings improved to Grade 4 or higher. Of 84 patients with lesions repaired by graft or suture, 65 patients (77%) recovered to Grade 3 or higher. The average graft length was 1.5 inches. CONCLUSION Surgical exploration and repair of spinal accessory nerve injuries is difficult. With perseverance, however, these patients with complete or severe deficits achieved favorable functional outcomes through operative exploration and repair.

Abstract
OBJECTIVE This study assessed patient outcome following surgical reconstruction of the accessory nerve after an iatrogenic injury. STUDY DESIGN A retrospective chart review of 8 patients was performed. RESULTS There were 3 men and 5 women in the study, and the mean time between injury and nerve graft/repair surgery was 5 months. Four injuries were sustained during a lymph node biopsy. Electromyography revealed a complete accessory nerve injury in all cases. In 6 cases, a nerve graft was required (mean length, 3.6 cm), and in 2 cases, a direct nerve repair was possible. The trapezius muscle was successfully reinnervated in all cases. In total, full shoulder abduction was achieved in 6 cases; in the remaining 2 cases, the patients achieved shoulder abduction to 90 degrees. CONCLUSION Functional deficit after accessory nerve injury is significant. Nerve graft/repair reconstruction reliably yields a satisfactory result, providing good scapular rotation and thus good shoulder function.

Abstract
OBJECTIVE To determine feasibility of ultrasonography in detecting the normal accessory nerve as well as pathologic changes in cases of accessory nerve palsy. METHODS Four patients with accessory nerve palsy were investigated by ultrasonography. Three cases of accessory nerve palsy after lymph node biopsy and neck dissection were primarily diagnosed on the basis of ultrasonography using a 5- to 12-MHz linear transducer. In addition, we performed ultrasonography in 3 cadaveric specimens to show the feasibility of detecting the accessory nerve. RESULT Nerve transection (n = 2), scar tissue (n = 1), and atrophy of the trapezius muscle (n = 4) were confirmed by electroneurographic testing and surgical nerve inspection. In 1 case in which a patient had a whiplash injury with accessory nerve palsy, ultrasonography showed atrophy of the trapezius muscle with a normal nerve appearance. CONCLUSIONS Ultrasonography allows visualization of the normal accessory nerve as well as changes after accessory nerve palsy.

Abstract
The term spinal accessory nerve plexus may be defined as the spinal accessory nerve with all its intra- and extracranial connections to other nerves, principally cranial, cervical, and sympathetic. The term is not new. This review examines its applied anatomy in head and neck cancer and atherosclerosis. Over the centuries, general studies of neural and vascular anatomy and embryology formed a basis for the understanding upon which the plexus is described. During the past century, its anatomy and blood supply have come to be better understood. The importance of almost all of the plexus to head, neck, and upper extremity motor and sensory functions has come to be realized. Because of this understanding, surgical neck dissection has become progressively more conservative. This historical progression is traced. Even the most recent anatomic studies of the spinal accessory nerve plexus reveal configurations, new to many of us. They were probably known to classical anatomists, and not recorded in readily available literature, or not recorded at all. Human and comparative anatomic studies indicate that the composition of this plexus and its blood supply vary widely, even though within the same species their overall function is very nearly the same. Loss of any of these structures, then, may have very different consequences in different individuals. As a corollary to this statement, data are presented that the spinal accessory nerve itself need not be cut during surgical neck dissections for severe impairment to occur. In addition, data are presented supporting the theory that atherosclerosis by obstructing vessels to this plexus and its closely connected brachial plexus will very likely result in their ischemic dysfunction, often painful. Finally evidence, as well as theory, is stated concerning anatomic issues, methodology, outcome, and possible improvements in surgical procedures emphasizing conservatism.

Abstract
Nerve entrapment syndromes can occur in athletes. The repetitive and vigorous use or overuse of the upper extremity makes the athlete particularly vulnerable to disorders of peripheral nerves. Understanding the clinical signs and symptoms is essential to treatment. The pertinent anatomy, clinical presentation, treatment, and rehabilitation necessary for return to sports for various nerve entrapments have been described. This should enable the physician caring for the athlete to help prevent injury and to guide appropriate treatment, if intervention becomes necessary.
