<ul><li> 1. Evaluation of a Patient with Neck Pain </li></ul> <p> 2. Prevalence Approximately 10 percent of the adult population has neck pain at any one time Prevalence is similar to LBP Point prevalence 10-15% in the US Life time prevalence 67-71% 3. 2007 Task Force on Neck Pain Grade I: No signs of major pathology and little interference with daily activities Grade II: No signs of major pathology but may impact daily activities Grade III: Neck pain with neurological signs or symptoms (radiculopathy) Grade IV: Neck pain with major pathology: fracture, myelopathy, neoplasm, infections 4. Red Flags for Axial Neck Pain Advanced age History of malignancy Immunocompromised patient Fever, Chills Weight loss Fatigue History of recent significant fall or major trauma Night time awakening Severe non mechanical neck pain Neurological signs or symptoms ( gait difficulty, bowel or bladder dysfunction) 5. Anatomy of the Neck The cervical spine consists of seven vertebrae denoted as C1 C7 The bony anatomy of Atlas and axis are unique The atlas is a ring, no vertebral body The axis has a vertebral body with the dense/odontoid peg The odontoid form a true synovial joint with anterior arch of the atlas. C3-C7 vertebrae has fairly same anatomy Cervical spine 6. Anatomy of Cervical Spine 7. Anatomy of Cervical Spine 8. Anatomy of Cervical Spine (Contd ) The atlantooccipital joint allows 1/3rd of flexion extension 50% of the lateral bending and 50% of the rotation The articulation between C3-C7 vertebrae allow rest of the movement. Movements 9. Muscles of the neck 10. Muscles of the neck 11. Muscles of the neck originates on the sternum and clavicle inserts on the mastoid process of the temporal bone. When contracted on one side it turns the head sideways in the other direction. When both sides contract, it pulls the head forward and down The sternocleidomastoid muscle extends upward from upper thoracic to the temporal bone. Contraction on one side causes the head to rotate and extend to one side. Contraction together causes extension of the head at the neck. The Splenius capitus extends over the neck but is considered a superficial muscle of the back move the shoulder blade up and down bring the head and neck in a backward direction rotate and side bend the neck The trapezius extends upward from upper thoracic to the occipital bone. If one of the muscles acts alone the head is rotated to the side When the muscles contract together they extend the head at the neck ( along with the splenius capitus). The semipinalis capitus 12. Muscles of the neck 13. Nerves 14. Nerves 15. Cervical Strain Results from physical stresses of everyday life: poor posture sleeping habits Pathogenesis: Injury to paraspinal muscles &amp; ligaments spasm of cervical &amp; upper back muscles 16. Cervical Strain Symptoms: acute axial neck and trapezius pain Stiffness &amp; tightness in upper back &amp; shoulder No red flag No neurological dysfunction X-ray &amp; APR normal Lasts for up to six weeks Persistence beyond 6 wk some other cause 17. Cervical Discogenic Pain Commonest cause of neck pain Pathogenesis: Derangement of the disc architecture Symptoms: chronic axial neck pain Sometimes mild non-dermatomal shoulder and limb pain Exacerbated when the neck is held in one position for prolonged periods driving, reading, working at computer 18. Cervical Discogenic Pain Signs: tightness/spasm on palpation Axial neck discomfort with range of motion Decreased range of motion Normal neurological examination Diagnosis is usually radiological MRI indicates progressive disc degeneration Vertebral bodies are normal No root impingement 19. Cervical Facet Syndrome Symptom: chronic midline/slightly one-sided neck pain Sometimes non-dermatomally referred to shoulders, around scapula, occiput, proximal limb Predisposition: most important clinical clue Trauma with abrupt flexion-extension type injury Occupation involving repeated neck positioning in extension No red flag 20. Cervical Facet Syndrome Examination: no specific finding Tenderness over the region of one facet joint X-ray: non-specific Relieved by fluoroscopically guided anesthetic injection into a facet joint 21. Whiplash Injury: Pathogenesis Caused by an abrupt flexion/extension of the cervical spine Multiple structures injured soft tissues, spinal nerve, intervertebral disc, posterior longitudinal ligament, interspinous ligaments, alar ligaments, facet joints, or other osseous structures 22. Whiplash Injury: Features Severe pain, spasm, loss of range of motion in the neck and occipital headache Pain may be persistent Little identifiable abnormality seen on MRI, CT, X-ray, or bone scan imaging High resolution MRI: soft tissue damage at alar ligaments 23. Cervical Myofascial Pain Nonspecific manifestation of any pathology causing neck pain Regional pain with trigger points, taut bands, and pressure sensitivity Associations: muscle sensitivity, depression, insomnia, fibromyalgia 24. Thoracic Outlet Syndrome Neck and shoulder pain with referred pain to the upper extremities The triad of numbness, weakness, and a sensation of swelling of the upper limbs Variable neurovascular signs and symptoms Examination may demonstrate a positive Adson's test 25. Cervical Spondylotic Myelopathy Degenerative changes narrowing spinal canal resulting in cord injury/dysfunction Features: Weakness Incoordination Bowel or bladder retention or incontinence Sexual dysfunction UMN signs in lower limbs 26. Causes of Neck Pain. Soft tissue lesions o Acute neck strain o Posture-related neck pain o Whiplash injury o Myofascial pain Degenerative o Cervical spondylosis o Discogenic neck pain o Cervical disc prolapse o DISH 27. Causes of Neck Pain. Inflammatory arthropathies o RA, SPA Metabolic bone diseases o Paget's disease, osteoporosis Infections o Osteomyelitis o Tuberculosis: retropharyngeal abscess Malignancy Brachial plexus lesions Referred pain, fibromyalgia, torticollis 28. Causes of Neck Nain. Axial neck pain syndrome o Cervical strain o Discogenic pain o Cervical facet-mediated pain o Cervical "whiplash" syndrome o Myofascial pain 29. Causes of Neck Pain Predominantly cause extremity pain oCervical radiculopathy oCervical spondylotic myelopathy Non-spinal causes of neck pain o Thoracic outlet syndrome o Herpes zoster o Diabetic neuropathy o Infections o Malignancy o Referred pain 30. Evaluation Steps : - History - Clinical examination - Investigations 31. History Onset of pain Acute pain soft tissue lesions Chronic persistent pain- degenerative/metabolic Constant and increasing pain - mass effect Intermittent pain - instability or motion related pain Distribution of pain Well-localized pain - specific nerve root irritation Poorly localized pain-deep structures: muscles, bones, disc Duration Short duration generalized pain - benign pathology Longer duration - significant/ progressive pathology 32. History (Contd ) Character of pain Degenerative pain worsen as the day goes through Inflammatory pain worse in morning &amp; associated with stiffness Neuralgic pain: from irritation of dorsal sensory root Myalgic pain: from irritation of the ventral motor root Aggravating factors/Relieving factors Myofascial pain worsen with neck flexion Discogenic pain worsen with neck extension or rotation Presence of neuralgic symptoms Sensory loss and weakness-compression of dorsal root Bowel/ bladder involvement- myelopathy 33. History (Contd ) Important points: Pseudo-angina pectoris may arise from cervical spine Should be differentiated carefully difficult when true and pseudo-angina coexist Dyspnea, cardiac arrhythmia and drop attacks may have cervical spinal origin Eye, Ear &amp; throat symptoms may be due to cervical spine disease Neck pain may manifest concomitant with systemic disease 34. Clinical Examination Clinical examination includes Look - observe gait, head and neck posture Feel - palpation of soft tissue surrounding neck Move - see the range of motion Other neurological examination 35. Clinical Examination (Contd ) Patient should be observed in sitting or standing position Should be looked from front, side &amp; behind Anterior examination will establish whether neck is held straight or not (?torticollis) Lateral observation will establish whether normal curvature is maintained or not Posterior observation for C7 &amp; T1 spinous process A short rigid neck may be associated with developmental anomaly LOOK 36. Clinical Examination (Contd ) Muscle palpation- Local muscle tenderness can result from trauma Trapezius muscle tenderness is a non specific finding seen in- Cervical muscle strain Fibromyalgia, whiplash, cervical radiculopathy Severe muscular rigidity and guarding are associated with severe neck strain, occult vertebral body fracture, or dislocation FEEL 37. Clinical Examination (Contd ) Sternocleidomastoid muscle may be tender in whiplash injury Others to be palpated Lymph node Submandibular glands Parotid glands The thyroid Carotid pulses FEEL 38. Clinical Examination (Contd ) Normal movements of the cervical spine Can bend 45 degrees laterally Can rotate an average of 90 degrees Less rotation is abnormal Can forward flex to 60 degrees Can extend backward 75 degrees MOVE 39. Clinical Examination (Contd ) Types of movement If patient is able to comply safely with range of motion exercise then we should do Active ROM Passive ROM Motion against resistance 40. Clinical Examination (Contd ) Full extension- Tip of the nose and forehead should form a horizontal plane. Anterior flexion- The chin should allow touching the chest wall. Rotation- The chin should turn almost to the shoulder in the coronal plane Lateral flexion- Move the shoulder up to the ear with gentle restrain to the shoulder so that the neck flex laterally 41. Conditions Associated with Abnormal ROM. Cervical strain Cervical discogenic pain Cervical facet syndrome DISH Cervical radiculopathy Cervical myeloradiculopathy 42. Conditions Associated with Abnormal ROM Lateral is the earliest and most impaired movement in degenerative disease Rotation is first impaired in rheumatoid arthritis due to involvement of odontoid peg Movement is reduced in presence of muscular spasm or pain A uniformly stiff neck may be due to DISH, AS and recent trauma 43. Neurological Examinations Pain in a dermatomal distribution Compression of dorsal root Presence of neurological deficit (Sensory loss and weakness) - Minor or tolerable - Disabling Long tract sign Myelopathy 44. Location of Pain Source Upper posterolateral cervical region C0-1, C1-2, C2-3 Occipital region C2-3, C3 Upper posterior cervical region C2-3, C3-4, C3 Middle posterior cervical region C3-4, C4-5, C4 Lower posterior cervical region C4-5, C5-6, C4, C5 Suprascapular region C4-5, C5-6, C4 Superior angle of scapula C6-7, C6, C7 Midscapular region C7-T1, C7 Localization of Pain Generators 45. Provocative tests for radiculopathy: o Spurling maneuver head extension ipsilateral rotation ipsilateral tilting application of pressure on head top o The axial compression and traction test Provocative tests for myelopathy: o Hoffmann's test o Lhermittes test Picture: Spurling maneuver Provocative Tests 46. Adson's test: The arm is gradually elevated in an abduction arc The examiner fingers are held on the patient's radial pulse. The patient is asked to turn his head away from the tested side and take a deep breath If the pulse disappears as the arm is abducted beyond 90 degree, test is positive Provocative Tests 47. X-ray cervical spine Indications- Neck pain with history of trauma Neck pain after age of 50 Constitutional symptoms Neck pain not improved after conservative treatment Investigations 48. Common views- Lateral view to see vertebral curvature to see degree of osteoarthritis disc space narrowing bony fracture (Compressed) X-ray Cervical Spine 49. Oblique view to determine foramen encroachment by osteophytes X-ray Cervical Spine 50. PA View - to see lateral deviation of the cervical spine in severe torticollis Odontoid view - most appropriate in patients with acute trauma X-ray Cervical Spine 51. MRI of cervical spine: Indications: Red flags Objective neurologic impairment with weakness/reflex loss Evidence of cervical myelopathy Persistent moderate-to-severe symptoms despite conservative care Patients with dramatic bony tenderness combined with guarding Investigations (Contd ) 52. MRI can detects Disc herniations Foraminal stenosis Central canal stenosis Tumor Spinal cord changes from myelopathy, fractures and infection Investigations (Contd ) 53. When MRI Should Not be Done? A low value on a pain rating scale less than 3/10 Does not limit or interrupt daily activities such as driving, desk work, or sleep Does not affect occupation Easily ignored when distracted Other reassuring features: waxing and waning severity over years reasonable response to mild analgesics and heat gelling phenomenon (stiffness after prolonged single position) increase in symptoms with weather changes 54. Neurophysiologic investigations: EMG, NCV, somatosensory evoked potential Indications: Clinical examination and imaging studies fail to correlate Conflicting information To differentiate intrinsic joint pathology from a radiculopathy. To differentiate cervical spine disorders from peripheral nerve entrapment syndromes Investigations (Contd ) 55. Diagnostic Approach 56. Neck pain is a common condition with enormous medical and legal costs Physicians need to differentiate causes of neck pain Knowledge of the anatomy helps diagnosis and the differentiation of symptoms The history and clinical examination help to focus the differential diagnosis and to identify the origin of pain Cervical discogenic pain is the most common cause of neck pain Cervical radiculopathy is most commonly due to degenerative changes CT/MRI should be done with specific indication Patient usually improves with conservative treatment if there is no significant disease Take Home Message 57.
