Superior articular facet (a)Supraspinous ligament (b) interspinousligament (c) facet joint capsule (d) posterior longitudinal ligament • • • • • • • SCM Scalen muscle PV Longus capitis Longus colli Rectus capitis ant Splenius capitis • • • • • Each disk consists of an outer anulus fibrosus and an inner nucleus pulposus and a cephalad and caudad end plate. The anulus fibrosus is innervated by the sinuvertebral nerve, formed by branches of the ventral nerve root and the sympathetic plexus. The pressure within the disk is highest with flexion, which may explain why individuals with a disk herniation find this position most uncomfortable. Disk degeneration with aging includes loss of water content with resultant loss of height, annular tears, and myxomatous changes, increasing the risk of disk herniation. Herniation typically occurs in the posterolateral aspect of the disk, where the posterior longitudinal ligament is not present and the anulus fibrosus is at its weakest. • Spinal cord : posterior column, the lateral columns, and the anterior column. • The posterior column: proprioceptive, vibratory, and tactile sensation. • The lateral column – lateral corticospinal tract: motor fibers, – and the spinothalamic tract: pain and temperature sensation from the contralateral side of the body. • The anterior column: touch sensation. – Eight total cervical nerve roots on each side as the dorsal and ventral roots converge to form the spinal nerve within the vertebral foramen. • The cervical spine is the most mobile segment of the spine with approximately a 90-degree arc of motion in flexion and extension, with three fourths of this due to extension. • The maximal range of motion in the sagittal plane within the subaxial spine is at the C5-C6 level, making it a common site of disk degeneration. • Rotation encompasses approximately 80 to 90 degrees of motion with 50% of this occurring at the atlantoaxial joint. Functıonal Anatomy • • • • • The most mobile segment of the spine 7 cervical vertebrae 14 apophyseal (faset) joints 12 joints of Luschka Ligaments (posterior longitudinal, anterior longitudinal, flaval, interspinous) • Muscles Faset joints are posterior intervertebral joints. They are true sinovial joints and enable the head movement. Luschka joints are between semilunar joint surface of upper vertebra and uncus of lower vertebra. They protect spinal colon aganist disc protrusion • • • • Flexion: 60-90 Extension Rotation: 90 Lateral flexion: 45 – Atlantoaxial joint: 45 degree rotation – Atlanto-occipital joint: 10 d flexion, 25 d extension – C5-C6 , C4-C5 maximal range of movement Pain sensitive structures • • • • • • Ligaments Nerve roots Articular facets and capsules Muscles Dura External fibers of anulus fibrosus Disorders cause neck and upper extremity pain Cervical vertebra colon: cervical spondylosis (OA) cervical disc herniation spinal stenosis instability Wiplash injury Cervical cord diseases (Tumor, syringomyeli) Rheumatologic disorders: Ankylosing spondylitis, Rhematoid arthritis, Polymyalgia Rheumatica, Fibromyalgia, Myofascial pain syndrome Infectious: Osteomyelitis, dissit, epidural/intradural/subdural abces, retropharengeal abces Endocrin: osteoporosis, osteomalasia, paget disease Trauma: hard muscle contraction, sport injury, work conditions, postur Thoracic outlet syndrome Shoulder, elbow, wrist Neuropathies Artheritis (vertebral and cranial, Takayasu) Referred pain Structures That Cause Neck Pain • • • • • • • Akromioclavicular joint Heart and coronary disease Apex of lung, Pancoast’s tumour Diaphragm muscle (C3-C5 inn) Gallbladder Spinal cord tumour Temporomandibular joint Axial Neck Pain • Axial neck pain describes a pattern of pain that is localized to the occiput and neck region. • Degenerative arthritis within the upper cervical spine can manifest as suboccipital headache and localized pain. This is termed cervicogenic headache and is thought to result from irritation of the greater occipital nerve. Cervical Strain and Sprain • Strain: – injury of contractile tissues by stretching (muscle, lig.) – Pain is localized on neck – Decreased lordosis, pv spasm – No neurologic sign • Sprain: – Tissue rupture and bleeding by stretching (capsule, lig., bursa, vessels, cartilage, dura) Cervical Spondylosis • Degeneration of IVD, facet and luschka • Age, microtrauma, ergonomy, genetic • Syndromes due to spondylosis – Radiculopathy – Vertebrobasilar insufficiency – Cervical myelopathy Radiculopathy • • • • • Radicular pain Paresthesias Superficialsensory deficits Variation of DTR Muscle strength loss • If these deficits are minor and tolerable, it is reasonable to treat with conservative care with close follow-up to ensure that the deficit is not progressive. Disabling deficits should be treated operatively because prolonged nerve compression can result in irreversible changes. • In patients without a neurologic deficit, it is reasonable to expect a good outcome with conservative care. Instability • Deterioration of cervical colon stability by physical loads • X-ray Myelopathy • Myelopathy is the clinical presentation of long tract signs resulting from compression of the spinal cord. • Myelopathy: – a tumor or infection – instability owing to systemic arthritides or connective tissue disorders, – degenerative changes within the cervical spine. • Factors that contribute to the development of myelopathy : – congenitally narrow spinal canal, dynamic cord compression, dynamic thickening of the spinal cord, and vascular changes. • Cervical colon stenosis: osteophyte, disc herniation, lig. flavum and facet joint hipertrophy, posterior longitudinal lig. thickness, Paget, gout • The anteroposterior diameter in the subaxial spine for a normal adult measures 17 to 18 mm, and the cord measures 10 mm. Diameters of less than 13 mm are considered to be congenitally stenotic. • complaints of hand clumsiness or difficulty with balance. • worsening handwriting or difficulty buttoning buttons. • nausea and emesis caused by equilibrium dysfunction. • Paresthesias and dysesthesias may be present, often involving bilateral upper extremities and not following a dermatomal distribution. • wasting of hand intrinsics and bowel and bladder dysfunction. • Definitive indications for surgery: – presence of myelopathy for 6 months or longer, – progression of signs or symptoms, – difficulty walking, or change in bowel or bladder function. VBI • Blood supply of inner ear, vestibular and cochlear nucleii of medulla oblangata • Vertigo, headache, nausea • Coordination, memory deficit • Tinnitus, hearing loss, diplopia • Nistagmus, disphagia • Common property of those symptoms is that they are related with neck movement and local/radicular symptoms Cervical Disc Herniation • With age, the nucleus pulposus becomes vulnerable • With degenerative changes, – the disc space narrows, spinal column shortens – The intervertebral foramina become narrowed, movements become restricted, unusual mechanical strains on the sinovial joints result – The formation of osteophytes leads to encroachment on the spinal canal and intervertebral foramina – Changes in the caliber of the vertebral arteries can result because of the degenerative changes • Facet joints (sinovial) can be affected by various arthritic diseases • Uncovertebral joints have no sinovial membrane • Articular cartilage in all joints is avascular and aneural • All joints are supplied with sensory nerves and nutrient vessels on the segmental basis as well as with sympathetic pain fibers. • Pain from those joints are non-neuralgic and felt locally. • If the dura and its nerve are stretched, the accompanying nutrient vessels canbe narrowed and promptly cause ischemic neuralgic pain. • The main load-bearing structure of the neck is the intervertebral disk. • The IVD consists of fibroelastic envelope that has a blood supply and a nerve supply that is highly sensitive to stretching. • Nuc. Pulposus has has no nerve supply---painless • As the disk loses height, it places increased pressure on the joints • Surface areas are inadequate for the imposed pressure, they become irritaed • Irritation—inflammatory disease-----repair----formation of osteophytes Clinical Evaluation • • • • Patient’s history Physical examination Neuroimagining studies Neurophysiologic procedures • • • • • Sensory symptoms Weakness Articular symptoms Vascular symptoms Headache and occipital neuralgia – Nerve root sympathetic nerve compression, vertebral artery pressure, posterior occipital muscle spasm • Pseudoangina pectoris • (C6-C7) Clinical Examination • Inspection: lordosis, scoliosis, torticollis, active limtaiton, skin lesions • Palpation • Range of servical spine motion • Motor signs • Reflexes • Sensory signs Nerve Root Symptom Correlate C3 Suboccipital pain with extension to back of ear C4 Pain from caudad aspect of neck to superior aspect of shoulder C5 Numbness over shoulder and down lateral aspect of arm to midportion.

Weakness in wrist extension, elbow flexion, and supination. Diminished brachioradialis and biceps reflex Sensory component can mimic carpal tunnel syndrome C7 Numbness and pain down posterior aspect of arm and forearm to long finger. Weakness in triceps, wrist flexion, and finger extensors Most frequent. Entrapment of posterior interosseous nerve can mimic motor component, but no sensory deficits are present C8 Numbness into ulnar two digits. Weakness in FDP to IF and LF and FPL T1 Numbness into ulnar aspect of forearm and weakness in hand intrinsics Anterior interosseous nerve entrapment can mimic a radiculopathy of C8 or T1, but sensory changes and involvement of thenar muscles are not present. Ulnar nerve entrapment spares short thenar muscles with exception of adductor pollicis.

Treatment Conservative treatment • Postural exercises • Shoulder girdle strengthening exercises and scalene muscles streching exercises • Myorelaxan • NSAİİ • Superficial and deep heat, iontophoresis,TENS Surgery • Avoid prolonged positions with their arms held out or overhead. • Avoid sleeping with the arm extended up behind the head. • Have rest periods at work to minimize fatigue. • Weight reduction • Avoid sleeping on their stomach with their arms above the head. • Not repetitively lift heavy objects. Shoulder Pain Anatomy And Function • The shoulder joint is the most mobile joint of the body • Joint stability: labrum, capsule and the glenohumeral ligaments, the rotator cuff (dynamic stability) of the joint. The shoulder consists of three joints—acromioclavicular (AC), sternoclavicular, and glenohumeral—and two gliding planes— the scapulothoracic and subacromial surfaces • Knowledge of the route of the tendon of the long head of the biceps through the bicipital groove and onto the superior aspect of the glenoid helps in understanding bicipital tendinitis Shoulder Pain Causes • Intransic causes: – – – – – – – – – – Impingement Calcific tendinits Frosen shoulder Biceps tendinitis Glenohumeral instability Degeneration Arthritis Avascular necrosis Fracture tumor • Extransic causes: – Cervical radiculopathy – Bracial neurit, bracial plexus injury – Toracic outlet syndrome – Cardiac referred pain – Abdomial referred pain – Tumor – Fracture – Fibromiyalgia – Myofacial pain syndrome Radiographic Assessment • Anteroposterior views with a 30-degree caudal tilt (Rockwood view), • Outlet view (scapular Y with 10- to 15-degree caudal tilt), • Axillary view. • Internal and external rotational views • Scapular Y view, and an axillary view: traumatic injury • Posterior or anterior subluxation of the humeral head : axillary view • • • • Computed tomography Ultrasonography Magnetic resonance imaging EMG Bicipital Tendinitis And Rupture • • • • • The biceps tendon aids in flexion of the forearm, supination of the pronated forearm if the elbow is flexed, and forward elevation of the shoulder. Anterior shoulder pain. Yergason's supination sign Treatment generally is conservative and consists of rest, analgesics, NSAIDs, and local injection of glucocorticoids. Patients with refractory bicipital tendinitis and recurrent symptoms of subluxation are treated by arthroscopic interventions. Impingement • • • • • Impingement : encroachment of the acromion, coracoacromial ligament, coracoid process, or AC joint on the rotator cuff as it passes beneath them during glenohumeral motion. The mechanical impingement : shape and slope of the acromion, proliferative spur formation of the acromion or degenerative changes of the AC joint. stage I lesion: – edema and hemorrhage conservative treatment Stage II lesions: – fibrosis and thickening of the tendon after repeated episodes of mechanical impingement over time. Treated conservatively, but attacks may recur. If symptoms persist despite adequate conservative management for more than 6 to 12 months, surgical intervention is warranted. Stage III lesions: – rotator cuff tears, biceps tendon rupture, and bone changes. Pain, weakness, or supraspinatus atrophy, Surgical treatment • Pain: located over the anterior and lateral aspects of the shoulder and may radiate into the lateral deltoid. • The pain may worsen with sleeping on the affected extremity and is exacerbated by overhead activity. • Tenderness on palpation: greater tuberosity bicipital groove, AC joint • The impingement sign • Radiographs • Arthrography, MRI, and ultrasound Rotator Cuff Tear • Inflammatory diseases • Metabolic conditions such as renal osteodystrophy • Agents such as glucocorticoids • A traumatic episode, such as falling on an outstretched arm or lifting a heavy object • The usual presenting symptoms are pain and weakness of abduction and external rotation • Atrophy of the supraspinatus and infraspinatus muscles • Drop arm test • Conservative treatment – The mainstay of conservative therapy is exercise. – Rehabilitation stresses pain relief with exercises aimed at restoring shoulder motion and strengthening the remaining cuff muscles, deltoid, and scapular stabilizers • Steroid and local anesthetic injections • If the patient fails to improve after 3 months of conservative treatment, or does not continue to improve after three sequential injections, surgical options should be discussed Calcific Tendinitis • The cause: degeneration of the tendon, which leads to calcification through a dystrophic process • A common clinicopathologic correlation is three distinct phases of the disease process: – the precalcific or formative phase, which can be relatively painless – the calcific phase, which tends to be quiescent and may last months to years and the resorptive or – postcalcific phase, which tends to be painful, as calcium crystals are resorbed • Impingement-type pain • The symptoms may last a few weeks or a few months. During the latter phase, pain and decreased motion can lead to adhesive capsulitis • The acute inflammation can be treated with local glucocorticoid injection • NSAIDs, or both Adhesive Capsulitis • Adhesive capsulitis, or frozen shoulder syndrome (FSS), is a condition characterized by limitation of motion of the shoulder joint with pain at the extremes of motion – – – – Diabetes mellitus Parkinsonism Thyroid disorders Cardiovascular disease • Capsular contracture is thought to result from adhesion of the capsular surfaces or fibroblastic proliferation in response to cytokine production. • More common in women in their 40s and 50s. • Typically, the patient relays a history of diffuse, dull aching around the shoulder, with weakness and loss of motion occurring over a few months. • Stage one is the painful or freezing phase. • Phase two is the adhesive or stiffening phase and generally lasts 4 to 12 months. • The third phase is the resolution or thawing phase and may last 5 to 26 months. • In patients with a history of minimal or no trauma and FSS, a metabolic cause should be excluded. A complete blood cell count, erythrocyte sedimentation rate, serum chemistry, and thyroid function tests Glenohumeral Instability • Glenohumeral instability is a pathologic condition that manifests as pain associated with excessive translation of the humeral head on the glenoid during shoulder motion. • Anterior dislocation usually occurs with the arm in an abducted and externally rotated position, and the diagnosis is usually obvious. • Posterior dislocation is frequently associated with convulsive disorders or unusual trauma with the arm in a forward flexed and internally rotated position. • Plain radiographs are generally normal, although some inferior subluxation may be shown by obtaining stress radiographs with weights. • Activities that stress the shoulder and produce symptoms are avoided. • Strengthening exercises of the shoulder girdle Osteonecrosis • The most common cause of osteonecrosis of the shoulder is avascularity resulting from a fracture through the anatomic neck of the humerus. • Fracture, steroid therapy in conjunction with organ transplantation, systemic lupus erythematosus, or asthma. • Other conditions: hemoglobinopathies, pancreatitis, and hyperbarism. Milwaukee shoulder • Deposition of calcium pyrophosphate dihydrate crystals, direct trauma, chronic joint overuse, chronic renal failure, and denervation. • Hemiarthroplasty or a reverse total shoulder arthroplasty may be indicated.

Signs and Symptoms • Tingling or numbness in part of the hand. • Sharp pains that shoot from the wrist up the arm, especially at night. • Burning sensations in the fingers. • Morning stiffness or cramping of hands. • Thumb weakness. • Frequent dropping of objects. • Inability to make a fist. • Shiny, dry skin on the hand. Causes • Pressure on the median nerve caused by swollen, inflamed or scarred tissue. • The sources of pressure include: -Repetitive motion injury (associated with continuous and rapid use of the fingers). • Inflammation of the tendon sheaths (sometimes from arthritis). • Fracture of the forearm. • Sprain or dislocation of the wrist. Treatments • • • • A wrist splint Hot and cold compresses Physical Therapy Surgery Ulnar Nerve Entrapment—Cubital Tunnel Syndrome • Entrapment of the ulnar nerve as it passes through the cubital tunnel just posterior to the medial epicondyle of the elbow can manifest with symptoms localized to the ulnar border of the hand • Paresthesias or numbness or both in the small and ring fingers • Tinel's sign • Prolonged elbow flexion reproduces the symptoms • Electrodiagnostic studies • Conservative treatment : – Help the patient avoid having the elbow flexed for prolonged periods, particularly at night – Soft, or semirigid, elbow splints prevent elbow flexion beyond 50 to 70 degrees – Medial elbow pads – NSAIDs Flexor Carpi Radialis and Flexor Carpi Ulnaris Tendinitis • Similar to other tendinopathies around the wrist, irritation of the wrist flexors occurs with stress of the wrist in a particular position. • Activities that require forced wrist flexion for prolonged periods or with repetition put patients at risk for inflammation around the flexor carpi radialis tendon or the flexor carpi ulnaris tendon or both. • The condition manifests with tenderness along the course of the tendon, especially near its insertion. • Wrist flexion against resistance with radial or ulnar deviation reproduces the symptoms. • Treatment consists of splinting and rest, elimination of activities that cause pain, and oral NSAIDs. Injection of corticosteroid into the flexor carpi radialis or flexor carpi ulnaris sheath may be curative. Dupuytren’s Contracture • Flexion contracture of MP and PIP joints from shortening/adhesions in palmar aponeurosis – most common at 4th and 5th fingers • Positive table top test Trigger Finger Osteoarthritis of the Digits DeQuervain’s Syndrome • Tenosynovitis of extensor pollicis brevis and abductor pollicis longus tendons from repetitive stress (radial deviation) • Presents with pain/swelling to proximal thumb/distal radius, pain with radial/ulnar wrist deviation and thumb extension and abduction • Treated conservatively with rest (immobilization), NSAIDs, modalities Finkelstein’s Test • Evaluative for DeQuervain’s syndrome • Thumb flexed across palm and locked in by finger flexion – wrist placed in ulnar deviation – positive if pain reproduced or increased • Can present with falsepositive results
