29 • • • • Regional Conditions of the Neck Torticollis (Wryneck) Thoracic outlet syndrome Cervical rib Cervical disk syndromes Regional orthopedics deals with a vast array of interesting orthopedic problems Each region has its own peculiar problems depending on various factors like anatomical, physiological, occupational and others operating in that region An effort is made in this section to highlight the various regional orthopedic problems However, a detailed description of the regional disorders is avoided as it is outside the scope of this book The student is requested to refer bigger books in orthopedics in case he or she desires a detailed study of the regional problems TORTICOLLIS (WRYNECK) Torticollis is defined as the rotational deformity of cervical spine that causes turning and tilting deformity of the head and neck (Fig 29.1) • Unilateral muscle paralysis, e.g polio • Neuritis of spinal accessory nerve • Ocular disturbances: Child turns head to one side to compensate for defective vision Clinical Features Head of the patient is tilted towards the affected side while the chin points to the other side Sternocleidomastoid muscle is prominently seen In the later stages, the patient may develop facial asymmetry and macular disturbances in the eye Among the acquired causes of torticollis, spasmodic muscle contraction of the sternocleidomastoid is the most common cause Management Conservative Initially conservative line of treatment is observed This consists of nonsteroidal anti-inflammatory drugs (NSAIDs), muscle relaxants drugs, etc Causes • Congenital: (See Chapter 35, Congenital Disorders for description) • Infective: Tuberculosis of cervical spine, acute respiratory tract infection, etc • Traumatic Sprain, dislocation and fracture of the cervical spine • Myositis or fibromyositis of sternocleidomastoid, exposure to cold causes myositis • Spasmodic: Painful, persistent or intermittent sternomastoid muscle contraction Fig 29.1: Features of wryneck 374 Nontraumatic Orthopedic Disorders Physiotherapy like ultrasound, heat, massage is advocated In acute pain, the patient is encouraged to wear a collar Gradual neck stretching exercises are advised once the acute symptoms subside Surgical Management is advised after the failure of conservative treatment It consists of release of sternomastoid muscle from its clavicular attachment as in congenital torticollis and intradural section of both spinal accessory and three cervical roots in cases of torticollis due to spasmodic or neural causes THORACIC OUTLET SYNDROME The space at the thoracic outlet or inlet when it is less than adequate, subjects the neurovascular structures seeking to gain entry into the upper limbs via this space, to undue pressure (Fig 29.2) The blame for the neurovascular complaints should be placed at the doorstep of the decreased space and not at the structures producing the problems This syndrome results from the compression of neurovascular bundle comprising of subclavian artery and vein, axillary artery and vein and brachial plexus at the thoracic outlet Thoracic outlet is a space between the first rib, clavicle and the scalene muscles The above structures are liable to be compressed (Fig 29.3) when this space gets narrowed either due to hypertrophy of the existing muscles or due to any other cause like congenital, trauma, etc Fig 29.2: Anatomy of the thoracic outlet Fig 29.3: Abnormal scalene muscle insertion causing compression of neurovascular structures Sites of Compression The sites of compression could be either supraclavicular, subclavicular or infraclavicular Supraclavicular: Interscalene triangle between the anterior scalene muscles Subclavicular: Interval between the second thoracic rib, clavicle and subclavius Infraclavicular: Beneath an enclosure formed by the coracoid process, pectoralis minor, and costocoracoid membrane Rare Cause Scissor-like encirclement of axillary artery by the median nerve Contributing Factors Dynamic Factors Arm when in full abduction pulls up the artery by 180° causing compression in the short retroclavicular space Regional Conditions of the Neck Static Factors Tests Vigorous occupation: Increases the muscle bulk and thereby decreases the space Intermittent Claudication Test Inactive occupation: Decreases the muscle bulk and thereby increases the space Congenital: Cervical rib decreases the interscalene space and thereby decreases the retroclavicular space Traumatic: Malunion or nonunion of fracture clavicle Arteriosclerosis Anomalies of the first thoracic rib Miscellaneous • Tumor arising from the upper lobe of the lung • Cervicothoracic scoliosis • Abnormal variations of the scalene muscles Clinical Features Obviously, this syndrome poses two major problems The first one relates to the compression of the major vessels and secondly to the compression of the nerves The first problem has a definite clinical entity, while the second one presents a vague picture and makes an accurate diagnosis difficult Vascular Problems Here the compression could be arterial or venous During the arterial compression, which is mild in the early stages the patient complains of numbness of the whole arm with rapid fatigue during overhead exercises If the compression is significant, the patient will complain of cold, cyanosis, pallor and Raynaud’s phenomenon Venous compression leaves the limb swollen and discolored after exercises, which disappears slowly with rest The arm is abducted and elevated and fingers are exercised The inference: • If pain develops after minute; it is negative (normal) • If pain develops before minute; the test is positive Compression of subclavian artery in the neck: Radial pulse decreases Allen’s Test To determine the adequacy of radial and ulnar arteries, by compressing each one at a time and checking for adequacy Costoclavicular Maneuvers The patient’s shoulder is braced down and back The reproduction of the symptoms, change in the radial pulse, bruit heard in infraclavicular area are the positive findings Provocative Tests Adson’s test: The radial pulse is felt and the patient is asked to take a deep breath and turn the head to the same side (Fig 29.4B) Decrease in the radial pulse indicates positive test Wright’s test: The same maneuver as above but the head is tilted towards the opposite side (Fig 29.4A) It should be noted that thoracic outlet syndrome is a diagnosis of exclusion First, the cervical pathology Neurogenic Problems This involves C8 T1 segment (Klumpke’s paralysis) Patients complain of par esthesia along the medial aspect of the arm, hand, little and ring fingers There is weakness of the hand also 375 Fig 29.4: Methods of performing: (A) Wright’s test, (B) Adson’s test 376 Nontraumatic Orthopedic Disorders should be excluded and later the above tests should be performed as the initial screening procedures Complications Subclavian artery compression → results in poststenotic dilatation → stasis favors thrombosis → the thrombi break and migrate distally causing embolization → these results in the distal artery blockade causing ischemia and gangrene of the upper limbs Investigations X-ray neck: To rule out intrinsic causes like cervical spondylosis, cervical rib, etc Nerve conduction studies: Difficult to determine the nerve conduction velocity through the thoracic outlet, but its biggest value is to rule-out problems like entrapment, e.g ulnar nerve at elbow, wrist, etc Treatment • Conservative treatment: Consists of rest, physiotherapy, exercises like shoulder shrugging, etc • Surgical treatment CERVICAL RIB Cervical rib problem is akin to the story of the “Return of the Prodigal Son” However, unlike the chastened prodigal son, cervical rib returns to torment the unfortunate victim! It is a rib arising from the 7th cervical vertebra, rarely 6th and 5th cervical vertebra Incidence: It is 0.46 percent Nearly 50 percent of those are unilateral Side: It is more frequent on the right side Developmental Factors In the embryo nerves larger than the ribs interfere with the development of the costal process When brachial plexus is prefixed, well-developed 4th cervical root and small 2nd thoracic root offer little resistance to the costal process at the 7th cervical root In postfixed brachial plexus, well-developed 1st thoracic root offers resistance to costal process of 7th cervical root Obviously, cervical rib is more common in prefixed variety Types Indications: Gangrene and poststenotic dilatation Four varieties are described: Methods Complete: The cervical rib reaches up to the first thoracic rib • Removal of the first thoracic rib: This is the most effective treatment as it deals with both supraclavicular and infraclavicular etiological factors in this syndrome • Removal of cervical rib: If this is the cause of compression • Scalenotomy is indicated in scalenus anticus syndrome Quick facts • Sites of compression could be supra, sub, or infraclavicular • Clinical manifestation could be neural, vascular or both • Diagnosis is usually by exclusion and the screening test helps • Excision of the first thoracic rib is the most effective surgical procedure Bulbous end: In this, the cervical rib has a bulbous end Tapering end: In this, the cervical rib tapers Fibrous band: In this, the rib is represented by a thick fibrous band Pathological Anatomy The neurovascular structures, the brachial plexus and subclavial vessels are up by the cervical rib that is inserted into the scalene tubercle of the 1st rib space Pronounced drooping of the shoulder in women after middle age, trauma, unusual lifting operations, acute illness make the muscles weak, pulling the plexus and artery distally giving rise to symptoms Regional Conditions of the Neck 377 the first thoracic nerve root The patient complains of paresthesia along the medial aspect of the arm, hand and little fingers There is weakness of the hand muscles also Radiograph X-ray of the neck (AP and lateral views) helps to detect the presence of cervical rib (Fig 29.5) However, the absence of the rib on the X-ray does not rule out the possibility of the presence of cervical rib Fig 29.5: Radiograph showing unilateral cervical rib Clinical Features Cervical rib with local symptoms: Show presence of a lump and tenderness in the supraclavicular fossa Cervical rib with vascular symptoms: This gives rise to pain in the upper limbs, temperature and color changes, radial pulse is feeble or absent and a feeling of numbness is present Cervical rib with nerve pressure symptoms: The nerve pressure symptoms are due to the angulations of Treatment In mild cases, sling exercises often help In more severe cases, scalenotomy (resection of scalenus anterior muscle) may be required and is successful in 70 percent of the cases In troublesome cases, removal of the cervical rib or the first rib surgically with its periosteum to prevent its regeneration is advocated CERVICAL DISK SYNDROMES This has been dealt in section on Geriatric Orthopedics 30 • • • Regional Conditions of the Upper Limb Regional conditions of the shoulder – Frozen shoulder – Rotator cuff lesions – Rotator cuff tears – Deltoid contracture Regional conditions of the elbow – Tennis elbow – Golfer’s elbow – Olecranon bursitis Regional conditions of the wrist and hand – De Quervain’s disease – Trigger fingers and thumb – Ganglia – Dupuytren’s contracture – Carpal tunnel syndrome – Compound palmar ganglion REGIONAL CONDITIONS OF THE SHOULDER FROZEN SHOULDER (Syn: Periarthritis, Adhesive Capsulitis) Paradoxically shoulder joint privileged as the most mobile joint in the body has its nemesis because of this very advantage Its mobility makes it very vulnerable to problems, which ultimately “freezes” its movements Unable to come to terms with the paucity of liberal movements hitherto enjoyed, the hapless patient resigns himself or herself to suffer the agony in silence! It is defined as a clinical syndrome characterized by painful restriction (Figs 30.1A and B) of both active and passive shoulder movements due to causes within the shoulder joint or remote (other parts of the body) History Dupley first described it in 1872 and called it as humeroscapular periarthritis In 1934, Codman coined Figs 30.1A and B: Test to detect frozen shoulder (note the distance between the thumbs): (A) Frozen shoulder, (B) Normal the term Frozen shoulder, and in 1945, Neviaser gave the name adhesive capsulitis Epidemiology of Frozen Shoulder • • • • • Incidence in general population is percent Incidence in diabetics is 10-35 percent More common in females than males Mean age is 40-60 years Bilateral 12 percent Causes The causes for frozen shoulder could be: • Primary: Here the exact cause is not known and it could be idiopathic • Secondary: According to Lumberg, the secondary causes could be: – Shoulder causes: Problems directly related to shoulder joint which can give rise to frozen shoulder are tendonitis of rotator cuff, bicipital tendinitis, fractures and dislocations around the shoulder, etc Regional Conditions of the Upper Limb 379 Figs 30.2A and B: (A) Normal capsular pattern, (B) shrinkage of the capsule in frozen shoulder – Nonshoulder causes: Problems not related to shoulder joint like diabetes, cardiovascular diseases with referred pain to the shoulder, which keeps the joint immobile, reflex sympathetic dystrophy, frozen hand shoulder syndrome, a complication of Colles’ fracture, can all lead to frozen shoulder The reason could be prolonged immobilization of the shoulder joint due to referred pain, etc Pathology • During abduction, and repeated overhead activities of the shoulder, long head of biceps and rotator cuff undergo repeated strain This results in inflammation, fibrosis and consequent thickening of the shoulder capsule, which results in loss of movements (Figs 30.2A and B) If the movements are continued, then the fibrosis gradually breaks, movements return but never come back to normal • Prolonged activity causes small scapular and biceps muscles to waste faster, load on joint increases and degenerative changes sets in Capsule is fibrosed and shoulder movements are decreased Clinical Features A patient with frozen shoulder clinically presents as follows: • Decreased range of both active and passive shoulder movements • The patient demonstrates a capsular pattern of movement restrictions (i.e external rotation > abduction > internal rotation) • Pain is noted at the end stage of stretch Fig 30.3: A patient of frozen shoulder is unable to the daily routine activities like these • Accessory joint play is reduced • Resistive tests are generally pain free in the available range of motion • Patient is unable to routine daily activities like combing the hair, in case of women wearing the buttons of their blouse, (Fig 30.3), doing overhead activities, etc Facts you must know Diagnosis of frozen shoulder is primarily by clinical examination which records capsular type of restriction of both the active and passive range of motion of the shoulder Clinical Stages There are three classical stages in frozen shoulder, according to Reeves: Stage I (stage of pain): Patient complains of acute pain, decreased movements, external rotation greatest followed by loss of abduction and then forward flexion Internal rotation is least affected This stage lasts for 10-36 weeks Note: Pain in frozen shoulder does not radiate below the elbow (Fig 30.4) Stage II (stage of stiffness): In this stage, pain gradually decreases and the patient complains of stiff shoulder Slight movements are present This lasts for 4-12 months Stage III (stage of recovery): Patient will have no pain and movements would have recovered but will never be regained to normal It lasts for months to years 380 Nontraumatic Orthopedic Disorders Stage II: In this stage, since the pain will have reduced considerably, exercises both active and passive are gradually begun followed by physiotherapy, ultrasound, heat and shoulder wheel exercises The role of manipulation of the shoulder is controversial but can be attempted under general anesthesia in this stage Stage III: In this stage, active and passive exercises, physiotherapy consisting of short wave diathermy, ultrasound, etc are continued Treatment pearls Fig 30.4: Region of distribution of pain in frozen shoulder • Exercises are most effective than modalities, drugs and steroid injection • Mobilization techniques are the other effective method • Traditional manipulation under GA is a previous successful method • Traditional manipulation under GA is more successful than traction manipulation • Arthroscopic distension (Bruisement technique): This helps to increase ROM after several weeks or months • Arthroscopic releases: This is indicated in recalcitrant cases where the above measures have all failed ROTATOR CUFF LESIONS This includes both rotator cuff tears and impingement syndrome Fine adjustments of the humeral head within the glenoid is achieved by coordinated activity of four interrelated muscles (Fig 30.6) arising from the scapula and is called rotator cuff Note: Rotator cuff comprises supraspinatus, infraspinatus, subscapularis and teres minor (Mnemonic SITS) Fig 30.5: Radiographs showing features of frozen shoulder Radiology X-ray of the shoulder is usually normal; but in a few cases, ‘sclerosis’ may be seen on the outer edge of greater tuberosity (Golding’s sign) (Fig 30.5) Treatment Stage I: In this stage, long acting once a day NSAIDs are usually preferred as this condition usually runs a long course (10-36 weeks) Intra-articular steroids may help to provide transient relief of pain only Fig 30.6: Muscles of the rotator cuff Regional Conditions of the Upper Limb 381 Figs 30.7A and B: Anatomy of the shoulder joint (internal structures): (A) Shoulder joint opened (lateral view) (B) Coronal section through shoulder joint Role of Rotator Cuffs SUPRASPINATUS TENDINITIS In the movement of abduction, supraspinatus steadies the head from above, infraspinatus depresses the head, and subscapularis steadies the head in front paralleling the action of the infraspinatus This combined action allows the deltoid muscle to swing up the arm from a steady fulcrum irrespective of the position of the scapula (Figs 30.7A and B) Among the various causes mentioned above, supraspinatus tendinitis is the one that is commonly encountered and this gives rise to the impingement syndrome Impingement occurs beneath the coracoacromial arch The most vulnerable structures for impingement between the undersurface of the acromion and the head of the humerus are the greater tuberosity, the overlying supraspinatus tendon (Fig 30.8) and the long head of biceps The major site of compression is anterior to the angle of the acromion Hence, the proper term is anterior impingement syndrome or painful arc syndrome (Fig 30.9) Impingement Syndrome It is a problem, which is commonly associated with supraspinatus tendon Other causes like bicipital tendonitis, and intraspinatus tendonitis, subacromial bursitis, etc may give rise to rotator cuff problems, but they are not that common (see box) Causes of impingement syndrome • • • • • • • • Complete or partial rupture of rotator cuff Supraspinatus tendonitis Calcific deposits Subacromial bursitis Subdeltoid bursitis Periarthritis Bicipital tenosynovitis Fracture greater trochanter Fig 30.8: Supraspinatus tear 382 Nontraumatic Orthopedic Disorders • Overhead sports and athletes like throwers, swimmers, tennis players, etc • Degenerative etiology is the major cause • Dislocation of shoulder joint in 40-60 years of age • About 2/3rd cases are seen in male population Classification of Rotator Cuff Tears Fig 30.9: Anterior impingement syndrome (According to American Arthroscopic Orthopedics) • Small tear (< cm) • Medium tear (1-3 cm) • Large tears (3-5 cm) Neer’s stages of impingement syndrome Clinical Tests • • • • Special shoulder tests that are helpful in diagnosing rotational, cuff tears and the impingement syndrome, is the painful arc sign (It is 81% specific) There are innumerable other tests but is outside the scope of this book Edema stage Tendinitis and fibrositis Rotator cuff tears and rupture of biceps tendon Bone changes Types of Impingement Syndrome Primary: Here impingement occurs beneath the coracoacromial arch and is due to subacromial overloading Secondary: This is due to relative decrease in the subacromial arch and is due to microinstability of the glenohumeral joint or scapulothoracic instability Posterior (Internal): Seen in overhead athletes like throwers, swimmers and tennis players Here the supra- and infraspinatus tendons are pinched between the posterior and superior aspects of the glenoid when the arm is in elevated and externally rotated position Among the three, primary impingement is more common ROTATOR CUFF TEARS Note: Incidence of rotator cuff tear, less than 70 years— 30 percent; 71-80 years—60 percent; more than 89 years— 70 percent About Rotator Cuff Tears The causes for rotator cuff tears, partial or full, are as follows: • Age > 40 years • Occupations requiring repetitive and excessive overhead movements Interesting facts Do you know the clinical facts leading to the diagnosis of RCL tear? • Age > 40 years • Previous history of minor trauma • Degenerative changes on the X-rays • Various clinical tests How accurate are these tests? There are 91 percent sensitive and 75 percent specific Pearl: Clinical tests are more accurate and cost effective than a battery of investigations in diagnosing an RCL Clinical Features All patients with impingement syndrome have similar clinical features like pain, swelling, limitation of shoulder movements, muscle atrophy (supraspinatus and infraspinatus), and tenderness over the greater tuberosity, etc The following grades are described in anterior impingement syndrome Grade I: This is common in young adults and athletes in the age group of 18-30 years Due to overstress and repeated overhead activity, impingement occurs and supraspinatus is inflamed The painful arc appears here (Fig 30.11) Grade II: This is seen in age group of 40-45 years and may be due to supraspinatus tendinitis or Index A Achondroplasia 517 clinical features 517 radiograph 517 treatment 518 Acute dislocation of knee 263 Acute dislocation of patella 263 treatment 263 Acute respiratory distress
