Physical Examination of the Shoulder Physical Examination of the Shoulder General setup Patient will be examined in both the seated and supine position so exam table needed 360 degree access to patient Expose neck and both shoulders (for comparison); female in gown or sports bra Inspection Skin and tissues: evaluate for bruising, swelling, prior scars, etc. Evaluate for muscle atrophy o Chronic RTC disease o Chronic scapular notch cysts causing nerve impingement o Chronic brachial plexopathy Evaluate for deformity: biceps (popeye deformity), AC joint, SC joint, clavicle, chest wall (pectoralis injury) Evaluate scapular position/winging (wall-pushups will expose this better if suspected) o Marked winging indicates weakness of serratus anterior (long thoracic nerve) o Observe how the scapula tracks with active forward elevation and active abduction . Medial border winging laterally is common cause of shoulder impingement pain: Tx with PT for scapular stabilizer strengthening to improve mechanics and decrease impingement pain Palpation for tenderness/crepitus AC joint SC joint Biceps groove Sub-acromial space/bursa Posterior glenohumeral joint line Superior and medial border of scapula- bursitis/snapping scapula Physical Examination of the Shoulder Neck Range of motion Scoliosis/kyphosis Tenderness Spurling’s sign – Passive head rotation toward affected side, with neck extension and compression o Positive if dermatomal radicular pain occurs Shoulder shrug-trapezius strength (spinal accessory nerve-cranial nerve XI) Thoracic outlet syndrome examination: o Roos test – Hands held overhead, repeated hand clasps for 1 minute . Positive if arm symptoms are reproduced o Adson test – Arm extended with neck extension and rotation toward the affected side . Positive if loss of radial pulse or symptoms reproduced with inhaling Neurologic exam C5- Deltoid and biceps strength; lateral deltoid sensation; biceps reflex C6- Biceps and wrist extension strength; lateral forearm/thumb sensation; brachioradialis reflex C7- Triceps strength; middle finger sensation; triceps reflex C8- Interossei strength; ulnar forearm/5th finger sensation; no reflex Shoulder range of motion (bilateral) Six basic shoulder motions are: Elevation (scaption), abduction, adduction, external rotation, internal rotation, extension If stiffness is suspected with active ROM, supine position or sitting position while stabilizing the scapula is more accurate information about true glenohumeral joint range of motion. o Limited AROM and PROM . Causes: arthritis, frozen shoulder, deformity/facture o Limited AROM but normal PROM . Causes: pain, functional weakness Physical Examination of the Shoulder Strength evaluation Rotator cuff testing: o Supraspinatus . Jobes test Arm abduction to 90 degrees in scapular plane (30 degrees FE), thumb pointing down, patient resists downward force on arm o If patient has a true drop arm = supraspinatus test o If patient has pain and/or weakness but not a complete drop arm = supraspinatus tear vs. subacromial bursitis . Drop sign Same position as Jobes test above, but ask patient to lower arm slowly o If arm drops to their side = supraspinatus tear/dysfunction o Infraspinatus . ER weakness with elbow at side and neutral rotation . ER lag sign Passively ER arm with elbow at side, and ask patient to maintain ER position o Positive for infraspinatus tear if patient can’t hold ER position o Subscapularis . Bear hug (superior subscapularis) – most specific Affected side hand to opposite shoulder, patient resists examiner bringing hand off of shoulder o Positive if pain or weakness . Supine Napolean test (superior subscapularis) – most sensitive Supine, examiner holds patients hand flat on abdomen and stabilizes shoulder, patient actively brings elbow forward o Positive if patient can’t bring elbow anterior to plan of body . Note: not reliable test in patients who have lost significant passive IR due to OA or frozen shoulder (ie. must have normal passive IR for test to be accurate) Physical Examination of the Shoulder Strength evaluation, Subscapularis (Continued) . Napolean Belly press (superior subscapularis) palm of hand against abdomen, internal rotation with elbow anterior to plane of body o Positive if elbow can’t reach or be maintained anterior to plane of body while palm remains flat on abdomen (patient may cheat by palm coming off of abdomen) . Lift off (inferior subscapularis) Dorsum of hand placed on upper lumbar spine o Positive if patient unable to lift hand off of lumbar spine against resistance o Can modify test by passively lifting hand away from lumbar spine and releasing . Positive if patient can’t maintain hand off lumbar spine o Teres Minor . ER strength tested at 90 degrees abduction (in scapular plane ie. scaptation) and 90 degrees ER . Hornblower’s sign – positive when arm drifts into IR when put into 90 degrees scaptation and 90 degrees ER Can grade strength out of 5 o 5/5 – full o 4/5 – weakness detected o 3/5 - able to hold against gravity only o 2/5 – can’t hold against gravity o 1/5 – visible muscle contraction only o 0/5 – no muscle contraction Test general upper extremity strength if suspect neurologic process (along with sensation and reflexes) Physical Examination of the Shoulder Shoulder stability evaluation Asses for generalized ligament laxity with Beighton scale: 4/9 or greater score suggests hypermobility syndrome: o Thumb-forearm test 0-2 points o 5th finger hyperextension beyond 90 degrees 0-2 points o Elbow recurvatum beyond 10 degrees 0-2 points o Knee recurvatum beyond 10 degrees 0-2 points o Hands flat on floor with knees extended 0-1 points Sulcus test for inferior capsular laxity (often positive in multi-directional instability/rotator interval disease (seated) o Patient is seated, arm relaxed, examiner pulls down on arm and looks for sulcus off lateral acromion . >1cm sulcus that stays with ER at side positive for pathologic rotator interval lesion Anterior and posterior load-shift test (supine) o 40 degrees abduction, 90 degrees FE; examiner applies axial load to the arm along with anterior/posterior forces . Positive if increased translation to contralateral side Anterior and posterior apprehension tests (supine) o 90 degrees abduction, >90 degrees ER (maximum) . Positive if patient experiences apprehension/feelings of instability (typically anterior) . Relocation test – posterior force on humeral head in position of apprehension Positive if patient’s apprehension is relieved Jerk test (posterior instability) o Sitting position, 90 degrees FE and 90 IR; posteriorly directed force in this position . Positive if maneuver causes a “clunk” or pain Physical Examination of the Shoulder Special tests Hawkin’s Test – shoulder impingement Patient Position Sitting or standing. Examiner Position Standing lateral or slightly forward of the involved shoulder. Procedure Position the shoulder in 90° flexion (in the scapular plane) and elbow in 90° flexion. Support underneath the elbow and grasp the distal forearm on the dorsal surface. Internally rotate the shoulder until pain or limit of range of motion is achieved. Positive Test Pain or limitation of range of motion due to pain. Indicates pathology of the rotator cuff group (particularly the supraspinatus) or long head of biceps tendon = impingement of these structures under the acromion process. Neer’s Test – shoulder impingement Patient Position Sitting or standing. Examiner Position Standing lateral or slightly behind patient. Procedure Stabilize scapula with one hand, rotate arm in thumb down position and forward elevate arm. Positive Test Pain or decreased ROM due to pain. Pain localizes along lateral subacromial space. Physical Examination of the Shoulder Cross-body Adduction Test – AC joint Patient Position Seated or standing. Examiner Position At side or behind patient. Procedure Position the arm at 90° flexion and then adduct across front of body. Positive Test Localized pain at AC joint. Speed’s Test – Biceps Patient Position Sitting or standing, elbow extended, palm towards the ceiling, with shoulder slightly flexed. Examiner Position Lateral to patient. Palpate the bicipital groove with one hand. Then place other hand over top of distal forearm. Procedure Instruct the patient to move arm upward against your resistance, moving through the full range of motion. Positive Test Pain on the biceps tendon in the bicipital groove or pain in the superior portion of the glenohumeral joint. Indicates inflammation of the biceps tendon, or possible biceps tendinopathy (SLAP lesion) Physical Examination of the Shoulder O’Driscoll Test – SLAP test Patient Position Seated or standing.

Yergason’s Test Patient Position Sitting or standing, elbow flexed to 90°, and forearm midway between pronation and supination (thumb towards ceiling), humerus alongside trunk. Examiner Position Lateral to patient. Palpate the bicipital groove to orient the patient to the location of pain related to the evaluation. Place other hand over top of distal forearm. Procedure Instruct the patient to actively flex their elbow and supinate their forearm while examiner resists the motion. Positive Test Pain or snapping in the bicipital groove or pain in the superior portion of the glenohumeral joint. Indicates tear or laxity of bicipital tendon in groove, or possible bicep tendinopathy (SLAP lesion). Physical Examination of the Shoulder O’Brien’s Test – SLAP lesion Patient Position Seated or standing. Examiner Position Behind or beside patient. Procedure Position arm at 90° of flexion, adduct 10° past neutral, with thumbs down. Have patient elevate arm against resistance. Positive Test Pain at anterior superior shoulder.

  • The Branching and Innervation Pattern of the Radial Nerve in the Forearm: Clarifying the Literature and Understanding Variations and Their Clinical Implications
    diagnostics Article The Branching and Innervation Pattern of the Radial Nerve in the Forearm: Clarifying the Literature and Understanding Variations and Their Clinical Implications F. Kip Sawyer 1,2,* , Joshua J. Stefanik 3 and Rebecca S. Lufler 1 1 Department of Medical Education, Tufts University School of Medicine, Boston, MA 02111, USA; rebecca.lufl[email protected] 2 Department of Anesthesiology, Stanford University School of Medicine, Stanford, CA 94305, USA 3 Department of Physical Therapy, Movement and Rehabilitation Science, Bouve College of Health Sciences, Northeastern University, Boston, MA 02115, USA; [email protected] * Correspondence: [email protected] Received: 20 May 2020; Accepted: 29 May 2020; Published: 2 June 2020 Abstract: Background: This study attempted to clarify the innervation pattern of the muscles of the distal arm and posterior forearm through cadaveric dissection. Methods: Thirty-five cadavers were dissected to expose the radial nerve in the forearm. Each muscular branch of the nerve was identified and their length and distance along the nerve were recorded. These values were used to determine the typical branching and motor entry orders. Results: The typical branching order was brachialis, brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, supinator, extensor digitorum, extensor carpi ulnaris, abductor pollicis longus, extensor digiti minimi, extensor pollicis brevis, extensor pollicis longus and extensor indicis. Notably, the radial nerve often innervated brachialis (60%), and its superficial branch often innervated extensor carpi radialis brevis (25.7%). Conclusions: The radial nerve exhibits significant variability in the posterior forearm. However, there is enough consistency to identify an archetypal pattern and order of innervation. These findings may also need to be considered when planning surgical approaches to the distal arm, elbow and proximal forearm to prevent an undue loss of motor function.

  • Anatomical, Clinical, and Electrodiagnostic Features of Radial Neuropathies
    Anatomical, Clinical, and Electrodiagnostic Features of Radial Neuropathies a, b Leo H. Wang, MD, PhD *, Michael D. Weiss, MD KEYWORDS Radial Posterior interosseous Neuropathy Electrodiagnostic study KEY POINTS The radial nerve subserves the extensor compartment of the arm. Radial nerve lesions are common because of the length and winding course of the nerve. The radial nerve is in direct contact with bone at the midpoint and distal third of the humerus, and therefore most vulnerable to compression or contusion from fractures. Electrodiagnostic studies are useful to localize and characterize the injury as axonal or demyelinating. Radial neuropathies at the midhumeral shaft tend to have good prognosis. INTRODUCTION The radial nerve is the principal nerve in the upper extremity that subserves the extensor compartments of the arm. It has a long and winding course rendering it vulnerable to injury. Radial neuropathies are commonly a consequence of acute trau- matic injury and only rarely caused by entrapment in the absence of such an injury. This article reviews the anatomy of the radial nerve, common sites of injury and their presentation, and the electrodiagnostic approach to localizing the lesion. ANATOMY OF THE RADIAL NERVE Course of the Radial Nerve The radial nerve subserves the extensors of the arms and fingers and the sensory nerves of the extensor surface of the arm.1–3 Because it serves the sensory and motor Disclosures: Dr Wang has no relevant disclosures.

  • Mallet Finger Advice Information for Patients Page 2 This Information Leaflet Is for People Who Have Had a Mallet Finger Injury
    Oxford University Hospitals NHS Trust Emergency Department Mallet finger advice Information for patients page 2 This information leaflet is for people who have had a mallet finger injury. It describes the injury, symptoms and treatment. What is a mallet finger? A mallet finger is where the end joint of the finger bends towards the palm and cannot be straightened. This is usually caused by an injury to the end of the finger which has torn the tendon that straightens the finger. Sometimes a flake of bone may have been pulled off from where the tendon should be attached to the end bone. An X-ray will show whether this has happened. In either case, without the use of this tendon the end of your finger will remain bent. What are the symptoms? • pain • swelling • inability to straighten the tip of your finger. page 3 How is it treated? Your finger will be placed in a plastic splint to keep it straight. The end joint will be slightly over extended (bent backwards). The splint must be worn both day and night for 6 to 8 weeks. This allows the two ends of the torn tendon or bone to stay together and heal. The splint will be taped on, allowing you to bend the middle joint of your finger. The splint should only be removed for cleaning (see below). Although you can still use your finger, you should keep your hand elevated (raised) in a sling for most of the time, until the doctor sees you in the outpatient clinic. This will help to reduce any swelling and pain.

  • Palm Reading
    Palm Reading Also known as palmistry or chiromancy, palm reading is practiced all over the world with roots in Indian astrology and gypsy fortune-telling. The objective is to evaluate a person’s character and aspects of their life by studying the palm of their hand. There is no substantiate evidence of correlation between palm features and psychological traits; palm reading is for entertainment purposes. Getting Started Which hand to read? There are two main practices: For males, the left hand is what you’re born with, and the right is what you’ve accumulated throughout your life. For females, it’s the opposite. Your dominant hand (the hand you use most often) determines your future and your other, non-dominant hand, is used to determine the past or hidden traits Take these into consideration when choosing which hand to read. Reading the Primary Lines of your Hand 1. Interpret the Heart Line This line is believed to indicate emotional stability, romantic perspectives, depression, and cardiac health. Begins below the index finger = content with love life Begins below the middle finger = selfish when it comes to love Begins in-between the middle and index fingers = caring and understanding Is straight and short = less interest in romance Touches life line = heart is broken easily Is long and curvy = freely expresses emotions and feelings Is straight and parallel to the head line = good handle on emotions Is wavy = many relationships, absence of serious relationships Circle on the line = sad or depressed Broken line = emotional trauma 2. Examine the Head Line This line represents learning style, communication style, intellectualism, and thirst for knowledge.

  • Unusual Cubital Fossa Anatomy – Case Report
    Anatomy Journal of Africa 2 (1): 80-83 (2013) Case Report UNUSUAL CUBITAL FOSSA ANATOMY – CASE REPORT Surekha D Shetty, Satheesha Nayak B, Naveen Kumar, Anitha Guru. Correspondence: Dr. Satheesha Nayak B, Department of Anatomy, Melaka Manipal Medical College (Manipal Campus), Manipal University, Madhav Nagar, Manipal, Karnataka State, India. 576104 Email: [email protected] SUMMARY The median nerve is known to show variations in its origin, course, relations and distribution. But in almost all cases it passes through the cubital fossa. We saw a cubital fossa without a median nerve. The median nerve had a normal course in the upper part of front of the arm but in the distal third of the arm it passed in front of the medial epicondyle of humerus, surrounded by fleshy fibres of pronator teres muscle. Its course and distribution in the forearm was normal. In the same limb, the fleshy fibres of the brachialis muscle directly continued into the forearm as brachioradialis, there being no fibrous septum separating the two muscles from each other. The close relationship of the nerve to the epicondyle might make it vulnerable in the fractures of the epicondyle. The muscle fibres surrounding the nerve might pull up on the nerve and result in altered sensory-motor functions of the hand. Since the brachialis and brachioradialis are two muscles supplied by two different nerves, this continuity of the muscles might result in compression/entrapment of the radial nerve in it. Key words: Median nerve, cubital fossa, brachialis, brachioradialis, entrapment INTRODUCTION The median nerve is the main content of and broad tendon which is inserted into the cubital fossa along with brachial artery and ulnar tuberosity and to a rough surface on the biceps brachii tendon.

  • Stretching and Positioning Regime for Upper Limb
    Information for patients and visitors Stretching and Positioning Regime for Upper Limb Physiotherapy Department This leaflet has been designed to remind you of the exercises you Community & Therapy Services have been taught, the correct techniques and who to contact with any queries. For more information about our Trust and the services we provide please visit our website: www.nlg.nhs.uk Information for patients and visitors Muscle Tone Muscle tone is an unconscious low level contraction of your muscles while they are at rest. The purpose of this is to keep your muscles primed and ready to generate movement. Several neurological causes may change a person’s muscle tone to increase or decrease resulting in a lack of movement. Over time, a lack of movement can cause stiffness, pain, and spasticity. In severe cases this may also lead to contractures. Spasticity Spasticity can be defined as a tightening or stiffness of the muscle due to increased muscle tone. It can interfere with normal functioning. It can also greatly increase fatigue. However, exercise, properly done, is vital in managing spasticity. The following tips may prove helpful: • Avoid positions that make the spasticity worse • Daily stretching of muscles to their full length will help to manage the tightness of spasticity, and allow for optimal movement • Moving a tight muscle to a new position may result in an increase in spasticity. If this happens, allow a few minutes for the muscles to relax • When exercising, try to keep head straight • Sudden changes in spasticity may

  • The Indications for Toe Transfer After ''Minor
    ARTICLE IN PRESS Invited personal view article THE INDICATIONS FOR TOE TRANSFER AFTER ‘‘MINOR’’ FINGER INJURIES F DEL PINAL* From the Institute for Hand and Plastic Surgery, Private Practice, and Mutua Montan*esa, Santander, Spain Toe-to-hand transfer is widely considered to be unjustified for ‘‘minor’’ finger injuries. In this invited personal view article the indications for toe-to-hand transfer for finger amputation and neurocutaneous and major pulp defects are discussed, and a classification of multidigital injury that has both prognostic and decision-making value is presented. In the author’s opinion a toe transfer should always be considered as an option when reconstructing ‘‘minor’’ finger injuries, as it can reproduce significant long-term benefit to the hand and the patient’s sense of well being. The procedure should be carried out in the acute period, not only because it is technically easier and better for hand function, but above all because the surgeon can save structures that will be lost if the transfer is delayed. Journal of Hand Surgery (British and European Volume, 2004) 29B: 2: 120–129 Keywords: microsurgery, toe-to-hand, finger amputation Since the hand is always naked and exposed, even if reconstruction. In this personal view article only the only the fingertip is lost, it presents a very large most ‘‘typical’’ indications will be discussed. The handicap for the patient.
