Physical Esxam Pearls in the Musculoskeletal Exam Frank Caruso MPS, PA-C, EMT-P Skin, Bones, Hearts & Private Parts 2019 Examination Key Points • Area that needs to be examined, gown your patients - well exposed • Understand normal functional anatomy • Observe normal activity • Palpation • Range of Motion • Strength/neuro-vascular assessment • Special Tests General Exam Musculoskeletal Overview Physical Exam Preview Watch Your Patients Walk!! Inspection • Posture – Erectness – Symmetry – Alignment • Skin and subcutaneous tissues – Swelling – Redness – Masses Inspection • Extremities – Size – Deformities – Enlargement – Alignment – Contour – Symmetry Inspection • Muscles – Bilateral symmetry – Hypertrophy – Atrophy – Fasciculations – Spasms Palpation • Palpate bones, joints, and surrounding muscles for the following: – Heat – Tenderness – Swelling – Fluctuation – Crepitus – Resistance to pressure – Muscle tone Muscles • Size and strength affected by the following: – Genetics – Exercise – Nutrition • Muscles move joints through range of motion (ROM). Muscle Strength • Compare bilateral muscles – Strength – Symmetry – Equality – Resistance End Feel Think About It!! • The sensation the examiner feels in the joint as it reaches the end of the range of motion of each passive movement • Bone to bone: This is hard, unyielding – normal would be elbow extension. • Soft–tissue approximation: yielding compression that stops further movement – elbow and knee flexion. End Feel • Tissue stretch: hard – springy type of movement with a slight give – toward the end of range of motion – most common type of normal end feel : knee extension and metacarpophalangeal joint extension. Abnormal End Feel • Muscle spasm: invoked by movement with a sudden dramatic arrest of movement often accompanied by pain - sudden hard – “vibrant twang” • Capsular: Similar to tissue stretch but it does not occur where one would expect – range of motion usually reduced. Abnormal End Feel • Bone to bone: similar to normal bone – to bone but the restriction or sensation of restriction occurs before the normal end of range of movement • Empty: detected when considerable pain is produced by movement - - no real mechanical resistance – acute bursitis – neoplasm. Abnormal End Feel • Springy block: similar to a tissue stretch – occurs where one would not expect it to occur – usually found in joints with menisci. There is a rebound effect – example: would feel a springy block end feel with a torn meniscus of a knee when it is locked or unable to go into full extension (usually no muscle spasm). Range of Motion • Active ROM and passive ROM for each joint and related muscle group • Note – Pain – Limited or spastic movement – Joint instability – Deformity – Contracture Range of Motion • Passive ROM may exceed active ROM by 5 degrees. • Active ROM and passive ROM should be equal in contralateral joints. • Discrepancies may indicate muscle weakness or disorder. • Use goniometer where there is increased or limited ROM. Examination and Findings Equipment • Marking pencil • Goniometer • Tape measure • Reflex hammer • Inclinometer • Mono-filament Goniometry • Is most appropriate for the measurement of medium and small appendicular joints • The examination procedure and techniques used must be consistent Lets Put It All Together!! Joint by Joint My Shoulder Hurts!! Shoulder ICD-9 ICD 10 • Shoulder pain – 719.41 • Shoulder pain – M25.51 • Rotator cuff sprain - • Rotator cuff sprain - 840.4 S43.4 • Rotator cuff tendonitis • Rotator cuff tendonitis – 726.10 – M75.1 Shoulder/Scapula 34 36 Supraspinatus 37 38 Infraspinatus 39 Teres Minor 40 Subscapularis 41 Exam & Findings: Shoulders • Inspect – Shoulder girdle, Clavicle, and Scapula for: – Size – Symmetry – Contour – Dislocation/winging of scapula • Palpate – Sterno-clavicular joint – Acromioclavicular joint – Shoulder muscles – Biceps Groove Exam & Findings: Shoulders • Assess Active and Passive ROM – Forward flexion • The arm is kept straightened and brought upward through the frontal plane, and moved as far as the patient can go above his head. Note: for recording purposes, 0 degrees is defined as straight down at the patient's side, and 180 degrees is straight up Exam & Findings: Shoulders • Assess Active and Passive ROM – External rotation (hands behind head) – The patient is positioned sitting and the elbow is flexed 90 degrees – While the elbow is held against the patient's side, the examiner externally rotates the arm as permitted Exam & Findings: Shoulders • Assess Active and Passive ROM – Extension Exam & Findings: Shoulders • Assess Active and Passive ROM – Abduction Adduction Shoulder Assessment • Several procedures are used to evaluate rotator cuff for impingement or tear―increased pain associated with inflammation or tear • Neer test – Internally rotate and forward flex arm at the shoulder: presses supraspinatus muscle against anteroinferior acromion Shoulder Assessment • Hawkins test – Forward flexing shoulder to 90 degrees, flexing elbow to 90 degrees, and then internally rotating arm to its limit Apley scratch test. The patient attempts to touch the opposite scapula to test range of motion of the shoulder. (Left) Testing abduction and external rotation. (Right) Testing adduction and internal rotation. Supraspinatus examination ("empty can" test). The patient attempts to elevate the arms against resistance while the elbows are extended, the arms are abducted and the thumbs are pointing downward. Infraspinatus/teres minor examination. The patient attempts to externally rotate the arms against resistance while the arms are at the sides and the elbows are flexed to 90 degrees. Subscapular Muscle Testing • Push off • Largest part of the rotator cuff 52 Test Maneuver Diagnosis suggested by positive result Apley scratch Patient touches superior and inferior aspects of opposite Loss of range of motion: rotator cuff test scapula problem Neer's sign Arm in full flexion Subacromial impingement Hawkins' test Forward flexion of the shoulder to 90 degrees and internal Supraspinatus tendon impingement rotation Drop-arm test Arm lowered slowly to waist Rotator cuff tear Cross-arm Forward elevation to 90 degrees and active adduction Acromioclavicular joint arthritis test Apprehension Anterior pressure on the humerus with external rotation Anterior glenohumeral instability test Relocation Posterior force on humerus while externally rotating the arm Anterior glenohumeral instability test Sulcus sign Pulling downward on elbow or wrist Inferior glenohumeral instability Yergason test Elbow flexed to 90 degrees with forearm pronated Biceps tendon instability or tendonitis Speed's Elbow flexed 20 to 30 degrees and forearm supinated Biceps tendon instability or tendonitis maneuver "Clunk" sign Rotation of loaded shoulder from extension to forward flexion Labral disorder Probable Finding diagnosis Scapular winging, trauma, recent viral illness Serratus anterior or trapezius dysfunction Seizure and inability to passively or actively rotate Posterior shoulder dislocation affected arm externally Supraspinatus/infraspinatus wasting Rotator cuff tear; suprascapular nerve entrapment Pain radiating below elbow; decreased cervical range Cervical disc disease of motion Shoulder pain in throwing athletes; anterior Glenohumeral joint instability glenohumeral joint pain and impingement Pain or "clunking" sound with overhead motion Labral disorder Nighttime shoulder pain Impingement Generalized ligamentous laxity Multidirectional instability IMPINGEMENT 55 Patient Symptoms: Impingement • I can’t sleep at night, my shoulder is killing me • It is too painful to raise up my arm • It feels like my bones are rubbing together • My arm is painful and weak • My shoulder, neck and arm are hurting me 56 Exam Summary: • Pain with painful arc maneuver – subacromial impingement • Focal subacromial tenderness • Painless testing of resisted abduction (supraspinatus), external rotation (infraspinatus), adduction ( subscapularis), and elbow flexion (Biceps) • Normal range of motion of the glenohumeral joint • Preserved strength in all directions 57 ROTATOR CUFF TENDONITIS 62 Patient Symptoms: Rotator Cuff Tendonitis • I can’t reach up my back anymore • Whenever I move in certain directions I get a sharp deep pain in my shoulder • My arm feels better by hanging it over the bed 63 Exam Findings: • Focal subacromial tenderness • Subacromial impingement, a positive painful arc test • Positive Flexion Abduction Resistance (FAR) • Normal range of motion of glenohumeral joint • Preserved rotator cuff strength – no gross weakness 64 ADHESIVE CAPSULITIS – FROZEN SHOULDER 65 Patient Symptoms: Adhesive Capsulitis • My shoulder is stiffening up • I can’t reach up over my head • Its getting harder and harder to put my coat on • My shoulder used to be painful, pain has improved by I can’t move it now 66 Exam Summary • Loss of external rotation with elbow at side • Restricted abduction • My shoulder makes this terrible clunking noise • No radiographic evidence of glenohumeral osteoarthritis 67 ROTATOR CUFF TENDON TEAR 69 Patient Symptoms: Rotator Cuff Tear • I have no strength in my shoulder any more • Every time I roll my shoulder , it pops • I can’t sleep on my back any more, There’s this spot of pain over my shoulder blade 70 Exam Summary: • Weakness in testing of rotator cuff muscles • Rule out central lesion • Positive drop arm test • High riding humeral head (older patients) 71 ACROMIO-CLAVICULAR STRAIN/OSTEOARTHRITIS 78 Acromioclavicular Joint(AC) ICD-9 ICD-10 • AC joint pain: 719.41 • AC joint

  • Netter's Musculoskeletal Flash Cards, 1E
    Netter’s Musculoskeletal Flash Cards Jennifer Hart, PA-C, ATC Mark D. Miller, MD University of Virginia This page intentionally left blank Preface In a world dominated by electronics and gadgetry, learning from fl ash cards remains a reassuringly “tried and true” method of building knowledge. They taught us subtraction and multiplication tables when we were young, and here we use them to navigate the basics of musculoskeletal medicine. Netter illustrations are supplemented with clinical, radiographic, and arthroscopic images to review the most common musculoskeletal diseases. These cards provide the user with a steadfast tool for the very best kind of learning—that which is self directed. “Learning is not attained by chance, it must be sought for with ardor and attended to with diligence.” —Abigail Adams (1744–1818) “It’s that moment of dawning comprehension I live for!” —Calvin (Calvin and Hobbes) Jennifer Hart, PA-C, ATC Mark D.

Injury the joint • In younger people - meniscal tears are usually the result of trauma, with a specific injury identified in distributing load during the history. movement Tear of Meniscus Pathology Pathology • Usually, meniscus more likely to tear along its Vertical tear Horizontal tear length than across its width because the Bucket-handle tear usually ‘degenerative’ or due to repetitive minor trauma meniscus consists mainly of circumferential the separated fragment remains attached front complex with the tear pattern lying in many collagen fibres held by a few radial strands. and back planes The torn portion can sometimes displace towards may be displaced or likely to displace • The meniscus is usually torn by a twisting the centre of the joint and becomes jammed If the loose piece of meniscus can be displaced, it between femur and tibia acts as a mechanical irritant, giving rise to force with the knee bent and taking weight. This causes a block to movement with the patient recurrent synovial effusion and mechanical describing a ‘locked knee’ symptoms • In middle life, tears can occur with relatively posterior or anterior horn tears Some are associated with meniscal cysts little force when fibrotic change has the very back or front of the meniscus is It is also suggested that synovial cells infiltrate into the vascular area between meniscus and restricted mobility of the meniscus.

In addition, a systematic review comparing the Thessaly’s test with a long standing test such as the McMurray test has not been previously conducted. Objective: To systematically identify and appraise all empirical studies comparing the diagnostic accuracy of the Thessaly test and McMurray test. Procedure: Eligible studies were identified through a rigorous search of ScienceDirect, CINAHL Plus, Pubmed, PEDro, EMBASE and Cochrane Library from January 2004 until August 2014. Full English reports of studies investigating the accuracy of the Thessaly test and McMurray test. Quality Assessment of Studies of Diagnostic Accuracy (QUADAS) scores were completed on each selected article. Results: The Thessaly test reported to have higher diagnostic accuracy values (61-96%) compared to the McMurray test (56-84%).

  • Knee Pain in Children: Part I: Evaluation
    Knee Pain in Children: Part I: Evaluation Michael Wolf, MD* *Pediatrics and Orthopedic Surgery, St Christopher’s Hospital for Children, Philadelphia, PA. Practice Gap Clinicians who evaluate knee pain must understand how the history and physical examination findings direct the diagnostic process and subsequent management. Objectives After reading this article, the reader should be able to: 1. Obtain an appropriate history and perform a thorough physical examination of a patient presenting with knee pain. 2. Employ an algorithm based on history and physical findings to direct further evaluation and management. HISTORY Obtaining a thorough patient history is crucial in identifying the cause of knee pain in a child (Table). For example, a history of significant swelling without trauma suggests bacterial infection, inflammatory conditions, or less likely, intra- articular derangement. A history of swelling after trauma is concerning for potential intra-articular derangement. A report of warmth or erythema merits consideration of bacterial in- fection or inflammatory conditions, and mechanical symptoms (eg, lock- ing, catching, instability) should prompt consideration of intra-articular derangement. Nighttime pain and systemic symptoms (eg, fever, sweats, night sweats, anorexia, malaise, fatigue, weight loss) are associated with bacterial infections, inflammatory conditions, benign and malignant musculoskeletal tumors, and other systemic malignancies. A history of rash or known systemic inflammatory conditions, such as systemic lupus erythematosus or inflammatory bowel disease, should raise suspicion for inflammatory arthritis. Ascertaining the location of the pain also can aid in determining the cause of knee pain. Anterior pain suggests patellofemoral syndrome or instability, quad- riceps or patellar tendinopathy, prepatellar bursitis, or apophysitis (patellar or tibial tubercle).

  • Physical Examination of the Knee: Meniscus, Cartilage, and Patellofemoral Conditions
    Review Article Physical Examination of the Knee: Meniscus, Cartilage, and Patellofemoral Conditions Abstract Robert D. Bronstein, MD The knee is one of the most commonly injured joints in the body. Its Joseph C. Schaffer, MD superficial anatomy enables diagnosis of the injury through a thorough history and physical examination. Examination techniques for the knee described decades ago are still useful, as are more recently developed tests. Proper use of these techniques requires understanding of the anatomy and biomechanical principles of the knee as well as the pathophysiology of the injuries, including tears to the menisci and extensor mechanism, patellofemoral conditions, and osteochondritis dissecans. Nevertheless, the clinical validity and accuracy of the diagnostic tests vary.

Normal cross more than one joint to allow for shortening ROM varies among individuals and is influenced by over one joint and lengthening over the other during age, gender, body habitus, and whether motion is movement. However, there is potential for a muscle performed actively or passively.1 The type and amount or muscle group to become excessively lengthened of movement that occurs throughout the ROM is or shortened when it crosses more than one joint. If unique to each joint of the body and is dependent a muscle is rendered weak because it is shortened as primarily upon the shape of the articular surfaces. much as it can be as it crosses each joint, it is said to Other factors include the integrity and flexibility of be actively insufficient.
