Shoulder Examination OSCE: A Step-by-Step Guide for Medics

Shoulder Examination OSCE: A Step-by-Step Guide for Medics

The shoulder joint, with its unparalleled range of motion and complex anatomy, frequently presents a diagnostic challenge. For medical students and junior doctors, mastering the shoulder examination is not just about identifying pathology, but also about demonstrating a systematic, patient-centred approach – skills rigorously tested in Objective Structured Clinical Examinations (OSCEs). This comprehensive guide provides a clear, step-by-step methodology to confidently navigate a Shoulder Exam Geeky Medics-style OSCE, ensuring you identify key clinical signs and formulate an accurate assessment. A successful shoulder examination goes beyond rote memorisation; it involves a keen eye, a gentle touch, and an understanding of the underlying anatomy and common pathologies. Remember the foundational components of any musculoskeletal examination: Look, Feel, Move, and Special Tests. This framework serves as an invaluable aide-mémoire, guiding you through each stage and preventing you from feeling lost under pressure.

The Foundational Steps: Preparing for Your Shoulder Exam OSCE

Before you even begin to inspect the shoulder, critical preparatory steps are essential for both patient comfort and OSCE success. These initial interactions set the stage for a professional and thorough examination.

• Hand Hygiene & PPE: Always start by washing your hands thoroughly. Don appropriate Personal Protective Equipment (PPE) if the clinical context requires it.
• Introduction & Consent: Introduce yourself clearly, stating your name and role (e.g., "Hello, my name is [Your Name], and I'm a medical student/junior doctor."). Confirm the patient's name and date of birth to ensure you have the correct individual.
• Explain & Gain Consent: Briefly explain the examination in patient-friendly language, outlining what it will involve (e.g., "I'm going to examine your shoulder, which will involve looking at it, gently feeling around the area, and asking you to move your arm in different directions. Please let me know if you experience any pain at any point."). Always explicitly gain verbal consent to proceed.
• Adequate Exposure & Dignity: The shoulder examination requires optimal exposure. Ask the patient to adequately expose their upper body, typically from the waist up. Crucially, provide a blanket or sheet to cover them when specific areas are not being examined, maintaining their dignity and comfort throughout.
• Patient Positioning: Position the patient standing for the initial inspection phases. This allows for a comprehensive view of their posture, symmetry, and how the shoulder girdle sits naturally.
• Check for Pain: Before initiating any physical contact or movement, ask the patient directly, "Do you have any pain in your shoulder today?" Knowing their baseline pain level is vital for interpreting their responses during the examination.

The "Look" Component: A Keen Eye for Detail

The "Look" phase is your opportunity to gather a wealth of diagnostic information simply by observing. This involves both a general inspection of the patient as a whole and a more focused, closer inspection of the shoulder region.

General Inspection: Contextual Clues

Perform a brief yet comprehensive general inspection of the patient, noting any clinical signs that might suggest an underlying pathology or risk factors:

• Body Habitus: Observe the patient's overall build. Obesity, for instance, significantly increases mechanical load on joints, making it a risk factor for conditions like osteoarthritis.
• Scars: Look for any scars on the upper limbs, torso, or neck. Their location can provide clues about previous surgeries (e.g., rotator cuff repair, AC joint reconstruction) or past trauma.
• Muscle Wasting: Note any generalised or localised muscle wasting. Disuse atrophy can occur secondary to chronic joint pathology, while specific wasting patterns might indicate a lower motor neuron lesion or nerve injury affecting the shoulder muscles.
• Objects or Equipment: Look around and on the patient for any aids or adaptations. A support sling immediately suggests acute shoulder pathology or post-operative recovery. Prescriptions (e.g., analgesia, anti-inflammatories) can offer insights into their current management and pain levels.

Closer Inspection of the Shoulder: A 360-Degree View

Ask the patient to stand and turn slowly in 90-degree increments, allowing you to meticulously inspect the upper limbs from anterior, lateral, and posterior aspects. Remember to compare both shoulders throughout.

• Anterior Inspection: Focus on the front of the shoulder joints and upper limbs:
  • Scars & Bruising: Note the exact location and nature of any scars (e.g., deltopectoral, anterior capsule) or bruising, which can indicate recent trauma or surgery.
  • Asymmetry of the Shoulder Girdle: Look for any obvious discrepancies in shoulder height or position. Causes can range from scoliosis to arthritis, previous fractures, or acute dislocations.
  • Swelling: Identify any unilateral swelling, which may suggest an effusion (fluid in the joint), inflammatory arthropathy, or dislocation.
  • Abnormal Bony Prominence: Palpable or visible abnormalities could indicate a fracture (e.g., clavicular fracture) or an anterior glenohumeral joint dislocation.
  • Deltoid Wasting: Pay close attention to the bulk of the deltoid muscles. Asymmetry or significant atrophy may be due to disuse or an axillary nerve injury.
• Lateral Inspection: Turn the patient to inspect the side profiles of the shoulder joints:
  • Scars: Again, note any lateral scars.
  • Deformity: Look for any abnormal contours or prominences.
  • Scapular Winging: While often more obvious posteriorly, severe scapular winging (medial border of the scapula protruding) due to serratus anterior weakness (long thoracic nerve injury) can sometimes be appreciated laterally.
• Posterior Inspection (Adding Value): The posterior view is crucial for assessing scapular dynamics and specific muscle groups:
  • Scars & Bruising: Any marks posteriorly can signify trauma to the back of the shoulder or spine.
  • Muscle Wasting: Crucially, inspect the supraspinatus and infraspinatus fossae for wasting. Atrophy here strongly suggests rotator cuff pathology (especially chronic tears) or suprascapular nerve entrapment. Compare diligently to the contralateral side.
  • Scapular Position & Symmetry: Observe the resting position of the scapulae. Are they symmetrical? Is one elevated, protracted, or retracted compared to the other? Asymmetry can point to muscular imbalances, spinal issues, or underlying shoulder pathology.
  • Spinal Curvature: Note any signs of scoliosis or kyphosis, which can indirectly affect shoulder mechanics.

The "Feel" and "Move" Components: Palpation and Range of Motion

Once you have thoroughly observed, the next critical steps involve palpation and assessing the shoulder's range of motion. These phases help localise pain and evaluate functional limitations. For a more detailed exploration of these stages, refer to our guide on Mastering Shoulder Exams: Look, Feel, Move & Special Tests.

The "Feel" Component: Palpation

Ask the patient if they are experiencing any pain before you begin palpating. Gently, yet systematically, palpate the key bony landmarks and soft tissues of the shoulder, noting any tenderness, warmth, swelling, or crepitus (a grinding sensation).

• Sternoclavicular Joint: Start medially, assessing for tenderness or swelling.
• Clavicle: Palpate along its entire length.
• Acromioclavicular (AC) Joint: Often a source of pain, particularly after trauma or in degenerative conditions.
• Coracoid Process: Locate this bony prominence.
• Greater Tuberosity of Humerus: The insertion site for most rotator cuff muscles, often tender in impingement or cuff tears.
• Bicipital Groove: Tenderness here can suggest biceps tendonitis.
• Spine of Scapula & Scapular Borders: Palpate for tenderness or deformity.
• Muscles: Gently feel the deltoid, trapezius, and rotator cuff muscles for spasm or tenderness.

The "Move" Component: Range of Motion (ROM)

Assess both active and passive range of motion. Ask the patient to perform specific movements actively, then gently move the limb passively if active movement is limited or painful. Note any pain, stiffness, or compensatory movements. Compare both sides.

• Active ROM:
  • Flexion: Raise arm forwards, overhead.
  • Extension: Extend arm backwards.
  • Abduction: Raise arm out to the side, overhead.
  • Adduction: Move arm across the body.
  • Internal Rotation: Place hand behind the back, reaching upwards.
  • External Rotation: Place hand behind the head, reaching downwards (or elbow flexed to 90 degrees, forearm moves away from body).
• Passive ROM: If active ROM is restricted or painful, gently assess passive ROM. This helps differentiate between muscular weakness/pain (active limited, passive full) and joint stiffness/mechanical block (both active and passive limited).

Unlocking Specifics: Special Tests and What Comes Next

Special tests are targeted manoeuvres designed to identify or rule out specific pathologies that you may have suspected during your "Look," "Feel," and "Move" components.

Special Tests

There are numerous special tests for the shoulder, each targeting particular structures like the rotator cuff, biceps tendon, or joint stability. You'll typically perform a selection of relevant tests based on your initial findings. Examples include:

• Impingement Tests: Neer's Test, Hawkins-Kennedy Test (to assess subacromial impingement).
• Rotator Cuff Tests: Empty Can Test (supraspinatus), External Rotation Lag Sign (infraspinatus/teres minor), Lift-Off Test (subscapularis).
• Biceps Pathology Tests: Speed's Test, Yergason's Test.
• Instability Tests: Apprehension Test (anterior instability), Sulcus Sign (inferior instability).

It's crucial to select only the most pertinent special tests based on your developing differential diagnosis, ensuring you don't overwhelm the patient or exceed time limits in an OSCE.

Completing the Examination

Once you have performed your special tests, it’s good practice to:

• Brief Neurovascular Assessment: In a trauma setting or if neurological symptoms are present, quickly check C5-T1 dermatomes and myotomes, as well as peripheral pulses.
• Thank the Patient: Always thank the patient for their cooperation.
• Re-cover & Reposition: Help them redress and return to a comfortable position.
• Wash Hands: Conclude by washing your hands.
• Summarise Findings: In an OSCE, be prepared to succinctly summarise your key findings and suggest potential differential diagnoses.
