Wrist and Hand Examination

Introduction

1024px-1121 Intrinsic Muscles of the Hand Superficial sin.png

The hand and wrist is form a group of complex, delicately balanced joints which are considered the most active portion of the upper extremity. Optimal overall function is important to so many activities of daily living. A hand and wrist examination done in a structured manner will help to facilitate the most appropriate working diagnosis for treatment. Diagnosing hand and wrist conditions is often difficult and for this reason, bilateral comparison can be useful[1]

Subjective History

Thorough history taking is an important first step in treating the patient. Each physical therapist will develop their own style and technique, but a good interview will include the basic elements discussed below:

  • Mechanism of the injury - How the injury occurred and what was the cause e.g. fall on an outstretched hand
  • Insidious or sudden injury.
  • Handedness, occupation, previous injury and fracture history
  • Location of the pain
  • Presence and location of numbness, pins and needles and/or tingling.
  • Aggravating and relieving factors.
  • Functional limitations.
  • Were any diagnostic test/imaging performed and what were the results?

Objective Examination

Screen Proximal Joints

Screen proximal structures to determine if they are involved in the patient’s clinical presentation. i.e. Cervical joints, Shoulder, Elbow.

Observation

Start by watching this 8 minute video of a wrist and hand examination.

[2]

  • Observe upper extremity as the patient enters the room
    1. Examine hand in function
    2. Deformities
    3. Attitude of the hand
  • Dorsal surface
    1. Hills and Valleys
    2. Height of metacarpal heads
    3. Deformities.
  • Ganglions - Cystic structure that arises from synovial sheath
  • Rheumatoid Arthritis - MCP swelling, Swan neck deformities, Ulnar deviation at MCP joints, Nodules along tendon sheaths.[1] (see R)
  • Muscle wasting due to nerve disfunction
    1. Median Nerve (depending on area impingement)
  • Muscle wasting in the thenar eminence, first three and fingers, and half the fourth fingers on radial side of the hand.
    1. Radial Nerve (depending on area of impingement)
  • Common muscles that are affected by radial nerve entrapment are primarily on the dorsal aspect of the hand.
    1. Ulnar Nerve (depending on area of impingement)
    2. Muscle wasting in the hand for the ulnar nerve occurs primarily in the fifth and half the fourth fingers, in the hypothenar area.

Functional Tests

Goals - to obtain and quantify an asterisk to assess/reassess after the intervention is performed, for example: turning doorknob, holding a key, initial pain-free grip or key grip, opening a jar, turning on tap, lifting saucepan. Grip strength can also be a good reliable tool to use (available cheaply on internet).

Palpation

Wrist (Dorsal to Volar)

Palpation of Hand

  • Bone
    • Metacarpals - 5, Phalanges - 14, (Palpate for swelling, tenderness)
  • Soft tissues
    • 6 Dorsal Compartments – Transport extensor tendons See image at R

1st compartment- De quervains 2nd compartment - Intersection syndrome

Compartment 1 (Most radial) Compartment 2 Compartment 3 Compartment 4 Compartment 5 Compartment 6 (Most ulnar)
Abductor pollicis longus Extensor carpi radialis longus Extensor pollicis longus Extensor indicis Extensor digiti minimi Extensor carpi ulnaris
Extensor pollicis brevis Extensor carpi radialis brevis Extensor digitorum communis

[3]

2 Palmar Tunnels – Transport nerves, arteries, flexor tendons

Palmar Aspect - Pisiform and Hamate, Tunnel of Guyon, Carpal Tunnel, Flexor Carpi Radialis, Flexor Carpi Ulnaris

Palm of Hand

  • Thenar Eminence (3 muscles of thumb, Atrophy seen in carpal tunnel syndrome)
  • Hypothenar Eminance (3 muscles of little finger, Atrophy with ulnar nerve compression)
  • Palmar Aponeurosis (Dupuytren’s Contracture)[1]

Neurologic Assessment

Upper Extremity Nerve Palpation:

Goal To reproduce symptoms if a peripheral nerve entrapment diagnosis is suspected.[4]

To palpate the 3 major nerves of the upper extremity refer to the figure below.

  • Median: Position patient supine, 90 degrees of shoulder abduction and elbow extension. Palpate medially to the bicep (mid humeral). Palpate distally at wrist.
  • Radial: Upper arm (0 degrees of abduction, palpate proximal to the lateral epicondyle), distal radius, and snuffbox
  • Ulnar: Upper arm (medial mid humeral area, shoulder 90 degrees of abduction, elbow 120 degrees of flexion) and cubital tunnel

Reflexes - C5-C7

Myotomes - C5-T1

Dermatomes - C5-T1

Movement Testing

Digit ROM Exercise Handout.jpg

If patient is pain free to end range, the physical therapist may choose to apply overpressure.

  • Wrist
    1. Flexion/Extension
    2. Radial/Ulnar deviation
  • 1st CMC
    1. Extension
    2. Abduction
    3. Opposition
  • Metacarpal-phalangeal (MCP)
    1. Flexion
    2. Extension
    3. Abduction/Adduction
  • Inter-phalangeal (IP)/Distal IP/Proximal IP
    1. Flexion
    2. Extension

Strength Testing

  1. Wrist flexion/extension
  2. Forearm pronation and supination
  3. Grip strength
  4. Key and pinch grip strength

Special Tests

The physical therapist may elect to perform various special tests during the physical examination of an individual with wrist or hand complaints. Below are potential tests that may be utilized categorized by possible diagnosis or tissue involvement.

  • Scaphoid Fracture clinical examination (Anatomical snuff box tenderness; Scaphoid tubercle tenderness; Axial loading of the thumb)

Red Flags

Red Flag Framework Level Concern.JPG

This section deals with screening the patient for possible serious pathologies that could cause wrist or hand pain. These conditions could warrant a referral, or consultation.
Infections

  • Heat
  • Swelling
  • Pain
  • Redness
  • Inflammation

Fracture/dislocation:

Top five physical findings which are most useful in screening for wrist fracture.[5] - Localized tenderness, Pain on active motion, Pain on passive motion, Pain on grip, Pain on supination

Anyone of the above findings associated with a history of trauma should be sent for radiographs

Additional potentially serious conditions

Possible Diagnosis Examples from Examination

Outcome Measures

Conclusion

Hand and wrist complaints are common presentations to physiotherapy clinics. Some practices are special "hand" clinics. Being able to perform a thorough examination is vital. Common acute problems include fractures, tendonitis, and trigger finger.
