Wrist Sprain

Upper Limb

Overview

Wrist sprains involve acute ligamentous injury to the wrist complex, commonly affecting the scapholunate, lunotriquetral, or radiocarpal ligaments. These injuries typically result from forced hyperextension, hyperflexion, or radial/ulnar deviation mechanisms. Severity ranges from Grade I (mild ligamentous stretching) to Grade III (complete ligamentous rupture).

Pathophysiology

Ligamentous structures around the wrist are stretched or torn when the joint is forced beyond its normal range of motion. This causes disruption of collagen fiber alignment, inflammatory cascade activation, and microvascular bleeding within the ligamentous tissue. The injury compromises proprioceptive feedback and joint stability, leading to inflammation, swelling, and pain. Grade I involves microscopic tearing without functional instability; Grade II involves partial tearing with some functional compromise; Grade III represents complete rupture with significant instability and potential for chronic pain or instability if not properly managed.

Typical Presentation

Site

Dorsal or volar wrist, often localized to the radiocarpal joint, scapholunate joint, or lunotriquetral articulation; may involve multiple ligamentous structures

Quality

Sharp, aching, or throbbing pain; may be accompanied by clicking or clunking sensations indicating ligamentous laxity

Intensity

Grade I: mild to moderate (3-5/10); Grade II: moderate to severe (5-7/10); Grade III: severe with functional limitation (7-10/10)

Aggravating

Gripping activities, forced wrist extension or flexion, radial/ulnar deviation movements, weight-bearing through the hand, twisting motions, sports involving ball handling

Relieving

Rest and immobilization, ice application, elevation, non-steroidal anti-inflammatory medications, gentle passive motion within pain-free range

Associated

Swelling (may be diffuse or localized), bruising, reduced grip strength, warmth over injury site, reduced wrist range of motion, difficulty with fine motor tasks, apprehension with certain movements, possible feeling of instability or 'clunking'

Orthopaedic Tests

Scaphoid Compression Test (Axial Loading)

Procedure

Patient's wrist is placed in neutral or slight extension. The examiner applies axial compression through the thumb or along the long axis of the radius while palpating the scaphoid tubercle for tenderness or pain reproduction.

Positive Finding

Localized pain or tenderness over the scaphoid tubercle with axial loading

Sensitivity / Specificity

72% / 65%

Eiff et al., 2011, American Family Physician

Interpretation

Suggests possible scaphoid fracture or scaphoid ligamentous injury; requires imaging correlation given moderate diagnostic accuracy

Wrist Flexion-Extension Range of Motion Assessment

Procedure

Patient actively moves wrist through full flexion and extension. Examiner measures total range using goniometer (or visual estimation) and notes pain reproduction or limitation.

Positive Finding

Reduced range of motion (typically <60° in one or both directions) or pain at end-range, compared to contralateral side

Sensitivity / Specificity

Unknown / Unknown

Interpretation

Documents functional impairment and severity of sprain; helps monitor recovery; specific diagnosis requires correlation with clinical history and imaging

Radial and Ulnar Deviation Range of Motion

Procedure

Patient actively performs radial (thumb-side) and ulnar (pinky-side) deviation of the wrist. Examiner measures movement with goniometer and notes pain or limitation.

Positive Finding

Reduced total deviation (<40° radial + ulnar combined) or asymmetry compared to contralateral wrist, particularly with pain

Sensitivity / Specificity

Unknown / Unknown

Interpretation

Indicates ligamentous or capsular involvement affecting medial-lateral stability; reflects functional loss from moderate to severe sprains

Wrist Ligament Stress Test (Radial and Ulnar Collateral Ligament)

Procedure

With wrist in neutral or slight flexion, examiner applies radial (thumb-side) or ulnar (pinky-side) deviation stress while stabilizing the forearm, palpating for ligament laxity or guarding.

Positive Finding

Pain reproduction, increased laxity, or apprehension in the direction of stress compared to contralateral side

Sensitivity / Specificity

Unknown / Unknown

Interpretation

Suggests collateral ligament injury (grade 1–2 or higher); guides conservative vs. possible surgical management decisions

Grip Strength Testing (Dynamometry)

Procedure

Patient seated with shoulder abducted 90°, elbow flexed 90°, and forearm neutral. Patient squeezes calibrated grip dynamometer with maximum effort; three trials recorded per hand.

Positive Finding

Grip strength reduced by >10–15% on the affected side, or pain reproduction during testing

Sensitivity / Specificity

Unknown / Unknown

Interpretation

Objective measure of functional limitation and pain inhibition; useful for documenting severity and monitoring rehabilitation progress; does not diagnose specific ligament injury

Scaphoid Shift Test (Watson's Test)

Procedure

Examiner's thumb presses the scaphoid tubercle palmarly while passively moving the wrist from ulnar deviation and extension to radial deviation and flexion. Patient is seated with forearm supported.

Positive Finding

Sudden 'click' or 'clunk' as the scaphoid subluxates and reduces, or apprehension/pain with this maneuver

Sensitivity / Specificity

56–73% / 60–87%

Eiff et al., 2011, American Family Physician; Reiman et al., 2013, Musculoskeletal Science and Practice

Interpretation

Suggests scaphoid ligamentous laxity or chronic scapholunate instability; useful screening test but moderate diagnostic accuracy; MRI or arthroscopy recommended for confirmation

⚠ Red Flags

  • •Severe swelling with signs of compartment syndrome (pain disproportionate to injury, pain with passive finger extension, paresthesias)
  • •Signs of neurovascular compromise (absent distal pulses, severe pallor, cold hand, progressive paresthesias)
  • •Open wound or penetrating injury suggesting possible foreign body
  • •Severe deformity suggesting possible associated fracture (particularly scaphoid fracture)
  • •Loss of conscious control or severe neurological symptoms
  • •Signs of infection (spreading erythema, warmth, systemic fever)
  • •Wrist instability with clinical evidence of midcarpal instability (positive scapholunate dissociation test)

⚡ Yellow Flags

  • •Litigation or compensation claim related to injury
  • •Significant fear-avoidance behavior disproportionate to clinical findings
  • •High pain catastrophization scores
  • •Previous chronic pain history or central sensitization features
  • •Psychological distress or mood disorder affecting rehabilitation adherence
  • •Poor social support for recovery
  • •Occupational demands incompatible with recovery timeline

Osteopathic Techniques

Region

Wrist and radiocarpal joint

Technique

Soft Tissue

Rationale

Reduces muscular guarding and promotes local circulation to facilitate healing; addresses hypertonic flexor and extensor muscles that develop secondary to ligamentous injury and protective muscle splinting

Region

Wrist articulations (radiocarpal, midcarpal, intercarpal)

Technique

Articulation

Rationale

Gentle oscillatory movements maintain joint mobility and proprioceptive feedback without stressing healing ligaments; prevents stiffness and promotes synovial fluid nutrition to articular cartilage

Region

Forearm, wrist flexors and extensors

Technique

MET

Rationale

Muscle energy techniques normalize muscle tone and restore balanced force couples around the wrist; reduces protective muscle guarding and improves active range of motion as healing progresses

Region

Lymphatic drainage of wrist and hand

Technique

Lymphatic

Rationale

Promotes drainage of inflammatory exudate and supports the healing cascade; reduces swelling and improves tissue perfusion to accelerate resolution of acute inflammation

Region

Cervical and thoracic spine, shoulder girdle

Technique

Soft Tissue

Rationale

Addresses secondary compensatory tension patterns that develop as upper limb pain forces patients to alter movement patterns; poor postural adaptation can perpetuate wrist dysfunction

Region

Wrist and hand

Technique

Functional

Rationale

Gentle, pain-free positioning facilitates proprioceptive recovery and tissue healing without aggressive loading; supports natural healing processes through functional integration

Add-On Approaches

Chinese Medicine
