De Quervain tenosynovitis
- Tenosynovitis of abductor pollicis longus (APL), extensor pollicis brevis (EPB)
- Groove of radial styloid
- First extensor compartment
- Middle-aged, more common in women
- Associated with rheumatoid arthritis, SLE
- Overuse of the thumb
- Classically mothers that frequently lift infants
- Or secretarial, nursing occupations
- Recently, over-texting on phones has increasingly been the culprit
- Pain along radial aspect of wrist (may radiate to thumb or extend into the forearm)
- Painful abduction of thumb
- Decreased grip strength
- Swelling at tendon sheath along radial styloid
- Positive Finkelstein, pathognomonic
- Patient grasps thumb in palm of the hand and ulnar deviates the thumb and hand
- Stretches the tendons over the radial styloid producing sharp pain
- Negative Phalen and Tinel test
- Distal finger
- Other finger/thumb
- ESR usually normal
- Consider arthrocentesis for joint effusion to evaluate for crystals, gram stain, culture
- Plain films usually nondiagnostic
- May see soft tissue swelling or radial styloid sclerosis or erosion
- Important to rule out fracture, gas formation, late osteomyelitis
- US diagnostic
- Thickened extensor retinaculum (>0.45mm) overlying radial styloid
- Thickened APL and EPB under extensor retinaculum, as contrasted with unaffected wrist
- Edema surrounding tendons within first dorsal wrist compartment
- Surrounding hyperemia on Doppler within peritendinous subcutaneous area
- Intertendinous septum (hypoechoic area between EPB and APL) increases need for operative management
- Splint thumb and wrist
- Instruct patient to remove splint briefly each day to perform range-of-motion exercises
- NSAIDs for 10-14 days
- Persistent cases may require steroid injection or surgical decompression
- First steroid injection provides permanent relief in ~50%
- Intertendinous septum presence increases likelihood of needing surgery
- Rheumatology referral for joint injections and conservative treatment
- Hand surgery outpatient referral for failed conservative management
- Radiograph-Negative Hand and Finger Injuries
