De Quervain tendovaginitis

What is De Quervain tendovaginitis?

De Quervain tendovaginitis is an inflammatory or inflammatory-like irritation of the tendon sheaths of the thumb extensor and abductor tendons in the first extensor tendon compartment at the radial styloid process. Thickened tendon glide tissue and a narrow tendon compartment lead to friction, pain and loss of function.

Synonyms: de Quervain tendovaginitis, radial styloiditis. ICD-10: M65.4.

• Often with repetitive stress (e.g. carrying babies, gardening, crafts, intensive smartphone use)
• Typical patient groups: new parents, craftsmen, musicians, athletes, people with desk work

Anatomy: The first extensor tendon compartment

On the thumb side of the wrist, two important tendons run in a common channel (first extensor tendon compartment): the tendon of the abductor pollicis longus (APL) and that of the extensor pollicis brevis (EPB). They are covered by the extensor retinaculum, which guides the tendons closely to the bone.

• APL: leads the abduction of the thumb
• EPB: stretches the metatarsophalangeal joint of the thumb
• Tendon sheath: reduces friction and enables gliding movement
• Anatomical variant: Separation wall (septum) between APL and EPB - important for therapy planning

If there is swelling of the tendon sheath or thickening of the retinaculum, a bottleneck occurs. This leads to pain when moving the thumb and grasping objects.

Typical symptoms

• Stabbing or pulling pain on the thumb side of the wrist (radial)
• Increased pain when grasping, spreading, lifting or turning (e.g. opening bottles, picking up a child)
• Tenderness over the radial styloid process
• Sometimes palpable thickening or rubbing/crunching (crepitus)
• Loss of strength in the grip, unsteady holding
• Occasionally radiating pain into the forearm

A positive Finkelstein or Eichhoff test is characteristic: When the thumb is folded into the hand and the hand is bent towards the little finger side, the pain appears clearly over the first extensor tendon compartment.

Causes and risk factors

The disease usually arises from overload and repeated microtraumas. Acute injuries are less common. Hormonal factors (e.g. postpartum, breastfeeding) and comorbidities can make the tendons and tendon gliding tissue more sensitive.

• Repetitive tasks: frequent lifting, carrying, screwing, typing/swiping on the smartphone
• Sports and hobbies that involve thumb and wrist strain (e.g. climbing, rowing, tennis, musical instruments)
• Postpartum/breastfeeding: frequent carrying of the baby, hormonal changes
• Concomitant diseases: Rheumatoid arthritis, diabetes, thyroid dysfunction
• Occupational stress and lack of regeneration time
• Anatomical constrictions or a separate EPB tendon compartment

Diagnostics: This is how we make the diagnosis

The diagnosis is primarily clinical. A careful history and examination are crucial to rule out differential diagnoses and plan appropriate treatment.

• Inspection and palpation: tenderness over the first extensor tendon compartment
• Provocation tests: Finkelstein/Eichhoff test, WHAT test (Wrist Hyperflexion and Abduction of the Thumb)
• Functional test: thumb mobility, grip strength

Imaging is used specifically:

• Ultrasound: shows thickened tendon sheath, effusion, gliding disorders, septa; also serves to control injection
• X-ray: to rule out bony causes (e.g. rhizarthrosis, old fractures)
• MRI: rarely necessary, if the course or operation planning is unclear

Differential diagnoses include: the intersection syndrome (painful area further towards the forearm), rhizarthrosis (thumb saddle joint arthrosis), ganglion, irritation of the superficial branch of the radial nerve (Wartenberg syndrome) as well as ligament and tendon lesions.

Conservative therapy: gentle and structured

The aim is to calm the irritation, improve lubrication and restore resilient function. In most cases, conservative treatment is successful.

In the postpartum phase and breastfeeding period, we initially prefer gentle measures (splint, ergonomics, physiotherapy). Therapy steps are individually tailored.

Injection therapy: targeted anti-inflammatory action

If symptoms persist despite consistent protection and therapy, an ultrasound-guided injection into the first extensor tendon compartment can be considered. A low-dose corticosteroid is usually used in combination with a local anesthetic.

• Advantages: often rapid relief, can avoid surgery
• Technique: ultrasound-assisted, precise deposition into the affected compartment(s), if necessary, consideration of an EPB septum
• Risks: temporary pain, skin lightening/tissue atrophy, rarely tendon weakening or rupture, infection (very rare)

During pregnancy/breastfeeding only after carefully weighing the benefits and risks. We make the decision together with you based on your individual situation.

Regenerative processes: only selective

The evidence is currently limited for autologous blood/PRP injections or hyaluronic acid in De Quervain tendovaginitis. In selected cases with a chronic course, this can be discussed as an additional option, always after explanation of the benefits and uncertainties. Conservative therapy with, if necessary, corticosteroid injection remains standard.

Operation: Relief of the first extensor tendon compartment

Surgical decompression should be considered if symptoms persist for weeks to months despite consistent conservative therapy (including, if necessary, injection) or if there is a clear early bottleneck situation with loss of function.

• Procedure: Splitting the retinaculum over the first extensor tendon compartment, if necessary opening a separate EPB sub-compartment
• Goal: Enlarge the sliding channel, restore painless sliding
• Care: Protect the sensitive superficial radial nerve, opening preferably dorsally to avoid subluxation of the tendon on the volar side

Follow-up treatment: short-term protection, early functional movement exercises, wound control. Light activities often after 1-2 weeks, heavier activities after individual approval. Scar care and targeted exercise programs support recovery.

As with any procedure, there are risks (e.g. impaired wound healing, nerve irritation, persistent sensitivity of the scar, rarely persistent symptoms). We discuss the procedure and alternatives in detail in advance.

Course and prognosis

Many affected people benefit from consistent relief, splints and targeted therapy within just a few weeks. For long-standing or severe cases, recovery can take several weeks to a few months. Relapses are possible, especially if the load remains unchanged.

• Early intervention often improves the chances of recovery
• Ability to work: dependent on activity and handedness; Adjustments in the workplace are helpful
• Sport: gradual return to work, initially pain-adapted exercises, later increasing the load

Self-help and exercises

Exercises should be performed with little pain. Increasing discomfort, numbness or significant swelling are a signal for adjustment and medical consultation.

Differential diagnoses at a glance

• Intersection syndrome: painful area 4–6 cm towards the forearm, often with a rubbing noise
• Rhizarthrosis (thumb saddle joint osteoarthritis): pain in the ball of the thumb, positive grind test
• Ganglion on the wrist: palpable bulging cyst
• Wartenberg syndrome: Irritation of the sensitive radial branch with burning sensations
• Tendon or ligament injuries (e.g. SL ligament injury), fractures, tendon ruptures
• TFCC lesions: more ulnar (little finger side) wrist pain

The distinction is important because therapy and prognosis vary. If necessary, we will clarify this with ultrasound and further tests.

Prevention and workplace tips

• Dose stress, plan breaks, vary tasks
• Use ergonomic aids: wrist rest, vertical mouse, larger grip diameter
• Correct lifting and carrying technique: palms up, do not overextend your thumbs
• Warm up before sports/activities, regular mobilization
• React early when symptoms first appear – don’t “work through” them

When should you see a doctor?

• Increasing pain despite relief for more than 2-3 weeks
• Pain at night when resting, significant swelling or redness
• Numbness, tingling or loss of strength
• After trauma with persistent pain
• Fever, general feeling of illness (suspected infection)

An early diagnosis helps to have a positive influence on the course and avoid complications.
