Tendovaginitis (tendonitis) of the hand and wrist

What is tendovaginitis?

Tendovaginitis is inflammation or irritation of the tendon sheath. This surrounds the tendon like a sliding channel and produces fluid that enables low-friction gliding. If there is overload, incorrect loading or mechanical constriction, the tendon sheath reacts with swelling and pain.

Those affected complain of pulling, stabbing pain along the course of the tendon, often intensified during gripping and twisting movements. Sometimes thickenings can be felt; the movement can appear “jerky”. Special forms are de Quervain tendovaginitis of the radial wrist, tendovaginitis stenosans (so-called snapping finger) and intersection syndrome of the forearm.

Anatomy and function of the tendon sheaths

Tendons transmit muscle strength to bones. They run through narrow tunnels and tendon sheaths on the hand that protect and guide them. The inner layer of the tendon sheath produces a fluid that promotes lubrication. If this structure is irritated or constricted, painful inflammation occurs.

• Flexor and extensor tendons pass in tendon sheaths under annular and cruciate ligaments.
• Tendon sheaths are mechanically exposed: narrow spaces, repeated flexion-extension movements.
• Small volume means: slight swelling can cause significant discomfort.

Causes and risk factors

Tendovaginitis is usually the result of repetitive, monotonous movements or unusual stress. Anatomical constrictions, hormonal factors and comorbidities can also play a role.

• Repetitive grasping, turning and writing movements (computer work, crafts, musical instruments).
• High-repetition sports (climbing, rowing, tennis).
• Mechanical tightness (compartments, annular ligaments), bony edges or tendon thickening.
• Hormonal influences, e.g. B. during pregnancy/breastfeeding (common with De-Quervain).
• Metabolism and accompanying diseases: diabetes mellitus, rheumatic diseases.
• Acute overload after unusual activity or microtrauma.

Symptoms

The symptoms vary in intensity and location depending on the affected tendon. They typically occur with movement and pressure, rarely at rest.

• Local pain along the tendon or at the tendon base.
• Swelling, tenderness, occasionally warming.
• Crepitation (“rubbing”/“crackling”) when moving.
• Restriction of movement, loss of strength, fatigue.
• When the finger snaps: snapping or blocking in the flexed/extended position.
• In De-Quervain: Radial pain at the wrist, radiating into the forearm.

Warning signs: When should you clarify urgently?

• Pain at rest, severe pain at night.
• Severe redness, overheating, fever (suspected infection).
• Rapidly increasing swelling or highly acute functional impairment.
• Neurological deficits (numbness, tingling, paralysis).
• Trauma with an audible “tear” or sudden loss of strength (suspected tendon rupture).

Differential diagnoses

Not every wrist or finger pain symptom is tendovaginitis. The following diagnoses must be differentiated:

• Ganglion or synovial cyst.
• Osteoarthritis/arthritis of small wrist joints, e.g. B. STT or thumb saddle joint.
• Ligament injuries such as SL ligament or LT ligament lesion.
• TFCC lesions (ulnar wrist pain).
• Nerve compression (e.g. carpal tunnel syndrome) with pain-associated weakness.
• Tendinitis without tendon sheath involvement or tendon attachment irritation (enthesiopathies).

Diagnosis: step by step

The diagnosis is based primarily on history and clinical examination. Imaging is used to confirm and rule out other causes.

Focus on conservative treatment

In most cases, tendovaginitis can be treated successfully without surgery. Stress control, targeted temporary immobilization and functional therapy are crucial.

• Activity adjustment: temporary reduction of triggering movements, micro-breaks, ergonomics advice.
• Splints/orthosis: temporary immobilization of affected tendon tracts (e.g. thumb splint for De-Quervain).
• Cold in the acute phase to relieve pain; Heat in the subacute phase to relax muscles.
• Anti-inflammatory painkillers as needed (e.g. NSAIDs) – weigh up individually.
• Topical therapies (gels/ointments), if necessary with occlusive application according to instructions.
• Physiotherapy/occupational therapy: sliding exercises, stretching, manual therapy, neurodynamic techniques.
• Stress management in sport: dosed re-entry scheme, technique and equipment check.
• Taping/bandages for temporary relief and proprioceptive support.

The duration of conservative therapy varies; 4–8 weeks is often useful. Consistent implementation of the measures significantly improves the chances of recovery. We create an individual therapy plan and check the progress.

Injections: possibilities and limitations

If pain persists despite consistent measures, a targeted injection into the tendon sheath can be considered. It can quickly relieve pain and reduce inflammation, but is not a routine procedure without consideration.

• Corticosteroid infiltration, preferably ultrasound-guided for precise placement and protection of the tendon.
• Combination with local anesthetic for short-term pain relief.
• Careful indication: limited number of injections, sufficient intervals.

Important information: Injections can pose risks (infection, bleeding, skin atrophy, pigment change, tendon irritation or, rarely, tendon rupture). Detailed information and aseptic technique are mandatory. Regenerative procedures such as PRP are discussed in individual cases; The evidence for tendovaginitis is heterogeneous - we will advise you transparently and individually.

Operational options – when do they make sense?

If conservative therapy has been consistently exhausted over weeks to months and a relevant limitation still exists, minimally invasive surgery can be considered. The aim is to relieve pressure on the tendon.

• De-Quervain: Division of the first extensor tendon compartment, if necessary ligament plasty for guidance.
• Tendovaginitis stenosans: splitting of the A1 annular ligament when the finger snaps.
• Intersection syndrome: debridement/splitting with therapy-resistant irritation.

Operations are usually short and often take place on an outpatient basis. As with any procedure, there are risks such as impaired wound healing, scarring, nerve irritation or persistent discomfort. The decision is made individually and without time pressure - always taking your everyday requirements into account.

Everyday life, work, prevention

Ergonomics and load management are crucial to calming discomfort and preventing relapses.

• Adjust the workplace ergonomically: wrists neutral, mouse/keyboard adjusted, wrist rest.
• Micro-breaks every 30-45 minutes: loosening up, stretching, short exercises for forearm muscles.
• Check technique in sport: grip strength, racket/climbing technique, progressive increase in load.
• Vary smartphone handling, use on both sides, relieve pressure on the thumb.
• When breastfeeding: optimize carrying and holding positions, consider using a splint.

Healing process and prognosis

The overall prognosis is favorable, especially with early diagnosis and consistent relief. Acute cases often calm down within a few weeks. Chronic courses require more patience and structured therapy.

• Acute: Improvement often occurs in 2-6 weeks with relief, splints and physio.
• Subacute/chronic: 6-12 weeks or longer, gradual increase in load.
• There is a risk of relapse if the load remains high without ergonomic adjustments.
• Sport: Return to work in a symptom-oriented manner, documented pain scales help with control.

When should you seek medical advice?

• If pain does not subside after 1-2 weeks despite protection and simple measures.
• If swelling, redness and pronounced warmth occur.
• In case of snapping or blocking phenomena of the fingers.
• If an injury is suspected or if hand function is restricted.
• If recurring complaints affect your work or sport.

• Thorough anamnesis and clinical examination, including functional and provocation tests.
• High-resolution ultrasound for dynamic assessment of the tendon and tendon sheath.

• Short-term immobilization with a splint; Wear at night, wear as needed during the day.
• Gentle gliding exercises according to instructions, respecting pain as a limit.
• Work and sports breaks, implement ergonomic adjustments.
