First Dorsal Compartment Injection
Other Names
- First Dorsal Compartment Injection
- Abductor Pollicis Longus and Extensor Pollicis Brevis Injection
- De Quervain Injection
- De Quervain's Injection
Background

Key Points
- Needle: Use a 25 gauge, 1-1.5 inch needle
- Transducer: high frequency, linear
- Note: about 1/3 of EPB tendons are separated from the APL tendon by a septa
- Preferred technique: Short axis, in plane
Anatomy of the First Dorsal Compartment
- Located lateral to the radial styloid process
- Contains: extensor pollicis brevis (EPB) abductor pollicis longus (APL) tendons
- In about 1/3 of patients, the EPB tendon is compartmentalized off from the APL tendon[2]
Palpation Guidance vs Ultrasound Guidance
- Success rate of unguided injections ranges from 58% to 93% accross multiple studies[3][4][5]
- Ultrasound guided success rate has been reported at 93.75%[6]
- Ultrasound allows visualization of any septum in first dorsal compartment, identify each individual tendon and exact area of tenosynovitis
- Sawaizumi et al: Complications of palpation guided injections is estimated at 36%[7]
- Includes: atrophy of subcutaneous fat tissue and/or depigmentation around the needle insertion site
- Jeyapalan et al: no complications when performed under US guidance[6]
Indications
Contraindications
- Absolute
- Anaphylaxis to injectates
- Overlying cellulitis, skin lesion or systemic infection
- Relative
- Can be treated with less invasive means
- Hyperglycemia or poorly controlled diabetes
- Lack of symptom improvement with previous injection
Procedure





Equipment
- Sterile including chloraprep, chlorhexadine, iodine
- Gloves
- Needle: typically 21-25 gauge, 1.5 inch
- Syringe: 5-10 mL
- Gauze
- Ethyl Chloride
- Bandage
- Injectate
- Local anesthetic
- Corticosteroid
- Sterile probe cover
Ultrasound Findings
- Best visualized in short axis using high frequency, linear transducer
- Common ultrasound findings include:
- Anechoic fluid surrounding the tendon
- Tendon thickening
- Intrasubstance tears
- Normal variations
- Multilamellar APL tendon (looks like a split or tear)
- Septum between APL or EPB[10]
Technique: Short Axis, In Plane
- Patient position
- Seated with arm resting on a neutral surface for the proceduralist
- Ulnar aspect is down, thumb and radial wrist are pointed up
- Transducer position
- Short axis to the first extensor compartment
- Needle Approach/ Orientation
- In plane
- Lateral to medial
- Target
- Tendon sheath of APL, EPB
- Pearls and Pitfalls
- Identifying location of tenosynivitis may increase precision
- Do not confuse multilamellar APL tendon with a tear
- Observe the injectate as it courses through the tendon sheath(s)
- Avoid the radial artery
Technique: Short Axis, Out of Plane
- Patient position
- Seated with arm resting on a neutral surface for the proceduralist
- Ulnar aspect is down, thumb and radial wrist are pointed up
- Transducer position
- Short axis to the first extensor compartment
- Needle Approach/ Orientation
- Out of plane
- Proximal to distal or distal to proximal
- Target
- Tendon sheath of APL, EPB
- Pearls and Pitfalls
- See above
Aftercare
- No significant restrictions
- Can augment with ice, NSAIDS
- Consider placement in a Thumb Spica Splint
Complications
- Skin: Subcutaneus fat atrophy, skin atrophy, skin depigmentation
- Painful local reaction
- Infection
- Hyperglycmia
- Tendon, nerve or blood vessel injury
