Trigger digits and de Quervain's disease are the 2 most common forms of tenosynovitis tendinopathy.
Diagnosis is usually clinical.
If required, the single most useful and accurate investigation is a high-resolution ultrasound scan.
Treatment may involve non-steroidal anti-inflammatory drugs (NSAIDs), splinting, corticosteroid/local anaesthetic injections, or surgery.
Tenosynovitis of the hand and wrist is a group of entities with a common pathology involving the extrinsic tendons of the hand and wrist and their corresponding retinacular sheaths. They usually start as tendon irritation manifesting as pain, and can progress into catching and locking when tendon gliding fails.
History and exam
- presence of risk factors
- location over and around a retinacular sheath
- pain increased with motion
- response to anaesthetic injection
- painful popping sensation with finger flexion and extension (trigger finger)
- palpable nodule at the level of the metacarpal head (trigger finger)
- pain, tenderness, and swelling localised to radial side of wrist (de Quervain's disease)
- pain and swelling proximal to wrist joint (intersection syndrome)
- pain, swelling, tenderness at Lister's tubercle (extensor pollicis longus tenosynovitis)
- ulnar-sided wrist pain (extensor carpi ulnaris tenosynovitis)
- pain at palmar wrist crease over scaphoid tubercle and along length of tendon (flexor carpi radialis tenosynovitis)
