Tenosynovitis (inflammation) of tendons (extensor carpi radialis brevis and extensor carpi radialis longus) and synovial membranes located on the thumb side in the second dorsal compartment of the wrist.
- Pain and swelling on the thumb side about 4-6 cm up from the wrist joint on the dorsal (back) aspect of the wrist.
- Often found in activities that involve repetitive wrist extension.
- The sensation of “footprints on freshly packed snow” is the hallmark for palpating (touching) the area.
- Likely entrapment and friction of the second dorsal compartment tendons with the first compartment tendons.
- Tenosynovitis were the two sets of tendons intersect.
- Rest, activity modifications, removable wrist splint, ice and NSAID’s (ibuprofen)
- Occupational Therapy
- Corticosteroid injection
- Indicated when non-operative treatment fails.
- The extensor retinaculum covering the synovial membrane and tendons is incised (released).
