Is ulnar styloid bursitis the same as tenosynovitis?
Ulnar styloid process inflammation is not tenosynovitis. The two conditions have different causes, as detailed below:
Ulnar styloid process inflammation results from overuse of the wrist, causing aseptic inflammation due to repeated stretching and pulling in certain areas. It typically does not present obvious redness, swelling, heat, or pain, but there is significant tenderness, and pain worsens during wrist joint movement. Tenosynovitis, on the other hand, also arises from aseptic inflammation at sites subjected to repeated flexion, extension, and traction, and usually lacks noticeable redness, swelling, warmth, or pain.
For ulnar styloid process inflammation, once symptoms appear, active symptomatic treatment is necessary. First, physical activity should be reduced, and strict rest and protection of the affected area are essential, which greatly benefits symptom improvement. The area must not be exposed to cold; local hot compresses or soaking may help. Second, under a doctor's guidance, oral non-steroidal anti-inflammatory drugs (NSAIDs) can be taken to relieve pain—for example, nimesulide capsules. Topical application of blood-activating and stasis-resolving plasters, such as Huoxue Zhitong plaster, may also be used. Additionally, local corticosteroid injections—commonly using a mixture of triamcinolone acetonide and lidocaine—can provide excellent results.
