About this study

This study aims to compare two different methods of corticosteroid injections in patients with triggerfinger, and to study the effects of these injections by day-to-day self-assessment by the included study persons for four weeks. The patient assess: 1. Pain 2. Motion and 3. Triggering by VAS scale every day for four weeks.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

•

  • Triggering of one or more fingers and/or impaired active finger motion and/or pain during active finger motion
  • Localized tenderness volar to the MCP joint of the affected finger
  • The patient seeks treatment

Exclusion criteria

  • Previous treatment for triggerfinger in the finger to be treated
  • Impaired function of finger due to previous trauma/infection or other condition
  • Suspicion of other cause than triggeriinger/tendovaginitis
  • Patient not able to follow instructions

Treatment and study plan

Proximal phalangeal level

Procedure

Injection of methyl prednisone and lidocaine in the tendon sheet at the level of the proximal phalanx

Volar to the MCP-joint

Drug

Injection of methyl prednisone and lidocaine in the tendon sheet volar to the MCP-joint

Primary outcomes

  1. Pain after injection

    Time frame: Four weeks

    Visual analouge scale (VAS), range 0-10, where 0 indicates "no pain" and 10 "maximum pain"

  2. Impairment of finger motion

    Time frame: Four weeks

    Visual analouge scale (VAS), range 0-10, where 0 indicates "no impairment" and 10 "maximum impairment"

  3. Triggering

    Time frame: Four weeks

    Visual analouge scale (VAS), range 0-10, where 0 indicates "no trigger phenomenon" and 10 "Trigger phenomenon all the time/ locked finger"

Secondary outcomes

  1. Quick-DASH
