  Purpose

Mallet finger is an avulsion of the extensor tendon at its insertion on the base of the distal phalanx, with or without fracture.

Treatment af mallet finger fractures involving more than 1/3 of the articulating surface is controversial. There are to our knowledge no randomized controlled trials comparing splinting and surgical treatment with extension block technique.

The aim of this study is to compare splinting and surgical extension block fixation of mallet finger fractures in a randomized controlled trial.Our hypothesis is that conservative treatment with splinting is comparable to surgical treatment concerning functional outcome, and may even reduce the complication rates.

Primary Outcome Measures:
  • Extension deficit [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Extension deficit measured in degrees, using goniometry.


Secondary Outcome Measures:
  • Range of motion (ROM) [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    (ROM)measured in the injured joint, using goniometry. Degrees.

  • Pain [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Pain in the affected join, using the VAS-scale.

  • Bump [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Presence of bump on the fracture-site. Objective examination.

  • Complications [ Time Frame: 6 month ] [ Designated as safety issue: No ]

    Objective examination for:

    • swan neck deformity
    • skin necrosis
    • nail deformities
    • infection
    • non-union(x-ray)

  • DASH [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Questionary: Disabilities of the Arm, Shoulder and Hand Danish version

  • Crawford score [ Time Frame: 6 month ] [ Designated as safety issue: No ]
    Crawford score-scale.
