Stubbing of the finger-tip is a common injury in sports such as basketball, volleyball, cricket and football. This can result in a Mallet finger deformity, where the end joint of a finger cannot be actively straightened out. In most mallet finger cases seen at The Alfred, the skin remains intact, and the impairment results from a tear of the extensor tendon or an avulsion (a small fracture where the tendon attaches to the bone). Treatment commonly involves immobilising the end joint of the finger in a splint for six or more weeks so patient compliance is a major factor in the quality of the outcome achieved.

This study aims to compare two different types of splintage (the commonly used thermoplastic thimble splint and the aluminium-foam “Mexican hat” splint which is in use in Britain) with a control splint (thermoplastic prefabricated “stack splint” with tape). Outcome measures will include patient compliance with the splint, degree of extensor lag, active movement of the joint, and any complications.

The null hypothesis is that there are no differences in outcome between different methods of conservative splinting treatment for mallet finger.

Condition Intervention
Mallet Finger Device: Circumferential thermoplastic thimble splint Device: dorsal aluminium foam "Mexican Hat" splint Device: stack splint (control)

Study Type: Interventional

Primary Purpose: Treatment
Official Title: Comparison of Splinting Interventions for Minimising Extensor Lag in Mallet Finger Injuries

Further study details as provided by Bayside Health:

Primary Outcome Measures:
  • Degree of extensor lag at distal inter-phalangeal (DIP)joint

Secondary Outcome Measures:
  • Active range of motion at DIP
  • Patient compliance with splinting regime, based on self-report (as described above)
  • Patient satisfaction with result on 5-point likert scale
  • Complications
  • Pain, measured by 10 point Visual Analogue Scale
