Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
patient and therapist will be unaware of the next treatment (or control) group to be assigned at the time of recruitment to the trial. Allocation will be concealed by using sealed opaque envelopes with the treatment type unknown to the therapist and unable to be changed.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computer generated randomised sequence
Masking / blinding
Blinded (masking used)

Summary
Brief summary
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.
