Mallet Finger
Conditions
Brief summary
A randomized clinical trial, with patients treated either by a custom thermoplastic orthosis or by the Kirschner wire with the distal interphalangeal (DIP) joint extended. Evaluating the treatment efficacy of the operation management compared with a conventional orthosis.
Interventions
PROCEDUREcustom thermoplastic orthosis
extended the DIP by a custom thermoplastic orthosis or the Kirschner wire through the joint

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Range of motion(ROM) of the DIP joint from the first week up to the 16th week after the treatment completed | The first visit(Enrolled and completed treatment), 8 weeks after first visit(two weeks after 6 weeks fixation), 16 weeks(4 weeks after six weeks Rehabilitation) | Use a Protractor to measure the maximum degree of active flexion of the DIP joint at the first visit and at the end treatment; Use a Protractor to measure the maximum degree of active extension of the DIP joint at the start of immobilization and end of treatment. (If the maximum degree of active flexion of two time periods are 40° and 40°，respectively; the maximum degree of active extension of two time periods are 20° and -10°，respectively. We could get the range of motion of the DIP joint of two time periods are 20°\ 40° and -10°\ 40°，respectively. The maximum extension angle increased by 30 degrees).To assess whether there was a statistical difference in ROM changes between the two groups before and after treatment. |
