Comparison of New Suture Anchor Technique for Bony Mallet Injury Versus Conservative Treatment

Study Overview
=================
Brief Summary
-----------------
This study aims to compare conservative treatment versus a new suture anchor technique for bony mallet finger in 29 patients.

Detailed Description
-----------------
This study aims to compare conservative treatment versus a new suture anchor technique for bony mallet finger in 29 patients who presented to investigators' clinic between 2013 and 2015. Patients were randomly assigned to conservative or surgical treatment groups. Patients in the conservative group were followed with immobilization with aluminum splint and physical therapy. Patients in the surgical group were treated with investigators' new surgical suture anchor technique and then received physical therapy. The patients were followed for 12 months. Primary study outcomes were extension deficit, days to return to work and DIP flexion.

Design Details

Primary Purpose: Treatment
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: Patients were randomly assigned to surgical or conservative groups. After 6 weeks patients in both groups were started on the same rehabilitation protocol.
Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Conservative Treatment<br>Patients were treated with 6 weeks with splinting and were then started on physical therapy for 2 weeks. | Procedure: Conservative Treatment<br>* The injured finger was immobilized in an aluminium splint for 6 weeks. Patients were then started on physical therapy for 2 weeks.<br>|
| Active Comparator: Surgical Treatment<br>Patients were treated with the new suture anchor technique and after 6 weeks were started on physical therapy for 2 weeks. | Procedure: Suture anchor technique<br>* Suture anchors were used to attach bony fragment. On week 6, patients were then started on physical therapy for 2 weeks.<br>|
