Intervention 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.
Primary purpose: TREATMENT

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.

Eligibility criteria: Inclusion Criteria:

* Wehbe Schneider type 1 - 2 and type A - B fractures
* ability to provide closed reduction
* patients' voluntariness

Exclusion Criteria:

* Wehbe Schneider type C and type 3 fractures

Primary outcomes:
measure: Extension deficit
timeFrame: 12 months
measure: DIP flexion
timeFrame: 12 months
measure: Days to return to work
timeFrame: Starting from the date of the start of treatment until patients returns to work, assessed up to 12 months
Secondary outcomes:
