Brief summary
Mallet finger fractures are injuries affecting the tip of the finger and can be treated either with splinting or surgery. However, there is no clear agreement on which treatment provides better outcomes for certain types of these fractures. In this study, patients with mallet finger fractures were randomly assigned to receive either surgical treatment using a pin-orthosis extension-block pinning technique or conservative treatment with splint immobilization. Patients were followed at regular intervals, and outcomes such as finger movement, function, bone healing, and complications were evaluated over time. The purpose of this study is to compare these two treatment approaches and determine which one leads to better clinical and functional outcomes.
Detailed description
Mallet finger fractures, particularly those involving a significant portion of the distal interphalangeal joint articular surface, present a therapeutic challenge, and there is no consensus regarding the optimal treatment strategy. Both conservative management with splinting and various surgical techniques have been described in the literature. This randomized controlled trial was designed to compare the clinical and radiographic outcomes of the pin-orthosis extension-block pinning technique and conventional conservative treatment in patients with mallet finger fractures. Patients were randomly assigned to either surgical or conservative treatment groups and followed at regular intervals. Clinical and functional outcomes were assessed throughout the follow-up period to evaluate the effectiveness and safety of both treatment approaches."
Interventions
The pin-orthosis extension-block pinning technique was performed under appropriate anesthesia. A Kirschner wire was used to block extension at the distal interphalangeal joint and stabilize the fracture fragment, followed by immobilization with an orthosis. The fixation was maintained for a defined period, and patients were followed according to the study protocol.
Conservative treatment consisted of continuous splint immobilization of the distal interphalangeal joint in extension. Patients were instructed to maintain uninterrupted splint use for the recommended duration with regular follow-up visits to monitor compliance and clinical progress.

Intervention model description
Participants were randomly assigned to one of two parallel groups: surgical treatment using the pin-orthosis extension-block pinning technique or conservative treatment with splinting. Each participant remained in the assigned group throughout the study
