Metacarpal shaft fracture fixation with intramedullary k-wire: Surgical and Clinical outcomes

Abstract

Background: Metacarpal fractures are among the most common fractures. The majority of metacarpal shaft fractures can be treated conservatively. There are numerous indications for operative treatment and various fixation techniques. The purpose of this prospective study was to assess the surgical and clinical outcomes of metacarpal shaft fractures using intramedullary fixation by K-wire (Kirschner wire). Materials and Methods: 15 cases of Metacarpal shaft fractures underwent surgery with Intra medullary fixation by K-wire. The study was conducted from March 2015 to February 2016 admitted to Navodaya Medical College and research center, Raichur. We evaluated the DASH score to determine the outcomes. Results: All fractures got united in our study and all patients were available for follow up. Two superficial wound (pin site) infections noted which healed with intravenous antibiotic treatment and regular pin site dressing. There were no major complications noted. All patients regained full flexion at the MCP and IP joints but two patients had a mild extensor lag of about 10°. At final follow up the mean DASH score in our study was 4.3 (range: 0-7.2). Conclusion: Closed or minimally invasive fixation with Kirschner wire (k-wire) is a safe method and can be performed with minimal complications. It can be seen as good choice in selective metacarpal shaft fractures.
