A shotgun-induced nonunion humeral fracture treated by Masquelet technique and arthrodesis: a case report

INTRODUCTION AND IMPORTANCE: The Masquelet technique remains one of the procedures with low rates of failure and infection. The use of this technique in humeral defects is still rare. CASE PRESENTATION: A 38-year-old male patient with an open humeral comminuted fracture induced by shotgun injury was referred to our hospital. The Masquelet technique was chosen as the best option with a lower risk of infection and the lower expenses at this stage due to the second time of open reduction and internal fixation and bone graft failure, low patient compliance, and the increasing size of the defect due to bone absorption. An arthrodesis procedure was performed 5 days after the second Masquelet stage as restoring the elbow joint’s range of motion was impossible. CLINICAL DISCUSSION: The Masquelet technique, is a two-step surgical procedure to manage pseudoarthroses and bone defects. Various surgical options are available for performing this procedure. There are several reasons behind the rising popularity of this technique during recent years. Some of these reasons include the reproducibility of this technique, as well as requiring less time, not being technically challenging, and having fewer neurovascular complications. CONCLUSION: This case was one of the limited examples of successful implementation of the Masquelete procedure on severe traumatic injuries of the upper limb with bone defects providing more evidence on the safety and efficacy of this technique in similar conditions.
