Simultaneous Bilateral Scapular Fractures: A Scoping Review

Background and Objectives: Simultaneous bilateral scapular fractures are exceptionally rare injuries and are most commonly associated with high-energy trauma, convulsions, or electrical injury. Their occurrence following low-energy trauma is extremely uncommon. This study aimed to conduct a scoping review of the literature on simultaneous bilateral scapular fractures, with emphasis on demographic characteristics, mechanisms of injury, fracture patterns, treatment strategies, and clinical outcomes. To provide clinical context, the findings are illustrated by a case of a 43-year-old previously healthy recreational athlete who sustained simultaneous bilateral scapular fractures after a low-energy fall directly onto the back. Materials and Methods: A scoping review of the literature was conducted in accordance with PRISMA-ScR guidelines using the PubMed/MEDLINE and Scopus databases. Studies reporting simultaneous bilateral scapular fractures were identified and analyzed with respect to demographic characteristics, mechanisms of injury, fracture patterns, treatment modalities, and outcomes. Results: Thirty-seven studies published between 1946 and 2025 were included, comprising a total of 43 patients. Most cases resulted from high-energy trauma (41.9%), convulsions (25.6%), or electrical injury (16.3%). Low-energy trauma and spontaneous fractures were rare. The scapular body was the most commonly involved anatomical region. Conservative treatment predominated and was generally associated with favorable functional outcomes, while surgical intervention was reserved for displaced or intra-articular fractures. The illustrative case involved bilateral comminuted extra-articular fractures of the scapular bodies and spines without associated injuries and was managed conservatively, resulting in complete fracture healing and full, painless shoulder range of motion. Conclusions: The findings of this scoping review, illustrated by the representative clinical case, indicate that simultaneous bilateral scapular fractures may occur even after low-energy trauma in otherwise healthy individuals. Bilaterality alone should not be interpreted as an independent indication for surgical treatment when fractures are stable and minimally displaced. A high index of clinical suspicion and appropriate radiological evaluation are therefore warranted, particularly in emergency and trauma settings, in order to avoid missed or delayed diagnosis, even in cases with seemingly benign mechanisms of injury.
