Total Scapular Prosthesis, an Option for the Treatment of Scapular Chondrosarcoma.

ABSTRACT

Introduction: Chondrosarcoma has the highest prevalence among the primary malignant bone tumors in adults over the age of 50, and the scapular region is the most affected anatomical site. Case Report We report the case of a 66-year-old female patient, with no previous medical history, who consulted for aggravating mixed, non-specific, and atraumatic pain in the right shoulder, evolving for a year. The radiological assessment, including a computed tomography (CT) scan, a magnetic resonance imaging, and a tumor CT-guided biopsy, confirmed the diagnosis of a Grade 2 chondrosarcoma. A curative surgical treatment was performed, by an extended tumor resection and simultaneous joint reconstruction by a reversed total shoulder prosthesis with a custom-made total scapular prosthesis. This option allows to maintain survival prognosis, associated with the preservation of upper limb function. Conclusion: The results were conclusive at the curative level and very encouraging from the functional point of view with progressive and partial recovery of the articular amplitudes, allowing the preservation of patient's autonomy and quality of life. No complications such as scapular dislocation or tumor recurrence were documented at 3-year postoperative follow-up.
