Clavicula Pro Humero Reconstruction for Malignant Tumor of the Proximal Humerus in Children and Adults

Abstract

Background/aim: The effectiveness of clavicula pro humero (CPH) reconstruction for pediatric proximal humerus sarcoma has been reported in a small number of cases. We aimed to investigate the effectiveness of biological CPH reconstruction for malignant bone tumors of the proximal humerus in children and adults.

Patients and methods: This was a retrospective cohort study that included eight patients who underwent CPH reconstruction due to a malignant bone tumor around the proximal humerus. Postoperative parameters, including complications, postoperative upper limb function, and the period until bone fusion, were investigated.

Results: Three patients had non-union and fracture of the clavicular segment. Among them, one patient underwent revision surgery for internal fixation and bone grafting. Five patients achieved bone fusion, and the overall mean Musculoskeletal Tumor Society score was 70%, which is comparable to previous reports.

Conclusion: CPH reconstruction is an effective technique for malignant bone tumors of the proximal humerus in all ages.
