Abstract
BACKGROUND

Leiomyosacromas in the Extremities are rare malignant smooth muscle tumors. Adjuvant radiation therapy, in combination with wide surgical excision allows the best chance of treatment. During the follow up pathological fractures are common complications that can be accompanied by Implant failure and defect situations that are most challenging in their management.

CASE SUMMARY

We present a case of a 52-year-old female suffering from a pathological fracture of the humeral shaft 10 yr after resection of a Leiomyosarcoma and postoperative radiotherapy. She developed implant failure after retrograde nailing and another failure after revision to double plate fixation. In a two-stage revision, the implants were removed and the huge segmental defect created after debridement was bridged by a compound osteosynthesis with nancy nails and bone cement for formation of the induced membrane. Due to the previous radiotherapy treatment, 20 cm of the humeral shaft were declared devascularized but were left in situ as a scaffold. In the second stage, a vascularized fibula graft was used in combination with a double plate fixation and autologous spongiosa grafts for final reconstruction.

CONCLUSION

This combinatory treatment approach led to a successful clinical outcome and can be considered in similar challenging cases.

Core tip: We present an innovative treatment alternative for segmental bone defects after pathological fracture, tumor resection and radiation of the humerus. A combination of Induced membrane, vascularized fibula graft and double plate fixation was used to bridge a segmental bone defect. Devascularized bone stock was left in situ as a scaffold and not resected as usual. The treatment approach led to a successful clinical outcome and can be considered in similar complex cases.
