Surgical management of a long segmental defect of the humerus using a cylindrical titanium mesh cage and plates: a case report.

This is a case report of a patient who sustained multiple gunshots resulting in a Gustilo Anderson type IIIB mid-shaft humeral fracture associated with extensive segmental bone and soft-tissue loss. The patient was treated initially by multiple irrigations, wound debridement, and a unilateral external fixator. After the soft tissue healed without infection, the mid-shaft humeral defect of approximately 8 cm segmental bone loss was reconstructed with a cylindrical titanium mesh cage packed with a composite of cancellous allograft and demineralized bone matrix putty and stabilized with limited contact dynamic compression plates. At 13 months follow-up, plain radiographs demonstrated a healed construct with good alignment, and computed tomography images demonstrated bony in-growth through the cage. The patient had full range of motion at the shoulder and the elbow. This technique may be a reasonable alternative when treating large segmental bone defects of the humerus.
