Abstract

|
Distal humeral nonunion is one of the most concerned complications in elbow trauma. When bone loss at the fracture site is carried out due to nonunion, metaphyseal bone defect occurs. Therefore positioning of anatomical locking plate becomes difficult owing to abnormal bone contour, and fixation of small nonunion fragment is challenging. We introduce a good method of anatomical locking plate fixation with autogenous inlay strut bone graft for internal fixation. This technique is to insert autogenous inlay bone into the proximal medullary canal and hole of distal bone fragment which will lead to achieve correction of the anatomical alignment, length and rotation deformity. The inlay grafting is reduced to the shaft with two crossed K-wires temporarily. Definitive fixation is performed with locking plates, and autogenous bone graft is added at the defect site.
