Reconstruction of large bone defect using autogenous fibular strut and iliac bone graft for revision total elbow arthroplasty.

The stability and longevity of the prosthesis after revision total elbow arthroplasty (TEA) are greatly influenced by the reconstruction of bone defects around the distal humerus and proximal ulna. This study evaluated the clinical and radiological results of reconstruction of a large bone defect using an autogenous fibular strut and iliac bone graft in revision TEA.This retrospective study reviewed 10 patients who underwent revision TEA with autogenous fibular strut and iliac corticocancellous bone graft between March 2007 and May 2016. Range of motion (ROM), Visual Analog Scale (VAS), and Mayo Elbow Performance Score were used to evaluate clinical outcomes at the final follow-up. Plain radiographs were reviewed for bone union and the presence of re-loosening or for the presence of peri-prosthetic fractures.At the final follow-up, the ROMs of the elbow was 102.5° (range, 90-120°) from extension to flexion, 60.0° (range, 40-80°) in pronation, and 58.5° (range, 35-80°) in supination. The mean preoperative VAS and Mayo Elbow Performance Score were 5.1 and 46.5, and theses scores were improved to 2.6 and 79.0, at the final follow-up (P < .05). Union of the grafted bone with the distal humerus was achieved at an average of 4.5 months (range, 3-6 months). Re-osteolysis recurred in 2 cases, and additional surgery for bone grafting was performed in 1 case.Autogenous fibular strut bone grafting is an effective technique when revision TEA has large bone defects around the prosthesis resulting in a relatively stable prosthesis fixation and good union rate with a satisfactory clinical outcome after TEA revision.
