Abstract
Our preliminary study retrospectively assessed outcomes after the use of autogenous iliac bone grafts combined with internal fixation to repair refractory bone nonunions and bone defects associated with supracondylar or intracondylar humeral fractures, or both. We identified 22 patients (14 men and 8 women) with a mean age of 33.8 years (range, 17-60 years) with bone nonunion and severe bone defects associated with supracondylar or intercondylar humerus fractures, or both. The humeral condyle in each patient was anatomically reconstructed using autologous iliac bone grafts and internal fixation. Active functional exercise was initiated 3 to 4 weeks after surgery. The following variables were assessed: preoperative and postoperative elbow range of motion, Mayo Elbow Performance Score (MEPS), and postoperative complications. Mean follow-up was 38.6 months. Mean duration until bone union was 5.6 months. Preoperatively, 16 patients had a fair or poor MEPS (<75). At final follow-up MEPS was excellent (>90) in 8, good (75-90) in 9, fair (60-74) in 4, and poor (<60) in 1 patient. Postoperative heterotopic ossification anterior to the elbow joint occurred in 2 patients. Our preliminary results suggest that anatomic reconstruction of the humeral condyle using autogenous iliac bone grafting with internal fixation can improve elbow joint function in patients with bone nonunion and bone defects associated with supracondylar or intracondylar humeral fractures, or both. Larger scale studies are warranted to confirm our findings and compare the efficacy of this vs other surgical approaches.
