Gradual fibular transfer by ilizarov external fixator in post-traumatic and post-infection large tibial bone defects

INTRODUCTION

Several reconstructive procedures have been used in management of large tibial bone defects including bone graft, bone transport (distraction osteogenesis) using various external fixators, and vascularized bone graft. Each of these procedures has its limitations and complications. The study describes gradual medial fibular transfer using Ilizarov external fixators in management of patients with large tibial defect, either following infection or trauma.

PATIENTS AND METHODS

Between May 2011 and June 2013, 14 patients were prospectively included in the current study. The inclusion criteria were large tibial defect due to trauma or infection with severe soft tissue compromise, and small or poor tibial bone remnants making bone lengthening difficult. Exclusion criteria were patients with vascular or nerve injuries. The average age of the patients was 31.64 (± 6.5) years. Medial fibular transfer was done for all patients using Ilizarov at a rate of 0.5 mm twice daily. Iliac bone graft was used in all patients after the transfer.

RESULTS

The average segmental bone defect of the tibia was (13.2 ± 2.6), ranging between 8 and 18.6 cm. Union was achieved in all patients with average fixator time was 32.42 (± 4.32) weeks. Average follow-up after removal of the fixator was 40.5 (± 6.9) months.

CONCLUSION

Gradual fibular transfer by Ilizarov external fixator is a reliable technique in management of post-traumatic and post-infection large tibial bone defects with good clinical outcome, and with few complications.

Outcome of low profile mesh plate in management of comminuted displaced fracture patella

PURPOSE

To assess the clinical results of using mesh plate in management of displaced comminuted fracture patella.

PATIENTS AND METHODS

Between January 2014 and October 2015, nine patients with closed displaced comminuted fracture patella were fixed using mesh plate and 2mm mini screws.

RESULTS

All fractures united after an average of 10 weeks. At final follow-up of an average 19.6 months, average postoperative Lysholm score was 89.1±4.9, and average Postoperative Böstman scale was 27.2±3.1. No hardware related complications were recorded.

CONCLUSION

Low profile mesh plate is a good option in management of comminuted fracture patella with good clinical outcome. This new surgical technique may be particularly useful in comminuted fractures when patellectomy would otherwise be considered.
