Technique for harvesting tibial cancellous bone modified for use in children
1Department of Oral & Maxillofacial Surgery, Queen Victoria Hospital, East Grinstead, UK.
Insights
Harvesting adult tibial cancellous bone offers a safe and effective alternative for pediatric alveolar cleft bone grafting. This method significantly reduces hospital stays and pain, improving children's mobility post-procedure.
Area of Science:
- Orthopedic surgery
- Pediatric reconstructive surgery
- Bone grafting techniques
Background:
- Pediatric alveolar cleft reconstruction often requires bone grafting.
- Iliac crest bone grafting is a common but associated with donor-site morbidity.
- Alternative autologous bone graft sources are needed for pediatric patients.
Purpose of the Study:
- To evaluate the safety and efficacy of modified adult tibial cancellous bone harvesting for pediatric alveolar cleft grafting.
- To compare outcomes of tibial bone grafting with traditional iliac crest bone grafting in children.
Main Methods:
- Modified technique for harvesting adult tibial cancellous bone adapted for pediatric use.
- Retrospective study of 15 children undergoing secondary alveolar cleft grafting using tibial bone.
- Radiographic and clinical assessment compared to a control group receiving iliac crest bone grafts.
Main Results:
- Significantly shorter hospital stays for tibial bone graft group (mean 1 day) versus iliac crest group (mean 3 days).
- Reduced analgesic requirements in the tibial group (1-4 days) compared to the iliac crest group (1-3 weeks).
- Improved patient mobility, with children walking on day 1 after tibial grafting versus restricted walking for 1-3 weeks in the iliac crest group.
Conclusions:
- Modified tibial cancellous bone harvesting is a safe and reliable technique for pediatric alveolar cleft reconstruction.
- Tibial bone grafting offers advantages over iliac crest grafting, including decreased morbidity and faster recovery.
- This technique enhances patient comfort and functional outcomes in pediatric bone grafting procedures.
Abstract:
We present modifications of the technique of harvesting adult tibial cancellous bone that enables its safe and reliable use in children. We studied 15 children undergoing secondary grafting of alveolar clefts radiographically and clinically and compared them with a similar group of children who had bone harvested from the iliac crest. Duration of hospital stay (mean 1, range 1-2 compared with 3, range 2-4) analgesic requirements (duration 1-4 days compared with 1-3 weeks) were all considerably less when bone was taken from the proximal tibia and mobility was considerably improved (able to walk on day 1 compared with restricted walking for 1-3 weeks.
