Vascularized fibular epiphyseal transfer. A clinical study
Clinical Orthopaedics and Related Research
|September 1, 1986
Summary
Free vascularized fibular epiphyseal transfer shows potential for bone growth in children with congenital abnormalities or growth arrest. However, premature closure of the epiphysis can limit growth, requiring further investigation.
Area of Science:
- Orthopedic surgery
- Regenerative medicine
- Pediatric bone health
Background:
- Nonvascularized and vascularized epiphyseal transfer are surgical techniques used to address bone growth issues.
- Epiphyseal transfer aims to restore or enhance longitudinal bone growth, particularly in pediatric cases.
Observation:
- A review of eight patients undergoing free vascularized fibular epiphyseal transfer was conducted.
- The study examined the potential for growth following bone transfer with an open epiphysis.
Findings:
- Transferring bone with an open epiphysis demonstrated potential for growth in cases of congenital abnormalities or epiphyseal arrest due to trauma/infection.
- In four patients, premature epiphyseal closure halted growth; in the other four, open epiphyses allowed continued growth of the transferred bone.
- The procedure, while experimental, involves combined epiphyseal and metaphyseal vessel transfer monitored by a skin island for viability.
Implications:
- Free vascularized fibular epiphyseal transfer may offer a viable option for managing specific pediatric bone growth disorders.
- Further research is warranted to optimize this technique and improve outcomes, especially concerning the prevention of premature epiphyseal closure.
- The use of a skin island as a viability monitor highlights the importance of vascular supply in successful epiphyseal transfer.
