Abstract
Background
A peculiarity of non-vascularized fibular harvest is that the donor site regenerates new bone provided periosteum is preserved. We prospectively investigated the regenerated fibula quantitatively and studied clinical implications of non-regeneration.
Material and methods
The fibula was harvested using a periosteum preserving technique. Only fibulae from healthy legs were harvested. X-rays were done pre- and post-operatively at three and six months. Clinical assessment of donor limb included pain, gait, motor and sensory examination. Fibular regeneration was quantified using defined length and width criteria.
Results
There were 16 children with 21 harvested fibula. About 65 % of total fibular length was available for use as graft. There was regeneration of fibula similar to the pre-operative dimensions as early as six months in 71 % of cases. There were no clinical morbid findings as assessed at six months follow up despite non-continuity being observed in 29 % of cases. The predominant site for non-continuity was middle third-distal third junction.
Conclusions
Periosteal preserving non-vascularized fibula grafting was a low morbidity procedure. In two-third of the cases, there was regeneration of fibula comparable to pre-operative dimensions as early as six months. The non-continuous regeneration had no clinical implications.
