Resumen (ES)
A triangular implant compound by 3 metallic
screws united by a filament (PDS II® vs. Tendofil®) as
method of experimental epiphysiodesis was evaluated.
They were used 32 immature rabbits, divided into 4 Groups
according to the follow-up (1.2.3 and 4 months), and subdivided
according to the employed filament. The implant was
located at the lateral face of the distal left femoral epiphysis.
The right extremity served as control. Radiographic, histologic
and histomorphometric studies were performed. The
oporated legs presented a significant valgus deviation as
compared to controls. The epiphysiodesis was achivied
with both tipes of filaments. During the first month, the efficiency
of the absorbable implant was comparable to the
metallic. Thereafter, the metallic implant results more effective.
Histologic and morphometric studies showed the
hemiepiphysiodesis. No physeal damaged in relationship to
the degradation of the absorbable implant was observed.
Our results suggest the use of absorbable implant in growth
plate surgery.
