Proximal Tibial Physeal Frx:
- Discussion:
- tibial tuberosity forms at about 13 wks of gestation, as cartilaginous extension of proximal tibial epiphysis;
- epiphyseal ossification center of proximal end of tibia appears at 1-3 months;
-
primary ossification center:
- center does not reach tibial eminence until late childhood;
- center slowly enlarges toward secondary ossification center of the tibia;
- proximal tibial physis contributes approx 55 % of length of tibia, approx 25 % of length of
limb, & approx 0.25 inch (0.64 cm) / yr until maturity;
-
secondary center:
- ossification develops in distal aspect of tuberosity at approx
8 years;
- physis of tuberosity closes between ages of 13 & 15 yrs in girls &
between ages of 15 & 19 yrs in boys;
- epiphyseal center of tibial tuberosity fuses w/ prox tibial epiphysis at age of 17 years;
