| Summary: | Fracture is a bone damage. Many methods have been developed to speed up
the healing of fractures, one of which is the use of intramedullar pin. This study
was aimed to determine the effect of fracture healing with intramedular pin
through changes in the number of osteoblasts.
Sixteen 3 months old male white rats strain Sprague dawley with average
weight 247 grams, were divided into two groups. Each group has 8 rats. The first
group (A) as a control group and the second group (B) as treatment group.
Repositioning surgery left femur fracture in whole rat was done after adapted for 1
week. Group B was given intramedullar pin as a tool fixator. Necropsy was
performed at 0, 1st, 2nd, and 4th week after surgery. Histopathological
observations was done of broken bones to count the number of osteoblasts. A twoway
ANOVA test with two factors (time and intramedullar pin) was used to
analyze data.
Statistical analysis showed that there is significant difference in the amount
of osteoblast between Group A and Group B (p<0,05). Based on these result, it
can be concluded that the use of intramedullar pin can increase the number of
osteoblasts thus accelerate fracture healing of long bones.
