Zusammenfassung:Purpose This study investigated the effects of multiple drilling on the immature capital femoral epiphysis following ischemic injury in a piglet model. Materials and Methods Ischemic necrosis of capital femoral epiphysis was induced bilaterally in 12 piglets using a cervical ligation method. Three weeks later, medial, central, and lateral 3 drill holes were made on the left femoral head using 0.062" K-wire. At 3, 6, 9, and 12 weeks following the multiple drilling, femoral heads were harvested from each three piglets. On histologic examination, percent of revascularization, percent of osteoblast surface, capital femoral epiphyseal quotient and proximal femoral growth plate height were evaluated. Untreated right femoral heads served as control. Results While percent of revascularization of left capital femoral epiphysis with multiple drilling was significantly higher than untreated control side (p
