Abstract

Multiple drilling of the femoral head is a commonly-used surgical technique for the treatment of osteonecrosis. Several holes are drilled into the femoral head using a small-diameter Steinmann pin. This decompression technique promotes revascularization and regeneration of necrotic tissue in the femoral head. Known complications are heterotopic ossification and femoral subtrochanteric fractures, although these have only been rarely reported. Our case study focuses on a subtrochanteric fracture 6 weeks after a multiple drilling operation.
