Replacement of epiphyseal bone with methylmethacrylate: Its effect on articular cartilage

Abstract: Methylmethacrylate cement was used as a substitute for the epiphyseal bone of the canine proximal femora, after femoral neck osteotomy. The effects of different volumes of acrylic cement on the integrity of trabecular bone and articular cartilage and the effects of different types of fixation of the osteotomy site were assessed clinically, radiologically and histologically. Degenerative changes occurring in the articular cartilage were greatest when a large area of epiphyseal bone was replaced with methylmetha… Show more

“…Various materials have been employed in augmenting bone defects, but none have proven ideal. [1][2][3][4][5] Autogenous bone graft, considered to be a most ideal material, has been conventionally employed. However, when the osseous defect is large, it is difficult to augment it by autogenous bone alone, and furthermore, its use is restricted by donor-site morbidity and blood loss.…”

“…PMMA has a modulus that is between cortical bone and cancellous bone and well above articular cartilage. PMMA acts as a rigid surface, concentrating pressure on the already thin cartilage and subchondral plate tissue [13,15,24]. This may result in cartilage damage, fracture, and arthrosis [13,15,28].…”

“…PMMA acts as a rigid surface, concentrating pressure on the already thin cartilage and subchondral plate tissue [13,15,24]. This may result in cartilage damage, fracture, and arthrosis [13,15,28]. Bone graft has the ability to incorporate into host bone and more adequately restore the subchondral and cancellous positions of the joint surface [7,8,32].…”

“…Hence, its use in lesions involving the head and neck of the femur may result in an increased chance of fractures through cement. There is also fear about long-term degeneration of articular cartilage in subchondral lesions in weight-bearing areas, 7 infection and difficulty in removing on revision procedures.…”
