Chondroblastoma of the Talus Treated with Osteochondral Autograft Transfer from the Lateral Femoral Condyle

Abstract

Chondroblastoma is a benign cartilaginous lesion of bone. When occurring in a position juxtaposed to articular cartilage, treatment is directed at removal of the tumor with preservation of the articular cartilage. In this case, a chondroblastoma of the talus with erosion into the articular cartilage was treated with transfer of an osteochondral autograft from the ipsilateral femoral condyle. At two-year follow-up, the patient was symptom free and magnetic resonance imaging revealed complete incorporation of the graft. This case is presented as a representative example of osteochondral autograft transfer surgery (OATS) for the treatment of chondroblastoma.

Aggressive chondroblastoma of the acromion in a forty-one-year-old patient

“…1,16,17 Recurrences have been reported in 10 to 45% after surgical treatment. 16,17 Bloem reported no recurrence after 3 years follow-up in patients treated with curretage and grafting.…”

“…5,9,15 Chondroblastoma has a predilection for the secondary ossification centers of long bones. 1,5,11,16 The most common location is about the knee (distal femur and proximal tibia), followed by the proximal humerus. 5,6,9 The talus, calcaneus, patella, cuboid, metatarsals, metacarpals, and triquetrum are other rare locations.…”

“…It also occurs in the small bones of hand and feet, such as the talus, calcaneus, cuboid, and metatarsals. 1,5,6,9,11,16 Acromial involvement is very rare, with only 2 reported cases. 8,19 The mainstay of treatment for CB is surgical excision of the lesion and filling the defect with bone grafts or synthetic materials.…”

“…8,19 The mainstay of treatment for CB is surgical excision of the lesion and filling the defect with bone grafts or synthetic materials. 1 We present an unusual case of a 41-year-old male with CB, which originated from the acromion and subsequently involved the adjacent soft tissues, that was treated with resection and allograft bone grafting.…”

Tumores ósseos benignos e lesões ósseas Pseudotumorais: tratamento atual e novas tendências

“…Cirurgia com transferência de autoenxerto osteocondral pode ser realizada para tratamento de tumores benignos justapostos à cartilagem articular e com erosão da mesma. O enxerto geralmente é removido do côndilo lateral do fêmur (33) . O aloenxerto seria menos desejável pelo risco de rejeição imunológica, potencial para transmissão de doenças, infecções e inferioridade biológica para incorporação.…”
