Chondroblastoma

Abstract

Purpose.To review all patients with chondroblastoma treated in our hospital between 1993 and 2004. Methods. Six men and 4 women aged 13 to 33 (mean, 21) years with histologically proven chondroblastomas were retrospectively reviewed through our tumour registry, patient records, radiographic and histopathologic reports. All patients underwent intralesional curettage and bone grafting with or without bone cement. The mean follow-up period was 5.5 (range, 2-11.8) years. Functional outcome was measured according to the Enneking scoring system. Results. The proximal tibia and femur were the most frequently involved sites. All patients presented with pain but only 2 with joint effusion. In 3 patients the lesions were aggressive, in 3 others it was active, and in 4 it was latent. In 2 patients the lesions recurred at 5 and 28 months; both resolved after repeat surgeries without further recurrence. Functional outcomes were either good or excellent, except for one patient with a compartment syndrome of the contralateral leg. No patients had metastasis to lungs or collapse of articular surfaces. Conclusion. Chondroblastoma is a rare benign bone Chondroblastoma IE Garin, EHM WangMusculoskeletal Tumor Unit, Department of Orthopedics, Philippine General Hospital, University of the Philippines, Manila, Philippines Address correspondence and reprint requests to: Dr Edward HM Wang, Musculoskeletal Tumor Unit, Department of Orthopedics, Philippine General Hospital, University of the Philippines, Manila 1000.

Radiological findings in 31 patients with chondroblastoma in tubular and non-tubular bones

“…(1,2) It typically develops from the epiphysis of skeletally immature patients. (3,4) Peak incidence of CB is seen in the second decade of life, (5,6) and has been reported to occur more frequently in men than in women. (5,(7)(8)(9)(10) Although CB has a predilection for tubular bones such as the humerus, femur, tibia and metatarsus, (7,11) it can also be found in non-tubular bones (NTBs) such as flat bones (i.e.…”

Lower recurrence rate in chondroblastoma using extended curettage and cryosurgery

“…Curettage, either alone or in conjunction with bone grafting using autogenous or allogeneic bone graft or both, have been described [1,2,4,8,10,13]. Packing the cavity with polymethylmethacrylate is another advised treatment modality [5,[13][14][15].…”

“…Chondroblastoma accounts for approximately 1-2 % of all primary bone tumours [8]. It usually occurs in adolescents and young adults [2,9], whereby males predominate with a ratio of 3 to 2 [3,10].…”

Unusual presentation of chondroblastoma mimicking Trevor's disease

“…It is well circumscribed lytic lesion limited to the epiphysis but in some cases may extend to involve the metaphysis leading to endosteal expansion or cortical destruction with periosteal new bone formation known as neocorticalization. [8] Despite epiphyseal involvement, joints adjacent to chondroblastoma are not involved. The case presented here had an intra-articular extension of the tumor from the medial tibial epiphysis with clinical restriction of joint movement similar to the presentation of intra-articular osteochondroma.…”
