“…Although radiofrequency ablation has been reported as one option for the treatment of chondroblastoma in the literature [15][16][17]37 , the mainstay of treatment remains surgery. Specifically, meticulous curettage of the lesion followed by bone-grafting is the gold standard 13,21,38 .…”

“…Several case reports have demonstrated that RFA can be applied to the periarticular area, especially the femoral head, proximal humerus, femoral condyle and tibial plateau. [2][3][4]7,8 In difficult areas, such as the femoral head, several case reports and case series have shown that RFA has had excellent outcomes in terms of head preservation, no growth plate damage and no tumor recurrence ( Table 1). The decision to treat with RFA is based on skeletal maturity and size of the lesion.…”

C hondroblastoma is rare, representing only 1-2% of all primary bone tumors and 5% of benign bone tumors. 1 Most patients are under 20 years old. Chondroblastoma is usually located in the epiphysis or apophysis of long bones but it can occur in flat bones and vertebrae as well. 1 Symptoms vary from mild to severe pain for periods followed by a decrease in range of motion. The standard treatment of chondroblastoma is tumor curettage with a bone graft. 1 Management of chondroblastoma in the femoral head, however, is challenging due to the difficulty of access and the potential risk of damage to the epiphyseal plate. Radiofrequenct ablation (RFA) is a minimally invasive option for chondroblastoma management. Reports of a small series using this technique have been reported to have had excellent outcomes, but there is limited data on long term follow up. 1-5 Case ReportA 13-year old boy presented to the Orthopedic Out-patient Clinic in January 2012 with left hip pain and reported limping for 1 year. He also had night pain but no history of trauma to the left hip. His mother had brought him to a primary hospital where he was initially treated with NSAIDs but the pain did not subside. Physical examination at the Orthopedic Clinic revealed a left antalgic gait and tenderness at left groin with slightly limited internal rotation of the left hip.Plain radiographs showed an eccentric well-circumscribed osteolytic lesion at the epiphysis of the left femoral head which measured 1.5x1.5 cm (Figure 1). Preoperative CT scans of the left hip showed a welldefined homogeneous osteolytic lesion 1.3x1.7x1.4 cm with a sclerotic border at the left femoral epiphysis (Figure 2). The inferior margin of the lesion was located on the epiphyseal plate of the femoral head while the superior margin was located beneath the articular surface.Based on the pathology report, chondroblastoma of the left femoral head was diagnosed. To avoid risk of growth plate injury following open surgery, we chose percutaneous radiofrequency abrasion. AbstractSurgical management of chondroblastoma of the femoral head in skeletal immaturity is challenging due to difficult access and a risk of epiphyseal plate injury. A 13-year old boy presented with left hip pain and limping for over 1 year. Based on imaging and pathology report, chondroblastoma was diagnosed. The size of the tumor was 1.7 cm in diameter. To avoid epiphyseal plate and articular damage, percutaneous radiofrequency ablation was performed under fluoscopic guidance with a 70 o Celsius monopolar probe for 3 minutes' duration repeated 3 times. The 2 nd ablation procedure was performed after 3 months to minimize risk of recurrence. The pain had subsided at the 3 months follow up. Over the 4 years follow up period, this case shows good functional outcome without deformity of the femoral head or tumor recurrence.

“…66 There has been recent interest in these modalities for other indications, such as RFA for chondroblastoma, 67 with all patients showing involution of their lesion with fatty replacement. Embolization of vascular lesions also has been used as an alternative or as an adjunct before surgery, in lesions such as ABC and GCT in locations that pose surgical challenges, such as the spine and the sacrum.…”

Adjuvant treatment of non-malignant active and aggressive bone tumors

Aggressive but nonmalignant bone tumors often pose a difficult therapeutic dilemma for orthopaedic oncologists. Intralesional surgery usually is the modality of choice to lessen the morbidity associated with a marginal or wide excision. With more aggressive tumors, such as giant cell tumor of bone, chondroblastoma or aneurysmal bone cysts, high recurrence rates after curettage alone present a challenge to the surgeon. Adjuvant therapies provide an additional means of clearing the cavity of tumor cells after aggressive intralesional resection. The addition of adjuvants then is able to extend the margins beyond that which is visible to a marginal excision, removing microscopic disease. Clinically, this yields lower recurrence rates, with different methods having better efficacy. With the less aggressive yet still active lesions, injections and percutaneous methods may be preferred.This article discusses some of the more common as well as emerging trends in adjuvant therapy for active and aggressive nonmalignant bone tumors. Broad categories included are mechanical (burring), hypothermic or hyperthermic (cryotherapy, argon beam, cementation), chemical (phenol, hydrogen peroxide), and biologic modalities (bisphosphonates). Injectable materials also are discussed. Current literature regarding these adjuvants (focusing on the past 2 years) is presented, with an eye on clinical recommendations.

Radiofrequency ablation of chondroblastoma: procedure technique, clinical and MR imaging follow up of four cases

Abstract: Radiofrequency ablation for chondroblastoma provides an alternative to surgical curettage, and we have demonstrated both a clinical improvement in symptoms and the follow-up MRI appearances.
