Simple curettage without bone grafting for enchondromas of the foot

Background Simple curettage without bone grafting for enchondromas of the hand and its good clinical results have been reported. Yet, there have been no reports regarding simple curettage without bone grafting for enchondromas of the foot. The purpose of this study is to elucidate the clinical results of this method for enchondromas of the foot.Methods We studied eight patients (ten bones) with enchondromas of the foot treated with simple curettage without bone grafting. After making an oval or round fenestration, the enchondroma was curetted. The cortical window of the fenestration was excised in five bones, whereas it was replaced at the fenestration site in the other five bones.Results The affected toe was immobilized with a tape in two patients. All patients began to walk on the day of surgery or the next day without crutches. Sclerotic changes on the plain radiographs were seen 6.4 weeks (range: 4–10 weeks) postoperatively. The patients returned to their normal daily activity including occupation and sport in 8.6 weeks (range: 0–12 weeks) postoperatively. The radiographic appearance was almost normalized in 8.4 months on average (range: 3–14 months). Function was classified as excellent in all bones according to a modified Tordai classification.Conclusion We conclude that simple curettage without bone grafting can be one of the standard surgical treatments for enchondromas of the foot.     

Treatment of a simple bone cyst of the calcaneus by endoscopic curettage with cancellous bone injection

The authors report a case of simple bone cyst involving the calcaneus, treated by curettage under endoscopy with cancellous bone injection, and its course and follow-up at two years. This new technique has not yet been published for simple bone cysts of the calcaneus. Endoscopic curettage of the cavity of a simple bone cyst can be advocated for the calcaneus to minimize incisions and to avoid cutaneous complications.     

Interdisciplinary treatment strategy of aneurysmal bone cyst]

In this report the management of an aneurysmal bone cyst in the cervicothoracic region of an 13-year-old girl is described. Aneurysmal bone cyst is a histologically benign lesion that is often extremely vascular. In the spine, it can cause extensive bone destruction and compress neural structures and this can result in high-grade tetraparesis. In the treatment a three-stage operation with radical total removal of the cyst from two posterior approaches and one anterior approach for osteosynthetic stabilisation gave an excellent result. The value of preoperative embolization to reduce tumor vascularity, allowing total excision without neurological deficits to the patient, is demonstrated.     

Subperiosteal aneurysmal bone cyst

Aneurysmal bone cyst of long bones in a subperiosteal location is unusual. We report such a case, and the importance of radiological and pathological examination is emphasized. The diagnosis of subperiosteal aneurysmal bone cyst should be considered in the presence of subperiosteal lytic lesions of the long bones.

Sphenotemporal aneurysmal bone cyst. A new case and review of the literature

Aneurysmal bone cysts (ABC) are benign tumors of the bones, formed by multiple cysts filled with blood and eroding the bone. They are rarely located at the skull. We report a case of a right temporal ABC in a 5-year-old girl. On admission, the physical examination showed a tough and fixed tumor, with no inflammatory signs nor vascular characteristics. The neurological examination was normal. Imaging studies showed an heterogeneous extracerebral mass, eroding the temporal bone and the greater wing of the sphenoid bone. The treatment consisted in an extensive tumor resection, associated with reconstructive surgery. The outcome was uneventful (follow-up 27 months). We underline the pathogenetic, diagnostic and therapeutic features of this condition.     

Treatment of aneurysmal bone cyst]

The authors present the results of surgical treatment of 16 cases of aneurysmal bone cyst between 1998 and 2000. Age of patients at the onset of symptoms ranged from 5 to 15 years (average 11.3 years). In 12 cases the cysts were aggressive, and in 5 cases they were active (according to the capanne classification). In 12 cases the characteristic lining of the cyst was removed, curettage was performed and bone grafts were inserted into the bone cavity. In 3 cases autografts were used, in 2 cases both allografts and autografts were used, and in 7 cases only allografts were applied. Two cysts of the fibula were removed en-bloc, a cyst located in the scapule was treated with radiotherapy. In 15 cases the cyst was successfully managed surgically. While in 1 case a revision procedure was performed.     

MRI Diagnosis of aneurysmal bone cyst

80–90% of individuals suffering from aneurysmal bone cyst (ABC) are children or adolescents. Primary ABC is a non-neoplastic lesion. Diagnostic assessment and detection of recurrence demands repeated plain x-rays or CT scans. These repeated radiographic examinations expose these young patients to large doses of ionizing radiation. Magnetic resonance imaging (MRI) is found to be an effective and reliable noninvasive technique for the diagnosis and follow-up controls of ABC.     

Spontaneous regression of aneurysmal bone cyst

Summary Generally, aneurysmal bone cyst is considered to be a benign lesion that occurs rarely. Its etiology and treatment vary considerably, but curettage and grafting is the widely accepted treatment. Due to the nature of the disease recurrence is always expected. It rarely regresses and we report here a case that showed an improvement spontaneously after open biopsy. Follow-up for more than 4 years has shown no progression.     

Primary aneurysmal bone cyst of patella

Of all the aneurysmal bone cysts (ABC) occurring in the body, less than 1% are seen in the patella. We report here, a 27-year-old woman with Stage III ABC of patella. Curettage, chemical and thermal cautery of the bed followed by autogenous bone grafting of the defect was done. At two-year follow up, there was a suspicion of lucency in the middle of the patella. However a repeat curettage revealed only fibrous tissue. Now at four years of follow up, the bone graft remained well incorporated. Patient has mild anterior knee pain on stair climbing but regained normal knee function.

Endoscopic curettage and bone grafting of huge talar bone cyst with preservation of cartilaginous surfaces: Surgical planning

Open curettage and bone grafting of the huge talar cysts may need extensive soft tissue dissection or even different types of malleolar osteotomy to access the lesion. Arthroscopic approach can minimize soft tissue dissection or the need for malleolar osteotomy. Careful pre-operative planning of the portal sites allows endoscopic curettage and bone grafting of the lesions with preservation of the articular surfaces.     

Roentgenographic and computed topographic observations on benign bone tumor and tumor-like lesions treated by simple curettage without bone grafting

Curettage without bone graft was performed in fifteen patients with benign bone tumors and tumor-like lesions. We studied the bone formation after curettage by plain radiography and computed tomography for six or more months. Average period before full-weight-bearing in thirteen patients of the lower extremities was three and a half months. We found no pathological fractures after curettage in any of the patients. Increases in radiodensity and reconstruction of the bone were observed in serial plain radiographs within three months. Computed tomography revealed that the center of the lesions persisted without bone formation, although thickening of cortex bone was predominant. From the data obtained here, it appears that bone grafts may not be necessary in patients, especially in younger ones, with benign bone tumors and tumor-like lesions.
