Fresh-frozen Osteochondral Allograft Reconstruction of a Giant Cell Tumor of the Talus
ABSTRACT The use of fresh-frozen osteochondral allografts has been reported for the treatment of talar fractures, osteochondral lesions, and tumors of the calcaneus. Currently, we are unaware of any reports in the literature addressing the use of fresh-frozen osteochondral allograft for the treatment of giant cell tumors in the talus. We report our attempt to eradicate an aggressive giant cell tumor of the talus while minimizing morbidity and loss of function via reconstruction with a fresh-frozen osteochondral allograft. This is the first report in the literature to propose such a treatment option for giant cell tumors in the talus. The patient was informed that a report of this case would be submitted for publication.

- "Case reports may not be representative of the overall benign and malignant primary tumours affecting the talus with many case reports describing investigatory    or treatment techniques    . Case reports have identified a wide spectrum of benign and malignant bone tumours including intraosseous ganglion , unicameral bone cyst , intraosseous haemangioma , osteoblastoma , chondroblastoma [10,22–31], osteochondroma , osteoid osteoma [12–14,16,17,33], aneurysmal bone cyst , giant cell tumour , osteosarcoma         , chondrosarcoma    , Ewing's sarcoma   and solitary myeloma .

ABSTRACT: Primary bone tumours of the talus are rare and the existing literature is limited. The aim of this study was to investigate the epidemiology of primary bone tumours affecting this uncommon site and suggest a management protocol for these tumours. We retrospectively reviewed the Scottish Bone Tumour Register from January 1954 to May 2010 and included all primary bone tumours of the talus. We identified only twenty three bone tumours over fifty six years highlighting the rarity of these tumours. There were twenty benign and three malignant tumours with a mean age of twenty eight years. A delay in presentation was common with a mean time from onset of symptoms to diagnosis of ten months. Tumour types identified were consistent with previous literature. We identified cases of desmoplastic fibroma and intraosseous lipodystrophy described for the first time. We suggest an investigatory and treatment protocol for patients with a suspected primary bone tumour of the talus.Foot and Ankle Surgery 12/2012; 18(4):277-82. DOI:10.1016/j.fas.2012.04.007

ABSTRACT: A two-dimensional measurement technique based on the electro-optical Kerr effect for electrical field distribution in dielectric liquids is described. The optic phase distribution of light is modulated in square pulsed mode by optical and electric modulations respectively. To decrease the effect of the noise component resulting from the electro-hydro-dynamic motion of the dielectric liquid, a diagnostic image lock-in amplifier technique is proposedProperties and Applications of Dielectric Materials, 1997., Proceedings of the 5th International Conference on; 01/1997

ABSTRACT: Giant cell tumor of talus is a rare entity. In contrast to GCT of long bones, most cases occur in a younger age group and tend to be multicentric. The authors report a case of GCT in a 19 year old boy which had led to extensive destruction of the talus. In view of the extensive involvement, total talectomy along with tibio - calcaneal arthrodesis was performed. At 6 months of followup, the patient had a painless and well arthrodesed ankle. There was no evidence of recurrence at 18 months of followup.Cases Journal 02/2009; 2(1):74. DOI:10.1186/1757-1626-2-74
