Hydatid Disease of bones and joints

Hydatid disease commonly affects the liver and lungs. The bones and joints are involved in 1-2% of total hydatid disease cases. Two cases of osseous hydatid disease seen recently are being reported. One male patient who had hydatid disease of the humerus, presented as pathological fracture and another female patient presented with tumour like mass in the sacral area. At operation extensive currettage and lavage was done in both the cases. The humerus was then fixed with K-nail. This patient developed recurrence which was subsequently operated with currettage, lavage, K-nail refixation and bone cement filling. On 5 to 15 months follow-up both patients are doing well without signs of recurrence and the fracture has united well
