Severe life-threatening hypersensitivity reaction to polidocanol in a case of recurrent aneurysmal bone cyst.

Aneurysmal bone cysts (ABC) are expansile lytic lesions constituting around 1% of all benign bone tumors with an annual incidence of 1.4/100000. A variety of treatments are available ranging from curettage with or without bone grafting (autologous or allogeneic), curettage with use of adjuvants [Polymethylmethacrylate (PMMA) bone cement, high speed burr, phenol, liquid nitrogen], wide en-block excision with or without reconstruction, selective arterial embolization of the feeding vessels, radiation therapy, high precision megavoltage radiotherapy and percutaneous radio-nuclide ablation, sclerotherapy (ethibloc, aetoxisclerol, alcohol gel, polidocanol).

Mega Prosthetic Replacement of Elbow for Resistant Nonunion of Distal Humerus.

Introduction: Fractures of the distal humerus are a rare entity accounting for approximately 2% of the humeral fractures. Non union of the distal humerus is further rare and poses a major challenge. These fractures usually respond to open reduction and bone grafting but some may fail multiple surgical attempts at union and hence are labelled as "resistant" non union.
