Intercalary bone grafting for the reconstruction of phalangeal osteolysis in disappearing bone disease: case report.

Disappearing bone disease (DBD) is a rare condition of unknown etiology that may cause massive hand deformity due to severe osteolysis and soft-tissue atrophy. Bone grafting of the affected metacarpal bones or wrist has been described with moderate success in only 4 cases, but phalanx reconstruction has not been attempted. We report a case with multicentric DBD that was treated with staged intercalary iliac bone grafting of the phalanges of the dominant thumb and index finger. After 3 years, no graft resorption was noticed and the patient reported considerable functional improvement.
