The April June 2014 issue of the journal brought to us an interesting case of valgus deformity caused by dysplasia epiphysealis hemimelica in the knee and we wish to present an addendum. Dysplasia epiphysealis hemimelica can be classified according to Auzoz et al. into three types i.e. localized or monostotic type, classical type with more than one area of involvement in a single lower limb (knee, ankle) and a generalized or severe type with involvement of entire lower limb (pelvis to foot). A bone scan is the preferred modality of investigation in these patients as compared to radiological skeletal survey for the assessment of entire skeletal system. An arthrogram is useful for the assessment of articular surface and joint involvement. It evaluates the extent of cartilaginous mass and detects the epiphyseal plate involvement.
