Abstract
Total hip arthroplasty in cases of dwarfism may be a demanding procedure, as the small-sized joints are difficult to replace with standard prostheses, even more so in the presence of dysplastic hips. The authors report a case of bilateral customized total hip arthroplasty performed in a young patient with proportionated dwarfism with bilateral hip dysplasia. To ensure sufficient stabilization of the cup, roof bone grafting was performed. The custom-made acetabular component was a trabecular acetabular shell manufactured using selective laser melting technology to ensure an optimal porous structure to enhance primary stability and bone ingrowth. Selective laser melting may be a promising alternative technology for manufacturing highly porous customized acetabular components for complex joint reconstruction procedures in which enhanced osseointegration ability is particularly required.
