Management of recurrent hip dislocation in Down Syndrome using modified Ganz periacetabular osteotomy: Follow up after 5 years.

Recurrent hip dislocation in a Down Syndrome patient with dysplastic hip is a very rare and challenging case to treat even for an expert orthopaedic hip surgeon. Least compliant patient and family, lowly educated with low socioeconomic status, young age and several anatomical variations forces limited option as a treatment. Several literatures mentioned Despite requiring only minimal implant, this technically demanding surgery requires a thorough understanding of the hip anatomy. This is the first case worldwide reporting 5 year follow up of dysplastic hip with DS treated successfully with periacetabular osteotomy (PAO) technique. An eighteen years old female with DS had multiple posterior hip dislocation episodes since 3 years prior our hospital admission. A modified Ganz PAO was performed under image intensifier guide. Patient was able to talk and hip was never dislocated again within 5 years follow up. Ganz periacetabular osteotomy, although a technically demanding surgery, is a preferable treatment in recurrent hip dislocation for Down Syndrome patient with good to excellent clinical and radiological outcome.
