Dear Ali

Conradi-Hünermann syndrome is a rare genetic disorder characterized by skeletal malformations, skin abnormalities, cataracts and short stature. The specific symptoms and severity of the disorder may vary greatly from one individual to another

The treatment of Conradi-Hünermann syndrome is directed toward the specific symptoms that are apparent in each individual. Such treatment may require the coordinated efforts of a team of medical professionals, such as pediatricians; physicians who diagnose and treat disorders of the skeleton, joints, muscles, and related tissues (orthopedists); skin specialists (dermatologists); eye specialists; and/or other health care professionals.

Various orthopedic measures, including surgery, may be recommended to help prevent, treat, or correct certain skeletal abnormalities associated with the disorder. Surgery may also be advised for certain craniofacial malformations, scoliosis or other physical abnormalities. The surgical procedures performed will depend on the nature, severity, and combination of anatomical abnormalities, their associated symptoms, and other factors.

Genetic counseling may be of benefit for affected individuals and their families. Other treatment is symptomatic and supportive.

I dont have experience with this syndrome but i think the treatment of hip dislocation, when indicated, should be similar to the treatment of teratological  congenital hip dislocation . The conservative treatment does not provide good results. Surgeries can range from removal of soft tissue interposition, through femoral osteotomy and pelvic osteotomies
