Hip morphology and its relationship to pathology: Dyplasia to impingement

Developmental dysplasia of the hip (DDH) and femoroacetabular impingement are conditions that occur in adolescents and young adults that cause hip pain. The morphology of both conditions will be discussed as they relate to pathology. Radiographs taken in both conditions many times are read as “normal.” On careful analysis, these conditions can be easily seen on radiographs. Reinhold Ganz with the Bern Hip Group and Jeff Mast have developed outstanding open techniques to correct both with a periacetabular osteotomy to correct DDH and a safe surgical dislocation of the hip to alleviate femoroacetabular impingement. Although not correcting the structural defects in DDH, arthroscopy may be helpful in alleviating pain. An arthroscopic equivalent to the open surgical dislocation of the hip will be presented. The early results are favorable.
