Osteoarticular disorder characterized by the presence of a typical facial appearance, cleft palate, and underdeveloped bowed femurs.

Bilateral Femoral Dysgenesis; Femoral Dysgenesis-Robin Anomaly; Femoral Hypoplasia-Unusual Facies Syndrome.

Mostly sporadic but autosomal dominant forms with incomplete penetrance have been reported.


Mainly clinical and usually can be suspected antenatally during routine ultrasonogram.

Affected patient presents with a facies characterized by up-slanted palpebral fissures. Micrognathia associated with a small, pointed chin, short nose, thin upper lip, long philtrum, and cleft palate is found in some cases. The musculoskeletal findings show mainly short, bowed femora and acetabular and sacral anomalies, resulting in a short stature. All other bone lengths are within normal. Some of the other features are hypoplasia of the penis, testes, and labia major and possible renal abnormalities.

No special precautions required before administration of anesthesia except for careful evaluation of the airway in the presence of micrognathia. Evaluate renal function.

The potential for difficult direct laryngoscopy and tracheal intubation cannot be eliminated. Because of musculoskeletal involvement, special attention to intraoperative position must be given.

No specific implications with this condition. Limit use of prolong neuromuscular relaxants once the trachea has been secured.
