A disorder that results in anatomical anomalies of the hands and feet.
Triphalangeal Thumbs and Brachyectrodactyly Syndrome.
The few cases reported relate to four kindreds mainly from Mexico.
It occurs either sporadically or as an autosomal dominant inherited syndrome with highly variable expression.
Based on the clinical findings.
These findings are principally restricted to the extremities and include triphalangeal thumbs, brachy(syn) dactyly of the index fingers and third toes and occasionally ectrodactyly of the hands and feet. Short stature, ectrodactyly (more often of the feet than of the hands), and onychodystrophy occasionally occur.
Precautions before anesthesia
Routine preoperative assessment.
Anesthesia for patients with this condition has not been reported. The mainly peripheral nature of the features and the absence of associated organ dysfunction suggest no specific precautions should be necessary. Peripheral vascular access could be challenging if ectrodactyly is severe.
None specific to this disorder.
