Banki syndrome

Banki syndrome is an extremely rare inherited skeletal disorder characterized by a combination of specific bone and joint abnormalities primarily affecting the hands and wrists. The condition was first described by Banki in 1965 in a Hungarian family. The hallmark features include clinodactyly (abnormal curvature of the fingers), brachymetacarpia (shortened metacarpal bones), and an abnormal shape of the lunate bone in the wrist (described as bipartite or fused lunate). Affected individuals may also demonstrate radial deviation of the fingers and other subtle skeletal anomalies of the upper extremities. The syndrome primarily affects the musculoskeletal system, specifically the bones and joints of the hands and wrists. The clinical presentation is generally mild, and the condition does not typically involve intellectual disability or major organ system dysfunction. The skeletal findings are usually noted in childhood and may be identified incidentally on hand radiographs. Because the condition is so rare, with only a small number of families reported in the medical literature, the full clinical spectrum may not be completely delineated. There is no specific curative treatment for Banki syndrome. Management is symptomatic and supportive, focusing on orthopedic evaluation and intervention if functional limitations arise from the skeletal abnormalities. In most cases, the hand and wrist anomalies do not cause significant disability, and affected individuals can lead normal lives. Genetic counseling is recommended for affected families to discuss the inheritance pattern and recurrence risk.
