Clinodactyly, finger deviation in the coronal plane, affects the little finger most commonly. Patients typically tolerate clinodactyly without functional limitation, but with increasing deformity, they may have difficulties with specific tasks such as playing musical instruments. In those who do not tolerate the deformity, surgical options include physiolysis for young patients and osteotomy for older patients. An opening wedge osteotomy increases finger length while correcting the coronal deformity. Surgical results of the opening wedge osteotomy are satisfying and complications are rare, with stiffness of the distal interphalangeal joint noted in some patients.
