Kirner deformity has minimal impact on finger function, except in a few populations such as musicians and keyboard operators, where the primary goal of correction is to improve the shape of the finger, so the indications for surgery are narrow. Long-term wear of a series of straightening braces starting early, before growth is complete, may have some effect in correcting the deformity. Surgery is generally postponed until the patient can participate in the decision to operate. Osteotomies may be used to correct the finger bone force line and nail deformity, including a dorsal closed osteotomy or 2-3 open osteotomies in the palmar cortex to straighten the finger bone, with longitudinal penetration of the Kirschner pins for fixation, and braces to protect the finger during healing. The deformity has also been reported to be corrected using a distraction lengthening technique. The correction of Kirner deformity of the little finger may seem simple, but it is technically challenging and requires sufficient experience. The possible risks of surgery, such as delayed healing of the infected bone, must be explained in detail to the patient, and the result may be a slightly shorter than normal end phalanx and incomplete straightening of the little finger.
