Purpose: The purpose of this study was to report impacts of the amount of displacement of percutaneous osteotomy on the clinical and radiologic results in the treatment of bunionette deformities.
Materials and Methods: We retrospectively reviewed 36 cases of bunionette deformities treated with percutaneous modified Kramer osteotomies from 2009 to 2013. We measured amounts of displacement on anteroposterior and lateral plain radiographs as well as multiple parameters which represent degrees of the bunionette deformities. We also recorded radiological healing time, clinical healing time, residual symptoms, and the time of returning to daily activity.
Results: No meaningful correlation was found between severity of preoperative deformity and amount of displacement of the osteotomy. The amount of displacement on a horizontal plane did not affect the healing time, duration of symptoms, or time of returning to daily activity. However, large sagittal displacement was related to duration of postoperative symptoms.
Conclusion: Findings of this study suggest that the displacement in percutaneous osteotomy for bunionette deformity does not affect clinical results and healing time. We believe that we do not need to be excessively cautious about how large the displacement we make during the percutaneous modified Kramer osteotomy for the bunionette deformity.
