Corticoplasty for improved appearance of hands with ollier disease

Purpose: Only a few treatment options are available for Ollier disease, especially for improving appearance. The purpose of this study was to evaluate the efficacy of partial resection of the cortical bone with curettage of the tumor (corticoplasty) for treating hand deformity in Ollier disease. Methods: Five hands (3 patients, 30 metacarpals and phalanges) were examined. Windows of thin cortical bone were elevated, the tumors were excised, and the cortex was trimmed and replaced to enhance the appearance. Artificial bone substitute was used as the graft material for 17 lesions to fill the vacant medullary cavity. The other 13 bones had corticoplasty without grafting. Reduction of bone diameter on radiographs and patient satisfaction were rated after an average of 24 months. Results: On average, bony union was achieved 9 weeks after surgery (range, 4-12) in all cases. Morphologic changes on radiographs were rated as excellent or good. Complications and tumor recurrence were not observed, and the range of finger motion and grip strength did not decrease. The level of satisfaction with the outcome was very satisfied for 4 hands and satisfied for the remaining hand. Conclusions: Corticoplasty for Ollier disease resulted in cosmetic improvement without functional deterioration. Type of study/level of evidence: Therapeutic IV.
