Corrective Dome Osteotomy for Cubitus Varus and Valgus Deformity / 대한정형외과학회잡지

ABSTRACT

Purpose: To examine the clinical results of a corrective dome osteotomy for a cubitus varus and valgus deformity. Materials and Methods: Between January 1998 and April 2005, nineteen patients with a cubitus varus or valgus deformity were treated with a corrective dome osteotomy. The mean age of the patients was 29.5 years and the mean follow-up period was 39 months (range, 15 to 95 months). A dome osteotomy was performed along the circle centered approximately 1 cm distally from the olecrenon tip. Internal fixation was performed with multiple K-wires or plates. Results: Bony union was achieved in 18 cases. In the cubitus varus group, the carrying angle was corrected from a mean varus of 17.9o to a mean valgus of 5.9o. The lateral prominence angle (LPI) was corrected from a mean of 15.6% to a mean of -7.6%. In the cubitus valgus group, the carrying angle was corrected from a mean valgus of 36o to 6.7o. The LPI was corrected from a mean -31% to -1.3%. On the functional assessment, 12, 5 and 2 cases showed excellent, good and fair outcomes, respectively. Conclusion: Corrective dome osteotomy for a cubitus varus or valgus deformity is an excellent cosmetic procedure through which a correctional angle can be achieved easily without shortening the humeral length.
