We studied the results of corrective osteotomy for varus deformity in 16 patients 17 elbows.
Of these 17 elbows, the varus deformity resulted from supracondylar fracture in 5, diacondylar fracture in 11, and unclear in one.
Follow up results showed that correction of the deformities in all 5 elbows which had resulted from supracondylar fractures was satisfactory. Howeit, of the 11 deformities which resulted from diacondylar fractures, a decrease in their corrected angle was seen in 5 that had been treated under the age of 11 years. I have assuned that this sentence you mean treatment was done on young children, under the age of 11. (Rathe than cess than 11 yies follow-up duoatron)
This suggests that corrective osteomy for varus deformity resulting from diacondylar fracture should be done at the age of 12 or 13 years.
