Guided growth- best treatment for early stage of Blount disease, Study says

The following results were seen-

a. Socio-demographic characteristics were similar for the two groups.

b. Median age at surgery was 6.5 ± 2.5 [3–9 years] in group 1 and 6.8 ± 2.9 years [3–9 years].

c. At a follow-up of 24 ± 3.5 months, the limb alignment was significantly corrected (1,03°/month) in group 1 (median HKA 144°–171°; p = 0,001; median MMPTA 78°–87°, p = 0,018), and in group 2 we observed at a follow-up of 23 ± 15 months a progressive loss (0,52°/month) of the correction obtained immediately postoperatively (median HKA 160°–176°(immediate post operative) to 165,5°; p = 0,31; median MMPTA = 78°–86° (immediate post operative) to 80,5°; p = 0,37).

d. There was a statistically significant difference between the mean variation in HKA between the two groups (group 1 = 22,5; group 2 = 4,5, p = 0.00), as well as for MMPTA; (group 1 = 7; group 2 = 2,5, p = 0,023).

e. The rate of correction was 78% in group 1 with no rebound at a median follow-up after removal of the material of 10 ± 2.4 months.

f. Within group 2, the rate of correction was 10% with a recurrence rate of 60%.

Hence, the authors concluded that "guided growth appears to be the best treatment for early stage of Blount disease (BD)
