Purpose : Adolescent tibia vara is a multiplanar
deformity that can lead to progressive deformity,
altered gait, unequal leg lengths, and premature knee
arthritis if uncorrected. The purpose of the current
study is to report our experience in management of
adolescent tibia vara using Taylor Spatial Frame
(TSF).
Materials and Methods : A prospective study of eleven
adolescent tibia vara patients managed by proximal
tibial osteotomy gradual deformity correction using
TSF.
Results : The average time in the frame was 123.5
(±25.5) days. At final follow up (average 15 (±2)
months), the mean post-operative mPTA was 87 (±4)
degrees (range 81 to 93 degrees), where the mean
preoperative mean mPTA was 68 (±9) degrees (range
49 to 77 degrees) (p value 0.003).
The mean postoperative MAD was 12.2(±11.4) mm,
range (-1 to 26 mm), where preoperative mean MAD
was 75.7(±14.7 mm), range (60 to 107mm) (p value
0.003).
The mean postoperative PPTA was 80(±2) degrees,
range (77 to 83 degrees), while the preoperative mean
PPTA was 72 (±12) degrees, range (42 to 82 degrees)
(p value 0.028).
Conclusion : Although we have not directly compared
the TSF with the Ilizarov fixator, this series serves to
highlight the versatility and effectiveness of the TSF
in the treatment of complex and often obstinate adolescent
tibia vara. |
