Background:
Tibial torsion is an important anatomical parameter in clinical practice and displays variability among individuals. These variations are extremely significant in view of alignment guides such as those related to rotational landmarks of tibia in total knee arthroplasty. Further, precise knowledge and information pertaining to angle of tibial torsion also helps in correction of traumatic malunion or congenital maltorsion of tibia.
Methods:
The present study was carried out to determine the angle of tibial torsion in 100 adult dry tibia bones in the Department of Anatomy, Government Medical College, Amritsar. The study group comprised 50 males and 50 females with equal number of right- and left-sided bones. The measurements were meticulously recorded and the data were subjected to statistical analysis. The results were analyzed and discussed in the light of existing literature.
Results:
On the right side, it was found to be 29.84° ± 4.86°° (range = 22.00° -38.00°) in males and 28.92° ± 5.10°° (range = 15.00°-38.00°) in females. On the left side, it was found to be 28.00° ± 4.94°° (range = 20.00°-40.00°°) in males and 28.12° ± 4.28°° (range = 20.00°-37.00°°) in females.
Conclusion:
The present study is an endeavor to provide baseline data with reference to the angle of tibial torsion in the Indian population. The results of the study assume special importance in view of the technical advancements in reconstructive surgical procedures in orthopedic practice.
