ABSTRACT:

Background: The pedicles exhibited significant variability in their shape and orientation, not only from region to region within the thoracic spine, but also within the same region and even within the same pedicle. Morphometric measurements of a spine in the particular geographical area will help in proper implant selection during spinal surgeries, designing of best suited implant, understanding the biomechanics and pathoanatomy of the spine

Methods: In this study sample size was 100 (58 male and 42 female) embalmed and preserved thoracic spine (T1 to T12) aged 35 to 80 years at the time of death.All the linear measurements like Vertical Interpedicular Distance (VIPD), Transverse Interpedicular Distance   (TIPD), Sagital Angle (SA) measured  using digital vernier calipers

Result: PH increased from T2 to T12 vertebral level in male and female subject groups. CL increased from T1 to T12 vertebral level in males and females groups in direct and CT measurement. The PW was higher at upper and lower thoracic level compare to mid thoracic region in males and females. SA showed significant difference (p < 0.05) between males and females in all vertebral levels except T2, T3, T11, and T12.In TIPD there was significant difference (p < 0.05) between  males and females in all the vertebral level as except at T4, T5, T6 it was not significant as p > 0.05. The VIPD was increased from T1 to T12 in males and females.

Conclusion: The results of the present study can help in designing implants and instrumentations, understanding spine pathologies; and management of spinal disorder in this ethnic group with females and males.

Key words: Pedicle, Morphometry, Thoracic Vertebrae.
