Abstract:
Objectives:To research radiographic anatomy of the main structure of the pelvic Teepee view,including its azimuth direction and view anatomy structure. Methods:From June 2013 to June 2014 adult pelvic CT examination results were filtered,excluding skeletal deformities and pelvic osseous destruction caused by tumors,trauma,etc. The data of 2.0 mm contiguous CT scan of 9 adults' intact pelves was selected and input into Mimics 10.01 involving 7 males and 2 females with an average age of(41.2±10.3)years old. Utilizing the software,the 3D CT reconstructions of the pelves were completed. Set?ting the transparency being high,the pelvic 3D reconstructions were manipulated from the pelvic anteroposterior view to the combined obturator oblique outlet view and fine tuned till the regular Teepee or teardrop shaped appearance emerges. Cutting tools of the software were at the moment applied to separate the"Teepee"from the main pelvis for each reconstruction. Then the"Teepee"and the rest(main)part of the pelvis were displayed in different color to facilitate the analysis on the Teepee,ili?ac oblique,and anteroposterior views. Results:The"Teepee"started from the posterolateral aspect of the anterior inferior iliac spine and finished at the cortex between the posterior superior iliac spine and the posterior inferior iliac spine in a direction of being from caudal anterior lateral to cranial posterior medial. The radiographic anatomical composition of the"Teepee"con?tained one tip,one base,and two aspects. With the inner and outer iliac tables being the inner and outer aspects of the"Tee?pee",the tip is consequently formed by their intersection. The base is imaged from the cortex of the greater sciatic notch. The medial inferior posterior portion of the"Teepee"contains a small part of sacroiliac joint and its corresponding side of bone of the sacrum. Conclusions:The"Teepee"is a zone of ample osseous structures of the pelvis,aside from a small medial inferior posterior portion,the main zone of which can be accepted as a safe osseous zone for the anchor of implants stabilizing certain pelvic and acetabular fracture patterns. The Teepee view can be utilized as guidance for the safe percutaneous insertion of such implants.
