Abstract: BACKGROUND: There are some differences in acetabular anatomical parameters among different regions and different populations, which are very important for the diagnosis and treatment of acetabular diseases. However, the characteristics of acetabular imaging parameters in the Guizhou population are still unclear.
OBJECTIVE: To analyze the imaging parameters of acetabular plain radiographs, so as to provide a reference for the diagnosis and treatment of acetabular diseases and the design and installment of the acetabular prosthesis.
METHODS: Adult patients who underwent anteroposterior radiography of both hip joints at the Affiliated Hospital of Guizhou Medical University from January 2015 to February 2017 were collected. The acetabular radiographic parameters were measured using the medical imaging software SIEMENS Syngo.Plaza PACS. The data were grouped and analyzed according to age, sex and left and right sides. Pearson correlation analysis was performed between acetabular parameters. The data in the current study were compared with domestic and foreign studies containing the same type of data.
RESULTS AND CONCLUSION: (1) Sharpe angle, center edge angle, anteversion angle, abduction angle, acetabular depth, acetabular diameter, modified acetabular index, and acetabular head index were (39.70±3.65)°, (31.10±6.03)°, (19.17±4.26)°, (39.71±3.67)°, (1.16±0.22) cm, (6.45±0.52) cm, (0.33±0.03), and (84.72±4.19)%, respectively. (2) There were statistical differences in Sharp angle between males and females at different age groups (P < 0.05); statistical differences in abduction angle were found in males among different age groups (P < 0.05). (3) There were differences in Sharp angle, center edge angle, anteversion angle, abduction angle, acetabular depth and acetabular diameter between genders. Sharp angle, anteversion angle and abduction angle were smaller in males than those in females (P < 0.05). The center edge angle, acetabular depth, and acetabular diameter were greater in males than that in females (P < 0.05). (4) There were no significant differences in acetabular parameters between the sides. (5) There were differences in the acetabular imaging parameters of the population in the Guizhou district when compared with the same type of data from domestic and foreign studies. Taken together, the acetabular imaging parameters of the population in Guizhou have certain characteristics. The regional features of acetabular imaging parameters should be fully considered in the clinical diagnosis and treatment of acetabular diseases to achieve greater clinical benefits.
