“…In our study, the average size of the acetabulum was 50.22 ± 3.5 mm, which is similar to the study by Tran Trung Dung (2019) of 50 ± 2.9 mm, both on a group of mature Vietnamese individuals. 4 The depth of the acetabulum and acetabular depth ratio in our study were 18 Baharuddin's study (2018) 6 of Malaysians, Paul's study 7 of Indians, and Arsic's study 8 of Serbians, in which no statistically significant difference was found in acetabular depth and index. The average size of the femoral head in our study was 43.54 ± 3.68 mm, which was not statistically different from Tran Trung Dung's study (2019).…”

Background The anatomical parameters of the acetabulum vary among races and geographical regions. Multislice Computed Tomography (CT) has proven to be a practical approach to assess morphological parameters of the acetabulum. The purpose of this study was to explore morphological characteristics of the acetabulum measured by CT scans in Vietnamese adults. Methods Thirty-five consecutive patients aged 18 years and older received indications and eligibility for total hip replacement surgery. Sixty-three acetabulum were examined with multislice computed tomographic system (CT) with multiplanar reconstruction (MPR). Measured morphometric parameters of acetabulum included acetabular inclination angle (AIA), acetabular anteversion angle (AAA), acetabular angle of sharp (AAS), sagittal acetabular angle (SAA), acetabular horizontal offset (AHO), transverse acetabular ligament anteversion (TALA), transverse acetabular ligament inclination (TALI), acetabular depth (ADe), acetabular depth ratio (ADr) and acetabular diameter (ADi). Results The mean values of acetabular diameter, femoral head diameter, AIA, AAA, AAS, SAA, TALA, TALI, AHO, ADe, ADr were 50.22±3.56 mm, 43.54±3.68 mm, 40.27±5.09 mm, 13.30±5.54 mm, 39.46±5.41 mm, 26.38±9.01 mm, 9.49±3.92 mm, 47.70±6.73 mm, 3.06±0.37 mm, 18.62±2.95 mm and 309.60±41.87 mm. Conclusion Our initial data has showed morphological characteristics of the acetabulum in Vietnamese adults, different from the populations from other parts of world. Also, significant correlation between the orientation of the acetabulum and the transverse acetabular ligament was documented.

“…In the current study, a significant difference was determined between the right and left sides in the AAA parametric measurements ( P = .007) (Table 4 ). Paul et al [ 15 ] reported that in a Northern Indian population there was no difference between the sides or the genders in respect of the anteversion measurements. Three-dimensional evaluation of the acetabular morphology is important to be able to plan the angle and depth of cup placement in THA applications.…”

“…[12] In literature there are many CT-based studies about acetabular morphology that have been conducted on different ethnicities. [11,[13][14][15][16][17][18][19] The common points of these studies is that they have presented different characteristics of acetabulum anatomy between different populations and between individuals. There are also publications which have been conducted on acetabular medial wall thickness for the CT-based evaluation of acetabular bone stock.…”

Determination of the acetabular morphology and orientation is important for the total hip arthroplasty applications. In general, preoperative planning for these patients is done on true hip X-rays in orthopedics clinics. But those evaluations may not represent the acetabular architecture in detail, because of 2 dimensional images. The aim of this study is to determine the acetabular morphology of a healthy Turkish adult population sample through examination of acetabular parameters on 3-dimensional computed tomography (CT)-based images according to side and gender. A retrospective evaluation was made of acetabulum CT scans taken for various reasons in a healthy Turkish population sample. The examination parameters were defined as measurements of the acetabular anteversion angle, acetabular abduction angle, lateral center edge angle, acetabular width, acetabular depth, sagittal acetabular angle, and medial wall thickness values. The CT scans including the bone structure were examined of a total of 252 hips of 126 patients. The acetabular index was calculated as depth/width × 100. Lateral center edge angle of < 20° with medial wall thickness > 5 mm was accepted as a criterion of dysplasia of the acetabulum. Evaluation was made of the acetabular CT scans of 73 females and 53 males with a mean age of 44.64 ± 12.31 (19–68) years. A statistically significant difference was determined between the sides in respect of acetabular anteversion angle (P = .007) and between the genders in respect of acetabular depth and acetabular width (P = .001, P = .001). The prevalence of dysplasia was determined to be 1.6% for the whole study group, as 1.9% in males and 1.4% in females. In the current study sample there were parametric differences between sides and genders in terms of acetabulum morphology and orientation. Further studies of larger series will be able to provide a better representation of the Turkish population.

Introduction. The most effective method of treatment of patients with severe forms of coxarthrosis is endoprosthetics, the success of which directly depends on the correctness of preoperative planning based on knowledge of the morphology of the acetabulum in normal and pathological conditions. The aim of the investigation was to reveal the morphological features of the acetabulum in osteoarthritis of the hip joint, determining the technology of implant bed preparation for the prosthesis cup. Materials and methods. The study was conducted on 19 macerated pelvic preparations and 72 direct projection pelvic radiographs in 72 patients with stage III osteoarthritis of different etiology aged from 41 to 70 years (61.5 ± 1.4). Hyperplastic coxarthrosis was observed in 21 (29.2%), protrusion in 23 (31.9%), and dysplastic in 28 (38.9%) cases. Clinical, radiological, morphometric, and statistical methods of investigation were used. Methods of descriptive statistics were used. Results. The following data were obtained during morphometric studies: In hyperplastic coxarthrosis, the bottom thickness was 11.9±1.83 mm with an acetabular index (IVI) of 0.51±0.019; in protrusion coxarthrosis, the bottom thickness was significantly reduced and was 5.7 ± 0.93 mm, IVI of 0.66 ± 0.039; in dysplastic coxarthrosis, the bottom thickness was 14.5 ± 1.18 mm, IVI 0.42 ± 0.024 respectively. Discussion. Studies on acetabulum morphometry are being conducted worldwide; among residents of different countries, data on the depth of the acetabulum differ, the morphometric data obtained by us are relevant in terms of the variational anatomy of the population of the Ural region. The morphological features of acetabulum affect the technology of preparing the implant bed for the prosthesis cup, so the preoperative design of implantation is relevant. The proposed method of finding the center of rotation of the deformed acetabulum makes it possible to determine the required thickness of augments to compensate for bone defects in the area of the acetabulum floor and arch. Conclusions. The morphological features of the acetabulum in hyperplastic, dysplastic, and protrusion coxarthrosis determine the technology of implant bed preparation for a prosthetic cup.
