“…Although the limitations of 2D measurements in assessing complex three-dimensional (3D) anatomies are well known, they still represent the gold standard in the preoperative planning of hip surgeries due to the lack of adequate 3D measurement methods. Studies have shown that 2D measurements are biased by the projection of the anatomy in the radiographs [16][17][18][19][20][21][22][23] and the intra-and inter-reader variability of the measurement methods [20,[24][25][26]. This underlines the need for a more robust 3D preoperative planning method in order to accurately determine and implement the optimal correction.…”

Augmented reality (AR)-based surgical navigation may offer new possibilities for safe and accurate surgical execution of complex osteotomies. In this study we investigated the feasibility of navigating the periacetabular osteotomy of Ganz (PAO), known as one of the most complex orthopedic interventions, on two cadaveric pelves under realistic operating room conditions. Preoperative planning was conducted on computed tomography (CT)-reconstructed 3D models using an in-house developed software, which allowed creating cutting plane objects for planning of the osteotomies and reorientation of the acetabular fragment. An AR application was developed comprising point-based registration, motion compensation and guidance for osteotomies as well as fragment reorientation. Navigation accuracy was evaluated on CT-reconstructed 3D models, resulting in an error of 10.8 mm for osteotomy starting points and 5.4° for osteotomy directions. The reorientation errors were 6.7°, 7.0° and 0.9° for the x-, y- and z-axis, respectively. Average postoperative error of LCE angle was 4.5°. Our study demonstrated that the AR-based execution of complex osteotomies is feasible. Fragment realignment navigation needs further improvement, although it is more accurate than the state of the art in PAO surgery.

“…The femoral head coverage (FHC) was measured using three vertical lines passing through the medial part of the hip joint space (line I), lateral edge of the acetabulum (line II) and lateral outline of femoral head (line III). The FHC was determined by the formula 13 : (Distance between lines I and II) ÷ (Distance between lines I and III) × 100 ( Fig.2a ).…”

Objectives: To measure acetabular parameters and to compare parameters of acetabulum between men and women, and right and left sides. Methods: The study was conducted in PNS Shifa Hospital, Karachi from January to June 2021. Anteroposterior radiographs of both hips of 70 adults aged 20-70 years were included. The study consisted of 35 men and an equal number of women. We measured acetabular depth, femoral head coverage, acetabular inclination and acetabular depth and width. The acetabular depth was measured using Wiberg’s central edge (CE) angle and Sharp angle techniques. Femoral head coverage was determined using measurements between medial edge of hip joint space, lateral edge of acetabulum and femoral head. To determine acetabular inclination, Tönnis angle was measured. Acetabular depth & width ratio (ADR) was evaluated by dividing acetabular width by depth, and multiplying by 100. Results: There was significant increase in Sharp angle and Tonnis angle in females on the left side as compared to males. Wiberg’s central edge angle and acetabular width to depth ratio showed insignificant increase in males as compared to females, whereas values of femoral head coverage were insignificantly more in women. Conclusion: The acetabular parameters were insignificantly different in gender and between right and left sides, although mean values were within normal range. The larger ADR ratio in men was most likely due to increased body weight in them as compared to women. doi: https://doi.org/10.12669/pjms.38.8.5915 How to cite this:Khaliq S, Qamar A, Khokhar SK, Naseer H.

“…A deformidade da coxa vara, tem como uma das consequências a redução do comprimento em repouso dos músculos abdutores da coxa, por conseguinte, se traduz clinicamente com redução da força desse grupamento muscular, e que pode causar a marcha de Trendelenburg, caracterizada por uma tendência de queda para o lado oposto durante a fase de apoio, marcha típica de pacientes com disfunção dos músculos abdutores, principalmente do glúteo médio, no qual tem a maior função abdutora (Popat et al, 2020).…”

The coxa valga and coxa vara are considered morphological alterations determined by a change in the colodiaphyseal angle, which is the angulation between the femoral neck and the femoral shaft. In a normal adult individual, this angle varies between 120° and 135°, however, when there is an angle smaller than 120°, it is called “coxa vara”, and in the case of an angulation, greater than 135°, it is called “coxa valga”. And these changes can generate impacts to the locomotor system that affect the quality of life of individuals with these deformities. Therefore, this study aims to highlight the main functional impairments of the skeletal, muscular and joint systems caused by coxa valga and coxa vara. Articles were collected in the MEDLINE and BVS databases, with the descriptors (“coxa valga” OR “coxa vara”), during the month of September 2022. Subsequently, the selected material was carefully analyzed in order to gather the most relevant information on the topic proposed. Eleven articles were included in the review, with the main results found in the articles placed in a prism flowchart as a form of summary. Therefore, through this review, there are numerous unfavorable consequences for the locomotor system that the presence of coxa valga and coxa vara entail for the lives of affected individuals.
