“…This force acts vertically and symmetrically on both sides of the hip joint. [14,32] When standing on one leg, the hip on that side carries the weight of the head, trunk, upper leg, and lower leg on the other side. This weight is concentrated at the center of gravity and is exerted on the hip as an axial load.…”

Background High contact stresses involving the hip have been shown to increase the risk of developing hip osteoarthritis (OA). Although several risk factors have been identified for OA, a holistic approach to predicting contributed factors towards increased hip contact stresses have not been explored. This study was conducted to comprehensively understand the effects of hip morphometry (HM) and level of physical activity on high hip contact stress as predisposing factors of hip osteoarthritis (OA). Methods The protocol of this systematic review was registered in PROSPERO with registration number CRD42022296638. Full articles that matched our inclusion criteria were selected using PubMed, Web of Science, and Scopus search engines and keywords such as “hip contact stress”, “hip contact force” and/or “hip contact pressure”. Category of factors, experimental design, results of the study, and evidence from each article were analyzed. Results In total 7972 papers were reviewed and resulting 11 papers in hip morphometry group and 21 papers belong to physical activity group. Conclusions Hip morphometry (n = 11) and physical activity (n = 21) have correlation with high hip joint contact stress in various manner. However, the reviewed studies vary in their methods. This finding suggested that this area is not well investigated and warrants future research.

“…During the fourth to sixth week of an embryo's development within the uterus, the cavity begins to form. Precartilaginous patterning appears in the seventh week of pregnancy, and by the eighth week of development, the acetabulum has completed its development in its entirety (3) . When the femoral head is not adequately articulated inside the shallow acetabular cavity, a frequent congenital condition known as hip dislocation results.…”

Background: Surgeon may learn more about the acetabular morphology and make a more accurate diagnosis of hip dysplasia by measuring the acetabular depth ratio. Understanding the intricacy and etiopathogenesis of illnesses like primary osteoarthritis of the hip joint etc. requires a thorough familiarity with the anatomical factors associated with this region. Objective: To evaluate the morphometric analysis of acetabulum and its clinical correlation. Study Design: Observational based study Study Setting: This study was conducted in Department of Anatomy, Sharif Medical and Dental College, Lahore from July 2022 to December 2022. Methodology: Using the teaching collection of the Anatomy Department, researchers examined 160 hip bones from adults with known sex. A set of digital vernier calipers was used to get all the measurements. Each variable was measured twice at separate times, and the mean of the two values was recorded. With no abnormalities in the morphology or moisture content of any of the chosen hip bones were included in the study. Osteoarthritic alterations, traumatic injuries, and skeletal diseases all led to specimen exclusion. SPSS version 20 was used for data analysis. Results: All anatomical parameters of 160 hip bones were calculated in cm in which 76 (47.5%) were males and 84 (52.5%) were females. There was no statistically significant difference between the right and left sides of anatomical parameter (p>0.05). However, there were statically different in between gender. Males had a deeper acetabulum (2.8 cm) than females (2.6 cm). The acetabular diameter was statistically significantly larger in men than in females (p=0.00). The notched width in females was larger (2.75 cm) than in men (1.75 cm), and the capacity was more in males as compared to female. 96.7% of the bones had a pointed front and a lunate-shaped back. The form of the lunate at both the anterior and posterior ends is present in 3.3% of the cases. Conclusion: In conclusion, by comparing male and female 20 to 47 years of age, the current research found statistically highly significant (p<0.05) differences in acetabular depth, diameter, capacity, and notch width. Ninety-three percent of the bones had a pointed front and a lunate-shaped rear. Just 5% of instances don't have the lunate shape at either the anterior or posterior ends. In order for orthopedic surgeons to accurately determine the diameter of the acetabulum during surgical operations, it is required to do a preoperative evaluation of the acetabulum's diameter. Keywords: Acetabulum Diameter, Acetabulum Depth, Acetabulum Width, Acetabulum Capacity

“…Hip abductor muscles play an important role in stabilizing the pelvis during gait, which allows the body to effectively maintain balance and lower limb mobility [ 1 ]. This group of muscles includes the gluteus medius, gluteus minimus, and tensor fasciae latae, but the gluteus medius is the main hip abductor muscle [ 2 , 3 ].…”

Background The hip abductor muscles, primarily the gluteus medius, play an important role in stabilizing the pelvis during gait. Gluteus medius weakness is associated with biomechanical changes and musculoskeletal disorders. Individuals with obesity can have great difficulty maintaining abductor muscular function due to being overweight and possibly experiencing a decrease in muscle mass. However, it is still unclear whether the musculature of person with obesity can compensate for these changes. Therefore, the aim of this study was to compare gluteus medius strength between individuals with obesity and normal-weight individuals using a digital hand-held dynamometer. Methods Twenty-five participants with obesity (BMI > 35 kg/m2) were matched for sex, age, and height with normal-weight individuals. Gluteus medius strength was measured by a single examiner using a belt-stabilized hand-held digital dynamometer placed on the knee of the individuals positioned in lateral decubitus. Three measurements were recorded with rest intervals, and only the highest value measured for each limb was used for analysis. The differences between pairs were calculated, and the normality of the data was assessed using the Shapiro-Wilk test (p < 0.05). The matrices of the variables were standardized and analysed using principal component analysis (PCA). Results For the strength variables (Newtons) on both sides, no significant differences were detected between the groups (p > 0.05). However, significant differences were detected in these variables between the groups (p < 0.05) when the measurements were normalized to body weight (Newtons/kilograms). PCA indicated that both the absolute and normalized values of strength are lower in participants with obesity than in normal-weight. Conclusions These findings suggest that people with obesity could have the same or less strength (PCA) to move more mass, which may imply a relative weakness that induces functional limitations.
