Hip Pain
Published in Benjamin Apichai, Chinese Medicine for Lower Body Pain, 2021
This muscle is important in lower body movement because it stabilizes the hip joint by steadying the head of the femur inside the acetabulum of the hip bone6 and lifts and rotates the thigh away from the body by contributing to the retroversion and external rotation of the hip joint, in addition to abduction of the thigh while in the flexed position.7 This means that as the muscle works, it helps to turn the foot and leg outward.8
Prevention of osteoporosis with estrogen and its analogs: what is new?
Published in Barry G. Wren, Progress in the Management of the Menopause, 2020
With regard to bone, there have been several randomized studies addressing the effectiveness of continued combined therapy in bone protection, particularly at the spine4,5. In general, it would seem that bone loss at the distal radius and the lumbar spine is successfully arrested by this regimen, both in women with low bone mass and in those with established osteoporosis. Long-term data on hip bone density and a fracture risk are awaited.

The hip joint is formed between the femur and the hip bone of the pelvis. The hip bone consists of the ilium, ischium, and pubis, which are fused. Both hip bones, along with the sacrum and coccyx of the spine, form the pelvis. Therefore, the hip joint is the link between the pelvis in the torso and the thigh in the lower extremity. The femur is held firmly in place by strong ligaments and the joint capsule. The hip is a ball and socket joint (see joints), with the head of the femur fitting into the acetabulum of the hip bone, and is the most mobile joint of the lower extremity. Movements at the hip are sagittal plane flexion-extension, frontal plane abduction-adduction, and transverse plane internal-external rotation (see planes and axes of movement).

Therefore, in future research, bones will be regarded as a composite body composed of multiple materials, and the hip bone and femoral body mesh will be divided into multiple material properties according to the elastic modulus and density, instead of the single material property of the material and the simple divided into compact bone and cancellous bone; Further obtain MRI images of the hip joint, and continue to improve the finite element model of the hip joint, such as the construction of muscle solid models and ligament models to make the finite element model of the hip joint closer to reality, but the solid modeling of muscles is a complicated process, for multisample finite element simulation, the use of 1D elements is a means of rapid simulation. Finally, more images of fracture cases should be obtained from clinical cases, so as to realize the finite element analysis of different fracture shapes and fracture types, and further improve, supplement, and verify the results of this article.
Sex differences in bone mineral content and bone geometry accrual: a review of the Paediatric Bone Mineral Accural Study (1991–2017)

Geometric properties from DXA scans were derived using the hip structural analysis (HSA) program (Beck et al. 1990). HSA is described in detail elsewhere (Forwood et al. 2004). In brief, the principle used in the HSA program is that a line of pixel values traversing the bone axis in a DXA image is in effect a projection of the corresponding bone cross-section area (Forwood et al. 2004). The HSA program locates regions on the hip bone mineral image (the narrow neck (NN), the intertrochanter (IT) and the shaft (S); IT scans were removed if the IT region encompassed the growth plate of the greater trochanter) and derives geometric estimates including (i) cross-sectional area (CSA), (ii) superiosteal width (SPW) and (iii) section modulus (Z – an indicator of bending strength). The short-term precision, assessed in healthy adult volunteers, for CSA and Z derived from a hip scan using a Hologic QDR 2000, ranged from 2.2% to 2.3%, 2.3% to 2.8% and 2.8% to 3.4% for the NN, IT and S, respectively (Khoo et al. 2005).
Hip bone marrow edema presenting as low back pain: a case report

At the third physiotherapy visit after 10 days, the patient complained of a worsening of the hip pain at rest (NPRS 3/10) and during his work duties (NPRS 8/10) (Figure 2). Moreover, the patient also described episodes of pain in the lumbar region concurrent with worsening hip pain. This worsen of symptoms may have resulted from an extra-load permitted by the temporary partial decrease of the pain level due to the previous treatment sessions. The X-ray of the pelvis revealed degenerative changes of the acetabular roof and a bilateral osteophytosis of the cotyloid notch. Moreover, on the right side, partial degenerative changes of the femoral head-neck junction were noticed, confirming a CAM type FAI (Figure 3 and Table 1). Given the irritability and quick worsening of the symptoms related to the increased load, the rehabilitation program was stopped and further evaluation was required using specific tests such as the Patellar Pubic Percussion Test (Borgerding, Kikillus, and Boissonnault, 2007; Maselli, Giovannico, Cataldi, and Testa, 2014; Tiru, Goh, and Low, 2002), Percussion Test (Rahman et al., 2013), 128 Hz Tuning Fork Test (Jawad, Odumala, and Jones, 2012; Segat, Casonato, Margelli, and Pillon, 2016), and Single Leg Hop Test (Livingston, Deprey, and Hensley, 2015), which were all positive (Table 2). These tests increased concerns of a specific hip bone disease.
