BACKGROUND
Body image research deals a lot with awareness of the body as an entity. Studies that consider individual anatomical aspects and place them in an intercultural context are rarely present.
METHODS
For this purpose, general data, body perception and judgment of body images from 2163 (48% female and 52% male) participants from Germany, Nigeria, the USA and Japan were evaluated as part of a survey.
RESULTS
There were clear differences in the personal body image of the participants' own buttocks, the buttocks as a beauty ideal and the way in which dissatisfaction was dealt with in different countries. In addition to sexual well-being (importance score: 0.405 a.u.), the country of origin (0.353), media consumption (0.042) and one's own weight (0.069) were also identified as influencing factors for satisfaction with one's own buttocks. A clear evolution could be derived regarding a WHR (waist-to-hip ratio) of well below 0.7, which was consistently favored by the participants but also propagated by influencers through images ( < 0.001). In this context, participants who indicated celebrities as role models for the buttocks showed a correspondingly high level of dissatisfaction with their own buttocks (R = -0.207, < 0.001, ρ = -0.218).
CONCLUSION
Overall, a highly significant correlation was shown between the consumption frequency of Instagram, TikTok and pornography with the negative perception of women's own buttocks.

Review
BACKGROUND
Measures of hip muscle morphology and composition (e.g., muscle size and fatty infiltration) are possible with magnetic resonance imaging (MRI). Standardised protocols or guidelines do not exist for evaluation of hip muscle characteristics, hindering reliable and valid inter-study analysis. This scoping review aimed to collate and synthesise MRI methods for measuring lateral hip muscle size and fatty infiltration to inform the future development of standardised protocols.
METHODS
Five electronic databases (Medline, CINAHL, Embase, SportsDISCUS and AMED) were searched. Healthy or musculoskeletal pain populations that used MRI to assess lateral hip muscle size and fatty infiltration were included. Lateral hip muscles of interest included tensor fascia late (TFL), gluteus maximus, gluteus medius, and gluteus minimus. Data on MRI parameters, axial slice location, muscle size and fatty infiltrate measures were collected and analysed. Cross referencing for anatomical locations were made between MRI axial slice and E-12 anatomical plastinate sections.
RESULTS
From 2684 identified publications, 78 studies contributed data on volume (n = 31), cross sectional area (CSA) (n = 24), and fatty infiltration (n = 40). Heterogeneity was observed for MRI parameters and anatomical boundaries scrutinizing hip muscle size and fatty infiltration. Seven single level axial slices were identified that provided consistent CSA measurement, including three for both gluteus maximus and TFL, and four for both gluteus medius and minimus. For assessment of fatty infiltration, six axial slice locations were identified including two for TFL, and four for each of the gluteal muscles.
CONCLUSIONS
Several consistent anatomical levels were identified for single axial MR slice to facilitate muscle size and fatty infiltration muscle measures at the hip, providing the basis for reliable and accurate data synthesis and improvements in the validity of future between studies analyses. This work establishes the platform for standardised methods for the MRI assessment of lateral hip musculature and will aid in the examination of musculoskeletal conditions around the hip joint. Further studies into whole muscle measures are required to further optimise methodological parameters for hip muscle assessment.

Review
We present the particular clinical and histological features of a metastatic high-grade myxofibrosarcoma (MFS) of the left buttock in a 77-year-old male patient. The tumor was biopsied and surgically removed in order to increase the patient's comfort, due to its increased size and aggressive clinical behavior. Computed tomography (CT) revealed metastases in the pleura and mediastinal lymph nodes, so limb-sparing tumor excision followed by palliative care was the best practice for the patient until the fatal outcome. The histological assessment revealed a tumor composed partly of solid sheets of spindled and pleomorphic cells, partly of areas with prominent myxoid matrix and numerous elongated capillaries. Mitotic figures are frequent, often atypical, followed by numerous giant cells with abundant eosinophilic elongated cytoplasm, resembling myoid cells often multinucleated. A panel of immunohistochemical stainings, including muscle-specific actin (MSA), S-100, CD34, desmin and myogenin were performed with a negative result, which aided excluding other soft tissue tumors like rhabdomyosarcoma and leiomyosarcomas, while Ki-67 was highly expressed in more than 70% of the tumor cells. This tumor received 6 points in accordance with the Fédération Nationale des Centres de Lutte Contre le Cancer (modified FNCLCC) and was defined as a high-grade MFS [stage IV, G3 pT2bN0M1, according to the 8th edition of TNM Classification of Malignant Tumors, ICD-O 8811÷3 in World Health Organization (WHO) Classification 2013]. Due to the clinical findings combined with the histological profile, the fatal prognosis was expected, though the time period was shorter than predicted, confirming the aggressive nature of the tumor. Even if traditionally was considered MFS as a non-metastatic lesion, recent case reports and studies, including our case revealed that this tumors in fact have the potential to be fatal due to metastatic disease.

INTRODUCTION
Advances in medical science are helping to break down the barriers to surgery. In the near future, neonatal or in utero operations will become the standard for the treatment of defects in the human motor system. In order to carry out such procedures properly, detailed knowledge of fetal anatomy is necessary. It must be presented in an attractive way not only for anatomists but also for potential clinicians who will use this knowledge in contact with young patients. This work responds to this demand and presents the anatomy of the superior gluteal nerve in human fetuses in an innovative way. The aim of this work is to determine the topography and morphometry of the superior gluteal nerve in the prenatal period. We chose the superior gluteal nerve as the object of our study because of its clinical significance-for the practice of planning and carrying out hip surgery and when performing intramuscular injections.
MATERIAL AND METHODS
The study was carried out on 40 human fetuses (20 females and 20 males) aged from 15 to 29 weeks (total body length v-pl from 130 to 345 mm). Following methods were used: anthropological, preparatory, image acquisition with a digital camera, computer measurement system Scion for Windows 4.0.3.2 Alpha and Image J (accuracy up to 0.01 mm without damaging the unique fetal material) and statistical methods.
RESULTS
The superior gluteal nerve innervates three physiologically significant muscles of the lower limb's girdle: gluteus medius muscle, gluteus minimus muscle and tensor fasciae latae muscle. In this study the width of the main trunk of the nerve supplying each of these three muscles was measured and the position of the nerve after leaving the suprapiriform foramen was observed. A unique typology of the distribution of branches of the examined nerve has been created. The bushy and tree forms were distinguished. There was no correlation between the occurrence of tree and bushy forms with the body side (p > 0.05), but it was shown that the frequency of the occurrence of the bushy form in male fetuses is significantly higher than in female fetuses (p < 0.01). Proportional and symmetrical nerve growth dynamics were confirmed and no statistically significant sexual dimorphism was demonstrated (p > 0.05).
CONCLUSIONS
The anatomy of the superior gluteal nerve during prenatal period has been determined. We have identified two morphological forms of it. We have observed no differences between right and left superior gluteal nerve and no sexual dimorphism. The demonstrated high variability of terminal branches of the examined nerve indicates the risk of neurological complications in the case of too deep intramuscular injections and limits the range of potential surgical interventions in the gluteal region. The above research may be of practical importance, for example for hip surgery.

Review
BACKGROUND
The number of patients undergoing buttock augmentation surgery has increased rapidly with time, changes in people's aesthetic perceptions, and the increased concern for their shape. The number of publications regarding buttock augmentation has also continued to increase. However, no bibliometric analysis concerning buttock augmentation has been published. This study aimed to provide a qualitative and quantitative evaluation of buttock augmentation-related publications using bibliometric analysis and information on research hotspots and trends in this field.
METHODS
The buttock augmentation-related publications published between 1999 and 2021 were extracted from the Web of Science Core Collection (WOSCC) database for analysis. The data were analysed and presented using VOSviewer and Microsoft Excel.
RESULTS
There were 492 articles in the (WOSCC) database, including 442 (89.84%) original research articles, with the number of publications increasing each year. The USA (208 publications, 42.28%) is the leading contributor in this field and has a high academic reputation. The most productive and co-cited journal on this subject is "Plastic and Reconstructive Surgery" (66 publications, 13.41%, 2200 citations). Cardenas-Camarena (9 publications, 1.83%, 158 citations) was the most published and co-cited author. Research hotspots include the following three topics: experience and technology of buttock augmentation, autologous fat buttock augmentation and its safety, and buttock aesthetics study. There will be more publications in the future, and research trends will focus on silicone implants, safety, satisfaction, and autologous fat grafting.
CONCLUSION
Buttock augmentation research is rapidly evolving, and this study provides a perspective view of buttock augmentation research in Plastic and Reconstructive Surgery.

INTRODUCTION
Minimally invasive approaches (direct anterior approach: DAA; minimally invasive anterolateral: MIAL; piriformis-sparing posterior approach: PSPA) are widely used for total hip arthroplasty (THA), with a muscle-sparing objective. There are no published comparative studies of muscle damage secondary to these approaches. The aim of the present study was to compare fatty infiltration (FI) on MRI induced by DAA, MIAL and PSPA in THA 1) in the tensor fasciae latae (TFL) and sartorius muscles, 2) in the gluteal muscles, and 3) in the pelvitrochanteric muscles.
HYPOTHESIS
Greater FI is induced by DAA in anterior muscles, by MIAL in gluteal muscles and by PSPA in pelvitrochanteric muscles.
MATERIALS AND METHODS
Three continuous prospective series of THA by DAA, MIAL and PSPA included 25 patients each. MRI was performed preoperatively and at 1 year postoperatively. FI was graded on the Goutallier classification in all periarticular hip muscles. Muscles showing ≥2 grade aggravation at 1 year were considered damaged.
RESULTS
Nine patients whose preoperative MRI was uninterpretable were excluded. In all, 66 patients (21 DAA, 24 MIAL and 21 PSPA) with 132 MRI scans were analyzed. TFL was damaged in 2/21 DAA patients (9.5%), 1/24 MIAL patients (4.2%) and 0/21 PSPA patients (0%). There were no sartorius lesions. The anterior third of the gluteus medius was damaged in 8/24 MIAL patients (33.3%) and the gluteus minimus in 10/24 (41.7%), compared to 1/21 DAA patients (4.8%) and 0/21 PSPA patients (0%). The mid and posterior thirds of the gluteus medius and the gluteus maximus were never damaged. The piriformis muscle was damaged in 3/21 DAA patients (14.3%), 2/24 MIAL patients (8.3%) and 2/21 PSPA patients (9.5%). The obturator internus was damaged in 4/21 DAA patients (19%), 1/24 MIAL patients (4.2%) and 16/21 PSPA patients (76.2%). The obturator externus and quadratus femoris were mainly damaged in PSPA patients: respectively, 5/21 (23.8%) and 4/21 patients (19%)).
CONCLUSION
The muscle-sparing properties of minimally invasive hip approaches are only theoretical. In the present series, there were rare TFL lesions with DAA and MIAL. Gluteus medius and minimus lesions were frequent in MIAL. Pelvitrochanteric muscles lesions were more frequent in PSPA, but found in all 3 approaches. These findings should help guide surgeons in their choice of approach and in informing patients about the damage these minimally invasive approaches can cause.

Review
RATIONALE
Calcinosis cutis is a rare skin disease, and idiopathic cases are rarely reported. It is characterized by the deposition of insoluble calcium salts in the skin, subcutaneous tissue, superficial muscles, and tendon sheaths. However, no abnormal changes were found in the bone. In this article, we introduce a case of idiopathic calcinosis cutis of the buttocks with a long course and large lesion area.
PATIENT CONCERNS
A 51-year-old male patient was admitted to the hospital with a chief complaint of 'Due to the discovery of hard nodules with pruritus in the buttocks for 32 years. The patient was a male who was 51 years old. He has been in good health and reported no history of surgery, trauma, infection, metabolic disease, tumor, or other diseases. There was no family history. It is worth noting that the patient has the occupation of driving trucks, which keeps him sedentary.
DIAGNOSES
The accurate diagnosis of calcinosis cutis was confirmed by postoperative histopathological examination with many local calcifications and multinucleated giant cells in subcutaneous tissue.
INTERVENTIONS
The patient underwent skin lesion excision and autologous skin grafting under general anesthesia. A medium-thickness skin graft from the left lateral thigh was transplanted into the hip operation area, and a bolus tie-over pressure dressing was applied. After the operation, the patient received anti-infection treatment and was advised to rest in the prone position to prevent extrusion of the operation area.
OUTCOMES
The postoperative recovery was good, and there was no recurrence after 4 months of follow-up.
LESSONS
The incidence rate of cutaneous calcinosis is not clear. This patient had a large lesion area, long onset time, an invasion of the fat layer, and the onset site was located in the sacrococcygeal region. It is necessary to choose appropriate treatment methods.

BACKGROUND AND OBJECTIVE
Magnetic muscle stimulation (MMS) is a relatively new energy-based technology that provides a non-invasive option for body contouring through stimulation and toning of underlying skeletal muscles. This study was conducted to examine the safety, efficacy, and body satisfaction scores of MMS using a CoolToneTM prototype for the aesthetic improvement of abdominal and buttock contour.
STUDY DESIGN/MATERIALS AND METHODS
This was a prospective, non-comparative, non-randomized, 12-week, multicenter study. Male and female participants aged 22-65 years received 4 MMS treatment sessions to the abdomen and/or buttocks. Body Satisfaction Questionnaire (BSQ) scores for abdomen and/or buttocks were assessed at baseline, immediately post final treatment, at 4 weeks (primary endpoint), and 12 weeks post final treatment. Subject-rated Global Aesthetic Improvement Scale (SGAIS) was assessed at 4 weeks post final treatment (secondary endpoint), and 12 weeks post final treatment. Additional efficacy assessment included abdominal circumference obtained by 3D imaging at baseline, immediately post final treatment, and at 4 and 12 weeks post final treatment. A Subject Experience Questionnaire (SEQ) was used to assess treatment satisfaction and perspectives at 4 weeks and 12 weeks post final treatment. Adverse events (AEs) were monitored throughout the study.
RESULTS
A total of 110 participants were recruited, who were 75% female, 80% Caucasian (mostly non-Hispanic), average age of 39.5 years (range 22-59) with an average body mass index (BMI) of 23.3 kg/m2 (range 18-29.9). At the 4-week post final treatment visit, the average BSQ score for participants receiving abdominal treatment (n = 93) was significantly improved with a 5.1 average increase in total score from baseline (possible score range 10-50) and by a 5.5 average increase from baseline for participants receiving buttocks treatment (n = 32) (p < 0.05). At 4 weeks post final treatment, the proportion of participants with SGAIS scores >"Improved" was 68.1% for participants receiving treatment of the abdomen (n = 94), and 81.8% for those receiving buttocks treatment (n = 33). The mean total decrease from baseline in waist circumference was significant at all time points. At the 12-week post final treatment visit, SEQ data revealed that a majority of participants were "Satisfied" or "Very Satisfied" with overall treatment results and "Agreed" or "Strongly Agreed" that they were motivated to maintain results either by working out or by additional treatment. A total of 6 AEs related to the device and/or treatment were reported, which resolved spontaneously during the study.
CONCLUSION
Treatment of the abdomen and/or buttocks with MMS was well-tolerated and demonstrated significant improvement in aesthetic appearance through the 12-week post final treatment study duration. As a stand-alone treatment, MMS expands the range of options for individualized treatment planning for patients seeking abdominal and/or gluteal muscle toning. © 2020 The Authors.
