Gluteal implants

BACKGROUND: Significant differences exist between feminine and masculine lower extremities, and this region contributes to gender dysphoria in transgender and nonbinary individuals. METHODS: A systematic review was conducted for primary literature on lower extremity (LE) gender affirmation techniques as well as anthropometric differences between male and female lower extremities, which could guide surgical planning. Multiple databases were searched for articles before June 2, 2021 using Medical Subject Headings...

INTRODUCTION: A left ventricular assistance device (LVAD) is indicated in patients with end-stage heart failure. Due to the non-physiologic blood flow, a LVAD may favor pressure sores with a devastating risk of infection. This work shows the prevalence and treatment of pressure sores in LVAD patients, to optimize their management. MATERIAL AND METHODS: We retrospectively investigated all LVAD implantations at the Lausanne University Hospital (CHUV) from 2015 to 2019...

OBJECTIVES: To describe characteristics of women with aesthetically ideal buttocks and differentiate them from women with normal buttocks. METHODS: Case-control study comparing anatomy of women with ideal buttocks (buttocks models) to women with normal buttocks using magnetic resonance images, anthropometric measurements and photography. RESULTS: Comparing to normal women, buttocks models have a narrower waist, narrower iliac crest, wider C point, wider hips and bigger and thicker gluteus maximus muscle (GMM)...

BACKGROUND: Accurate restoration of leg length and proximal femoral geometry is essential for achieving satisfactory outcomes in both primary and revision total hip arthroplasty. Although common landmarks such as the greater trochanter and the lesser trochanter (LT) may be used to measure limb length intraoperatively in primary cases, these landmarks may be absent or disrupted in fractures and revision procedures. We propose the distance between the gluteus maximus tendon gluteal sling (GS) and the center of the femoral head (FHC) as a novel anatomic landmark beyond the zone of injury, which can be used to restore limb length in the setting of proximal femoral bone loss or fracture...

Silicone implants have been used for cosmetic enhancement and reconstructive purposes for over 60 years. Despite assiduous efforts to ensure safety, there is continuous evidence that they are not as biologically inert as previously postulated. We present two cases of autoimmune syndrome induced by adjuvants (ASIA) in Hispanic women. The first patient developed biopsy-proven immune-mediated necrotizing myopathy that was successfully treated with the combination of silicone explantation along with immunosuppressive therapy...

BACKGROUND: The goal was to determine the effect of addition of oblique trajectory distal interlock screws to a retrograde intramedullary femoral nail on implant stability (stiffness), cycles to failure and mode of failure. The hypothesis was that addition of oblique screws would increase implant stability and number of loading cycles to failure. METHODS: Eight matched pairs were tested; one femur implanted with a femoral nail with only transverse distal interlock screws and the other with transverse and oblique interlock screws...

INTRODUCTION: The insertion of gluteal silicone implants by intramuscular technique leads patients to develop gluteus maximus muscle atrophy. The objective of the present study was to correlate the muscular atrophy of the gluteus maximus proportional to the volume of the silicone implants used. The secondary objectives were to assess volumetry of the gluteus maximus muscle in the late follow-up, positioning of the implants and to verify association between volumetric muscle recovery and practice of physical exercise...

OBJECTIVES: It is estimated that 3.8% to 12.5% of patients develop a device infection during the two to four weeks of the sacral neuromodulation (SNM) test, leading to removal of the entire system. It is possible to prolong the test phase up to the clinician's decision, particularly when benefits are unclear. The aim of our study is to assess the device infection rate in a prolonged SNM test. MATERIALS AND METHODS: We retrospectively enrolled patients who performed a prolonged SNM test (at least eight weeks) in the last five years (2017-2021)...

BACKGROUND: Fat grafting is the favored option for buttock augmentation by most surgeons and buttock implants are mostly regarded second choice. Accepted options for buttock implant pocket dissection are subfascial, intramuscular and submuscular. To overcome the limitations of both intramuscular and submuscular pockets, and combine the benefits that both of them have, we present a novel dual-plane pocket dissection. The dual plane pocket means a submuscular plane in the cranial half of the pocket and switching to an intramuscular plane in the caudal half...

Nontuberculous mycobacterial hardware infections are extremely challenging to treat. Multidisciplinary care involving removal of infected hardware, thorough debridement, and durable soft tissue coverage in conjunction with antibiotic therapy is essential for successful management. This case report presents a patient with chronic mycobacterial spinal hardware infection that underwent successful treatment with aggressive serial debridements and reconstruction with a large pedicled superior gluteal artery perforator flap coverage...

INTRODUCTION: Saddle nose deformities are typically reconstructed with cartilage grafts; however, conchal cartilage grafts are and associated with a risk of damage to the posterior auricular ligament and insufficient amounts, and costal cartilage grafts require invasive surgery under general anesthesia. We proposed a double-layer dermofat graft as an alternative to these methods. PATIENT CONCERNS: Two patients with type IV saddle nose deformity underwent reconstruction with nasal augmentation with a double-layer dermofat graft harvested from the gluteal sulcus...

An 87-year-old man presented with malaise, anorexia and postprandial vomiting for 3 days. At presentation the patient was hypotensive and tachycardic, without any other relevant findings. Laboratory workout showed a normocytic normochromic anemia of 4.9g/dl. No hematic losses from the gastrointestinal tract were described or seen. The patient underwent a colonoscopy to study the anemia and an 18mm semi-pedunculated polyp in the descendent colon was found and excised. A whole-body tomography performed during hospitalization showed multiple nodular lesions in the lungs, pleura, peritoneum and left gluteal muscle compatible with metastatic disease...

Continuous accurate attainment of the body temperature of foals is important to detect early stages of severe heat stress or fever due to a systemic illness. Among a number of methods to measure body temperature, measuring rectal temperature with a digital thermometer is most frequently used due to being relatively fast and simple method. It is also comparatively accurate and correlates well with the core body temperature. However, this method requires restraining the foal for a few seconds to obtain the temperature, and it can be dangerous for the handling person...

Buttock augmentation is a commonly performed aesthetic surgery. Several methods have been described, but only the use of implants or autologous fat is consensually deemed safe and effective. Synthetic fillers in gluteal augmentation have been described despite potential severe long-term complications, both medical and aesthetic. The aim of this study is to report a series of 2 consecutive cases who underwent buttock and hip augmentation with large volumes of permanent copolyamide filler requiring surgical removal due to significant complications...

Pelvic chondrosarcomas are a major clinical challenge since the only therapeutic approach available is surgical resection. Reconstruction after partial resection of the pelvis including the acetabulum or the hip joint is a laborious and rigorous surgical procedure. Numerous complications are associated with different reparative methods. Moreover, due to the anatomical complexities of the area, adequate surgical margins are difficult to achieve in many cases, which are closely related to the advent of local recurrence of the tumor...

BACKGROUND: Anatomical custom-made prostheses make it possible to reconstruct complicated bone defects following excision of bone tumors, thanks to 3D-printed technology. To date, clinical measures have been used to report clinical-functional outcome and provide evidence for the effectiveness of this new surgical approach. However, there are no studies that quantified the achievable recovery during common activities by using instrumental clinical-functional evaluation in these patients...

OF BACKGROUND DATA: Pedicle screws are commonly placed with lumbar/lumbosacral fusions. Triggered electromyography (tEMG), which employs application of electrical current between the screw and a complementary anode to determine thresholds of conduction, may be utilized to confirm safe placement of such implants. While previous research has established clinical thresholds associated with safe screw placement, there is variability in clinical practice of anode placement which could lead to unreliable measurements...

INTRODUCTION: Total hip arthroplasty (THA) on a minimally invasive anterolateral (MIAL) approach frequently leads to gluteus minimus and gluteus medius lesions, and sometimes to tensor fasciae latae (TFL) denervation. We therefore developed compensatory strategies, which we assessed on pre- and post-operative MRI: 1) to assess gluteus minimus and gluteus medius fatty infiltration (FI), 2) to assess TFL FI, and 3) to assess FI in the other periarticular muscles. HYPOTHESIS: The modified MIAL approach reduces the rate of gluteus minimus and gluteus medius lesion...

OBJECTIVE: Acetabular revision arthroplasty and osseous defect management through the direct anterior approach (DAA) with or without proximal extension. INDICATIONS: Aseptic or septic component loosening, periacetabular osseous defects, pelvic discontinuity, intrapelvic cup protrusion, anterior pseudotumors, iliopsoas tendonitis, polyethylene wear or iliopsoas abscess. CONTRAINDICATIONS: Clinically relevant gluteal tendon lesions, active infection, morbid obesity, large abdominal pannus, ASA (American Society of Anesthesiologists) score > III, inguinal skin infection...

BACKGROUND: Sacral neuromodulation (SNM) is a common treatment for patients with urinary and faecal incontinence. A close contact of the tined lead electrode with the targeted nerve is likely to improve functional outcome. The aim of this study was to compare the position of the SNM lead in relation to the sacral nerve by comparing different implantation techniques. METHODS: This cadaver study was conducted at the Division of Anatomy of Vienna's Medical University in October 2020...
