AIM: To determine the anatomical organization and somatic axonal components of the lumbosacral nerves in female rabbits. METHODS: Chinchilla adult anesthetized female rabbits were used. Anatomical, electrophysiological, and histological studies were performed. RESULTS: L7, S1, and some fibers from S2 and S3 form the lumbosacral trunk, which gives origin to the sciatic nerve and innervation to the gluteal region. From S2 to S3 originates the pudendal nerve, whose branches innervates the striated anal and urethra sphincters, as well as the bulbospongiosus, ischiocavernosus, and constrictor vulvae muscles...

RATIONALE: Hidradenitis suppurativa (HS) is a disabling inflammatory disease mainly affecting apocrine glands. Marjolin ulcer (MU) is a term used to describe a rare type of squamous cell carcinoma (SCC) arising within sites of chronic wounds or preexisting scars. Chronic HS may result in a rare type of SCC, MU, which has a poor prognosis due to its high metastatic rate. CONCERNS OF THE PATIENT: Here we reported a 60-year-old male who developed SCC on the right buttock after suffering from HS for 15 years...

BACKGROUND AND AIM: To date, clinically relevant selection criteria have not been established for the use of the gluteal fold flap after oncological vulvoperineal resection. We prospectively assessed the surgical risk factors of this reconstructive technique in a large series. METHODOLOGY: From April of 2000 through December of 2015, 114 gluteal fold flaps were used for vulvoperineal reconstruction after excision of (pre)malignant skin disorders in 75 women. The possible influence of 10 patient-related and 6 procedure-related risk factors on flap-related postoperative complications was statistically analyzed...

PURPOSE: Ultraviolet (UV)-mediated photofunctionalization has earned considerable attention for the enhancement of the biologic capabilities of titanium. The effects of photofunctionalization on bone augmentation and gap closure were examined using titanium implants and mesh in a rat femur model. MATERIALS AND METHODS: An acid-etched titanium implant (4-mm length, 1-mm diameter) was placed in the gluteal tuberosity that resembles a knife-edge-like edentulous ridge...

Surgical drains are commonly used in surgery to reduce post-operative fluid collections. Whilst rare, a retained surgical drain may result in clinical complications and distress to the patient. A retained surgical drain is a potentially avoidable event and surgeons should be aware on how to confirm the presence of a retained surgical drain. We report a rare case of a blood clot masquerading as a retained surgical drain in a patient. The patient is a 55-year-old Malay male who presented with left gluteal necrotizing fasciitis...

BACKGROUND: Chronic pelvic, perineal and gluteal neuralgia is often experienced in a similar way to neuropathic pain, in the territories of four nerves: ilio-inguinal, pudendal, inferior cluneal and posterior gluteal nerves. These pains are often refractory to medical treatment based on the use of systemic molecules with disabling adverse effects and surgical procedure may be necessary. OBJECTIVE: The objective of this study was to evaluate the efficacy and safety of treatment with a high-concentration capsaicin patch in these indications...

Gluteal muscle contracture (GMC), a debilitating disease, exists all over the globe but it is much more prevalent in China. Patients typically present with abduction and external rotation of the hip and are unable to bring both the knees together while squatting. Multiple etiologies have been postulated, the commonest being repeated intramuscular injection into the buttocks. The disease is diagnosed primarily by clinical features but radiological features are necessary for the exclusion of other pathological conditions...

A 51-year-old man presented with elastofibroma (EF) of the gluteal region with a concomitant contralateral lesion. The patient presented with a slow growing mass of the proximal third of the right buttock and had swelling, discomfort in sitting, and right-hip pain during walking for 2 months. On MRI, a soft-tissue mass was noted between the gluteus maximus and the gluteus medius muscle. The mass showed similar signal intensity to the surrounding tissue on T1- and T2-weighted images and with linear hyperintense areas in its internal structure...

PURPOSE: VMAT treatment planning for large pelvic volume irradiation could be suboptimal due to inability of Varian linac to split MLC carriage during VMAT delivery for fields larger than 14.5cm in X direction (direction of leaf motion). We compare the dosimetry between 3 VMAT planning techniques, two 2-arc field techniques and a 3-arc field technique: a) two small in X direction (less than 14.5cm) arc fields, complementing each other to cover the whole lateral extent of target during gantry rotation, b) two large arc fields, each covering the targets completely during the rotation, c) a 3 field technique with 2 small in X direction arcs and 1 large field covering whole target...

PURPOSE: To review the records of 363 patients with severe gluteal muscle contracture to determine its mechanism, underlying pathology, and treatment outcome. METHODS: Records of 136 males and 227 females aged 5 to 18 (mean, 12.2) years who underwent Z-plasty for bilateral (n=347) or unilateral (n=16) severe gluteal muscle contracture were reviewed. Severe gluteal muscle contracture was classified as typical (n=52) or special (n=311). The typical type is associated with symptoms of positive out-toe gait, Ober sign, back-extending test, cross-leg test, squatting with knee side-by-side test, and hip dysfunction...

BACKGROUND Squamous cell carcinoma (SCC), also known as Marjolin ulcer, is a rare complication of hidradenitis suppurativa (HS). Metastatic SCC from HS typically involves the axial skeleton or abdominopelvic viscera. Metastatic disease to the lungs is a rare phenomenon with only three reported cases of lung parenchyma. We present a biopsy proven case of metastatic SCC to the pleura from gluteal HS. CASE REPORT A 46-year-old male with a history of recently diagnosed Marjolin ulcer secondary to gluteal HS was transferred to our intensive care unit for acute hypoxemic respiratory failure secondary to recurrent pleural effusion...

BACKGROUND: Locoregional flaps are sufficient in most sacral reconstructions. However, large sacral defects due to malignancy necessitate a different reconstructive approach, with local flaps compromised by radiation and regional flaps inadequate for broad surface areas or substantial volume obliteration. In this report, we present our experience using free muscle transfer for volumetric reconstruction, in such cases, and demonstrate three-dimensional (3D) haptic models of the sacral defect to aid preoperative planning...

There are a large number of different approaches to the hip joint. Several conventional and minimally invasive portals exist and numerous technical variations with different instrument sets are available. All approaches can be regarded as standard and can be utilized lege artis. The main differences between approaches are their potential to preserve muscles and avoid damage which would slow down rehabilitation and mobilization. In the elderly the preservation of abductor function is, in the authors' opinion, of utmost importance...

BACKGROUND: Obesity is a public health epidemic and an important breast cancer risk factor. The relationship between interrelated body measurements is complex and most studies fail to account for this complexity. We identified key aspects of body size which jointly, over the life-course (since adolescence), are associated with estrogen-receptor-positive (ER+) breast cancer risk. METHODS: Among 109,862 women participating in the California Teachers Study cohort, 3844 were diagnosed with invasive ER+ breast cancer between 1997-1998 and December 2011...

Grizzly bears (Ursus arctos horribilis) have evolved remarkable metabolic adaptations including enormous fat accumulation during the active season followed by fasting during hibernation. However, these fluctuations in body mass do not cause the same harmful effects associated with obesity in humans. To better understand these seasonal transitions, we performed insulin and glucose tolerance tests in captive grizzly bears, characterized the annual profiles of circulating adipokines, and tested the anorectic effects of centrally administered leptin at different times of the year...

BACKGROUND: During pelvic and sacral tumor resection, important vessels, such as the inferior gluteal artery underneath the sciatic notch, are easily injured because of their invisibility. We employed a computer-assisted navigation system to preserve the inferior gluteal artery at the sciatic notch with visualization of the inferior gluteal artery at the sciatic notch, thus maintaining blood flow to the gluteus maximus. METHODS: We present the results of seven patients (five men and two women) with a mean age of 64...

Chronic Kidney Disease patients suffer from Mineral and Bone Disorder (CKD-MBD) leading to increased vascular and soft-tissue calcification. The prevalence of soft tissue calcification in dialysis patients is not well described, and most cases describe such calcifications in hemodialysis patients. We describe a case of a massive soft tissue calcification in the right gluteal region in a peritoneal dialysis patient. The patient had severe pain and were disabled. The treatment was converted to an intensive hemodialysis regimen with a minimal calcium load and high dose of cinacalcet...
