BACKGROUND: Bertolotti's syndrome is a spinal disorder characterized by abnormal enlargement of the transverse process of the most caudal lumbar vertebra. The L5 transverse process may be enlarged either unilaterally or bilaterally and may articulate or fuse with the sacrum or ilium. Pseudoarticulation between the transverse process of the L5 and the alar of the sacrum can cause buttock pain and leg pain. In addition, the L4 exiting nerve root could be compressed by an enlarged L5 transverse process...

BACKGROUND: Sacrum is a triangular bone placed in the base of the spine and formed by the synostosis of five sacral vertebrae (S1-S5). Its upper part is connected with the inferior surface of the body of L5 vertebra forming the lumbosacral joint, while its lower part is connected with the base of the coccyx forming the sacrococcygeal symphysis, an amphiarthrodial joint. The existence of four pairs of sacral foramen in both anterior and posterior surface of the sacrum is the most common anatomy...

A monolateral sacrum fracture was primarily diagnosed with a CT and treated with PMMA augmented SI screw fixation. The following CT showed an unexpected contralateral fracture which led to the need for a lumbopelvic stabilization. In the course of 6 months, successively occurring adjacent fractures required recurrent vertebroplasty. Most of these fractures could only be diagnosed through MRI. It remains unclear, whether initially even the contralateral sacral ala was fractured.

INTRODUCTION: Kyphosis is a frequent problem in children with spina bifida, and this deformity may cause different complications as respiratory insufficiency, bowel dysfunction, and skin ulcers. CASE REPORT: We report on a 13-year-old myelomeningocele male with a lumbar kyphoscoliosis associated to a septic skin ulceration that resulted in an acute sepsis. An X-ray revealed a kyphosis of 110° and a scoliosis of 25° between T9 and L5. The wound and blood cultures showed Staphylococcus aureus colonization, and an appropriate antibiotic therapy was started...

Giant cell tumor (GCT) of bone is a locally aggressive benign neoplasm that is associated with a large biological spectrum ranging from latent benign to highly recurrent and occasionally metastatic malignant bone tumor. It accounts for 4-10% of all bone tumors and typically affects the meta-epiphyseal region of long bones of young adults. The most common site involved is the distal femur, followed by the distal radius, sacrum, and proximal humerus. Clinical symptoms are nonspecific and may include local pain, swelling, and limited range of motion of the adjacent joint...

The caudal regression syndrome is defined as total or partial agenesis of the sacrum and lumbar spine, frequently associated with other developmental malformations (orthopedic, neurological, genito-urinary, gastrointestinal…). Prenatal diagnosis is possible through fetal ultrasound (US) and magnetic resonance imaging (MRI). A case of fetal caudal regression syndrome with omphalocele from a diabetic mother is presented, demonstrating the sonographic, MRI, CT and X-Ray features diagnostic. We will also discuss neonatal findings, risk factors and prognosis of this condition...

A 47-year-old male presented with haematuria and flank pain for two weeks. Ultrasonography and renal scan revealed a poorly functioning left kidney with multiple calculi. Simple nephrectomy was performed and the specimen revealed a mass in his renal pelvis which showed both carcinomatous and sarcomatous components on microscopy. The sarcomatous component consisted of diffuse pleomorphic osteoblasts with intervening lacy osteoid, giving an osteosarcoma-like appearance. These areas of tumour were strongly positive for vimentin and osteopontin...

Sacral-iliac fixation techniques may be indicated in the management of various lumbosacral pathologies including spinal degeneration, infection, tumour resection, fracture, pseudarthrosis, correction of spinal deformities involving long fusion constructs to the sacrum and cases with poor sacral fixation. There are a number of options for lumbosacral fixation each with their own advantages and disadvantages. Though S2-alar-iliac (S2AI) have demonstrated promising advantages over alternatives, the complex anatomy of the spinopelvic region demands precise insertion of the screws to create a biomechanically robust construct safely...

Spinal subdural hematomas (SSDHs) are rare and usually associated with bleeding diatheses, trauma, iatrogenic injury, spinal vascular malformations, or intraspinal tumors. We report a case of a 75-year-old male who developed a symptomatic lumbosacral SSDH after undergoing resection of a right temporal glioblastoma multiforme. The patient subsequently recovered and was discharged home. Over the next two weeks he developed progressively worsening symptoms of lower back pain, lower extremity weakness, and urinary retention...

In 2005, an adult male was excavated in the cloister of the former Convent of the Holy Spirit, in the Franciscan Province of Holy Mary of Arrábida, Lisbon district. From the anterior part of the sacrum, a darker organic agglomeration was collected and studied for intestinal parasites. Samples were rehydrated with Lycopodium tablets in a Na3PO4 5% solution for 72h, followed by the swirl technique. Organic material was concentrated at 2500rpm. At least 20 slides of each sample were examined using a light/polarized microscope...

S Meaume, M Marty, D Colin
OBJECTIVE: In patients with reduced mobility, specialised pressure-relieving supports (mattresses, beds and cushions) are widely used to reduce or relieve the interface pressure between the skin and support surfaces to prevent incidence of pressure ulcers (PUs). The primary objective of these two observational studies was to assess the incidence of PUs in patients at high risk of PUs, seated in a wheelchair using a single- or multi-compartment air cushion. The level of patient satisfaction with the comfort and the views of the care team that used the air cushions were considered as secondary objectives...

PURPOSE: To determine whether a curvilinear supine position increases the contact area between the subject and the surgical table, reduces interface pressures within contact areas, and improves comfort. DESIGN: This observational study was completed to establish proof-of-concept to determine differences between 2 positions (supine and curvilinear) on interface pressure of 5 at-risk anatomical locations, overall contact area, and subjects' comfort level. SUBJECTS AND SETTING: The study was conducted at the operating theater of a tertiary teaching hospital in Wuhan, China...

Context Caudal regression syndrome is a rare disorder, not well described in the literature. Findings Authors treated two patients with congenital absence of thoracolumbar vertebrae and lower limbs paraplegia. Patients had hypoplasia of the lower trunk and extremities with motion between upper and lower torso. Imaging showed caudal spine agenesis, but cleft sacrum was present. Due to severe kyphotic deformity and spinal instability, deformity correction and posterior fusion was performed at the age 6 and 8...

Chronic neuropathic pain is often refractory to conventional medical treatments and leads to significant disability and socio-economic burden. Dorsal root ganglion (DRG) stimulation has recently emerged as a treatment for persistent neuropathic pain, but creating a strain relief loop on the S1 level has thus far been a challenging technical component of DRG lead placement. We describe a refined technique for strain relief loop formation on the S1 level using a transforaminal approach that we employed in a 45-year old patient with intractable foot pain...

BACKGROUND: Many studies suggest that impairment of motor control is the mechanical component of the pathogenesis of painful disorders in the lumbo-sacral region; however, this theory is still unproven and the results and recommendations for intervention remain questionable. The need for a force to compress both innominate bones against the sacrum is the basis for treatment of pregnancy-related pelvic girdle pain (PGP). Therefore, it is advised to use a pelvic belt and do exercises to enhance contraction of the muscles which provide this compression...

The sacrum - consisting of those vertebrae that articulate with the ilia - is the exclusive skeletal connection between the hindlimbs and axial skeleton in tetrapods. Therefore, the morphology of this portion of the vertebral column plays a major role in the evolution of terrestrial locomotion. Whereas most extant reptiles only possess the two plesiomorphic sacral vertebrae, additional vertebrae have been incorporated into the sacrum multiple times independently among early-diverging archosaurian (crocodylians + birds) clades...

OBJECTIVES: Differentiating human from nonhuman fragmented bone is often accomplished using histological methods if the observation of gross morphology proves insufficient. Linearly oriented primary and/or secondary osteonal systems, commonly referred to as osteon bands, are described as a strong indicator of nonhuman bone, particularly the occurrence of multiple bands. This phenomenon has been conventionally documented using two-dimensional (2D) histology, but such analyses are destructive and typically limited to a single cross-section...

The purpose of this investigation was to determine the feasibility of using a single inertial measurement unit (IMU) placed on the sacrum to estimate 3-dimensional ground reaction force (F) during linear acceleration and change of direction tasks. Force plate measurements of F and estimates from the proposed IMU method were collected while subjects (n=15) performed a standing sprint start (SS) and a 45° change of direction task (COD). Error in the IMU estimate of step-averaged component and resultant F was quantified by comparison to estimates from the force plate using Bland-Altman 95% limits of agreement (LOA), root mean square error (RMSE), Pearson's product-moment correlation coefficient (r), and the effect size (ES) of the differences between the two systems...
