A 21 year female polytraumatized patient was admitted to our unit after a serious motorbike accident. We carried out CT imaging, which confirmed the fracture of the C-II vertebra and compression of spinal cord. Futhermore, the diagnostic investigations detected the compound and comminuted fracture of the left humerus and femur; the sacrum and the pubic bones were broken as well. After the stabilization of the cervical vertebra, a tracheotomy and the fixation of her limbs were performed. She spent 1.5 years in our unit...

OBJECTIVE: Patients undergoing long-segment fusions from the lower thoracic (LT) spine to the sacrum for adult spinal deformity (ASD) correction are at risk for proximal junctional kyphosis (PJK). One mechanism of PJK is fracture of the upper instrumented vertebra (UIV) or higher (UIV+1), which may be related to bone mineral density (BMD). Because Hounsfield units (HUs) on CT correlate with BMD, the authors evaluated whether HU values were correlated with PJK after long fusions for ASD...

OBJECTIVE: Opportunistic Hounsfield unit (HU) determination from CT imaging has been increasingly used to estimate bone mineral density (BMD) in conjunction with assessments from dual energy x-ray absorptiometry (DXA). The authors sought to compare the effect of teriparatide on HUs across different regions in the pelvis, sacrum, and lumbar spine, as a surrogate measure for the effects of teriparatide on lumbosacropelvic instrumentation. METHODS: A single-institution retrospective review of patients who had been treated with at least 6 months of teriparatide was performed...

This study investigated the effects of gender and the manipulation of the preferred stroke rate on swimming performance and arm coordination in elite front crawl swimmers. Nineteen swimmers performed a dual task, i.e. imposed stroke rate and maximal speed. They swam nine 25-m trials at maximal speed twice: one trial at the preferential stroke rate, one trial at maximal stroke rate and seven trials at stroke rates between 41 and 59 cycles.min-1 imposed by an Aquapacer. Stroke rate, arm stroke phases and arm coordination were computed from an inertial measurement unit on each forearm and one on the sacrum...

BACKGROUND: There has been a considerable rise in the number of musculoskeletal/orthopaedic oncology fellowships and subsequently, orthopaedic oncologists, in the nation. National societies have been concerned that the increasing number of orthopaedic oncologists, coupled with a limited number of patients with bone and soft-tissue sarcomas in the country, may have led to an unintended impact on the training spectrum and/or exposure of orthopaedic oncology fellows-in-training over time...

Inflammatory myofibroblastic tumours (IMTs) are rare lesions. We report a case of a 55 year-old male, admitted with a pneumonia. Further investigation revealed a left lower lobe mass and enlarged mediastinal lymph nodes. Cytology of the bronchoalveolar lavage suggested a squamous cell carcinoma. He received four cycles of chemotherapy followed by a left lower lobectomy. Pathological analysis was compatible with IMT. Three months after surgery, a new IMT nodule located in the lingula was excised. Four months later,endobronchial involvement and the presence of liver nodules were detected...

Background: Debate on whether to stop fusion at L5 or to extend fusion to S1 in a long spinal construct has been a controversial topic in spine surgery. Fewer data are available to support whether to include a prior solid fusion at L4-L5 or to extend to S1 during a proximal extension of fusion to T10. The purpose of this review is to report and discuss 2 cases of L5 vertebra fracture after proximal extension of solid L4-L5 fusion to T10 and to provide a guideline to surgeons based on the available literature...

Primary tumors of sacrum are rarely seen, and the differential diagnosis is extensive, such as chordomas, giant cell tumors, and schwannomas. Sacral intraosseous schwannomas (IOSs) are very rare and encompass approximately 1%-5% of all spinal schwannomas. Melanotic schwannomas (MSs) are categorized as an unusual variant of benign schwannomas; however, they sometimes follow a malignant course. The authors present a case of MS with intraosseous extension into sacrum in a 48-year-old male arising from the left S2 nerve root...

BACKGROUND: Sacral U‑shaped fractures are rare but severe injuries. Due to the resulting spinopelvic dissociation they are highly unstable. Reduction and stabilization are usually required and decompression may be necessary due to frequent concomitant neurological injuries. In the literature there is no consensus with respect to the selection of the surgical approach. CASE PRESENTATIONS: After a road traffic accident an 18-year-old woman suffered a U-fracture of the sacrum type II according to Roy-Camille and was treated with bilateral double sacroiliac screw osteosynthesis and sacral laminectomy...

During ganglion impar block, the needle may approach the presacral space and the sacrum may be penetrated during caudal anesthesia. Because the rectum is in front of the sacrococcyx and is thus at risk for puncture, it is important to determine the distance between the sacrococcyx and rectum, as well as the thickness of the sacrococcyx.Computed tomography was used to measure the distance between the rectum and sacrococcyx, as well as the thickness of the sacrococcyx. The distances between the coccyx and rectum, sacrococcygeal joint and rectum, sacral level 5 ('sacrum 5') and rectum, and 'sacrum 4 to 5 junction' and rectum were measured...

INTRODUCTION: The choice of therapy for fragility fractures of the pelvis (FFP) is largely determined by the diagnosed fracture morphology. It is now unclear whether the change in diagnostic options - sensitive detection of fracture oedema in the sacrum using MRI and dual-energy computed tomography (DECT) - has an impact on the therapeutic consequences. The aim of this retrospective study was therefore to evaluate the change in the diagnostics used and the resulting therapy regimen in our patient population...
