RESUMO
The development and diffusion of minimally invasive (MI) approaches have coincided with improvements in magnification systems. The exoscope will probably open a new era in new technologies in spinal surgery. This study reports a retrospective series of 19 thoracolumbar (T11-L2) burst fractures with anterior column failure and cord compression, treated with MI corpectomy and spinal decompression assisted by a three-dimensional high-definition exoscope (Video 1). Exclusion criteria were pathologic or osteoporotic fractures, multilevel fractures, and previous surgery at the site of the fracture. Three key indicators were recorded: surgical time, blood loss, and intraoperative complications. A questionnaire was administered to assess the users' exoscope experience with ergonomics, preparation, magnification, image definition, illumination, and user-friendliness, compared with the operative microscope. To the best of our knowledge, this is the first study reporting on exoscope-assisted MI corpectomy. This procedure permitted low blood loss and less surgical time without intraoperative complications. The exoscope offers clear advantages in terms of ergonomics, definition, and user-friendliness. Moreover, it is a suitable instrument for training and education, providing an opportunity for better interaction with other members of the surgical staff.

Objectives: During the last decades, spine surgery has grown exponentially. In spite of that, it remains a surgical specialty without a well-defined own certification. It is usually carried out, separately, by neurosurgeons and orthopedic surgeons, even if there is an overlapping of competence and skills. Materials and Methods: In our hospital, from January 2019, a systematic protocol called integrated spine trauma team protocol (ISTTP) was implemented to improve the management of traumatic spinal injuries in a multidisciplinary way. It is characterized by a specific algorithm from diagnosis to postoperative care. According to the new protocol, orthopedic spinal surgeons and neurosurgeons work together as an integrated spine trauma team. The authors analyzed, retrospectively, the results obtained by comparing patients treated before and after the application of the ISTTP. Results: The new protocol allowed a statistically significant reduction in waiting time before surgery and complication rate. Moreover, early discharge of patients was recorded. To the best of our knowledge, this is the first study that described a specific algorithm for a standardized multidisciplinary management of the spinal trauma with combined orthopedic and neurosurgeon expertise. Conclusion: Our preliminary results suggest that the application of our ISTTP leads to better results for treating traumatic spinal injury (TSI).
RESUMO
Background: Vertebral arthrodesis for degenerative pathology of the lumbar spine still remains burdened by clinical problems with significant negative results. The introduction of the sagittal balance assessment with the evaluation of the meaning of pelvic parameters and spinopelvic (PI-LL) mismatch offered new evaluation criteria for this widespread pathology, but there is a lack of consistent evidence on long-term outcome. Methods: The authors performed an extensive systematic review of literature, with the aim to identify all potentially relevant studies about the role and usefulness of the restoration or the assessment of Sagittal balance in lumbar degenerative disease. They present the study protocol RELApSE (NCT05448092 ID) and discuss the rationale through a comprehensive literature review. Results: From the 237 papers on this topic, a total of 176 articles were selected in this review. The analysis of these literature data shows sparse and variable evidence. There are no observations or guidelines about the value of lordosis restoration or PI-LL mismatch. Most of the works in the literature are retrospective, monocentric, based on small populations, and often address the topic evaluation partially. Conclusions: The RELApSE study is based on the possibility of comparing a heterogeneous population by pathology and different surgical technical options on some homogeneous clinical and anatomic-radiological measures aiming to understanding the value that global lumbar and segmental lordosis, distribution of lordosis, pelvic tilt, and PI-LL mismatch may have on clinical outcome in lumbar degenerative pathology and on the occurrence of adjacent segment disease.
RESUMO
STUDY DESIGN: Spinal cord decompression in thoracolumbar burst fractures is challenging. Development of minimally invasive approaches and the improvement in new magnification technologies allowed a better and safer surgical treatment for these complex spinal injuries. We reported our experience in the minimally invasive surgical treatment of thoracolumbar burst fractures with spinal cord compression supported by high-definition (HD) three-dimensional (3D) Video-assisted telescope operating monitor (VITOM) or exoscope. OBJECTIVES: To assess the role and potential advantages of exoscope in the minimally invasive surgery of traumatic thoracolumbar spinal cord compression comparing traditional magnification systems. SETTING: The study was conducted in a Northern Italy Spinal Trauma Center. METHODS: We reported 10 consecutive thoracolumbar (T11-L2) burst fractures associated with spinal cord compression treated with minimally invasive corpectomy and exoscope-assisted spinal decompression. Three main indicators were retrospectively analyzed: surgical time, blood loss, and intraoperative complications. The data were compared with those obtained from an equal sample of 10 procedures performed by the same surgeon with the same technique, but traditional microscope assisted. User impressions in terms of ergonomics, magnification, and image quality were rated differently. RESULTS: A small reduction of surgical time and blood loss were observed in the exoscope assisted group. There were no intraoperative complications attributed to visualization mode or conversion to the traditional microscope in any procedure. In our experience the exoscope allowed a better magnification and image definition with better ergonomics and user-friendliness. CONCLUSIONS: In our preliminary experience the exoscope new technology is a safe and effective tool for spinal cord minimally invasive decompression in thoracolumbar burst fractures. The stereoscopic vision provided by 3D images seems to be crucial in hand eye coordination. There are clear advantages in terms of maneuverability, wide field of view, deep focus, and more comfortable posture for the spinal surgeon.

In the pandemic disease caused by SARS-CoV-2 virus, trauma surgery continued the management of patients with fractures. The purpose of the study is to evaluate mortality and morbidity in orthopedic trauma patients surgically treated with a diagnosis of COVID-19 infection, comparing them to a control group of COVID-19 negative. We retrospectively identified patients admitted to our Emergency Room from March 8th to May 4th 2020 (time frame corresponding to the first wave of the pandemic peak, one of the most severe in the world at that time) with a diagnosis of fracture that were subsequently surgically treated. We applied a dedicated pathway for the management of COVID-19 trauma patients allowed to perform an early surgery and short hospitalization. For each patient included demographics, clinical, laboratory, radiological data and type of treatment for COVID-19 infection were collected. Sixty-five (65) patients were identified. Of those, 17 (6 women and 11 men, mean age 63.41 years old, mean ASA grade 2.35) were COVID-19 positive (study group), while the others were control group (mean age 56.58 years old, mean ASA grade 2.21). In the study group, the preoperative laboratory tests showed leukocytosis in six and lymphopenia in 15 cases. Fourteen patients had a high level of C-reactive protein. Fifteen patients had an abnormal level of D-dimer. The mortality recorded was 5.8% and 4.1% in the study and control group respectively. Perioperative adverse events were registered in 5 cases (29.4%) in the study group and in 8 (16.6%) in the control group (p>0.05). Dedicated COVID-19 trauma pathway with the aim of an early surgery could be key for a better result in terms of mortality and morbidity. Age and ASA grade could represent independent risk factors for perioperative complications.

INTRODUCTION: Dialysis-related amyloidosis (DRA) can lead to various degenerative conditions but rarely involves the spine with a spinal cord compression. CASE REPORT: The authors describe a progressive tetraparesis (AIS-B) in a 57-year-old woman with upper cervical dialysis-related amyloidoma. Magnetic resonance imaging (MRI) showed a solid focal mass lesion at the C2-odotoid level with severe spinal cord compression. Computed tomography (CT) outlined multiple lytic lesions in C1 lateral masses and odontoid process. The patient underwent urgent surgical treatment. A posterior C1-C2 spinal cord decompression with biopsy followed by occipito-cervical posterior fixation was performed. Histopathological examination revealed amyloid deposits representing DRA. An immediately postoperative neurological improvement was observed. DISCUSSION: Even if the spinal amyloidoma is extremely rare, this condition has to be suspected in a long-term hemodialysis patient suffering from progressive neurological deficits. Differential diagnosis is mandatory between infections, rheumatologic and neoplastic lesions. Imaging evaluation with CT and MRI is recommended in order to assess the characteristics of the pathological mass, the extension of lytic lesions and the entity of neurological compression. Surgical treatment is mandatory if clinical evidence of root or spinal cord compression is present.

PURPOSE: The increased life expectancy of patients with myelomeningocele led to the necessity of new management for addressing complex spine deformities with severe pelvic obliquity. Tethered cord release (TCR) and spinal fusion were described as treatment options. However, nowadays, the surgical strategy is not well defined and high rates of mechanical failures and complications are reported. Our aim was to propose a new two-stage surgical pathway to treat a selected group of severe myelomeningocele scoliosis. METHODS: This is a retrospective series of myelomeningocele scoliosis in paralytic adolescent patients treated with concurrent TCR and posterior spinal fusion (PSF), followed by delayed anterior fusion (ASF) through minimally invasive lateral approach. Inclusion criteria were as follows: evolutive scoliosis in tethered cord syndrome and paraplegia, main curve >70°, pelvic obliquity >20°, and age between 10 and 18 years. Clinical, surgical, and radiographic parameters were evaluated preoperatively and at a mean follow-up (FU) of 2.8 years. RESULTS: Six patients out of 58 met the inclusion criteria and were included in the study (mean age 12.3 years old). The mean curve and pelvic obliquity correction were 68.8% and 82%, respectively. No loss of correction was recorded at FU. One case of cerebrospinal fluid leakage requiring revision surgery was recorded. CONCLUSION: To the best of our knowledge, this is the first study proposing a two-stage surgical pathway for severe MMC spinopelvic deformity treatment. Concurrent TCR and PSF with delayed minimally invasive ASF permitted to minimize complications providing good fusion rates without loss of correction and implant failure.

The COVID-19 virus is a tremendous burden for the Italian health system. The regionally-based Italian National Health System has been reorganized. Hospitals' biggest challenge was to create new intensive care unit (ICU) beds, as the existing system was insufficient to meet new demand, especially in the most affected areas. Our institution in the Milan metropolitan area of Lombardy, the epicentre of the infection, was selected as one of the three regional hub for major trauma, serving a population of more than three million people. The aims were the increase the ICU beds and the rationalization of human and structural resources available for treating COVID-19 patients. In our hub hospital, the reorganization aimed to reduce the risk of infection and to obtained resources, in terms of beds and healthcare personnel to be use in the COVID-19 emergency. Non-urgent outpatient orthopaedic activity and elective surgery was also suspended. A training programme for healthcare personnel started immediately. Orthopaedic and radiological pathways dedicated to COVID-19 patients, or with possible infection, have been established. In our orthopaedic department, we passed from 70 to 26 beds. Our goal is to treat trauma surgery's patient in the "golden 72 hours" in order to reduce the overall hospital length of stay. We applied an objective priority system to manage the flow of surgical procedures in the emergency room based on clinical outcomes and guidelines. Organizing the present to face the emergency is a challenge, but in the global plan of changes in hospital management one must also think about the near future. We reported the Milan metropolitan area orthopaedic surgery management during the COVID-19 pandemic. Our decisions are not based on scientific evidence; therefore, the decision on how reorganize hospitals will likely remain in the hands of individual countries.
