Vertebral Candidiasis, the State of the Art: A Systematic Literature Review.

OBJECTIVE: In recent years, Candida spondylodiscitis has represented an increasingly emerging disease in clinical practice. This condition requires long-term antibiotic therapy and sometimes surgical treatments. The main purpose of this study is to investigate the epidemiology, clinical and radiological aspects, treatment protocols, and outcomes of Candida-mediated vertebral osteomyelitis. METHODS: A systematic review of the English literature was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines.The research was conducted on Medline, Cochrane library, PubMed, and Scopus using as search terms "vertebral"; "spinal"; "infection"; "spondylodiscitis"; "discitis"; "osteomyelitis"; "Candida"; and "Candidosis." A case of vertebral candidiasis that was surgically managed was also reported. RESULTS: In total, 88 articles were included in our systematic review. Including the reported case, our analysis covered 113 cases of vertebral candidiasis. Candida albicans was isolated in 64 cases (56.1%), Candida tropicalis in 21 (18.4%), Candida glabrata in 14 (12.3%), and Candida parapsilosis in five (4.4%). The mean duration of the follow-up was 395 days. Finally, 87 (82%) patients completely recovered, ten (9.4%) died, and nine (8.5%) reported sequelae. CONCLUSION: This systematic review summarized the state of the art on vertebral candidiasis, describing data on its clinical features, diagnostic criteria and current limitations, and treatment alternatives and their outcomes.

Long-Term Clinical and Radiographic Outcomes After Bryan Cervical Disk Arthroplasty: A Systematic Literature Review.

Introductionː Cervical disk arthroplasty is a potential alternative procedure to anterior cervical decompression and fusion for the treatment of cervical disk disease. The aim of the study was to perform a systematic literature review on long-term clinical and radiological outcomes after Bryan cervical disk arthroplasty.Material and Methodsː A systematic literature review was performed according to PRISMA guidelines via PubMed and Embase, Scopus, and the Cochrane Library database by using the following keywords: "Bryan prosthesis"; "cervical disk arthroplasty"; "outcomes"; and "long-term follow-up." Eight articles with at least 10 years of follow-up were considered for eligibility.Resultsː In total, 481 patients were enrolled in the studies. Because of the occurrence of multiple treated levels, 588 arthroplasties were performed, divided as follows: 12 C3/4 cervical disk arthroplasties (2.01%), 63 C4/5 (10.71%), 325 C5/6 (55.27%), and 188 C6/7 (31.97%). The mean preoperative cervical lordosis was 13.6 ± 9.3°, whereas the last follow-up value was 12.8 ± 8.7°. In the last follow-up, the mean segmental range of motion was 8.2 ± 3.3°.Discussion: Recent studies have suggested that cervical disk arthroplasty should be safely performed in healthy young patients with disk degeneration who may need future revision surgery. The results suggest that this procedure preserves native cervical spinal biomechanics at long-term follow-up with acceptable adjacent segments disease and periprosthetic ossifications.Conclusionsː Cervical disk arthroplasty has good long-term device survival, motility, adjacent segment degeneration, and clinical outcomes. Therefore, it represents a valid alternative for the treatment of cervical spine degenerative pathologies, especially in young patients.

The role of femoral obliquity angle and T1 pelvic angle in predicting quality of life after spinal surgery in adult spinal deformities.

BACKGROUND: Adult spinal deformities (ASD) represent a growing clinical condition related to chronic pain, disability and reduction in quality of life (QoL). A strong correlation among spinal alignment, spinopelvic parameters and QoL after spinal fusion surgery in ASD patients was thoroughly investigated over the last decade, However, only few studies focused on the relationship between lumbo-pelvic-femoral parameters - such as Femoral Obliquity Angle (FOA), T1 Pelvic Angle (TPA) and QoL. METHODS: Radiological and clinical data from 43 patients surgically treated with thoracolumbar posterior spinal fusion for ASD between 2015 and 2018 were retrospectively analyzed. The primary outcomes were the correlation between preoperative spino-pelvic-femoral parameters and postoperative clinical, functional outcomes and QoL. Secondary outcomes were: changes in sagittal radiographic parameters spino-pelvic-femoral, clinical and functional outcomes and the rate of complications after surgery. RESULTS: Using Spearman's rank correlation coefficients, spinopelvic femoral parameters (FOA, TPA, pre and post-operative) are directly statistically correlated to the quality of life (ODI, SRS-22, pre and post-operative; > 0,6 strong correlation, p <  0.05). Stratifying the patients according pre preoperative FOA value (High FOA ≥ 10 and Normal/Low FOA <  10), those belonging to the first group showed worse clinical (VAS: 5.2 +/- 1.4 vs 2.9 +/- 0.8) and functional outcomes (ODI: 35.6+/- 6.8 vs 23.2 +/- 6.5) after 2 years of follow-up and a greater number of mechanical complications (57.9% vs 8.3% p <  0.0021). CONCLUSION: Based on our results, preoperative FOA and TPA could be important prognostic parameters for predicting disability and quality of life after spinal surgery in ASD patients and early indicators of possible spinal sagittal malalignment. FOA and TPA, like other and better known spinopelvic parameters, should always be considered when planning corrective surgery in ASD patients.

Single-level Bryan cervical disc arthroplasty: evaluation of radiological and clinical outcomes after 18 years of follow-up.

PURPOSE: Many studies reported mid-term clinical and radiological outcomes after cervical disc arthroplasty. Only a few studies analysed the long-term results. The aim of the study was to evaluate the clinical and radiological outcomes in patients treated with single-level Bryan cervical disc arthroplasty after 18 years of follow-up. METHODS: This study was a retrospective analysis of institutional databases concerning patients treated with Bryan cervical disc arthroplasty. SF36 PCS, NDI and VAS were used to evaluate clinical and functional outcomes. Standard, flexion-extension X-ray and MRI were used to evaluate the radiological results. RESULTS: Fifty-seven patients treated with single-level Bryan cervical disc arthroplasty completed the 18-year follow-up. At the final follow-up, a residual movement was observed in 32 patients (56%). The treated level range of motion decreased from 10.1° pre-operatively to 6.1° at the last follow-up (p = 0.0021). The range of motion of the adjacent segments and of the cervical spine had no significant change. Disc degeneration of the adjacent segment after 18-year follow-up was observed in 77.1% of treated patients. CONCLUSION: The clinical and radiographic outcomes 18 years after surgery are acceptable. The treated level range of motion reduction and the adjacent segment degeneration seems not to affect the clinical results after 18 years of follow-up.

Minimally invasive surgery procedure in isthmic spondylolisthesis.

PURPOSE: The aim of the study was to evaluate the efficacy and safety of the direct lateral approach to the lumbar spine in the treatment of painful isthmic spondylolisthesis in adults. METHODS: Twenty-one patients affected by isthmic spondylolisthesis and treated with extreme lateral interbody fusion and posterior percutaneous pedicle screw fixation were enrolled. All included patients were clinically evaluated with Oswestry Disability Index, SF36 and Visual Scale Anatomy (VAS) for back pain at 1, 3 months and at 1 year. RESULTS: The mean correction of vertebral slippage measured on lateral lumbar X-ray was 56.3% (p = 0.002). The average preoperative VAS score was 7.1, at 1 year decreasing to 2.2 (p = 0.001). The patients had an average preoperative "Oswestry Disability Index" of 36.8 and 24.1% after 1 year (p = 0.02). The preoperative Short-Form 36 Physical Health was equal to 33.8, 72.1% after 1 month, to 76.3% after 3 months and to 83.2% (p = 0.001) after 1 year of follow-up. There were no signs of implant loosening at 1-year CT scan examination in any of the patients. CONCLUSION: The study showed that the extreme lateral approach to the lumbar spine in case of isthmic spondylolisthesis is a reliable and safe option to the most common open procedures. In the authors' opinion, XLIF procedures allow a good correction of the listhesis associated with good clinical and radiographic results.

Thoracic synovial cyst as cause of cord compression in a patient with Charcot-Marie-Tooth disease.

An 80-year-old male patient affected by Charcot-Marie-Tooth (CMT) disease came to our attention in July 2020, for the occurrence of low back pain and lower limb weakness, and also saddle anesthesia, urinary and faecal retention were referred. His diagnosis of CMT is dated back to 1955 and through the years, the clinical picture slowly worsened but never got particularly severe. The quick symptoms outbreak and the presence of urinary disturbances were red flags, which lead us to direct the diagnostic orientation elsewhere. A Magnetic Resonance Imaging of the thoraco-lumbar spinal cord was then performed and it was suggestive for synovial cyst at T10-T11. The patient underwent a decompression with laminectomy and then stabilized through arthrodesis. In the very next days after the surgery, the patient showed a sudden and significant improvement of his condition. At the last visit, he showed a remarkable relief of the symptoms, walking by himself.

The value of megaprostheses in non-oncological fractures in elderly patients: A short-term results.

INTRODUCTION: The management of both hip and distal femur fractures as well as periprosthetic fractures can be challenging for orthopaedic surgeons. The use of megaprosthetic implants could provide substantial advantages in elderly population affected by complex fractures. The aim of the study was to evaluate the effectiveness of megaprosthetic implants for treating hip and distal femur fractures as well as periprosthetic fractures in elderly. MATERIAL AND METHODS: From January 1st 2015 to December 31st 2019, patients treated for proximal or distal femoral fractures with severe bone loss or failure of previous surgery were retrospectively reviewed. Patients were divided into two group based on diagnosis: proximal femur fractures (group A) and distal femur fractures (group B). Subsequently, patients underwent hip (group A) or knee (group B) megaprosthesis. Self-assessed questionnaires were administered to all patients pre and postoperatively. Primary outcome was the Activity Daily Living. Secondary outcomes were: Instrumental Activity Daily Living, Short Form-12, Oxford knee or hip score, complications. Charlson score, Harris classification for hip or Anderson Orthopaedic Research Institute score and complication were recorded. All patients underwent a radiological follow up to rule out implant loosening and mobilization. Pre and postoperative functional score comparisons in each group were undertaken. Significance was set p ≤ 0.05. RESULTS: Twelve patients were finally included in the study. There were 6 male and 6 females, the mean age was 72,9 years old (± 7,4); the mean BMI was 29,8 points (± 4.5). The mean follow-up was 2.9 years (± 1.4). No differences could be found between pre and postoperative evaluation in each group. No aseptic loosening, dislocation, mobilization or radiolucency were recorded during the follow-up. In group A, two surgical site infections (2/6 patients) and one pneumonia (1/6 patients) were recorded. In group B, two surgical site infections occurred (2/6 patients). All patients were treated by antimicrobial oral therapy with complete regression. CONCLUSION: The use of hip and knee megaprosthetic implants in traumatology is a safe and viable option in elderly patients.

Symptomatic vertebral hemangioma during pregnancy period: A case series and systematic literature review.

Vertebral Hemangioma (VH) is a benign tumor usually symptomless and discovered incidentally. Pregnancy, because of several hormonal and physiologic changes, is a recognized risk factor coinciding with the development of a rapid onset of neurological symptoms in patients affected by VH. In the Literature, sporadic cases of neurological symptoms have been described, which occurred during pregnancy, but only rarely the onset of symptoms was reported after pregnancy and childbirth. Usually surgical treatment is reserved for severe cases with rapid onset of neurological symptoms. However, the use of conservative treatments is still a topic of debate In the present study, we report a series of patients affected by VH become symptomatic during or after pregnancy along with a systematic review of the Literature.

Spinal surgery in COVID-19 pandemic era: One trauma hub center experience in central-southern Italy.

The aim of the study is to analyze and report the results of the surgical activity in a spinal unit of a trauma hub in central Italy during COVID-19 pandemic. Surgical activity was compared between COVID 19 pandemic and the same period of time in 2019 at our institution. A 50% reduction of surgical procedures during the last three months was observed compared with the same period of time in 2019. The compliance with the containment rules for the spread of the infection, were sufficient to allow safe surgical activity for the medical teams and patients.

Etiopathogenesis of Traumatic Spinal Epidural Hematoma.

Spinal epidural hematoma (SEH) is a rare cause of nerve root or cord compression; its pathogenesis is not always clearly recognizable. The aim of this paper was to investigate possible etiopathological factors in a consecutive series of patients affected by traumatic SEH treated at our institution. Seven patients with neurologic impairment due to traumatic SEH were retrospectively analyzed after diagnosis and surgical treatment. Thoracic localization was found in 5 cases, and lumbar and cervical localization were found in 1 patient each. One patient was affected by ankylosing spondylitis and one by diffuse idiopathic skeletal hyperostosis. SEH was associated with spine fractures in 6 cases. Only 2 cases of traumatic SEH resulted from high-energy trauma. All patients underwent surgical decompression within 24 hours after admittance to the hospital. Three patients recovered completely, 3 remained paraplegic, and 1 remained monoplegic. Several concomitant conditions are suggested to be predisposing factors for the development of SEH, although its inherent mechanism is still unknown. Two patients in the present series were affected by rheumatologic disorders, confirming the elevated incidence of hematomas in such patients compared to the normal population. Three very unusual cases of SEH occurred in senile patients affected by osteoporotic fractures. Early diagnosis and urgent decompression of the hematoma remain mandatory.
