BackgroundThe interest on the role of Denosumab in the treatment strategy of giant cell tumor of the spine is growing. En bloc resection is considered the Enneking appropriate treatment, but morbidity and functional loss are sometimes unacceptable. Denosumab could play a role as a stand-alone treatment, but also as preoperative treatment or as postoperative after intralesional surgery.Materials and methodsA cohort of 10 out of 12 cases of spinal GCT consecutively treated with Denosumab are analyzed and discussed compared to the cases reported in the literature. A staging of the radiological effect of the treatment is proposed.ResultsThe stand-alone and postoperative treatments are still running (12 to 88 months). One therapy was stopped after 15 months, once a satisfactory local effect was achieved, but the treatment had to be restarted 2 months later due to the recurrence of the erosive images. The new treatment was successful. At 1-year follow-up after the gross total excision followed by postoperative Denosumab treatment, no evidence of local recurrence was found. The preoperative treatment duration ranged from 3 to 24 months. No local recurrence followed the en bloc resections.ConclusionsDenosumab alone is effective in relieving pain, increasing the ossification and sometimes reducing the tumor volume. It can be considered an excellent solution in spine GCTs whose surgical treatment cannot be Enneking appropriate or is associated with unacceptable morbidity or loss of functions. It is still impossible to state when to safely stop the treatment. Denosumab also plays a role as preoperative protocol.These slides can be retrieved under Electronic Supplementary Material.

Background: Patients with inflammatory bowel disease (IBD) are at an increased risk of developing Clostridioides difficile infection (CDI). Treatment of CDI in patients with IBD is challenging due to higher failure rates and concomitant IBD activity. Objectives: We performed a multicentre cohort study in patients with IBD who received fecal microbiota transplantation (FMT) for recurrent CDI (rCDI), to further investigate factors that influence the clinical outcome and course of both rCDI and IBD. Design: This is a multicentre cohort study conducted in five European FMT centres. Methods: Adult IBD patients treated with FMT for rCDI were studied. Cure was defined as clinical resolution of diarrhoea or diarrhoea with a negative C. difficile test. The definition of an IBD flare was record based. Long-term follow-up data were collected including new episodes of CDI, IBD flares, infections, hospital admissions, and death. Results: In total, 113 IBD patients underwent FMT because of rCDI. Mean age of the patients was 48 years; 64% had ulcerative colitis. Concomitant rCDI was associated with an IBD flare in 54%, of whom 63% had received IBD remission-induction therapy prior to FMT. All FMT procedures were preceded by vancomycin treatment, 40% of patients received FMT via colonoscopy. CDI cure rate was 71%. Long-term follow-up data were available in 90 patients with a median follow-up of 784 days (402–1251). IBD activity decreased in 39% of patients who had active IBD at baseline, whereas an IBD flare occurred in only 5%. During follow-up of up to 2 years, 27% of the patients had infections, 39% were hospitalized, 5% underwent colectomy, and 10% died (median age of these latter patients: 72 years). Conclusion: FMT for rCDI in IBD patients is safe and effective, and IBD exacerbation after FMT is infrequent. Further studies should investigate the effects on IBD course following FMT.

PurposeSpinal bone tumors include a heterogeneous broad of primary or metastatic lesions that may present as incidental findings or manifest with painful symptoms and pathological fractures. Optimal management of spine bone lesions is often difficult and treatment algorithms are usually solidly based on surgery. We aimed to evaluate the contribution of trans-arterial embolization in this field, with particular attention to the procedure efficacy, technical difficulties and complications.MethodsWe present a literature review on the role of trans-arterial embolization in the management of spinal bone tumors, both primary and metastatic, evaluating its contribution as preoperative treatment, palliative procedure and standalone curative strategy.ResultsTrans-arterial embolization provides an important contribution to reducing surgery hemorrhagic risks, offering a better visualization of the operating field, and possibly increasing tumor susceptibility to chemotherapy or radiation therapy. Nonetheless, it plays an important part in pain palliation, with the unquestionable advantage of being easily repeatable in case of necessity. Its curative role as a standalone therapy is still subject of debate, and at the present time, satisfactory results have been recorded only in the treatment of aneurysmal bone cysts.ConclusionPercutaneous trans-arterial embolization has established as a highly useful minimally invasive procedure in the management of spinal bone lesions, particularly as adjuvant preoperative therapy and palliative treatment.

Purpose Identify risk factors, enabling reduction of the rate of complications and improve outcome in en bloc resection surgeries. Methods A retrospective study of prospective collected data of 1681 patients affected by spine tumors treated from 1990 to 2015 by the same team. Results A total of 220 en bloc resections that were performed on 216 patients during that period. Most of the tumors were primary—165 cases (43 benign and 122 malignant), metastases occurred in 55 cases. Median FU was 45 months (0–371). 153 complications were observed in 100 patients (46.2 %). 64 (30 %) suffered one complication, while the rest had two or more. There were 105 major and 48 minor complications. Seven patients (4.6 %) died as a result of complications. The combined approach, neoadjuvant chemotherapy and neoadjuvant radiotherapy were statistically significant independent risk factors for complications occurrence. 33 patients (15.2 %) suffered from local recurrence. Reoperations were mostly due to tumor recurrences, but also to hardware failures, wound dehiscence, hematomas and aortic dissection. Conclusion The rate of complication is higher in multisegmental resections and when double combined approach is performed. Reoperations display greater morbidity owing to dissection through scar/fibrosis from previous operations and possibly from RT. Careful treatment planning and, in the event of uncertainty, referral to a specialty center must be stressed. The high risk of complications should not discourage surgeons from performing en bloc resection when needed. Most of the patients who sustain complications benefit from the better local control resulting from en bloc resection.

IntroductionRadiotherapy (RT) is frequently applied as an adjuvant therapy during spinal tumors treatment. Metallic implants can interfere with RT planning and execution, as it is known that metallic implants produce a backscattering effect that can limit RT accuracy and their presence can be associated with unwanted dose increase. PEEK/carbon fiber implants are designed to reduce these problems but their application in the cervical spine is limited, due to the reduced number and types of implants, the screw dimensions and the absence of lateral mass screws. We propose a hybrid system made of carbon rods and screws coupled with subliminal polyester bands with titanium clamps. We designed this hybrid construct to enclose the cervical region in the area of instrumentation without limiting the application of postoperative radiotherapy.Materials and methodsSix patients in which the hybrid hardware was implanted were retrospectively examined. Data on demographics, intraoperative and postoperative events, tumor details and staging and cervical alignment were collected pre- and postoperatively.ResultsNo intraoperative complications occurred. En bloc resection was performed in two patients, while the remaining four received an intralesional resection. Three out of six patients received postoperative RT, without any alteration in its planning and administration.Discussion and conclusionsHybrid implants made of composite PEEK/carbon fiber screws and rods and sublaminar bands are a helpful solution for spinal reconstruction in the cervical and cervico-thoracic regions after spine tumor surgery. The implants do not produce artifacts at postoperative images, easing the planning and execution of postoperative radiotherapy.

IntroductionBiopsy of affected tissue is required for lymphoma diagnosis and to plan treatment. Open incisional biopsy is traditionally the method of choice. Nevertheless, it requires hospitalization, availability of an operating room, and sometimes general anesthesia, and it is associated with several drawbacks. Fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) can be potentially used to drive biopsy to the most metabolically active area within a lymph node or extranodal masses.MethodsA study of diagnostic accuracy was conducted to assess the performance of a PET-driven needle biopsy in patients with suspect active lymphoma.ResultsOverall, 99 procedures have been performed: three (3.0%) were interrupted because of pain but were successfully repeated in two cases. Median SUVmax of target lesions was 10.7. In 84/96 cases, the tissue was considered adequate to formulate a diagnosis (diagnostic yield of 87.5%) and to guide the following clinical decision. The target specimen was a lymph node in 60 cases and an extranodal site in 36. No serious adverse events occurred. The sensitivity of this procedure was 96%, with a specificity of 100%, a positive predictive value of 100%, and a negative predictive value of 75%.ConclusionPatients can benefit from a minimally invasive procedure which allows a timely and accurate diagnosis of lymphoma at onset or relapse.

Atlantoaxial rotatory subluxation/fixation (AARS/F) is a rare cause of torticollis in children. The aim of our study is to investigate all possible clinical and radiological prognostic factors in children with AARS/F. We retrospectively reviewed all cervical spine CT scans of children with AARS/F treated in our Hospital over the last 15 years. AARS/F was classified according to Fielding and Hawkins classification and C1-C2 rotation-degree was calculated. Moreover, two orthopedic surgeons reviewed all clinical reports of these children. All patients were conservatively treated (cervical traction/neck collar). An early recovery was considered in patients with complete clinical/radiological healing at 3 months follow-up, while a late recovery was considered in patients with disease persistence or relapse at 3 months follow-up or earlier. Fifty-five patients with diagnosis of AARS/F were included in the study (mean age = 8.5 years old – 25F, 30M). In 9/55 subjects (16.4%), a late recovery was observed. The presence of a concomitant infection or inflammation in the head and neck region (Grisel’s syndrome) was significantly associated with a late recovery (p < .001). Also, the type of AARS/F (p = .019), according to the Fielding and Hawkins classification, and C1-C2 rotation-degree (p = .027) were significantly correlated with the recovery time.Conclusion: In patients with AARS/F, the presence of a concomitant infection/inflammation in the head and neck region is the most important prognostic factor and it is associated with a late recovery. The Fielding and Hawkins classification and C1-C2 rotation-degree well correlate with patients’ recovery time.What is Known:• Atlantoaxial rotatory subluxation/fixation (AARS/F) is a rare cause of torticollis in children and CT is the most useful imaging tool for diagnosis and classification of AARS/F.• Conservative treatments are effective in the majority of pediatric patients with AARS/F.What is New:• The presence of a concomitant infection/inflammation in the head and neck region associated with AARS/F (Grisel’s syndrome) is the most important prognostic factor and it is associated with a late recovery.• C1-C2 rotation-degrees, as well as Fielding and Hawkins classification system, well correlate with patients’ recovery time.

Limited data exist on the clinical outcomes and inflammatory response of Enhanced Recovery After Surgery (ERAS) protocols in adolescent idiopathic scoliosis (AIS) patients undergoing posterior spinal fusion (PSF). This study evaluates ERAS’s impact by analyzing blood parameters and serum protein, surgical, and radiological parameters to assess safety, feasibility, and clinical outcomes. Between July 2021 and July 2022, 30 AIS patients underwent PSF with standardized pain management, high-dose tranexamic acid, early mobilization, and reduced opioid use. Blood tests and serum markers (IL-6, IL-1β, IL-1α, IL-10, TNF-α, IL-8, PGE2) were measured preoperatively and on postoperative day 2. Pain levels (VAS) were recorded preoperatively, on postoperative days 1 and 2, and at discharge. Results showed increased postoperative white blood cell counts, reduced hemoglobin and hematocrit, and elevated C-reactive protein levels. IL-6 was the only inflammatory marker significantly elevated, indicating a controlled inflammatory response. Pain peaked on day 1 but significantly decreased by discharge, confirming the effectiveness of multimodal analgesia. The average hospital stay was 6.97 ± 2.03 days, with low rehospitalization (6.66%) and manageable complications (20%). In conclusion, ERAS effectively optimizes AIS patient recovery, stabilizing pain, reducing complications, and improving perioperative care.

Laminectomy and posterior fixation are well-established surgical techniques to decompress nervous structures in case of lumbar spinal stenosis. While laminectomy is suspected to increase the instability of the spine, posterior fixation is associated with some complications such as adjacent segment degeneration. This study aimed to investigate how laminectomy and posterior fixation alter the biomechanics of the lumbar spine in terms of range of motion (ROM) and strains on the intervertebral discs. Twelve L2-S1 cadaveric spines were mechanically tested in flexion, extension, and lateral bending in the intact condition, after two-level laminectomy and after L4-S1 posterior fixation. The ROM of the spine segment was measured in each spine condition, and each loading configuration. The strain distribution on the surface of all the intervertebral discs was measured with Digital Image Correlation. Laminectomy significantly increased the ROM in flexion ( p  = 0.028) and lateral bending ( p  = 0.035). Posterior fixation decreased the ROM in all the loading configurations. Laminectomy did not significantly modify the strain distribution in the discs. Posterior fixation significantly increased the principal tensile and compressive strains in the disc adjacent the fixation both in flexion and in lateral bending. These findings can elucidate one of the clinical causes of the adjacent segment degeneration onset.

Background context Fast-track is an evidence-based multidisciplinary strategy for pre-, intra-, and postoperative management of patients during major surgery. To date, fast-track has not been recognized or accepted in all surgical areas, particularly in orthopedic spine surgery where it still represents a relatively new paradigm. Purpose The aim of this review was provided an evidenced-based assessment of specific interventions, measurement, and associated outcomes linked to enhanced recovery pathways in spine surgery field. Methods We conducted a systematic review in three databases from February 2012 to August 2022 to assess the pre-, intra-, and postoperative key elements and the clinical evidence of fast-track protocols as well as specific interventions and associated outcomes, in patients undergoing to spine surgery. Results We included 57 full-text articles of which most were retrospective. Most common fast-track elements included patient’s education, multimodal analgesia, thrombo- and antibiotic prophylaxis, tranexamic acid use, urinary catheter and drainage removal within 24 hours after surgery, and early mobilization and nutrition. All studies demonstrated that these interventions were able to reduce patients’ length of stay (LOS) and opioid use. Comparative studies between fast-track and non-fast-track protocols also showed improved pain scores without increasing complication or readmission rates, thus improving patient’s satisfaction and functional recovery. Conclusions According to the review results, fast-track seems to be a successful tool to reduce LOS, accelerate return of function, minimize postoperative pain, and save costs in spine surgery. However, current studies are mainly on degenerative spine diseases and largely restricted to retrospective studies with non-randomized data, thus multicenter randomized trials comparing fast-track outcomes and implementation are mandatory to confirm its benefit in spine surgery.
