Revision Surgery for Symptomatic Adjacent Segment Disc Degeneration after Initial Anterior Cervical Fusion: Is ROI-C Better than Plate-Cage Construct?

The optimal revision surgical strategy for patients who develop symptomatic adjacent segment disc degeneration (ASD) is controversial. The risks of intraoperative complications, especially the incidence of dysphagia, were relatively high for revision surgeries. This study was aimed at comparing the efficacy of revision surgery using a traditional plate-cage construct and zero-profile anchored spacer (ROI-C) device in treating symptomatic ASD after initial anterior cervical discectomy and fusion (ACDF) surgery. Forty-two patients who developed symptomatic ASD were retrospectively analyzed and classified into two groups (plate-cage group and ROI-C group). The clinical and radiological results were compared. We further evaluated the complication of dysphagia and dysphagia-related risk factors in these patients. The JOA and NDI scores, C2-7 lordotic angle, and intervertebral space height were significantly improved after revision surgery in both groups. The operative time and intraoperative blood loss both significantly decreased in the ROI-C group. The incidence of postoperative dysphagia was much lower in the ROI-C group than in the plate-cage group (18.75% vs. 57.69%; P = 0.01 ). The presence of dysphagia after initial surgery ( P = 0.003 ) and revision surgery type ( P = 0.01 ) was significantly related to the presence of dysphagia after revision surgery. These results indicated that both the plate-cage construct and ROI-C are effective in treating symptomatic ASD. However, compared with the traditional plate-cage construct, ROI-C with less operative time, less blood loss, and lower incidence of dysphagia is more suitable. Furthermore, ROI-C should preferably be used for patients who present with dysphagia after initial cervical surgery. This study will provide clinical guidance for spinal surgeons to choose the zero-profile device in treating specific and complicated cases, which will significantly improve the therapeutic efficacy of symptomatic adjacent segment degeneration.

Analysis of the gestational period and perinatal outcomes in women after surgical treatment of the cervix

Background. The purpose was to conduct a comparative analysis of the course of pregnancy and perinatal outcomes in women who underwent treatment of the cervix using various organ preserving surgical methods. Material and methods. We examined 250 women of reproductive age who underwent excision or ablative treatment of the cervix before pregnancy. The subjects were divided into five groups depending on the cervix treatment method. The study used general clinical examination protocols outlined in the regulations № 417 and № 676 issued by the Ministry of Health of Ukraine. The results. The most frequent complications of pregnancy in the patients with cervical surgery were: threatened abortion, threatened of preterm birth, anemia, low placentation, placental dysfunction, and low levels of amniotic fluid. Childbirth complications in women who underwent excision or ablation treatment of the cervix before pregnancy predominantly consisted of labor abnormalities, premature amniotic sac rupture, fetal distress, tears of the cervix and perineum. Among the complications of the postpartum period, there were isolated cases of subinvolution of the uterus, lochiometers, metroendometritis, and lactostasis. There were no cases of intrapartum and early neonatal mortality among the newborns. Conclusions. Given the high frequency of gestational and postpartum complications in women after organ-sparing surgical treatment of the cervix, it is necessary to choose the least harmful approach. The lowest incidence of complications during pregnancy, intra and postnatal periods was observed in the women who underwent laser vaporization and radio-wave ablation.

Radioiodine Refractory Follicular Thyroid Cancer and Surgery for Cervical Relapse

Compared to its more common counterpart papillary thyroid cancer (PTC), follicular thyroid cancer (FTC) has a less favorable outcome, due to its higher incidence of distant metastases and advanced stages at diagnosis. Despite radioiodine (RAI) avidity, metastatic FTC often progresses after radioiodine treatment (RAIT). We aimed at evaluating the indications and outcomes of surgery for cervical relapse of radioiodine refractory FTC. Patients receiving RAIT between 2005 and 2015 at the University Hospital of Cologne, Germany, were screened. Patients with FTC were identified. Demographics, clinic-pathologic characteristics, treatment, and outcome of patients diagnosed with RAI refractory FTC, who underwent cervical surgery in the course of disease, were analyzed. FTC accounted for 8.8% of all thyroid carcinomas undergoing RAIT. In 35.2% of FTC patients, disease persisted or recurred despite a cumulative mean RAI activity of 18.7 GBq ± 11.6 (follow-up 83.5 ± 56.7 months). Distant metastases were diagnosed in 75% of these patients, as bone (57.6%), lung (54.6%), and liver metastases (12.1%). Cervical relapse occurred in 63.6% of these patients and was treated in 57.1% with surgery with, and without, external beam radiation therapy (EBRT). Despite surgery and EBRT, in 75% of patients, cervical relapse recurred again. In conclusion, surgery for cervical radioiodine refractory FTC relapse is often performed in metastatic setting. With and without EBRT, cure is rare, although metastases can appear radioiodine avid. Early biological marker and systemic treatments for these patients are still needed.

Bibliometric and visualized analysis of the top 100 most-cited articles on anterior cervical surgery

Anterior cervical surgery (ACS) owes its development to various pioneering individuals whose revolutionary works form key advances and guide current medical decisions. This bibliometric study aimed to identify, analyse and visualize the main features of the most-cited papers in ACS. The citation count for the top 100 most-cited articles ranged from 148 to 1,197, and citations per year ranged from 3.1 to 89.8. The articles were published from 1958 to 2016, with the 2000s being the most active decade. There was an inverse correlation between the average citations per year since publication and article age. The oldest as well as most-cited two articles were both published in 1958 by Smith and Robinson, and Cloward, respectively. In their studies, the authors individually described the technique of anterior cervical discectomy with fusion (ACDF). The most popular keywords were: ‘fusion’ (22), ‘spine’ (20), ‘cervical spine’ (16), ‘complications’ (15), ‘arthrodesis’ (13), ‘interbody fusion’ (13), ‘bone morphogenetic protein’ (13), and ‘radiculopathy’ (12). ACDF was the most frequent surgical procedure (80%), while cervical disc arthroplasty is of gradual greater impact. The surgical techniques of ACDF have remained unaltered for over 60 years. More attempts are needed to promote its development. Cite this article: EFORT Open Rev 2021;6:1203-1213. DOI: 10.1302/2058-5241.6.210074

Human Papilloma Virus Vaccination: Focus on the Italian Situation

Human papilloma virus (HPV) is a viral agent whose transmission occurs mainly by sexual means. It causes different pathological conditions in both males and females, ranging from benign pathologies up to cancers. The introduction of vaccination has certainly had a major impact in terms of reducing the incidence of both HPV infections and diseases but in the European Union and the European Economic Area (EU/EEA) there are still about more than 13,000 deaths due to cervical cancer each year. To date in Europe and in Italy there are three vaccines available (bi-, tetra-, and nonvalent vaccines). The vaccination campaign started irregularly in Europe and Italy in 2007, with pre-adolescent girls as the primary target. Later, other cohorts were introduced such as 12-year-old boys, additional cohorts of >25-year-old women, women who already underwent cervical surgery and other subjects entitled to free vaccination. The COVID-19 pandemic has strongly impacted on public health services, particularly on vaccinations that, especially during the first pandemic phase, have been often delayed and/or canceled. The most affected vaccinations by the pandemic have been the non-mandatory ones, particularly those addressing the adolescent and adult population, such as immunization against papillomavirus. To date the achievement of the coverage target set by the Italian National Immunization Plan (NIP) has not yet been achieved. The aim of this work is to summarize the current situation in Italy and to discuss the strategies that have been implemented to increase overall vaccination coverage rates.

Clinical features and health-related quality of life in adult patients with mucopolysaccharidosis IVA: the Spanish experience

Background Mucopolysaccharidosis (MPS) IVA or Morquio A syndrome is a progressive and disabling disease characterized by a deficiency of the enzyme N-acetylgalactosamine-6-sulphate sulphatase. Its clinical presentation is very heterogeneous and poorly understood in adults. The aim of this study was to describe the clinical manifestations of MPS IVA in adult patients in Spain and to assess their health-related quality of life (HRQoL). Results Thirty-three patients from nine reference centres participated in the study. The median age was 32 (interquartile range [IQR]: 20.5–40.5) years. The phenotype was classical in 54.5% of patients, intermediate in 33.3% of patients, and non-classical in 12.1% of patients. The most common clinical manifestation was bone dysplasia, with a median height of 118 (IQR: 106–136) cm. Other frequent clinical manifestations were hearing loss (75.7%), ligamentous laxity (72.7%), odontoid dysplasia (69.7%), limb deformities that required orthopaedic aids (mainly hip dysplasia and genu valgus) (63.6%), and corneal clouding (60.6%). In addition, 36.0% of patients had obstructive sleep apnoea/hypopnoea syndrome and 33.3% needed non-invasive ventilation. Cervical surgery and varisation osteotomy were the most common surgical interventions (36.4% each). Almost 80% of patients had mobility problems and 36.4% used a wheelchair at all times. Furthermore, 87.9% needed help with self-care, 33.3% were fully dependent, and 78.8% had some degree of pain. HRQoL according to the health assessment questionnaire was 1.43 (IQR: 1.03–2.00) in patients with the non-classical phenotype, but 2.5 (IQR: 1.68–3.00) in those with the classical phenotype. Seven patients were initiated on enzyme replacement therapy (ERT), but two of them were lost to follow-up. Lung function improved in four patients and slightly worsened in one patient. The distance achieved in the six-minute walk test increased in the four patients who could perform it. HRQoL was better in patients treated with elosulfase alfa, with a median (IQR) of 1.75 (1.25–2.34) versus 2.25 (1.62–3.00) in patients not treated with ERT. Conclusions The study provides real-world data on patients with MPS IVA. Limited mobility, difficulties with self-care, dependence, and pain were common, together with poor HRQoL. The severity and heterogeneity of clinical manifestations require the combined efforts of multidisciplinary teams.

When can we expect global sagittal alignment to reach a stable value following cervical deformity surgery?

OBJECTIVE Cervical deformity (CD) is a complex condition with a clear impact on patient quality of life, which can be improved with surgical treatment. Previous study following thoracolumbar surgery demonstrated a spontaneous and maintained improvement in cervical alignment following lumbar pedicle subtraction osteotomy (PSO). In this study the authors aimed to investigate the complementary questions of whether cervical alignment induces a change in global alignment and whether this change stabilizes over time. METHODS To analyze spontaneous changes, this study included only patients with at least 5 levels remaining unfused following surgery. After data were obtained for the entire cohort, repeated-measures analyses were conducted between preoperative baseline and 3-month and 1-year follow-ups with a post hoc analysis and Bonferroni correction. A subanalysis of patients with 2-year follow-up was performed. RESULTS One-year follow-up data were available for 121 of 168 patients (72%), and 89 patients had at least 5 levels remaining unfused following surgery. Preoperatively there was a moderate anterior cervical alignment (C2–7, −7.7° [kyphosis]; T1 slope minus cervical lordosis, 37.1°; cervical sagittal vertebral axis [cSVA], 37 mm) combined with a posterior global alignment (SVA, −8 mm) with lumbar hyperextension (pelvic incidence [PI] minus lumbar lordosis [LL] mismatch [PI-LL], −0.6°). Patients underwent a significant correction of the cervical alignment (median ΔC2–7, 13.6°). Simultaneously, PI-LL, T1 pelvic angle (TPA), and SVA increased significantly (all p < 0.05) between baseline and 3-month and 1-year follow-ups. Post hoc analysis demonstrated that all of the changes occurred between baseline and 3 months. Subanalysis of patients with complete 2-year follow-up demonstrated similar results, with stable postoperative thoracolumbar alignment achieved at 3 months. CONCLUSIONS Correction of cervical malalignment can have a significant impact on thoracolumbar regional and global alignment. Peak relaxation of compensatory mechanisms is achieved by the 3-month follow-up and tends to remain stable. Subanalysis with 2-year data further supports this finding. These findings can help to identify when the results of cervical surgery on global alignment can be best evaluated.

Surgical treatment of dropped head syndrome secondary to fascioscapulohumeral muscle dystrophy: a case report

Fascioscapulohumeral muscular dystrophy is an uncommon hereditary myopathy which affects mainly the muscle of the face and upper limb girdle. We present a rare case with dropped head syndrome as the prominent manifestation of that disease and successfully treated by surgical management. It was a 25-year-old male patient with the chief complaint of neck pain and inability to maintain his horizontal gaze for long periods and as a result he had to quit his job as a shipper. His mother also had signs and symptoms of fascioscapulohumeral muscle dystrophy. Conservative treatment consisting of physical therapy and hard collar was the first attempt in order to reduce the neck pain and had limited result. We then performed a posterior cervical surgery including C2 to T2 instrumentation and kyphotic correction for the patient. The ten-month postop clinical and radiological results were satisfactory and the patient could return to his previous job. Dropped head syndrome with failed conservative treatment can be surgically treated after considering all clinical and radiographic factors.

Impact of Smoking On Surgical Outcomes For Patients Undergoing Cervical Surgery: A Systematic Review And Meta-Analysis

Objective: To determine whether smoking has adverse effects on outcomes following cervical surgery.Methods: We searched PubMed, Embase, Cochrane Library, and Web of Science through 13 July 2021 for cohort and case-control studies that investigated the effect of smoking on outcomes after cervical surgery. Two researchers independently screened the studies and extracted data according to the selection criteria.Results: The meta-analysis included 43 studies, including 27 case-control studies and 16 cohort studies, with 10020 patients. Pooled estimates showed that smoking was associated with higher rates of overall complications (odds ratio [OR]=2.00, 95% confidence interval [CI]: 1.63-2.44, p<0.00001), respiratory complications (OR=3.14, 95% CI: 1.94-5.08, p<0.00001), reoperation (OR=2.22, 95% CI: 1.41-3.49, p=0.005), dysphagia (OR=1.49, 95% CI: 1.07-2.07, p=0.02), wound infection (OR=3.19, 95% CI: 1.64-6.21, p=0.0006), axial neck pain (OR=1.97, 95% CI: 1.25-3.10, p=0.003), and a lower rate of fusion (OR=0.63, 95% CI: 0.49-0.81, p=0.0003). There were no significant differences between smoking and non-smoking groups in terms of operation time (mean difference [MD]=0.08, 95% CI: - 5.54 to 5.71, p=0.98), estimated blood loss (MD=-5.31, 95% CI: -148.83 to 139.22, p=0.94), length of hospital stay (MD=1.01, 95% CI: -2.17 to 4.20, p=0.53), Visual Analog Scale-neck pain (MD=-0.19, 95% CI: -1.19 to 0.81, p=0.71), Visual Analog Scale-arm pain (MD=-0.50, 95% CI: -1.53 to 0.53, p=0.34), Neck Disability Index (MD=11.46, 95% CI: -3.83 to 26.76, p=0.14), and Japanese Orthopaedic Association Scores (MD=-1.75, 95% CI: -5.27 to 1.78, p=0.33).Conclusions: Smokers appear to be more likely than non-smokers to suffer higher rates of overall complications, respiratory complications, reoperation, longer hospital stay, dysphagia, wound infection, axial neck pain, and a lower fusion rate following cervical surgery. It is essential to provide timely smoking cessation advice and explanation to patients before selective cervical surgery.
