RESUMEN

PURPOSE: This study aims to conduct a systematic review of the literature comparing pre-operative, intraoperative, and post-operative characteristics between adolescent idiopathic scoliosis (AIS) and young adult idiopathic scoliosis (YAdIS) patients. METHODS: Following PRISMA guidelines, we conducted a search of the PubMed/Medline, EMBASE, and Cochrane Central databases to identify full-text articles in the English-language literature. Our inclusion criteria were studies that compared preoperative, intraoperative, and postoperative characteristics between AIS and YAdIS patients. We performed a meta-analysis reporting mean difference (MD) for continuous variables and Odds ratios (ORs) to assess differences in postoperative complications. RESULTS: Seven studies consisting of 1562 patients were included in the meta-analysis. The AIS group exhibited less intraoperative bleeding and shorter surgical procedures, with a mean difference between groups of 122.3 ml (95% CI 46.2-198.4, p = 0.002) and 28.7 min (95% CI 6.5-50.8, p = 0.01), respectively. Although the preoperative Cobb angle did not differ between groups (p = 0.65), patients with AIS achieved superior postoperative deformity correction, with a mean difference of 7.3% between groups, MD - 7.3 (95% CI - 9.7, - 4.8, p < 0.00001), and lower postoperative Cobb angles of the major curve, MD 4.2 (95% CI 3.1, 5.3, p < 0.00001). YAdIS patients were fused, on average, 0.2 more vertebral levels than AIS patients, MD 0.2 (95% CI 0.01, 0.5, p = 0.04). AIS patients experienced a significantly shorter length of stay after the surgical procedure, with an MD of 0.8 days (95% CI 0.1, 1.6, p = 0.02). No significant difference was found between groups in terms of complications (p = 0.19). CONCLUSIONS: YAdIS should be regarded as a distinct surgical entity, characterized by increased bleeding, longer surgical duration, greater deformity correction challenges, and the need for fusion of additional vertebral levels compared to AIS. Surgeons should be mindful of these differences and discuss them with patients and their families, especially in cases where the correction of the AIS deformity is delayed and there is a high risk of progression after skeletal maturity. Further research is needed to explore alternative surgical techniques and enhance outcomes for YAdIS patients.

RESUMEN

OBJECTIVE: The aging global population presents an increasing challenge for spine surgeons. Advancements in spine surgery, including minimally invasive techniques, have broadened treatment options, potentially benefiting older patients. This study aims to explore the clinical outcomes of spine surgery in septuagenarians and octogenarians. METHODS: This retrospective analysis, conducted at a US tertiary center, included patients aged 70 and older who underwent elective spine surgery for degenerative conditions. Data included the Charlson Comorbidity Index (CCI), ASA classification, surgical procedures, intraoperative and postoperative complications, and reoperation rates. The objective of this study was to describe the outcomes of our cohort of older patients and discern whether differences existed between septuagenarians and octogenarians. RESULTS: Among the 120 patients meeting the inclusion criteria, there were no significant differences in preoperative factors between the age groups (P > 0.05). Notably, the septuagenarian group had a higher average number of fused levels (2.36 vs. 0.38, P = 0.001), while the octogenarian group underwent a higher proportion of minimally invasive procedures (P = 0.012), resulting in lower overall bleeding in the oldest group(P < 0.001). Mobility outcomes were more favorable in septuagenarians, whereas octogenarians tended to maintain or experience a decline in mobility(P = 0.012). A total of 6 (5%) intraoperative complications and 12 (10%) postoperative complications were documented, with no statistically significant differences observed between the groups. CONCLUSIONS: This case series demonstrates that septuagenarians and octogenarians can achieve favorable clinical outcomes with elective spine surgery. Spine surgeons should be well-versed in the clinical and surgical care of older adults, providing optimal management that considers their increased comorbidity burden and heightened fragility.

RESUMEN

OBJECTIVE: Selecting C2 versus C3 or C4 (i.e., C3/C4) as the rostral anchoring level in long-segment cervical fusions is a common clinical conundrum. The data regarding proximal failure in long constructs of the cervical spine is scarce. The objective of this study was to systematically review the published literature and perform a meta-analysis of the incidence for proximal adjacent-segment disease (ASD) in the context of long cervical fusions and cervicothoracic fusions ending in C2 versus those ending in the subaxial spine (C3 or C4). METHODS: Using the PRISMA guidelines, the authors performed a search of the PubMed/MEDLINE, Embase/Ovid, and Cochrane Central databases to identify all full-text articles in the English-language literature with the following inclusion criteria: 1) studies including patients with the upper instrumented vertebra (UIV) at C2 versus C3/C4; 2) patients undergoing ≥ 3-level posterior cervical fusion; and 3) indication for surgery of degenerative disc disease, cervical spondylotic myelopathy, or cervical deformity. Studies that were not published in the English language, case reports, review articles, letters to the editor, and meeting abstracts were excluded. A meta-analysis was conducted using a fixed-effects model when I2 values were below 70%. Conversely, when I2 values were equal to or greater than 70%, a random-effects model was used. A funnel plot was used to assess the presence of publication bias. RESULTS: Seven studies consisting of 1215 patients were included in the meta-analysis. There were 403 (32.8%) patients in the C2 UIV group and 812 (67.2%) patients in the C3/C4 UIV group. When the 7 studies were analyzed, the overall rate of reoperation was comparable between the C2 (9.2%) and C3/C4 (9.4%) UIV groups (p = 0.93) but the rate of surgical ASD due to proximal pathology was 1.2% and 3%, respectively (OR 0.36, 95% CI 0.15-0.86; p = 0.02). When comparing between groups, no statistical difference was found regarding the rate of reoperation due to distal pathology or surgical infection. CONCLUSIONS: Long-segment cervical or cervicothoracic constructs that anchor into C2 may have similar complication rates but lower revision rates for proximal ASD than constructs that anchor into the subaxial spine.

RESUMEN

BACKGROUND: The evidence for instrumented fusion in the setting of degenerative, traumatic, or congenital deformity is well established. Data on fusion indications in intradural spinal tumors (IDST) are scarce and reduced to retrospective studies. The objective of this work is to systematically review the published literature since 2015 and analyze the change of practice patterns for stabilization and fusion after intradural tumor resection in adults. METHODS: A systematic literature review was performed via PubMed with the terms: "intradural spinal tumors", "intramedullary spinal tumors", and "intraspinal tumors". The analysis was limited to adult patients with IDST and studies with more than 10 patients. Data on the proportion of patients who underwent instrumentation and had postoperative deformity was pooled in a meta-analysis. RESULTS: A total of 1073 articles were identified and 47 papers were selected. All the studies were retrospective series and a total of 2473 patients were included. The follow-up ranged from 1 to 96 months, the pooled spinal fixation rate was 6% (95% CI 4.5%-7.6%), the pooled laminoplasty rate was 14.4% (95% CI 5.9%-23%), the pooled rate of postoperative deformity or malalignment in patients with a follow up of at least 6 months was 2.1% (95% CI 1.2%-3%) and just 7 patients were reoperated due to progressive deformity. CONCLUSIONS: Based on existing evidence, the rate of fusion during resection of intradural spinal tumors is low. Prophylactic fixation is often unnecessary and only indicated in unique cases that require extensive bony resection.

RESUMEN

BACKGROUND Intussusception is a rare pathological entity in adults and remains a diagnostic challenge for clinicians, as it shares many clinical signs and symptoms with other morbid conditions (including appendicitis, abdominal hernias, colic, volvulus, and Meckel diverticulum). High clinical suspicion and use of appropriate imaging techniques are essential for early diagnosis and treatment of intussusception. Surgical intervention is the treatment of choice in cases of sustained and persistent invagination. CASE REPORT We present the case of a 65-year-old woman with a medical history of Crohn's disease, diabetes mellitus type II, hypertension, and rheumatoid arthritis. She was hospitalized for diarrhea, fatigue, and anemia. Computerized tomography of the abdomen and a colonoscopy revealed telescoping of the ileum, ileocecal valve, and part of the ascending colon inside the terminal segment of the ascending colon. The antegrade ileocolic intussusception was treated by performing a right hemicolectomy. The pathologic examination of the excised intestine showed mucosal lesions compatible with Crohn's disease, an inflammatory fibroid polyp at the terminal section of the ileum, and a low-grade appendiceal mucinous neoplasm. CONCLUSIONS Regardless of the etiology, when the normal motility of the intestine is altered, it can lead to invagination. Although intussusception is rare, it must always be part of the differential diagnosis for a patient presenting with constant abdominal pain.

RESUMEN

INTRODUCTION: Mesenchymal stem cells (MSCs) can be obtained from a wide variety of tissues for bone tissue engineering such as bone marrow, adipose, birth-associated, peripheral blood, periosteum, dental and muscle. MSCs from human fetal bone marrow and embryonic stem cells (ESCs) are also promising cell sources. AREAS COVERED: In vitro, in vivo and clinical evidence was collected using MEDLINE® (1950 to January 2014), EMBASE (1980 to January 2014) and Google Scholar (1980 to January 2014) databases. EXPERT OPINION: Enhanced results have been found when combining bone marrow-derived mesenchymal stem cells (BMMSCs) with recently developed scaffolds such as glass ceramics and starch-based polymeric scaffolds. Preclinical studies investigating adipose tissue-derived stem cells and umbilical cord tissue-derived stem cells suggest that they are likely to become promising alternatives. Stem cells derived from periosteum and dental tissues such as the periodontal ligament have an osteogenic potential similar to BMMSCs. Stem cells from human fetal bone marrow have demonstrated superior proliferation and osteogenic differentiation than perinatal and postnatal tissues. Despite ethical concerns and potential for teratoma formation, developments have also been made for the use of ESCs in terms of culture and ideal scaffold.
