Effect of Preoperative Nutritional Status on Postoperative Clinical Outcomes of Patients with Metastatic Spinal Tumors: Japan Association of Spine Surgeons with Ambition Multicenter Study.

Study Design: A multicenter prospective study.

Objective: To evaluate the effect of preoperative nutritional status, assessed using the Prognostic Nutritional Index (PNI), on clinical outcomes, including survival prognosis, postoperative complications, hospitalization duration, and functional prognosis, in patients with metastatic spinal tumors undergoing surgery.

Summary Of Background Data: Malnutrition is common in patients with cancer and is associated with poor clinical outcomes.

Degenerative Changes in the Disc, Facet Joint, and Paraspinal Muscle After Adolescent Idiopathic Scoliosis Surgery: A Five-Year MRI-Based Follow-Up.

Background and objectives This study aimed to comprehensively assess degenerative changes in the intervertebral disc, facet joint, and paraspinal muscle after adolescent idiopathic scoliosis surgery and to evaluate clinical outcomes at a five-year follow-up using magnetic resonance imaging (MRI). We hypothesized that the pattern of degeneration would differ based on the distal level of fusion. Materials and methods We retrospectively reviewed patients with adolescent idiopathic scoliosis who underwent surgery between 2006 and 2015.

Spinal Cord Müllerian-Like Cyst at the T12 Vertebral Level: A Case Report and Literature Review.

Müllerian cysts are rare developmental anomalies, typically found in the pelvis, with extrapelvic occurrences reported but spinal cord involvement being exceedingly rare. We present the first reported case of a Müllerian-like cyst located on the surface of the spinal cord at the T12 vertebral level. A 49-year-old woman presented with low back and right leg pain, including electric shock-like sensations during sneezing.

Intratumoral Flow Void Diameter as a Predictor of High Intraoperative Blood Loss in Palliative Excisional Surgery for Metastatic Spinal Tumors.

Massive intraoperative blood loss (IBL) is one of the major complications in metastatic spinal tumor surgery (MSTS), and understanding the predictors of this risk is essential. This study aimed to determine the impact of the intratumoral flow void (IFV) observed on standard magnetic resonance imaging (MRI) and its association with IBL in palliative surgery for metastatic spinal tumors. This retrospective analysis included 88 palliative excisional surgeries performed at a single hospital between 2010 and 2024.

Clinical Outcomes of Total En Bloc Spondylectomy for Previously Irradiated Spinal Metastases: A Retrospective Propensity Score-Matched Comparative Study.

This study aimed to investigate the clinical outcomes of total en bloc spondylectomy (TES) for spinal metastases previously treated with radiotherapy (RT). This study enrolled 142 patients who were divided into two groups: those with and those without an RT history. Forty-two patients were selected from each group through propensity score matching, and postoperative complications, local recurrence, and overall survival rates were compared.

The Impact of Frailty on Postoperative Complications in Total En Bloc Spondylectomy for Spinal Tumors.

Total en bloc spondylectomy (TES) is an effective treatment for spinal tumors. However, its complication rate is high, and the corresponding risk factors remain unclear. This study aimed to clarify the risk factors for postoperative complications after TES, including the patient's general condition, such as frailty and their levels of inflammatory biomarkers.

Needle tract seeding of a sclerosing epithelioid fibrosarcoma in a biopsy tract: a case report.

Background: A sclerosing epithelioid fibrosarcoma (SEF) is an uncommon tumor of the deep soft tissue. An SEF has been described as a low-grade tumor with high local recurrence and metastatic rates. Generally, in bone and soft tissue tumors, a resection of the biopsy route is recommended; however, there is limited evidence with respect to the dissemination of the tumor tissue during a needle biopsy.

Risk Factors for Progressive Spinal Sagittal Imbalance in the Short-Term Course after Total Hip Arthroplasty: A 3 Year Follow-Up Study of Female Patients.

Total hip arthroplasty (THA) for patients with hip osteoarthritis improves hip flexion contracture, subsequently improving spinal sagittal balance. However, in some cases, spinal sagittal imbalance develops in the course after THA, and its risk factors remain unknown. We aimed to investigate the risk factors of progressive spinal sagittal imbalance after THA.
