The effect of polymethylmethacrylate augmentation on the primary stability of stand-alone implant construct versus posterior stabilization in oblique lumbar interbody fusion with osteoporotic bone quality- a finite element study.

Background Context: Oblique lumbar interbody fusion (OLIF) can provide an ideal minimally invasive solution for achieving spinal fusion in an older, more frail population where decreased bone quality can be a limiting factor. Stabilization can be achieved with bilateral pedicle screws (BPS), which require additional incisions and longer operative time. Alternatively, a novel self-anchoring stand-alone lateral plate system (SSA) can be used, where no additional incisions are required.

Complication Pattern of Sacral Primary Tumor Resection: A Study on the Risk Factors of Surgical Site Infection and Bowel or Bladder Dysfunction and Their Associations with Length of Hospital Stay.

Study Design: Retrospective open cohort study.

Purpose: The current study aimed to explore the pattern of complications after primary sacral tumor resection, to investigate the possible effect of several perioperative parameters on the development of complications, and to identify which complications are associated with the length of hospital stay (LOS).

Overview Of Literature: Primary sacral tumor (pST) resection is associated with a high complication rate.

Global Treatment Outcome after Surgical Site Infection in Elective Degenerative Lumbar Spinal Operations.

Surgical site infection (SSI) is a serious complication after routine lumbar spinal operations, and its effect on global treatment outcome (GTO) is less reported. The aim of the current study was to measure the impact of SSI on outcome, which was evaluated with patient reported outcome measures (PROMs) and patients' subjective judgment (GTO). A total of 910 patients underwent primary a single- or two-level lumbar decompression or instrumented fusion surgical procedure.

Risk factors for surgical site infection in elective routine degenerative lumbar surgeries.

Background Context: Surgical site infection (SSI) is one of the most serious complications of spine surgery. Its predisposing factors, especially in routine surgeries, are less reported. However, a number of patient- and procedure-related risk factors could be avoided or at least determined preoperatively.

[MEASURING THE FUNCTIONAL IMPAIRMENT OF THE LUMBAR SPINE].

Background And Purpose: The purpose of our study was to outline the Hungarian validation process of the Oswestry Disability Index, the Quebec Back Pain Disability Scale, the Roland-Morris Disability Questionnaire and the Core Outcome Measurement Index, as well as to draw up recommendations regarding their future applications.

Methods: The Hungarian versions were created after a cultural and linguistic adaptation. Next to the above-mentioned questionnaires, the questionnaire booklet used for validation also contained the WHOQoL-BREF general quality of life questionnaire and a pain measuring Visual Analog Scale.

Cross-cultural adaptation and validation of the Hungarian version of the Core Outcome Measures Index for the back (COMI Back).

Purpose: The Core Outcome Measure Index (COMI) is a short, multidimensional outcome instrument developed for the evaluation of patients with spinal conditions. The aim of this study was to produce a cross-culturally adapted and validated Hungarian version of the COMI Back questionnaire.

Methods: A cross-cultural adaptation of the COMI into Hungarian was carried out using established guidelines.

Validation of the Hungarian version of the Roland-Morris disability questionnaire.

Purpose: To create a cross-culturally adapted and clinically valid Hungarian version of the Roland-Morris Disability Questionnaire (RMQ).

Methods: After the translation and cross-cultural adaptation process, a total of 133 patients were included into the quality measurement study. Validity and reliability domains of the Hungarian RMQ were tested following the COSMIN guideline.

Primary Spinal Tumor Mortality Score (PSTMS): a novel scoring system for predicting poor survival.

Background Context: Although the surgical and oncological therapies of primary spinal tumors (PSTs) have changed significantly over the last few decades, the prognosis of this rare disease is still poor. The decision-making process in the multidisciplinary management is handicapped by the lack of large-scale population-based prognostic studies.

Purpose: The objective of the present study was to investigate preoperative factors associated with PST mortality and to develop a predictive scoring system of poor survival.
