How does spinopelvic alignment influence short-term clinical outcomes after lumbar fusion in patients with single-level degenerative spondylolisthesis?

Context: Studies on adult spinal deformity have shown spinopelvic malalignment results in worse outcomes. However, it is unclear if this relationship exists in patients with single-level degenerative spondylolisthesis (DS) receiving short-segment fusions.

Aims: To determine if spinopelvic alignment affects patient-reported outcome measures (PROMs) after posterior lumbar decompression and fusion (PLDF) with or without a transforaminal lumbar interbody fusion in patients with L4-5 DS.

The Effect of L5-S1 Degenerative Disc Disease on Outcomes of L4-L5 Fusion.

Study Design: Retrospective cohort study.

Objective: The aim was to investigate the clinical relevance of preoperative caudal adjacent segment degeneration (ASD) in patients undergoing isolated L4-5 fusion to determine a threshold of degeneration at which a primary L4-S1 fusion would be warranted.

Summary Of Background Data: Increased motion and biomechanical forces across the adjacent caudal segment in isolated L4-L5 fusion leads to concerns regarding the increased incidence of revision surgery because of the development of ASD.

Current Concepts and Advances of Three-Dimensional Printing in Reconstructive Musculoskeletal Oncology: A Systematic Review.

Three-dimensional printing has the potential to advance current surgical practice, by way of anatomical and pathological structure analysis and customized implant manufacturing. Applications for this technology include pre-operative planning, prosthesis customization, and bioprinting. A comprehensive literature review of PubMed, Embase, Cochrane Library, Scopus, and Web of Science databases was conducted to extract all studies adopting three-dimensional printing in the operative management of primary and metastatic musculoskeletal tumors.

Management of lower extremity orthopaedic injuries in epileptic patients: A systematic review.

Lower-extremity injuries may occur during seizures. There is a lack of standardized guidelines when diagnosing and planning perioperative care. Databases were systematically screened using predefined search terms.
