Predicting postoperative imbalance in adult spinal deformity staged surgery using predictive thresholds.

Two-stage surgeries are increasingly used to minimize complications in adult spinal deformity (ASD) correction, yet the specific contributions of lateral lumbar interbody fusion (LLIF) and posterior column osteotomy/posterior spinal fusion (PCO/PSF) remain underexplored. This study evaluates their roles in deformity correction and establishes predictive thresholds for optimizing surgical planning. A total of 151 ASD patients (mean age 69.

Radioscapholunate Fusion Using a Volarly Placed Plate for Treating Post-Traumatic Radiocarpal Joint Arthritis after a Distal Radius Fracture - A Single-Centre Prospective Study.

There is currently no consensus regarding optimal treatment strategies for treating radiocarpal arthritis. The purpose of this prospective study was to compare preoperative and postoperative wrist range of motion (ROM), residual pain, grip and pinch strength, functional results and fusion rates after radioscapholunate (RSL) fusion using a volarly placed plate. This single-centre prospective study was conducted from January 2022 to December 2024.

High sensitivity and enhanced antibiotic stewardship of the BioFire Joint Infection Panel in acute, but not chronic, prosthetic joint infection of the knee.

The BioFire Joint Infection (JI) Panel is a multiplex polymerase chain reaction assay developed for rapid pathogen detection in synovial fluid, particularly for suspected prosthetic joint infections (PJI). However, its diagnostic sensitivity varies by clinical context and pathogen, and the impact of prior antibiotic exposure on sample quality and PJI stewardship remains unclear. This prospective study evaluated the diagnostic performance of the Investigational Use Only JI Panel versus conventional synovial fluid culture, using Musculoskeletal Infection Society criteria and symptom onset within 3 weeks to define acute PJI.

Novel post-cam endoskeleton-reinforced posterior-stabilized cement articulating spacer reduced the rate of mechanical complications in prosthetic knee infection.

Background: Posterior-stabilized cement articulating spacers (PS spacers) have superior knee scores and a greater range of motion in a two-stage exchange for chronic prosthetic knee infections (PKIs); however, mechanical complications are associated with the use of PS spacers. In the present study, we investigated a novel post-cam endoskeleton-reinforced PS spacer and its outcomes.

Methods: This single-surgeon retrospective cohort study included patients with chronic PKIs treated with PS spacers between 2015 and 2022.

Sesamoid Bone Reduction in Hallux Valgus: Comparing Radiological Outcomes of Hallux Valgus Following Distal Chevron Osteotomy and Modified McBride Procedure.

: Hallux valgus is a common forefoot disorder with hundreds of proposed management techniques. Distal chevron osteotomy with a modified McBride procedure has been traditionally recommended for mild hallux valgus because of its simple and less invasive nature with fewer complications, faster recovery, and reliable outcomes. In recent years, the indications for this procedure have expanded to include hallux valgus with severe deformities.

Effect of dorsal capsular imbrication on intraoperative DRUJ instability following arthroscopic TFCC repair surgery.

Background: To assess the clinical outcomes and identify the ideal indication for implementing dorsal distal radioulnar joint (DRUJ) capsular imbrication after triangular fibrocartilage complex (TFCC) repair in cases of DRUJ instability.

Methods: We conducted a retrospective study on patients who underwent arthroscopic TFCC repair between 2016 and 2021. Inclusion criteria comprised a symptomatic ulna fovea sign for over 6 months and dorsal DRUJ subluxation on magnetic resonance imaging.

Biomechanical analysis of plate versus K-wire fixation for metacarpal shaft fractures with wedge-shaped bone defects.

Background: Metacarpal shaft fracture is a common type of hand fracture. Numerous studies have explored fixing transverse fractures in the midshaft of the metacarpal bone. However, this section of the metacarpal bone is often susceptible to high-energy injury, resulting in comminuted fracture or bone loss.

Assessing Neurological Complications in Thoracic Three-Column Osteotomy: A Clinical Application of a Novel MRI-Based Classification Approach.

Study Design: Retrospective comparative study.

Objective: To investigate the occurrence of neurological complications in patients undergoing thoracic three-column osteotomy (3CO) utilizing an magnetic resonance imaging (MRI)-based classification that assesses spinal cord shape and the presence of cerebrospinal fluid at the curve apex and evaluate its prognostic capacity for postoperative neurological deficits.

Summary Of Background Data: Recent advancements in correction techniques have improved outcomes for severe spinal deformity patients undergoing 3CO.

What Are the Key Factors of Functional Outcomes in Patients with Spinopelvic Dissociation Treated with Triangular Osteosynthesis?

For patients with spinopelvic dissociation (SPD), triangular osteosynthesis is the current method for the fixation of the posterior pelvis. This study aimed to assess the recovery process and radiographic parameters associated with the functional outcomes in patients with SPD treated by triangular osteosynthesis. We collected data from 23 patients with SPD.

Midterm Results of Arthroscopy-Assisted "Tent Form" Triangular Fibrocartilage Complex Repair With Dorsal Distal Radioulnar Joint Capsule Imbrication for Posttraumatic Chronic Distal Radioulnar Joint Instability.

Purpose: To evaluate the outcomes of "tent form" triangular fibrocartilage complex (TFCC) repair combined with dorsal distal radioulnar joint (DRUJ) capsule imbrication for posttraumatic chronic DRUJ instability.
