Analysis of deformity and subsequent correction are the basis for many orthopaedic surgical procedures. In advanced cases of joint degeneration, arthroplasty may be the only available treatment option. Until recently, these analyses and preoperative surgical plans have been performed using standard radiographs, tracing paper, and/or plastic overlays. Numerous customized, commercially available, computer-based preoperative planning software programs have been introduced. The purposes of this study were to describe (1) the techniques used in deformity analysis and preoperative surgical planning using standard radiographs for joint arthroplasty and corrective osteotomies of the extremities, (2) the use of computed tomography (CT) scans to analyze rotational deformities in the presence and absence of joint prostheses and in planning corrective rotational osteotomies or revision joint replacement, and (3) the techniques for analyzing angular deformities of the spine. All these applications were performed with a widely available image analysis software.

Background: Severe rigid neurologic equinovarus foot (NEVF) deformity, though rare, significantly limits transfers and orthotic use in pediatric patients with neurological disorders. Standard treatments like arthrodesis or talectomy are highly invasive, especially in young patients. This study assesses the mid-term outcomes of a talar neck trapezoidal osteotomy (TNTO) to correct severe NEVF in non-ambulatory patients.

Background And Objective: To determine whether there is disproportionate reporting of hepatobiliary disorders in the United States (US) FDA Adverse Event Reporting System (FAERS) for individuals prescribed ketamine or esketamine.
Design: We identified Medical Dictionary for Regulatory Activities (MedDRA) terms in the FAERS related to hepatobiliary disorders.
Main Measures: Formulations of ketamine and esketamine were evaluated for the proportionality of reporting for each hepatobiliary disorder parameter using the reporting odds ratio (ROR).

Objective: The study aimed to investigate the impact of varying thyroid function statuses on clinical and laboratory indicators in patients with systemic lupus erythematosus (SLE).
Methods: A retrospective analysis was conducted on 258 patients with SLE, who were stratified according to thyroid function, renal involvement, and disease activity. The predictive value of thyroid hormones was evaluated using a receiver operating characteristic (ROC) curve.

Aflatoxins harm the reproductive system and gamete development in animals. Primordial germ cells (PGCs) in chickens, as ancestral cells of gametes, are essential for genetic transmission, yet the impact and mechanisms of aflatoxins on them remain elusive. This study systematically investigated the effects of aflatoxin B1 (AFB1) on chicken PGCs and their potential mechanisms using an in vitro culture model.

Adolescent idiopathic scoliosis (AIS), which typically occurs in patients between the ages of 10 and 18, can be caused by a variety of reasons, and no definitive cause has been found. Early diagnosis of AIS or timely recognition of progression is crucial for the prevention of spinal deformity and the reduction of the risk of surgery or postponement. However, it remains a significant challenge.
