BACKGROUND. Disorders of the articular surfaces are associated with impaired quality of joint motion and joint play. Crepitations are the hallmark clinical sign. This paper aims to present the possibilities of using vibroacoustic signal analysis in assessing the function of articular surfaces in the course of disorders of the knee and shoulder. MATERIAL AND METHODS. The study involved 30 people, 10 for each of the following disorders: patellar chondromalacia (Ch), meniscal tears (Mc), and degenerative changes of the glenohumeral joint (GH). A control group (K1-K3) was matched to each dysfunctional group. 6-second vibroacoustic signals (VAG) were recorded during motion in particular joints. The resulting time series were filtered (50-1000 Hz) and the following parameters were calculated: variance-mean-square (VMS), the mean of the four lowest and four highest values (R4) and the total spectral power density in the 50-250 Hz (P1) and 250-450 Hz (P2) ranges. RESULTS. Depending on the type of disorder, VAG signals in the dysfunctional groups were characterized by higher variability, amplitude and frequency than was the case in the control groups. This is reflected in the values of all parameters (VMS, R4, P1, P2), which were significantly higher in the Ch, Mc and GH groups compared to K1-K3. CONCLUSIONS. 1. Vibroarthrography can be a useful tool for accurate and objective assessment of the quality of joint motion. 2. The non-invasive nature of vibroarthrography allows the use of this method to monitor the effects of the treatment of joint structures.

Background: Cartilage defects in the knee joint are areas of damage and wear to the cartilage that normally covers and protects the ends of bones. These defects occur due to sudden injuries, such as trauma or sports accidents, or due to chronic conditions, such as osteoarthritis. Cartilage acts as a shock absorber (cushion absorber), reducing the impact of mechanical stress on the joints, which helps prevent bone damage during movement.

Background: One-hole split endoscopy (OSE) is a novel endoscopic technique that offers some advantages in spinal surgery. However, without a clear understanding of the safe zone for OSE, surgeons risk injuring nerve roots during the procedure. This study aimed to measure the safe distances among critical bone markers, the intervertebral space and nerve roots between 1-degree degenerative lumbar spondylolisthesis (DLS) and non-DLS at the L segment in patients via three-dimensional reconstruction and to compare the differences in relevant safety distances between the two groups.

There is currently no cure or disease-modifying treatment for post-traumatic osteoarthritis (PTOA). This study aims to assess the efficacy of dimethyl fumarate (DMF), a US-FDA approved drug for multiple sclerosis, as a treatment for PTOA. PTOA was induced in male Lewis rats by medial meniscal transection (MMT) surgery, and DMF was intra-articularly administered once, one week following surgery.

This study presents the optimization of the friction stir welding (FSW) process using polynomial regression to predict the maximum tensile load (MTL) of welded joints. The experimental design included varying spindle speeds from 600 to 2200 rpm and welding speeds from 100 to 350 mm/min over 28 experimental points. The resulting MTL values ranged from 1912 to 15,336 N.

Fusion-welded austenitic stainless steel (ASS) was predominantly employed to manufacture dry storage canisters (DSCs) for the storage applications of spent nuclear fuel (SNF). However, the ASS weld joints are prone to chloride-induced stress corrosion cracking (CISCC), a critical safety issue in the nuclear industry. DSCs were exposed to a chloride-rich environment during storage, creating CISCC precursors.
