6+ day, 16+ hour ago  (264+ words) Osteonecrosis of the femoral head (ONFH) is a progressive disorder that may lead to femoral head collapse and eventual total hip arthroplasty, particularly in relatively younger patients. Joint-preserving strategies remain of interest, and biologic augmentation has recently been explored as…...

3+ week, 1+ day ago  (203+ words) Polymethylmethacrylate (PMMA) gluteal augmentation has demonstrated favorable safety, efficacy, and cost-effectiveness when performed by experienced professionals. However, until 2023, available evidence remained limited by methodological bias and low levels of scientific rigor. A recent study has suggested that PMMA use for…...

3+ week, 3+ day ago  (178+ words) This technical report proposes a unified, system-level definition of the human core integrating anatomical, biomechanical, and functional perspectives. Despite the central role of core function in spinal stability, movement efficiency, and injury reduction, no comprehensive definition has been consistently adopted…...

1+ mon, 4+ day ago  (124+ words) Acute compartment syndrome (ACS) is a surgical emergency most commonly associated with trauma. A less common variant, acute exercise-induced compartment syndrome (AEICS), occurs without direct injury and is rarely seen in strength athletes. We report a case of a 50-year-old…...

1+ mon, 6+ day ago  (353+ words) Dietary supplements such as creatine, "-alanine, citrulline malate (CM), phosphatidic acid (PA), and "-ecdysterone are widely used to enhance exercise performance and muscle hypertrophy. Although generally considered safe, their combined use with high-intensity training may increase the risk of exertional rhabdomyolysis…...

1+ mon, 3+ week ago  (215+ words) This scoping review synthesized evidence on abdominal weight training (AWT), a non-invasive method for respiratory muscle rehabilitation that increases diaphragmatic load, to evaluate its clinical significance. We specifically summarized its effects on respiratory muscle strength, measured by maximal inspiratory pressure…...

1+ mon, 3+ week ago  (377+ words) Introduction Intramuscular gluteal augmentation with silicone implants is an established surgical approach aimed at improving implant coverage and contour stability. Conventional intramuscular dissection techniques involve limited visualization, which may affect pocket definition and intraoperative control. Direct-vision dissection represents a technical…...

1+ mon, 3+ week ago  (234+ words) Background and objectives This study compared the effects of M-cube wave and conventional low-frequency neuromuscular electrical stimulation (NMES) on the strength and thickness of quadriceps muscles in healthy young men using a within-subject design. Materials and methods This study included…...

2+ mon, 1+ week ago  (292+ words) Background and objective While sarcopenia is a recognized risk factor for hip fracture, the role of side-to-side lower-limb muscle mass asymmetry in determining fracture laterality remains unclear. This study aimed to investigate whether dual-energy X-ray absorptiometry (DXA)-derived lower-limb muscle…...
