At present, the molecular mechanism underlying the protective effect of Ginsenoside Rb1 remains unclear. The present study was designed to investigate whether Ginsenoside Rb1 weakened the steroid‑induced avascular necrosis of the femoral head (SANFH) and to explore the possible mechanisms of the above effects. As a result, it was revealed that Ginsenoside Rb1 was protective against steroid‑induced avascular necrosis and inhibited serum osteocalcin in a rat model of SANFH. Ginsenoside Rb1 reduced inflammation, oxidative stress and bone cell apoptosis in a rat model of SANFH. Furthermore, Ginsenoside Rb1 attenuated trabecula parameters, total cholesterol and low density lipoprotein/high density lipoprotein in SANFH rat. Additionally, Ginsenoside Rb1 significantly reversed alkaline phosphatase and osteocalcin activities, vascular endothelial growth factor (VEGF) receptor, VEGF, Runt related transcription factor 2 (Runx2) and bone morphogenetic protein (BMP)‑2 protein expression in SANFH rat. Collectively, the present study demonstrated that Ginsenoside Rb1 attenuated SANFH through the VEGF/RUNX2/BMP‑2 signaling pathway.

Legg-Calvé-Perthes disease (LCPD), is a rare avascular osteonecrosis of the proximal femur usually occurring in children between 5 and 10 years of age. The cause of ischemia leading to necrosis of the femoral head remains unknown. The goal of surgical treatment for LCPD is to improve the containment of the femoral head to restore the function of the hip joint and prevent further damage to the femoral head leading to premature hip osteoarthritis.

Background: Valgus osteotomy is a femoral head-preserving surgery to treat femoral neck non-union in young, active patients. The traditional approach, however, causes medialisation of the femoral shaft during valgus correction, which alters femoral anatomy and complicates conversion to total hip arthroplasty if head osteosynthesis fails. This study aims to outline a novel surgical technique, medial opening wedge valgus intertrochanteric osteotomy (VITO), and evaluate its clinical and radiographic outcomes, focusing on restoring hip biomechanics and improving union rates.

Introduction: Costochondral grafting is well-known reconstructive option for the temporomandibular joint. In the upper extremity, non-vascularized costochondral grafts have been used for radial head reconstruction, for osteoarthritis of the trapeziometacarpal joint and proximal pole reconstruction of the scaphoid. Evidence suggests that vascularization of bone grafts lead to a higher union rate and a faster time to union.

Articular cartilage is an avascular tissue that allows for frictionless mobility of joints. Unfortunately, cartilage is incapable of self-repair and any damage leads to degradation in osteoarthritis (OA). Autologous chondrocyte implantation therapies are currently being used to treat focal cartilage defects caused by post-traumatic OA (PTOA).

Rationale: Slipped capital femoral epiphysis (SCFE) is a common adolescent hip disorder, but its association with hypothyroidism remains rare and poorly understood. This case highlights the importance of considering endocrine disorders, such as hypothyroidism, as potential risk factors in atypical SCFE presentations, particularly when trauma or other common etiologies are absent.
Patient Concerns: A 14-year-old boy presented with progressive, nontraumatic left hip pain that worsened over 6 weeks, eventually leading to complete immobility.
