[Clinical application of anatomical locking plate in treatment of Rockwood type - patella fractures].

Objective: To investigate the effectiveness of anatomical locking plate in the treatment of Rockwood type Ⅰ-Ⅲ patella fractures.

Methods: The clinical data of 16 patients with patella fractures who were admitted between November 2021 and January 2023 and met the selection criteria was retrospectively analyzed. There were 14 males and 2 females, with an average age of 44.

Diagnostic value of combined serum marker changes and quantitative MRI evaluation of cartilage volume of tibial plateau in a surgically-induced osteoarthritis dog model.

Objective To evaluate the combined diagnostic value of two serum osteoarthritis (OA) markers and quantitative magnetic resonance imaging (MRI) evaluation of the cartilage volume of the tibial plateau in a canine model of experimental OA. Methods A total of 18 male Beagle dogs were used in this longitudinal study. OA was surgically induced via anterior cruciate ligament transection (ACLT) of the right knee in 10 dogs.

Therapeutic effect of osteogenically induced adipose derived stem cells on vascular deprivation-induced osteonecrosis of the femoral head in rabbits.

Objective: To explore the therapeutic effect of osteogenically induced adipose-derived stem cells (ADSCs) on vascular deprivation-induced osteonecrosis of the femoral head (ONFH) in rabbit model.

Methods: Vascular deprivation-induced ONFH was established by intramuscular injection of methylpre- dnisolone, and vascular occlusion of the capital femoral epiphysis by electrocoagulation in adult New Zealand white rabbits. Eight weeks after the establishment of vascular deprivation-induced ONFH, animals were randomly divided into three equal groups.

Can bisphenol A diglycidyl ether (BADGE) administration prevent steroid-induced femoral head osteonecrosis in the early stage?

Steroid-induced osteonecrosis of the femoral head (ONFH) is associated with increase of intraosseous pressure caused by elevating of adipogenesis and fat cell hypertrophy in the bone marrow, which subsequently decreases the blood flow in the femoral head and finally resulting in bone ischemia. The early femoral head-preserving method has mainly focused on the conventional core decompression procedure. However, it only achieves a slight decrease in intra-medullary pressure with limited clinical outcome.
