Abstract
Objective: To examine the effects of Jintiange on enhancing the healing of osteoporotic fractures in aged rats.
Methods: An osteoporotic fracture model of femur was established using 70 SD rats (aged > 12 months), which were randomly numbered and divided into an experimental group and a control group, each with an equal sample size (n = 35). The experimental group received Jintiange capsule ingredients via intragastric administration, while the control group received an equal volume of saline via the same method. X-ray examinations were conducted at the 4th and 12th weeks to evaluate fracture healing in the rats. After 12 weeks, micro-CT scanning was employed to assess the microstructure of the healthy femurs, and the parameters of the experimental and control groups were compared.
Results: After 4 weeks, the mean fracture healing scores were 0.78 ± 0.43 in the experimental group and 0.56 ± 0.51 in the control group. After 12 weeks, the mean scores were 1.50 ± 0.71 in the experimental group and 0.96 ± 0.68 in the control group. The scores in the experimental group were higher than those in the control group (P < 0.05). Micro-CT examination of the femurs showed an improvement trend in bone microarchitecture in the experimental group, indicated by increased bone volume fraction (BV/TV), trabecular number (Tb. N), and trabecular thickness (Tb. Th). However, these improvements were not statistically significant. A negative correlation with statistical significance was observed between trabecular separation (Tb. Sp) and fracture healing scores.
Conclusions: Jintiange may promote osteoporotic fracture healing in aged rats by enhancing bone microstructure.
期刊介绍:
Journal of Orthopaedic Surgery and Research is an open access journal that encompasses all aspects of clinical and basic research studies related to musculoskeletal issues.
Orthopaedic research is conducted at clinical and basic science levels. With the advancement of new technologies and the increasing expectation and demand from doctors and patients, we are witnessing an enormous growth in clinical orthopaedic research, particularly in the fields of traumatology, spinal surgery, joint replacement, sports medicine, musculoskeletal tumour management, hand microsurgery, foot and ankle surgery, paediatric orthopaedic, and orthopaedic rehabilitation. The involvement of basic science ranges from molecular, cellular, structural and functional perspectives to tissue engineering, gait analysis, automation and robotic surgery. Implant and biomaterial designs are new disciplines that complement clinical applications.
JOSR encourages the publication of multidisciplinary research with collaboration amongst clinicians and scientists from different disciplines, which will be the trend in the coming decades.
