The bony callus

Injury, 1997
The bony callus was investigated by staining with the PAS and von Gieson techniques. The callus appeared to be composed of two adjoining but distinct types of bone. The birefringence observed in the periosteum and callus cartilage revealed different sized collagen fibres, each oriented perpendicularly to the long axis of the diaphysis.

Closed reduction with percutaneous Kirschner wire drill-and-pry for pediatric supracondylar humeral fractures with bony callus formation and delayed presentation

Injury, 2023
Supracondylar humeral fractures are the most common type of pediatric elbow fractures, and are primarily treated using closed reduction and percutaneous pinning. For patients who are treated ≥14 days after the injury, after callus formation has occurred, closed reduction is usually not possible.

Retroviral‐based gene therapy with cyclooxygenase‐2 promotes the union of bony callus tissues and accelerates fracture healing in the rat

The Journal of Gene Medicine, 2008
AbstractBackgroundAn in vivo gene therapy strategy was developed to accelerate bone fracture repair.MethodsDirect injection of a murine leukemia virus‐based vector targeted transgene expression to the proliferating periosteal cells arising shortly after fracture. Cyclooxygenase‐2 (Cox‐2) was selected because the transgene for its prostaglandin products

Yeast-Incorporated Gallium Promotes Fracture Healing by Increasing Callus Bony Area and Improving Trabecular Microstructure on Ovariectomized Osteopenic Rats

Biological Trace Element Research, 2010
The purpose of this study was to analyze the impact of yeast-incorporated gallium on fracture healing in ovariectomized osteopenic rats. Forty Wistar female rats used were divided into three groups: sham-operated rats (SHAM), ovariectomized (OVX) rats, and ovx rats treated with yeast-bound gallium (YG). A standardized fracture-healing model with stable

Acid Hydrolases and Bone Resorption in the Remodelling Phase of the Development of Bony Fracture Callus

Pathology, 1974
Summary Tibiae of young albino rats were fractured and the resultant bony callus was examined for acid hydrolase activity during the phase of resorption in vitro with and without parathyroid extract (PTE) and in vivo . In vivo three lysosomal enzymes, acid phosphatase, β -acetylglucosaminidase and β -galactosidase increased significantly ...

[Effect of radix Salviae miltiorrhizae on calcium, zinc, copper content in serum, callus and bony tissue in early stage of healing process in rat closed tibial fracture].

Zhongguo Zhong xi yi jie he za zhi Zhongguo Zhongxiyi jiehe zazhi = Chinese journal of integrated traditional and Western medicine, 1992
Changes of calcium, zinc, copper contents in serum, callus and bony tissue in the early stage of the healing process of rat closed tibial fracture, also the changes of them with radix Salviae miltiorrhizae (RSM) treatment were studied. It was found that calcium, zinc contents and Zn/Cu ratio increased significantly and the rise of serum copper content ...

[Experimental study of the possibilities of electrical stimulation of the development of bony callus (author's transl)].

Journal de chirurgie, 1977
The experiment was designed to study: 1) the reliability of an electrostimulator; 2) the possibility of internal fixation. The experimental animal was the dog, which was observed for 15 to 45 days. It appears possible to associate internal fixation and electrostimulation under certain conditions.
