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.

Callus Formation After Bony Resection in Diabetic Patients

The Journal of Bone and Joint Surgery-American Volume, 2001
To The Editor: Regarding the article entitled “Factors Associated with Bone Regrowth Following Diabetes-Related Partial Amputation of the Foot” (81-A: 1561-1573, Nov. 1999), by Armstrong et al., I would like to offer a few suggestions. The patients in this study were characterized by the presence of autonomic neuropathy. According to several authors,

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 ...
