[Clinical observation of phenytoin in promoting fracture healing]
Objective:
To observe the promoting effect of phenytoin on fracture healing.
Methods:
Fourty cases with close fractures of tibia and fibula were included and divided into two groups randomly: the experimental group was administrated with phenytoin and Chinese traditional drug-Jiegudan orally, while the control group was given Jiegudan only. Longitudinal percussion pain, clinical healing time of fracture, growth of calus in X-ray film were detected to evaluate the clinical result.
Results:
All the fractures were healed in 3 months. But the experimental group was superior to the control group in all indexes.
Conclusion:
Administration of phenytoin orally can markedly promote fracture healing.

01:27Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
01:25Role of Vitamins in Maintaining Bone Health
Vitamin A
Vitamin A is involved in the process of bone remodeling. Retinoic acid, the active metabolite of Vitamin A, has nuclear receptors in osteoblasts and osteoclasts, which are involved in bone remodeling.
Vitamin B12
Vitamin B12 acts as a cofactor during the formation of osteoblast-related proteins, such as osteocalcin. Vitamin B12 plays a role...
01:17Hormones and Bone Tissue
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...
