Within 7 14 days granulation tissue is formed between the fragments leading to vascularization of the hematoma.

Www mesothelioma com scholarship. Conclusion fracture and wound healing is influenced by many variables including mechanical stability electrical environment biochemical factors and blood flow etc our ability to enhance fracture and wound healing will increase as we better understand the interaction between these variables. A fracture of the distal radius is commonly referred to as a broken wrist. A spiral fracture in the upper limb.

The periosteum and endosteum are the two major sources. Fracture healing is unique in that there is reconstruction of the original tissue rather than healing with scar formation as in other tissues stages of fracture healing inflammatory stage fracture causes soft tissue injury and ruptured vessels formation o.

Within 48 hours chemotactic signaling mechanisms attract the inflammatory cells necessary to promote the healing process. Introductionbr fracture is a break in the structural continuity of bone or periosteumbr the healing of fracture is in many ways similiar to the healing in soft tissue wounds except that the end result is. Fracture healing involves a complex and sequential set of events to restore injured bone to pre fracture condition.

The mechanical stability governs the mechanical strain. Of orthopaedicsbr nims medical college hospitalbr 2. The technique of perkins method is described and the results reported in 50 cases.

The fracture healing process begins right from the time of injury and proceeds at a constant rate with slight variations depending on age of patient and location of injury. For normal fracture healing. Nutrient artery medullary arteries supplies the marrow and inner 23 of diaphysial cortex.

Perkins classification of fracture healing time in weeks for the fracture to unite and become fully healed 25. Fracture stability dictates the type of healing that will occur. Stem cells are crucial to the fracture repair process.

All patients had at least 120 degrees of flexion of the knee when traction was discontinued and 47. The treatment of fractures of the femoral shaft by traction may delay union and produce stiffness of the knee. The fracture hematoma initiates the healing response.
