Impaired bone healing not only causes chronic pain and disability for the patient, but also leads to considerable socioeconomic costs including healthcare costs and lost wages. When impaired healing occurs, it presents a frustrating problem for both the patient and the surgeon. Both parties desire a non-surgical option to stimulate bone healing. Bone stimulators present an attractive option to ...
Tendon-to-bone healing after rotator cuff repair surgery has a failure rate of 20%-94%. There has been a recent interest to determine the factors that act as determinants between successful and unsuccessful rotator cuff repair. Vitamin D level in patients is one of the factors that have been linked to bone and muscle proliferation and healing, and it may have an effect on tendon-to-bone healing...
Following bone fracture, the repair process starts with an inflammatory reaction at the fracture site. Fracture healing is disturbed when the initial inflammation is increased or prolonged, whereby, a balanced inflammatory response is anticipated to be crucial for fracture healing, because it may induce down-stream responses leading to tissue repair. However, the impact of the immune response o...
BACKGROUND AND PURPOSE Should blockade of TNF-α be avoided after orthopedic surgery? Healing of injuries in soft tissues and bone starts with a brief inflammatory phase. Modulation of inflammatory signaling might therefore interfere with healing. For example, Cox inhibitors impair healing in animal models of tendon, ligament, and bone injury, as well as in fracture patients. TNF-α is expressed ...
The quality of hematomas are crucial for successful early bone defect healing, as the structure of fibrin clots can significantly influence the infiltration of cells, necessary for bone regeneration, from adjacent tissues into the fibrin network. This study investigated if there were structural differences between hematomas from normal and delayed healing bone defects and whether such differenc...
The current strategies for healing bone defects are numerous and varied. At the core of each bone healing therapy is a biomimetic mechanism, which works to enhance bone growth. These range from porous scaffolds, bone mineral usage, collagen, and glycosaminoglycan substitutes to transplanted cell populations. Bone defects face a range of difficulty in their healing, given the composite of dense ...
Bone and cartilage healing are central to the practice of orthopedic surgery. Orthopaedic treatments should attempt to optimize the cells, scaffold, molecules, and blood supply required for healing. This chapter will describe the components required for successful healing, detail the role of each factor, and outline the complex interactions that occur during the healing processes of bone and ca...
Autologous bone is the most successful bone-grafting material; however, limited supply and donor site morbidity are problematic. Synthetic bone substitutes are effective, but healing is slow and unpredictable. Osseous wound healing may be enhanced if bone substitutes are combined with autologous bone marrow cells. To test this hypothesis, we created 40 calvarial defects in 20 12-week-old New Ze...
