Respiratory
The regulation of mineral ions in the serum is controlled mainly by parathyroid hormone, calcitonin, and vitamin D. Parathyroid hormone increases resorption of bone by stimulating osteoclastic activity to increase serum calcium. pain, local edema, hyperesthesia, stiffness, discoloration,vasomotor skin

Common problems include inadequate size and placement of intramedullary pins or insufficient number of plate-associated screws on each side of a fracture that allow fracture instability as well as excessive soft tissue disruption that delays or prevents revascularization (Fig. Bone grafts have been used for decades, with the use of autologous bone grafts being the gold standard.

Internal fixation stabilizes the bone fragments and ensures bone
Although bone can react to external stimuli or forces, it has limited methods of reaction: bone production, bone resorption, or a combination of production and resorption. Many variables are known to influence facture healing adversely. measured by inserting a tissue pressure-measuring device into the muscle
All fracture repair surgery may be viewed as a race between fracture healing and implant failure. kidneys, and other organs. Diaphyseal fractures of long bones may be described with the diaphysis divided into thirds; proximal, distal, or mid-diaphyseal. F). However, autologous bone grafts extend surgical time and are of limited supply in smaller animals, and there are potential.
Visceral injury causing damage to structures such as the brain, lung or bladder. Appropriate treatment of open wounds associated with fractures prevents further injury and bacterial contamination that can affect the outcome negatively. The gradual widening of the osteotomy gap, ideally 1mm per day, allows deposition of parallel columns of osteoid leading to formation of lamellar bone within these columns if sufficient stability is present (Fig. time in fracture treatment and frequently becomes frustrated with pro-longed

A large butterfly fragment is not incorporated into the fixation (white arrowhead). Many studies published in the last 6 years have added significantly to the knowledge base in the field of biologic bone healing techniques, with potential benefits for enhanced bone repair in humans and animals. Intramembranous ossification forms bone directly from osteoprogenitor cells and undifferentiated mesenchymal cells in the periosteum away from the fracture site without a cartilage precursor. Note the vertically oriented lamellar bone formation in the osteotomy site typical of distraction osteogenesis. incorporation. For extremity fractures in small animals, the joint(s) proximal and distal to the fracture should be included on the radiograph for assessment of possible joint involvement or preconditions that may alter the treatment or outcome. Most . decreased func-tion are the prime indications that a problem has developed. Woven, cancellous, and lamellar bone is found adjacent to the physis in the epiphyseal and metaphyseal regions; compact or cortical bone surrounds the marrow cavity in the diaphyseal region.1,2. The specific bone involved in the fracture can affect the outcome of fracture healing.

People who fracture their patella may have difficulty walking or straightening their leg. In the last two decades there have been major changes in the management of lower limb long bone fractures, where resources permit, surgical management of open . Vitamin D acts on the intestine to increase absorption of calcium and phosphorous and directly on bone by both mobilization of calcium and phosphorous from previously formed bone and promotion of maturation and mineralization of bone matrix. Radiography is ineffective in the differentiation and identification of soft tissue injuries, and although CT has better soft tissue contrast resolution than radiographs, neither provides the exquisite soft tissue images possible with MRI.55,61 Complications of fractures and their healing Semin Nucl Med. (osteoporosis) occur with persistence of CRPS. Bone differs from most other organs in that it retains the potential to regenerate and restore preinjury properties rather than heal by scar tissue of poorer quality than the original tissue.

Following mineralization of the osteoid, the osteoblasts become osteocytes. This represents a strong economic incentive to develop novel technologies to enhance bone healing.26 The incidence of nonunion fracture in dogs is approximately 3.4%27 with a range of 0% to 6%.28 The incidence of nonunion fracture in cats is 0.85%29 to 4.3%.13 The following brief summary is presented to recognize the importance and diversity of innovative biologic bone healing techniques that are being developed. with Dr. Perry Greene, MD.

In normal bone the activities of osteoblasts and osteoclasts are coordinated and occur in response to stress on the bone. Two orthogonal views of the area in question are essential for adequate evaluation of a potential fracture. The goal is to lengthen a bone that is too short as a result of premature growth cessation or to correct a misshapen bone.3,10, Many factors individually or in combination can have a marked effect on the success or failure of fracture healing. A bone fracture can be the result due to high force impact or stress, or trivial injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, bone cancer, or osteogenesis . from failure of the ends of a fractured boneto unite.

Processes that interfere with normal bone metabolism or physical trauma that stresses the bone beyond its structural capacity can result in fractures.

Damage to surrounding tissue, nerves or skin. The devitalized bone may collapse or reabsorb. The weakest zone is in the area of the hypertrophied cartilage cells; this is the most common area of physeal fracture following trauma.1-3 Bone healing is similar to the endochondral growth process.2,3 grafted, healing may take from 6 to 12 months or longer. may obscure the presence of arterial pulsation, and Doppler ultrasonography may

Location is the first descriptor used in describing a fracture and includes the bone involved and location in the bone. MRI is sensitive to changes in bone marrow that can aid in the identification of bone lesions that would not be otherwise detected. Purpose. In some patients oblique views are necessary to define or identify a subtle or complex fracture. The failure of bone healing results in enormous healthcare and socioeconomic costs. However, autologous bone grafts extend surgical time and are of limited supply in smaller animals, and there are potential complications at the harvest site.40,41 Bone allografts are available commercially and may be incorporated into fracture repair to provide osteoconductivity and additional support. bone healing. persistent discomfort and ab-normal movement at the fracture site.

Dealing with immediate life-threatening injuries takes precedence over imaging to look for fractures. Motion leads to degraded images in which important smaller fractures or fissures vital for planning reduction and stabilization of the fracture may be overlooked. Early complications
Physical examination is an essential first step in the evaluation of fractures and possible complicating factors. Compartment syndrome (or Volkmanns ischaemia). For extremity fractures in small animals, the joint(s) proximal and distal to the fracture should be included on the radiograph for assessment of possible joint involvement or preconditions that may alter the treatment or outcome. These include age and weight of the patient, quality of anatomic reduction, stability of fracture, extent of local blood supply, type of fracture, bone involved, presence of infection, iatrogenic interference, systemic diseases such as metabolic and endocrine diseases, pathologic fracture, corticosteroids, and use of nonsteroidal antiinflammatory drugs.

Diagnostic imaging provides valuable information concerning the location, type, complexity, and potential complications associated with fractures. (osteoporosis) occur with persistence of CRPS. The reduction of fracture fragments must be accurate and main-tained to ensure healing. Osteoinductive bone graft substitutes stimulate osteogenic differentiation of local undifferentiated cells and are especially useful for treating nonunion or compromised fractures. 16-4). gen-eral, fractures of flat bones (pelvis, scapula) heal rapidly.

Motion at the fracture site creates a micro-environment which causes healing to proceed through several . Various types of allografts are available and differ in their intended use, with the most common use being associated with repair of large defects and in spinal fusion.40 The development of endoprostheses may replace allograft use because of similar outcomes and easier availability.42 Other osteoconductive biomaterials are available widely and may be grouped into ceramic-based or polymer-based bone graft substitutes.
