Chronic Osteomyelitis Research Paper

These include; where the tumor is, how big it is, if it has spread to any other parts or areas of the body, the patients weight and age, if there is a break in the bone caused by the tumor, and if the patient has any genetic diseases. After those issues have been addressed treatment is able to be determined (Osteosarcoma and MFH of Bone Treatment). There are also two broad categories of Osteosarcoma and they are low grade and high grade. During low grade the common treatment is wide excision only and chemotherapy is not usually recommended before or after the surgery. If it is high grade Osteosarcoma then chemotherapy is usually performed for 2-3 cycles before surgery and 3-4 cycles after surgery (Choy, E.). Chemotherapy is not the only treatment for Osteosarcoma. The three things that are usually combined and used are; surgery, chemotherapy, and radiation therapy. During surgery, the surgeon goes in and removes the tumor and any surrounding tissues so that area is “free of disease”. Another surgery procedure that is performed is radioplasty, which is where the ankle joint is used as a replacement for the knee joint after an amputation. After surgery, a pathologist looks at the amputated bone to see how many tumors have died due to the chemotherapy. This helps to decide on what antibiotics to start using and if chemotherapy should be continued. Radiation therapy is not

Osteomyelitis is a medical term used for a bone infection which is usually caused by

A) Bacteria commonly cause Osteomyelitis, but fungi and germs can also be the cause of the infection. Bacteria can spread to bone through infected skin, tendons, or muscles next to bone. Also, It may start in another region in the body and flow through the blood to the bone. Osteomyelitis can also infect people after they have bone surgery where metal rods or plates are put inside a bone. (http://www.nlm.nih.gov/medlineplus/ency/article/000437.htm)

In the 2015 study conducted by Popov, a 61 year old male was diagnosed after arterial surgery. The patient came in complaining of pain. This is common along with inflammation and a red, hot feeling in the area. The person may also experience a fever. In other cases, some people have been infected after surgery. It is more likely to occur in an individual that has a compromised immune system. In one instance of the infection, the person contracted on the forearm around the area of what was constant drug use. The source would have been a dirty needle. Another individual contracted the bacterium on the upper leg. This was suspected to be the site of an insulin injection for a woman with diabetes.

Response/Recommendation: There are no studies focusing on the strategies to minimize the risk of recurrent infection of a previously infected joint during reconstructive procedures. However, based on the available literature on surgical site infection (SSI) and prosthetic joint infection (PJI) prevention, the strategies below can be recommended:

Since the concept of wound bed preparation arose (Schultz et al, 2003), striving to achieve a wound environment that is conducive to healing has become increasingly important (Dowsett, 2002). Debridement plays a crucial role in this concept. Eliminating non viable tissue from wound bed which acts as a significant barrier to wound repair if not removed (Dowsett and Claxton, 2006). The presence of necrotic tissue in wound has known deleterious effects including sepsis and delayed healing. Debridement is therefore an essential adjuct in treatment of non healing ulcer (Anu, Emane and Morris, 2001). Debridement is the removal of devitalized or contaminated tissue within or adjacent to wound until surrounding tissue is exposed (Smith, 2002).According to International Diabetic Federation (2004), removal of dead or devitalized tissue is paramount for effective wound care of DFUs. Frykberg et al, (2006) advocate regular debridement to remove necrotic tissue and reduce burden in order to expedite wound healing. Although it is widely accepted that debridement may be necessary for optimal wound healing for DFUs, evidence from randomized trials relating to the effectiveness of its different method is lacking and method of measuring its effectiveness are poorly developed (Haycock and Chadwick, 2012). Debridement has always been

In 1992, CDC revised its definition of ‘wound infection’, by creating the definition, ‘surgical site infection’, to prevent the confusion between the infection of a surgical incision and the infection of a traumatic wound (Horan et al 1992). A precise definition of surgical site infection is vital for personnel measuring infection rates (WHO 2009). The definitions of surgical site infection may vary between research studies but are commonly based on those described by the Centers for Disease Control and Prevention although other valid measures have been used (NICE 2008). The CDC definition describes three levels of SSI:

The second patient, a 30 year old female, experienced pain and stiffness in her left hip/lower limb. This started in this patient at eight months old and has continued ever since. After doing a radiograph and a CT they found that there was cortical hyperostosis that involved the left iliac bone and extended into the left femur. It also involved the knee crossing the intervening joint, the left tibia, and the tarsal bones. Visually they saw osteoarthritis changes occurring with the patient's hip joint. Additionally they found bone islands located on her left femur, tibia, and patella. Bone islands benign bone tumors that are mostly encountered as an incidental and asymptomatic finding; they are suggestive of coexisting osteopoikilosis.

The patient is an elderly female 84 years of age was transferred to the ED from the primary care doctor's office because of increased confusion as well as increasing frequency of falls. There is a feeling the patient has a urinary tract infection. In the past the patient is known to have ESBL with proteus in the urine. She is growing Proteus again. On this admission the sensitivities are not yet available. she is also having frequent increased falls at home. There is also some suggestion that she might have had a syncopal episode. Her medical history is significant for hypertension, hypothyroidism, dementia, chronic osteomyelitis, she does have a pacemaker in place and as previously stated, and the urine is ready growing proteus within

(13) Interleukins are therefore key mediators in the inflammatory process. (14) Surgical injury triggers an acute IR, in which numerous cytokines and growth factors serve as mediators, which can promote tissue regeneration or repair. At this stage, high levels of pro-inflammatory cytokines with bone resorption capacity, such as interleukin-12 (IL-12), can cause undesirable bone resorption, leading to functional and aesthetic impairment. The cellular sources of IL-12 are macrophages, monocytes, dendritic cells (DCs), granulocytes and B cells. IL-12 secretion is initiated once these cells encounter pathogenic organisms. (15) IL-12 represents an important connection between the innate and adaptive immune system, as they promote the orchestration of T cell differentiation. The main cellular targets of IL-12 are T cells and NK cells. Here, its hallmark is the induction of IFN-γ production, therefore fostering both innate and adaptive cell-mediated immune

Osteonecrosis may result in severe pain in joint, limitations on physical activity, some cases need to surgical intervention to restore function.

Infection is the most dreaded complication in orthopedic surgery. It causes increased morbidity and mortality and is a source of great harassment not only for the patient but the doctor as well. Incidence of Surgical site infection in USA is more than 2% [1]. Whereas in India the infection ranges from 2.5 – 41% [2]. This causes an increase in the mortality rate by 2-3 times. The rate of postoperative infection in procedures like total hip replacement (THR) and total knee replacement (TKR) is 1 – 5%. [3]

This case study shows an abscess on Brent and pain in Kristen’s knee, a week after surgery. These two patients have a few similarities in common, such as, discomfort and an unusual look to the infected area. The pain was also not felt initially, but after a few days it appeared. The difference between these patients is that Brent did not undergo a routine procedure and instead had an abscess appear out of nowhere. Kristen on the other hand, had surgery meaning there may have been some bacterial transmission during the procedure a week earlier. She had greater symptoms that included a high fever unlike Brent.

Infectious complications are commonly encountered following ORIF (Open reduction and internal fixation) ever since it has been adopted as a treatment modality for maxillofacial fractures. Early detection of infection can be difficult in the postoperative phase as many signs and symptoms may actually mimic a SIRS (Systemic inflammatory response syndrome).
