What is hardware disease?
Hardware Disease occurs after an animal ingests a metallic object that then perforates the wall of the reticulum. This perforation results in an infection that can be mild or severe. In the cow or sheep, the reticulum is the first chamber of the forestomachs, lying under the bottom of the esophagus.

What happens when an infection gets to the bone?
An infection in your bone can impede blood circulation within the bone, leading to bone death. Areas where bone has died need to be surgically removed for antibiotics to be effective. Septic arthritis. Sometimes, infection within bones can spread into a nearby joint.
Can hardware in ankle cause infection?
One of the most common complications with procedures involving orthopedic hardware is infection. Joint infections are foreign bodies, and all patients have an increased risk of developing surgical site infections.
What is the main cause of osteomyelitis?
What causes osteomyelitis? Osteomyelitis occurs when bacteria from nearby infected tissue or an open wound circulate in your blood and settle in bone, where they multiply. Staphylococcus aureus bacteria (staph infection) typically cause osteomyelitis. Sometimes, a fungus or other germ causes a bone infection.
What is the fastest way to get rid of cellulitis?
Treatment for cellulitis, which is an infection of the skin and tissues, includes antibiotics and addressing any underlying condition that led to the infection. Home remedies can also help cellulitis go away faster, such as keeping the area dry, using antibiotic ointments, rest, and elevating the affected leg or arm.
How do I know if my hardware is infected?
If one suspects an infection, obtain a white blood cell (WBC) count, erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP). An elevated WBC count is more beneficial with helping to detect acute infections with cellulitis and/or a wound. In late infections, the WBC count may be normal.
When should surgical hardware be removed?
Certainly, the indication for hardware removal is unquestioned in patients with surgical site infection, metal allergy, soft tissue compromise or failure of the osteosynthesis [4].
Does osteomyelitis ever go away?
Osteomyelitis is a painful bone infection. It usually goes away if treated early with antibiotics. If not, it can cause permanent damage.
Can osteomyelitis lead to death?
If left untreated or in very serious cases, osteomyelitis can lead to osteonecrosis (bone death).
Is osteomyelitis an emergency?
Osteomyelitis can present to the emergency department as an acute, subacute, or chronic orthopedic concern.
What triggers cellulitis?
What causes cellulitis. Cellulitis is usually caused by a bacterial infection. The bacteria can infect the deeper layers of your skin if it's broken, for example, because of an insect bite or cut, or if it's cracked and dry. Sometimes the break in the skin is too small to notice.
Is cellulitis caused by poor hygiene?
Is cellulitis caused by poor hygiene? Cellulitis usually appears around damaged skin, but it also occurs in areas of your skin with poor hygiene. You can maintain good skin hygiene by: Washing your hands regularly with soap and warm water.
Can cellulitis turn into sepsis?
Conditions such as cellulitis (inflammation of the skin's connective tissue) can also cause sepsis.
Why is it important not to delay treatment of infections?
It is important not to delay treatment of infections, because they can certainly worsen and spread. One of the worst ways they can spread is when they get into the bloodstream where patients develop sepsis. Sepsis happens when infection/bacteria is in the blood and can travel all around the body.
What to do if implants get infected?
If any of these implants get infected after surgery, treatment becomes more complicated. If hardware gets infected after surgery, x-rays can be helpful, but advanced imaging such as MRI or CT is often more helpful and lab work can also be helpful to determine the extent of the infection.
How long does it take to treat a bone infection?
If bone infection has developed, this is typically treated by 6 weeks of intravenous antibiotics.
Can you get infection after surgery?
Unfortunately, developing infections after surgery does still happen occasionally even with using intravenous antibiotics before surgery and proper sterile technique and preparation. There have certainly been advances in sterile technique to decrease these rates, but we still think postop infections develop in approximately 1% of surgeries.
What is hardware disease?
Hardware Disease occurs after an animal ingests a metallic object that then perforates the wall of the reticulum. This perforation results in an infection that can be mild or severe. In the cow or sheep, the reticulum is the first chamber of the forestomachs, lying under the bottom of the esophagus. The weight of metallic objects causes them ...
What is the most severe outcome of a reticulum infection?
These include local infection around the reticulum from leakage of fluid from the reticulum up to the most severe outcome, which is a puncture of the sac around the heart. Local infection around the reticulum interferes with normal gastrointestinal flow and motility, causing mild to severe disease.
What is hardware disease in cattle?
Hardware disease in cattle occurs when a sharp object penetrates the gut lining and damages some other organ or creates peritonitis (infection within the abdomen).
How to tell if cattle have hardware disease?
The most common signs of hardware disease in cattle are abdominal pain and discomfort. “The animal stands humped up with elbows out away from the body. Head and neck may be extended. The animal may be breathing hard, and grunt when it breathes. One way to check for hardware is to pinch the withers,” says Tibbitts.
What is the best prevention for hardware disease in cattle?
The best prevention for hardware disease in cattle is a magnet. Many dairymen routinely put a magnet in each animal when cows are young. The best prevention in feedlot animals is to have all processed feed pass over magnets.
Why won't my animal touch my hardware?
But an animal with hardware won’t do this because it hurts too much to move away from your touch. “If a wire is just starting to migrate and the animal has peritonitis, fever will be 104 to 105°F. With a chronic case, it will be around 103°F.
Case Summary
- A 70-year-old man underwent a T9-T10 facetectomy with instrumented back fusion. Postoperatively, he developed a bowel obstruction and was found to have a rectal squamous cell carcinoma. Emergency resection was performed followed by chemoradiation. A follow-up PET/CT was obtained 4 months’ status post-resection, which demonstrated suspicious uptake around th…
Imaging Findings
- On a 4-month follow up PET/CT (Figure 1), evaluation of the contrast-enhanced CT was limited due to artifacts from hardware. Fused PET/CT (C, D) and standard attenuation-corrected (AC) PET images (E,F) demonstrated increased FDG uptake in paraspinal muscles and central canal around the T9-T10 hardware as well as increased uptake in the left 10th costovertebral joint. Careful rev…
Diagnosis
- Hardware infection. The primary differential includes metastasis from known colorectal cancer, primary malignancy, or infection. Colorectal metastasis is least likely in the spine and synchronous primary is also least likely in surgical bed. Given the patient’s recent surgical history, the patient’s primary physician and oncologist were notified of...
Discussion
- Attenuation is a major issue in PET imaging, even more so than traditional CT or SPECT imaging, in part because PET requires simultaneous detection of two coincident 511 keV photons released by the annihilation of a positron produced by F18 beta-decay, which increases the likelihood that attenuation will affect the image.1-2 In PET/CT, x-rays from a CT scan are thus used to construc…
Conclusion
- This case demonstrates how a basic understanding of physics ultimately improves our patient care. In our case, the uptake around the spinal hardware may have been incorrectly attributed to AC artifact. However, review of NAC images also showed intense uptake in this region, indicating this was true FDG uptake; in our case due to infection. This case also highlights why review of N…
