Case Study and Pathogenic Causes
Case Study “A man in his late thirties was referred to a specialist bone infection service. He had congenital hip dysplasia which had undergone bilateral hip replacements by the age of 21 years. In his early thirties, the left prosthetic hip was replaced because of mechanical problems, with the right side replaced the following year. A year later he developed bilateral discharging sinuses over the hips and underwent several incision and drainage procedures.”
Potential Pathogen In the case of the individual that developed an infection after receiving bilateral prosthetic hip replacement, the pathogen that appears to be the most likely culprit is Staphylococcus aureus (S. aureus). The patient likely did not …show more content…
Once this occurs, the pathogen can colonize on the prosthetic surface which often reduces the efficiency of the body’s immune response as well as treatment through the use of antibiotics (Moran, Byren & Atkins, 2010; Peace, 2012). Often times, in late onset infections, presentation occurs in the form of joint pain that seems to get worse, restricted movement, early loosening of the prosthetic joint, inflammation and sinuses (Moran, Byren & Atkins, 2010). The patient likely did not obtain the infection from the original joint replacement, but from subsequent surgeries. Outside of any existing comorbidities, having previous joint replacements or revisions can place an individual at higher risk of infection (Zimmerli, 2006). Regardless of the timeframe when infection occurs, the Staphylococci bacteria are among the most common cause of infection in surgical and prosthetic joint procedures. S. aureus, in particular, is frequently the primary contributing bacteria of late onset infections (Moran, Byren & Atkins, 2010). During a case study of post-surgical infections, over half of the S. aureus infections were also found to be caused by the methicillin-resistant S. aureus strain, also known as MRSA (Anderson, et. al., 2010).
