Summary
Identifying patient-specific risk factors is key to reducing implant failure. This study found osteoporosis, alcohol use, smoking, depression, and penicillin allergy increase implant failure risk over time.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
- Patient Safety
Background:
- Implant failure remains a significant concern in orthopedic surgery.
- Identifying modifiable and non-modifiable risk factors is crucial for improving patient outcomes.
- Understanding the temporal relationship between risk factors and implant failure is essential.
Purpose of the Study:
- To identify patient-specific risk factors associated with implant failure.
- To determine if these risk factors change over different time periods after implant placement.
Main Methods:
- Retrospective case-controlled study of 224 patients with implant removal.
- Risk factors categorized into demographic, medical history, and treatment-related variables.
- Multivariable logistic regression used to analyze failure within 1 year, 1-4 years, and after 4 years.
Main Results:
- 82 out of 224 patients experienced implant failure.
- Osteoporosis, alcohol use, smoking, depression, and penicillin allergy were associated with increased failure risk.
- These risk factors demonstrated varying associations across different time periods post-implantation.
Conclusions:
- Multiple discrete risk factors contribute to implant failure.
- The influence of specific risk factors on implant failure is time-dependent.
- Targeting identified risk factors may help mitigate implant failure rates.

13.1K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

39.2K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...
