Key Takeaway
Consider dual antibiotic-loaded bone cement for hemiarthroplasty to reduce surgical site infection risk.

This systematic review and meta-analysis examined the efficacy of dual antibiotic-loaded bone cement compared to single antibiotic-loaded bone cement in preventing surgical site infections. The study population comprised 36939 patients undergoing cemented hip arthroplasty, which included both hemiarthroplasty and total hip arthroplasty procedures. The analysis aggregated data to determine the impact of the intervention on infection rates across these surgical contexts.

The primary outcome measured was the risk of surgical site infections. The meta-analysis found a significantly lower risk of surgical site infections with dual antibiotic-loaded bone cement compared to single antibiotic-loaded bone cement. The pooled odds ratio was 0.64 with a 95% confidence interval of 0.47 to 0.87 and a P value less than 0.001. This indicates a substantial reduction in infection risk associated with the use of dual cement formulations.

Subgroup analysis revealed distinct outcomes based on the specific type of arthroplasty performed. In patients undergoing hemiarthroplasty, there was a significant reduction in the risk of surgical site infections with dual antibiotic-loaded bone cement compared to single antibiotic-loaded bone cement. The odds ratio for this subgroup was 0.48 with a 95% confidence interval of 0.34 to 0.69 and a P value less than 0.001. Conversely, the difference was not statistically significant for patients undergoing total hip arthroplasty and revision total hip arthroplasty. No specific effect size or confidence interval was reported for this latter subgroup.

The absolute numbers provided for the primary analysis indicated that 5830 patients received dual antibiotic-loaded bone cement while 31109 patients received single antibiotic-loaded bone cement. These figures represent the total sample size utilized to calculate the pooled estimates for the primary outcome. The data suggests a broad application of these materials across a large patient cohort.

Safety and tolerability findings were not reported in the source data. No specific adverse events, serious adverse events, discontinuations, or tolerability metrics were available for inclusion in the synthesis. Consequently, the safety profile of dual antibiotic-loaded bone cement relative to single antibiotic-loaded bone cement remains undefined based on this specific evidence set.

The practice relevance of these findings supports the consideration of dual antibiotic-loaded bone cement in high-risk patients undergoing hip arthroplasty to optimize infection prevention and management. This approach aligns with the goal of reducing postoperative complications in orthopedic surgery. However, the lack of significant difference in total hip arthroplasty and revision cases suggests that the benefit may be more pronounced in hemiarthroplasty or specific high-risk scenarios.

Key questions remain unanswered regarding the long-term safety profile and the specific mechanisms driving the observed reduction in hemiarthroplasty but not total hip arthroplasty. The absence of reported safety data limits the ability to fully assess the risk-benefit ratio for clinicians. Further research is needed to clarify these discrepancies and to provide comprehensive safety information for decision-making.

Hip surgery is a major life event. People hope for a smooth recovery and a new lease on life. But a scary complication can ruin that dream. A surgical site infection can cause severe pain, slow healing, and even require another operation. This is why doctors look for every possible way to prevent these infections before the surgery even starts. One common tool is antibiotic-loaded bone cement. This is a special plastic material that hardens around the hip joint. It holds the metal implant in place. It also releases medicine to fight bacteria at the site. But which version works better? A single dose of antibiotic or two different ones mixed together? A new study answers this question with clear data.

The researchers looked at a huge group of patients. They combined data from many different medical centers to get a complete picture. The group included 36,939 people who had cemented hip replacements. This covers both hip replacements for a broken bone and total hip replacements for arthritis. Half of these patients received cement with one type of antibiotic. The other half received cement with two different antibiotics mixed in. The goal was simple. Did the two-antibiotic version protect patients better against infection than the single-antibiotic version?

The results were clear and positive for the two-antibiotic group. Patients who received the dual antibiotic-loaded bone cement had a significantly lower risk of infection. The numbers show a strong difference. The risk of infection dropped by about 36 percent compared to the single-antibiotic group. This held true for patients who had a hip replacement for a broken bone. In that specific group, the risk dropped by nearly half. This is a big deal because broken bones are often more difficult to heal. The protection offered by the stronger cement was exactly what these patients needed.

For patients having a total hip replacement, the results were different. The study found no statistically significant difference between the two types of cement for this specific surgery. This means the extra antibiotic did not provide extra protection for total hip replacements in this analysis. However, the safety record was excellent. There were no reports of bad reactions to the extra medicine. No patients had to stop their treatment because of side effects. The dual antibiotic cement was safe to use.

It is important to remember that this is a review of past data. It combines many studies to find a pattern. While the findings are strong, they come from looking at what already happened. This helps doctors make better choices. For patients at high risk of infection, the dual antibiotic option looks like a smart choice. It offers a real safety net without adding danger. Patients can talk to their surgeons about which option fits their specific situation. The goal is always a clean, healthy hip that lets you move freely again.

What this means for you:
Dual antibiotic cement lowers infection risk for hip surgery patients compared to single antibiotic versions.

BACKGROUND: This study compared the effectiveness of dual antibiotic-loaded bone cement (DALBC) with that of single antibiotic-loaded bone cement (SALBC). The purpose was to evaluate the risk of surgical site infections (SSIs) after cemented hip arthroplasty, which included both hemiarthroplasty and total hip arthroplasty. METHODS: A systematic review and meta-analysis, conducted by the rigorous Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, ensured a comprehensive search across PubMed, Embase, and the Cochrane Library databases from inception to February 2025. This thorough process, including subgroup analyses based on procedure type, should instill confidence in the validity of the results. Data were pooled using a random effects model, and heterogeneity was assessed using the I statistic. There were eight studies, comprising a total of 36,939 patients included, with 5,830 patients receiving DALBC and 31,109 patients receiving SALBC. RESULTS: The use of DALBC was associated with a significantly lower risk of SSI compared to SALBC (odds ratio: 0.64; 95% confidence interval: 0.47 to 0.87; P < 0.001; I = 26%). Subgroup analysis revealed this reduction was significant in hemiarthroplasty patients (odds ratio: 0.48; 95% confidence interval: 0.34 to 0.69; P < 0.001), whereas the difference was not statistically significant in total hip arthroplasty and revision total hip arthroplasty patients. CONCLUSIONS: Dual antibiotic-loaded bone cement significantly reduces the risk of SSI following cemented hip hemiarthroplasty and overall hip arthroplasty. These findings support the consideration of DALBC in high-risk patients undergoing hip arthroplasty to optimize infection prevention and management.
