Professor Seung-Beom Han's research lab specializes in orthopedic surgery and surgical outcomes, with a strong focus on joint replacement, trauma surgery, and perioperative complications. The lab investigates factors influencing postoperative recovery, including blood loss, acute kidney injury, hypoalbuminemia, and the impact of surgical techniques such as computer navigation and high tibial osteotomy on long-term outcomes. A key research direction involves understanding the interplay between metabolic and environmental factors—like lead exposure and calcium intake—on bone health and fetal development, particularly in maternal populations. The lab employs rigorous meta-analytical methods to evaluate surgical interventions and improve patient safety and outcomes in orthopedic care.

Non-carbapenem antibiotics showed favourable therapeutic effects on childhood UTIs caused by ESBL-producing strains. Aminoglycosides can be an alternative to carbapenems in such cases.
This study demonstrated that the new anatomical locking metal block plate could provide sufficient primary stability for open wedge HTO. The addition of a metal block to this new plate can increase the stability of the osteotomy compared to the one without a metal block.
Millions of women of child-bearing age have substantial bone lead stores due to lead exposure as children. Dietary calcium ingested simultaneously with lead exposure can reduce lead absorption and accumulation. However, the effects of dietary calcium on previously accumulated maternal lead stores and transfer to the fetus have not been investigated. We studied the effects of lead exposure of female rats at an early age on fetal development during a subsequent pregnancy. We gave 5-week-old female
There were no significant differences in the revision rate to TKA between HTO and UKA. However, results from subgroup analyses suggested that opening-wedge HTO resulted in a lower revision rate to TKA than did UKA, whereas closing-wedge HTO resulted in a higher revision rate to TKA than did UKA. In addition, UKA resulted in significantly better functional outcomes and postoperative velocity, along with less postoperative pain, fewer postoperative complications, and lower postoperative ROM. Based

This study demonstrated that early postoperative hypoalbuminaemia is an independent risk factor for the development of postoperative pneumonia in patients undergoing hip fracture surgery.
There was no significant difference in clinical outcome between adults and children with VSB despite a difference in cefepime susceptibility. Hence, different antibiotic treatment strategies may not be necessary.
Acute kidney injury was found to occur frequently after surgery for femur neck fracture. Surgeons should be aware of acute kidney injury when planning the management of patients with femoral neck fracture and consider that the duration of intraoperative hypotension is a risk factor for acute kidney injury.
