Introduction: Stiffness is increased in vertebrae after kyphoplasty with bone cement is performed, which cause an increase in subsequent fractures in adjacent levels. This has led to increased interest in alternative filling materials such as bioactive calcium phosphate ceramics or silicon-based polymers. This study's objective is to compare the results between kyphoplasty with bone cement and with the VK100 silicone.
Materials and methods: This is a comparative, prospective study involving 64 patients, 23 treated using VK100 and 41 with PMMA. Clinical, radiological and functional results (Oswestry) and quality of life and (EQ-5D) were analyzed and compared between both groups, focusing on differences in subsequent fractures in adjacent levels.
Results: There are no differences between the two treatments in terms of epidemiological factors (age and sex) or hospital management. A significant difference is observed in the gain of vertebral body height, with greater improvement in those treated with PMMA. There is also a higher fracture rate in the PMMA group, the difference is not significant. Finally, both treatments show similar outcomes in pain relief and quality of life.
Conclusion: Both VK100 Elastoplasty and PMMA Kyphoplasty are effective treatments for vertebral fractures. VK100 has a lower rate of complications and adjacent fractures. However, long-term results in terms of pain relief and quality of life are similar, making both treatments equally valid.
Introduction: Ankle fractures are increasingly common in frail patients, with hospitalization being the principal cost driver, particularly for the elderly who often need referral to nursing facilities. This study aims to identify factors affecting resource utilization per admission (hospital and nursing) in the fixation of low-energy ankle fractures.
Materials and methods: This retrospective cohort study examined patients undergoing fixation for low-energy ankle fractures. The primary outcome was the length of hospitalization. Secondary outcomes included delays in fixation and the need for referral to a nursing institution. Multiple linear and logistic regression models were used to determine predictors related to patient demographics, injury characteristics, and treatment.
Results: We analyzed 651 patients with a median age of 58years. The median hospitalization duration was 9days, primarily before surgery. Extended hospitalization was associated with antithrombotic treatment (b=4.08), fracture-dislocation (2.26), skin compromise (7.56), complications (9.90), and discharge to a nursing center (5.56). Referral to a nursing facility occurred in 17.2%, associated with older age (OR=1.10) and an ASA score ≥III (6.96).
Conclusions: Prolonged hospitalization was mainly due to surgical delays and was related to fracture-dislocations, skin compromise, and complications. Older and comorbid patients were more likely to need nursing facilities, and delays in these facilities' availability contributed to extended hospital stays.
Background: Prosthetic Joint Infections (PJI) are associated with significant morbidity and mortality, underscoring the importance of identifying the related risk factors. The objective of the present study was to evaluate whether environmental factors were correlated with an increase in PJI.
Material and method: Retrospective cohort study of 1847 consecutive hip and knee prosthesis surgeries performed at a single center over a 10-year period. All patients who underwent surgery during this period were included, with a minimum follow-up of 2 years. The association between infection cases and environmental temperature and humidity was analyzed for both the day of surgical intervention and the week following the procedure.
Results: Sixty-three cases of infection (3.4%) were identified. No statistically significant differences were observed in the infection rate according to the month (p=0.13) or season (p=0.42) in which the surgery was performed. Furthermore, no significant association was found between the incidence of PJI and the average temperature or humidity on the day or week following the prosthesis implantation.
Conclusions: Environmental temperature and humidity do not influence the incidence of PJI in regions with an oceanic climate. The increase in PJI according to environmental conditions is primarily observed in large-scale studies based on national registries.
