RESUMEN
INTRODUCTION: Open tibial plateau fractures are complex injuries that require specialized management to prevent complications. The objective of this study was to compare the infection risk and functional outcomes between open and closed tibial plateau fractures. MATERIALS AND METHODS: In this multicenter cohort study the propensity score matching was used to pair participants according to age, sex, and Schatzker classification. 190 patients were followed for 1 year postoperatively. The Fracture-Related Infection (FRI) Consensus Group criteria was used to diagnose infection. Knee functionality was measured using the Oxford Knee Score scale (OKS). RESULTS: The proportion of open fractures was 5.1%, and the overall incidence rate of FRI was 8% with 14% of them represented by open fractures and 4% for closed fractures (p = 0.014). Open fractures were found to be a risk factor associated with FRI, with a 5.48 times higher probability of FRI than closed fractures (odds ratio 5.41, 95% confidence interval [CI] 1.55-18.85). Among the study population, 50% had satisfactory functional outcomes of the knee (median OKS 45, IQR = 3). The median OKS was 44 (IQR = 11) in open fractures and 46 (IQR = 7) in closed ones (p = 0.03). Multivariate analysis showed that the OKS was 3 points lower for open fractures (95% CI -5.530--0.478) than closed ones, and the score was 9.7 points lower for FRI. CONCLUSION: Open TPF is a risk factor that increases the probability of fracture related infections. Functional outcomes were excellent for both open and closed TPF, with a slight difference numerical that was under the minimal clinical difference (MCID). The presence of FRI significantly decreases the functional outcome.

BACKGROUND: Tibial plateau fractures are traumatic injuries with severities ranging from nondisplaced to complicated fractures. This study describes the epidemiological characteristics of patients with tibial plateau fractures treated in five trauma clinics. METHODS: This retrospective, cross-sectional study included 1165 patients with tibial plateau fractures treated between December 2015 and May 2017. Subjects were selected from the medical records of five institutions based on the inclusion and exclusion criteria. Age, sex, laterality, fracture type, trauma mechanism, vehicle type, classification, and associated injuries were assessed via univariate and bivariate analyses. RESULTS: In total, 23.3% of patients with tibial fractures treated during the study period had tibial plateau fractures. Of those affected, 73% were men and 50% were younger than 40 years. Furthermore, 95.7% of fractures were caused by traffic accidents, 82.6% of which involved motorcycles. Fractures were closed in 93.1% of cases, and 78% of subjects had associated injuries. The most common fractures, according to Schatzker classification, were type VI (23%) and V (19.1%) fractures. CONCLUSIONS: Tibial plateau fractures are frequent injuries in our setting and mostly occur in men in their 30 s and 40 s. These fractures are typically caused by motorcycle traffic accidents. LEVEL OF EVIDENCE: IV.

BACKGROUND: Posterior wall fractures are the most frequent and account for up to 25% of all acetabular fractures, open reduction and internal fixation by a Kocher Langenbeck approach is the gold standard for this injury but even with anatomic reduction poor outcomes are higher than expected, The present study proposes a technique for open reduction and internal minimizing soft tissue and periosteal injury through a modified Kocher-Langenbeck and spring plate fixation. METHODS: This case series, descriptive, longitudinal study assessed the clinical and functional outcomes of patients with isolated posterior wall fractures of the acetabulum, the study included 24 consecutive patients from January to December 2018 who underwent open reduction and internal fixation with spring plates by a Rotator Sparing Kocher Langenbeck approach RESULTS: Clinical and radiographic assessment at 3 and 12 months using the Harris Hip Score (HHS), Merle d'Aubigné and Postel (MDP) score, and EQ-5D-3L score. RESULTS: Twenty-four patients were included in the study (5 females [20.8%], 19 males [79.2%]; mean age, 33.5 ± 13.1 years; range: 15-64 years). 41.7% of patients were admitted for hip dislocation, with 75% of these presenting a displacement greater than 20 mm; 21% for marginal impaction; 8.3% for acetabular dome involvement; and 25% for femoral head involvement. Based on the HHS, MDP, and EQ-5D-3L scores, the 12-month follow-up showed excellent outcomes in 95.8% of patients, and only one patient presented a poor functional outcome that was associated with posttraumatic arthrosis due to sequelae of femoral head necrosis. CONCLUSIONS: Excellent and good outcomes are considerably higher with this technique compared to previous papers in the literature. It is still early to assess femoral head necrosis and osteoarthritis, but these are promising results. LEVEL OF EVIDENCE: IV.
