OBJECTIVES: To review the epidemiological aspects of fractures of the tibial plateau in a level one hospital. METHODS: We retrospectively analyzed 239 tibial plateau fractures treated surgically. We took into account age, gender, trauma mechanism, classification of the injuries, associated injuries and affected side. RESULTS: 168 were male, the fifth decade has been the most affected, the mechanism of trauma, car accident was the main causal fator, 128 cases were on the left side and 22,6% had associated injuries. CONCLUSIONS: Most patients were male, in the fifth decade of life, and victim of traffic accidents, and the depression and shear fractures of the tibial plateau are the most frequent. Associated lesions were infrequent in our study. Level of Evidence II, Prognostic Studies. Investigating the Effect of a Patient Characteristic on the Outcome of Disease.
Background:Open pelvic fractures are rare but usually associated with a high incidence of complications and increased mortality rates. The aim of this study was to retrospectively evaluate all consecutive open pelvic fractures in patients treated at a single Level-1 Trauma Center during a 10-year interval.Patients and Methods:In a 10-year interval, 30 patients with a diagnosis of open pelvic fracture were admitted at a Level-1 Trauma Center. A retrospective analysis was conducted on data obtained from the medical records, which included patient’s age, sex, mechanism of injury, classification of the pelvic lesion, Injury Severity Score (ISS), emergency interventions, surgical interventions, length of hospital and Intensive Care Unit stay, and complications, including perioperative complications and death. The Jones classification was used to characterize the energy of the pelvic trauma and the Faringer classification to define the location of the open wound. Among the survivors, the results were assessed in the last outpatient visit using the EuroQol EQ-5D and the Blake questionnaires. It was established the relationship between the mortality and morbidity and these classification systems by using the Mann-Whitney non-parametric test, with a level of significance of 5%.Results:Twelve (40%) patients died either from the pelvic lesion or related injuries. All of them had an ISS superior to 35. The Jones classification showed a direct relationship to the mortality rate in those patients (p = 0.012). In the 18 (60%) other patients evaluated, the mean follow-up was 16.3 months, ranging from 24 to 112 months. Eleven (61%) patients had a satisfactory outcome. The Jones classification showed a statistically significant relationship both to the objective and subjective outcomes (p < 5%). The Faringer classification showed a statistically significant relationship to the subjective, but not to the objective outcome. In addition, among the 18 patients evaluated at the last outpatient visit, the Faringer classification showed statistical significance on the need of colostomy (p = 0.001) in the acute phase of treatment.Conclusion:We suggest the routine use of the Jones classification for the emergency room assessment and management of all open fractures of the pelvic ring. We believe the Faringer classification seems to be useful for the abdominal surgeons for the indication of gut transit derivation but not for the acute management of the bony component of an open pelvic fracture.
Background: The biomechanical behavior of Pauwels type III fractures should be taken into consideration when performing internal fixation, since this repair should resist the shear force inherent in the vertical fracture line to the greatest extent possible. Recently, the use of a small fragment plate on the medial face of the femoral neck has been proposed by some authors, with satisfactory initial results. In the current study we analyze the mechanical role a medial plate used as a buttress plate for Pauwels type III femoral neck fractures, comparing the resistance of two fixation configurations using three cannulated screws. Methods: Pauwels type III fractures were simulated in synthetic bones models and two groups were created, one of those using two parallel screws at the bottom of the femoral neck and the third screw crossing the fracture horizontally (G1), and the other fixed in the same arrangement as G1, but with the addition of a medial side plate at the apex of the fracture (G2). The constructs were subjected to axial loading until catastrophic failure. Results: The addition of a medial plate buttressing the femoral neck increased significantly the resistance to maximum loading (p = 0.003). Conclusion: Use of a medial buttress plate results in a mechanically superior construction for Pauwels type III fractures fixed with multiple cannulated screws. Lebel of evidence: Level IV. Biomechanical comparative study.
