OBJECTIVES: Regarding intracapsular femoral neck fractures, the main focus of research is the correlation between fracture-related complications and prognostic factors. The purpose of this study was to evaluate the correlation between complications required surgery (fracture-related treatment) and, among others, several less extensively investigated prognostic factors (day of surgery, co-morbidities, hospital type) in a 2-year period following internal fixation in young adults with intracapsular femoral neck fracture. METHODS: Retrospective analysis of femoral neck fractures occurred in Hungary in 2000, based on data obtained from the National Health Fund Administration. The data were validated and completed by a questionnaire carried out in all 60 institutions enrolled. Patients with polytrauma were not included into the study. The effects of prognostic factors were analysed by uni- and multivariate logistic regression (p„T0.05) in three groups: 1) all fracture-related treatments; 2) non-prosthetic; and 3) prosthetic treatments. RESULTS: Out of 413 patients, 17.92 % required further fracture-related treatment. In 7.75% non-prosthetic, and in 10.17% prosthetic treatment was performed. We demonstrated the odds ratios by multivariate regression analysis according to risk factors [95 % confidence interval, CI] are also given. Fracture displacement ORƒ2.243, CI:[1.036-4.858] weekend surgery ORƒ2.347, CI[1.049-5.248], infections ORƒ3.681, CI:[1.172-11.55], central nervous system-related co-morbidities ORƒ3.639, CI:[1.421-9.318] and the county hospital level of management ORƒ2.356, CI:[0.997-5.568] were associated with significantly increased risk for further surgery. CONCLUSION: To reduce the influence of risk factors, standardization of the substantive traumatologic and orthopedic professional guidelines, as well as the introduction of common orthopedic-trauma patient care (British model) are suggested. To achieve high-quality standardized patient management, personal and material conditions are required to be accessible every day of the week. In the presence of co-morbidities, reduction of their harmful effects should be a major consideration by focusing on the patient both in the peri- and postoperative periods.
