Background: The proximal femur has a complex anatomy and its fracture is associated with high frequency of morbidity and mortality. These fractures are one of the common lower extremity fractures that may occur in young or old people. The aim of this study was to investigate the relationship between age and sex of the patients with proximal femoral fractures in different anatomical locations.
Methods: In a retrospective study, 5000 registered proximal femur fracture (39.5 men, 60.5 women) were studid in a 5-year period in a teaching hospital in Tabriz-Iran. The demographic information, mechanism of trauma and type of proximal femur fracture were extracted from the medical records. The information was classified and analyzed.
Results: Average age of patients was 73.2 ±12.3 years old (32-100 yrs old). Intertrochanteric fracture was seen more in women than men (70% vs 60%). The sub-trochanteric and femoral neck fractures occurred more in men (31% vs. 27%). 91% of fractures were intertrochanteric in patients over 65 years of age, and most of subtrochantric fractures happened below 65 years of age.
Conclustions: The intertrochanteric fracture is occurred more in the elderly and in ages above 65 years. Women are at greater risk of proximal femur fractures. The trochanteric and femoral neck fractures often occur in young people.

Background: Magnetic Resonance Imaging (MRI) of the knee joint has often been regarded as the noninvasive alternative to diagnostic arthroscopy. New technology, however, masks the importance of history and physical examination. This study aims at evaluating the accuracy of physical examination and MRI scanning in diagnosis of knee injury, including meniscal tears and cruciate ligaments ruptures.Methods: In a cross-sectional, analytic-descriptive study, 120 patients (108 males, 12 females) with knee injury who were candidates for arthroscopy were recruited in a Hospital in Tabriz during a one-year period. Prior history of arthroscopy or knee surgery was considered as exclusion criteria. A complete history and physical examination was performed and diagnosis was documented before looking at the MRI results. The final arthroscopic diagnosis was then compared with clinical and MRI studies.Results: 120 knee injury cases with a mean age of 29 (16-54) years were enrolled. Accuracy, sensitivity and specificity of clinical examination was respectively 85, 94.8 and 75.8 percent for medial meniscus, 85, 70.8 and 88.5 percent for lateral meniscus, 95.8, 98.6 and 91.7 percent for anterior cruciate ligament and 100 percent for posterior cruciate injuries. Accuracy, sensitivity and specificity of MRI were respectively 77.5, 84.2 and 71.4 percent for medial meniscal. 85.8, 56.5 and 92.8 percent for lateral meniscal, 92.5, 98.6 and 83.3 percent for anterior cruciate, and 100 percent for posterior cruciate injuries. Overall, in isolated injuries, the accuracy of clinical examination was relatively better than MRI in complex injuries, while MRI had higher accuracy in complex intra-articular injuries.Conclusion: According to our results, both physical examination and MRI scanning are very sensitive and accurate in diagnosis of knee injuries, with a slight preference of physical examination. MRI should be reserved for doubtful or complex injuries.
