BACKGROUND:The aim of this study was to determine the factors affecting postoperative mortality in patients older than 65 years of age undergoing surgery for hip fracture.

Osteosynthesis with an external fixator in elderly patients with a high anesthesia risk is a fast, minimally invasive procedure in the treatment of pertrochanteric fractures, resulting in fewer pre- and postoperative complications.

Changes in the tibial inclination angle and patellar height following open-wedge tibial osteotomy do not have an adverse effect on short-term patient satisfaction.

Purpose: To restore the normal axial alignment of the lower extremity is important in reconstructive knee surgery. The aim of this study was to evaluate lower-limb alignment and posterior tibial slope. Methods: Thirty-two male and 32 female outpatients aged 22 to 46 were recruited. A full weight-bearing anteroposterior radiograph of the entire lower limb was obtained for each subject. The axial alignment was measured based on the centers of the femoral head, knee, and ankle. The tibiofemoral (TF), tibial joint (TJ), and posterior tibial slope (TS) angles were determined. Results: The mean TF angle was more varus in women (177.8˚) than men (179.2˚), and the mean TJ angle was more medially inclined in women than men. Women had a greater TJ angle than men (93.3˚ vs. 91.6˚). The mean posterior TS was greater in men than women (16.0˚ vs. 12.5˚, p < 0.05), while the mean TS angle was greater in women (14.8˚) than men (12.3˚). Conclusion: Knee alignment and geometry vary among populations. In our study, the TF angle was varus among all participants. The knee joint was more medially inclined in women than men. And also the posterior TS was greater in women than men.

Traumatic anterior hip dislocation is a rare condition compared to posterior dislocation and recurrent anterior hip dislocation is encountered even less. Myasthenia gravis is a chronic autoimmune neuromuscular disease characterized by various degrees of muscle weakness. Closed reduction is the first choice of treatment for traumatic, non-recurring hip dislocation. We report a 59-year-old female with myasthenia gravis who underwent surgical intervention for recurrent anterior hip dislocation after failure of closed reduction. To our knowledge, this is the first case with recurrent anterior hip dislocation and myasthenia gravis in the literature.
