Gender-specific differences in the workplace in general and in the field of orthopedics and trauma surgery in particular are still clearly identifiable, and are becoming more and more pronounced in the social consciousness. ⋯ The proportion of female doctors in various fields of orthopedics and trauma surgery in the clinic and in science is increasing. There is still a clear discrepancy in leading positions in clinics, in the acquisition of an additional title, and on the boards of professional associations. In some fields, such as pediatric and hand/foot/ankle surgery, the proportion of women is higher than in other sub-areas of orthopedics and trauma surgery.

Randomized Controlled Trial
Vitamin E-blended versus conventional polyethylene liners in prostheses : Prospective, randomized trial with 3-year follow-up.
Despite continuous technical improvements, polyethylene wear debris induced periprosthetic osteolysis remains the main cause for failure of hip arthroplasty. Progressive oxidation of polyethylene was identified as another risk factor for material failure. To overcome this problem, antioxidants such as vitamin E (alpha-tocopherol) were supplemented by diffusion into the latest generation of polyethylene liners. ⋯ The present study demonstrates that the supplementation of vitamin E to polyethylene liners is reliable and safe without showing higher complication rates compared with conventional polyethylene liners. The shortterm clinical outcome of vitamin E-blended (UHMWPE‑XE) is equivalent to those of conventional highly cross-linked polyethylene liners.
