Up to 25% of acetabular fractures have poor functional outcomes in short-term follow-up. The aim of our study is to analyze predictors related to poor outcome in surgically treated acetabular fractures. Damage to the femoral head cartilage and poor fracture reduction has been reported as predictors to total hip arthroplasty (THA). ⋯ Femoral head damage and dislocation, fracture reduction, and seagull sign were the strongest predictors related to THA after surgical treatment of acetabular fractures.

Background Although rare, pathological fractures may occur in primary bone sarcomas. There have been studies reporting that such patients have a poorer prognosis than those without a pathological fracture. This study investigates the impact of pathological fractures on surgery, morbidity, functional and oncological outcomes in patients with primary bone sarcomas. ⋯ The MSTS functional scores were lower in patients with a pathological fracture than in those without a pathological fracture (p=0.001). Conclusion We conclude that a pathological fracture through a primary bone sarcoma has no adverse effect on prognostic factors such as local recurrence, distant metastasis, and survival. However, pathological fractures increase the amount of intraoperative bleeding and surgical volume and result in a longer surgery, in addition to decreased functional outcomes.

Age-related changes in blood composition have been found to affect overall health. Thus, this study aimed to understand the effect of these changes on bone healing by assessing how plasma derived from young and old rats affect bone healing using a rat model. ⋯ bone defects treated with plasma-derived from young rats showed better healing compared to defects treated with plasma-derived from old rats. The application of young and old plasmas has different effects on the proteome of bone defects.

A pilot agreement study of a new classification system for Peri-implant femoral fractures.
Peri-implant fractures occur in association with an implant, used to treat a previous injury that is still attached to the bone. We recently published a proposal for a classification system for peri-implant femoral fractures [Videla-Cés, Injury,2019]. ⋯ The proposed classification for peri-implant femoral fractures may be useful and user-friendly. Future studies are needed to assess the how clinically useful this classification system may be (the third phase in the validation process).
