The optimal surgical treatment of displaced proximal humerus fractures (PHFs) remains controversial. There are advocates for both open reduction and internal fixation with plate and screws (ORIF) and intramedullary nailing (IMN). The purpose this study was to evaluate the early-term clinical and radiographic outcomes of IMN for isolated, displaced 2-part surgical neck PHFs using a modern, straight nail system and to determine the effect of preoperative patient and fracture characteristics on outcome. ⋯ Straight IMN is a reliable treatment for displaced 2-part surgical neck PHFs with excellent radiographic and clinical outcomes in early follow-up. The implant facilitated anatomic or acceptable alignment of the fracture in the vast majority of patients.

This study intended to determine the properties of induced membranes after various periods of polymethyl methacrylate (PMMA) retention and the effect of different retention intervals on subsequent defect repair. ⋯ The induced membrane displays angiogenesis, osteogenesis, and MSC-related properties from the 2- to 20-week intervals. These were increased to a peak level at 4-8 weeks postoperatively and then gradually decreased. The optimal timing for bone grafting at the second stage in the presented model was 4 weeks after PMMA insertion.

Observational Study
Comparison of internal and external fixation after debridement in the Masquelet technique for Cierny-Mader type IV tibial post-traumatic osteomyelitis.
To compare the effect of internal fixation vs. external fixation after debridement in stage I of the Masquelet technique for Cierny-Mader (C-M) type Ⅳ chronic post-traumatic tibial osteomyelitis. ⋯ There were no differences between the two fixation methods after debridement in stage I of the Masquelet technique for C-M type Ⅳ chronic post-traumatic tibia osteomyelitis.

Pelvic fracture is a severe injury resulting in high mortality and disability rate, and brought heavy health burden. However, existing research conclusions only restricted to the national level while global estimation of pelvic fracture was lack. We aimed to estimate the global incidence, prevalence, and years lived with disability (YLDs) of pelvic fracture by region, age, gender, cause and sociodemographic index (SDI). ⋯ The global health burden of pelvic fracture still remained high during the past thirty years. More policies and strategies are needed to face the challenge brought by population growth and aging.

The purpose of this study is to document the annual incidence and incidence trends of pediatric traumatic brain injury (pTBI) in Finland over the course of 21 years. ⋯ The overall incidence of diagnosed pTBI has increased in Finland especially since 2010. Boys have higher incidence of diagnosed pTBI in all age groups. Most of the increase was due to increase in the concussion diagnoses, which may be due to the centralization of EDs into bigger units and increased diagnostic awareness of mild pTBI.
