With the advent of mixed martial arts (MMA) growing in popularity, there has been a described increase in its participation. The term MMA generally describes the hybridization of combat disciplines including but not limited to: karate, judo, jiu-jitsu, wrestling, taekwondo, boxing, kickboxing, and Muay Thai. With increased participation in MMA and martial arts, differing physical demands are placed on participants. Due to the physical nature of combat sports, there are injuries associated with participation. The purpose of this study is to report the incidence and characteristics of injuries seen from various martial art disciplines presenting to United States Emergency Rooms in order to educate participants and providers alike about risks assumed with participating in martial arts. ⋯ Martial arts injuries are a significant source of musculoskeletal injuries among patients presenting to US emergency rooms. Lower extremity injuries are seen most frequently, with patients rarely requiring hospital admission. Using this information, both providers and participants may be better equipped to make educated decisions on injury prevention and treatment.

Predictors of mortality in periprosthetic fractures of the hip: Results from the national PPF study.
Periprosthetic fractures (PPFs) around the hip joint are increasing in prevalence. In this collaborative study, we aimed to investigate the impact of patient demographics, fracture characteristics, and modes of management on in-hospital mortality of PPFs involving the hip. ⋯ The in-hospital mortality rate of PPFs around the hip exceeds 5%. The fracture subtype and mode of management are not independent predictors of mortality, while patient factors such as age, AMTS, history of PVD, pneumonia, and renal failure can independently predict mortality. Peri-operative optimisation of modifiable risk factors such as lung and kidney function in patients with PPFs around the hip during their hospital stay is of utmost importance.

Exchange nailing (EN) or augmentation plating (AP) has been employed to treat nonunions after intramedullary nailing for femoral shaft fractures. Although instability is a factor in hypertrophic nonunion, mechanical evaluations have been limited because the contribution of the callus to fracture site stability varies with healing. Our previous study illustrated the potential for evaluation using a finite element analysis (FEA) that incorporates callus material properties. This study aimed to mechanically evaluate revision surgery for nonunions using FEA. ⋯ For EN, the increase in diameter, not length, is important to suppress instability. AP reduces instability, comparable to a 2 mm increase in nail diameter, and screw fixation closer to the fracture site reduces instability. This study suggest that AP is mechanically equivalent to EN and could be an option for revision surgery for femoral shaft nonunions.

Recidivism is common following injury. Interventions to enhance patient engagement may reduce trauma recidivism. Education, counseling, peer mentorship, and other resources are known as Trauma Recovery Services (TRS). The authors hypothesized that TRS use would reduce trauma recidivism. ⋯ Level II; Prognostic.

Purpose of this study was to identify factors affecting return to work time and functional outcomes after low-velocity gunshot injuries related to foot. Related complications are also analyzed. ⋯ Level IV, Case series.
