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.

The effectiveness of using intraoperative robotic C-arm cone-beam computerized tomography (CT) to locate rib fractures during surgery was compared to using pre-operative CT. ⋯ Intraoperative localization of rib fracture sites with cone-beam CT is an effective method for rib fracture stabilization.

There is a growing understanding of the specific characteristics of insufficiency fractures of the pelvis and of general requirements for the treatment of affected patients with focus on early mobilization and effective pain reduction as the main goals of therapy. While there is consensus on the significance of achieving stability of the dorsal pelvic ring structures there is still an open discussion about the potential benefits of additional stabilization of an anterior fracture component. Within a biomechanical test setup, two established methods of dorsal fracture fixation were tested under axial loading (25-1200 N; 1000 test cycles) on an explicit osteoporotic bone model (n = 32) with a standardized FFP type IIIc fracture with and without additional fixation of the anterior fracture component. ⋯ The fixation with the trans sacral bar and the additional anterior screw fixation showed the highest rate of stability (p = 0.0014), followed by the double SI-screw fixation with stabilization of the anterior fracture (p = 0.0002). During testing, we observed the occurrence of new sacral fractures contralateral to the initial fracture in 22/32 samples. The results let us assume that stabilization of an additional anterior fracture component relevantly improves the stability of the entire ring construct and might prevent failure of the dorsal stabilization or further fracture progression.

Population-based knowledge on the occurrence of femoral shaft fractures is necessary for allocation of health care services, optimization of preventive measures, and research purposes. This nationwide study aimed to provide an overview on the incidence of femoral shaft fractures over a 15-year period and to gain insight into health care consumption and work absence with associated costs in the Dutch population. ⋯ The incidence rate of femoral shaft fractures increased over the past 15 years in the Netherlands. Mean HLOS per patient has decreased in all age groups and in both sexes. Health care costs were highest for female octogenarians.

The localization of the perforator artery for the performance of digital artery perforator (DAP) flaps poses a challenge. This study aims to describe the anatomical pattern of the perforator arteries originating from the proper digital artery in fresh cadaveric triphalangeal digits and to use this pattern as a point of reference for performing these flaps. ⋯ We present a homogeneous perforator artery anatomic pattern, by finger, phalanx, finger side, gender and laterality, consisting of a high density of perforator arteries in the distal proximal phalanx region, throughout the middle phalanx and in the proximal distal phalanx region, which would be the areas of greatest certainty to help predict the favorable evolution of a digital artery perforator flap in the fingers.
