Traditional fluoroscopic techniques during percutaneous fixation of the posterior pelvic ring at times cannot adequately visualize errant or malpositioned iliosacral screws. Intra-operative fluoroscopic techniques have been advanced using multi-dimensional fluoroscopy to generate computed tomography-like images. This provides the surgeon not only the ability to assess iliosacral screw placement, but also the opportunity to assess reduction. We present a case series of four patients in which the Ziehm RFD multi-dimensional fluoroscopy was used to assess reduction and guidepin placement prior to definitive iliosacral screw fixation. ⋯ This retrospective case series demonstrates the direct impact that the Ziehm RFD 3D technology provides in surgical management of patients with complex posterior pelvic ring injuries.

Randomized Controlled Trial
The efficacy and safety of multiple-dose intravenous tranexamic acid on blood loss following total knee arthroplasty: a randomized controlled trial.

Multicenter Study
Blunt injuries related to equestrian sports: results from an international prospective trauma database analysis.
The objective of this study was to investigate the nature, management, and outcome of major injuries related to equestrian sports and to define the at-risk groups for serious and life-threatening injuries. ⋯ Young female riders are at risk from falling, horse-kicks, and crush-injuries. Older males in carriage-related accidents sustained the highest injury severity and mortality rate, and must specifically be targeted by future prevention initiatives. Level of evidence Descriptive Epidemiologic Study, Level II.

Recently the use of reverse shoulder arthroplasty (RSA) has increased because of a clinical perception of durable functional outcome. However, some patients unexpectedly have a poor recovery of range of motion (ROM) after surgery. Objective factors such as initial diagnosis, pre- and intra-operative ROM, deltoid impairment or arm lengthening have previously been associated with anterior forward flexion (AFF). This study sought to determine if subjective pre-operative factors influence the rate and timing of ROM recovery after RSA. ⋯ Level II, Prospective Cohort Study, Treatment Study.
