Introduction: High-energy periarticular tibia fractures are challenging injuries with a significant risk of complications. Postoperative infection rates, although improved, remain unacceptable. Intrawound topical antibiotic (TA) application has been popularized to reduce postoperative infections.

Ipsilateral femoral neck and shaft fractures are challenging injuries, and there are different fixation options but no consensus on a superior construct. Our preferred method is cannulated screw fixation of the femoral neck and antegrade reconstruction nailing of the shaft. Compressive fixation of the femoral neck fracture with cancellous lag screws followed by reconstruction nail placement provides compressive fixation and fixed angle support of the neck fracture while allowing for more optimal treatment of femoral shaft fractures at or above the isthmus.

Butterfly vertebrae are rare developmental anomalies representing failure of formation of the vertebral body. There have only been 8 previous reports of a butterfly vertebra occurring at S1. This is the first described case of a butterfly vertebra presenting with a sacral fracture and pelvic ring injury.

Introduction: The nature of trampoline injuries may have changed with the increasing popularity of recreational jump parks.

Methods: A retrospective review was performed evaluating domestic trampoline and commercial jump park injuries over a 2-year period.

Results: There were 439 trampoline injuries: 150 (34%) at jump parks versus 289 (66%) on home trampolines.

Background & Objectives: As the overall health and life expectancy increases in the United States, the incidence of fragility fractures in elderly patients also continues to increase. Given their medical comorbidities and decreased bone mineral density, acetabular fractures in the elderly population present a significant challenge to the orthopaedic trauma surgeon. The anterior column posterior hemitransverse (ACPHT) fracture pattern is a common fracture pattern in this population, and is often associated with central subluxation/dislocation of the femoral head with articular impaction.

Objectives: This study was performed to compare patient outcomes after Reamer-Irrigator-Aspirator (RIA)-harvested bone grafting with the current gold standard, either anterior or posterior iliac crest bone graft (ICBG).

Design: Prospective randomized controlled trial.

Setting: Multicenter study at 3 geographically separate Level 1 trauma centers.

Treatment of distal tibial fractures is technically challenging. The purpose of this study was to evaluate the use of distally locked retrograde Ender nail fixation of axially stable fibular fractures associated with these distal tibia fractures. During a 4-year span, we treated 23 fibular fractures, associated with either distal tibial metaphyseal or articular fractures, with a retrograde 3.

This report presents a case describing an extremely unusual fracture pattern of a talar body fracture. We were unable to find any examples of this horizontal plane fracture pattern anywhere in the literature. Treatment of this fracture consisted of anatomic reduction with rigid internal fixation using lag screws, and surgical revision and debridement for nonunion 1 year later.
