Advances in medicine and orthopaedic implant technology have dramatically increased the number of patients sustaining interprosthetic, inter-, or peri-implant fractures. For these complex clinical scenarios, there are currently no available treatment algorithms. In this review, we outline the principles, strategies, and techniques to obtain both successful reconstruction and maximum function. LEVEL OF EVIDENCE: Therapeutic Level V. See Instructions for Authors for a complete description of levels of evidence...

PURPOSE: To determine the proximity and potential risks to distal leg anatomy from anterior to posteriorly (A-P) applied distal tibia locking screws for tibial nailing. DESIGN: Retrospective. SETTING: ACS level I trauma center. PATIENTS/PARTICIPANTS: Twenty consecutive adult patients undergoing computed tomograms with intravenous contrast (CTAs) on uninjured legs. MAIN OUTCOME MEASUREMENTS: Simulated 5 mm distal interlocking screws placed in the A-P axis of an ideally placed tibial nail at 10 mm increments from the tibial plafond (10 to 40mm) were studied in relation to the distal leg's anterior anatomy...

OBJECTIVE: To evaluate the incidence of knee sepsis after suprapatellar (SP) nailing of open tibia fractures. DESIGN: Retrospective; Setting: ACS level 1 trauma center. PATIENTS/PARTICIPANTS: We reviewed 139 open tibia fractures that underwent SP nailing as definitive treatment over a 5-year period (January 1, 2011 to January 1, 2016). Most patients (90%, n = 126) underwent intramedullary nailing at the time of their initial surgery. We defined knee sepsis as intra-articular infection requiring operative debridement, either open or arthroscopically, within 1 month's time...

Stress modulation is the concept of manipulating bridge plate variables to provide a flexible fixation construct that allows callus formation through uneventful secondary bone healing. Obtaining absolute stability through the anatomic reduction of all fracture fragments comes at the expense of fracture biology, whereas intramedullary nailing, which is more advantageous for diaphyseal fractures of the lower extremity, is technically demanding and often may not be possible when stabilizing many metaphyseal fractures...

We investigated geographic variations in Medicare spending for DRG 536 (hip and pelvis fracture). We identified 22,728 patients. The median number of charges, discharges, and payments were recorded. Hospitals were aggregated into core based statistical (CBS) areas and the coefficient of variation (CV) was calculated for each area. On average, hospitals charged 3.75 times more than they were reimbursed. Medicare charges and reimbursements demonstrated variability within each area. Geographic variation in Medicare spending for hip fractures is currently unexplained...

PURPOSE: Postoperative cardiac events in orthopaedic trauma patients constitute severe morbidity and mortality. It is therefore increasingly important to determine patient risk factors that are predictive of postoperative myocardial infarctions and cardiac arrests. This study sought to assess if there is an association between anatomic area and cardiac complications in the orthopaedic trauma patient. PATIENTS AND METHODS: From 2006-2013, a total of 361,402 orthopaedic patients were identified in the NSQIP database using Current Procedural Terminology (CPT) codes...

BACKGROUND: Screws placed from posterior to anterior have been shown to be biomechanically and anatomically superior in the fixation of talar neck and neck-body fractures, yet most surgeons continue to place screws from an anterior start point. The safety and efficacy of percutaneously applied posterior screws has not been clinically defined, and functional outcomes after their use is lacking. METHODS: After institutional review board approval, we performed a retrospective review of 24 consecutive talar neck fractures treated by a single surgeon that utilized posterior-to-anterior screw fixation...

Osteoporotic fractures are difficult to manage. They pose a number of difficulties to the surgeon arising from the underlying poor bone stock compromising the intention to achieve optimum fixation. Moreover, the frail elderly patients present with a variety of medical co-morbidities increasing the risk of developing perioperative complications. Despite these recognized challenges, there are currently a number of improving technologies and strategies at the surgeon's disposal to provide more confidence with fracture fixation and maximize the chance of success...

OBJECTIVES: A few small case series have found that proximal femur fractures treated with a proximal femur locking plate (PFLP) have experienced more failures than expected. The purpose of this study was to review the clinical results of patients with acute, unstable proximal femur fractures treated with proximal femoral locking plates in a large, multicenter patient cohort. DESIGN: This is a retrospective clinical study. SETTING: The study included patients from 12 regional trauma centers and tertiary referral hospitals...

OBJECTIVES: The purpose of this study was to compare clinical and functional outcomes of patients with distal tibia fractures treated with minimally invasive plating (MIPO) or intramedullary nailing (IMN). DESIGN: Cohort study. SETTING: Level II regional trauma center. PATIENTS: Overall, 86 patients with metaphyseal distal fractures (within 5 cm of joint) with simple or no articular involvement treated by a single, fellowship trained, orthopedic trauma surgeon from 2002 to 2013...

Teriparatide [PTH (1-34)] is a genetically engineered analog of human parathyroid hormone that acts as an anabolic drug by increasing activity in both osteoblasts and osteoclasts. Intermittent (once-daily) doses of teriparatide seem to stimulate osteoblast activity and therefore result in a net increase of bone formation. It is recommended for use in post-menopausal women (PMW), men with hypogonadal osteoporosis, as well as men and women with glucocorticoid-induced osteoporosis. In vivo studies have generated important findings regarding teriparatide's role in the enhancement of fracture healing...

Osteoporotic sacral fractures, including acute and chronic insufficiency fractures, are increasing in frequency and present a number of management problem. Many of these patients are treated nonoperatively with relative immobility (eg, bedrest, wheelchair, or weight-bearing restrictions) and analgesics, which likely make the osteoporotic component worse. Surgery in this patient population may be desirable in some cases with the goals of improving mobility, relieving pain, and healing in an aligned position while minimizing deformity progression...

DESIGN: Retrospective multicenter review. SETTING: Seventeen academic medical centers. PATIENTS: Bisphosphonate-related fractures as defined by American Society of Bone and Mineral Research. Fractures had to be followed for at least 6 months or to union or revision...

OBJECTIVE: To characterize the timing, indications, and "success rates of secondary interventions, dynamization and exchange nailing, in a large series of tibial nonunions" (dynamization and exchange nailing are types of secondary interventions). SETTING: Retrospective multicenter analysis from level 1 trauma hospitals. PATIENTS: A total of 194 tibia fractures that underwent dynamization or exchange nailing for delayed/nonunion. INTERVENTION: Records and radiographs to characterize demographic data, fracture type, and cortical contact after tibial nailing were gathered...

Bleeding from the superior gluteal (SG) blood vessels at the greater sciatic notch is frequently encountered during acetabular fracture surgery. The purpose of this study is to define the positional anatomy of the superior gluteal vessels and nerve (SGVAN) at the greater sciatic notch. Twenty-three hemipelvi were dissected in whole human cadavers. The greater sciatic notch and SGVAN were visualized via a posterior surgical approach, identified deep in the greater sciatic notch, and traced superficially. Branches of the SGVAN and their anatomical relationship to each other were recorded...
