OBJECTIVE: To determine whether the addition of an anterior superior iliac spine (ASIS) osteotomy to the lateral window, when combined with the anterior intrapelvic (AIP) surgical approach, would improve visualization of the iliopectineal eminence and allow for predictable and safe clamp application. METHODS: Ten lateral window approaches to the iliac fossa were developed in conjunction with the AIP approach on 10 fresh-frozen cadaveric pelvi. A calibrated digital image was taken from the surgeon's optimal viewing angle to capture the visualized osseous surface of the false pelvis with emphasis on the iliopectineal eminence...

OBJECTIVES: We hypothesize that the anatomic center of the distal tibia is just lateral and anterior to the center of the distal tibia articular surface in the coronal and sagittal planes, respectively, and that placement of the nail along this axis results in improved rates of malalignment when treating distal tibia fractures. DESIGN: Retrospective study. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence...

We identified rare coding variants associated with Alzheimer's disease in a three-stage case-control study of 85,133 subjects. In stage 1, we genotyped 34,174 samples using a whole-exome microarray. In stage 2, we tested associated variants (P < 1 × 10(-4)) in 35,962 independent samples using de novo genotyping and imputed genotypes. In stage 3, we used an additional 14,997 samples to test the most significant stage 2 associations (P < 5 × 10(-8)) using imputed genotypes. We observed three new genome-wide significant nonsynonymous variants associated with Alzheimer's disease: a protective variant in PLCG2 (rs72824905: p...

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.

PURPOSE: To determine the proximity and potential risks to distal leg anatomy from anterior to posterior (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 (computed tomography angiograms) 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 (10-40 mm) 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...

REVIEW
Michael J Beltran, Cory A Collinge, Michael J Gardner
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...

Michael J Beltran, Phillip M Mitchell, Cory A Collinge
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...

#16
REVIEW
Cory Collinge, Juan Favela
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...

REVIEW
Cory A Collinge, Brett D Crist
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...

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...
