Proc Inst Mech Eng H 2020 Jul 9:954411920935759. Epub 2020 Jul 9.

Department of Mechanical and Industrial Engineering, Ryerson University, Toronto, ON, Canada.

This study provides the first biomechanical comparison of the fixation constructs that can be created to treat transverse acetabular fractures when using the "gold-standard" posterior versus the anterior approach with and without a total hip arthroplasty in the elderly. Synthetic hemipelvises partially simulating osteoporosis (n = 24) were osteotomized to create a transverse acetabular fracture and then repaired using plates/screws, lag screws, and total hip arthroplasty acetabular components in one of four ways: posterior approach (n = 6), posterior approach plus a total hip arthroplasty acetabular component (n = 6), anterior approach (n = 6), and anterior approach plus a total hip arthroplasty acetabular component (n = 6). All specimens were biomechanically tested. Read More

Surgical Hip Dislocation for Small Posterior Wall Fracture After Hip Subluxation.

J Orthop Trauma 2020 Aug;34 Suppl 2:S19-S20

Department of Orthopaedic Surgery, Boston Medical Center, Boston University Medical School, Boston, MA.

This case demonstrates a recognized association between an acetabular injury pattern and underlying morphology of the hip. In the patient discussed, hyperflexion of the hip results in the engagement of the present CAM lesion, and the resulting subluxation leads to a fracture of the posterior wall and instability of the hip. This combination of pathologies was addressed with a surgical dislocation approach to address both the CAM lesion and fix the posterior wall. Read More

Geriatr Orthop Surg Rehabil 2020 24;11:2151459320936444. Epub 2020 Jun 24.

Department of Orthopedic Surgery, School of Medicine, Jichi Medical University, Shimotsuke, Japan.

Introduction: The TFN-ADVANCED Proximal Femoral Nailing System (TFNA) 235 mm (DePuySynthes) and Proximal Femoral Nail Antirotation (PFNA)-II 240 mm (DePuySynthes) were developed to obtain better stability for patients with trochanteric hip fractures without increasing surgical time and amount of blood loss. However, there are currently no studies concerning clinical and radiological outcomes of patients treated using these proximal femoral nails (PFNs) that have been performed in the Japanese population. The aim of this study was to retrospectively evaluate the clinical outcomes associated with 235 to 240 mm PFNs for Japanese patients >70 years old with trochanteric hip fractures who could walk independently before the injury.

Preoperative Anemia Treatment With Intravenous Iron in Patients Undergoing Major Orthopedic Surgery: A Systematic Review.

Geriatr Orthop Surg Rehabil 2020 26;11:2151459320935094. Epub 2020 Jun 26.

Department of Anesthesiology, Perioperative Pain and Medicine, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA.

Introduction: Based upon the Third National Health and Nutrition Examination Survey data, iron deficiency anemia is the cause of at least 20% of cases of anemia in adults over the age of 65. This is especially relevant in patients undergoing major orthopedic surgery as substantial perioperative blood loss is possible, leading to a high rate of allogeneic blood transfusion in total hip replacements, total knee replacements, and hip fracture repairs.

Significance: The results of this systematic review may be of interest to clinicians and hospital administrators evaluating the clinical efficacy and cost effectiveness of intravenous (IV) iron administration prior to major orthopedic surgery. Read More

Gene Kitamura

Eur J Radiol 2020 Jun 21;130:109139. Epub 2020 Jun 21.

University of Pittsburgh. University of Pittsburgh Medical Center (UPMC)Department of Radiology, 200 Lothrop St., UPMC Montefiore, Room NE 538, Pittsburgh, PA 15213, United States. Electronic address:

Purpose: Recent papers have shown the utility of deep learning in detecting hip fractures with pelvic radiographs, but there is a paucity of research utilizing deep learning to detect pelvic and acetabular fractures. Creating deep learning models also requires appropriately labeling x-ray positions and hardware presence. Our purpose is to train and test deep learning models to detect pelvic radiograph position, hardware presence, and pelvic and acetabular fractures in addition to hip fractures. Read More

The 5 and 11 Factor Modified Frailty Indices are Equally Effective at Outcome Prediction Using TQIP.

J Surg Res 2020 Jun 30;255:456-462. Epub 2020 Jun 30.

Department of Surgery, University of Alabama at Birmingham, Birmingham, Alabama.

Background: The 5-factor modified frailty index (mFI-5) and the 11-factor modified frailty index (mFI-11) are equally effective in predicting adverse outcomes in the American College of Surgeons National Surgical Quality Improvement Program database. The similarly structured American College of Surgeons Trauma Quality Improvement Program (TQIP) database has not been studied with these two frailty indices. We hypothesized that the mFI-5 and mFI-11 could similarly predict adverse outcomes with TQIP data. Read More

The dangers of ignoring underlying trends in before-and-after studies - A cautionary tale using hip fracture mortality data.

J Orthop Surg (Hong Kong) 2020 Jan-Apr;28(2):2309499020935996

South Western Sydney Clinical School, UNSW Australia, Ingham Institute of Applied Medical Research, NSW, Australia.

Background: Before-and-after studies are a valuable study design in situations where randomization is not feasible. These studies measure an outcome both before and after an intervention and compare the outcome rates in both time periods to determine the effectiveness of the intervention. Before-and-after studies do not involve a contemporaneous control group and must, therefore, take into account any underlying secular trends to separate the effect of the intervention from any pre-existing trend.
