Anterior extrapelvic approaches to the acetabulum.

Anterior approaches to the acetabulum can be distinguished into extrapelvic, intrapelvic and combined extrapelvic and intrapelvic approaches. Historically, the extrapelvic ilioinguinal approach was introduced in the French, English and German literature during the late 60s and became gradually the Gold-standard in treating anterior acetabular fractures. In the meantime, the intrapelvic approach, introduced by the Helsinki group, is favored by many surgeons with ongoing interest allowing direct antero-medial access to the true pelvis below the linea terminalis, to the quadrilateral plate and medial side of the posterior column.

Navigation and 3D-imaging in pelvic ring surgery: a systematic review of prospective comparative studies.

Background: Few literature reviews have been published focusing on navigation, robotic or pre-operative planning using 3D-imaging technology (3D-printing, 3D-planning). To our knowledge, no reviews have been performed to assess and compare all these modalities together versus control groups (conventional fluoroscopy) through high Randomized Control Trials (RCTs) and Prospective Control Studies (PCSs). The aim of this study was to assess and compare 3D-imaging technologies from pre-operative planning to per-operative navigation and robotic in the management of pelvic ring fractures through high level studies.

Functional outcomes and center of rotation restoration in total hip arthroplasty after acetabular fracture: A review of 367 hips.

Background: Total hip arthroplasty (THA) after acetabular fracture is typically performed months or years later for posttraumatic arthritis after initial conservative treatment. But THA can be performed earlier after open reduction and internal fixation (ORIF) of the fracture. The aim of this study was to determine which strategy is best.

Navigated pedicle screw insertion with the Surgivisio system: Malposition rate and risk factors - about 648 screws.

Purpose: Pedicle screw malposition rates vary greatly in scientific literature depending on the chosen criteria. Different techniques have been developed to lower the risk of screw malposition. Our primary objective is to evaluate the malposition rate associated with the use of the Surgivisio navigation system and to identify risk factors for screw malposition.

Anterior approaches in acetabular fractures: a true learning curve analysis.

Today, acetabular surgeons in training have to learn ilioinguinal and anterior intrapelvic approaches (AIP). The aim of this study was to describe the 5-years learning curve of a surgeon. Objective was to assess clinical and radiological results; and to assess factors which could influence this learning curve.

Fragility fractures of the pelvis: First 48 cases of surgical treatment at a level 1 trauma center in France.

Introduction: Longer life expectancy is accompanied by a higher incidence of fragility fractures of the pelvis (FFP), which has repercussions on mortality and nursing home admissions. Given the paucity of data at French healthcare facilities, we carried out a retrospective study to (1) evaluate how surgical treatment of FFP with posterior displacement (type III and IV according to Rommens and Hofmann) affects a patient's pain, functional status and ability to stay at home and (2) evaluate the postoperative complications and mortality rate.

Hypothesis: Surgery for posteriorly displaced FFP will relieve pain and preserve the patient's independence.

Simulation Software to Plan the Treatment of Acetabular Fractures: The Patient-Specific Biomechanical Model.

Objectives: The objective of this study was to assess the impact of using simulation software for preoperative planning: a patient-specific biomechanical model (PSBM) in acetabular surgery. The secondary objectives were to assess operating time, intraoperative bleeding, and peroperative complications.

Design: This is a prospective control study.

Succession of failures in surgical management of fragility fracture of the pelvis.

Case: We report a case of a 79-years old man who sustained a Fragility Fracture of the Pelvis (FFP) classified type IVb according to Rommens and Hofmann. After a delayed diagnosis with persistence of pain and loss of mobility, a bilateral sacroplasty was performed. Although pain relief was achieved, a fracture progression (FP) occurred with bilateral neurologic compression of L5 and S1 nerve roots with pain recurrence.

Navigated Cementoplasty With O-Arm and Surgivisio: An Ambispective Comparison With Radiation Exposure.

Background: Vertebral compression fractures (VCF) are usually treated by cementoplasty. Computerized navigation allows more accurate surgery without additional imaging acquisition for guidance and related radiation exposure. New technologies trend to optimize the irradiation for patients and surgeons.

Clinical and radiological outcomes of antegrade posterior column screw fixation of the acetabulum.

Introduction: Antegrade posterior column screw fixation (APCS) provides stable fixation while reducing the complications related to dual acetabular approaches. The objective of this study was to present the radiological and clinical outcomes of fixation of the posterior column of the acetabulum through a single anterior approach.

Hypothesis: APCS will produce better clinical and radiological outcomes relative to not placing any screws in the posterior column.

[Minimally invasive stabilization of fragility fractures of the pelvis with transsacral bar and retrograde transpubic screw].

Objective: Stabilization of fragility fractures of the pelvis (FFP) using a minimally invasive technique. Insertion of a transsacral rod into the transsacral corridor of S1. Insertion of a retrograde transpubic screw through the superior branch of the pubic bone.

Prospective assessment of key factors influencing treatment strategy and outcome of fragility fractures of the pelvis (FFP).

Background: Fragility fractures of the pelvis (FFP) are a clinical entity with an increasing significance in clinical practice. Little is known about the conditions, which influence decision making and outcome.

Setting: Level I trauma center.

Internal fixation of radiation-induced fragility fractures of the pelvis: a case series.

Background: The optimal treatment for radiation-induced fragility fractures of the pelvis (RI-FFP) is not well evaluated due to the rarity of the condition.

Purpose: The aim of this retrospective study was to assess the prevalence of RI-FFP, the radiological and clinical outcomes as well as the complications of patients treated with internal fixation.

Methods: A retrospective review of our database was performed to identify all surgically treated patients with RI-FFP.

Screw misplacement in percutaneous posterior pelvic iliosacral screwing with and without navigation: A prospective clinical study of 174 screws in 127 patients.

Background: Recent studies of iliosacral screw fixation performed using intraoperative navigation systems have shown promising results. The Surgivisio Platform is a new-generation three-dimensional intraoperative navigation tool that has been used at our institution for 2years. The aim of this prospective study was to assess the contribution of navigation in terms of iliosacral screw positioning accuracy and of radiation exposure, by comparing outcomes with vs.

Zoledronic Acid Contraindications Prevalence among Hip-Fractured Patients Aged 75 Years or Over Hospitalized in an Orthogeriatric Unit.

Objective: Zoledronic acid (ZA) is an antiosteoporotic drug that has been proven to reduce mortality after a hip fracture (HF). ZA is however underused with older HF patients. One possible cause may be the high prevalence of severe renal failure and hypocalcemia which contraindicate ZA administration.

Gait Analysis Platform for Measuring Surgery Recovery.

Gait analysis has evolved significantly during last years due to the great development of the Medical Internet of Things (MIoT) platforms that allow an easy integration of sensors (inertial, magnetic and pressure in our case) to the complex analytics required to compute, not only relevant parameters, but also meaningful indexes. In this paper, we extend a previous development based on a fully wireless pair of insoles by implementing an updated version with more reliable and user-friendly devices, smartphone app and web front-end and back-end. We also extend previous work focused on fall analysis (with the corresponding fall risk index or FRI) with the proposal of a new surgery recovery index (SRI) to account for the individual speed recovery speed that can be measured either at clinical facilities or at home in a telemedicine environment or while doing daily life activities.

Management of preoperative pain in elderly patients with moderate to severe cognitive deficits and hip fracture: a retrospective, monocentric study in an orthogeriatric unit.

Background: Patients with cognitive deficits are 3 times more likely to suffer a hip fracture than geriatric patients of the same age group without cognitive deficits. The persistence of perioperative pain following hip fracture is a risk factor for the occurrence of delirium, poor functional prognosis, and the development of secondary chronic pain. Patients with cognitive deficits receive 20 to 60% less analgesics than those without cognitive deficits.

Does intraoperative 3D navigation improve SpineJack vertebral augmentation in thoracic and lumbar compression fracture?

Introduction: The aim of this retrospective study was to evaluate the effect of navigation on the positioning of the SpineJack implant in the treatment of thoracic and lumbar compression fractures.

Methods: Between January 2018 and December 2019, all patients operated on for thoracic or lumbar fracture using the SpineJack device in stand-alone were included in this single-center study. The positioning of the SpineJack implant was analyzed on axial CT views by measuring the angle between the axis of the pedicle and the axis of the final implant.

Operative treatment of fragility fractures of the pelvis is connected with lower mortality. A single institution experience.

Background: Fragility fractures of the pelvis (FFP) represent an increasing clinical entity. Until today, there are no guidelines for treatment of FFP. In our center, recommendation for operative treatment was given to all patients, who suffered an FFP type III and IV and to patients with an FFP type IIwith unsuccessful non-operative treatment.

Virtual preoperative planning of acetabular fractures using patient-specific biomechanical simulation: A case-control study.

Introduction: The first patient-specific biomechanical model for planning the surgical reduction of acetabular fractures was developed in our institution and validated retrospectively. There are no prior studies showing its effectiveness in terms of reduction quality, operative duration and intraoperative bleeding. Therefore, we performed a case control study aiming to: 1) evaluate the effect of preoperative simulation by patient-specific biomechanical simulator on the operating time and intraoperative bleeding; 2) evaluate the effect of preoperative simulation by patient-specific biomechanical simulator on the quality of reduction.
