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.

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.

Trans-sacral bar osteosynthesis provides low mortality and high mobility in patients with fragility fractures of the pelvis.

Operative treatment of osteoporosis-associated fragility fractures of the pelvis (FFP) and the sacrum is advocated with immobilizing or longstanding pain, fracture progression and displacement. We analyzed clinical outcomes regarding mobility, quality of life, and mortality of patients with FFP treated with trans-sacral bar (TB) osteosynthesis through S1. Demographics, clinical data, and operation-related data of patients with an FFP treated with TB were acquired from chart review.

Quadrilateral Surface Restoration by Medial Buttressing Before Revision in Periprosthetic Acetabular Fracture: A Case Report.

Case: We report a case of periprosthetic acetabular fracture with pelvic discontinuity (PAFPD) classified Paprosky IIIb around an infected hip resurfacing prosthesis. A 3-stage revision was performed with (1) implants removal and surgical debridement to treat the infection; (2) open reduction and internal fixation using a medial buttress plate to treat pelvic discontinuity; and (3) custom-made total hip replacement with acetabular-ring reinforcement. The patient recovered with excellent clinical and radiographic results at 4-year follow-up.

Altered Regulation of the Diguanylate Cyclase YaiC Reduces Production of Type 1 Fimbriae in a Pst Mutant of Uropathogenic Escherichia coli CFT073.

The gene cluster encodes the phosphate-specific transport (Pst) system. Inactivation of the Pst system constitutively activates the two-component regulatory system PhoBR and attenuates the virulence of pathogenic bacteria. In uropathogenic strain CFT073, attenuation by inactivation of is predominantly attributed to the decreased expression of type 1 fimbriae.
