acetabular fracture

BACKGROUND: Minimally invasive percutaneous screw fixation for pelvic ring and acetabular fractures has become increasingly popular due to its numerous benefits. However, the precise placement of the screw remains a critical challenge, necessitating a modification of the current techniques. This paper introduces a refined technique employing a modified guidewire to enhance the precision and efficiency of percutaneous fixation in pelvic and acetabular fractures. METHODS: This study details the surgical techniques implemented for correcting guidewire misdirection in percutaneous screw fixation and includes a retrospective analysis of patients treated with this modified approach over a three-year period...

The use of pelvic osseous fixation corridors and lag screw fixation in acetabular and pelvic surgery has gained popularity, especially with the recent development of intraoperative imaging and navigation techniques. However, advanced intraoperative imaging and navigation techniques require technical equipment and are costly. Therefore, traditional fluoroscopic techniques still maintains its importance. In this article, we describe a novel pelvic osseous fixation corridor, which traverses both columns of the acetabulum, along with the detailed methodology of its fluoroscopic imaging and the techniques for fluoroscopy-assisted screw placement...

BACKGROUND: Lower doses of irradiation (≤ 5 Mrad) during the manufacture of highly crosslinked polyethylene acetabular liners may result in less crosslinking and an increased wear rate. Radiostereometric analysis (RSA) studies have found that wear of more highly irradiated highly crosslinked polyethylene liners (7 to 10 Mrad) decreases at longer-term follow-up compared with earlier reports of the same cohorts. Although wear of 5-Mrad irradiated liners appears to increase at midterm follow-up, it is unclear whether that remains true at longer follow-up...

Background : This study aimed to report the long-term outcomes of total hip arthroplasty (THA) using a Conserve Plus (Wright Medical, Japan) metal-on-metal (MoM) acetabular prosthesis with a modular neck stem. Methods : This study enrolled 50 patients (10 men and 40 women; mean age, 65.8 (39-87) years) who underwent primary THA using a Conserve Plus MoM acetabular prosthesis with a modular neck stem. The preoperative diagnosis in most patients was osteoarthritis. Clinical function of hip joint outcomes was investigated using the Japanese Orthopedic Association (JOA) hip score preoperatively and at the final follow-up...

Background and Objectives : The objective of this retrospective study was to investigate the association between acetabulum fractures; the mechanism of injury; and variables such as BMI, duration of hospital stay, blood loss, and surgery time. By exploring these factors, we aim to enhance our understanding of them and their impact on the healing process and the subsequent management of pelvic fractures. Materials and Methods : This study included 67 of 136 consecutive patients who were admitted for pelvic ring fracture surgery between 2017 and 2022...

PURPOSE: The results after acetabular fracture are primarily related to the quality of articular reduction. Using the AO large femoral distractor, incarcerated fragments can be easily removed, and marginally impacted fragments can be elevated under direct visualization without further re-dislocating the joint. The current study aimed to evaluate our early results of using the AO large femoral distractor as an assisting tool during ORIF of acetabular fractures associated with marginal impaction or intraarticular incarcerated fragments...

INTRODUCTION: The Judet and Letournel classification is the most widely used classification system for acetabular fractures. Some complex fractures couldn't be classified according to this classification. The main purpose of this study was to evaluate the reliability of the Letournel and Judet classification system for acetabular fractures. MATERIAL AND METHODS: 10 acetabular fractures were analyzed among 17 orthopedic surgeons. The surgeons were asked to classify the fractures according to the Judet and Letournel classification...

INTRODUCTION: Modular titanium fluted tapered (TFT) stems have demonstrated excellent clinical success for femoral revision total hip arthroplasty (THA) surgery. This aim study reports the short-term outcomes of a novel modern monoblock TFT stem used for revision and complex primary THA with a minimum of 2 years of follow-up. METHODS: We identified 126 patients who received a single monoblock TFT stem; 26 patients for complex THA (failed fracture fixation) and 100 patients for revision THA...

Acetabular quadrilateral plate injury has become a hot spot and focus in the field of orthopaedic trauma and pelvic floor function in recent years. Although there are five fracture types,they are all based on fracture morphology,without considering the pulling force of ligaments,joint capsular and muscles. A perfect classification needs to describe the displacement of bone mass in three-dimensional space to better guide reduction and fixation. The seven incision and exposure methods are still the traditional open-eye surgery,and how to protect the criss-crossing vascular neural network and pelvic organs is still the focus...

This case report outlines the successful management of post-traumatic arthritis (PTA) in the left hip of a 60-year-old male with a history of a subtrochanteric femur fracture treated with Jewett Nail Plate osteosynthesis four decades ago. Despite seeking relief from various healthcare facilities and attempting alternative therapies, the patient experienced persistent pain and limited mobility. The decision was made to perform elective implant removal followed by total hip arthroplasty (THA). The surgical intervention involved a modified posterior approach, addressing specific challenges such as acetabular superior wall deficit and femoral sclerosis...

UNLABELLED: The goal was to investigate if patient characteristics can be used to predict 1-year post-fracture mortality after pelvic fracture. Multivariate logistic regression identified male gender, comorbidities and presence of in-hospital complications as predictors of 1-year mortality. PURPOSE: Osteoporotic pelvic fractures have significant mortality and morbidity in the older population. The aim of this study was to investigate the factors predicting one-year mortality of patients sustaining a low-impact pelvic fracture (pelvic ring and acetabulum)...

This case-report focuses on a 23-year-old soldier suffering from a fracture-related hip joint infection (FRI) due to extensively drug-resistant Klebsiella pneumoniae and S. epidermidis . The patient underwent multiple septic revision surgeries including the removal of remaining shrapnel accompanied by last-resort antimicrobial therapy with cefiderocol and colistin. Additionally, the surgeries included repeated tissue sampling for microbiological and histopathological analysis. An antibiotic-loaded cemented filler containing cefiderocol was used to improve local antimicrobial therapy...

INTRODUCTION: Advances in total hip arthroplasty (THA) have resulted in evolving revision indications and intraoperative techniques, which can influence the exposure of trainees to complex cases. We report three decades of revision experience from a tertiary referral center that trains fellows, comparing the reasons for revision and the complexity of revisions over time. METHODS: We retrospectively reviewed all revision THAs performed at our institution from 1990 to 2022...

PURPOSE: Acetabular fractures are highly complex injuries often resulting from high-energy trauma. The gold standard treatment for these injuries has become open reduction internal fixation (ORIF). The purpose of this study is to further this understanding and investigate how (1) patient demographics and (2) patient-specific risk factors affect 90-day readmission rates. METHODS: A retrospective, nationwide query of private insurance database from January 1st, 2010 to October 31st, 2020 was performed using ICD-9, ICD-10, and CPT codes...

METHODS: PubMed was searched using the terms 'Floating hip' or 'acetabular fracture' and 'Ipsilateral femoral fracture' or 'pelvic fracture' and 'Ipsilateral femoral fracture'. One author performed a preliminary review of the abstracts and references of the retrieved articles. RESULTS: The mean injury severe score reported was higher than 20...

BACKGROUND: Traumatic, posterior hip dislocations in the pediatric population are typically managed by closed reduction to achieve a concentric hip joint. The presence of an acetabular "fleck" sign, despite concentric reduction, has been shown to signify significant hip pathology. The purpose of this study was to evaluate the outcomes of open labral repair through a surgical hip dislocation (SHD) in a consecutive series of patients with an acetabular "fleck" sign associated with a traumatic hip dislocation/subluxation...

BACKGROUND: The aging population has contributed to a rising incidence of acetabular fractures in older patients, yet current evidence guiding surgical treatment is limited by small sample sizes. This study used a nationwide database to investigate outcomes in older patients undergoing open reduction and internal fixation (ORIF) versus acute total hip arthroplasty (THA). METHODS: The PearlDiver database was queried for patients aged 60 years and older with an acute acetabular fracture who underwent ORIF or acute THA (2010 to 2021)...

CASE: We present the case of a 25-year-old man with body mass index of 77 who underwent open reduction internal fixation (ORIF) of a displaced fracture dislocation of the acetabulum after a high-speed motor vehicle accident. Remarkably, he achieved full weight-bearing with minimal hip pain and has returned to independent mobility and meaningful work. CONCLUSION: ORIF of an acetabular fracture in a patient with class III obesity presents many challenges. Positioning, surgical approach, fracture manipulation, and postoperative morbidity and mortality can be managed through interdisciplinary collaboration and preoperative communication...

BACKGROUND: The pararectus approach is a minimally invasive surgical approach for anterior acetabulum fracture, with an advantage of the medial window of the modified Stoppa approach (MSA). However, it is unclear whether the pararectus approach is superior to MSA. We aimed this systematic review and meta-analysis to compare the outcomes and complications of pararectus and MSA. METHODS: We performed a data search by conducting an electronic search across databases of PubMed, Embase, Scopus, Cinahl, CNKI, and Cochrane Library and included seven comparative studies for analysis...
