The objective of this study was to analyze the results of a cemented polyethylene model that captures the hip prosthetic head. In a retrospective study we reviewed 36 cemented constrained acetabular liners implanted in patients older than 75 years (mean 83, SD : 4.4), of which 30 patients were aged 80-90 years and 26 were women. The average period of follow-up of our patients was 25.4 months (1...

Computer assisted orthopedic surgery (CAOS) is a recent concept in orthopedics. Its use in orthopedic trauma is becoming more popular. Pelvic and acetabular trauma is one of the applications where CAOS can play an important role to facilitate the surgery. In this review article, we provide an overview of the structure of CAOS with special emphasis on its role in pelvic and acetabular trauma. Th...

BACKGROUND There is no single approach that provides adequate exposure for treatment of all types of acetabular fractures. We describe our experience with an easier, relatively less invasive pubic symphysis approach (PSA) for the treatment of acetabular fractures. MATERIAL AND METHODS Between March 2011 and March 2012, fifteen patients with acetabular fracture underwent surgery using the PSA te...

This paper presents a novel approach for acetabular alignment during the implant of a prosthetic hip joint in a natural pelvis. The alignment instrument uses selective anatomic bony landmarks on the pelvis, which are accessible in surgery, to guide the placement of the acetabular component in the appropriate orientation. A closed form solution, involving both a forward and reverse analysis, is ...

The intention of this study was to investigate the influence of surgery onto the appearance of the hip joint periarticular calcification in different groups of patients who suffered the acetabular fracture. A series of 103 patients with the acetabular fracture was analysed in a retrospective case-control study during a seven-year period. The patients were divided into two groups. The case group...

We present an update of the clinical and radiological results of 62 consecutive acetabular revisions using impacted morsellised cancellous bone grafts and a cemented acetabular component in 58 patients, at a mean follow-up of 22.2 years (20 to 25). The Kaplan-Meier survivorship for the acetabular component with revision for any reason as the endpoint was 75% at 20 years (95% confidence interval...

Purpose: Surgeons performing an ilioinguinal exposure for acetabular fracture surgery need to be aware of aberrant findings such as inguinal hernias and spermatic cord lesions. The purpose of this study is to report these occurrences in a clinical series of adult males undergoing acetabular fracture fixation and a series of adult male cadavers. The secondary aim is to characterize these abnorma...

BACKGROUND Coxofemoral osteoarthritis is a chronic, disabling condition affecting people and dogs, with THA providing an excellent return to function in severely affected joints. The principal role of THA is to restore an adequate range of motion to the hip joint while transferring load from the acetabulum in order to improve the survival of the implant and enhance the limb function in the shor...

OBJECTIVES Our primary aim was to compare the long-term survivorship rates and the rates of successful osseointegration between two different types of uncemented acetabular components. INTRODUCTION Two types of alloys have primarily been used for the manufacture of the uncemented acetabular components: titanium-based and cobalt-based alloys. A titanium-based alloy appears to be more effective...

INTRODUCTION Open reduction and internal fixation (ORIF) is standard care for most acetabular fractures. With increasing numbers of acetabular fractures in the elderly, the risk of revision surgery and conversion to total hip replacement (THR) is increasing. Alarmingly, about 20-25% of acetabular fractures in the elderly following ORIF needed revision and conversion to delayed THR. METHODS Re...
