Although open reduction and internal fixation (ORIF) has been the standard of care for acetabular fractures, recent advancements in minimally invasive techniques have allowed percutaneous fixation to gain popularity. Percutaneous technique has been described in the literature as an adjuvant to ORIF. However, isolated percutaneous fixation has the advantage of limiting soft tissue disruption, le...

Acetabular wedge augmentation is a useful technique and is recommended in situations where cup revision is likely to be excessively difficult. Numerous augmentation designs that improve the stability of the hip are now available in the market. Occasionally, however, these devices are not readily available, particularly if problems such as instability and dislocation are not anticipated preopera...

Abnormalities of the femur frequently accompany acetabular dysplasia as primary or secondary deformities. Femoral surgery is often a component of surgical treatment of acetabular dysplasia either at the onset or to treat a secondary or residual deformity. Proper analysis of the abnormal geometry of the bony femur, as well as the abnormal lever arms around the hip related to the lesser and great...

Introduction: Supine patient positioning in conjunction with twoincision minimally invasive surgery (MIS-2 incision) total hip arthroplasty (THA) increases difficulty of accurate and repeatable cup orientation in accordance with pre-operative planning. Investigators have suggested advantages of utilizing computer assisted orthopaedic surgery (CAOS) to successfully eliminate extreme outlying ace...

This aim of this work was to carry out an epidemiological study on acetabular fractures in the city of Campinas and surrounds, in view of the few published papers on this subject. Medical files with a diagnosis of acetabular fracture between the years 2004 and 2008 that were made available by the Medical Archiving Service of Hospital das Clínicas, State University of Campinas (UNICAMP) were ana...

The angle of inclination of the acetabular component in total hip replacement is a recognised contributing factor in dislocation and early wear. During non-navigated surgery, insertion of the acetabular component has traditionally been performed at an angle of 45 degrees relative to the sagittal plane as judged by the surgeon's eye, the operative inclination. Typically, the method used to asses...

Intertrochanteric osteotomy may postpone the need for total hip replacement (THR). In young patients with an acquired deformity of the femoral head and secondary osteoarthritis, a valgus intertrochanteric osteotomy may allow better congruency but the acetabular cover may become insufficient because of subluxation of the femoral head. In patients with a spherical femoral head and acetabular dysp...

The rationale for this paper was to find out assessment tools and relevant factors that may reduce pain, and improve the quality of life and ability to perform activities of daily living in surgically and conservatively treated patients who sustained the acetabular fracture. One hundred and three patients with the acetabular injury were analysed during the 10-year retrospective case-control stu...

Computer assisted surgery is becoming more frequently used in medical world. OrthoPilotTM Hip Suite CT-free navigation system (BBraun Aesculap) is one such computer assisted navigation system used for total hip replacement surgery. The validity of OrthoPilot system remains to be determined independent of the manufacturer. The main aims of this study were to investigate the accuracy of OrthoPilo...

Managing severe periacetabular bone loss during revision total hip arthroplasty (THA) is a challenging task. Multiple treatment options have been described. A custom triflanged acetabular component is a recent treatment option. The authors retrospectively reviewed 19 hips in 19 patients with massive periacetabular bone loss (Paprosky types 3A/3B and AAOS types III/IV) treated with custom trifla...
