Background and purpose - 7% of the asymptomatic population has leg-length inequality (LLI) greater than 12 mm. It has been proposed that LLI of >5 mm can be associated with an increased risk of osteoarthritis (OA) of the knee and hip. We studied a possible association between LLI and OA of the knee and hip joint. Patients and methods - We followed 193 individuals (97 women, 96 men) for 29 years...

PURPOSE To evaluate the usefulness of navigated acetabular cup fixation for total hip arthroplasty in patients with acetabular deformity or revision total hip arthroplasty. MATERIALS AND METHODS This study enrolled 28 patients with at least 12 months' follow-up. The safe zone of the acetabular cup was defined as 40°±10°in inclination and 15°±10°in anteversion. The authors used the navigation ...

BACKGROUND Postoperative pain relief can be achieved with various modalities. However, there are only few reports that have analyzed postoperative analgesic techniques in total hip arthroplasty patients. The aim of this retrospective study was to compare the postoperative outcomes of three different analgesic techniques after total hip arthroplasty. METHODS We retrospectively reviewed the inf...

In contrast to adult rheumatoid arthritis, hips are commonly affected joints in severe, destructive, juvenile rheumatoid arthritis (JRA). Hip disease develops in 30 to 50% of children with JRA. Because of the importance of the hip joint in weight bearing the advent of hip disease in a child with JRA warns of future disability [1, 2]. The challenges for the clinician are to prevent significant h...

IntroductionMost proximal femoral deformities encountered during hip arthroplasty are secondary to degenerative processes, previous osteotomy, or fracture and could be a challenged for surgeons. Femoral deformity may angular, rotational, one of bone diameter length. Fully understanding the anatomy is first element in deciding how best treat Total Hip Arthroplasty (THA). Presentation CaseFemale ...

UNLABELLED Endoprosthetic hip arthroplasty is a surgical intervention that significantly improves the quality of the patient's life, with excellent long term results, but with an increased risk of major complications. One such complication is the periprosthetic femoral fracture, which may occur in both young and old patients due to several risk factors typical to the elderly (osteoporosis, fall...

BACKGROUND Total hip arthroplasty with subtrochanteric shortening osteotomy is widely performed for high hip dislocation. However, suboptimal leg length discrepancy correction and nonunion of the osteotomy site remain concerns. Although total hip arthroplasty using trochanteric osteotomy without subtrochanteric osteotomy was introduced, cemented implants have been more commonly used than contem...

A variety of conditions may lead to arthritis of the hip during adolescence. Although uncommon, total hip arthroplasty may occasionally be necessary for treatment of end-stage disabling arthritis of the hip in the young. There is paucity of information documenting the outcome of uncemented total hip arthroplasty in adolescents. We report our experience with total hip arthroplasty in patients un...

OBJECTIVE To determine the natural history of hip joint disease in psoriatic arthritis (PsA) and identify clinical risk factors for its early identification. PATIENTS AND METHODS 504 patients with PsA according to ESSG criteria were studied. Mean follow up was 5.7 years (range <1-45). Mean age at onset of psoriasis was 32 years and of PsA, 39 years. The most common pattern of PsA at onset was...

INTRODUCTION Computer assisted surgery was pioneered in early 1990s. The first computer assisted surgery (CAS) total knee replacement with an imageless system was carried out in 1997. In the past 25 years, CAS has progressed from experimental in vitro studies to established in vivo surgical procedures. METHODS A comprehensive body of evidence establishing the advantages of computer assisted s...
