developmental dysplasia of the hip (ddh) is one of the most widely discussed abnormalities in neonates. the advantages of sonographic examination are well known, but its main disadvantage is that it might lead to over diagnosis, which might cause over treatment. variations in the incidence of developmental dysplasia of the hip are well known. during six months study since september 2006 all 130...

BACKGROUND The use of larger femoral heads has been proposed to reduce the risk of dislocation after total hip arthroplasty, but there is a lack of evidence to support this proposal. The aim of this multicenter randomized controlled trial was to determine whether the incidence of dislocation one year after total hip arthroplasty is significantly lower in association with the use of a 36-mm femo...

INTRODUCTION Bipolar hip arthroplasty is a good option for treating femoral neck fractures, although some contraindications have been indicated. We report a case of intraoperative dislocation of the trial bipolar cup into the pelvis during bipolar hip arthroplasty. CASE PRESENTATION A 74-year-old woman underwent bipolar hip arthroplasty for a femoral neck fracture (AO31-B2). She was placed in...

background: trans-scaphoid perilunate fracture-dislocation and perilunate dislocations are among uncommon injuries, most commonly seen in young patients due to high energy trauma. the treatment can be achieved either surgically by open reduc tion and internal fixation or closed reduction and casting.   methods: to compare surgical versus non-operative results of treatment of trans-scaphoid peri...

We present a retrospective review of the early results and complications in a series of 35 consecutive patients with 43 total hip arthroplasties performed through an anterior muscle sparing minimally invasive approach. We found the early complication rates and radiographic outcomes comparable to those reported from arthroplasties performed via traditional approaches. Complications included disl...

UNLABELLED Dislocation remains the leading early complication of total hip arthroplasty; surgical approach and implant positioning have been recognized as factors influencing total hip arthroplasty stability. We describe a total hip arthroplasty technique done through a single, tissue sparing anterior approach that allows implantation of the femoral and acetabular components without detaching o...

287 Abstract Introduction: Peri-prosthetic fracture is the third cause in frequency in hip revision following aseptic loosening and infection. The ones that show associated with a loosened stem (B2) or a bone stock deficit (B3) should receive femoral revision. Materials and Methods: We studied retrospectively 38 patients with types B2 and B3 femur peri-prosthetic fracture treated with distal fi...

Background: Prevalence of recurrent shoulder dislocation in patients taking tramadol has not been studiedyet so, this study aims to study the recurrent shoulder dislocation following tramadol induced seizure. Methods: In this cross-sectional study, 205 patients with recurrent shoulder dislocation complaints (2 or more) referred to Shafa Orthopedic and Iranmehr hospitals Tehran, Iran, from Oc...

Developmental dysplasia of the hip (DDH) or congenital hip dysplasia (CDH) is the most prevalent developmental childhood hip disorder. It includes a wide spectrum of hip abnormalities ranging from dysplasia to subluxation and complete dislocation of the hip joint. The natural history of neglected DDH in adults is highly variable. The mean age of onset of symptoms is 34.5 years for dysplastic DD...
