PURPOSE: Antibiotic-loaded acrylic cement (ALAC) spacers are useful for treatment of infected prostheses in the course of a two-stage revision. Spacers are handmade or are made using a commercial template, with reportedly good treatment outcomes. This study aimed to confirm the usefulness of custom-made ALAC spacers shaped like bipolar hip prostheses using a dental silicone template for treatment of infected hip prostheses, and described their manufacture. METHODS: This study evaluated 10 patients who underwent two-stage revision for treatment of infected hip prostheses...

Neck of femur fractures are the most prevalent type of injury in elderly trauma patients. Both intra and extra capsular type of fractures are equally distributed in the given population. Traditionally, Extra capsular fractures are fixed with Dynamic Hip screw or Intra medullary nailing based on the type of fracture. NICE (National Institute of Clinical Excellence) recommends fixing 31-A1 and 31-A2 fractures with DHS (Dynamic Hip Screw) whereas AO recommends fixing 31-A1 with DHS and 31-A2.1 subtype with DHS and 31-A2...

Dislocation after total hip arthroplasty (THA) remains a devastating complication and a primary cause for revision arthroplasty. Historical data indicate that a posterior approach is associated with a higher dislocation rate. In this study, we present a highly reliable and anatomical reconstruction, based on the biomechanical findings of a previous cadaveric experiment. The posterior soft tissues were repaired in 2 layers. First a reattachment of the posterior orbicular ligament is performed at the anterior capsule...

Background: The modularity in total hip arthroplasty (THA) allows orthopaedic surgeons for an exact reconstruction of hip biomechanical parameters especially in revision and tumor arthroplasty. Modular structured femoral stems using taper junctions showed increased implant breakage in the recent past. Presentation of the hypothesis: We hypothesize that a novel modular stem-neck-interface leads to less implant breakage compared to conventional femoral stems. Testing of the hypothesis: For this purpose, a novel modular femoral stem for THA was to design and manufacture...

Edge-loading of a ceramic-on-ceramic total hip replacement can lead to reproducible squeaking and revision. A patient's functional acetabular cup orientation, driven by their pelvic tilt, has been shown to be a significant factor in squeaking during hip flexion. The aim of this study was to investigate the effect of seated pelvic tilt on the contact mechanics at the ceramic bearing surface. A finite element model of a ceramic-on-ceramic total hip replacement was created. The cup was orientated at 40° inclination and 15° anteversion relative to the anterior pelvic plane...

INTRODUCTION: Ankylosing spondylitis (AS) is characterized by spinal inflammation and structural damage, primarily to the axial skeleton and sacroiliac joints. Between 25% and 70% of patients may experience progressive peripheral joint involvement, which, despite advancement in pharmacologic therapy, may necessitate surgical intervention. Total hip arthroplasty (THA) yields improved pain and functional outcomes for AS patients with hip involvement. It is unclear whether the annual rates of patients undergoing THA have changed due to newer pharmacologic management...

BACKGROUND: The direct anterior approach (DAA) offers the potential for less soft tissue insult, improved early recovery, and reduced dislocation rates. However, complications are associated with the DAA, particularly during the learning curve. We compare the DAA learning curve experience with the posterior approach regarding in-hospital complications and revision rate. METHODS: We evaluated systemic and local in-hospital complications associated with primary unilateral cementless THAs from January 1, 2010 to December 31, 2012 in 4249 patients through a posterior approach and 289 patients through a DAA...
