The aim of this study was to evaluate the efficacy of supplementary fixation in hip arthroplasty with the use of Kirschner-wires and tension band for geriatric patients suffering unstable intertrochanteric osteoporotic fractures. A total of 103 patients aged more than 75 years were recruited. A bipolar or total hip replacement was performed with additional application of Kirschner-wires and tension band, and the participants were followed up for 2 to 11 years. Physical component summary (PCS), mental component summary (MCS), visual analog scale (VAS), and Harris hip score were utilized to evaluate patients' hip pain and function, as well as the mental condition postoperatively after 1...

BACKGROUND Although periprosthetic fractures of the femur are a recognized complication of total hip arthroplasty, periprosthetic fractures of the acetabulum are rare. Simultaneous periprosthetic fractures of both the acetabulum and the femur have not been reported, to our knowledge. CASE REPORT We report a simultaneous fracture of the acetabulum and the femur in a 68-year-old female patient who had previously sustained a subcapital fracture of the femur, treated with a bipolar uncemented prosthesis. We discuss the possible mechanism of this combination of fractures...

OBJECTIVE: To study the causes and outcomes of patients with interprosthetic femoral fractures. MATERIAL AND METHODS: A retrospective review conducted on 7 patients treated between 2010 and 2013. The knee arthroplasties had been implanted for at least 5 years, and those of the hip less than a year. They were bipolar cemented in 6 patients and totally non-cemented in one patient, all of them implanted due to a displaced femoral neck fracture. They were treated using osteosynthesis with angular stability plate covering the whole interprosthetic femoral segment...

BACKGROUND: The fascia iliaca compartment block (FICB) provides an analgesic effect in patients with femur fractures. However, the postoperative pain after hip surgery is different from that after femur fracture, because of the difference in the degree and location of tissue trauma. Whether FICB provides effective postoperative analgesia in patients undergoing total hip arthroplasty is not well understood. Moreover, there is no prospective randomized study to evaluate FICB as a postoperative analgesia in hemiarthroplasty...

BACKGROUND: Allogeneic blood transfusions have inherent risk and direct cost in total hip arthroplasty. Anterior total hip arthroplasty has grown in popularity with increased utilization. This approach may offer an enhanced recovery but has been associated with increased blood loss. Several technologies have been developed including the Canady Hybrid Plasma Scalpel (CHPS) and Aquamantys Bipolar Sealer (BS) to decrease blood loss. METHODS: Two hundred forty-four consecutive patients undergoing anterior supine intermuscular total hip arthroplasty were separated by intraoperative cautery device (CHPS vs BS)...

BACKGROUND: Hip dislocation after treatment of a femoral neck fracture with a hemiarthroplasty remains an important problem in the treatment of hip fractures, but the associations between patient factors and surgical factors, and how these factors contribute to dislocation in patients who have undergone bipolar hemiarthroplasty through an anterolateral approach for femoral neck fracture currently are only poorly characterized. QUESTIONS/PURPOSES: We evaluated patients with bipolar hemiarthroplasty dislocation after surgery for femoral neck fracture treated through an anterolateral approach and asked: (1) What are the frequency, characteristics, and risk factors of bipolar hemiarthroplasty dislocations? (2) What are the frequency, characteristics, and risk factors of bipolar hemiarthroplasty dissociations? METHODS: A review of hospital records for patients who underwent bipolar hip hemiarthroplasty for femoral neck fracture at one hospital between July 2004 and August 2014 was conducted...

BACKGROUND: Total hip arthroplasty (THA) has not only been associated with best functional outcomes but also with higher dislocation risk when compared with bipolar hemiarthroplasty (HA). The functionality and activities of daily living (ADL) of patients treated with THA or HA for intracapsular hip fracture (IHF) have been scarcely investigated in comparison with the preoperative status. METHODS: Two comparable groups of 60 patients with an IHF who had undergone either THA or bipolar HA were created matching several preoperative characteristics...

INTRODUCTION: Arthroplasties of hip and knee are associated with blood loss, which may lead to adverse patient outcome. Performing arthroplasties in Jehovah's Witness patients who do not accept transfusion has been a matter of concern. We developed a protocol, which avoids transfusion in arthroplasties of Jehovah's Witness patients, and evaluated the feasibility and safety of the protocol. MATERIALS AND METHODS: The target of preoperative hemoglobin was more than 10 g/dL...

INTRODUCTION: Perioperative complications are well known during partial and total hip arthroplasty. One of the common categories of these complications is an intraoperative fractures of the proximal femur. Here we discuss a case of perforation of posteromedial cortex of the proximal femur, while doing a press fit modular bipolar hemiarthroplasty, in a young adult with secondary nonunion of the femoral neck fracture. The cause of this proximal femur perforation was residual fibular strut graft that, redirected the femoral stem into undesirable direction...

The use of bipolar components in hip surgery was introduced more than 40 years ago with the rationale of a dual-mobility hip implant. This design used a small femoral head that would decrease the rate of wear because of the smaller surface area but would still provide implant stability because of the larger outer shell that articulated with the acetabulum, decreasing dislocation rates. In April 2011, the E1 Active Articulation Hip System (Biomet, Warsaw, Indiana) was introduced to the orthopedic market. It is considered to be part of the next generation of bipolar designs, with similar designs available from competing companies, such as Stryker (Mahwah, New Jersey)...

BACKGROUND: Displaced femoral neck fractures are common in the elderly patient. The surgical treatment options consist of a hemiarthroplasty (HA) or total hip arthroplasty (THA). However, the best surgical choice is still under debate. Bipolar HAs do not address preexisting arthritic changes of the acetabulum, which may lead to an unfavorable clinical outcome. The purpose of the present study was to conduct a long term follow-up analysis of the bipolar hemiarthroplasty with particular focus on the influence of preoperative acetabular osteoarthritis on the functional outcome...

INTRODUCTION: Revision arthroplasty of the hip is becoming increasingly important in recent years. Early primary arthroplasty and longer life expectancy of the patients increases the number of revision surgery. Revision surgery of hip arthroplasty is major surgery for the patients, especially the elderly, with significant risks concerning the general condition of the patient. The aim of this work is to evaluate the outcome of bipolar hip arthroplasty as a salvage procedure for treatment of loosening of the acetabular cup with significant acetabular bone defects after total hip replacement (THR) in multi-morbid patients...
