Hip prosthesis replacement

Hendrik Kohlhof, Sebastian Köhring, Dieter Christian Wirtz, Hartmut Witte
The number of hip and knee arthroplasty replacement surgeries is increasing steadily. In combination with demographic aging and the number of periprosthetic complications, this development has lead to the phenomenon where the need for revision surgery is rising. The problem is, that, while implantation procedures of hip arthroplasties are more or less standardized, explantation is a non-standardized task for experienced specialists, due to the unpredictability of the adequate loosening method. The surgeon often only gets to decide on which tools and methods may be applied to detach the prosthesis, only after getting access to the operation site...

Rheumatoid arthritis (RA) is a most common inflammatory joint disease with direct invasion of joint synovial membrane, cartilage and bone. Currently, although the RA mitigation drugs are being improved continously, but these drugs only can delay the development of joint dysfunction. Total hip arthroplasty or total knee arthroplasty(THA or TKA) has become the only choices for patients with advanced RA, and the joint function and deformity of the patients after surgical treatment can be improved to some extent...

Background: Hospitals may be under pressure to implement cost saving strategies regarding prosthesis choice. This may involve the use of components which are not the first preference of individual surgeons, or those they have little experience with. We aim to examine the effect of standardizing the type of femoral stem used in a single trust, and determine whether this is safe practice, particularly in those who have never used this particular stem before. Methods: We report results at 2 years of 151 primary total hip arthroplasties performed using a single femoral stem...

BACKGROUND: Hip dislocation is a major complication of total femoral prosthetic reconstruction (TFR) after femoral tumor resection. Hip dislocation can occur because of inadequate functional abductor musculature, inadequate hip capsule repair, or a long lever arm after total femur replacement. To eliminate the negative effects of these factors on the risk of hip dislocation, the use of artificial ligaments may help to increase the stability of the hip joint. We aimed to determine whether application of an artificial ligament would improve limb function and active range of movement (ROM) after TFR...

This case report follows a woman who had a total hip replacement in 1992 when she was 45 years old. Six serial computed tomography (CT) examinations over a period of 13 years provided information that allowed her revision surgery to be limited to liner replacement as opposed to replacement of the entire prosthesis. Additionally, they provided data that ruled out the presence of osteolysis and indeed none was found at surgery. In 2004, when the first CT was performed, the 3D distance the femoral head had penetrated into the cup was determined to be 2...

BACKGROUND: Several surgical options for the reconstruction of massive bone defects have been described and include biologic methods with autografts and allografts, and the use of tumor endoprostheses (total femoral replacement, TFR). Several types of modular TFR are available, but nevertheless unpredictable outcomes and high complication rates have been described from most authors. The present study aims to compare results after TFR performed with modular total femur prosthesis MML (Fa...

BACKGROUND: The aim of this study was to present the long-term survivorship (20 years) of total elbow arthroplasty (TEA) for a relatively large population and to compare different prosthesis brands and patient subgroups. METHODS: Between 1994 and 2017, a total of 838 primary TEAs were reported to the Norwegian Arthroplasty Register. Implant survival was calculated using the Kaplan-Meier method. Risk differences were examined using Cox regression analyses and exact Cox regression for rare events...

An infant boy underwent hip disarticulation for infantile fibrosarcoma immediately after birth. His rehabilitation began when he was 4 months old and involved training with his left (residual) leg. He could stand with support at 12 months. His initial prosthesis fitting was performed at the age of 13 months. He could stand and walk with support at 15 months of age and could walk with no additional support and go up and down stairs at 2 years. A single-axis prosthetic knee joint was introduced at the age of 2 years 3 months...

BACKGROUND: A novel revision technique for failed hip resurfacings involves retention of the acetabular cup, if well-fixed, which is mated to dual-mobility (DM) prosthesis in a traditional hip replacement configuration. It is unknown whether existing damage on the retained cup will result in unacceptable wear of the DM prosthesis. METHODS: Thirty retrieved Birmingham (Smith & Nephew) monoblock cups were visually scored for damage features and area of coverage. Surface roughness measurements were obtained within each damage feature as well as reference points on each cup...

OBJECTIVES: In most European countries, innovative medical devices are not managed according to cost-utility methods, the reason being that national agencies do not generally evaluate these products. The objective of our study was to investigate the cost-utility profile of prostheses for hip replacement and to calculate a value-based score to be used in the process of procurement and tendering for these devices. METHODS: The first phase of our study was aimed at retrieving the studies reporting the values of QALYs, direct cost, and net monetary benefit (NMB) from patients undergoing total hip arthroplasty (THA) with different brands of hip prosthesis...

BACKGROUND: The incidence of post-surgical chronic pain ranges between 20% and 40% in Europe. Osteoarthritis pain after prosthesis implantation is one of the most severe secondary syndromes, depending not only on surgery but also on organic changes before and after joints replacement. No data are available about risk factors. An excessive inflammatory response plays a central role but a best therapy is not defined yet. It is not clear whether opioid administration could influence post-surgical pain and lead to tolerance or addiction...

CASE: A 65-year-old farmer re-presented 5 years after sustaining a midshaft prosthetic fracture of a previous long-stem revision hip replacement. He was treated with a proximal-loading short femoral stem, and did not require an extended trochanteric osteotomy for removal of the well-fixed distal implant. He was able to fully bear weight immediately postoperatively, and he remained pain-free without functional loss at the 42-month follow-up. CONCLUSION: This use of a modern short-stem prosthesis is a treatment option for a potentially complex prosthetic fracture in highly active patients, and it reduces intraoperative complexity...

Although additive manufacturing technologies, also known as 3D printing, were first introduced in the 1980s, they have recently gained remarkable popularity owing to decreased costs. 3D printing has already emerged as a viable technology in many industries; in particular, it is a good replacement for microfabrication technology. Microfabrication technology usually requires expensive clean room equipment and skilled engineers; however, 3D printing can reduce both cost and time dramatically. Although 3D printing technology has started to emerge into microfabrication manufacturing and medical applications, it is typically limited to creating mechanical structures such as hip prosthesis or dental implants...

OBJECTIVES: Since 2009, single-use (SU) ancillaries for total knee arthroplasty (TKA) and total hip arthroplasty (THA) have been marketed to replace reusable ancillaries. The concept is not innovative but their use in orthopedics is still uncommon. An assessment has been done for the use of SU ancillary in Assistance publique-hôpitaux de Paris with the consequences for the patient, the surgeon and the hospital. METHODS: A technical and a clinical review has been done with those devices in 2015...

Introduction: When treating periprosthetic joint infections with a two-stage procedure, antibiotic-impregnated spacers are used in the interval between removal of prosthesis and reimplantation. According to our experience, cultures of sonicated spacers are most often negative. The objective of our study was to investigate whether PCR analysis would improve the detection of bacteria in the spacer sonication fluid. Methods: A prospective monocentric study was performed from September 2014 to January 2016. Inclusion criteria were two-stage procedure for prosthetic infection and agreement of the patient to participate in the study...
