PURPOSE: There is no consensus on ideal short femoral stem design. A classification system proposed by Feyen and Shimmin divides short stems in two types according to femoral neck osteotomy levels: subcapital (IIIA) and standard (IIIB). The study aims to determine which design type is more successful in restoring native biomechanical parameters and whether stem type has an impact on clinical results. METHODS: In this retrospective comparative study, patients that have undergone short stem hip arthroplasty were evaluated according to stem types: type IIIA (n = 52, 66...

BACKGROUND: Selecting the optimal size of components is crucial when performing a primary total hip arthroplasty. Implanting the accurate size of the acetabular component can occasionally be exacting, chiefly for surgeons with little experience, whilst the complications of imprecise acetabular sizing or over-reaming can be potentially devastating. AIM: To assist clinicians intraoperatively with a simple and repeatable tip in elucidating the ambivalence when determining the proper acetabular component size is not straightforwardly achieved, specifically when surgeons are inexperienced or preoperative templating is unavailable...

BACKGROUND: Advances in implant material and design have allowed for improvements in total knee arthroplasty (TKA) outcomes. A cruciate retaining (CR) TKA provides the least constraint of TKA designs by preserving the native posterior cruciate ligament. Limited research exists that has examined clinical outcomes or patient reported outcome measures (PROMs) of a large cohort of patients undergoing a CR TKA utilizing a kinematically designed implant. It was hypothesized that the studied CR Knee System would demonstrate favorable outcomes and a clinically significant improvement in pain and functional scores...

PURPOSE: The purpose of this study is to compare the difference of results between two methods of femoral box osteotomy adopted by two designs of posterior stabilized total knee prostheses. PATIENTS AND METHODS: Retrospective analysis of the results of two groups of patients operated upon using two primary PS TKA systems, PFC Sigma (DePuy Synthes, Johnson and Johnson®) and Genesis II prosthesis (Smith and Nephew®), with an average of five year follow-up was done...

INTRODUCTION: Dual-mobility (DM) implants for total hip arthroplasty (THA) have gained popularity due to their potential to reduce hip instability and dislocation events that may lead to revision surgery. These implants consist of a femoral head articulated within a polyethylene liner, which articulates within an outer acetabular shell, creating a dual-bearing surface. Our study aimed to report our observations on the survivorship of a novel DM implant for primary total hip arthroplasty at two years...

Introduction Hip fractures in the elderly constitute a significant health concern, and their incidence is on the rise. It has been reported that intertrochanteric femoral fractures comprise a large portion of hip fractures, and they are especially prevalent among women. Over 75% of these types of fractures in the elderly occur as a result of simple falls. Surgical intervention must be performed for these fractures to expedite the healing process in patients. The application of a proximal femoral nail (PFN) is conducted using a minimally invasive technique after the fracture has been reduced using closed techniques...

BACKGROUND: Many patients with metastatic bone disease (MBD) of the femur undergo prophylactic surgical fixation for impending pathologic fractures; intramedullary nailing (IMN) being the most common fixation type. However, surgeons often question if IMN fixation provides sufficient improvements in mechanical strength for particular metastatic lesions. Our goal was to use patient-specific finite element (FE) modeling to computationally evaluate the effects of simulated IMN fixation on the mechanics of femurs affected with MBD...

Introduction Intracapsular neck of the femur fractures are some of the most common fragility fractures with significant morbidity and mortality. Cemented hemiarthroplasty is the standard treatment in most cases. Restoring the horizontal offset and leg length is important to optimize the outcome of hip hemiarthroplasty. Preoperative templating based on a scaled radiograph is common prior to total hip arthroplasty surgery to achieve optimum offset and leg length. It is not routine to have scaled radiographs available prior to a hemiarthroplasty surgery...

PURPOSE: Headless compression screws (HCS) have a variable thread pitch and headless design enabling them to embed below the articular surface and generate compression force for fracture healing without restricting movement. Locking screws have greater variety of dimensions and a threaded pitch mirroring the design of the HCS. The objective of this study is to determine whether locking screws can generate compression force and compare the compressive forces generated by HCS versus locking screws...

Lower extremity amputation (LEA), particularly in patients with diabetes or peripheral vascular disease, often results in complications such as surgical site infections (SSIs) and wound dehiscence. This study examined whether utilizing the portable and user-friendly PICO system (Smith and Nephew Medical Ltd, Hull, UK) as incisional negative-pressure wound therapy can reduce post-LEA complications. This study was conducted at a Japanese tertiary medical center and involved a retrospective analysis of LEA cases (n = 32) between January 2021 and December 2022...

INTRODUCTION: Oxidized Zirconium (OXINIUM™) is a metal alloy with a ceramic surface, utilized to increase the longevity of knee and hip implantations and reduce polyethylene wear. Polyethylene-based spacers are effective in infection control and prosthetic stability. Therefore, understanding the interactions between the polyethylene spacer and metallic counterparts is essential in surgical decision-making. Furthermore, understanding how patients may present when catastrophic failure of these components arises is imperative...

INTRODUCTION: With an increasing life expectancy, there has been an increase in the incidence of intertrochanteric fractures. These fractures in the elderly are disabling and have a tremendous impact on the healthcare system. Despite substantial improvements in implant design and surgical techniques, high failure rates have been observed, varying with the severity of the fracture and the type of fixation. Intramedullary nails have become popular in recent times, especially in unstable fractures...

INTRODUCTION: In today's world, high-cost procedures are being examined, and alternative procedures are being developed. In this context, one frequently examined procedure is total knee replacement. PURPOSE: This study aims to examine the three different closure techniques used in total knee replacement. METHODS: This study is a prospective randomized controlled study. Two hundred participants who underwent total knee replacement surgery, were included in the study...

BACKGROUND: Little is known about the stability of adjustable-loop devices (ALDs) for anterior cruciate ligament (ACL) reconstruction (ACLR). PURPOSE: To evaluate the stabilization behavior of 3 different types of ALDs for all-inside ACLR in a full-construct surgical technique-based manner. STUDY DESIGN: Controlled laboratory study. METHODS: The femoral and tibial devices of Ultrabutton (Smith & Nephew), Infinity (Conmed), and TightRope II (Arthrex) were applied to quadrupled bovine tendon grafts (n = 8 each) with tibial-sided traction applied (350 N) for graft tensioning in a simulated fully extended knee...

PURPOSE: Radiofrequency ablation is an increasingly used surgical option for ablation, resection and coagulation of soft tissues in joint arthroscopy. One of the major issues of thermal ablation is the temperature monitoring across the target areas, as cellular mortality is a direct consequence of thermal dosimetry. Temperatures from 45 °C to 50 °C are at risk of damage to chondrocytes. One of the most reliable tools for temperature monitoring is represented by fiber optic sensors, as they allow accurate and real-time temperature measurement via a minimally invasive approach...

The combination of obesity, diabetes mellitus (DM), and reduced mobility due to spina bifida can contribute to an increased risk of osteomyelitis. Spina bifida, a congenital defect of the spinal cord, causes vertebral column deformities and neurological impairment. Obesity can lead to increased pressure and stress on the bones and joints, as well as poor circulation and immune dysfunction, including neutrophil migration disorders. Similarly, DM can also contribute to poor circulation and inadequate immune function...

INTRODUCTION: Although current antiretroviral therapy allows most people with HIV (PWH) to experience normal longevity with a good quality of life, an HIV cure remains elusive due to HIV reservoir formation within deep tissues. An HIV cure remains highly desirable to the community of PWH. This study reports on the perceived risks and benefits of participation in the Last Gift study, a study aimed at characterizing HIV reservoirs via post-mortem autopsy, among PWH at the end of life (EOL) and their next-of-kin (NOK)/loved ones...

INTRODUCTION: Comparison between fully hydroxyapatite (HA)-coated stems with differing geometry are lacking in the total hip arthroplasty (THA) literature. This study aimed to compare femoral canal fill, radiolucency formation, and 2-year implant survivorship between two commonly used, HA-coated stems. METHODS: All primary THAs performed with two fully HA-coated stems (Polar stem, Smith&Nephew, Memphis, TN and Corail stem, DePuy-Synthes, Warsaw, IN) with a minimum 2-year radiographic follow-up were identified...
