hip replacement posterior

Femoral nerve palsy (FNP) is a debilitating and relatively rare complication of total hip replacement, which can worsen the functional prognosis. Various surgical approaches, including posterior, lateral, and anterior, are employed in total hip arthroplasty (THA), and the chosen approach can influence which nerve is affected. There is currently a lack of recent research on the prevalence of FNP and its typical course of recovery. In this clinical case, we report a rare incidence of FNP that presented as a complication of primary THA in a patient with end-stage osteoarthritis secondary to developmental dysplasia of the hip (DDH)...

Bilateral hip dislocations are among the rarest traumatic incidents. We report a case of a 45-year-old, opium-addicted man with bilateral posterior hip dislocation and bilateral femoral head fractures proximal to the fovea with more comminution on the left side. After an unsuccessful closed reduction attempt, surgical reduction and internal fixation of the left and right femoral heads were performed on admission and 72 hours later. He was readmitted because of acute deep vein thrombosis (DVT) on the left side after six weeks and left femoral head avascular necrosis (AVN) after 14 months...

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...

PURPOSE: To evaluate the accuracy and reproducibility of a patient-specific, customized individually made (CIM) total knee replacement (TKR) using the ORIGIN® prosthesis. METHODS: This was a prospective study conducted at a University Hospital from January 15, 2019, to April 30, 2021. The study included patients planned for an ORIGIN® CIM TKR procedure. Exclusion criteria included revision surgery, severe deformity, stiffness, or laxity. Evaluations were carried out using computed tomography scans performed 8 weeks preoperatively and 6 weeks postoperatively...

OBJECTIVE: To compare and analyze the early clinical effect of direct superior approach(DSA) and posterior lateral approach (PLA) in hemiarthroplasty for elderly patients with femoral neck fracture. METHODS: The clinical data of 72 elderly patients with femoral neck fracture who underwent hemiarthroplasty from January 2020 to December 2021 were retrospectively analyzed. Among them, 36 patients were operated through minimally invasive DSA including 10 males and 26 females with an average age of (82...

INTRODUCTION: A floating hip injury involving the acetabulum and femur, often complicated by hip dislocation, necessitates a timely and appropriate management strategy to preserve the extremity and patient well-being. CASE PRESENTATION: We present a case of a 20-year-old male with concurrent fractures of the acetabular posterior wall, a comminuted femoral shaft, and posterior hip dislocation. Reduction of the dislocated hip posed a challenge due to the femoral shaft fracture...

PURPOSE: The aim of this study was to identify if constitutional alignment and preoperative radiologic parameters determined whether medial gap balancing was required in mechanically aligned total knee arthroplasty (TKA). METHODS: Two hundred and sixty three patients with 394 consecutive knees who underwent primary TKAs were retrospectively analysed in this study. Selective sequential multiple needle puncturing (MNP) was performed for medial ligament balancing when required...

Introduction The prevalence of bilateral hip arthritis continues to rise. With the dramatic change in the practice of modern-day arthroplasty with standard operating protocols and guidelines in place to reduce the incidence of surgical site infection and peri-operative thromboembolic events, simultaneous bilateral total hip replacement (THR) has been considered a viable option to reduce morbidity. The efficacy of simultaneous bilateral THR with regard to patient outcomes and complications has been debated...

Femoral neck fracture (FNF) is a common and devastating injury in the elderly population. The incidence of FNF is expected to increase in the future, particularly in the aging population. The displaced intracapsular FNF is replaced with a reconstruction prosthesis. These treatment options typically include hemiarthroplasty (HA) or total hip arthroplasty (THA). Dislocation after THA can be a significant complication, leading to increased hospital costs and patient dissatisfaction. This narrative review aims to investigate the potential risk factors for dislocation following THA after FNF...

Appropriate post-operative (post-op) pain control has been shown to reduce length of stay and facilitate day case surgery. Periacetabular injection of bupivacaine is effective in pain reduction after hip arthroscopy. This study aims to evaluate the anterior superior iliac spine (ASIS) as an anatomical landmark to facilitate needle insertion prior to fluoroscopy. The meeting point derived from a vertical line one fingerbreadth distal to the ASIS and a longitudinal line from the greater trochanter (GT) was used as a landmark in 30 consecutive hip arthroscopy patients for periacetabular analgesia...

Arthroscopy and endoscopic hip surgery have attracted increasing attention in the orthopedic field. In the case of arthroscopy, portals and their relationships with neurovascular bundle structures at risk are well established. However, studies on endoscopic portals used for the repair of hamstring tendon injuries are insufficient. Hamstring injuries are the most common muscle injury in sports medicine, and up to 12% can present as a tendon rupture. Endoscopic surgery is advantageous because it has a lower rate of bleeding and avoids excessive handling of the gluteal muscles...

Periacetabular osteotomy (PAO) is a well-established surgical treatment for hip dysplasia. Few studies report risk factors for the development of superior ramus osteotomy non-union. The purpose of this investigation was to document the incidence and risk factors for this complication. We identified 316 consecutive hips that underwent PAO for symptomatic acetabular dysplasia with a minimum 1-year radiographic follow-up. We developed and validated a technique to measure the superior ramus osteotomy location on anterior-posterior (AP) pelvis radiographs and computed tomography...

INTRODUCTION: Although an autogenous graft has the highest rate of bone union to fill the void created in medial opening wedge high tibial osteotomy (MOWHTO), it also has some disadvantages, such as prolonged surgical time, donor site pain and morbidity. Two possible candidates for ideal grafts to replace autogenous grafts are allogeneic and synthetic graft, which are free from donor site pain and morbidity. However, previous reports comparing the clinical results of allogeneic to synthetic graft have been limited and controversial...

BACKGROUND: Postoperative dislocations following total hip arthroplasty (THA) are of concern. A higher risk of dislocation has been reported for the posterior approach (PA) compared to the anterior approach (AA). Dual mobility implants, larger head sizes, and elevated or face changing liners can reduce the risk for dislocation. It remains unclear whether the component selection is influenced by the surgical approach. METHODS: This is a retrospective study of 7,048 patients who underwent 7,460 primary THA with either AA or PA for primary hip osteoarthritis or osteonecrosis of the femoral head between 2019 and 2021...

PURPOSE: The aim of this systematic review and meta-analysis was to compare joint awareness in patients who underwent total hip arthroplasty (THA) via the anterior approach (AA) versus the posterior approach (PA). The hypothesis was that patients who underwent THA via AA would have better forgetfulness of the artificial joint. METHODS: A comprehensive search of major literature databases and bibliographic details was conducted to identify studies evaluating the forgotten joint score (FJS-12) in total hip arthroplasty (THA) patients operated through the anterior approach (AA) and posterior approach (PA)...

In the setting of chronic instability following total hip arthroplasty, implantation of a constrained acetabular liner may be warranted. We report on a patient who sustained a posterior prosthetic hip dislocation out of the constrained acetabular liner component (Stryker Trident [Kalamazoo, MI]), which had been previously replaced 2 months prior, and underwent a successful closed reduction in the emergency department. At 2-year follow-up, the patient's prosthetic hip has remained stable with no reported issues...

BACKGROUND CONTEXT: Recent studies suggest that ossification of the posterior longitudinal ligament (OPLL) is exacerbated by systemic metabolic disturbances, including obesity. However, although an increase in bone mineral density (BMD) measured at the lumbar spine has been reported in patients with OPLL, no studies have investigated the systemic BMD of patients with OPLL in detail. PURPOSE: We investigated whether patients with OPLL develop increased whole-body BMD...

BACKGROUND: Prosthetic joint infection(PJI) is a devastating complication of total hip arthroplasty (THA). This study aimed to determine if the anterior surgical approach (AP) influenced the incidence of early PJI in THA compared to posterior approach (PP). METHODS: Record linkage was performed between state-wide hospitalization data and a national joint replacement registry to identify unilateral THA performed via the AP or PP. Complete data on 12,605 AP and 25,569 PP THAs were obtained...

BACKGROUND: Advocates of robot-assisted technique argue that robots could improve leg length restoration in total hip replacement. However, there were few studies to compare the robot-assisted posterior approach (RPA) with conventional posterior approach (PA) THA and direct anterior approach (DAA) THA in LLD. This study aimed to determine whether robot-assisted techniques could significantly reduce LLD compared to manual DAA and manual PA. METHODS: We retrospectively reviewed the cohort of consecutive ONFH patients who underwent THA robot-assisted posterior, manual posterior, and manual DAA from January 2018 to December 2020 in one institution...

This study aimed to evaluate clinical outcomes based on patient-reported outcome measures and to analyze factors influencing patient dissatisfaction at 1 year after curved periacetabular osteotomy (CPO). This retrospective review involved 98 hips of 98 consecutive patients with symptomatic acetabular dysplasia who underwent CPO from March 2016 to June 2020. The clinical outcomes were evaluated based on the Japanese Orthopaedic Association Hip Disease Evaluation Questionnaire, the Medical Outcomes Study 36-Item Short-Form Health Survey and the Harris Hip Score...
