Femoral neck fractures (FNFs) in young adults are relatively uncommon but pose significant clinical and surgical challenges. Hip arthroplasty is rarely used as a treatment option in this population but has seen rising use over the previous decade. This study seeks to compare hip arthroplasty outcomes among young adult patients in the United States admitted with FNF by evaluating hip hemiarthroplasty (HHA) and total hip arthroplasty (THA). Using the National Inpatient Sample (NIS) data, adult patients less than 50 years old who underwent HHA or THA from 2016 to 2020 were analyzed. Both groups' postoperative length of stay (pLOS), total hospital charges, and prosthesis-related complications (PRCs), including mechanical loosening (ML), prosthesis dislocation (PD), and periprosthetic fracture (PPF), were analyzed and compared. Out of 174,776,205 hospitalizations between 2016 and 2020, 15,590 young adult patients had FNF, and 2970 patients (2.18%) underwent hip arthroplasty (1195 HHAs and 1775 THAs). After controlling for demographic, clinical and hospital characteristics, HHA was associated with a 22.4% longer pLOS compared to THA [rate ratio: 1.224, 95% CI: 1.183 to 1.266; < 0.001]. Patients in the HHA group also had higher odds of PPF (aOR: 9.06, 95% CI: 4.21, 19.48; < 0.001). Conversely, patients in the THA group had higher odds of PD (aOR: 6.00, 95% CI: 1.78, 20.24; =0.004). There was no statistically significant difference in total hospital charges between the groups [cost ratio: 1.03, 95% CI: 0.995 to 1.075; =0.092]. Among young adults with FNF undergoing hip arthroplasty, HHA is associated with a longer postoperative hospital stay and higher risk of PPF as a major early complication, while THA is associated with a higher risk of PD. Financial burden is comparable for both procedure groups. When hip arthroplasty is a preferred treatment for FNFs, individual patient factors are important considerations that should guide the choice of procedure.

This project aimed to explore the experiences of occupational therapists working in a specialist orthopedic hospital. Semi-structured interviews were carried out with eight occupational therapists working with total hip replacement patients, in an orthopedic hospital within the United Kingdom National Health Service (NHS) as part of a service review project. The data was recorded and transcribed and analyzed using the Reflexive Thematic Analysis.

Background: Valgus osteotomy is a femoral head-preserving surgery to treat femoral neck non-union in young, active patients. The traditional approach, however, causes medialisation of the femoral shaft during valgus correction, which alters femoral anatomy and complicates conversion to total hip arthroplasty if head osteosynthesis fails. This study aims to outline a novel surgical technique, medial opening wedge valgus intertrochanteric osteotomy (VITO), and evaluate its clinical and radiographic outcomes, focusing on restoring hip biomechanics and improving union rates.

Purpose: Aseptic loosening (AL) of prostheses is a complex and multi-factorial consequences characterized by nonspecific hip start-up pain, impaired gait, or ambulation. The AL of acetabular components associated with femur prostheses can lead to challenges in accurate diagnosis and suitable therapy, potentially resulting in disaster consequence. This study reported revision of in four cases with AL of acetabular components associated with or without femur prostheses after underwent primary total hip arthroplasty.

Background Outpatient joint arthroplasty (OJA) of the hip and knee is becoming increasingly popular within the orthopedic community. Most evidence regarding the safety and feasibility of OJA has been gathered from the perspectives of surgeons and healthcare organizations. However, the success of these pathways also hinges on patients feeling safe and adequately prepared to return home.
