A 17-year-old male was ejected from the motorcycle and brought to the Emergency Department with bilateral hip dislocation and absence of pelvic or femur fractures or sciatic nerve injury. Closed reduction and postreduction examination were performed with a bilateral stable full range of motion in all directions.

Introduction And Importance: Neglected posterior hip dislocations in adults are rare, particularly when untreated for years. In developing nations, patients often rely on traditional bone setters, leading to delayed diagnosis and increased complications. Adult hip dislocations carry a higher risk of avascular necrosis and require complex treatments.

Article Synopsis
- The study aimed to compare the Modular Dual Mobility (MDM) hip system and large femoral heads (LFHs) in revision total hip arthroplasties (THAs), focusing on risks like dislocation and metal-related complications.
- Researchers analyzed 299 revision THAs and found that the MDM group had a significantly lower rate of re-revision for dislocation (99% survival) compared to the LFH group (91% survival), with increased risks for LFH patients.
- Overall, THAs utilizing the MDM construct demonstrated a safer profile, particularly in reducing re-revisions related to dislocation and had no reported issues with metallosis or corrosion.
Application of additive manufacturing TaBw01 porous tantalum rod in ARCO stage II osteonecrosis of the femoral head.

Purpose: This study aims to investigate the suitable surgical strategies for applying TaBw01 porous tantalum rod across different stages of osteonecrosis of the femoral head (ONFH).
Methods: TaBw01 tantalum rods were fabricated using type FTaY-1 tantalum powder via the foam impregnation-sintering method. Mechanical testing with the Instron 8801 universal testing machine and finite element analysis (FEA) assessed single tantalum rod implantation and impaction bone grafting combined with rod implantation.

Aims: The primary aims of this study were to determine the time to sonographic correction of decentred hips during treatment with Pavlik harness for developmental dysplasia of the hip (DDH) and investigate potential risk factors for a delayed response to treatment.
Methods: This was a retrospective cohort study of infants with decentred hips who underwent a comprehensive management protocol with Pavlik harness between 2012 and 2016. Ultrasound assessments were performed at standardized intervals and time to correction from centring of the femoral head was quantified.
The risk of dislocation in dual-mobility versus 36 mm heads in primary total hip arthroplasty for osteoarthritis.

Musculoskeletal Tumor Section, Department of Orthopedic Surgery, Copenhagen University Hospital Rigshospitalet, Copenhagen, Denmark.
Aims: Dislocation is a major concern following total hip arthroplasty (THA) for osteoarthritis (OA). Both dual-mobility components and standard acetabular components with large femoral heads are used to reduce the risk of dislocation. We investigated whether dual-mobility components are superior to standard components in reducing the two-year dislocation and revision risk in a propensity-matched sample from the Danish Hip Arthroplasty Register (DHR).
