Periprosthetic osteolysis is a major long-term complication of total joint replacement. A series of biological reactions caused by the interaction of wear particles at the prosthesis bone interface and surrounding bone tissue cells after artificial joint replacement are vital reasons for aseptic loosening. Disorder of bone metabolism and aseptic inflammation induced by wear particles are involved in the occurrence and development of aseptic loosening of the prosthesis.

Osteoporosis is a bone metabolic disorder characterized by decreased bone density and deteriorated microstructure, which increases the risk of fractures. The imbalance between bone formation and bone resorption results in the occurrence and progression of osteoporosis. Osteoblast-mediated bone formation, osteoclast-mediated bone resorption and macrophage-regulated inflammatory response play a central role in the process of bone remodeling, which together maintain the balance of the osteoblast-osteoclast-macrophage (OB-OC-MΦ) axis under physiological conditions.

The homeobox gene family encodes transcription factors that are essential for cell growth, proliferation, and differentiation, and its dysfunction is linked to tumor initiation and progression. Sine oculis homeobox (SIX) belongs to the homeobox gene family, with SIX3 being a core member. Recent studies indicate that SXI3 functions as a cancer suppressor or promoter, which is mainly dependent on SIX3's influence on the signal pathways that promote or inhibit cancer in cells.

Rationale: Avascular necrosis (AVN) of the metacarpal head is rare, and there is no clear consensus on treatment. The main aim of this study was to discuss the possible pathologic-mechanics of its development, epidemiology, radiographic features, and outcome after conservative treatment.

Patient Concerns: A 14-year-old male with a history of fractures in little finger complained of right-hand pain with a limited range of motion for 1 month.

Our study aimed to determine how lncRNA DANCR, miR-320a, and CTNNB1 interact with each other and regulate osteogenic differentiation in osteoporosis. qRT-PCR and western blotting were performed to determine the expression of DANCR, miR-320a, CTNNB1, and the osteoporosis- or Wnt/β-catenin pathway-related markers T-cell factor 1 (TCF-1), runt-related transcription factor 2 (RUNX2), alkaline phosphatase (ALP), osteocalcin (OCN), and osteopontin (OPN). Interactions between CTNNB1, DANCR, and miR-320a were predicted by bioinformatics approaches and validated using a luciferase assay.

Background Aims: Osteoporosis (OP) is a common bone metabolic disease with a high incidence. Our study aimed to explore the pseudogene PTENP1/miR-214/PTEN axis to modulate the osteoclast differentiation in osteoporosis.

Methods: Patients with osteoporosis were recruited in our study, and RANKL-induced osteoclast differentiation and ovariectomy-induced osteoporosis mouse model were established in vitro and in vivo, respectively.

Objective: To determine whether differences exist in patients' subjective feelings, daily life, and surgical satisfaction between those who underwent surgery for developmental dysplasia of the hip (DDH) using patient-specific instruments (PSIs) and those who underwent traditional surgical total hip arthroplasty (THA).

Methods: We selected 30 adult patients with various types of DDH who underwent surgery during 2016-2017 at our hospital. The patients were divided into PSI surgery group and the traditional surgery group.

Three-dimensional (3D) printing technology, virtual reality, and augmented reality technology have been used to help surgeons to complete complex total hip arthroplasty, while their respective shortcomings limit their further application. With the development of technology, mixed reality (MR) technology has been applied to improve the success rate of complicated hip arthroplasty because of its unique advantages. We presented a case of a 59-year-old man with an intertrochanteric fracture in the left femur, who had received a prior left hip fusion.

Article Synopsis
  • The article reviews recent updates in revision total knee arthroplasty (RTKA), emphasizing its importance as a common treatment for knee diseases and the challenges faced after primary surgeries.
  • Patients may need RTKA due to issues like mechanical wear, implant loosening, infection, or stiffness, yet the outcomes are often less favorable compared to primary procedures.
  • Current management options include various types of bone grafting and specialized implants, but they come with their own complications, highlighting the need for innovative approaches to enhance patient outcomes and cost-effectiveness.

Background: Osteogenic differentiation of bone marrow mesenchymal stem cells (BMSCs) is of much significance for bone formation, the imbalance of it would result in osteoporosis and other pathological bone defects. Increasing evidences showed that long non-coding RNAs (lncRNAs) and miRNAs played vital roles in the regulation of osteogenic differentiation. LncRNA KCNQ1OT1 was often regarded as an imprinted lncRNA and was related to tumor progression, while its function in osteogenic differentiation remained unclear.

Article Synopsis
  • Periprosthetic osteolysis, a common issue after joint replacement surgeries, is caused by wear particles and inflammation affecting macrophages.
  • This study explored the effects of curcumin, a natural compound, on macrophages exposed to polyethylene particles, using both lab tests on isolated macrophages and a mouse model.
  • Results showed that curcumin not only promotes cholesterol efflux in macrophages and helps maintain a non-inflammatory state but also leads to better bone density and reduced inflammation in the treated mice.

Objective: To explore the value of detecting bacterial 16S rRNA with 23S rRNA in the diagnosis of periprosthetic joint infection (PJI).

Methods: A prospective study was conducted among 67 patients with previous total hip arthroplasty (THA) undergoing a reoperation for infection (23 patients) or aseptic loosening (44 patients). Bacterial 16S rRNA and 23S rRNA in the interface membrane were detected by real-time PCR and their value in diagnosis of PJI was assessed.

Objective: To evaluate the effect of chronic filariasis patients with lymphedema after comprehensive cared.

Methods: A total of 386 chronic filariasis patients with lymphedema received the comprehensive care including soaking feet by TCM, washing feet by single Chinese medicine or clear water, preventing and eliminating invasive wound, physical training, raising the limb, and wearing suitable shoes. The attack frequency of inflammation of lymphatic vessels, the stage of lymphedema disease, and leg circumference were observed before and after the care.

Despite substantial advances in orthopaedic surgery, bone nonunion is still a matter of debate for orthopaedic surgeon to provide optimal options on treatment of nonunion. Negative pressure therapy has already been successfully used in dealing with complex kinds of soft tissue healing. Some studies show that negative pressure can induce mesenchymal stem cells to differentiate into osteoblasts and others suggest that there are some mesenchymal-like cells existing in the nonunion tissue which can be re-activated and transformed into osteoblasts under some circumstance.

Objective: To develop a new internal fixation device and the matching tools for subtrochanteric fracture, investigate the biomechanical features thereof, and compare its effects with those of other instruments.

Methods: A new internal fixation device, static three dimensional screw-plate system: (STDSP) was developed based on the anatomical parameters and the biomechanical characteristics of proximal femur and combined with the biomechanical advantages of the model of three-dimensional plate and multiple-screws plate fixation. Sixteen paired cadaveric adult femurs were randomly divided into 2 equal groups: fracture healing group undergoing insertion of implant and then taking out thereof with a nail left, and fracture group with a trapezoid defect to mimic subtrochanteric fracture 4 of which were fixed with dynamic hip screw (DHS) and STDSP or Gamma nail and STDSP.
