Background: The current dilemma of osteosarcoma treatment is the resistance of chemotherapeutic drugs after long-term usage, which also introduces life-threatening side effects.

Methods And Results: To minimize chemoresistance in osteosarcoma patients, the authors applied shock waves (SWs) to human osteosarcoma MNNG/HOS cells, then evaluated the cell viability and extracellular ATP levels, and further investigated the effect of SWs on cisplatin (DDP) cytotoxicity in MNNG/HOS cells. The authors' results showed that 400 SW pulses at 0.

Background: Although tibial shaft fractures are the third most common long bone fractures in children after the forearm and femur, nonunion of these fractures are rare in the pediatric population.

Case Report: Despite seldom seen, tibial nonunion is very complex and it is also a devastating complication of tibial fracture especially when infected. Numerous methods have been employed to treat pediatric tibial nonunion, but there is no consensus.

Introduction: The efficacy of the most commonly used interventions for clavicle fractures remains controversial. These interventions are: open reduction and plate fixation (ORPF), non-surgical intervention (NSI), and use of an intramedullary nail (IMN). In adult patients with clavicle fractures, choosing which intervention might be best is challenging.

Background: The purpose of this meta-analysis was to comprehensively collect randomized controlled trials (RCTs) to assess the clinical efficacy of intrathecal morphine (ITM) versus local infiltration analgesia (LIA) in the treatment of total knee and hip arthroplasty patients.

Methods: Relevant studies were identified from the Embase, PubMed, Cochrane Library, Web of Science, Wanfang, and Chinese National Knowledge Infrastructure (CNKI) databases. We also reviewed the references of all identified articles to identify additional studies.

Rationale: It is challenging to visualize and reduce a posterolateral tibial plateau fracture through an anterolateral approach as the tibial plateau fragments are often covered by the fibular head and ligamentous structures.

Patient Concerns: In this case report, we describe a patient with a depression fracture of the posterolateral quadrant combined with a split fracture of the posteromedial quadrant and an avulsion fracture of the tibial intercondylar eminence.

Diagnoses: Tibial plateau fracture(AO type 41-B3).

Article Synopsis
  • Clavicle fractures, particularly in the midshaft, are common injuries that can be treated with evolving surgical methods, which tend to yield better outcomes compared to conservative approaches.
  • A specific case of a comminuted midshaft clavicle fracture was presented, featuring a bone fragment that was separated from the main fracture by soft tissue.
  • The authors developed a new double ligature technique using absorbable sutures, which has been successfully applied in over 50 cases over 7 years with good outcomes and no reported complications, suggesting this technique should be widely adopted.

Anatomical reduction and rigid fixation of acetabular posterior wall fractures extending to the acetabular roof proves challenging because of the big bony fragment and muscular obstruction to accessing this region. This report describes a novel reconstructive technique in a patient with an acetabular posterior wall fracture involving the acetabular roof. Both the standard Kocher-Langenbeck approach and a greater trochanter osteotomy technique were used.

Rationale: Anatomical characteristics, such as subcutaneous position and minimal muscle cover, contribute to the complexity of fractures of the distal third of the tibia and fibula. Severe damage to soft tissue and instability ensure high risk of delayed bone union and wound complications such as nonunion, infection, and necrosis.

Patient Concerns: This case report discusses management in a 54-year-old woman who sustained fractures of the distal third of the left tibia and fibula, with damage to overlying soft tissue (swelling and blisters).

Posterior hip dislocation with concomitant femoral fracture is very rare. Here, we report a rare case of a 43-year-old man who was injured in a car accident. The patient sustained right posterior hip dislocation with concomitant right acetabular transverse and posterior wall fracture, ipsilateral femoral shaft fracture, and contralateral proximal femoral fracture (AO type 31-A3).

Background: Cannulated screws (4.0 mm) provide inter-fragmentary compression and stability to fractures. A guide wire is used to define the screw trajectory and hold the fracture fragment while the screw is being inserted.

Posterior shoulder dislocation is a rare entity in clinical practice. The FARES (Fast, Reliable, Safe) method is a well-validated, effective, and rapid approach to achieve reduction of anterior shoulder dislocation, but its use for posterior shoulder dislocation has not been reported previously. A 46-year-old man was admitted to our hospital with acute posterior shoulder dislocation due to a fall experienced while inebriated.

Objective: To compare efficacy between the modified tension band technique and the parallel titanium cannulated lag screw technique for the transverse patella fracture.

Methods: Seventy-two patients were retrospectively analyzed aged 22 to 79 years (mean, 55.6 years) with transverse patella fractures, among whom 37 patients underwent the modified tension band and 35 patients received the titanium cannulated lag screw.

Virus-induced signaling adaptor (VISA) is essential for host innate immune responses against double-stranded RNA viral infection and viral replication. It is an adaptor that activates the transcription factors nuclear factor kappaB (NF-kappaB) and interferon regulatory factor 3 (IRF3) that regulate the expression of type I interferons. The localization of VISA to the outer membrane of mitochondria and the cellular consequences of its activation implicate this protein in the cellular etiology of neurodegenerative disorders.
