OBJECTIVE: Total knee arthroplasty (TKA) is an established surgical technique and is the standard treatment for degenerative knee joint diseases. However, severe pain after TKA makes it difficult for many patients to perform early postoperative rehabilitation and functional exercise, which might result in subsequent unsatisfactory recovery of knee joint function and great reduction in patients' satisfaction and quality of life. Orthopaedic surgeons have tried a large variety of analgesics and analgesic modes to relieve patients' pain after TKA...

OBJECTIVE: Turnover of cartilage endplate extracellular matrix (ECM) may play an important role in disc degeneration and low back pain (LBP). However, the expression pattern of pro-inflammatory factors, matrix metalloproteinases (MMP), and tissue inhibitors of metalloproteinases (TIMP) in the cartilage endplates (CEP) of intervertebral discs (IVD) is not understood. We aimed to examine the transcriptional levels of MMP, TIMP, and interleukins (IL), and the correlations between them. METHODS: Thirty degenerated cartilage endplate samples from patients with LBP who underwent lumbar fusion surgery were included in the degenerated group...

OBJECTIVE: Iatrogenic radial nerve injury is a great challenge for orthopaedic surgeons who deal with distal-third diaphyseal humerus fractures. Conventional open reduction and internal fixation (ORIF) remains the gold standard, but complications such as nonunion and iatrogenic radial nerve injury still occur. We fixed the fractures with a lateral locking compression plate (LCP) subcutaneously after small incision reduction to protect the radial nerve. This study reports the clinical and radiographic outcomes of our modified method...

The clinical incidence of tumors in the manubrium is not high. Regardless of whether the tumor is primary or metastatic, the tumor should be completely removed as long as the patient is able to tolerate the surgery. This procedure can lead to sternal defects. Deciding on the method of defect reconstruction is a critical problem that clinicians face. In this , to reduce the limitations of the patient's upper body movement after surgery due to the inflexibility in the connections of the sternal prosthesis, we created a prosthesis using a computer-assisted design method and a 3-D technique, to completely preserve the agility of the sternum and maximize the patient's post-operational movement...

OBJECTIVES: Knee osteoarthritis (OA) is a prevalent disease in the elderly, causing pain and contributing to poor quality of life. Surgical intervention, such as knee arthroplasty, can be used in those with end-stage knee OA. Total knee arthroplasty (TKA) is one of the most common surgical procedures for end-stage knee OA, with promising clinical outcomes. However, a large proportion of patients with isolated compartment OA can be treated with unicompartmental knee arthroplasty (UKA) instead...

OBJECTIVES: Femoral intertrochanteric fractures are among the most common fractures in the elderly. There are various classification systems in intertrochanteric fractures. The aim of these classification systems is to help surgeons choose an appropriate treatment. The treatment of femoral intertrochanteric fractures depends on the results of a stability evaluation using imaging studies. However, it is difficult to evaluate the true fracture line using plain X-ray films, especially on the sagittal plane and for intertrochanteric fractures with complex morphologies...

Gorham-Stout disease (GSD) is an extremely rare bone condition of unknown etiology characterized by spontaneous and progressive resorption of bones. GSD can occur at any age and is not related to gender, genetic inheritance, or race. Any part of the skeleton can be affected and the symptoms correlate with the sites involved. The diagnosis of GSD is established based on the combination of clinical, radiologic, and histologic features after excluding other diseases. Because of its rarity, current knowledge is limited to case reports and there is no agreement on the best strategy for treatment...
