Humeral stem fractures (HSF) are relatively common, accounting for approximately 1% to 5% of all fractures. The annual incidence is 13 to 20 per 100,000 people and has been found to increase with age.HSF has a bimodal age distribution, with the first peak occurring in men between 21 and 30 years of

Patellofemoral instability (PFI) is common in children's knee joint injuries. PFI is caused by the imbalance of patellar dynamic relationship in femoral trochlear groove. External dislocation of the patella is the extreme of PFI, which is caused by the injury of the medial stabilizer, resulting in the patella hitting the lateral femoral condyle.

Fractures are usually accompanied by injuries to other parts of the body. In the whole process of treatment, patients must be treated as a whole.

Unicompartmental knee arthroplasty (UKA) is a surgical alternative to total knee arthroplasty (TKA) for the treatment of unicompartmental osteoarthritis. However, data on the failure rate of UKA show a 7-year survival rate of 74%, which is significantly lower than that of TKA (92%). Although patients' own factors increase the risk of failure, such as younger patients and higher body mass index (BMI) may increase the risk of UKA failure, surgical technical errors have been considered as important risk factors for early failure. In UKA, it is challenging to achieve optimal prosthetic alignment and overhang (overhang). The tibial prosthesis should be sized and implanted in a manner that minimizes soft tissue irritation, and a medial tibial overhang of more than 3 mm has been shown to be a significant risk factor for decreased Oxford Knee Score (OKS) and increased pain. The primary objective of this study was to evaluate the overall clinical and imaging outcomes of UKA.

Femoral neck fracture is one of the most commonly encountered orthopedic injuries in clinical practice, with the majority of elderly patients accounting for more than 50% of hip fractures. According to statistics, the incidence of femoral neck fractures has gradually increased in recent years, with

Closed reduction is the minimally invasive technique that can be used for stable fractures of extremities with no loss of blood flow, no risk of infection, fast functional recovery, significantly reduced medical costs, and can be used for closed reduction hollow nail and intramedullary pin fixation treatment of various unstable fractures, such as femoral neck fractures, femoral stem fractures, tibiofibular fractures, humeral stem fractures, etc., eliminating the destruction of blood flow by incisional reduction.

Removal of intramedullary nails is a routine procedure, as each manufacturer provides appropriate removal tools. However, the actual need to remove the complete intramedullary nail is rare. Once the intramedullary nail ruptures, the situation becomes especially tricky.

Often, the intramedullary nail may need to be removed before a nonunion requires revision surgery. However, once the fracture has healed, the removal of the intramedullary nail has become controversial.

What is intramedullary nail?Intramedullary nailing is surgery to repair a broken bone and keep it stable. The most common bones fixed by this procedure are the thigh, shin, hip, and upper arm. A permanent nail or rod is placed into the center of the bone. It will help you be able to put weight on th

The femur or thigh bone is the largest bone in the body. The femoral stem or diaphysis is the long, straight middle part of the femur. Fractures of the femoral stem are usually the result of high-energy trauma, such as a road traffic accident.Fractures of the femoral stem may be closed, with the tis
