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.

Intramedullary tibial nailing: access and alignment, anterior knee pain

Clavicle fractures are one of the most common fractures, accounting for 3% of all fractures. Historically, it has been treated non-operatively, but the results have not always been positive. Non-operative treatment can lead to complications such as pain, malunion, and thoracic outlet syndrome. Due to improvements in surgical fixation techniques, many surgeons have opted to use surgical fixation to treat displaced clavicle fractures.

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

Choice of internal fixation versus joint replacementAt present, it is generally believed that hollow nail internal fixation for femoral neck fracture has the advantages of short operation time, little trauma and low cost, but most elderly patients are accompanied by osteoporosis, so the stability of

Elastically stabilized intramedullary nails (ESINs) are a common method for surgical stabilization of long bone fractures in children. It is widely used to treat unstable fractures of the radius, ulna, femur, and occasionally the tibia and humerus. It is also used to treat pathological fractures of

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

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

Cervical implants are devices that surgeons use to decompress and stabilize the neck. These devices can be implanted from the front (front) of the spine or from the back (back).
