What are the clinicopathological changes in calcaneal fractures?

Rupture of the extensor tendon after volar plate fixation remains a major problem in the repair of distal radius fractures. The most commonly affected tendon is the extensor pollicis longus (EPL) tendon, as it is confined within the EPL groove. The reported incidence of EPL tendon rupture after vola

Displaced comminuted fractures of the distal humerus in adults are a difficult problem due to the complex anatomy of the elbow joint, small fracture fragments, and limited amount of subchondral bone. The lateral and medial columns of the distal humerus form a stable triangular frame.

To reproducibly obtain stable fixation in the setting of osteoporotic or comminuted fractures, the parallel plate technique for the treatment of distal humeral fractures is based on the principle of enhancing the fixation of distal fractures. The key to the stability of this fixation structure is th

The meniscus is a meniscus-shaped fibrocartilage with a triangular cross-section located between the tibial condyle and the plateau, which significantly improves femoro-tibial joint consistency and plays an important role in knee joint dynamics.The meniscus is a meniscus-shaped fibrocartilage with a

Hip fractures are estimated to affect 500,000 adults in the United States each year. They have a tremendous impact on quality of life, currently accounting for 3-7% of in-hospital mortality and a one-year mortality rate of 19.4-58%. Approximately half of all hip fractures are intertrochanteric (IT)

Periprosthetic fractures of the proximal femur are a serious problem in hip arthroplasty. The reported incidence is 3.5% 20 years after initial implantation and increases with the incidence of joint replacements. Intraoperative fractures are often associated with uncemented stems. More commonly, fra

Proximal humerus fractures are one of the most common fractures in trauma orthopedics, and most proximal humerus fractures are low-energy osteoporotic fractures in the elderly.Although the majority of proximal humerus fractures can be treated conservatively, 10-15% of fractures still require surgica

Posterior shoulder instability is usually caused by traumatic posterior dislocation or repetitive minimally invasive injury during exercise or other activities, with an annual incidence rate of 4.64 cases per 100000 people per year. Several surgical techniques for the treatment of posterior shoulder

Metacarpophalangeal fracture is a common fracture in hand trauma, accounting for about 1/4 of the patients with hand trauma. because of the delicate and complex structure of the hand and the fine motor function, the management of hand fractures is far more important and technically complex than the treatment of other long tubular fractures.
