Management of Vancouver B3 Periprosthetic Femur Fracture Using a Modular Uncemented Long Femoral Stem Prosthesis With Cerclage Wiring Technique.

Periprosthetic fractures (PPF) of the femur in connection with total hip arthroplasty are becoming common and also frequently challenging to repair. Such patients typically are frail, elderly, and have osteoporosis. Owing to a scarcity of research there are no clear strategies for its effective management. However, the Vancouver classification may help in facilitating treatment decisions. For fractures around a loose femoral prosthesis (types B2 and B3), revision using a modular uncemented long stem, with or without additional fracture fixation, has been known to provide a reliable outcome. It is prudent to treat osteoporosis for fracture healing and to prevent further fractures. In this case report, we share our experience with the use of an uncemented modular long femoral stem prosthesis with a cerclage wiring technique for the management of Vancouver type B3 PPF of the left femur in a 63-year-old male patient. Revision arthroplasty using a long stem prosthesis with a cerclage wiring technique can provide better fixation, stability, and functional outcomes for the patient.

Outcome Analysis of Posterior Cruciate Ligament Injuries: A Narrative Review.

The primary posterior stabilizer of the knee is the posterior cruciate ligament (PCL), the largest intra-articular ligament in the human knee. One of the four primary ligaments of the knee joint, the PCL, serves to support the tibia on the femur. An extreme force applied anteriorly to the proximal tibia of the flexed knee results in trauma to the PCL. Dashboard injuries, which occur when the knee is driven into the dashboard after a collision with a motor vehicle, are frequent causes. Grade 1 and 2 acute injuries are often addressed conservatively due to the PCL's natural capacity for mending. If a grade 3 injury occurs, a cautious trial can be conducted on elderly or low-demand patients. When standard treatment for isolated grade 3 injuries has failed, surgery is advised. Single-bundle or double-bundle techniques using either transtibial tunnel or tibial inlay techniques are among the reconstruction approaches. Restoring the natural kinematics of the knee and forestalling persistent posterior and mixed rotatory knee laxity are the ultimate goals of treating PCL injuries through a personalized strategy. These injuries may become more common in the future as more people participate in sports. As a result of ongoing instability, discomfort, diminished function, and the emergence of inflammatory and degenerative disorders of joints, PCL rips are becoming more well-acknowledged as a cause of morbidity and decreased function.

Bilateral Kohler's Disease: A Case Report.

Kohler's disease is characterized by osteochondritis of the navicular bone due to various factors like the lack of blood supply and late ossification of the bone. In particular, it is a disease of the pediatric age group, which has male preponderance. It may present with bony pain unilaterally or, at times, be asymptomatic and diagnosed accidentally. Clinical presentation and radiological investigations are the mainstay of diagnosis. This self-limiting condition requires only symptomatic conservative management. A surgical approach is not yet indicated. One such case of bilateral Kohler's disease is presented in this report. Here, we discuss the disease's presentation, examination, treatment, and prognosis.

Aneurysmal Bone Cyst of the Head of the Fibula: An Unusual Presentation.

Bone cysts are tumor-like lesions of bone. These are primarily of two types: simple or unicameral and aneurysmal bone cysts (ABC). An aneurysmal bone cyst (ABC) is a blood-filled cyst that usually occurs over the metaphysis of long bones, flat bones, and vertebrae. The symptoms of these cysts include pain and swelling over the area. It may consist of pathological fractures as well. The cyst is benign but may invade local tissue and erode bone. The investigations required are radiological and histopathological examinations that further confirm the diagnosis. The differential diagnosis includes giant cell tumor and telangiectatic osteosarcoma. Here, we discuss a case of an aneurysmal bone cyst of the head of the fibula, which is a rare site for ABC to occur (common sites are metaphyseal ends of the femur, humerus, tibia, scapula, and vertebrae). The treatment modalities have a wide range of options that range from en bloc resection to minimally invasive techniques such as selective artery embolization, sclerotherapy, and radiotherapy.
