Lateral hinge fracture in medial opening wedge high tibial osteotomy: a narrative review.

Lateral hinge fractures (LHF) are one of the most common complications of medial opening wedge high tibial osteotomy (MOWHTO), and are the leading cause of construct instability displacement, non-union, and varus recurrence after this procedure. To date, Takeuchi's classification is the most popular classification to describe this complication, and it can help surgeons to make intra and postoperative decisions. Opening medial gap width is the most recognized factor related to LHF occurrence.

Posteromedial Submeniscal Arthrotomy and Fixation with a Posteromedial Rim Plate in a Comminuted Medial Tibial Plateau Fracture.

Medial tibial plateau fractures generally present as simple metaphyseal fractures; however, certain cases may present as comminuted articular fractures. Medial and posteromedial anatomical plates have traditionally been used for their management; nevertheless, not all cases can be successfully managed using these implants. We present a comminuted posteromedial Schatzker type VI tibial plateau fracture case.

Dynamic-Anatomical Reconstruction of Medial Patellofemoral Ligament in Open Physis.

Patellar dislocation is a common knee problem, 10 times more frequent in childhood and adolescence. Medial patellofemoral ligament is injured up to 94% of the time, and its reconstruction is effective in terms of stabilization of the patella. However, distal femoral physis can be damaged with different techniques of reconstruction, due to the location of the femoral footprint.

[Parvovirus B19 among blood donors from three hospitals in Santiago, Chile].

Background: Parvovirus B19 (B19) is associated with a wide range of diseases in humans, whose severity depends on the immunological and hematological status of the host. It is transmitted mainly through the airway but also by transfusions.

Aim: To determine the B19 DNA carrier frequency in a population of volunteer blood donors from three hospitals blood banks in Santiago, Chile, and to determine the viral load in DNA positive cases.

[Seroprevalence of IgG antibodies against parvovirus B19 among blood donors from Santiago, Chile].

Background: Parvovirus B19 (B19) is associated with a wide range of disease manifestations, whose severity depends on the immunological and hematological status of the host. Infection with B19 has been reported worldwide and the prevalence of immunoglobulin G antibodies against B19 increases with age and varies by location and time of the last B19 epidemic.

Aim: To evaluate the prevalence of IgG antibodies against Parvavirus B19 virus in a population of volunteer blood donors at two hospital blood banks in Santiago, Chile.
