Management of unicondylar femoral fractures is mainly done by open reduction and internal fixation. Anatomic reduction in the articular surface is paramount in this type of lesion. Medial condyle fractures lack specific osteosynthesis material for fixation.We report a case resolved with the sparsely documented technique using calcaneal plate fixation.

ResumoUma paciente de meia-idade com fratura do platô tibial e avulsão da eminência tibial foi tratada com uma combinação de fixação do platô com placa medial e sutura da eminência com fio não absorvível auxiliada por artroscopia.Nossa técnica para fraturas com avulsão da eminência tibial não interfere nos materiais de osteossíntese do platô tibial e, mais uma vez, teve bons resultados no tratamento de lesões combinadas e complexas do joelho.

Variations of Monteggia fractures are uncommon in the pediatric population and demand a high suspicion for early recognition and treatment. The involvement of the radial head in these types of injury isn’t well documented, but literary reports are growing. We report a case of a poorly documented variant of a Monteggia Equivalent Fracture with a Salter-Harris II fracture of the radial head with medial displacement and propose a new approach to the Bado classification in the pediatric population based on a literature review.

First described in 1957 by Dr Geoffrey Osborne, the Osborne ligament is defined as a band of tissue that connects the two heads of the flexor carpi ulnaris, which forms the roof of the cubital tunnel, between the medial epicondyle and the olecranon. We retrieved data from 16 elbows of 8 cadavers, measuring the length of the Osborne’s ligament in both maximum extension and in 90º flexion. Using this data, we managed to compare the differences between the left and right arm and also between male and female specimens. Our goal was to find statistically significant differences between the variables: males vs females; right vs left elbow; flexion vs extension. To our knowledge, no prior study has compared the length of this ligament between both elbows.

A transient wave propagation model is provided as a consequence of a new theory of porous media and wave propagation in saturated poroelastic media. This theory, in the linear case, becomes to be equivalent to the theory proposed by de Boer, R., Ehlers, W. & Liu, Z. in 1993. It leads to a model for the 1-D porous saturated column problem, which after the appropriate establishment of boundary and initial conditions, can be solved analytically with the aid of the Laplace transform concerning time. Numerical experiments are performed to illustrate the behavior of constituents displacement fields. The theory results in having an inertial effect on the motion of solid constituents as commonly expected. However, in contrast to Biot’s theory, is not introduced by the present theory the relative acceleration as an interactive force between solid and fluid constituents to account for the apparent inertial effect.
