OBJECTIVE The purpose of this study was to evaluate the effectiveness of demineralized bone matrix (DBM) with and without platelet-rich plasma (PRP) in the treatment of osteochondral defects (OCDs) of the talus. We hypothesized that treatment with DBM would result in more bone formation than no treatment in control OCDs, and that PRP would further enhance the regenerative capacity of DBM. MET...

INTRODUCTION Subtalar dislocation is an uncommon lesion in traumatology chiefly when it concerns the lateral form. Surgical treatment is required when a fracture is related or the dislocation is irreducible. Even well treated, these dislocations progress unavoidably to subtalar arthrosis, which stays well tolerated. CASE REPORT A 46-year-old male with irreducible lateral subtalar dislocation ...

Due to the very unique disposition of the articular surfaces associated with the talus, the bone and its constituent components (body and the head) are oriented in specialised spatial orientation. Thus, the force subjected to the talus in load bearing not only dictates the resultant shapes and dimensions of the articular surfaces acquired by the bone, stress on the talus also probably decides t...

Determinantal point processes (DPPs) provide a probabilistic formalism for modeling repulsive distributions over subsets. Such priors encourage diversity between selected items through the introduction of a kernel matrix that determines which items are similar and therefore less likely to appear together. We investigate the usefulness of such priors in the context of spike-and-slab variable sel...

Vogliamo subito precisare che il problema di dimostrare la primalità di un intero è cosa diversa da quella di ricercarne gli eventuali fattori. Infatti esistono dei risultati che garantiscono la primalità di un numero mediante opportune condizioni equivalenti; il fatto che tali condizioni risultino non verificate consente quindi di concludere che tale numero è composto senza doverne esibire un ...
