There are two main categories of surgical management for lateral TMT joints arthritis: fusion and motion preserving surgeries, which include resection arthroplasty, tendon interpositional arthroplasty ceramic arthroplasty. This article reports the first case interposition 5th joint with Dx Reinforcement Matrix®, a porcine dermal extracellular matrix.We present 22-year-old male who suffered moto...

Given a set of rectangular items, all of them associated with a profit, and a single bigger rectangular bin, we can ask to find a non-rotational, non-overlapping packing of a selection of these items into the bin to maximize the profit. A detailed description of the (2 + )-approximation algorithm of Jansen and Zhang [8] for the twodimensional case is given. Furthermore we derive a (16 + )-appro...

A case is presented of isolated scaphoid dislocation with carpal dissociation in the presence of a lunato-triquetral coalition. We present the treatment and follow-up of this case. In addition, the literature on scaphoid dislocation and its treatment is reviewed. We emphasize the need to reconstruct the carpal alignment and scapho-lunate linkage.

A rare case of an isolated traumatic palmar dislocation of the distal radioulnar joint is presented. Clinically, there is a loss of pronation and supination. The dislocation was treated using an open reduction, reinsertion of the capsule-ligamentous complex and temporary stabilization using K-wires.
