[Primary tumours and pseudotumors of the hand in adults. Epidemiological analysis of cases, management and evolution].

Introduction: Tumors in the hand are rare, and malignant tumors in the hand are peculiar; However, primary pseudotumoral lesions of the hand, such as ganglion, are very frequent. Most of the tumors found in the bone and soft tissue can be presented in the same way in the hand but their frequency and distribution is different. Despite the low incidence of benign and malignant tumors in the hand, these can be locally invasive or compromise the hand function.

[Strength and function of hand before and after release of carpal tunnel in patients with type 2 diabetes mellitus by open and endoscopic approach. Case-control study].

Background: Carpal tunnel syndrome (CTS) is the upper extremity neuropathy more frequent. Treatments led to the entrapment of the median nerve in the carpal tunnel are more complicated and the results less promising and unsatisfactory in diabetic patients. The objective of this study is to compare the results of strength and hand function in healthy patients against patients with diabetes mellitus type 2 (DM2) with a diagnosis of CTS before and after the open and endoscopic release of the carpal tunnel.

[Intercarpal fusion as a salvage procedure in Kienböck disease].

Material And Methods: Transversal retrospective study of 33 patients treated with different surgical techniques and evaluated with Quick-DASH scale, dynamometer and EVA.

[Wrist arthroscopy for fractures of the distal end of the radius].

Introduction: Fractures of the distal end of the radius are very frequent in the orthopedist's practice. The anatomical reduction of the articular surface and the extra-articular alignment of the radius are extremely important to minimize complications. The purpose of the study is to make an arthroscopic diagnosis of the lesions associated to the distal radius and assist in the reduction of the distal radius fracture.
