Combined closed avulsion of the central slip and terminal tendon of the finger extensor mechanism.

This clinical case describes a patient who suffered a combined closed avulsion of the central slip and the terminal tendon of the index finger extensor mechanism, associated with a unicondylar fracture of the middle phalanx and a spiroid fracture of the second metacarpal.

[Palmar scaphoid dislocation associated with dorsal perilunate dislocation. A case report and review of the literature]. / Luxación palmar del escafoides carpiano asociado a una luxación perilunar dorsal. A propósito de un caso y revisión de la bibliografía.

Most carpal dislocations occur in the lunate bone or around it (perilunate). An isolated dislocation of the carpal scaphoid is a rare injury. We report a case of a palmar scaphoid dislocation combined with a dorsal perilunate dislocation, which was treated with open reduction, fixed with two Kirschner wires and ligament repair, with a good result.

[Unilateral congenital absence of the carpal scaphoid associated with dysplasia of the capitate. Presentation of a case]. / Ausencia congénita unilateral del escafoides carpiano y displasia del hueso grande. A propósito de un caso.

We report on a case of aplasia or unilateral congenital absence of the carpal scaphoid associated with dysplasia of the capitate. Congenital absence of the carpal scaphoid is a rare but well-documented condition. As far as we know, the present case is the seventh one reported in the medical literature. Imaging studies (X-ray and MRI) confirmed the absence of the carpal scaphoid associated with a dysplasia of the capitate and malformation of the radial styloid process. Congenital absence of the scaphoid when other congenital abnormalities (such as hypoplasia or aplasia of either forearm bones or thenar eminence, malformations of the skeletal elements of the thumb, absence of sesamoid bones or abnormal development of the forearm bones) do not exist is probably the main feature of the present case report.

[Giant enchondroma of the thumb distal phalanx. Presentation of a case and review of the literature]. / Encondroma gigante falange distal del pulgar. A propósito de un caso y revisión de la bibliografía.

We report on a case of giant enchondroma of the distal phalanx of the thumb, with a significant degree of clinical and radiographic deformity. It is extremely rare in this location and its treatment should be surgical, with curettage of the lesional cavity and filling with autologous bone graft. In this case, we performed a differential diagnosis of a giant cell tumour and aneurysmatic bone cyst (X-ray and nuclear magnetic resonance [NMR]).
