[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.

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

La mayoría de las luxaciones del carpo ocurren en el semilunar o a su alrededor (perilunar). La luxación aislada del escafoides carpiano es una entidad rara. Presentamos un caso clínico de luxación palmar del escafoides asociada con una luxación perilunar dorsal, tratado con reducción abierta, y estabilizado con 2 agujas de Kirschner y reparación ligamentosa, con buen resultado (AU)

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

Presentamos un caso de aplasia o ausencia congénita unilateral del escafoides carpiano asociado a displasia del hueso grande. La ausencia congénita del escafoides carpiano es una entidad rara e infrecuente, pero bien documentada. Es el séptimo caso presentado en la literatura. A diferencia de la mayoría de los casos publicados de aplasia/hipoplasia de escafoides carpiano, en nuestro caso no se ha detectado asociación de otras anomalías congénitas tipo hipoplasia o aplasia de musculatura tenar y antebrazo, malformaciones del esqueleto del pulgar, ausencia de huesos sesamoideos o alteraciones del desarrollo de los huesos del antebrazo. El estudio radiológico revela la ausencia congénita del escafoides asociado a una displasia del hueso grande e hipoplasia de la estiloides radial. Se completa el estudio con resonancia magnética nuclear (AU)

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 (AU)

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

Presentamos un caso de encondroma gigante de la falange distal del pulgar, con importante deformidad clínica y radiológica, extremadamente infrecuente en dicha localización y cuyo tratamiento es quirúrgico mediante curetaje de la cavidad lesional y relleno con autoinjerto óseo. En este caso realizamos diagnóstico diferencial con tumor de células gigantes y quiste óseo aneurismático (radiológico y resonancia magnética nuclear) (AU)

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]) (AU)

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.

[Irreducible physeal fracture of the distal radius due to entrapment of the extensor pollicis longus. A case report]. / Fractura fisaria de radio distal irreducible por atrapamiento del extensor pollicis longus. Reporte de un caso.

We present a clinical case of entrapment of the extensor pollicis longus at the level of the fracture site in a distal radius epiphysiolysthesis. The active mobility deficit of the patient's thumb, pain upon passive mobility, and the X-rays should make us suspect this lesion.

Arrancamiento del flexor profundo a través de un encodroma: a propósito de un caso y revisión de la bibliografía / Avulsion of the deep flexor muscle enchondroma through an enchondroma: presentation of a case and review of the literature

Se presenta un caso clínico donde coexis en un arrancamiento del flexor profundo del dedo meñique con un encondroma en la base de la tercera falange. Se trata de una combinación poco frecuente; se expone el tratamiento realizado y se revisa la bibliografía existente (AU)

We report a case with coexistence of an avulsion of the deep flexor muscle of the 5th finger with an enchodroma at the base of the third phalanx. This is a rare combination; we describe the treatment given and review the literature (AU)

Sección completa del ciático poplíteo externo durante una meniscectomía externa por artroscopia / Complete section of the external popliteal sciatic nerve during arthroscopic lateral meniscectomy

Objetivo: Comunicar la lesión del nervio ciático poplíteo externo (CPE) como complicación inusual tras una artroscopia de rodilla. Caso clínico: Presentamos el caso clínico de un paciente que presenta una sección completa del nervio CPE, tras una meniscectomía externa por artroscopia, que precisó la realización de injerto nervioso para conseguir la recuperación. Discusión: Las lesiones neurológicas tras la artroscopia de rodilla son infrecuentes, no hemos encontrado un caso de sección completa con pérdida de continuidad neurológica tras una meniscectomía y existen casos publicados similares que son comentados. Conclusiones: Aunque infrecuente, es posible la lesión de estructuras nerviosas durante la práctica de una artroscopia de rodilla (AU)

Purpose: The aim of this paper is to present a case of external popliteal sciatic nerve injury, which is an unusual complication following knee arthroscopy. Clinical case: We present the case of a patient who suffered a complete rupture of the external popliteal sciatic nerve (EPSN), following arthroscopic lateral meniscectomy, which required the use of a nerve graft to facilitate recovery. Discussion: Nerve lesions following knee arthroscopy are rare. We have found no instances of complete nerve rupture accompanied by a break in neurologic continuity following meniscectomy. We have however found a few similar cases, which we report on in the paper. Conclusions: Although uncommon, injury to nerve structures is possible during knee arthroscopy (AU)

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.

[Metastasis of an adenocarcinoma of the colon to the 1st metacarpal bone]. / Métastases d'un adénocarcinome du côlon au premier métacarpien.

The authors report a clinical case of metastasis to the first metacarpal arising from carcinoma of the colon, treated surgically four years previously. Clinical examination revealed painful swelling over the right thenar eminence. The diagnosis was established by radiology and needle biopsy. No treatment was administered and the patient died one month later. Metastases of the hand are uncommon and, according to the review of the international literature concerning bone metastases in the hand conducted by Kerin (1987), are usually secondary to lung, renal and breast cancers. Only a few cases have been described in the literature of bone metastases of the hand from carcinoma of the colon. The authors feel that some of these cases probably remain undiagnosed, as they are of secondary importance in view to the severity of the disease.
