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)

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)
