Giant cell tumor (GCT) of the distal end of the ulna is an uncommon site for primary bone tumors. When it occurs, en-bloc resection of the distal part of the ulna with or without reconstruction stabilization of the ulnar stump is the recommended treatment. We present a case of a 56-year-old man with a GCT of the distal ulna treated successfully with an en-bloc resection of the distal ulna with reconstruction using radioulnar joint prosthesis. Although the experience with this type of treatment is limited, implantation of a metallic prosthesis to replace the distal part of the ulna can also be considered as a salvage procedure for the treatment of this difficult pathology.

According to our experience there are several presentations of FAI and associated hip conditions, where other authors advocate surgical dislocation, which can be conducted through a mini-open approach when increased surgical skills are reached. Moreover, this technique was found to be useful as an additional tool to consider, even for surgeons involved in the arthroscopic learning curve.

Many of the described labral-reconstruction procedures are purely arthroscopic. This approach only allows segmentary reconstructions. For more extensive reconstructions, surgical dislocation of the hip still represents the more suitable approach. We present an arthroscopy-assisted procedure combined with an anterior mini-open approach, which could be considered for reconstruction of nonrepairable labral lesions located in the posterior aspect of the acetabulum and massive reconstructions in cases of global-pincer femoroacetabular impingement and protrusio acetabuli. Our technique saves the morbidity that might be related to the surgical dislocation of the hip and incorporates a peroneus brevis tendon allograft. This option may restore the anatomy and labral function without morbidity at the donor site, as well as remove graft length restrictions during massive reconstructions.

In the previous decade, metal-on-metal hip resurfacing has been considered an attractive option and theoretically advantageous over conventional total hip arthroplasty, especially in young active patients. Different authors have reported favourable mid-term clinical and functional results with acceptable survival rates. Proper indication and planning, as accurate technical execution have been advocated to be crucial elements for success.Concerns regarding serum metal ion levels and possible clinical implications have led in the last years to a decline in the use of metal-on-metal hip resurfacing and metal-on-metal bearings in general.The aim of this study is to present the results of our first 486 cases of hybrid hip resurfacing arthroplasties with a second generation cementing technique, and to describe our current restricted indication of this type of prosthesis, in the light of recent findings in the literature about the possible complications related to metallosis or improper patient selection. Global survivorship of our series was 97.9% at a mean follow-up of 7.2 years.In the second season of our experience the indication is restrictive. The candidate for a resurfacing hip replacement is a young and active male patient, with good bone quality, that has been made aware of the risks and benefits of this type of prosthesis.

We concluded that labral reconstruction with tendon allograft provides relief of painful symptoms, and represents a reliable alternative for patients with nonrepairable labral tears that are not yet candidates for a joint replacement procedure.

Objetivos. Evaluamos nuestra experiencia con el tornillo canulado percutáneo mini-Acutrak en el tratamiento de las fracturas agudas de escafoides. Material y Método. Desde noviembre de 2007 a septiembre del 2008 realizamos un estudio retrospectivo en 22 pacientes con fractura de escafoides. El patrón de fractura se dividió según la clasificación de Herbert y por los criterios de inestabilidad propuestos por Cooney et al. No se incluyen las fracturas de cuerpo de escafoides inestables. Las fracturas mínimamente o no desplazadas de cuerpo de escafoides se trataron con un tornillo percutáneo vía palmar. En las fracturas de polo proximal y oblicuas de cuerpo se colocó el tornillo vía dorsal. Posterior a la osteosíntesis se realiza una inmovilización de 10 días y seguidamente fisioterapia. Resultados. De los 22 pacientes intervenidos uno fue una mujer y 21 fueron varones de edad media 27 años (rango: 18-47). El seguimiento medio fue de 6 meses (rango: 3-10). La osteosíntesis percutánea se indicó en 15 fracturas mínimamente o no desplazadas de cuerpo escafoides (Herbert tipo A2 o B2), 3 fracturas oblicuas (Herbert tipo B1) y 4 de polo proximal (Herbert tipo B3). Todos los pacientes obtuvieron resultados buenos/excelentes con un tiempo de curación entre las 8 y 12 semanas (media de 6 semanas) y con un arco de movilidad completo. La tomografía axial computerizada fue útil en 8 casos para confirmar la consolidación. La longitud media de los tornillos fue de 18 mm (rango: 16-22). Como complicación tuvimos un caso de ruptura de la aguja guía en el interior del tornillo. No hemos apreciado casos de seudoartrosis, inestabilidad, infección, aflojamiento del tornillo ni cambios degenerativos. Conclusiones. El tornillo de compresión percutáneo puede evitar el abordaje y los posibles daños de la osteosíntesis abierta. Si se realiza una indicación y vía de entrada correcta puede, en las fracturas agudas de escafoides mínimamente o no desplazadas, permitir la consolidación de la fractura con un tiempo de inmovilización menor y una incorporación precoz a las actividades habituales.
