Distal biceps tendon rupture: diagnostic strength of ultrasonography and magnetic resonance. / Rotura del tendón distal del bíceps: potencia diagnóstica de la ecografía y la resonancia magnética.

OBJECTIVE: The main purpose of this study is to determine the agreement between two radiological tests, ultrasonography and magnetic resonance, in the diagnosis of distal brachial biceps tendon injury. MATERIAL AND METHOD: A retrospective study was made of patients over 3 years who underwent distal brachial biceps tendon reattachment open surgery, and whose preoperative diagnosis was complemented either by ultrasonography, by magnetic resonance or both. The agreement was calculated by Cohen's kappa coefficient (k). RESULTS: Information of 79 patients was analyzed. The concordance was excellent between resonance and surgical findings (k=.950), and a good Cohen's kappa coefficient was also achieved between both ultrasonography and surgery (k=.706) and between information of sonography and magnetic resonance (k=.667). CONCLUSIONS: Resonance and ultrasonography could be considered reliable diagnostic tests to determine the acute rupture of the distal brachial biceps tendon in patients with consistent aetiology and physical examination.

Protocolo de tratamiento funcional en el esguince agudo no grave de tobillo. Alta laboral precoz / Functional treatment protocol for acute mild-moderate ankle sprain. Early return to work

Se presentan los resultados obtenidos con tratamiento funcional en los esguinces no graves de tobillo, según protocolo propio. Para ello se revisan de forma retrospectiva 72 pacientes tratados en el año 1999 por presentar esguince agudo lateral externo de tobillo grado II. La curación y vuelta a la actividad previa se obtuvo en el 100 per cent de los casos. Recibieron el alta laboral tras 7,6 días de media (2-21). Sólo tres pacientes presentaron dolor residual que cedió antes de los seis meses (AU)

Osteoma osteoide de cuello femoral: una causa infrecuente de dolor de cadera en niños / Osteoid osteoma in the femoral neck: a rare cause of hip pain in children

El dolor de cadera en el niño es uno de los motivos más frecuentes de consulta. Uno de los diagnósticos que deben ser considerados es el osteoma osteoide. Este es un tumor óseo benigno de características clínicas y radiológicas específicas que genera dificultades diagnósticas. Presentamos dos casos clínicos infrecuentes de osteoma osteoide de cadera en el niño y se revisa la bibliografía sobre el tema (AU)

Nonunion of the patella as a late chance observation after reconstructive surgery of the anterior cruciate ligament.

The use of autologous bone-tendon-bone grafts for reconstructive surgery of the anterior cruciate tendon is a widely diffused technique. Fracture of the donor patella constitutes an uncommon complication. It is the purpose of this study to present the clinical case of a patient submitted to reconstructive surgery of the anterior cruciate ligament where the existence of asymptomatic nonunion of the patella was by chance observed.
