[Retrocaval ureter in a 10-year-old boy].

Retrocaval ureter is an uncommon abnormality of the inferior vena cava, which is rarely detected in the child due to its non-specific symptomatology. Despite a varying state of severity, chronic ureteral obstruction generally leads to the deterioration of renal function during adulthood. Treatment depends on the symptomatology in question, and surgical management should be as conservative as possible.

[Traumatic luxation of the posterior tibialis tendon].

Anterior dislocation of the tibialis posterior tendon is a traumatic lesion, which is rarely suspected following ankle trauma. It seems to be promoted by hypoplasia of the retromalleolar sulcus. Surgical treatment is easy and reportedly gives excellent results, but the diagnosis is difficult and absence of diagnosis may result in functional instability of the foot requiring more invasive surgical treatment.
