Mechanical instability after acute ankle ligament injury: randomized prospective comparison of two forms of conservative treatment.

Objective: This trial has the objective to investigate the incidence of mechanical ankle instability after the conservative treatment of first episode, severe ankle ligamentar lesions. This common lesion affects young, professional and physical active patients, causing important personal and economic consequences. There are difficulties related to adequate diagnosis and treatment for these lesions.

CUBOID-NAVICULAR TARSAL COALITION.

The authors present the case of a nine-year-old female patient who presented with pain in her right foot associated with physical activities. After this case was diagnosed as cuboid-navicular tarsal coalition, the patient was treated surgically with resection of the coalition, thereby resolving the symptoms. The literature was reviewed and the importance of adequate physical examination and imaging assessment for investigating foot pain in children and adolescents was discussed.

Benign bone tumors subperiosteal on the talar neck resected anthroscopically: case reports.

Two cases of benign chondral tumors of the talar neck region (an osteoid osteoma and a chondroblastoma) were described. Because of their specific, unusual site they could be resected by arthroscopy. The imaging aspects, incidence in foot bones and possibilities of treatment were discussed, and a literature review is presented.

Anatomic study of the filum terminale and its correlations with the tethered cord syndrome.

Objective: To evaluate the intradural anatomic features of the filum terminale (FT) in fresh human cadavers, analyzing morphological parameters relevant for the diagnosis of the tethered cord syndrome.

Methods: Forty-one fresh cadavers were dissected, and the following parameters were evaluated: cadaver height, weight, and age, FT length, FT diameters at the initial point and midpoint, and topographic relationships of the initial and fusion points of the FT to the adjacent vertebrae.

Results: The mean FT length was 156.
