[Predictive criterions of unrecognized articular effraction after internal fixation of femoral neck fractures].

On the basis of a retrospective study comprising 91 cases of femoral neck fracture treated by DHS, unrecognized screw articular penetration was observed in 9 cases (9.9%). The coxa valga (Garden I) fractures are the most interested by this complication (7 cases out of 9).

Concomitant alar and apical ligament avulsion in atlanto-axial rotatory fixation. Case report and review of the literature.

The authors report a case of Fielding type II acute atlanto-axial rotatory fixation (AARF). The CT scan with coronal reconstruction showed an avulsion of the apical and right alar ligament. These findings are exceptionally reported in the literature, especially concerning the apical ligament which might be a stabiliser in flexion and extension of the occipitocervical joint.

Radical cure of vertebral hydatidosis. A case report.

The authors present a rare case of univertebral hydatidosis, and report encouraging results 12 years after radical resection of the involved vertebra. They stress the importance of computed tomography and especially magnetic resonance for monitoring early recurrence. A two-staged anterior and posterior approach, although difficult, seems to offer a very good prognosis in case of univertebral localisation.
