[Morphometric analysis of cervical pedicles in a Mexican population].

Background: Knowledge of the morphometric anatomy of cervical pedicles is essential for the safe and accurate placement of pedicle screws during instrumentation of the cervical spine. Screw placement in the lumbar and thoracic vertebrae is considered as a safe practice, unlike the cervical vertebrae due to the risks involved. There are few reports on this technique.

[Fracture dislocation of the thoracolumbar spine in pregnant patient: diagnostic by image and treatment].

Background: Fracture dislocations of the thoracolumbar spine are, to a great extent, associated with neurologic deficit and instability, so a large percentage of them require surgical treatment. Being pregnant does not rule out the possibility of having this type of lesions. There are only a few bibliographic references concerning these cases and medical and treatment ignorance about them is frequent.

[Neurologic changes in patients with traumatic cord lesion based in the analysis of the sequential clinical history].

Objective: To determine changes in neurological status in patients with traumatic cord lesions before and after surgical treatment.

Material And Methods: We conducted a descriptive cohort study, and measured 61 points of neurologic evaluation (sensory, motor, reflexes) of the Sequential Clinical History.

Results: We studied 28 patients with complete cord lesion (ASIA A) and 16 with incomplete cord lesions (9 ASIA B, 4 ASIA C, and 3 ASIA D).
