[Extension tear-drop fracture of the axis: a surgically treated case].
Tear-drop fracture of the axis is an exceptional spinal fracture which generally occurs after high-energy trauma with hyper-extension of the cervical spine. Purely anterior fracture can occur with no real impact on stability. Orthopedic treatment provides good results in this situation. If the fracture is posterior, it continues into the C2-C3 intervertebral disc and the common posterior vertebral ligament, leading to C2C3 instability and possible retrolisthesis of C2 over C3 and neurological involvement. We report a case of tear-drop fracture of C2 with C3 instability without neurological involvement. This patient underwent posterior fixation with C2C3 arthrodesis which provided good quality bone fusion without secondary displacement or clinical aggravation.
[Synovial cyst of the intercondylar fossa of the knee: three symptomatic cases and a review of the literature].
Synovial cyst of the intercondylar fossa of the knee or cyst of the "cruciate tentorium" is an uncommon finding. Most of the reports in the literature were made after the advent of magnetic resonance imaging. Most cysts are asymptomatic and discovered fortuitously. We report our experience with three cases of symptomatic cysts, describing the diagnostic and therapeutic approaches used. Clinical manifestations of symptomatic cysts are variable and non-specific. Pain is commonly observed with limitation of knee amplitudes. If their is no other suspected meniscal or osteochondral disease after clinical and MRI assessment, surgical treatment is only indicated in case of functional impairment. Medical care may be sufficient in certain cases, associating puncture and infiltration. In others surgical treatment, generally via an arthroscopic approach, is needed.
