[Magnetic resonance imaging of medial meniscus tears with displaced fragment in the meniscal recesses].

Purpose Of The Study: Displaced meniscus tears generally result from bucket handle tears with subsequent migration of the meniscal fragment into the intercondylar notch. More rarely, the fragment may move into the meniscal recesses. In this situation, the displaced fragment may be difficult to individualize arthroscopically, so preoperative imaging is crucial.

Spinal fracture through the neurocentral synchondrosis in battered children: a report of three cases.

Study Design: Retrospective case series.

Objective: To report 3 cases of unusual spinal fracture through the neurocentral synchondrosis.

Summary Of Background Data: Traumatic lesions of the spine or spinal cord due to physical abuse are rare.

Brown tumor of the spine and progressive paraplegia in a hemodialysis patient.

Study Design: Case report.

Objective: To describe the radiographic features and management of spinal brown tumor and to document tumor mineralization after parathyroidectomy.

Summary Of Background Data: Brown tumors are classic skeletal manifestations of hyperparathyroidism usually seen in severe forms.

[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.
