Open Anterior Peri-lunarDislocation of the Carp: A Case Report.

Introduction: The anterior perilunate dislocations of the carp (PDC)are exceptional and poorly known lesions, which may go unnoticed in an emergency. They derive their importance from the severity of sequelae, which are dominated by chronic wrist instability and long-term osteoarthritis.

Case Report: We report the case of an open anterior PDC with no carpal fracture in a young patient.

A Rare Case of Tuberculosis with Sacrococcygeal Involvement Miming a Neoplasm.

Infection of the lumbosacral junction by tuberculosis is quite rare and occurs in only 1 to 2% of all cases of spinal tuberculosis; moreover, isolated sacrococcygeal or coccygeal tuberculosis is much rarer. Failure to identify and treat these areas of involvement at an early stage may lead to serious complications such as vertebral collapse, spinal compression, and spinal deformity. In the present paper, we report an uncommon case of spinal tuberculosis with sacrococcygeal location revealed by a chronic low back pain that was successfully managed.

[Chondroblastoma of bone ].

Background: Chondroblastoma is a rare and benign cartilaginous tumor of bone often localized in the epiphysis of long bones and affecting young persons between 10 and 20 years.

Aim: To study the epidemiological, clinical and radiological aspects of bone chondroblastoma, to assess the outcome of chirurgical treatment and factors associated with recurrence.

Methods: It's a retrospective study, concerning 13 patients with chondroblastoma of bone, attending the orthopedic department of Sahloul hospital between 1991 and 2007.
