[Isolated radiocarpal luxation. A case report and general review of the literature].

Purpose Of The Study: We describe a case of an isolated radiocarpal dislocation and review the literature.

Case Report: A young 29-year-old male, suffering from a wrist injury after a motor cycle accident, was diagnosed as dorsal radiocarpal joint dislocation with distal radioulnar dislocation and no fracture, close reduction was immediately performed followed by plaster cast immobilisation. After five months satisfactory stability and motion were obtained without signs of carpal instability.

[Modular construction (2 HS-1 SH), using Cotrel-Dubousset's universal instrumentation for comminuted fractures of the thoracolumbar junction. Comparison with various other constructions].

Introduction: The authors' objective was to study the anatomical and functional results of an original construct using the Cotrel-Dubousset instrumentation.

Material And Methods: This construct is called "Modular construct" or "2 H.S.

[Severe cervical spinal cord injuries without traumatic osteo-disco-ligamentous lesion].

The existence of cervical spinal cord injury without bony nor disco-ligamentous lesion rises pathogenic, prognostic and therapeutic challenges. The extent and localisation of cord injury, which depends on intensity and direction of the applied force, can explain the different clinical patterns: incomplete quadriplegia: 8 cases, incomplete Brown-Sequard-like quadriplegia: 2 cases, diplegia brachialis: 5 cases. We have not observed any complete quadriplegia.

[Vertebral hydatid cyst. Apropos of 2 cases].

The hydatid disease is rare in osseous locations, especially in our country (2.2 per cent). It has some particularities: clinical latency, diagnosis difficulties, surgical treatment often unsatisfactory because of the difficulty of total excision.
