Alkaptonuric arthropathy with periprosthetic fracture:a case report.

Alkaptonuria or Ochronosis is an autosomal recessive congenital metabolic error due to absence of enzyme homogentisic acid oxidase. Recently, we had an opportunity to diagnose this condition in one of our patients. An old aged man developed a pathological fracture of femur after a trivial fall at home.

Management of unstable thoracolumbar spinal fractures by pedicle screws and rods fixation.

Background: The thoracolumbar junction is the most common area of injury to the axial skeleton. Forces along the long stiff kyphotic thoracic spine switch abruptly into the mobile lordotic lumbar spine at the thoracolumbar junction. Goals of treatment are to obtain a painless, balanced, stable spine with optimum neurological function and maximum spine mobility.
