Neurological manifestations in spinal tuberculosis often occur secondary to vertebral involvement. However, tuberculoma of the spinal cord or extradural granuloma without radiological evidence of vertebral involvement may be responsible for neurological complications. We report 22 patients with intraspinal tuberculoma (19 extradural, three intramedullary) ranging in age from 17 to 70 years. ⋯ The other two patients were treated nonoperatively with antitubercular therapy and showed complete neural recovery. All patients received antitubercular therapy for a minimum of 1 year. Intraspinal tubercular granuloma should be considered in the differential diagnosis when a case of spinal tumor syndrome is encountered in an endemic zone of tuberculosis.

Computer navigation allows for accurate reduction of femoral fractures.
Femoral nailing for reduction and stabilization of femoral fractures is a common orthopaedic procedure. However, angular and rotational malalignment is not an infrequent result, and extensive use of fluoroscopy is commonly involved. We tested the accuracy of a computerized navigation system to enhance multiplanar fracture reduction and to decrease the requirement for fluoroscopy. ⋯ Rotational accuracy was 1.7 degrees +/- 1.9 degrees and 2.5 degrees +/- 1.8 degrees, respectively. Open reduction using this model yielded no difference between the reduced fracture and the intact bone in coronal and rotational alignment. Computerized navigation has the potential for increasing precision in fracture reduction while minimizing fluoroscopic requirements.
