An unusual cause of locking of the knee is reported, due to an osteochondroma at or around the inner part of the upper tibia. It usually presents in young teenagers who frequently have difficulty extending the knee from a fully flexed position. The cause is interference with the free excursion of the pes anserinus. Excision of a symptomatic osteochondroma has been known to relieve the complaint.

Five cases of hydatid disease affecting the vertebrae are described. Clinical features, radiologic appearance, and poor prognosis are emphasized. Four patients had some degree of neurologic deficit at the time of presentation and in three cases there was an increasing kyphosis. In two patients, spinal instrumentation with Harrington apparatus supplemented removal of hydatid material, and its use improved the previous neurologic deficit with stabilization of kyphosis. The antihelmintic drug mebendazole was used in two cases.
