Intraosseous Neurilemmoma of the First Lumbar Vertebra: A Case Report / 대한정형외과학회잡지

Intraosseous neurogenic tumors are rare and have been reported most commonly in the mandible, possibly because of the long course of the mental nerve within this bone. They have also been reported very rarely in a vertebra. We experienced a case of intraosseous neurilemmoma arising from the body of the first lumbar vertebra, which resulted in paraplegia. The tumor was removed completely through anterior and posterior approaches by staged operation. Postoperative course was uneventful and paraplegia was recovered within three months postoperatively.

Extension Contracture of Both Hip Joints Secondary to Congenital Fibrous Bands of Both Gluteus Maximus Muscles: Case Report / 대한정형외과학회잡지

Congenital fibrous bands may be found at the gluteus maximus, the gluteus medius,thequadriceqs,the triceps and the deltoideus muscles. Congenital fibrous bands of both gluteus maximus muscles are rare and cause extension contracture of the hip joints. We experienced a case of congenital fibrous bands of both gluteus maximus muscles associated with severe limited flexion of both hips. Almost full flexion of both hips was obtained by excision of the congenital fibrous bands.
