Clinical and electromyographic studies in the tarsal tunnel syndrome may suggest compression of only one of the two terminal branches of the posterior tibial nerve. This anatomical study demonstrates the structures which may cause isolated damage to either the medial plantar or the lateral plantar nerves. A surgical approach to the tarsal tunnel is described.

This is the report of a case with recurring giant cell tumor of the femur, which showed roentgenological evidence of pulmonary metastases. Only at the third biopsy sarcomatous changes as morphological signs of malignancy were found. Contrary to some elsewhere published giant cell tumors with sarcomatous components, there was no preceding irradiation in our case.

A case of "adamantinoma" of the tibia is reported. 10 years ago a giant tumor with fibrous dysplasia had been diagnosed in a biopsy taken from the same site of cystic bone changes. These findings may occur as reaction in the periphery of "adamantinomas" of long bones. By this experience the importance was emphasized, to obtain tissue from the center portion of the tumor to include the typical epithelial islets pathognomonic for "adamantinomas", which in our case, were found only 10 years after the first operation. Our patient was treated by curetting and filling of the defect with bony splinters. At this time, 8 months after surgery, he is without complaints and in full use of his diseased leg.
