Compression of the radial nerve at the elbow is quite rare; entrapment of its superficial branch is exceptional. Extrinsic compression is the most frequent etiology. Magnetic resonance imaging plays a major role in the diagnosis, and early surgical excision or echoguided drainage - in case of synovial ganglion - allows a total recovery. The authors report the case of a compression of the superficial branch of radial nerve by an elbow synovial cyst treated by surgical resection., (Copyright © 2013 Elsevier Masson SAS.

Giant cell tumors (GCT) are locally aggressive tumors with a preference for epiphyses and metaphyses of long bones. They represent 5%-10% of all primary bone tumors. They affect mostly young adults between 20 and 40. Their origin remains uncertain. GCT is a purely lytic tumor, recurrent and can even lead to fracture. The distal radius is the third location after the distal femur and proximal tibia. Tumors are benign on histopathology, but "benign" lung metastases can sometimes be seen. Their treatment remains controversial because of the high rate of recurrence; oncological resection of the diseased bone segment with reconstruction reduces the rate of recurrence. Several techniques of resection and reconstruction of the wrist have been proposed. We report a case of giant cell tumor of the distal radius treated by resection and reconstruction by avascular fibular graft to a length of 12cm, and we evaluate the use of this reconstruction to salvage the wrist with this pathology., (Copyright © 2011 Elsevier Masson SAS.

Myositis ossificans circumscripta is a benign lesion characterized by focal heterotopic soft tissue ossification and occurring in young people generally after localized trauma. The location of this case in the forearm is rare. The clinical signs, radiological appearance and the histological features can be confused with osseous or soft tissue sarcoma, as was the case in our patient.

Elastofibroma dorsi is a slowly-growing benign tumor which usually occurs at the inferior angle of the scapula. It may be more of a degenerative process than a neoplasia. We seek, through our observations and a review of the literature, to clarify the characteristics of this tumor and its modes of management. We think that all doctors should be aware of this condition, in order to treat it correctly.
