[Giant cell tumours in a pyramidal bone: a clinical case and a review of the literature].

Giant cell tumours (GCT) of the bone are benign, but locally invasive tumours. We present a new case of carpus GCT, involving the triquetrum. The diagnosis required a prior biopsy before doing the block resection.

Complete medial dislocation of the first cuneiform: a case report.

Isolated dislocation of the first cuneiform bone is an extremely rare lesion that can usually be diagnosed on plain radiography. Few cases of this injury have been previously described in the literature. The case presented here resulted from a torsion injury and was treated by means of closed reduction with the aid of pointed reduction forceps.

Intradural disc herniation and epidural gas: something more than a casual association?

Study Design: The case of a patient with an intradural disc herniation associated with gas in the spinal canal is presented.

Objective: To alert spine surgeons to this potential association.

Summary Of Background Data: This association was described previously in five patients, a fact that seems surprising given the relative rarity of both intraspinal gas and intradural herniations.

L5 root compression resulting from an L2-L3 disc herniation.

We present the rare case of a patient affected by low back pain and bilateral L5 sciatica from an L2-L3 herniation. Only 2 cases of monoradicular L5 compression in the high lumbar spine have been reported. The initial computed tomography study of the L4-L5 and L5-S1 spaces revealed no significant alterations.

Posterior sternoclavicular dislocation. Report of two cases.

Posterior sternoclavicular dislocation is a relatively uncommon lesion, but must always be considered in the event of trauma to the scapulothoracic area in which initial radiology does not show signs of fracture. Its diagnosis and treatment must be carried out promptly because of the possible serious complications that may occur through the clavicle compressing nearby structures. The authors report two cases, which were diagnosed by CT-scan.

Chronic exertional compartment syndrome of the legs in adolescents.

We present our experience in the management and treatment of chronic exertional compartment syndrome (CECS) of the legs in 23 adolescents. Twenty-one patients were affected in the anteroexternal compartment, one in the deep posterior compartment, and one in both. Seventeen of the patients were in-line competitive skaters; the rest practiced soccer or athletics.

Fibrous dysplasia of both alae of the sacrum.

A case of monostotic fibrous dysplasia involving both alae of the sacrum is reported. Only 2 cases of monostotic sacral involvement were published previously. The lesion was detected in a 42-year-old man suffering from lumbosacral pain after minimal trauma.

Legg-Calvé-Perthes disease and passive smoking.

We carried out a case-control study with 90 patients with Legg-Calvé-Perthes disease (LCPD) and 183 normal children, as controls, selected at random to determine whether the condition of passive smoking is related to the disease. Seventy-one of 90 of the LCPD group (78.9%) were passive smokers.

Transverse stress fracture of the patella in a child.

Transverse stress fracture of the patella in a child is an exceptional injury in childhood. Only one case has been previously reported. The present study reports a new case of a 12-year-old boy with anterior knee pain misdiagnosed for 5 months as Sinding-Larsen-Johansson disease who developed sudden anterior right knee pain and pop while running in a soccer match.
