Intraoperative radioactive localization of osteoid osteomas: four case reports.

We have excised four osteoid osteomas in four children, aided by intraoperative radioactive localization. Here we report these cases and describe the equipment used. Exact detection and elective excision are the two advantages of this technique.

[Advantages and disadvantages of peroperative isotopic localization in the excision of osteoid osteoma. Considerations apropos of 6 cases]. / Intérêts et pièges du repérage isotopique peropératoire dans l'exérèse de l'ostéome ostéoïde. Réflexions à propos de 6 observations.

We have excised six cases of osteoid osteoma in children, by using intra-operative accurate radioactive localization. The value of this technique is considerable and allows a better localization of the lesion. Exact detection and elective excision are the two advantages of this technique. We are reporting these case and describing the equipment being used.

[Daily rectal bleeding caused by venous angiodysplasia of the rectum]. / Rectorragies quotidiennes par angiodysplasie veineuse du rectum.

The authors report a case of venous angiodysplasia of the rectum in a child. This 5 years old boy presented rectal bleeding about each day. The treatment was abdomino-anal pull through resection of the rectum. The localisation of this malformation is quite exceptional in the literature.

[Complete fracture-dislocation of thoracic vertebrae 8 and 9 without neurological complications. Description of the injury. Therapeutic deductions]. / Fracture-luxation complète D8-D9 sans complications neurologiques Description lésionnelle - Déductions thérapeutiques.

The author has seen one case of complete fracture dislocation between the 8th and 9th thoracic vertebrae without paraplegia. An analysis of the lesion was made by tomodensitometry. It is concluded that the absence of a lesion of the spinal cord was due to an associated fracture of half of the posterior arch of the 8th thoracic vertebra. The treatment was based on conservative reduction and fixation by a halo cast. A review of the literature has shown only one similar case.
