Outcomes of surgical treatments of spinal metastases: a prospective study.

Background: Owing to recent advances in cancer therapy, updated data are required for clinicians counselling patients on treatment of spinal metastases.

Objective: To analyse the outcomes of surgical treatments of spinal metastases.

Methods: Prospective and multicentric study that included consecutively patients operated on for spinal metastases between January 2016 and January 2017.

[Shortening arthrodesis of three wrist bones].

In advanced cases of wrist osteoarthritis with lesions of the radio-scaphoid and mediocarpal joints, and when a proximal row carpectomy is not possible because of lesions of the head of the capitate, we suggest a new technique: The hamate-capitate-lunate shortening arthrodesis with a scaphoid-triquetral resection. The good results observed with proximal row carpectomies, and particularly their long-term reliability, have encouraged us on this new path. Effectively, this operation takes the concept of proximal row carpectomy one step further by reconstructing the head of the capitate with the lunate whose proximal articular surface is often not deteriorated even in very advanced cases of radio and mediocarpal osteoarthritis.

Asymptomatic cervical haemangioma treated by percutaneous vertebroplasty.

We report a 17-year-old asymptomatic patient with a partially collapsed seventh cervical vertebra due to a haemangioma revealed by conventional radiographs performed for army enrollment. Given radiological evidence of aggressiveness, percutaneous vertebroplasty by injection of methyl methacrylate cement was performed to prevent complications. CT a year later showed no progression of the lesion.

Thoracic spinal trauma and associated injuries: should early spinal decompression be considered?

The relative benefits of conservative or surgical treatment in thoracic spinal trauma are still controversial. Owing to its anatomic relations, thoracic spinal trauma is specific regarding neurologic prognosis, the high incidence of associated injuries, and surgical management. Over a 30-month period, 49 patients sustained thoracic spinal trauma with neurologic impairment.

Blount's disease: magnetic resonance imaging.

To evaluate the information obtained by magnetic resonance (MR) imaging, the radiographic and MR investigations of nine patients treated for idiopathic tibia vara were reviewed in retrospect. There were six unilateral and three bilateral cases (12 tibiae). Initial radiographs of each patient were assigned a stage according to Catonné's classification.

Traumatic spondylolisthesis of the axis associated with a spinal cord rupture in T1.

Traumatic spondylolisthesis of the axis is rarely associated with neurological deficit. The authors describe a case of complete tetraplegia due to spinal cord rupture at T1 without any other osteoligamentous lesion at the level. The mechanism of this lesion is discussed; it seems to be due to hyperflexion, with preceding hyperextension responsible for the C2 pedicular fracture.
