Abstract

Since 1972, 18 patients suffering from metastatic cancer in the cervical spine were treated with prosthetic replacement surgery. The surgery enabled the authors to decompress the spinal cord and the nerve roots and at the same time restore stability in the affected spine. Patients suffering from severe pain and spinal cord and/or nerve root compression secondary to involvement of a single vertebral body particularly benefited from this surgery. The rates of positive recovery were as follows: 94.1% for pain relief, 91.7% for motor recovery, and 87.5% for ambulation. The surgical efficacy was maintained until the terminal stage. Tumor recurrence took place in five cases--two anterior, and three posterior. Anterior recurrence caused a marked instability, whereas posterior recurrence did not affect stability.

Surgical treatment of cervical kyphosis in Larsen syndrome: report of 3 cases and review of the literature.

STUDY DESIGN: A retrospective case series. OBJECTIVE: To review the surgical results for midcervical kyphosis in 3 cases with Larsen syndrome, and to discuss the choice of surgical treatments. SUMMARY OF BACKGROUND DATA: Cervical kyphosis is the most hazardous and serious manifestation of Larsen syndrome due to the risk of life-threatening paralysis, and thus usually requires surgical treatment. However, little information has been reported concerning surgical treatments for this challenging condition. METHODS: Three patients with Larsen syndrome were surgically treated for midcervical kyphosis at our institution. RESULTS: An infant with mild cervical kyphosis was successfully treated with posterior arthrodesis using a halo immobilization, and anterior vertebral growth with a mature posterior fusion mass resulted in spontaneous correction of the kyphosis. In the remaining 2 infants with myelopathic symptoms due to severe and structural kyphosis, anterior decompression and fusion via a lateral approach followed by posterior fusion with segmental spinal instrumentation and halo immobilization resulted in improved neurologic symptoms and solid fusion. CONCLUSIONS: Posterior spinal fusion is only indicated for patients with mild and flexible cervical kyphosis, and anterior decompression and circumferential arthrodesis is required for patients with severe kyphotic deformity, who usually develop myelopathic symptoms. Anterior surgery for such a small patient with severe kyphosis involves much higher risk of spinal cord injury during decompression maneuvers and difficulty in stabilization of the reconstructed cervical spine. Therefore, all patients with Larsen syndrome should be screened with radiographs at the first visit to detect cervical kyphosis early so that posterior alone fusion is possible.
