Abstract

A halo-body system is described which has been developed at Princess Margaret Rose Orthopaedic Hospital in Edinburgh. The system is easy to apply and consists of a standard halo, linked to malleable plates by two hollow vertical rods. These rods are connected to the ring by swivel joints which allow for the movements of flexion and extension. The malleable plates are incorporated into the plaster jacket which rests upon the iliac crests. The results of 13 patients who have had this system applied are discussed and include patients who have sustained fractures of the cervical spine or who have had bone destruction from metastatic disease or from infection. Using this type of system there have been few complications and the patients have benefitted from easy mobilisation.

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.
