Case Reports
Kyphoscoliosis associated with congenital neuromuscular disease with uniform type 1 fibers.
To report the first case of surgical treatment for severe kyphoscoliosis associated with respiratory disorder in a patient with congenital neuromuscular disease with uniform type 1 fibers (CNMDU1), including management of the possible onset of malignant hyperthermia (MH) in general anesthesia. CNMDU1 is rare among congenital neuromuscular diseases, and surgery for spinal deformity in CNMDU1 has not been described. Onset of MH in general anesthesia is a concern in this disease. ⋯ Spinal deformity in CNMDU1 has a risk of severe progression, which makes early diagnosis by biopsy important. The surgery may be recommended before severe progression of spinal deformity and respiratory disorder. Perioperative MH is a concern, but can be managed by appropriate procedures.

To present a rare case of multiple compressive thoracic intradural cysts with pathologic arachnoid ossification, review the literature and present the surgical options. Few reports have identified the existence of arachnoid calcifications and intrathecal cysts causing progressive myelopathy. The literature regarding each of these pathologies is limited to case reports. Their clinical significance is not well studied, although known to cause neurologic sequelae. ⋯ On last examination, the patient's neurologic status had not improved, but had stabilized. The rate of neurologic improvement from excision and decompression is variable, but it may still be warranted in the face of progressive neurologic deficits.

With regard to the literature, several factors are considered to have an impact on postoperative mobility after lumbar total disc replacement (TDR). As TDR results in a distraction of the ligamentous structures, theoretically the postoperatively disc height and ligamentous integrity have also an influence on biomechanics of a treated segment. The purpose of the study was to evaluate the influence of posterior longitudinal ligament (PLL) resection and segmental distraction on range of motion (ROM). ⋯ But it still remains unclear if this increase which is in median not more than 1° may alter the clinical results. Moreover, the destabilizing effect of PLL resection can be reversed using a higher implant. The prosthesis height seems more crucial than PLL preservation to maintain the primary stability after TDR.

Case report and literature review. ⋯ Chordoma is a highly uncommon epidural neoplasm of the thoracic spine and is vanishingly rare in elderly patients. This report documents the oldest reported patient with thoracic spine chordoma at 89-year-old. Their locally aggressive behavior typically prompts consideration of aggressive surgical resection. When tailored to the individual patient, such procedures are feasible without excessive morbidity even in elderly patients.

Isolated intraspinal extradural tuberculous granuloma (IETG) without radiological evidence of vertebral involvement is uncommon, especially rare in cervical spine. ⋯ The isolated IETG, although a rare entity, should be considered in the differential diagnosis of the intraspinal mass, especially in patients with spinal cord compression and a history of tuberculosis. If there is a progressing neurological deficit, a combination of surgical and anti-tuberculous treatment should be the optimal choice.
