Case Reports
Spontaneous spinal epidural haematoma during Factor Xa inhibitor treatment (Rivaroxaban).
We report on a 61-year-old female patient who developed a spontaneous spinal epidural haematoma (SSEH) after being treated by rivaroxaban, a new agent for the prevention of venous thromboembolic events in orthopaedic surgery. Although the pathogenesis of SSEH is unclear, anticoagulant therapy is a known risk factor. The patient sustained a sudden onset of severe back pain in the thoracic spine, followed by paraplegia below T8, 2 days after proximal tibial osteotomy and rivaroxaban therapy. ⋯ Whilst preparing for the emergency evacuation of the SSEH, the neurological symptoms recovered spontaneously 4 h after onset without surgery. After monitored bed rest for 48 h the MRI was repeated and the SSEH was no longer present. This rare condition of spinal cord compression and unusually rapid spontaneous recovery has not previously been reported following rivaroxaban therapy.

Only 12 cases of musculoskeletal tuberculosis (TB) that occurred at the site of recent blunt trauma have been previously described. ⋯ In developing countries, where TB is still widely prevalent, there must be a heightened awareness of the risk of ST at recently fractured vertebrae, as demonstrated in this case.

The purpose of this study is to evaluate the effect of intraoperative powdered vancomycin on the rates of postoperative deep spinal wound infection. The use of intraoperative powdered vancomycin as a prophylactic measure in an attempt to reduce the incidence of postoperative spinal wound infection has not been sufficiently evaluated in the existing literature. A retrospective review of a large clinical database was performed to determine the rates of deep wound infection associated with the use of intraoperative operative site powdered vancomycin. ⋯ 15 of the 1,512 patients (0.99%) were identified as having evidence of postoperative deep wound infection. At least one pre-existing risk factor for deep infection was present in 8/15 pts (54%). Staphylococcus aureus and methicillin-resistant S. aureus (MRSA) were the most commonly identified organisms (11/15 cases). The rate of deep wound infection was 1.20% (8/663) for instrumented spinal surgeries, and 0.82% (7/849) for uninstrumented surgeries. Deep infection occurred in only 1.23% (4/324) of multilevel instrumented posterior spinal fusions, 1.37% (1/73) of open PLIF procedures, and 1.23% (1/81) of single-level instrumented posterior fusions. Deep infection was not observed in any patient who had uninstrumented spinal fusion (0/64). The deep infection rate for revision surgeries was 1.15% (1/87) and 0.55% (1/183) for trauma surgery. Increased rates of complications related to powdered vancomycin use were not identified in this series. Conclusion In this series of 1,512 consecutive spinal surgeries, the use of 1 g of powdered intraoperative vancomycin placed in the wound prior to wound closure appears to associated with a low rate deep spinal wound infection for both instrumented and uninstrumented cases. Rates of deep infection for instrumented fusion surgery, trauma, and revision surgery appear to be among the lowest reported in the existing literature. Further investigation of this prophylactic adjunctive measure is warranted.

Case Reports
Hemodialysis-related upper cervical extradural amyloidoma presenting with intractable radiculopathy.
Destructive spondyloarthropathy may occur in long-term hemodialysis patients, but focal amyloid deposits in the spine are rare. We present a case of upper cervical extradural amyloidoma with a history of long-term hemodialysis presenting with progressive and intractable radiculopathy. ⋯ Development of an upper cervical extradural amyloidoma after long-term hemodialysis is extremely rare. Prompt evaluation of long-term hemodialysis patients suffering from progressive cervical pain should be recommended, and treatment is required if there are signs or symptoms of compression of a nerve root or the spinal cord.

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.
