Anterior Decompression And Fusion

✓ Anterior decompression and fusion for treating ossification of the posterior longitudinal ligament of the cervical spine was performed in 12 patients. The central part of the vertebral body and the ossified area of the posterior longitudinal ligament were removed by means of a microrongeur and an air drill. The defect was filled with a long bone graft taken from the ilium. The operative results were excellent. Marked improvement of radicular and spinal cord signs was seen in all 12 cases. Three vertebral bodies were fused in one case, four in nine cases, and five in two cases. The highest level of fusion was C-2 and the lowest was T-1. It is considered that any ossification of the ligament below the C-2 level can be removed via an anterior approach as long as no more than five vertebral bodies are involved. Spinal computerized tomography was valuable in providing more detailed information about the stenotic spinal canal and the shape of the ossified ligament.

Anterior Cervical Corpectomy

The authors report the case of a 52-year-old man who had undergone resection of an ossified posterior longitudinal ligament via the anterior approach. The patient experienced postoperative neurological deterioration that may have been caused by a massive cord herniation associated with a dural defect at the corpectomy site. Spinal cord herniation may develop as a complication of anterior cervical decompression. Surgeons should be alert to this condition when planning to treat cervical ossification of the ossified posterior longitudinal ligament via the anterior approach.

✓ A series of 283 patients who suffered from cervical spondylosis, herniated disc, or traumatic pathology of the cervical spine were operated on using an anterior approach. Intersomatic arthrodesis was performed in 350 cases; in every case, a threaded bone graft was screwed into the intervertebral orifice using the technique described by the author. Fusion was achieved within 6 months in 93% of cases with 92 autologous grafts and in 81% of cases with 258 heterologous grafts. In addition to the use of threaded intervertebral holes and threaded bone grafts, the Cloward technique was modified by the introduction of a set of new instruments, which largely replaced the ones previously in use. These included a low-speed motor with different drills and trephines, a trephine guide retractor, and an intersomatic retractor.

ABSTRACT OBJECTIVE The goal of this study was to elucidate the pathophysiological features and treatment of hypertrophy of the posterior longitudinal ligament (HPLL) of the cervical spine. HPLL is defined as a pathological thickening of the posterior longitudinal ligament (PLL), causing spinal cord compression. Incomplete decompression via removal of only coexisting herniated intervertebral discs or spondylotic spurs might be performed, resulting in unsatisfactory surgical outcomes, when the PLL becomes abnormally thickened and contributes to myelopathy. METHODS Patients with HPLL who underwent cervical decompression surgery were selected. Medical records and radiographs were retrospectively reviewed, to obtain data on the pre- and postoperative clinical conditions of the patients. Autopsy cases with HPLL proven by low-energy x-ray examinations were chosen for assessment of the pathological characteristics. RESULTS Seventeen men and three women with HPLL underwent treatment via an anterior approach, with direct removal of HPLL. Nineteen patients developed myelopathy, whereas one patient developed radiculopathy. Radiologically, all HPLL cases exhibited coexisting herniated intervertebral discs and 10 exhibited small segmental ossifications of the PLL. Magnetic resonance imaging or computed tomographic myelography revealed extensive cord compression across the vertebral endplate level. The average preoperative Benzel modified Japanese Orthopaedic Association score was 10.8, and the average postoperative score was 13.2. Histological examinations revealed thickening of the PLL with proliferation of chondrocytes, together with various degenerative changes. CONCLUSION Patients with HPLL can benefit from an anterior approach with direct removal of the HPLL and associated herniated intervertebral discs or ossification of the PLL. Cervical polytomography, computed tomography, and magnetic resonance imaging are useful in establishing a diagnosis of HPLL.

The Impact

Ossification of the posterior longitudinal ligament (OPLL) is commonly associated with diabetes mellitus (DM); however, the impact of DM on cervical spine surgery for OPLL remains unclear. This study was performed to evaluate the influence of diabetes DM on the outcomes following cervical spine surgery for OPLL. In total, 478 patients with cervical OPLL who underwent surgical treatment were prospectively recruited from April 2015 to July 2017. Functional measurements were conducted at baseline and at 6 months, 1 year, and 2 years after surgery using JOA and JOACMEQ scores. The incidence of postoperative complications was categorized into early (≤30 days) and late (>30 days), depending on the time from surgery. From the initial group of 478 patients, 402 completed the 2-year follow-up and were included in the analysis. Of the 402 patients, 127 (32%) had DM as a comorbid disease. The overall incidence of postoperative complications was significantly higher in patients with DM than in patients without DM in both the early and late postoperative periods. The patients with DM had a significantly lower JOA score and JOACMEQ scores in the domains of lower extremity function and quality of life than those without DM at the 2-year follow-up.
