“…Rahimizadeh et al (17) reviewed 68 cases of C-OLF resulting in progressive quadriparesis and demonstrated that C-OLF rarely leads to cervical myeloradiculopathy. Different imaging techniques have different advantages in the diagnosis of disease (18). MRI may reveal hypertrophy of the ligamentum flavum and compression of the spinal cord in the cervical spine (18).…”

Ossification of the ligamentum flavum (OLF) is rarely observed in the cervical spine, particularly not in the upper cervical spine. The present report describes two cases of OLF combined with cervical myelopathy and provides a literature review with a comparative analysis of previous studies and the present cases. Pre-operative CT, MRI and histological examination were performed to confirm the diagnosis of these patients (A 37-year-old female and 63-year-old male). In both cases, histological examination of surgical specimens revealed OLF. The symptoms of the two patients significantly improved after surgery and no recurrence was observed at 13 months after surgery. Furthermore, the clinical outcomes were satisfactory and the internal fixation was solid in the two cases. Review of the literature suggested that further research is required to reveal the optimal treatment methods for upper cervical OLF.

“…Thereafter, correction was done using spine-to-rod method. 21,24 The anatomically contoured titan rods were inserted in the heads of pedicle screws to correct the primary curve. Finally, after tightening the rods to screws' heads, a Stagnara 25 wake-up test was performed to evaluate the neurological function of the patients.…”

“…All the structural major and minor curves were fused while non-structural compensatory curves were not included. For 10 patients with xed deformity, multiple Ponte osteotomies [15] were used to attain correction via a posterior approach. Curve correction was achieved using the direct vertebral derotation maneuver, followed by slight convex compression and concave distraction.…”

Background To evaluate the surgical outcome of younger adult idiopathic scoliosis patients (YAdIS) with selective thoracic fusion by comparing with adolescent idiopathic scoliosis (AIS). Methods Seventy-two idiopathic scoliosis patients (36 adults and 36 adolescents) treated by posterior-only all-pedicle screw technique at the same institution were retrospective reviewed and matched by curve pattern and curve magnitude. Radiographic parameters were evaluated preoperatively, postoperatively and at ﬁnal follow-up. Operating time, blood loss, transfusion and complications were noted. Clinical outcome was assessed by Scoliosis Research Society-22 questionnaire (SRS-22). Results The major thoracic curves in YAdIS group and AIS group were 56.3°±9.7°, 53.3°±10.1° and corrected to 17.2°±7.3°, 14.9°±7.5° respectively without significant difference of correction rate (69.3% vs. 72.0%). For the lumbar curve, Cobb angles in two groups were 35.6° ± 10.1° and 31.4 ± 9.2° preoperatively, and was spontaneously corrected to 18.5° ± 9.0° and 12.6° ± 8.2°. Correction rates were 48.0% and 59.8% (P＜0.05). Coronal vertebra alignments (CVA) in YAdIS group were 20.6 ± 9.7 mm before surgery and 16.8 ± 7.9 mm after surgery (P＞0.05), while CVA in the AIS group was 17.8 ± 10.5 mm preoperatively and decreased to 9.7 ± 8.3 mm postoperatively (P＜0.05). However, sagittal parameters showed significant improvements in thoracic kyphosis in both groups (P＜0.05). Complication rates were 13.9% vs. 5.6% without significant difference. Preoperative SRS score was worse in the YAdIS group than the AIS group. However, there were no significant differences between the final SRS score. Conclusions YAdIS patients gained similar correction of major thoracic curve as AIS patients, although the curve were stiffer.However,more extensive release technique needed to be done which was associated with longer operation time hospital stay. YAdIS had more complications,though this difference was not statistically significant. Patients with lower SRS score in YAdIS can also be treated very well with selective thoracic fusion surgery.
